A Genetic Algorithm for 3D Shape Recovery
物体三维形状恢复的遗传算法方法

In this paper, we propose a novel method to recover the 3D shape of objects from two image sequences. At first, for eliminating the limitations of the conventional shape from shading methods, we develop a spherical light source model. Based on this model, a fast genetic algorithm is then used for the shape and reflectance recovery from the diffuse reflection component extracted from a pair of image sequences. An image sequence is acquired with each image taken at a different light position. As a result, the normal of a surface patch which is not in the light source moving plane can also be estimated robustly. Our method is verified by both real and simulated experiments.
