Abstract
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.
