The instrument of the aircraft in the aviation industry shows the real-time navigation status of the aircraft, which is an important basis for judging the flight status. This paper uses the PnP algorithm to calculate the pose relationship between the camera and the target screen and solves the problem of the effect of the pose relationship between the camera and the target screen on image processing in visual inspection. And through the RAC model to improve the traditional DLT algorithm, which can quickly and accurately obtain the camera pose parameters. The algorithm uses radial constraints to add constraints to the DLT algorithm. While maintaining the low time consumption of the traditional DLT algorithm, it improves the accuracy of the DLT algorithm for camera pose estimation.
