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 Synopsis A Framework for Realtime 3-D Reconstruction by Space Carving Using Graphics Hardware by : Christian Nitschke

This book was released on 2007-03-05 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: Reconstruction of real-world scenes from a set of multiple images is a topic in Computer Vision and 3D Computer Graphics with many interesting applications. There is a relation to Augmented and Mixed Reality (AR/MR), Computer-Supported Collaborative Work (CSCW), Computer-Aided industrial/architectural Design (CAD), modeling of the real-world (e.g. computer games, scenes/effects in movies), entertainment (e.g. 3D TV/Video) and recognition/analyzing of real-world characteristics by computer systems and robots. There exists a powerful algorithm theory for shape reconstruction from arbitrary viewpoints, called shape from photo-consistency. However, it is computationally expensive and hence can not be used with applications in the field of 3D video or CSCW as well as interactive 3D model creation. Attempts have been made to achieve real-time framerates using PC cluster systems. While these provide enough performance they are also expensive and less flexible. Approaches that use GPU hardware-acceleration on single workstations achieve interactive framerates for novel-view synthesis, but do not provide an explicit volumetric representation of the whole scene. The proposed approach shows the efforts in developing a GPU hardware-accelerated framework for obtaining the volumetric photo hull of a dynamic 3D scene as seen from multiple calibrated cameras. High performance is achieved by employing a shape from silhouette technique in advance to obtain a tight initial volume for shape from photo-consistency. Also several speed-up techniques are presented to increase efficiency. Since the entire processing is done on a single PC, the framework can be applied to mobile setups, enabling a wide range of further applications. The approach is explained using programmable vertex and fragment processors and compared to highly optimized CPU implementations. It is shown that the new approach can outperform the latter by more than one magnitude. The thesis is organized as follows: Chapter 1 contains an introduction, giving an overview with classification of related techniques, statement of the main problem, novelty of the proposed approach and its fields of application. Chapter 2 surveys related work in the area of dynamic scene reconstruction by shape from silhouette and shape from photo-consistency. The focus lies on high performance reconstruction and hardware-acceleration. Chapter 3 introduces the theoretical basis for the proposed [...]

Book Synopsis 3D Reconstruction from Multiple Images by : Theo Moons
Download or read book 3D Reconstruction from Multiple Images written by Theo Moons and published by Now Publishers Inc. This book was released on 2009-10-23 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue discusses methods to extract 3-dimensional (3D) models from plain images. In particular, the 3D information is obtained from images for which the camera parameters are unknown. The principles underlying such uncalibrated structure-from-motion methods are outlined. First, a short review of 3D acquisition technologies puts such methods in a wider context, and highlights their important advantages. Then, the actual theory behind this line of research is given. The authors have tried to keep the text maximally self-contained, therefore also avoiding to rely on an extensive knowledge of the projective concepts that usually appear in texts about self-calibration 3D methods. Rather, mathematical explanations that are more amenable to intuition are given. The explanation of the theory includes the stratification of reconstructions obtained from image pairs as well as metric reconstruction on the basis of more than 2 images combined with some additional knowledge about the cameras used. Readers who want to obtain more practical information about how to implement such uncalibrated structure-from-motion pipelines may be interested in two more Foundations and Trends issues written by the same authors. Together with this issue they can be read as a single tutorial on the subject.

Book Synopsis Perspectives in Shape Analysis by : Michael Breuß
Download or read book Perspectives in Shape Analysis written by Michael Breuß and published by Springer. This book was released on 2016-09-30 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent advances in the field of shape analysis. Written by experts in the fields of continuous-scale shape analysis, discrete shape analysis and sparsity, and numerical computing who hail from different communities, it provides a unique view of the topic from a broad range of perspectives. Over the last decade, it has become increasingly affordable to digitize shape information at high resolution. Yet analyzing and processing this data remains challenging because of the large amount of data involved, and because modern applications such as human-computer interaction require real-time processing. Meeting these challenges requires interdisciplinary approaches that combine concepts from a variety of research areas, including numerical computing, differential geometry, deformable shape modeling, sparse data representation, and machine learning. On the algorithmic side, many shape analysis tasks are modeled using partial differential equations, which can be solved using tools from the field of numerical computing. The fields of differential geometry and deformable shape modeling have recently begun to influence shape analysis methods. Furthermore, tools from the field of sparse representations, which aim to describe input data using a compressible representation with respect to a set of carefully selected basic elements, have the potential to significantly reduce the amount of data that needs to be processed in shape analysis tasks. The related field of machine learning offers similar potential. The goal of the Dagstuhl Seminar on New Perspectives in Shape Analysis held in February 2014 was to address these challenges with the help of the latest tools related to geometric, algorithmic and numerical concepts and to bring together researchers at the forefront of shape analysis who can work together to identify open problems and novel solutions. The book resulting from this seminar will appeal to researchers in the field of shape analysis, image and vision, from those who want to become more familiar with the field, to experts interested in learning about the latest advances.
