A Hierarchical Determination of Optimal Camera and Light-Source Positions for Model-Based Recognition

component of the reflection has been considered (2, This paper propose a hierarchical design method of camera and light-source positioning for model based vision. In this method, first, the geodesic dome is constructed for given objects t o place their initial candidate positions of camera and light-source. Then, they are selected out step by step using criterions of viewing angle, specular reflection, and edge contrast, and the final optimal positioning is obtained. We show that our hierarchical and step by step strategy achieves great reduction of computational time over the conventional direct configuration method to obtain good contrasts of object edges.
