Research of Eliminating Occlusion in Visual Construction of ThreeDimensional Objects
How to solve the occlusion problem effectively is a difficult subject during the progress of acquiring unknown object’s threedimensional (3D) digital model. So a new view planning which can cope with occlusion correctly is proposed. The reconstruction progress is divided into two steps: 360°side surface reconstruction and upper surface reconstruction. Firstly, the contour predictable model of the occlusion is acquired and the position coping with the occlusion information is obtained with the visible region. Secondly, after the completion of side surface reconstruction, the visible criterion of the boundaries of the upper surface of the object is predicted and the best turnover angle of the vision system is defined where the vision system can acquire the maximal information of the upper surface. And then, the normal vector of the line connecting the occlusion boundary points is calculated, based on which a planning scheme to solve the occlusion is proposed. Finally, the experimental result of reconstructing the 3D real model shows that the method is feasible in practical implementation.
