【摘要】 不规则碎片的拼接,按照碎片特征,可分为基于内容的拼接和基于轮廓的拼接。我们提出一种基于轮廓,利用待拼接边缘的边长和灰度互相关的新方法来寻找局部匹配中的真实匹配。首先提取碎片轮廓并进行角点检测,计算边缘边长,然后对等边长的两碎片进行灰度互相关计算,通过比较确定真实匹配。仿真实验表明该方法简单有效。更多还原

【Abstract】 The reassembly of irregular fragments can be divided into content-based reassembly and contour-based reassembly according to the characteristics of fragments. A new method based on contour is proposed to find the real local matching, using the length of edge to be spliced and intensity cross-correlation. Firstly, the contours of the fragments are extracted and the corner points are detected. By calculating the edge length of fragments, the intensity cross-correlations of two fragments with equal edge length are calculated. The real matching is determined by comparison. Simulation results show that the new method is simple and effective.更多还原
