摘　　要：提出了一种基于图像处理的透镜包边方法,根据待包边透镜的特点确定了光路中各参数,由面阵CMOS器件接收透镜反射的十字叉丝像,并通过图像处理的方法计算透镜的中心偏,以此为依据调整透镜位置,达到误差允许范围,然后加工金属外圆,完成包边。对测量系统、电机控制和软件实现作了详细说明,给出了实验结果。实验结果表明,该方法操作简单、测量精度高,可有效减小透镜中心偏。A method of lens jacket based on image processing is presented, which can reduce the eccentricity of lens effectively. Based on the features of the lens to be jacketed, the parameters of the optical path are calculated. An area array CMOS device is used to get the reflected cross image from the lens. By using image processing methods to get the eccentricity value, the position of the lens is adjusted to reach the tolerance and the jacket is machined. The testing setup, the motor control system and the software are described. The experiment result shows the method is effective in reducing eccentric error.
