Research on the Dynamic Accuracy of Infrared Tracking and Measuring System by Offsetting Detection Method

利用动态精度靶标能够确定被检测光电经纬仪回转中心的空间位置。提出了动态精度偏置检测方法,实现对非中心红外跟踪系统动态角测量精度的检测,由于不需要在轴端镜头上加装分光镜组,不改变系统的转动惯量,提升了非中心系统的动态检测精度。对检测数据处理,验证了该方法的有效性,并在某型光电经纬仪检测中得到应用。

Taking advantage of dynamic precision targets can confirm the rotation center of the photo-electric theodolite. The dynamic accuracy by offsetting detection method was put forward, and the precision of dynamic angle measurement on non-center infrared tracking and measurement system were obtained. Because split lens is not needed to install at the end of the roller, and the rotational inertia is not changed, the dynamic detection accuracy of non-center system was improved. The data was processed to verify the effectiveness of the method, which has been applied to test a certain type of photo-electric theodolite system.
