可编程动态旋转靶标标定方法

Calibration of programmable dynamic target

动态旋转靶标可以给出检测光电测量设备跟踪精度和测量精度的空间角度真值,针对动态靶标的空间角度标定问题提出了基于线阵CCD标定和视频判读标定的方法。他们是建立在对动态靶标空间位置重复性进行统计的基础上,利用Excel等软件完成脱靶量数据处理。实验结果表明,所提出的方法能够消除由于曝光、扫描和转移等时间不同步问题引起的单点电视脱靶量误差,能够实现对动态靶标的标定。

Some methods based on statistics for dimensional position and data processing by such software as Excel are suggested for the calibration of the dimensional angle shown by a dynamic target using linear matrix CCD and video interpretation. Experimental results show that these methods can be effectively used to reduce the TV undershoot errors resulting from asynchronous exposal, scan and transfer, and consequently achieve the calibration of dynamic target.
