An Approximating Algorithm Research on Reconstruction of Complicated Curved Surface
For reconstruction of complicated curved surface, an approximating algorithm on handling 3D points cloud data is proposed. In this algorithm, the coordinate information of nodes both in internal and external regions of partition interpolation is used to realize minimized least squares approximation error of surface fitting. The changes between internal and external interpolation regions are continuous and smooth. Meanwhile, surface shape has properties of local controllability, variation reduction, and convex hull thanks to this algorithm. The practical example proves that this algorithm possesses a higher accuracy of curved surface reconstruction and also improves the distortion of curved surface reconstruction while typical approximating algorithms and unstable operation are used.
