摘要

为提高中小企业钢珠直径检测效率、降低资本投入，提出一种基于机器视觉的钢珠直径测量方法。给出了系统的工作原理，对核心硬件进行了选型设计，搭建了实验平台。设计的系统用于测量直径为6mm和8mm的钢珠时，其标准差均小于等于0.007mm，重复性精度接近0.023mm；测量直径为6～8mm不同尺寸的钢珠时，系统的线性度理想。实验结果表明：该系统可以对钢珠精度等级在G100级及以下的钢珠进行高精度、非接触式检测。

Abstract:

In order to improve the efficiency of steel ball diameter detection in small and mediμm-sized enterprises and reduce the investment of capital, a method of steel ball diameter measurement based on machine vision was presented. First, the working principle of the system was given; secondly, the core hardware was designed and the hardware parameters were given; finally, the experimental platform was built. When the designed system was used to measure steel ball with diameter of 6mm and 8mm, the standard deviation is less than or equal to 0.007mm, and the repeatability precision approaches 0.023mm. The linearity of the system is ideal when measuring the diameter of steel ball from 6 to 8mm. The experimental results show that the system can be used for high-precision and non-contact detection of steel balls of grade G100 or below.

Key words: steel ball diameter machine vision measurement non-contact
