Full textIn the therapy of coronary heart disease minimally invasive and endoscopic methods offer considerable benefits to the patient, while for the surgeon difficult orientation and missing haptic feedback are still the leading problems in Endoscopic Bypass Grafting with telemanipulative systems. To support the surgeon with improved vision, a three dimensional model of the coronary artery tree based on CT scans is integrated into the view of the endoscope. The “Surgical Cartographic Navigation System” (SCNS) is a tool which provides this feature called Augmented Reality (AR). Aim of this study was the first technical analysis of the SCNS during a simulation of an incision with the da Vinci™ surgical system on an electronic heart phantom. The hypotheses was that with the guidance of the SCNS augmented reality view, the surgeon can perform a direct contact to the Left Anterior Descending Coronary Artery (LAD). Five anatomically correct heart phantoms were created using the rapid prototyping technology. The heart models were covered with an electrical conducting layer for the detection of the contact with the coronary artery or with the surrounding tissue. A 3D model of the coronary artery tree based on a CT scan was registered to the heart phantom and overlaid into the video screen of the da Vinci™ robot master console. Ten inexperienced medical students and ten experienced heart surgeons used the SCNS in a surgery simulation with the goal of finding the LAD artery and contacting the LAD with robot instruments. In 300 test runs 58 % of both groups hit the LAD correctly. The overlaid information created with the SCNS enables the surgeon to correctly identify the coronary artery. The clinical applicability of the SCNS for the TECAB Operation is hereby demonstrated. These findings are the basis for further studies on the further development of the SCNS, that is necessary before a clinical first-use

Full textEsta dissertação apresenta uma abordagem cartográfica para o problema de roteamento de veículos dinâmico com janelas de tempo e clientes estocásticos (DVRPTWSC, por sua sigla em inglês). Os objetivos considerados são minimizar o tempo total de viagem e maximizar o número de pedidos novos atendidos. Para abordar o DVRPTWSC é necessário resolver o problema de roteamento de veículos com janelas de tempo (VRPTW, por sua sigla em inglês). Assim, para tratar o VRPTW propõe-se um algoritmo memético (MA, por sua sigla em inglês). O MA reduz o espaço de busca usando informação obtida por meio de um procedimento de clusterização, o qual é aplicado aos dados espaciais dos clientes. Para o DVRPTWSC, a abordagem cartográfica é incorporada em um sistema multiagente, no qual um agente roteirizador planeja as rotas para os agentes veículos. O processamento cartográfico é aplicado antes de criar o plano de rotas inicial para o DVRPTWSC. Este procedimento usa clusterização hierárquica para dividir a região onde estão os clientes em uma hierarquia de regiões encaixadas. O plano de rotas inicial considera pedidos conhecidos e pedidos potenciais amostrados de distribuições de probabilidade conhecidas. Para obter o plano de rotas inicial, usam-se os operadores de busca do MA, os quais utilizam a informação obtida da clusterização hierárquica para fazer a busca. Ao longo do horizonte de planejamento, o roteirizador atualiza o plano de rotas: Pedidos potenciais que foram considerados no plano de rotas inicial e que não foram consolidados são removidos e novos pedidos são incluídos usando o procedimento assignation of requests based on nested regions (ARNR). O procedimento ARNR visa reduzir o número de veículos considerados para atender novos pedidos. Para isso, tenta designar os novos pedidos aos veículos disponíveis para o atendimento que possuem os menores custos de desvio da rota pré-determinada. As regiões encaixadas criadas no processamento cartográfico são utilizadas para identificar esses veículos. Para o VRPTW, resultados experimentais mostram que o MA proposto é competitivo com métodos do estado da arte. A abordagem proposta para o DVRPTWSC supera abordagens que não incluem pedidos potenciais no plano de rotas inicial. O uso do procedimento ARNR reduz significativamente o número de veículos considerados para atender novos pedidos, e produz soluções similares às produzidas quando se consideram todos os veículos em operação. A abordagem desenvolvida para o DVRPTWSC tem um desempenho consistente para três níveis de dinamismo: baixo, médio e alto.

Full textMaps show geographic information of a given area in a simplified way, particularly when the scale is small. The simplification process, called cartographic generalisation, is submitted to several constraints : legibility, adequation to the abstraction level, and consistency with reality. The will to automate the maps creation process from geographical databases led to the creation of algorithms allowing the simplification object by object. However the choice of the algorithms, as their settings, are influenced by the object on which it is applied, and by the other objects in relation with this object (e.g. a building close to another one, a road parallel to a buildings alignment). This motivates the use of multi-agents models for automated map generalisation. Several multi-agent models were proposed, each of them having a different approach to manage multi-levels relations. Here, what we call a level is, for instance, the distinction between individual agents, like a building, and agents representing a group of other agents, like a urban block composed by the surrounding roads and buildings inside.We study the unification of existing models, using the multi-level paradigm PADAWAN, in order to simplify interactions between agents in different levels. We propose the DIOGEN model, in which the principle of interactions between agents of different levels is adapted to cartographic generalisation guided by constraints, those allowing to unify the existing models AGENT, CartACom and GAEL, and giving promising features.We evaluate our proposal on different case studies. Among them, we study the generalisation of trekking maps, where the routes are symbolized individually by a different couloured line symbols, like on bus maps. The presence of several route symbols on a same road leads to specific generalisation issues, like the choice of the side of each route symbol position, or the implications for the other objects on the map (e.g. points of interest, buildings) under the route symbol – issues tackled using our proposal of formal multi-levels representation.This work leads us to the identification of recurrent behaviours. We express them as analysis patterns, in a way that is independent from cartographic generalisation and constraint solving problems

Full textAbstract: The aim of this research is to design and implement an automatics multi-scale and audio-dynamic map for an In-Car Route Guidance and Navigation System (RGNS). The design was organized in two stages: general composition and auditory-graphic design. The visual-dynamic maps were designed based on cartographic communication principles and visual perception, especially on the generalization operators. The area of study presents an urban network with different types of roads, nodes, and speed limits. The maps were designed for a small-screen display, and a total of four different scales were employed: 1:10.000, 1:5.000, 1:2.500 and 1:1.000. These scales were chosen according to the media size and type of tactical task. The maps were derived from an accurate cartographic database at scale of 1:1000, by applying generalization techniques, such as simplification, displacement, and enhancement. The audio-dynamic representations were produced by taking account a set of audio-dynamic variables. The voice messages were recorded in a female voice, and they were presented with visual information, simultaneously. The design was implemented in a navigation system, which is available in the Faculty of Sciences and Technology, by using Visual Basic compiler and MapObjects library. The results of comparison between the automatic multiple-scale and single scale system show that the new system, enhanced driver's context, can allow the user receiving information according to the tasks performed along of the route. From the employment of generalization technique it was possible to present in a properly way the amount of information in the display, in which it can contribute for reducing navigational errors and visual demand, when compared with single-scale map ...

Full textThe purpose of this thesis is to modelize the literary space using geomatics methods and quantitative tools. Due to the complexity and spatiality of the Cycle de Nedjma by Kateb Yacine (1929- 1989), we intended to develop non-linear knowledges and representations in order to explore differently the literary work. The purpose of this thesis is also to show the specific role of the narrative in the construction of its own geography. This proposal is based on a detailed study of potentialities of a spatial modelization in geographic and literary fields. This work is based on three main hypothesis: the fact that “literary space” is indeed a real space; the fact that partitions between different definitions of space can beovercome; and finally the fact that studying the relationships between those spaces can enlighten us about the functioning of the narrative. The methodology consisted in producing a geographic database that would be able to formalize, index and represent the geographic and narrative data extracted from the novel Nedjma. The resulting set of maps shows the co-construction of the geographic and the literary katebian spaces. Indeed, through proximity and bursting narrative effects, Algerian space is reconfigured, setting the basis of a more open and reticular Algerian nation

A interpretação de um mapa é facilitada com a utilização de textos, os quais facilitam a comunicação do mapa. Os mapas de Sistema de Navegação e Guia de Rota em Automóvel (SINGRA) utilizam textos na área mapeada com a finalidade de auxiliar o motorista na tarefa de navegação. Os nomes de vias são um dos elementos mais importantes no uso como informação de guia de rota. A literatura na área da Cartografia apresenta recomendações para rotular feições cartográficas em mapas estáticos. Porém, os mapas exibidos em SINGRA são dinâmicos e apresentados em um esquema de referência egocêntrica. Então, é questionado se as indicações propostas pela literatura podem ser generalizadas para esse tipo de representação. Este trabalho avalia o tempo de leitura de nomes de vias em mapas de SINGRA, levando-se em consideração diferentes posicionamentos da toponímia de via em mapas com diferentes padrões de malha viária. Para esta avaliação foram projetados 16 mapas, oito com padrão de malha viária regular e oito com padrão de malha viária irregular. Um conjunto apresentou nomes de vias com posicionamento alinhado horizontalmente e outro com os nomes seguindo a via. A concepção dos mapas foi baseada em princípios de agrupamento perceptível, segregação de figura-fundo, bem como em técnicas de tipografia, uso de tipos na cartografia e, também, na análise de mapas de sistemas de navegação de ampla utilização no mercado. A avaliação foi realizada com 20 motoristas novos. O experimento ocorreu dentro de um automóvel estacionado. A tarefa do participante foi buscar um nome de via no mapa exibido em uma tela de pequenas dimensões, bem como falar em voz alta o nome da via solicitada pelo pesquisador. A duração do tempo de leitura foi extraída e analisada. Em mapa com padrão de malha viária regular, a análise estatística mostrou que não houve diferença significativa no tempo de leitura entre os diferentes posicionamentos do texto, tanto para o nome da via em que se encontra quanto para o nome da via em que irá entrar. Por outro lado, em mapa com padrão de malha viária irregular e nome com o posicionamento alinhado horizontalmente, a análise estatística dos dados revelou que o tempo de leitura do nome da via em que o motorista irá entrar é significativamente mais rápido do que a leitura do nome da via em que se encontra. Maiores implicações são apresentadas e discutidas.
Reading a map is facilitated by using texts, which facilitate the communication of the map. InCar Route Guidance and Navigation System maps (RGNS) use texts in the map to assist drivers in the navigation task. Road names are one of the most important elements in the use as route guidance information. The literature in the Cartography field presents recommendations for labeling cartographic features in static maps. However, maps showed in RGNS are dynamic and presented in an egocentric reference. Thus, it is questioned whether those results can be generalized to this kind of representation. This work evaluates the time in which drivers start reading road names in maps of RGNS, taking into account different positions for the road toponymy in maps with different road network patterns. For this evaluation, 16 maps were designed; eight with road pattern similar to a regular-grid network and eight with road pattern similar to an irregular-grid network. Half of the maps were designed with names aligned horizontally and the other half with names following the road. Creating maps was based on principles of perceptual grouping, figure-ground segregation, as well techniques of typography, use of types in Cartography and, also, in the analysis of some maps of navigation systems with high acceptance in the market. The evaluation was performed with 20 drivers aged between 20 and 30 years. The experiment took place inside a car parked. The task of the participant was looking for a street name showed in a small screen and speech in a loud voice the name requested by the researcher. The time took to start reading was gathered an analyzed. For maps with road pattern similar to a regular-grid network the analysis showed no significant difference in the time in which drivers start reading road names among different text positioning, both for road name where they are located and for road name where they will turn. On the other hands, for maps with road pattern similar to an irregular road network and name aligned horizontally, the statistical analysis revealed the reading time for the name in which drivers will turn is significantly faster than reading time for the name in which drivers are located. More implications are presented and discussed.

Full textNär en karta skapas baseras mängden data och vilken geografisk information som skaförmedlas beroende på syftet med kartan. Trafikverket ansvarar för den NationellaVägdatabasen som är ett referensvägnät med en stor mäng data kopplad till vägnätet.Referensvägnätet är byggt på en körbanenivå. I det här arbetet har databasen studerats ochvilka möjligheter som finns för att skapa en automatisk generalisering till vägnivå. Det finnsett behov att representera data på en annan detaljnivå för vissa applikationer och analysersom använder sig av vägdatabasen. Det är även viktigt utifrån ett kartografiskt synsätt.Möjligheterna att skapa en linjär referering mellan de olika detaljnivåerna har undersökts, föratt förenkla uppdateringar mellan nivåerna samt att inte behöva ajourhålla två olikadatabaser. Det skulle även göra det möjligt att attribut och företeelser kan ärvas mellan deolika nivåerna.Det fösta helt automatiserade arbetsflödet för en generalisering av en karta utformades 2014i Nederländerna. Flera andra myndigheter i Sverige och Norge arbetar just nu med den härtypen av generaliseringar och har använt sig av olika tillvägagångssätt. Statens Vegvesen,vilket är den statliga myndighet som ansvarar för vägar i Norge, har redan implementerat olikadetaljnivåer i deras vägdatabas. Lantmäteriet har ett projekt med målet att skapa en fulltautomatisk generalisering för olika skalor.Efter att ha studerat de olika program som vanligtvis används vid generaliseringar samt vilkaprogram som Trafikverket använder sig av så valdes FME och ArcGIS i det här arbetet. Ettmindre studieområde valdes ut och relevant data hämtades från den NationellaVägdatabasen. Studien bestod av olika experiment och tester av olika parametervärden föratt få ett acceptabelt resultat.Tre olika områden studerades, där målet var att hitta en följd operationer som skapade enlämplig generalisering för alla områden. De tre olika områdena var parallella vägar,trafikplatser och cirkulationsplatser. Resultatet består av förslag på ett arbetsflöde, men delarhar behövt göras manuellt då det inte var möjligt att hitta en helt automatiseradgeneralisering för det valda området. Förslag på olika funktioner och verktyg som kanutvecklas har sammanställts, för att kunna utvecklade ett mer automatiserat arbetssätt.Resultatet av det här arbetet visar att om kartografiska generaliseringar studeras och testasmer skulle det kunna vara möjligt att skapa ett mer automatiserat arbetssätt med syfte attmöjliggöra generaliseringar mellan olika detaljnivåer. Det kan däremot vara svårt att få dettahelt automatiserat på grund av de olika komplexa trafikplatserna.

Full textBy knowing what clinical research is undertaken worldwide, where it is conducted, which diseases are studied, and who is supporting it, we could have a better understanding on how is created the knowledge concerning health interventions. A global landscape of health research may inform policy makers on knowledge gaps and on how to reallocate resources to address health needs, in particular in low-resource settings. In this thesis we mapped clinical research, i.e. we analyzed at a macro-level the complex system of health research to bring information on the global landscape of health research effort. We based our analyses on clinical trial registries included in the International Clinical Trials Registry Platform from the World Health Organization. In a first project, we evaluated within 7 regions the local alignment between the effort of research and the burden for 27 groups of diseases. This work needed the development of a knowledge-based classifier of clinical trial registries according to diseases studied based on natural language processing methods. We mapped 117,180 randomized controlled trials. For high-income countries, the research effort was well aligned with the needs. In all other regions we identified research gaps. In particular, for Sub-Saharan Africa, where major causes of burden such as HIV and malaria received a high research attention, research was lacking for major causes of burden, especially for common infectious diseases and neonatal disorders. In a second project, we compared the mappings of multi-country trials for industry- and non-industry–sponsored clinical trials, and analyzed the networks of collaboration of countries participating together to the same multi-country trials. We showed that among industry- and non-industry–sponsored trials, 30% and 3% were multi-country, respectively. The collaboration within Eastern European countries was particularly over-represented for industry-sponsored research. Industry sponsors may thus have a greater capacity to conduct globalized research, using well-defined networks of countries. Our large-scale mappings of all registered clinical trials shed light on major gaps in the effort of health research as compared to health needs. In addition, we showed the influence of different sponsors in the globalization of clinical research. These projects are in-line with the development of a global observatory for health research

O objetivo desta pesquisa consiste na elaboração de mapas áudio-dinâmicos em múltiplas escalas automáticas, para um Sistema de Navegação e Guia de Rota em Automóvel (SINGRA). O projeto das representações cartográficas foi dividido em duas fases: projeto de composição geral e projeto áudio-gráfico. Os mapas visuais dinâmicos foram elaborados com base nos princípios da comunicação cartográfica e da percepção visual, com ênfase nas operações de generalização. A área de estudo apresenta uma malha urbana com diferentes tipos de vias, cruzamentos e limites de velocidade. Os mapas foram projetados para serem exibidos em um monitor de pequeno formato (sete polegadas), com alta resolução, e um total de quatro escalas de representação foi determinado: 1/10.000, 1/5.000, 1/2.500 e 1/1.000. Tais escalas foram definidas em função do tamanho da mídia de apresentação e do tipo de tarefa tática. Os mapas generalizados foram obtidos pela aplicação das operações de simplificação, exagero e deslocamento, sobre uma base cartográfica na escala 1/1.000.

Yan, Jingya. "An ontologies and agents based approach for undersea feature characterisation and generalisation." Thesis, Brest, 2014. http://www.theses.fr/2014BRES0031/document.
Full textA nautical chart is a kind of map used to describe the seafloor morphology and the shoreline of adjacent lands. One of its main purposes is to guaranty safety of maritime navigation. As a consequence, construction of a nautical chart follows very specific rules. The cartographer has to select and highlight undersea features according to their relevance to navigation. In an automated process, the system must be able to identify and classify these features from the terrain model.An undersea feature is a subjective individuation of a part of the seafloor. Landform recognition is a difficult task because its definition usually relies on a qualitative and fuzzy description. Achieving automatic recognition of landforms requires a formal definition of the landforms properties and their modelling. In the maritime domain, the International Hydrographic Organisation published a standard terminology of undersea feature names which formalises a set of definitions mainly for naming features and communication purpose. This terminology is here used as a starting point for the automatic classification of the features from a terrain model.In order to integrate knowledge about the submarine relief and its representation on the chart, this research aims to define ontologies of the submarine relief and nautical chart. Then, the ontologies are applied to generalisation of nautical chart. It includes two main parts. In the first part of the research, an ontology is defined to organize geographical and cartographic knowledge for undersea feature representation and nautical chart generalisation. First, a domain ontology of the submarine relief introduces the different concepts of undersea features with their geometric and topological properties. This ontology is required for the classification of features. Second, a representation ontology is presented, which describes how bathymetric entities are portrayed on the map. Third, a generalisation process ontology defines constraints and operations in nautical chart generalisation. In the second part, a generalisation process based on the ontology is designed relying on a multi-agent system. Four kinds of agents (isobath, sounding, feature and group of features) are defined to manage cartographic objects on the chart. A database model was generated from the ontology. The bathymetric data and the ontology are stored in a triplestore database, and are connected to an interface in Java and C++ to automatically classify the undersea features extracted from the bathymetry, and evaluate the cartographic constraints. At first, geometrical properties describing the feature shape are computed from soundings and isobaths and are used for feature classification. Then, conflicts are evaluated in a MAS and generalisation plans are provided

Full textThe Department of Water Affairs and Forestry (DWAF) acquired a Geographic Information System (GIS) in 1987. The purpose of acquiring such a system was to aid the department in implementing their water resource management strategy of that time. On acquiring this system it was well recognised that the GIS would need to communicate geo-referenced information, generated by analysis and modelling to decision makers by means of graphic representations or maps (Olivier et al., 1990: 14 73). Towards the end of 1990 it became apparent that the department needed to standardise cartographic output of this system. Maps on the same theme, which were produced at different sites were not comparable and graphic communication was not effective. A consultant was appointed, who, in conjunction with the departmental digital cartographer, established criteria and standards which were flexible enough to accommodate mapping on a wide variety of themes. These standards were implemented, to a limited extent in July 1994. Standards were set for map encoding, map content and map composition. This report investigates how effective these standards have been. The effectiveness of these standards have been measured in terms of the five recognised cartographic design principles that have been identified by Robinson et al. (1984), Wood (1992) and Dent (1990). These include the clarity and legibility of maps, the distinction between figure and ground, the hierarchical organisation of mapped information, the visual contrast of marks on maps and the visual balance or layout of the finished map. A sample of maps made after the implementation of cartographic standards at the department was compared to a sample of comparable maps made prior to the implementation of these standards. In a large organisation like the department the success of such standards do not depend on the standards alone but also on their implementation. Implementation related problems were identified by comparing standardised maps with the standards. The outcome of the investigation proved that the effectiveness of graphic communication had indeed improved albeit to a varying degree. In most cases the standards were adequate and the main problems actually lay with their implementation. Recommendations on the implementation and the few aspects of the standards that require amendment have been included in this report.

Full textThis work aims to study the problem of air-ground robotic cooperation for collaborative traversability mapping. The need for a map for navigation and path planning for terrestrial robots is no longer to be proven. The use of air-ground cooperation to create a navigable map for the ground robots has several interests. First, the drone can quickly map an area through its large field of vision and traveling capabilities. Second, the fusion of maps based on these two agents makes it possible to draw the best benefits from both points of views: the coherence of the global aerial view and the accuracy of the local ground view. To answer this problem, we propose a method that relies on the construction of a unified model of hybrid maps and their fusion.The maps are built using the skeleton of the traversability space as a support for graphs also containing local metric and potentialy semantic information of the environment. The maching of aerial and ground maps is done using a point to point correlation based on an appropriate dissimilarity measure. This measure is defined to meet invariance and discriminance criteria. The matching is then used to merge the maps into an augmented traversability map. The merged maps can be used by the ground robot to perform its mission. They also make it possible to deploy information such as GPS coordinates to robots in GPS denied environments. Experiments in virtual and real world environments have been carried out to validate this approach and map out future perspetives

Full textAbstract Internet is a fast growing medium to get and disseminate geospatial information. It provides more and more web mapping services accessible by thousands of users worldwide. However, the quality of these services needs to be improved, especially in term of personalization. In order to increase map flexibility, it is important that the map corresponds as much as possible to the user’s needs, preferences and context. This may be possible by applying the suitable transformations, in real-time, to spatial objects at each map generation cycle. An underlying challenge of such on-the-fly map generation is to solve spatial conflicts that may appear between objects especially due to lack of space on display screens. In this dissertation, we propose a multiagent-based approach to address the problems of on-the-fly web map generation and spatial conflict resolution. The approach is based upon the use of multiple representation and cartographic generalization. It solves conflicts and generates maps according to our innovative progressive map generation by layers of interest approach. A layer of interest contains objects that have the same importance to the user. This content, which depends on the user’s needs and the map’s context of use, is determined on-the-fly. Our multiagent-based approach generates and transfers data of the required map in parallel. As soon as a given layer of interest is generated, it is transmitted to the user. In order to generate a given map and solve spatial conflicts, we assign a software agent to every spatial object. Then, the agents compete for space occupation. This competition is driven by a set of priorities corresponding to the importance of objects for the user. During processing, agents take into account users’ needs and preferences in order to improve the personalization of the final map. They emphasize important objects by improving their legibility and using symbols in order to help the user to better understand the geographic space. Since the user can stop the map generation process whenever he finds the required information from the amount of data already transferred, his waiting delays are reduced. In order to illustrate our approach, we apply it to the context of tourist web and mobile mapping applications. In these contexts, we propose to categorize data into four layers of interest containing: explicitly required objects, landmark objects, road network and ordinary objects which do not have any specific importance for the user. In this dissertation, our multiagent system aims at solving the following problems related to on-the-fly web mapping applications: 1. How can we adapt the contents of maps to users’ needs on-the-fly? 2. How can we solve spatial conflicts in order to improve the legibility of maps while taking into account users’ needs? 3. How can we speed up data generation and transfer to users? The main contributions of this thesis are: 1. The resolution of spatial conflicts using multiagent systems, cartographic generalization and multiple representation. 2. The generation of web and mobile maps, on-the-fly, using multiagent systems, cartographic generalization and multiple representation. 3. The real-time adaptation of maps’ contents to users’ needs at the source (during the first generation of the map). 4. A new modeling of the geographic space based upon a multi-layers multiagent system architecture. 5. A progressive map generation approach by layers of interest. 6. The generation and transfer of web and mobile maps at the same time to users.

Other units, linear,specific or surface can be highlighted by a direct confrontation with the land.The analysis was carried out on the “ligérienne” part of the old industrial valley of Gier.The method implements a Geographical Information system (GIS) historical whichauthorizes integration, the reinterpretation and the crossing of information coming fromvaried sources: serial, textual, cartographic or iconographic. This tool facilitates thedivision and the update of the produced data.The results obtained have offered a reading of the evolution of the valley of Gier on theplot scale for two centuries. They propose a new approach of the territory and its evolutionwhich makes it possible to question the patrimonial policies or of installation existing.Extended to the whole space of the agglomeration of Saint-Etienne or to other territoriesand regularly updated, the method can make it possible to constitute an observatory oftheir evolution

Full textThe last decade has seen the emergence of many Unmanned Aerial Vehicles (UAV) which are becoming increasingly cheap and miniaturized. A mounted video-camera is standard equipment and can be found on any such UAVs. In this context, we present robust techniques to enhance autonomy levels of airborne vision systems based on mini-UAV technologies. First, we present a camera autocalibration method based on central projection based image \dimension{2}-invariants analysis and we compare it to classical Dual Image of the Absolute Conic (DIAC) technique. We present also a method to detect and calibrate turret's effectors hierarchy. Then, we propose a new algorithm to extract a calibrated camera self-rotation (visual gyroscope) and we apply it to propose a real-time video stabilizer with full perspective correction

Full textThis thesis addresses easy and effective development of mapping and transportation applications which especially focuses on the generation of pedestrian networks for applications like navigation, itinerary calculation, accessibility analysis and urban planning. In order to achieve this goal, we proposed a two layered data model which encodes the public space into a hierarchy of semantic geospatial objects. At the lower level, the 2D geometry of the geospatial objects are captured using a planar partition which is represented as a topological 2D arrangement. This representation of a planar partition allows efficient and effective geometry processing and easy maintenance and validation throughout the editions when the geometry or topology of an object is modified. At the upper layer, the semantic and thematic aspects of geospatial objects are modelled and managed. The hierarchy between these objects is maintained using a directed acyclic graph (DAG) in which the leaf nodes correspond to the geometric primitives of the 2D arrangement and the higher level nodes represent the aggregated semantic geospatial objects at different levels. We integrated the proposed data model into our GIS framework called StreetMaker together with a set of generic algorithms and basic GIS capabilities. This framework is then rich enough to generate pedestrian network graphs automatically. In fact, within an accessibility analysis project, the full proposed pipeline was successfully used on two sites to produce pedestrian network graphs from various types of input data: existing GIS vector maps, semi-automatically created vector data and vector objects extracted from Mobile Mapping lidar point clouds.While modelling 2D ground surfaces may be sufficient for 2D GIS applications, 3D GIS applications require 3D models of the environment. 3D modelling is a very broad topic but as a first step to such 3D models, we focused on the semi-automatic modelling of objects which can be modelled or approximated by generalized cylinders (such as poles, lampposts, tree trunks, etc.) from single images. The developed methods and techniques are presented and discussed

Full textIn the brain, the visual system includes the Lateral Geniculate Nucleus, the Superior Colliculus and the visual cortex. These structures have been studied since the 50’s and these studies have relied on functional MRI but also on the development of functional surface microscopic imaging techniques. To examine the spatiotemporal resolution of the ultrafast ultrasound imaging technique, we measured visual responses in in the cerebral structures on anesthetized rats in one imaging plan or with a 3D reconstruction. After having validated our technology on rodents, we have applied the technique to awake non-human primate visual cortex. We reconstructed the retinotopic maps of visual cortex, at the surface and in depth. In addition, we could resolve the ocular dominance columns within V1, which represent a major functional structuration in the primary visual cortex. This functional observation suggests the presence of ocular dominance beyond layer 4 in layers 3 and 5 of V1. In conclusion, this thesis work has demonstrated that the functional ultrafast ultrasound imaging can measure activity in the visual system for both rats and non-human primates, anesthetized and awake. This new imaging technique can provide functional measures with a high spatiotemporal resolution in the deep tissue. This illustration on the visual system highlights the potential of the technique to measure functional units not accessible to optical surface analysis and below the resolution of fMRI. Future studies will have to define if this technique can still provide a better resolution than fMRI in deeper structures than 1cm

Abstract: This research proposes a new technique for close-range mobile data acquisition and processing, consisting of a backpacked light-weight low-cost system. This system integrates an omnidirectional camera and a GPS/IMU system (Global Positioning Systems/Inertial Measurement Unit System) with a tailored photogrammetric processing chain to obtain sensor location and 3D points coordinates using the fisheye images. Omnidirectional systems, based on multiple cameras covering a full-spherical field of view, have been used in close range photogrammetry applications. The use of omnidirectional systems is especially motivated by their 360° coverage around the sensor, which allows more features to be tracked in a single image shot, and by the light weight and low cost of some off-the-shelf omnidirectional cameras. This kind of systems have been named as Personal Mobile Terrestrial System (PMTS). There are only few studies focusing on PMTS using omnidirectional systems. This research assessed the performance of an omnidirectional PMTS based exclusively on low-cost technologies to indirectly estimate forest and outdoor urban features. An accuracy evaluation of GPS and IMU sensors and the development of rigorous photogrammetric processing considering fisheye geometry were performed. PMTS data, i.e fisheye images and navigation data, are input information for the photogrammetric process. The proposed photogrammetric process focused on omnidirectional camera modelling, feature-based matching an... (Complete abstract click electronic access below)
Resumo: Este trabalho propõe uma nova técnica para aquisição e processamento de dados obtidos com um sistema de mapeamento móvel terrestre leve e de baixo custo embarcado em mochila, conhecido como PMTS (Personal Mobile Terrestrial System - Sistema de Mapeamento Móvel Pessoal). O sistema de mapeamento móvel proposto é composto por uma câmara omnidirecional (imagens fisheye) e um sistema de navegação GPS/IMU (Global Positioning Systems/ Inertial Measurement Unit System). As imagens do tipo fisheye e os dados de navegação coletados com o PMTS são utilizados em um processo fotogramétrico adaptado para a geometria das imagens fisheye para obter a posição do sensor e as coordenadas tridimensionais (3D) do ambiente mapeado (nuvem de pontos). Sistemas omnidirecionais baseado em múltiplas câmaras vêm ganhando visibilidade em diversas aplicações na Fotogrametria a curta distância, como a navegação autônoma e o mapeamento móvel de cidades, floresta e ambientes internos. O uso de múltiplas câmaras é principalmente motivado pelo seu amplo campo de visada (360°), sua portabilidade, o baixo custo de algumas câmaras disponíveis no mercado e seu sistema óptico compacto, sem a necessidade de espelhos externos (sistema catadióptricos) ou dispositivos rotativos (câmaras de varredura por rotação). No entanto, existem poucos estudos voltados ao desenvolvimento de PMTS usando sistemas omnidirecionais.
