Multi-scale structure from multi-views by Δ/sup 2/G filtered 3D voting

Abstract

into voxels. The values of all voxels are set to aero. This paper proposes a multi-scale 9D structure recovery method which divides the scene space into vozels and votes for them using the sight lines of the camem from coarse to fine. This paper also analyzes the mechanism behind the infEuence of the image quantization error and the position error of the camera's optical center. Both errors can be diminished by v'G filtering the voted wozel space. A multi-scale 3D structure of objects is successfully generated from a real amage sequence of 6 frames using this method.
