| 摘 要： | 针对目前VCM磁钢片轮廓尺寸的检测方法存在检测速度慢、精度低等问题，设计了基于机器视觉的VCM磁钢检测系统的总体结构。视觉检测系统采用了中值滤波滤除噪音，利用Canny算子定位边缘轮廓和8-连通法提取图像边缘信息，采用基于链码的实时拐角检测算法求拐点，对轮廓线进行分段识别和重构，并用最小二乘法拟合轮廓，实现尺寸检测。用该系统对VCM磁钢片样品进行实验及数据分析，并与传统的三坐标测量仪的检测结果进行对比实验。实验结果证明了该系统能满足VCM磁钢片的实际工业在线检测需求。

| Abstract: | The structure of inspection system on VCM based on machine vision is designed to meet the problems of dimensional inspection methods on VCM at present such as low speed, low grade precision and so on. Visual inspection system uses median filter to filter out noise,and Canny operator to position edges and 8-connectivity method to exact image edge information, and the real-time corner detection algorithm based on the chain code for inflection point, and sub-recognition and reconstruction of contour lines, and... |
