Paper Abstract

A method to determine positions and rotational angles of 3D objects in stereo images is proposed in this paper. First, range data of edge points of a left image are calculated by a stereo matching method. Next, a three dimensional model is rotated, translated and projected to a 2D plane, and the edges of the projected image are compared with those of the left image. The space transformation parameters which give the maximum matching ratio are searched by a Genetic Algorithm;GA. In the searching process of the proposed method, a set of space transformation parameters is regarded as chromosome of an individual, and a randomly generated population is evolved according to GA rules. Principle of the method and several experimental results are described.
