摘　　要：提出了一种利用CCD器件检测激光测距机光轴平行性的方法,利用CCD和图像采集卡组成的图像采集系统对激光测距机瞄准系统十字分划像和发射的激光光斑进行采集,通过图像处理技术对采集到的图像进行处理,并确定激光光斑中心和十字分划中心坐标,即可获得激光测距机的光轴平行性误差。该方法能够实时、定量地检测光轴偏差,检测精度高,操作简单,有效地解决了传统方法只能定性地估算误差,人眼主观判断误差较大等问题。Presented is a method based on CCD for detecting the optic-axes parallelism of laser-range-finder is presented. The images collecting system, made up of CCD and image board, collects laser spot image and the cross division line image of the aiming system in the laser-range- finder. The computer can dispose these images, then obtain the centre coordinates and detect the optic-axes parallelism of the laser range finder. This method can detect the parallelism in real time with a high precision and simple operation. This method solves such problems existing in traditonal systems as only realization of qualitative error analysis.
