基于光电伺服平台的动态角度测量方法研究

针对动态角度测量的成本高及精度低的问题，提出一种基于非合作目标视觉跟踪的光电测量方法。利用安装在被测对象上的光电伺服平台搭载相机和激光测距仪对非合作目标进行实时跟踪和距离测量，根据伺服平台输出的精密角度、非合作目标距离和被测角度之间的转化关系计算出被测动态角度值。研制了基于光电伺服平台的动态角度测量装置，并对其进行了精度标定和误差分析。利用高精度旋转台模拟被测动态角度进行实验，验证了测量方法的可行性。实验结果表明在测量空间11.082 m范围内，测角误差在±0.09°以内。

Research on dynamic angle measurement method based on electro-optical servo platform

Aiming at the measurement problem of high cost and low precision in dynamic angle, an electro-optical measurement method based on non-cooperative target vision tracking is presented. By using electro-optical servo platform mounted on the measured object to carry the camera and the laser rangefinder for the real time tracking and distance measurement of the non-cooperative target, the dynamic angle value is calculated according to the conversion relationship between the high precision angle of measurement of the servo system and the distance of the non-cooperative target. A dynamic angle measuring device is developed, and its precision calibration and error analysis are carried out. Using the high precision manual displacement table to simulate the measured dynamic angle to experiment, the feasibility of the measuring method is verified. The experimental results show that the measured angle error is 0.09° within the range of 11.082 m.
