| 摘 要： | 提出了一种基于特征点的二维碎片轮廓匹配算法,有效地减少了匹配过程中的计算量。先对图像轮廓进行提取和去噪,计算轮廓曲线的曲率后选取特征点。接着计算特征片段的弧长与弦长比值,作为曲线特征进行匹配。实例表明,该方法提高计算的效率和匹配的成功率。

| Abstract: | For effectively reducing the amount of computation during the matching process, a method for two-dimensional fragments matching based on feature points is presented. The main idea of this method was effectively select the feature points by calculating the curvature after extract and de-noising the contour curve of the fragment. The ratio between arch length and chord length of the feature segment was used as a key to contour matching. Experimental result shows that this method improves computing efficiency and success rate of the matching. |
