Download or read book Self Calibration of Multi Camera Systems written by Ferid Bajramovic and published by Logos Verlag Berlin GmbH. This book was released on 2010 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-camera systems play an increasingly important role in computer vision. They enable applications like 3D video reconstruction, motion capture, smart homes, wide area surveillance, etc. Most of these require or benefit from a calibration of the multi-camera system. This book presents a novel approach for automatically estimating that calibration. In contrast to established methods, it neither requires a calibration object nor any user interaction. From a theoretical point of view, this book also presents and solves the novel graph theoretical problem of finding shortest triangle paths.

Download or read book Calibration and Orientation of Cameras in Computer Vision written by Armin Gruen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was conceived during the Workshop "Calibration and Orientation of Cameras in Computer Vision" at the XVIIth Congress of the ISPRS (In ternational Society of Photogrammetry and Remote Sensing), in July 1992 in Washington, D. C. The goal of this workshop was to bring photogrammetry and computer vision experts together in order to exchange ideas, concepts and approaches in camera calibration and orientation. These topics have been addressed in photogrammetry research for a long time, starting in the sec ond half of the 19th century. Over the years standard procedures have been developed and implemented, in particular for metric cameras, such that in the photogrammetric community such issues were considered as solved prob lems. With the increased use of non-metric cameras (in photogrammetry they are revealingly called "amateur" cameras), especially CCD cameras, and the exciting possibilities of acquiring long image sequences quite effortlessly and processing image data automatically, online and even in real-time, the need to take a new and fresh look at various calibration and orientation issues became obvious. Here most activities emerged through the computer vision commu nity, which was somewhat unaware as to what had already been achieved in photogrammetry. On the other hand, photogrammetrists seemed to ignore the new and interesting studies, in particular on the problems of orienta tion, that were being performed by computer vision experts.

Download or read book Time of Flight and Depth Imaging Sensors Algorithms and Applications written by Marcin Grzegorzek and published by Springer. This book was released on 2013-11-09 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cameras for 3D depth imaging, using either time-of-flight (ToF) or structured light sensors, have received a lot of attention recently and have been improved considerably over the last few years. The present techniques make full-range 3D data available at video frame rates, and thus pave the way for a much broader application of 3D vision systems. A series of workshops have closely followed the developments within ToF imaging over the years. Today, depth imaging workshops can be found at every major computer vision conference. The papers presented in this volume stem from a seminar on Time-of-Flight Imaging held at Schloss Dagstuhl in October 2012. They cover all aspects of ToF depth imaging, from sensors and basic foundations, to algorithms for low level processing, to important applications that exploit depth imaging. In addition, this book contains the proceedings of a workshop on Imaging New Modalities, which was held at the German Conference on Pattern Recognition in Saarbrücken, Germany, in September 2013. A state-of-the-art report on the Kinect sensor and its applications is followed by two reports on local and global ToF motion compensation and a novel depth capture system using a plenoptic multi-lens multi-focus camera sensor.
Download or read book Informed Data Selection for Dynamic Multi camera Clusters written by Arun Das and published by . This book was released on 2018 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional multi-camera systems require a fixed calibration between cameras to provide the solution at the correct scale, which places many limitations on its performance. This thesis investigates the calibration of dynamic camera clusters, or DCCs, where one or more of the cluster cameras is mounted to an actuated mechanism, such as a gimbal or robotic manipulator. Our novel calibration approach parameterizes the actuated mechanism using the Denavit-Hartenberg convention, then determines the calibration parameters which allow for the estimation of the time varying extrinsic transformations between the static and dynamic camera frames. A degeneracy analysis is also presented, which identifies redundant parameters of the DCC calibration system. In order to automate the calibration process, this thesis also presents two information theoretic methods which selects the optimal calibration viewpoints using a next-best-view strategy. The first strategy looks at minimizing the entropy of the calibration parameters, while the second method selects the viewpoints which maximize the mutual information between the joint angle input and calibration parameters. Finally, the effective selection of key-frames is also an essential aspect of robust visual navigation algorithms, as it ensures metrically consistent mapping solutions while reducing the computational complexity of the bundle adjustment process. To that end, we propose two entropy based methods which aim to insert key-frames that will directly improve the system's ability to localize. The first approach inserts key-frames based on the cumulative point entropy reduction in the existing map, while the second approach uses the predicted point flow discrepancy to select key-frames which best initialize new features for the camera to track against in the future. The DCC calibration methods are verified in both simulation and using physical hardware consisting of a 5-DOF Fanuc manipulator and a 3-DOF Aeryon Skyranger gimbal. We demonstrate that the proposed methods are able to achieve high quality calibrations using RMSE pixel error metrics, as well as through analysis of the estimator covariance matrix. The key-frame insertion methods are implemented within the Multi-Camera Parallel Mapping and Tracking (MCPTAM) framework, and we confirm the effectiveness of these approaches using high quality ground truth collected using an indoor positioning system.
