Available in PDF, EPUB and Kindle. Book excerpt: Arobotmustperceivethethree-dimensionalworldifitistobeeffective there. Yet recovering 3-D information from projected images is difficult, and still remains thesubjectofbasic research. Alternatively, onecan use sensorsthatcanprovidethree-dimensionalrangeinformationdirectly. The technique ofprojecting light-stripesstartedto be used in industrialobject recognition systems asearly asthe 1970s, andtime-of-flight laser-scanning range finders became available for outdoor mobile robotnavigation in the mid-eighties. Once range data are obtained, a vision system must still describe the scene in terms of 3-D primitives such as edges, surfaces, and volumes, and recognize objeCts of interest. Today, the art of sensing, extractingfeatures, and recognizing objectsbymeans ofthree-dimensional rangedataisoneofthemostexcitingresearchareasincomputervision. Three-Dimensional Machine Vision is a collection of papers dealing withthree-dimensionalrangedata. Theauthorsarepioneeringresearchers: some are founders and others are bringingnew excitements in thefield. I have tried to select milestone papers, and my goalhas beento make this bookareferenceworkforresearchersinthree-dimensionalvision. The book is organized into four parts: 3-D Sensors, 3-D Feature Extractions, ObjectRecognitionAlgorithms, andSystemsandApplications. Part I includes four papers which describe the development of unique, capable 3-D range sensors, as well as discussions of optical, geometrical, electronic, and computational issues.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: A stereo vision system was developed for the NaviGator, an autonomous vehicle designed for off-road navigation at the Center for Intelligent Machines and Robotics (CIMAR). The sensor outputs traversability grids defined by the CIMAR Smart Sensor Architecture. Stereo vision systems which have been developed in the past and previous research at CIMAR were examined. Hardware chosen for the system includes auto-iris lenses for improved outdoor performance, s-video cameras and a four frame grabber PCI card for digitizing the analog s-video signal. Software from SRI International was used for image rectification and the calculation of camera calibration parameters. The SRI stereo vision library was then used for 3D data calculation. With the 3D data, a least squares plane fitting algorithm was used to find the slope of the terrain in each traversability grid cell. This information was used to give the cell a traversability rating. Tests were performed to find the best image subsampling method and image processing resolution as well as the benefit of multiscale processing. Tests were also performed to find the optimal set of stereo processing parameters. These parameters included pixel search range, horoptor offset, correlation window size, confidence threshold and uniqueness threshold.

Book Synopsis Machine Vision for Three-Dimensional Scenes by : Herbert Freeman
Download or read book Machine Vision for Three-Dimensional Scenes written by Herbert Freeman and published by Elsevier. This book was released on 2012-12-02 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machine Vision for Three-Dimensional Scenes contains the proceedings of the workshop "Machine Vision - Acquiring and Interpreting the 3D Scene" sponsored by the Center for Computer Aids for Industrial Productivity (CAIP) at Rutgers University and held in April 1989 in New Brunswick, New Jersey. The papers explore the applications of machine vision in image acquisition and 3D scene interpretation and cover topics such as segmentation of multi-sensor images; the placement of sensors to minimize occlusion; and the use of light striping to obtain range data. Comprised of 14 chapters, this book opens with a discussion on 3D object recognition and the problems that arise when dealing with large object databases, along with solutions to these problems. The reader is then introduced to the free-form surface matching problem and object recognition by constrained search. The following chapters address the problem of machine vision inspection, paying particular attention to the use of eye tracking to train a vision system; images of 3D scenes and the attendant problems of image understanding; the problem of object motion; and real-time range mapping. The final chapter assesses the relationship between the developing machine vision technology and the marketplace. This monograph will be of interest to practitioners in the fields of computer science and applied mathematics.
Book Synopsis DEVELOPMENT OF A STEREO VISION SYSTEM FOR AN INDUSTRIAL ROBOT. by :
Download or read book DEVELOPMENT OF A STEREO VISION SYSTEM FOR AN INDUSTRIAL ROBOT. written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this thesis is to develop a stereo vision system to locate and classify objects moving on a conveyor belt. The vision system determines the locations of the objects with respect to a world coordinate system and class of the objects. In order to estimate the locations of the objects, two cameras placed at different locations are used. Image processing algorithms are employed to extract some features of the objects. These features are fed to stereo matching and classifier algorithms. The results of stereo matching algorithm are combined with the calibration parameters of the cameras to determine the object locations. Pattern classification techniques (Bayes and Nearest Neighbor classifiers) are used to classify the objects. The linear velocity of the objects is determined by using an encoder mounted to the shaft of the motor driving the conveyor belt. A robot can plan a sequence of motion to pick the object from the conveyor belt by using the output of the proposed system.
Book Synopsis A Few Steps Towards 3D Active Vision by : Thierry Vieville
Download or read book A Few Steps Towards 3D Active Vision written by Thierry Vieville and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: T. Viéville: A Few Steps Towards 3D Active Vision appears as Vol. 33 in the Springer Series in Information Sciences. A specific problem in the field of active vision is analyzed, namely how suitable is it to explicitly use 3D visual cues in a reactive visual task? The author has collected a set of studies on this subject and has used these experimental and theoretical developments to propose a synthetic view on the problem, completed by some specific experiments. With this book scientists and graduate students will have a complete set of methods, algorithms, and experiments to introduce 3D visual cues in active visual perception mechanisms, e.g. autocalibration of visual sensors on robotic heads and mobile robots. Analogies with biological visual systems provide an easy introduction to this subject.
Book Synopsis Single-Shot 3D Sensing Close to Physical Limits and Information Limits by : Florian Willomitzer

This book was released on 2019-07-05 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis discusses the physical and information theoretical limits of optical 3D metrology, and, based on these principal considerations, introduces a novel single-shot 3D video camera that works close to these limits. There are serious obstacles for a “perfect” 3D-camera: The author explains that it is impossible to achieve a data density better than one third of the available video pixels. Available single-shot 3D cameras yet display much lower data density, because there is one more obstacle: The object surface must be “encoded” in a non-ambiguous way, commonly by projecting sophisticated patterns. However, encoding devours space-bandwidth and reduces the output data density. The dissertation explains how this profound dilemma of 3D metrology can be solved, exploiting just two synchronized video cameras and a static projection pattern. The introduced single-shot 3D video camera, designed for macroscopic live scenes, displays an unprecedented quality and density of the 3D point cloud. The lateral resolution and depth precision are limited only by physics. Like a hologram, each movie-frame encompasses the full 3D information about the object surface and the observation perspective can be varied while watching the 3D movie.
Book Synopsis Three-dimensional Stereo Reconstruction and Sensor Registration with Application to the Development of a Multi-sensor Database by : William F. Oberle
Download or read book Three-dimensional Stereo Reconstruction and Sensor Registration with Application to the Development of a Multi-sensor Database written by William F. Oberle and published by . This book was released on 2002 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses efforts undertaken at the U.S. Army Research Laboratory (ARL), which support research in robotic perception. The efforts include collaborative work with the National Institute of Standards and Technology to develop a multi-sensor (laser radar LADAR, navigation and stereoscopic video (stereo) database with ground truth for use by the robotics research community. ARL's efforts are focused on stereo. The report documents procedures for determining the transformations between the cameras of the stereo system and the transformations between the camera system and other sensor, vehicle, and world coordinate systems. Results indicate that the measured stereo and ladar data are susceptible to large errors that affect the accuracy of the calculated transformations.
