Book Synopsis Articulated Object Reconstruction from Interaction Videos by : Xiang Xu
Download or read book Articulated Object Reconstruction from Interaction Videos written by Xiang Xu and published by . This book was released on 2021 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis studies the problem of articulated object reconstruction from an input video. Our focus is on estimating the shape, pose, and part motion of an articulated object during human-object manipulation. The task is challenging as the object is dynamically changing and 3D reconstruction from 2D is inherently ambiguous. To enable research in this direction, we first create D3D-HOI: a dataset of monocular videos with ground truth annotations of 3D object shape, pose and part motion from human-object interaction videos. Our dataset consists of several common categories of articulated objects in diverse real-world scenes, observed from a variety of fixed camera view points. Each manipulated object (e.g., microwave) is represented using a 3D parametric model that best fits the captured data. We then annotate the size, pose, and part articulation values at every frame. A novel optimization-based method is proposed based on differentiable renderer and human-object interaction terms, which leverage the human pose for better inferring of the object spatial layout and dynamics. We evaluate this new approach on our dataset, demonstrating that human-object relations can significantly reduce the pose and motion errors on real-world articulated objects. Code and dataset are available at the following link (https://github.com/facebookresearch/d3d-hoi).

Book Synopsis Leveraging Proposals and Shape Reconstruction for Monocular 3D Object Detection and Object-centric Stereo Matching for 3D Object Detection by : Alexander Pon
Download or read book Leveraging Proposals and Shape Reconstruction for Monocular 3D Object Detection and Object-centric Stereo Matching for 3D Object Detection written by Alexander Pon and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safe autonomous driving requires reliable 3D object detection-the task of estimating 3D bounding boxes for objects of interest in the scene. This thesis introduces a monocular 3D object detector that accurately estimates the 3D position of objects by first generating 3D proposals, using a novel 2D bounding box prior, then refining them in a second stage. Depth information is further learned by jointly optimizing these predicted object positions and the task of point cloud reconstruction. A stereo 3D object detector is also introduced. Compared to previous methods, it only estimates disparities for pixels belonging to objects of interest, which mitigates point cloud artifacts seen in full scene depth maps and improves runtime speed. Moreover, a novel point cloud loss is presented to combat the issue that typical disparity loss functions insufficiently penalize far depths. Both detectors achieve state-of-the-art results on the KITTI dataset when compared to other camera-based methods.

Book Synopsis Multiple View Geometry in Computer Vision by : Richard Hartley
Download or read book Multiple View Geometry in Computer Vision written by Richard Hartley and published by Cambridge University Press. This book was released on 2004-03-25 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: A basic problem in computer vision is to understand the structure of a real world scene given several images of it. Techniques for solving this problem are taken from projective geometry and photogrammetry. Here, the authors cover the geometric principles and their algebraic representation in terms of camera projection matrices, the fundamental matrix and the trifocal tensor. The theory and methods of computation of these entities are discussed with real examples, as is their use in the reconstruction of scenes from multiple images. The new edition features an extended introduction covering the key ideas in the book (which itself has been updated with additional examples and appendices) and significant new results which have appeared since the first edition. Comprehensive background material is provided, so readers familiar with linear algebra and basic numerical methods can understand the projective geometry and estimation algorithms presented, and implement the algorithms directly from the book.

Over the last few years tremendous progress has been made in this area. On the one hand important new insightshavebeenobtainedresultinginmore exibilityandnewrepresentations.Onthe other hand a number of techniques have come to maturity, yielding robust algorithms delivering good results on real image data. Moreover supporting technologies – such as digital cameras, computers, disk storage, and visualization devices – have made things possible that were infeasible just a few years ago.

Book Synopsis Control Problems in Robotics by : Antonio Bicchi
Download or read book Control Problems in Robotics written by Antonio Bicchi and published by Springer Science & Business Media. This book was released on 2007-07-12 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ?eld of robotics continues to ?ourish and develop. In common with general scienti?c investigation, new ideas and implementations emerge quite spontaneously and these are discussed, used, discarded or subsumed at c- ferences, in the reference journals, as well as through the Internet. After a little more maturity has been acquired by the new concepts, then archival publication as a scienti?c or engineering monograph may occur. The goal of the Springer Tracts in Advanced Robotics is to publish new developments and advances in the ?elds of robotics research – rapidly and informally but with a high quality. It is hoped that prospective authors will welcome the opportunity to publish a structured presentation of some of the emerging robotics methodologies and technologies. The edited volume by Antonio Bicchi, Henrik Christensen and Domenico Prattichizzo is the outcome of the second edition of a workshop jointly sponsored by the IEEE Control Systems Society and the IEEE Robotics and Automation Society. Noticeably, the previous volume was published in the Springer Lecture Notes on Control and Information Sciences. The authors are recognised as leading scholars internationally. A n- ber of challenging control problems on the forefront of today’s research in robotics and automation are covered, with special emphasis on vision, sensory-feedback control, human-centered robotics, manipulation, planning, ?exible and cooperative robots, assembly systems.

This second edition has been revised and updated throughout, with 130 pages of new material on such topics as locomotion, perception, localization, and planning and navigation. Problem sets have been added at the end of each chapter. Bringing together all aspects of mobile robotics into one volume, Introduction to Autonomous Mobile Robots can serve as a textbook or a working tool for beginning practitioners. Curriculum developed by Dr. Robert King, Colorado School of Mines, and Dr. James Conrad, University of North Carolina-Charlotte, to accompany the National Instruments LabVIEW Robotics Starter Kit, are available. Included are 13 (6 by Dr. King and 7 by Dr. Conrad) laboratory exercises for using the LabVIEW Robotics Starter Kit to teach mobile robotics concepts.
