| 摘 要： | 序贯相似性检测算法（sSDA）是针对传统的模板匹配算法提出的一种高效的图像匹配算法，但是SSDA算法难以满足螺纹检测的实时性。针对传统SSDA算法的不足，提出了一种基于螺纹边缘图像的快速SSDA算法。该方法用形态学对螺纹图像进行了边缘提取，然后只在边缘处进行匹配，从而大大减少了匹配的次数，同时提出了减小匹配运算量的方法。

| Abstract: | The sequential similarity detection algorithm(SSDA) is proposed to improve the conventional image matching,which is an efficient image matching algorithm.But the SSDA algorithm can not meet the real-time of thread detection.For the lack of traditional SSDA algorithm,a fast SSDA algorithm based on the edge image of thread is proposed.This method extracts edge points of thread based on morphology,then match on the edge points.This can reduce the number of the match greatly.At the same time,a method is propose... |
