Abstract :
A multiscale 3-D structure recovery method is proposed. It divides the scene space into voxels and votes for them using the sight lines of the camera from coarse to fine. The mechanism behind the influence of the image quantization error and the position error of the camera´s optical center is analyzed. Both errors can be diminished by Δ2G filtering the voted voxel space. A multiscale 3-D structure of objects is successfully generated from a real image sequence of six frames using this method
