平面碎片匹配算法的研究

摘要

On the base of analyzing geometrical character of planar curve,an algorithm based on curvature etc. invariant is presented which is about planar irregular curve raatching.In this method,look for beginning matching points by extracting corner points of planar irregular curve and matching corner points,at the same time make use of geometrical character that corresponding points have the same curvatures or equivalent geometrical character to perform irregular curves matching.And theory and experiment prove that this algorithm is feasible.%在分析平面曲线的几何特性的基础上,提出了一种基于曲率等不变量的平面非规则边界曲线匹配的算法,该方法通过提取平面非规则曲线的角点和匹配角点来寻找初始匹配点.同时利用对应点的曲率相等或者等价的几何特性来匹配平面非规则曲线.并且在理论和实验上对方法的可行性进行了证明.
