Download or read book Advances in Photometric 3D Reconstruction written by Jean-Denis Durou and published by Springer Nature. This book was released on 2020-09-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest advances in photometric 3D reconstruction. It provides the reader with an overview of the state of the art in the field, and of the latest research into both the theoretical foundations of photometric 3D reconstruction and its practical application in several fields (including security, medicine, cultural heritage and archiving, and engineering). These techniques play a crucial role within such emerging technologies as 3D printing, since they permit the direct conversion of an image into a solid object. The book covers both theoretical analysis and real-world applications, highlighting the importance of deepening interdisciplinary skills, and as such will be of interest to both academic researchers and practitioners from the computer vision and mathematical 3D modeling communities, as well as engineers involved in 3D printing. No prior background is required beyond a general knowledge of classical computer vision models, numerical methods for optimization, and partial differential equations.

Available in PDF, EPUB and Kindle. Book excerpt: Die Rekonstruktion von 3D-Gestaltinformationen ist eine fundamentale Aufgabenstellung im Bereich Computer-Vision. Unter den verschiedenen Techniken ist das sogenannte Photometrische Stereo Verfahren (PS) hervorzuheben, da es im Vergleich zu anderen Ansätzen ein höheres Potenzial für eine hoch genaue 3D-Rekonstruktion besitzt. Diese Arbeit befasst sich mit Verallgemeinerungen klassischer PS-Ansätze, die dieses Potenzial weiter ausschöpfen sollen. Die Entwicklungen können beispielsweise verwendet werden, um in Zukunft die 3D-Information in verschiedensten Bereichen für einen Anwender zu erschließen, wie etwa in der Medizin, der Film- und Videospieleindustrie, beim autonomen Fahren oder für Anwendungen in der virtuellen Realität. Die erste der Neuentwicklungen betrifft die systematische Verwendung von hellen Lichtreflexionen in der Berechnung der 3D-Rekonstruktion sowie die perspektivische Projektion. Hierdurch werden Beschränkungen üblicher Methoden, wie auf die Rekonstruktion diffus reflektierender Materialien und auf relativ weit entfernte Objekte, aufgehoben. Die Anwendbarkeit des entwickelten Ansatzes wird mittels der Rekonstruktion aus endoskopischen Bildern mit vielen hellen Lichtreflexionen untermauert. In einem weiteren Schritt wird gezeigt, wie man in Echtzeit eine 3D-Rekonstruktion auch von sehr feinen Details mittels eines verallgemeinerten Reflexionsmodells erreichen kann. Hierdurch werden hochaufgelöste Rekonstruktionen auch von Details erreicht, die für das menschliche Auge in Bildern unsichtbar sind. Hieraus ergeben sich viele potenzielle Anwendungsmöglichkeiten, etwa im Bereich der automatischen Detektion von Mikrodruck, die im Sicherheitsbereich Verwendung finden, oder in der industriellen Produktion für die Detektion sehr feiner Strukturen wie etwa gedruckter Schaltkreise. Als weiterer Beitrag der Arbeit wird ein Verfahren für das sogenannte nicht-kalibrierte PS entwickelt, bei dem neuronale Netzwerke verwendet werden, um die in diesem Fall fehlende Information der Beleuchtungsrichtung auszugleichen. Schließlich wird zum ersten Mal in der Literatur beschrieben, wie man basierend auf Metaheuristiken und tiefen neuronalen Netzen eine qualitativ hochwertige 3D-Rekonstruktion allein durch Bilder aus dem Internet oder natürliche Bilder ohne weiteres zusätzliches Wissen erlangt.zeige weniger.

Book excerpt: Zusammenfassung: This book offers a comprehensive and unbiased introduction to 3D Computer Vision, ranging from its foundations and essential principles to advanced methodologies and technologies. Divided into 11 chapters, it covers the main workflow of 3D computer vision as follows: camera imaging and calibration models; various modes and means of 3D image acquisition; binocular, trinocular and multi-ocular stereo vision matching techniques; monocular single-image and multi-image scene restoration methods; point cloud data processing and modeling; simultaneous location and mapping; generalized image and scene matching; and understanding spatial-temporal behavior. Each topic is addressed in a uniform manner: the dedicated chapter first covers the essential concepts and basic principles before presenting a selection of typical, specific methods and practical techniques. In turn, it introduces readers to the most important recent developments, especially in the last three years. This approach allows them to quickly familiarize themselves with the subject, implement the techniques discussed, and design or improve their own methods for specific applications. The book can be used as a textbook for graduate courses in computer science, computer engineering, electrical engineering, data science, and related subjects. It also offers a valuable reference guide for researchers and practitioners alike

Download or read book Multi view Stereo written by Yasutaka Furukawa and published by . This book was released on 2015 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This tutorial presents a hands-on view of the field of multi-view stereo with a focus on practical algorithms. Multi-view stereo algorithms are able to construct highly detailed 3D models from images alone. They take a possibly very large set of images and construct a 3D plausible geometry that explains the images under some reasonable assumptions, the most important being scene rigidity. The tutorial frames the multiview stereo problem as an image/geometry consistency optimization problem. It describes in detail its main two ingredients: robust implementations of photometric consistency measures, and efficient optimization algorithms. It then presents how these main ingredients are used by some of the most successful algorithms, applied into real applications, and deployed as products in the industry. Finally it describes more advanced approaches exploiting domain-specific knowledge such as structural priors, and gives an overview of the remaining challenges and future research directions.

Download or read book An Introduction to 3D Computer Vision Techniques and Algorithms written by Boguslaw Cyganek and published by John Wiley & Sons. This book was released on 2011-08-10 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer vision encompasses the construction of integrated vision systems and the application of vision to problems of real-world importance. The process of creating 3D models is still rather difficult, requiring mechanical measurement of the camera positions or manual alignment of partial 3D views of a scene. However using algorithms, it is possible to take a collection of stereo-pair images of a scene and then automatically produce a photo-realistic, geometrically accurate digital 3D model. This book provides a comprehensive introduction to the methods, theories and algorithms of 3D computer vision. Almost every theoretical issue is underpinned with practical implementation or a working algorithm using pseudo-code and complete code written in C++ and MatLab®. There is the additional clarification of an accompanying website with downloadable software, case studies and exercises. Organised in three parts, Cyganek and Siebert give a brief history of vision research, and subsequently: present basic low-level image processing operations for image matching, including a separate chapter on image matching algorithms; explain scale-space vision, as well as space reconstruction and multiview integration; demonstrate a variety of practical applications for 3D surface imaging and analysis; provide concise appendices on topics such as the basics of projective geometry and tensor calculus for image processing, distortion and noise in images plus image warping procedures. An Introduction to 3D Computer Vision Algorithms and Techniques is a valuable reference for practitioners and programmers working in 3D computer vision, image processing and analysis as well as computer visualisation. It would also be of interest to advanced students and researchers in the fields of engineering, computer science, clinical photography, robotics, graphics and mathematics.

Available in PDF, EPUB and Kindle. Book excerpt: This volume collects the papers accepted for presentation at the 12th Int- national Conference on “Advanced Concepts for Intelligent Vision Systems” (ACIVS 2010). Following the ?rst meeting in Baden-Baden (Germany) in 1999, whichwaspartofalargemulticonference,theACIVSconferencethendeveloped into an independent scienti?c event and has ever since maintained the tradition of being a single track conference. ACIVS 2010 attracted computer scientists from 29 di?erent countries, mostly from Europe, Australia, and the USA, but also from Asia. Although ACIVS is a conference on all areas of image and video processing, submissions tend to gather within certain major ?elds of interest. This year 3D and depth processing and computer vision and surveillance were popular topics. Noteworthy are the growing number of papers related to theoretical devel- ments. We would like to thank the invited speakers Mubarak Shah (University of Central Florida), Richard Kleihorst (VITO, Belgium), Richard Hartley (A- tralian National University), and David Suter (Adelaide University) for their valuable contributions.

Book excerpt: It is with great pleasure that we present the proceedings of the 6th Inter- tional, Symposium on Visual Computing (ISVC 2010), which was held in Las Vegas, Nevada. ISVC provides a common umbrella for the four main areas of visual computing including vision, graphics, visualization, and virtual reality. The goal is to provide a forum for researchers, scientists, engineers, and pr- titioners throughout the world to present their latest research ?ndings, ideas, developments, and applications in the broader area of visual computing. This year, the program consisted of 14 oral sessions, one poster session, 7 special tracks, and 6 keynote presentations. The response to the call for papers was very good; we received over 300 submissions for the main symposium from which we accepted 93 papers for oral presentation and 73 papers for poster p- sentation. Special track papers were solicited separately through the Organizing and Program Committees of each track. A total of 44 papers were accepted for oral presentation and 6 papers for poster presentation in the special tracks.
