Camera sensor installation state calibration method

The invention discloses a camera sensor installation state calibration method, and relates to the technical field of camera calibration, and the method comprises the steps: employing a standard camera to shoot an initial image of a to-be-calibrated camera disposed on a test tool from the front side; processing the initial image into a to-be-calibrated image of an area where the front section of the to-be-calibrated camera is located, which is shot by vertically facing the front section of the to-be-calibrated camera, by using a scale target on the test tool and a reflective cursor on the front section of the to-be-calibrated camera; compared with a conventional calibration method, the method has the advantages that the method is simpler, and after the method is converted into state measurement, the method is more intuitive and has better repeatability. The application of the test tool improves the repeatability of the measurement and calibration work, and the method can reduce the unfixation of the relative p
