Abstract: 3D reconstruction can be understood as the fitting of curves and surfaces,and the complex surfaces characteri-zed by triangulation is widely applied.This paper proposed a detail triangulation method based on depth feature of point cloud.The reconstruction method of foot point cloud data based on line laser scanning was introduced in detail.First,the strip data points are segmented by piecewise processing,the threshold is setted to supplement the leakage points and delet the useless segments.Then,the 8-adjacency domain method is used to find the boundary points and to sort the closed curves,and the band data points are filtered by Savitzky-golay.Finally,the basis is based on the method of filtering the banded data points.The topological relationship of two-dimensional mesh forms a quadrilateral network,and the detail triangulation method is used to segment the faces.Experiments show that the method of surface reconstruction is fast,and the boundary and internal details are obvious.

Key words: 3D reconstruction, Concavo convex point, Curvature feature, Depth image, Triangulation
