Abstract :
A method for segmenting three-dimensional overlapping surfaces is presented that is based on moving a light source in a horizontal plane relative to the surfaces to be segmented. Using a camera that is placed above the surfaces. The shadows cast by the surfaces at each light source angle are recorded and analyzed. The segmentation algorithm is simple and based on Boolean processing of the data. A set of experimental results demonstrates the robustness and usefulness of the method
