Reconstruction of Time-Dependent Three-Dimensional Scenes Based on Analysis of Sequences of Stereo Images

摘要

The purpose of this work is. foremost, to provide a framework for expressing the ideas behind the analysis time-dependent three-dimensional scenes. Secondly, to integrate the various results that have appeared on the analysis of sequences of stereo images. The technique based on analysis of the structure of the 3D scene is used to detect dynamic components in the synchronous stereogram sequences. The recursive estimation of geometrical and brightness transformations of image fragments is used to identify corresponding points in sequences of images. The results of processing the simulated sequences of synchronous stereograms are presented. In this work we also propose and examine the method of the estimation of three-dimensional coordinates and speeds of a spatial object structure from the sequence of images obtained from a moving, partially calibrated, camera. Experimental results of processing of model and real sequences are presented.
