Abstract: To realize the non-closed surface reconstruction accurately, a threshold segmentation algorithm based on triangle perimeter which could be used to remove the enclosed spurious surface was proposed. The sampling points were selected from triangle perimeter, and the threshold was calculated automatically by comparing the Enclidean distance between sample points and input points. Thus the non-closed surface was obtained by threshold segmentation from enclosed surface. The experiments results showed that the proposed method had low complexity, high efficiency, and strong robustness. Moreover, it could remove the spurious surface but not affect the precision of original surface.
