摘　　要：针对高曲率零件表面缺陷检测及外形尺寸测量的问题,设计实现了基于机器视觉的兼顾缺陷检测及外形尺寸测量两种功能的测量系统。在同一系统中,固定的光学系统放大倍数能满足检测表面微米级大小缺陷的要求,对外形尺寸测量要移动零件,拍摄多幅边缘图像,记录移动距离并计算零件两侧边缘在图像中的距离,得到最终的外形尺寸。解决了表面缺陷高精度检测和外形尺寸大范围测量的矛盾。实验证明:系统具有可靠、高效的特点。Aimed at the problem of high curvature bitty part surface flaw and boxed dimension, a whole based on machine vision program which balances between the flaw detection and dimension measurement is designed, the requirement of micron flaw in surface detection is satisfied, the boxed dimension measurement is accomplished by moving the part and taking several edge images, recording the moving distance and counting the distance of edges in image, combining the two distances then getting the boxed dimension.
