动态调节圆半径曲面重建算法的改进

为实现对散乱数据点划分三角形网格的曲面重建,克服实体表面存在阶跃边缘而难以确定圆半径的问题,改进用动态调节圆半径产生三角形网格并实现曲面重建的算法,将散乱数据点转化为二维图像数据,并进行三角形网格划分.实验结果表明,虽然改进算法效率有所下降,但对表面存在阶跃边缘的实体有较好的重建效果.

Improved surface reconstruction algorithm using dynamic regulation of circle radius

To achieve the surface reconstruction for the triangle mesh of scattered data points, and overcome the shortcoming that the circle radius is difficult to identify for the existence of step edge on solid surface, the algorithm of generating triangular mesh by dynamic regulation of circle radius and implementing surface reconstruction is improved. The scattered data points are transformed into 2D image data and the image is meshed by triangle element. The experimental results show that the improved algorithm has a better reconstruction effect for solid surface with step edge although the efficiency decreases.
