The traditional method of radar shielding angle measurement is time-consuming and has low precision, which is difficult to meet the requirement of rapid and accurate radar shielding angle measurement. In this paper, the overall structure and application mode of radar shielding angle automatic measurement system are designed based on the angle measurement principle of computer vision. The implementation methods of key links such as camera distortion correction, installation error compensation and contour recognition and extraction are proposed, and compared with the traditional measurement methods. The test results show that the radar shielding angle measurement method based on computer vision can eatly improve the measurement efficiency and meet the application requirements.
