资料介绍

针对印刷过程中印刷电路很容易产生短路、断路、毛刺等缺陷问题,提出一种基于 ORB ( oriented FAST and rotated Brief)算法的印刷电路检测方法。首先,针对原始ORB特征匹配算法出现大量误匹配的问题,提出了一种基于空间距离的提纯法对匹配对进行提纯;其次,利用提纯后的匹配点计算待测图像和模板图像的仿射变换矩阵;再次,利用图像差分检测法对印刷电子屏印刷电路检测。结果表明:该算法在速度与精度方面均有提高。

In the printing process printed circuit is easy to produce defects in short circuit,open circuit,burrs and so on, this paper presents a robust, fast and precise based on ORB ( oriented FAST and rotated Brief ) printed circuit detection. First of all, according to the original ORB feature matching algorithm which is the emergence of a large number of false matching problem,this paper puts forward a method based on spatial distance method for the purification of the matching pairs are purified, then calculates the image to be measured using the matching point purified and the affine transformation matrix template image, finally, it detects the electronic screen printed circuit by using the image difference. The results show th...
