Abstract: Abstract of thesis entitled 3D Metric Reconstruction from Uncalibrated Circular Motion Image Sequences submitted by Zhong Huang for the degree of Doctor of Philosophy at The University of Hong Kong May 2006 Circular motion is a practical motion for model acquisition. This thesis addresses the problem of metric reconstruction from uncalibrated circular motion image sequences from both the theoretical and practical viewpoints. The cameras are assumed to have constant intrinsic parameters, but the actual camera motion need not be known. A stratified geometric approach is taken to devise solutions. Algorithms for motion estimation, metric reconstruction and surface extraction are developed, by which an object model can be reconstructed systematically. First, a reconstruction method for circular motion is developed with the aim of estimating the unknown rotation angles of the camera robustly. This is achieved by enforcing the knowledge of the type of motion (i.e. the rotational motion constraint) in a factorization-based projective reconstruction, yielding what is called a circular projective reconstruction. Furthermore, a three-stage reconstruction approach with image points incrementally added in different stages of reconstructions is presented for computing a circular projective reconstruction from a long circular motion image sequence. This approach can cope with the missing data problem which inherently exists in a long image sequence. Second, the problem of computing a metric reconstruction from a circular projective reconstruction is considered. Two camera calibration methods are II proposed for resolving the metric reconstruction ambiguity in a circular projective reconstruction by exploring available calibration constraints. The methods are based on a new decomposition of a rectifying homography and developed for the cases involving one circular motion image sequence or one circular motion image sequence with one additional image. Finally, a fast model reconstruction method is proposed to extract the surface of an object from a calibrated circular motion image sequence. It is shown that 3D rim curves with known order enclosing the object can be reconstructed by means of the object silhouettes and feature points. These ordered rim curves allow a triangulated surface mesh of the object model to be constructed efficiently. Throughout the thesis, experimental results are given to demonstrate the performance of the proposed algorithms, and these results are shown to be both accurate and stable.

The fully automated estimation of the 6 degrees of freedom camera motion and the imaged 3D scenario using as the only input the pictures taken by the camera has been a long term aim in the computer vision community. The associated line of research has been known as Structure from Motion (SfM). An intense research effort during the latest decades has produced spectacular advances; the topic has reached a consistent state of maturity and most of its aspects are well known nowadays. 3D vision has immediate applications in many and diverse fields like robotics, videogames and augmented reality; and technological transfer is starting to be a reality. This book describes one of the first systems for sparse point-based 3D reconstruction and egomotion estimation from an image sequence; able to run in real-time at video frame rate and assuming quite weak prior knowledge about camera calibration, motion or scene. Its chapters unify the current perspectives of the robotics and computer vision communities on the 3D vision topic: As usual in robotics sensing, the explicit estimation and propagation of the uncertainty hold a central role in the sequential video processing and is shown to boost the efficiency and performance of the 3D estimation. On the other hand, some of the most relevant topics discussed in SfM by the computer vision scientists are addressed under this probabilistic filtering scheme; namely projective models, spurious rejection, model selection and self-calibration.

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.

In this book, the design of two new planar patterns for camera calibration of intrinsic parameters is addressed and a line-based method for distortion correction is suggested. The dynamic calibration of structured light systems, which consist of a camera and a projector is also treated. Also, the 3D Euclidean reconstruction by using the image-to-world transformation is investigated. Lastly, linear calibration algorithms for the catadioptric camera are considered, and the homographic matrix and fundamental matrix are extensively studied. In these methods, analytic solutions are provided for the computational efficiency and redundancy in the data can be easily incorporated to improve reliability of the estimations. This volume will therefore prove valuable and practical tool for researchers and practioners working in image processing and computer vision and related subjects.
