| Abstract: | Reasonable radius compensation can improve the precision of reverse engineering greatly. Based on the analysis of existing radius compensation algorithms and corresponding advantages and disadvantages,a new algorithm of triangle grid radius compensation was proposed by introducing the idea of Delaunay triangulation. At the same time,some key techniques such as criteria for triangulation optimization and treatment of boundary points were expounded in detail. At last,radius compensation of data points on blad... |
