【Objective】 This paper attempted to remove the difficulties in contours matching due to some complex contour pairs with nests,branches,and projective intersections in the process of the contour-based three dimensional(3D) surface model reconstruction.【Method】 On the basis of two defined contours distances,two criteria were proposed for contour matching to construct the simple contours pairs.A novel geometric amplification method was put forward to preprocess one-to-many contour pairs with projective interse...
