计算机视觉在车灯面形检测中的应用

主要讨论了计算机视觉用于车灯面形误差检测中的一种应用方法。面形检测采用边缘定位的方法,并且结合了曲线拟合的方法求解一维位移场来计算误差。在实际生产中,不仅提高了检测精度,而同时也缩短了检测时间。更值得一提的是,若对检测模板稍加改动,该系统亦可用于其他型号的车灯或者其他零件。

This paper introduces an application method of computer vision in light surface shape measuring. It uses edge localization and curve fitting to solve one dimension displacement field and calculate the error. The method improves the measuring precision and cuts the measuring time and can be use for other unit after little change.
