一种高效的三维轮廓曲线匹配算法
Efficient Matching Algorithm for 3D Contour Curve
摘要
Abstract
Aiming at the problem of fragment matching in 3D fragment reassembly, this paper proposes a rapid contour curve matching algorithm.In the algorithm, the curve is expressed by B-spline curve, and curvature, torsion and normal vector are calculated.In the matching process, the type of feature point is classified according to its neighbor surface, and the similarity of the two feature section is measured according to the Euclidean distance of the feature points.The normal vector is used to verify the matching probability of similar space curves.Experimental results show that the algorithm is stable and efficient.关键词
