Description

We present a novel approach for 3D reconstruction based on a set of images taken from a static scene. Our solution is inspired by spatio temporal analysis of video sequences. The method is based on a best fitting scheme for spatio temporal curves, that allows us to compute 3D world coordinates of points within the scene. As opposed to a large number of current methods, our technique deals with random camera movements in a transparent way, and even performs better in these cases than with restrained motion such as pure translation. Robustness against occlusion and aliasing is inherent to the method as well.
