| 摘 要： | 本文依据Shepard基本原理,提出了一种新的自适应曲面重建算法。该算法首先利用LMS方法优化改进型Shepard算法,求出由粗糙到细致的控制网格。再利用双线性插值方法进行曲面重建,同时保证曲面的平滑性。实验结果表明本文提出的算法能够有效地重建较高精度的曲面。

| Abstract: | This paper proposed a new adaptive algorithm for surface reconstruction,according to the basic principles of Shepard. This algorithm first generates control grids from rough to finely,using the modified Shepard algorithm optimized by the LMS method. The surface is reconstructed by bilinear interpolation,while keeping the smoothness. The result shows that this algorithm is effective on more accurate surface reconstruction. |
