Повний текст джерелаOne might wonder what can be gained from the image-laser fusion and in which measure such a hybrid system can generate automatically complete and photorealist 3D models of difficult to access and unstructured underground environments. In such environments, special attention must be given to the main issue standing behind the automation of the 3D modeling pipeline whic is represented by the capacity to match reliably image and laser data in GPS-denied and feature-less areas. In addition, time and in-situ access constraints require fast and automatic procedures for in-situ data acquisition, processing and interpretation in order to allow for in situ verification of the 3D scene model completeness. Finally, the currently generated 3D model represents the only available information providing situational awareness based on which autonomous behavior must be build in order to enable the system to act intelligently onthe- fly and explore the environment for ensuring the 3D scene model completeness. This dissertation evaluates the potential of a hybrid image-laser system for generating in-situ complete and photorealist 3D models of challenging environments, without requiring human operator intervention. The presented research focuses on two main aspects: (i) the automation of the 30 modeling pipeline, targeting the automatic data matching in feature-less and GPS-denied areas for in situ world modeling and (ii) the exploitation of the generated 3D models along with visual servoing procedures to provide mobile systems with autonomous site digitization and exploration capabilities. We design a complementary and cooperative image-laser fusion which lead to a 4D mosaicing sensor prototype

Повний текст джерелаCoherent lensless imaging techniques can break the limitations associated with conventional microscopy techniques. The configuration of coherent diffraction imaging makes it possible to image isolated non-crystalline objects with spatial resolutions limited, in principle, only by the illuminated wavelength (i.e. a few tens of nanometers to a few angstroms in the XUV and X domains, respectively). In this thesis, we develop and improve, experimentally and numerically, 2D and 3D lensless imaging techniques, for nanometric resolutions in a femtosecond single shot. Responding to the limitations of these techniques to aberrations and partial coherence, here, improvements of wavefront and spatial-coherence correction in holographic techniques are proposed. Indeed, the exploitation of the source properties makes possible to optimise the reconstruction from diffraction patterns or holograms in order to obtain the most faithful image possible in a single femtosecond flash. By exploiting machine vision concepts, this thesis also shows the possibility of accessing 3D information in single shots, extracted from two coherent X-ray diffraction patterns, taken simultaneously from two stereo angles. This opens the way towards the exploration of matter on nanometric volumes (voxels) solved at unmatched temporal resolutions

Повний текст джерелаThis thesis presents work results about an optical laser diode range finder for short distance measurements in robotics, and possibility of application in 3D vision. Its principle lies on an amplitude modulation of the optical beam, and a direct detection of the distance by measuring the phase shift corresponding to the propagation time of the modulated beam. This research presents :- the description of the laser range finder used, with its theoritical and practical performances. - the interest of a simulation of the functioning for an application in robotics. - the detailed characterization of the detected signal and its perturbations, for this simulation. - the results of the simulations. - experimental profile records realized with this laser range finder

Повний текст джерелаThis research work regards the scientific challenge of reconstructing the ground and the object presents under a vegetation cover from airborne observations. Airborne laser scanning is a promising technology. Full-waveform devices are able to record the complete temporal return signal following the emission of a short laser pulse towards the ground. This offers a great potential for remote sensing of forested areas, since the laser pulse will travel through the vegetation. Many commercial systems are already operated for topography or bathymetry. Scientists have been using these systems for vegetation observation, even if they are not dedicated to this purpose. The objective of this thesis is to study the relevance of full-waveform lidars for the geometric reconstruction of digital terrain models (DTM) under vegetation. We also aim at developing simulation and data processing toolsthat will help design and optimize future sensors dedicated to vegetation observation. Our first task was the development of a new physical simulator for full-waveform lidar measurement. The DELiS model (n-Dimensional Estimation of Lidar Signals) is able tosimulate the observation of complex and realistic vegetation scenes while accounting for atmosphere and sun perturbations, and simulating the multiple scattering of the laser pulse in the canopy. We have also implemented a sensor model for simulation of the measurement, amplification and digitization noises. This operational simulation tool is a key asset for future physical studies as well as for designing and optimizing future sensors and data processing methods. After validating the DELiS model by confrontation with analytical results, we have used it for studying the interest of full-waveform lidar for digital terrain models reconstruction under vegetation. For this purpose, we have developed a full-waveform lidar data processing method for decomposition of the signals and classification of the lidar echoes into two classes : ’ground’ and ’vegetation’. We were then able to reconstruct ground geometry.Finally, we have led a study on the combination of multi-angular acquisitions for improvement of the reconstructions.Our work shows that airborne full-waveform lidar observations may allow ground reconstruction with sub-metric resolutions and a precision of 10 to 20 centimeters in forested areas. Combining multiple viewing angles provides additional data, and helps improving the precision of the reconstructions. Yet, we show that non-nadir viewing is much more sensitive to trunks and branches. These elements may be the cause of an additional error in the classification and reconstruction processes. For this reason, we recommend using nadir viewing for single-view ground reconstruction, and propose a method for optimally selecting non-nadir views for the detailed observation of restricted areas of interest

Повний текст джерелаLaser thermal ablation is a minimally invasive therapy that consists in transcutaneously inserting one or more laser probes into pathological tissue (e.g., a tumor), and using the absorption of light energy by the tissue to generate localized heating and induce coagulation necrosis (destruction of diseased cells, from 43 to 100°C) or moderate hyperthermia (stimulation of an immune response or activation of a heat-sensitive drug, from 40 to 43°C). In order to precisely control the therapeutic procedure, it is preferable to be able to spatially map heat deposition in the targeted tissue in real time. This can be achieved by using advanced MRI thermometry methods to image tissue temperature distribution in real time and volume (75 ms per acquisition), with a spatial resolution of around one millimeter and an uncertainty of around 1°C.This thesis presents a set of technological developments enabling precise control of heating in targeted tissue. A first study shows the feasibility of exploiting MRI thermometry to automatically adjust the power emitted by a laser in real time, in order to temporally force the maximum temperature of tissue located near the laser probe to follow a predefined temperature set point, using a proportional-integral-derivative control algorithm. The method has been validated on muscle in a preclinical model. A second study presents a more sophisticated automated temperature control method for simultaneously controlling the light energy emitted by several laser probes. The method has also been validated in vivo on a realistic preclinical model.In parallel with this work, a prototype of an innovative laser probe consisting of several laser emitters was developed and evaluated in vivo to demonstrate the possibility of performing conformal ablations with a single probe. Software developments were also carried out to facilitate the design and testing of the methods presented in the first two studies.This thesis has developed innovative methods for improving the safety and accuracy of MRI thermometry-guided laser ablation procedures. The feedback algorithms are adaptable to other ablation devices commonly used in interventional radiology (radiofrequency, focused ultrasound, microwave)
