Key Issues in Modeling of Complex 3D Structures from Video Sequences

摘要

Construction of three-dimensional structures from video sequences has wide applications for intel-ligent video analysis. This paper summarizes the key issues of the theory and surveys the recent advances in the state of the art. Reconstruction of a scene object from video sequences often takes the basic principle of structure from motion with an uncalibrated camera. This paper lists the typical strategies and summarizes the typical solutions or algorithms for modeling of complex three-dimensional structures. Open difficult problems are also suggested for further study.
