Paper Abstract

An effective multi-layer occlusion algorithm is put forward, which is composed of basic point to point occlusion detecting algorithm, status combining algorithm, effective feature point detecting algorithm and continuity optimizing algorithm. The status combining algorithm is designed to increase occlusion detecting algorithm's robustness according to the property that the display status of adjacent points is spatio-temporal piecewise-constant. By selecting virtual edge points with obvious feature on mesh contour to do status detecting and combining computation, higher occlusion detecting accuracy can be gained. By applying continuity optimizing algorithm on virtual points' display statuses, the rendering quality can be improved much. Experiment result proved that this algorithm can realize reliable multi-layer occlusion detection in augmented reality system.
