Dissertations / Theses on the topic 'Lighting automation'

Lighting simulation contribute readily to the synthesis of high performance lighting designs. Unfortunately there exist several issues impeding the pervasive use of lighting simulation, including: Most of the time in preparing lighting simulations is spent towards the input of existing but non-interoperable information between different tools. Lighting simulation tools do not complement integrated building design processes where the design solution is progressively developed in multiple disciplines concurrently; lighting simulation tools require design information (attributes) that may not yet be defined, and is non-interoperable with other tools. . Disparate tools with vastly different technical approaches available for different stages of the building design process do not allow consistent or meaningful performance comparisons between design versions, and similarly makes design performance progress tracking between design versions difficult. Lighting simulation tools provide radiance and irradiance values as simulation results, and much time and manual effort is required to process these results into operative information, information that is directly applicable in making design decisions. Lighting simulation tools employ outdated rendering techniques that are inadequate in evaluating highly-reflected irradiance, a typical feature in high performance building designs. While there remain other shortcomings in lighting simulation tools as identified by contemporary research3, the issues above relate closely to the overall effort and time-cost factors attributed to using simulation tools, which has been consistently identified as obstacles towards using simulation tools. This research seeks to reduce the effort and time-cost required to conduct lighting simulation by addressing the issues above. Case studies of actual design scenarios are used to establish quantitatively the effort and time costs baselines for comparison. The effort and time reduction goal is structured as the following objectives in a new lighting design support tool: Reduce the time and effort to set up and conduct lighting simulation by using interoperable information (building information models) from design modeling tools. Complement integrated design processes by supporting design models of varying completeness5, in a format that is interoperable with tools from other disciplines in the design team. All information, including assumptions, must be consistent across all disciplines. Provide ability to use performance metrics and consistent technical approaches throughout design stages, regardless of completeness of design model. Provide operative information with minimum user effort. Implement a first principle-based rendering technique that handles high performance building designs well, and produce simulation results within reasonable time constraints. By meeting these objectives, the new lighting design tool is able to automate much of the previously manual, time-consuming, and disparate efforts in lighting simulation, thus reducing the effort and time-cost. By sharing interoperable information with other tools across the design team, the new lighting design tool is integrated. The new tool is also scalable in being able to support models of varying completeness throughout all design stages.

This paper discuss the design and realisation of intelligent lighting system for home automation. Identifying the most adequate solution of system implementation is followed by choosing suitable components, design of electrical circuits and printed circuit boards. The project then deals with development of software for each particular device in the system and development of computer application for managing the system. The paper also treats with mechanical design and construction of devices in the system.

When reviewing the technical literature, a study of existing lighting controls systems, their advantages and disadvantages. Two methods of lighting control were also investigated: employment sensing and light sensing, which are then used to develop the system. According to the results of the analysis of the technical task and review of scientific and technical literature, the relevance of creating a lighting control system was confirmed, which will automate the lighting of premises and will be a profitable solution in terms of energy-saving. As a result of the review, it was decided to use two types of sensors in the system in parallel: light sensors and motion sensors. Variant lighting control options have been developed using wired and wireless communication between components and a decision has been made to use a mixed type of communication. The structural scheme of the adaptive lighting control system, the algorithm of this system operation is developed and the code for software connection of system components is written. It is possible to further refine this system for outdoor lighting control and in more complex adaptive control algorithms, taking into account data from sensors of biotelemetric quantities that take into account user characteristics.

The focus of this thesis is to explore the automation technology used in the modern entertainment industry. Upon completion of my thesis, I will deliver a working prototype of the chosen technology and present its capabilities in a choreographed show.

В даній кваліфікаційній роботі розроблено однокаскадне джерело живлення для вуличних світлодіодних світильників загального призначення. Створений пристрій забезпечує стабільний вихідний струм величиною 350 мА. Блок живлення спроектований на основі мікросхеми UCC28810 компанії Texas Instruments і забезпечує максимальну вихідну потужність 80 Вт та живиться від мережі змінного струму з номінальною напругою 220 В. Наявність в даній мікросхемі вбудованої функції корекції коефіцієнта потужності дозволило реалізувати перетворювач з коефіцієнтом потужності (КП) – 0,9 без використання додаткового коректора. Імпульсний перетворювач напруги побудований по технології SEPIC і, відповідно, немає гальванічної ізоляції між входом і виходом. Проте, це допустимо для вуличних світильників. В імпульсному блоці живлення передбачений захист від перенапруг та обриву навантаження.
In this qualification work a single-stage power supply for general purpose LED street lamps has been developed. The created device provides a stable output current of 350 mA. The power supply is designed based on the UCC28810 chip from Texas Instruments and provides a maximum output power of 80 watts and is powered by AC mains with a nominal voltage of 220 V. The presence of a built-in power factor correction function in this chip allowed to implement a converter with a power factor (KP) of 0.9 without the use of an additional corrector. The pulse voltage converter is built on SEPIC technology and, accordingly, there is no galvanic isolation between input and output. However, this is acceptable for street lamps. The switching power supply provides protection against overvoltages and load breakage.

Resumo: No Brasil, as edificações são responsáveis por 45% do consumo de toda energia elétrica produzida no país, sendo 14,6% representado pelo setor comercial. Neste setor, os sistemas de iluminação artificial representam em média 22% do consumo de energia, apresentando grandes possibilidades para ações de eficiência energética. Estudos mostram que é possível reduzir 61% do custo com energia elétrica com ações de eficiência energética em sistemas de iluminação. Levantamentos realizados pelo Procel indicam que nos hipermercados 66,7% possuem potência instalada em iluminação acima de 100 kW, oferecendo grandes oportunidades para ações de eficiência energética no setor de iluminação. A integração da iluminação artificial com a natural possibilita grandes reduções nos custos com energia elétrica, além de proporcionar ambientes mais agradáveis e saudáveis para seus usuários. Ainda, estudos ressaltam que nos projetos luminotécnicos em geral, a eficiência energética do conjunto de equipamentos luminária-lâmpada-reator não costuma ser considerada, sendo comum a adoção de lâmpadas eficientes com luminárias ou reatores pouco eficientes. Neste trabalho, foram analisados dois hipermercados localizados na cidade de Campo Grande - MS. O hipermercado B possui um sistema de aberturas zenitais que possibilita o aproveitamento da iluminação natural e um conjunto de luminárias com refletores brancos e lâmpadas fluorescentes tubulares T8, enquanto o hipermercado A possui um sistema de fechamento com forro e um conjunto de luminárias com refletores metálicos e lâmpadas fluorescentes tubulares T5. Para realizar uma avaliação visando à eficiência energética de ambos os sistemas de iluminação destes hipermercados foram realizados levantamentos em campo, medições do consumo de energia elétrica nos circuitos de iluminação e também medições da distribuição dos níveis internos de iluminâncias. O estudo conclui que o aproveitamento da iluminação natural, associada ao correto dimensionamento do conjunto lâmpada luminária- reator e uso de sistemas automatizados oferecem grandes potenciais para a eficiência energética
Abstract: Buildings in Brazil are responsible for 45% of the whole electrical energy consumption, where 14,6% are performed in commercial buildings. In this sector, artificial lighting represent about 22% share of their energy consumption. Studies show that it is possible to reduce over 50% of the energy cost by implementing energy efficiency actions in lighting systems. According to PROCEL, the installed power with lighting in hypermarkets is greater than 100 kW in over 60% of the cases, thus representing an important type of building in the commercial sector. Additionally, studies show that the group efficiency of the lamp-ballast-luminary if often forgotten, yielding in inefficient lighting projects. The use of natural lighting integrated to the artificial lighting can offer not only potential to reduce energy consumption but also a more pleasant and healthy environment. This work describes a field study that was conducted in two different hypermarkets in the city of Campo Grande - MS in Brazil, with different artificial and natural lighting systems. The lighting system in hypermarket A consists of fluorescent T5 lamps in luminaries with reflexive components and no natural lighting openings while in hypermarket B, it consists of fluorescent T8 lamps in luminaries with no reflexive components and 12 openings for natural lighting. To evaluate and compare the energy efficiency of both lighting systems field research, energy consumption and lighting distribution measurements were carried out. The authors concluded that the use of natural lighting, associated with an efficient combination of lamp-luminary-ballast and automation systems offer great potential for energy efficiency

A significant problem in the automatic design of 3D graphics is the configuration of the lighting for a scene. The number of lights included, and the properties of these lights, has an enormous impact on what a viewer can judge about the content (the objects), properties (the geometric characteristics and spatial relations of the objects) and other aesthetic qualities of a scene. The traditional approach to lighting design for image synthesis is based on manual design methods, whereby users interactively specify values of lighting parameters, render the scene, and modify the lighting parameters until the desired visual properties of the scene are achieved. Non-expert users encounter a number of difficulties in selecting the appropriate lighting parameters, as the process requires both a subtle technical and aesthetic understanding of lighting in computer graphics. In this thesis, perceptual aspects such as contrast and the non-linear characteristics of our perceptual response to colour are combined with practical studio lighting techniques and a novel treatment of shadows, to yield an extension to existing perceptual approaches to lighting design. This so-called ideal lighting approach optimises the lighting configuration for a scene with respect to a set of absolute perceptual metrics. An intuitive approach to lighting design, lighting-by-example, is also proposed and extensively explored in forms that exploit both the perception-based lighting framework and a new wavelet formulation. User studies are conducted both to configure the perception-based lighting objective function and to evaluate the performance of the proposed lighting design approaches. Finally, we develop an interactive interface for the lighting design process that incorporates both the ideal lighting and lighting-by-example approaches.

We present an automated approach for high-quality preview of feature-film rendering during lighting design. Similar to previous work, we use a deep-framebuffer shaded on the GPU to achieve interactive performance. Our first contribution is to generate the deep-framebuffer and corresponding shaders automatically through data-flow analysis and compilation of the original scene. Cache compression reduces automatically-generated deep-framebuffers to reasonable size for complex production scenes and shaders. We also propose a new structure, the indirect framebuffer, that decouples shading samples from final pixels and allows a deep-framebuffer to handle antialiasing, motion blur and transparency efficiently. Progressive refinement enables fast feedback at coarser resolution. We demonstrate our approach in real-world production.

Examensarbetet är en undersökning avseende implementering av Human Centric Lighting (HCL)- system i hemmamiljö. En litteraturstudie har genomförts om HCL, dess effekter på människan och LED-belysningens påverkan både på människan och miljön. För att få en bra praktisk grund gjordes även ett undersökande besök på Lindeborgsskolan i Malmö som i ett pilotprojekt har installerat HCL-system i ett klassrum. HCL handlar bland annat om att anpassa ljuset till människans varierande behov genom att variera intensitet (Lux) och färgtemperatur (Kelvin). Belysning har stor betydelse för människans välmående där en belysning med onaturlig spektralfördelning och flimmer kan leda till stress, sömnproblem samt att ögonen kan försämras. Ett bra varierande ljus kan däremot öka människans välmående, produktivitet och även ge en positivare inställning. En del forskning visar även på att HCL kan minska risken för årstidsbunden depression. Ett blått, mer intensivt ljus har en uppiggande effekt medan ett rött nerdämpat ljus verkar lugnande. Genom att utsätta kroppen för mycket blått ljus på förmiddagen men inte på eftermiddagen/kvällen gynnas kroppens cirkadiska cykel. Även rött ljus har visat sig ha en uppiggande effekt men påverkar inte den cirkadiska cykeln och kan med fördel användas även på kvällstid om en högre ljusintensitet behövs. Tre separata reglerbara belysningssystem har undersökts: Clas Ohlson WiFi Smart Bulb, IKEA trådfri belysning och Philips Hue White Ambiance. Kravet som ställdes för att belysningen skulle tas med i testet var att den skulle finnas tillgänglig i en relativt vanlig butik. Belysningen har testats både med avseende på ljusegenskaper samt energianvändning. En del av mätningarna utfördes med ett Ulbrichtklot på Clas Ohlsons ljuslaboratorium där färgspektrum, lumenvärde samt mycket annan information om ljuskällan kunde tas fram, samt med en handhållen spektrometer för att se flimmeravgivningen ifrån lampan vid olika inställningar. Energianvändningen undersöktes beträffande förändringar vid variation av färgtemperatur, intensitet och även i de fall som separat reglerutrustning krävdes. De tre belysningssystemen visade sig ha olika fördelar och nackdelar där en till slut valdes ut för att installeras i ett sovrum i utbildningsprojektet Dalarnas Villa. Baserat på ett tidigare gjort ljusschema, i en masteruppsats gjord av en ljusdesigner vid KTH, togs ett nytt ljusschema fram för sovrummet som förändrar ljusets intensitet och färgtemperatur för att främja den cirkadiska cykeln. Då författarna ser att detta är ett viktigt ämne så har varje möjlighet till att visa upp det installerade systemet tagits. Vid samtal med bland annat energirådgivare från Dalarna så har ett stort intresse visats. ” Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity (WHO 1946). Health should be at the centre of all societal planning because social inequalities in health are costly to the society and counteract sustainable development (Malmö stad 2013). It is one of the main conditions for individual development opportunities through education, work, social relationships and participation in the society (UN 1949). Health is a key to the other human rights and also constitutes a separate right (WHO 2008).” Sustainability issues for SSL (R. Karlsson et al. 2016)
This thesis is a study concerning the implementation of Human Centric Lighting (HCL)-systems in the home environment. A literature study has been conducted on light, its effects on humans and the influence of LED lighting on both humans and the environment. To obtain a good practical foundation, an investigative study visit was also made to Lindeborgsskolan in Malmö, which as a pilot project has installed HCL systems in a classroom. HCL is, among other things, about adapting the light to man's varying needs by varying intensity (Lux) and color temperature (Kelvin). Lighting is of great importance to human well-being where lighting with unnatural spectral distribution and flicker can lead to stress, sleep problems and that the eyes can deteriorate. A good variety of light can, on the other hand, increase human well-being, productivity and give a positive attitude. Some research also shows that HCL can reduce the risk of seasonal depression. A blue, more intense light has a wakeup effect, while a red low intensity light feels soothing. By exposing the body to much blue light in the morning but not in the afternoon / evening, the body's circadian cycle benefits. Even red light has been shown to have a stimulating effect but does not affect the circadian cycle and can be used even in the evening if a higher light intensity is needed. Three separate controllable lighting systems have been investigated: “Clas Ohlson Wi-Fi Smart Bulb”, “IKEA trådfri” and “Philips Hue White Ambiance”. The lighting has been tested both in terms of light quality and energy use. The light quality was examined partly with an “Ulbrichtklot” at Clas Ohlson's light laboratory where color spectrum as well as various other information could be obtained, and with a hand-held spectrometer to see the flicker output from the lamp at different settings. The energy consumption was investigated regarding variation of color temperature, intensity and even in cases where separate control equipment was required. The three lighting systems were shown to have different advantages where eventually the Philips Hue Ambience White was selected to be installed in a bedroom in the project villa Dalarnas Villa. Based on a previous master thesis, a light schedule was developed that changes the intensity and color temperature of light to promote the circadian cycle. As the authors see this as an important topic, every opportunity to show the installed system has been taken. A great deal of interest has been shown during discussions including Dalarna´s energy advisers. ” Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity (WHO 1946).

Denna studie avser att undersöka hur ökad upplevd realism kan uppnås i Augmented Reality (AR) applikationer, genom ökad användarinteraktion med utvalda, virtuella ljusparametrar. Den teoretiska referensramen omfattas av övergripande teorier kopplade till AR men även mer djupgående forskning kring virtuell ljussättning och ljusparametrar. I en domän där automatiserade lösningar för virtuell ljussättning dominerar, ämnar denna studie påvisa bristerna med automatisk hantering av virtuellt ljus och istället motivera en lösning av semi-automatisk karaktär. Studien avser även att söka svaret på vilken utav utvalda ljusparametrar som haft störst inverkan i åtagandet att öka upplevd realism. Med Action Design Research (ADR) som huvudsaklig forskningsmetod, utvecklas ett grundläggande tillägg till en befintlig AR applikation i nära samarbete med företaget Neava. Applikationstillägget möjliggör manuell justering av det virtuella ljusets riktning, intensitet och färgtemperatur. Applikationstillägget testas sedan av befintliga användare under observation, därefter besvarar användaren en enkät grundad i testet, där jämförelse mellan befintlig applikation och applikationstillägg är temat. Insamlade observations- och enkätdata sätts i centrum för analys med avsikt att förklara relevanta fenomen och mönster, kopplade till upplevd realism. Studien finner att det utvecklade applikationstillägget i 90% av fallen genererar en ökad upplevd realism. Vidare finner studien att den virtuella ljusparameter som bidragit mest till ökad realism är ljusriktning, efterföljt av ljusintensitet och den minst bidragande visar sig vara färgtemperatur. De slutsatser som dras i studien formuleras och presenteras avslutningsvis i form av en oberoende lista designprinciper.
The purpose of this study is to examine how an improved level of experienced realism could be achieved in Augmented Reality (AR) applications, by allowing increased user interaction with a chosen set of virtual lighting parameters. The theoretical foundation of this thesis is both concerned with surveys and literature reviews of AR in general but also virtual lighting and lighting parameters to a significant extent. In contrast to the majority of previous research, where estimating and managing virtual lighting is done automatically, this study suggests that a semi-automatic approach might be better suited in delivering improved levels of experienced realism. Through the course of this thesis it is also intended to evaluate which of the chosen lighting parameters that has had the greatest impact in achieving improved experienced realism. Action Design Research (ADR) is applied as the core research methodology and in collaboration with the company Neava, an addon for an existing AR application is developed. This addon enables manual adjustments of virtual light direction, intensity and color temperature. The addon is tested by users of the existing application under observation, afterwards the testers answer a brief survey concerning the test, where a comparison between existing application and addon is made. Data gathered from both the observations and the surveys are then subjects of an analysis, where different phenomena and findings regarding improved experienced realism is the focus. The study finds that roughly 90% of the testers did indeed experience an improved level of realism, using the semi-automatic addon. Furthermore the study finds that the virtual lighting parameter most effective in achieving this is light direction, followed by light intensity and least effective in the effort is color temperature. The conclusions made of this study are finally presented in the form of a list of design principles.

This diploma work discusses the design of an automatic lighting for the home. Each access point in the rooms is designed to detect with two laser beams. Laser beams can be extended with PIR sensor and a mechanical switch. An access point can be, for example frames . By this is achieved that when entering the room the light is switched on and the light goes off when leaving. Automatic lighting controls consists of the central panel, the remote sensing and the detection frame. The control panel controls laser beams and lights. Remote control is used to switch on/off the light in the certain room. The detection frame is used to detect a person who enters or leaves the room.

This thesis addresses a multi-phase research and development project that spanned nearly four years, targeted at providing an ultra high-efficiency, user-friendly, and economic intelligent lighting solution for commercial facility applications, initially targeting underground parking specifically. The system would leverage the strengths of four key technologies: high brightness white Light Emitting Diodes (LEDs), wireless sensor and actuator networks, single board computers, and cloud computing. An introduction to these technologies and an overview of how they were combined to build an intelligent lighting solution is given, followed by an in-depth description of the design and implementation of one of the main subsystems – the Sensor Middleware System – residing on a single board computer. Newly-available LED luminaires (a.k.a. light fixtures) bring the combination of high efficiency, reliability, illumination quality, and long-lifetime to the lighting market. Emerging low-power – and recently low-cost – 802.15.4 wireless networks offer high controllability and responsiveness to deployed luminaires and sensors. The cost- associativity, low maintenance, and easy build-up of Internet Data Center “cloud” computing resources make data collection and remote management infrastructure for Building Automation Systems accessible to even small companies. Additionally, these resources can be much more appropriately sized and allocated, which reduces energy use. These technologies are combined to form an Intelligent Lighting System (ILS). Fitting well within the Internet of Things paradigm, this highly distributed messaging-based “system of systems” was designed to be reliable through loose coupling – spanning multiple network layers and messaging protocols. Its goal was to deliver significant energy savings over incumbent technologies, configurable and responsive lighting service behaviour, and improved experience for users within the facility (pedestrians and drivers) and those interacting with its web-based tools (building managers and ILS administrators). The ILS was partitioned into three main subsystems as follows. The installed Wireless Field Network (WFN) of luminaires and sensors provided coordinated scheduled and real-time output level adjustment (i.e. dimming), with the help of motion sensor triggers. The Monitoring and Configuration System (MCS) in the cloud provided remote data collection and a web-based monitoring and configuration Graphical User Interface application. Network hardware and Message-Oriented Middleware (MOM) were responsible for tying these subsystems together. The MOM layer that provided the message brokering, translating, envelope wrapping, and guaranteed delivery services between the WFN and MCS, as well as field supervisory and quality-of-service functions for the WFN, was called the Sensor Middleware System (SMS). It was hosted on a single board computer located at the facility.

In computer graphics, lighting designs attempt to achieve desired visual goals and assist viewers to appreciate the synthesized images better. As most existing automatic lighting designs are mainly for static targets, in this paper we present a novel automatic lighting method for motion data. We divide our lighting design into “global lighting” for scenes and “local lighting” for characters. For global lighting, we propose a viewpoint entropy algorithm to determine its lighting parameters according to the acting area of the motion data. Then we show that the best placement of each local light could be obtained by solving the corresponding optimization problem. Note that key frames can be identified by observations of root’s trajectory of motion data. Finally, by appropriate interpolations of lighting parameters of each key frame, the goal of the lighting design for motion data could be achieved. Several examples are given to demonstrate the effectiveness of the proposed method.

To solve the agricultural damages caused by the climate change, this study is developed to build an automatic supplementary lighting platform for plant factories. The platform mainly uses aluminum as materials. The lighting strategy will depend on the DPI. During the day, platform parked at the original position and uses quantum sensor to accumulate the daylight. At night, it moved to the supplementary lighting area and provides lighting to plants. The platform is operated in cooperation with a PLC control system, and uses RFID and limit switch as a local positioning system at plant factories. In supplementary lighting area, lifting system detects the height of plants to adjust the level of lampshade accordingly. The study operated 10 times movement experiments, after first 5 times calibration, the success rate of last 5 times moving positioning is 93%, and the success rate of 10 times lifting experiments is 98%. The platform can provide an average of 354 μmol /m2 /s light intensity within the distance of 10cm from the plants, and 3.27 μmol CO2 / m2 / s if it is within the photosynthesis characteristic of lettuce. Based on the results of two-week experiment, it can be confirmed that supplementary lighting is able to provide sufficient lighting to plants during the night, and reach DPI standard of each supplementary lighting area.

This thesis proposes to use a power factor correction (PFC) power supply for providing electric energy to street light LED (Light-Emitting Diode) modules, which can automatically determine the brightness and color in the surrounding in order to change the duty cycle of pulse width modulation (PWM) signals for a complementary LED luminance. For example, when it rains or fogs, street light LED modules will switch the light from cool-white to warm-white to increase the visibility. The system utilizes Arduino microcontroller to detect the data of the light sensor and then send the corresponding duty cycle of PWM signal to the dimming circuit. The voltage of LED modules is changed by controlling the feedback voltage of PFC IC. The If of LED increases due to diode property as the working voltage increases, hence the LED brightens; On the contrary, the LED darkens as the working voltage decreases. The aforementioned is how brightness is adjusted in this study. Besides, microcontroller detects the humidity and rain sensors based on the current weather conditions to adjust two different colors of street light and its brightness. To sum up, comparing this street light LED system (adjust by PWM voltage control) with the normal lighting system (adjust by PWM current control), it is found that the former yields better performance. The whole system reaches the total efficiency up to 87% and power factor up to about 0.93.

Through the optimization of light design, the 3D automatic measurement system will never stop until it achieves the efficiency of the gauging. This measurement system includes two kinds of system. First, optics servosystem: standardized system, turret type percentage, and zoom lens. Second, photo source servosystem: objective table, coaxial light, 4 split ring light, and colored photo source. Using QVPAK software from MITUTOYO Corporation, each measurement routine of the testing workpiece needs to be established in advance, and coordinates with the migration position of the 3D platform, then, transforms into the Visual Basic program. The system can automatically gauge a huge amount of the processed workpiece size. This experiment confirmed that the system gauging time is short, may avoid the personal error, and the accuracy may reach 0.002mm. Therefore, this research uses the Taguchi Method and fuzzy logic, develops a multiple quality characteristic calculating method which processes fuzziness project. This experiment designated the optimization design of the coaxial light and 4 split ring light for the improvement sign.

An automatic assembly system with eye-in-hand visual servoing is proposed in the thesis. Real-time vision is employed to assist a robotic manipulator to perform assembly tasks for 3C products. In order to accomplish hand-eye coordination tasks using a robotic manipulator with stereo vision, either an offline or online hand-eye calibration procedure should be performed to determine the coordinate transformation between the robotic manipulator and the vision system. In this thesis, offline hand-eye calibration approaches are employed for eye-in-hand configurations. Since precision control task is required, an eye-in-hand configuration is employed. The system is implemented in two ways, with and without structured lighting mounted on the end-effector of a 6-DOF robotic manipulator. Firstly, object features are extracted with the stereo vision system. Then, positions and orientations of objects are reconstructed by performing image processing techniques. Finally, the assembly task is encoded to hold the back shell and precisely position it onto the cellular phone to accomplish the automatic assembly task with precision.

At night, the lighting luminaire will provide low color temperature environment for the best state of the melatonin secreting. The luminous output would dim gradually when one going to bed until lighting off. Before getting up in the morning, the luminous output would increase up gradually and simulate daylight environment by changing the color temperature of the luminaire according to the sunlight in order to maintain the human body to be in the normal and wealthy biological status. The lighting scheme may be applied to the residential lighting luminaire design, especially in the table light luminaire. Compared with the different design of commercial products, the lighting luminaire proposed has advantages of adjusting linearly and automatically in color temperature, control the color temperature according to the time, low cost and so on. It is included, in this design, deducing a light mixing system according to the relation of the color temperature and color coordinate of the LED light sources. The system could ensure the current ratio relationship between two different color temperature illuminants and the color temperature of the mixed light.
