摘　　要：以机器视觉系统为基础,利用计算机图像处理技术,对预处理后的边缘图像,采用基于点Hough变换的圆形图像亚像素检测算法,实现了轴承内径的亚像素在线检测。试验证明,该检测系统具有非接触、无损伤、高速度、低成本的优点,并且具有很好的通用性,可广泛应用于其他行业产品的在线检测。Based on machine vision system, an algorithm for circle subpixel edge detecting based on point Hough transform is adopted for the pre - processed edge image, by virtue of computer image processing technology. And a subpixel detection technology for the bore diameter of bearings is realized successfully on - line. The experiments demonstrate that the system has many advantages such as non - touching, high speed, low cost, and so on, and the method is universal so that can be applied widely to on - line inspection of other products.
