| Abstract | In extracting the skeleton from the 3D complex model, the existing methods may produce errors that some branches are away from the center positions and some branches are redundant. As for this, a rectification method is proposed in this paper to correct these errors. After a coarse skeleton is extracted based on the distance field of the 3D model, the method investigates every joint to see whether it is away from its local center position, The investigation work by omitting radial rays evenly with the joint as the starting point to intersect the model's surfaces and studying the length distribution of the segments from the joint to the intersection points along the rays. For the joints away from the center positions, they are moved to the center and their related branches are also modified. Thus, the skeleton can be rectified automatically. Experimental results show the new method can efficiently rectify the skeleton and run fast, and generally the time for rectification takes up less than 2% of the time for extracting the skeleton. |
