摘要
目前使用的孔洞修补方法对于包含多种曲面的孔洞是无效的或者修补效果不理想。针对这个问题该文使用了一种定宽的切片方法来修补这类孔洞。通过密度法确定切片宽度后,对切片进行投影并进行拟合,通常可以使用多项式拟合的方法进行拟合。通过实验分析,可以得知切片方法的修补效果良好,对比不同的拟合方法得到最优拟合方法。
At present,the hole reparing method is useless or unsatisfactory to the hole with many curved surface. Aimed at this problem, this paper uses a fixed-width slicing method to repair this kind hole. Through the density method, the slicing width is determined, the slicing width is shadowed and fitted. The polynomial fitting method is usually used to fitting. Through experiment analysis, the results show the repairing effect of slicing method is good. Compared with different fitting method, the best fitting method is obtained.
