摘要
介绍了一种高精度双轴自准直仪,它采用面阵CCD器件作为光电传感器,利用自准直原理实现二维角度的测量。对图像处理系统进行了重点阐述,采用直线拟合求十字线交点的方法保证了测量精度。
A high accuracy two_axis autocollimator is introduced in this paper, which uses the surface array CCD components as photoelectricy sensor, and two-axis angle by the theory of autocollimate are measured. In this paper, the system of image processing is explained in detail, and the method of matching straight line to get the point of cross line promise measure accuracy.
