Description: 针对现有的PCB（Printed Circuit Board）缺陷视觉检测系统实时性较差，难以检测线宽过窄等问题，首先对 PCB 缺陷图像进行小波变换压缩，提高了系统实时性；然后应用小波边缘检测算法对缺陷图像边缘精确定位，在图像小波变换局部模极大值对应的梯度方向上计算边缘点距离，根据特定规则提取、识别并定位特定缺陷，实验结果表明上述方法简单有效。-For the existing PCB (Printed Circuit Board) real-time visual inspection system for defects is poor, difficult to detect a narrow line width and other issues, first of all defects on the PCB image compression using wavelet transform and improve the system real time and then apply the wavelet edge detection algorithm precise location of the defect edge in the wavelet transform and local maxima correspond to the gradient direction of edge points to calculate the distance, according to a specific rule extraction, to identify and target specific defects, experimental results show that the method is simple and effective.

Description: 待检测pcb板和标准pcb对比，然后对待测pcb腐蚀及膨胀处理，进行缺陷标注显示图像并输出焊盘缺失数，导线缺失数，短路数等。所以源图像均有，并再次测试无误，可以直接运行。-To be detected and the standard pcb board pcb contrast, then treat corrosion test pcb and the expansion process, defect labeling displays images and outputs missing number pad, missing a few wires, short circuit and number. So were the source image, and test again correctly, you can run directly.
