Abstract:This paper proposes a multi-layer surface reconstruction method based on a special oriented status octree. The method is designed to handle point sets with missing normal information and with holes. First, the octree cells distributed on holes are detected by active contours. By using hidden point removal (HPR) operator, the inside or outside status of each corner of octree cells are calculated, and the mono-oriented status octree is constructed. Then the normal direction of the initial points set inside the status octree is determined by in-cell normal detection method, and the parallel multi-layer surface reconstruction from k-nearest neighbors is carried out by using the status octree. The proposed method improves the construction efficiency while guaranteeing the construction quality.
