Abstract

In this paper, a non-contact method for measuring scanning speed of photoelectric radar scanning mirror is proposed, which collects scanning video of photoelectric radar scanning mirror by high-speed camera, and detects the motion track of scanning mirror by image tracing in image processing, then corrects the distortion of scanning track by using the method of projection transformation of space coordinate system, and in the end, the scanning speed is obtained by differentiating the time. This method is suitable for all line photoelectric radar products, and it is simple, fast and easy to operate.
