Abstract
This paper proposes a hierarchical design method of camera and light-source positioning for model based vision systems. In this method, first, the geodesic dome is constructed for given objects to place initial candidate positions of camera and light-source. Then, the candidate positions are selected out step by step using criterions of viewing angle, occlusion by other objects, specular reflection, and edge contrast. Then the final optimal positionings are obtained. We show that our hierarchical and step by step strategy achieves great reduction of computational time over the conventional direct configuration methods to obtain good quality of images with high contrasts of object edges.
