视觉检测与激光精密测量在轴承加工检测中的应用

机器视觉测量技术是利用机器模拟人类视觉对待测工件的各种参数进行测量的一种新兴技术，测量速度快。利用面阵CCD传感器拍摄图像并结合相应的平面标定算法，即可测得工件的平面尺寸。此方法测量速度快，但精度相对较低。高精度激光位移传感器的测量精度较高，但测量速度相对较慢。结合以上两种视觉传感器的优点，提出一种同时具有高速、高精度特点的精密测量方法，并将其应用在精密轴承的制造、加工、检测中。

Application of Visual Detection and Precision Laser Measurement in Bearing Processing Detection

The machine vision is a new emerging technology that machine simulates human visual to measure various parameters of the measured workpiece, which has fast speed and simple structure. By capturing images using area array CCD sensor and combining with corresponding plane calibration algorithm, plane size of workpiece can be measured. This measuring method is fast, but the accuracy is relatively low. On the contrary, high precision laser sensor has high accuracy but low speed. By combining respective advantages of the two sensors, a measurement method was proposed which had characteristics of high speed and high precision. And it was used in manufacturing, processing, detection and measurement of precision bearing.
