Abstract

Mobile robot motion planning in unstructured dynamic environments is a challenging task. Thus, often suboptimal methods are employed which perform global path planning and local obstacle avoidance separately. This work introduces a holistic planning algorithm which is based on the concept of state

Abstract

Dans le domaine de la construction, il est important de pouvoir capturer la réalité de manière complète et précise. Avec le scanning laser, la photogrammétrie est la technologie la plus employée à cet effet. Elle vise à recréer un objet sous forme de nuage de point depuis des images prise autour de celui-ci. Cependant, les meilleures pratiques pour effectuer un relevé photogrammétrique sont parfois floues; et évaluer leurs impacts peut s'avérer laborieux. &#13;&#13;En effet, un nombre importants de facteurs viennent influencer la qualité finale d'une reconstruction, autant en termes de paramètres inhérents à l'appareil photo qu'en termes de positionnement et orientation des photos. L'utilisation de drones décuple encore ce phénomène en augmentant le nombre de positions et d'orientations de la caméra possibles. La campagne de relevé devient un processus long et la bonne qualité de la reconstruction finale n'est jamais assurée. &#13;&#13;Dans ce contexte, ce travail propose une méthode complètement virtuelle et automatisée permettant la comparaison de la qualité de reconstructions photogrammétriques en recréant une campagne de relevé directement dans le logiciel de photogrammétrie Metashape. La qualité s'entend en termes de fidélité géométrique, confiance et exhaustivité de la reconstruction. Elle permet de traiter chaque paramètre individuellement et évalue son impact de manière automatique et rapide. Le processus est ici illustré pour les conséquences de la prise d'image sur la qualité finale du relevé. &#13;&#13;Elle permet par exemple de mettre en évidence qu'une prise d'image circulaire est suffisante pour les relevés basse résolution d'objets relativement simples. Si une plus haute résolution est requise ou que l'objet à capturer est plus élaboré, il est alors préférable d'utiliser un planificateur de vol tridimensionnel. Les relevés nadir ne sont jamais à même de retranscrire correctement la géométrie de l'objet. &#13;&#13;Le processus, ici appliqué à la position et l'orientation des images, s'inscrit dans un contexte plus grand en fournissant une méthode innovante pour tester l'influence des paramètres utilisés sur un processus de reconstruction photogrammétrique. In the field of construction, it is important to be able to capture reality completely and accurately. Along with laser scanning, photogrammetry is the most used technology for this purpose. It aims to recreate an object as a point cloud from images taken around it. However, the best practises in photogrammetry are sometimes blurred, and evaluating their impact can be laborious. &#13;&#13;Indeed, a lot of important factors influence the final quality of a reconstruction, as much in terms of parameters inherent to the camera as in terms of positioning and orientation of the pictures. The use of drones increases this phenomenon by increasing the number of possible positions and orientations. The survey campaign becomes a long process and the good quality of the final reconstruction is never assured. &#13;&#13;Facing this issue, this work proposes a completely virtual and automated method of comparison of photogrammetric reconstruction by recreating a survey campaign directly in the photogrammetry software Metashape. It allows to treat each parameter individually and to evaluate its impact in an automatic and fast way. The process is illustrated here on the consequences of the image capture scenario on the final quality of the survey. &#13;&#13;It shows that a circular image capture is sufficient for low resolution surveys of relatively simple objects. If a higher resolution is required or if the object to be captured is more elaborate, it is then preferable to use a three-dimensional flight planner. Nadir surveys are never able to correctly capture the geometry of the object. &#13;&#13;The process, applied here to the position and orientation of images, is part of a larger context by providing a new method to test the influence of the parameters of a photogrammetric reconstruction process.

Abstract

Ordinary differential equations (ODEs) and differential-algebraic equations (DAEs) are widely used to model control systems in engineering, natural sciences, and economy. Optimal control plays a central role in optimizing such systems and to operate them effi ciently and safely. The intention of this textbook is to provide both, the theoretical and computational tools that are necessary to investigate and to solve optimal control problems with ODEs and DAEs. An emphasis is placed on the interplay between the optimal control problem, which typically is defi ned and analyzed in a Banach space setting, and discretizations thereof, which lead to finite dimensional optimization problems. The theoretical parts of the book require some knowledge of functional analysis, the numerically oriented parts require knowledge from linear algebra and numerical analysis. Practical examples are provided throughout the book for illustration purposes. The book addresses primarily master and PhD students as well as researchers in applied mathematics, but also engineers or scientists with a good background in mathematics. The book serves as a reference in research and teaching and hopefully helps to advance the state-of-the-art in optimal control.

Abstract

The Cooperative Control of Multiagent Systems course will illustrate the various attributes needed in such systems and the complexity inherent to the design. Cooperative systems are currently limited in capacity and in availability, partly due to this so-called complexity and to the multifaceted nature of design and analysis. This course will focus on the well-known problem of multiagent path planning, with brief discussions of advanced techniques for formation flight health management. The optimization problem and its solution will be cast in the framework of dynamic programming and Markov decision processes, typical of problems of optimization under uncertainty. A discussion of the results of numerical simulations, integrating decision-making with closed-loop dynamics of the air vehicles, for both formation flight and path planning, will conclude the course.

Abstract

Miniaturization of electronic devices and recent developments in wireless communication technology are leading to the creation of a range of personal information appliances, or biotic sensors, which can be attached to or implanted in human bodies. The wireless networking of such devices is known as the wireless body area network (BAN). BAN can share information effectively and securely, reduce functional redundancies, and allow new conveniences and services. Moreover, it provides new possibilities for high-quality service from hospitals, by linking various biotic sensors to establish a body-area network of personal health information. In Body Area Communications: Channel Modeling, Communication Systems, and EMC, Wang and Wang provide a systematic introduction to body area networks leading readers from an introductory level to in-depth and more advanced topics. . Provides a concise introduction to this emerging topic based on classroom-tested materials. Details the latest IEEE 802.15.6 standard activities. Moves from very basic physics, to useful mathematic models, and then to practical considerations. Covers not only EM physics and communications, but also biological applications. Topics approached include: link budget, bit error rate performance, RAKE and diversity reception; SAR analysis for human safety evaluation; and modeling of electromagnetic interference to implanted cardiac pacemakers . Provides Matlab and Fortran programs for download from the Companion WebsiteThis book is ideal for graduate students, engineers and researchers interested in body area networks, or those who would like to apply expertise in signal processing, application development and implementation, IC design, instrumentation, software framework, hardware/software optimization, distributed processing, and communications to BAN applications. Researchers and practicing engineers in biomedical engineering, who are interested in extending techniques to the wireless communications space, will also find this book to be a helpful reference.
