Embodiment
[0038] A method for measuring the inclination angle of the horizontal plane of a camera, comprising the following steps:
[0039] Step 1. Place the calibration board on the calibration board loading platform 5, set a part of the calibration board as a public area, control the movement of the working platform 1 by moving the motor, the calibration board enters the camera field of view, and take an image of the calibration board. This image includes the public domain of Baoding Edition;
[0040] Step 2. Keep the Y-axis 2 of the motor still, move the working platform 1 along the X-axis 4 of the motor by a step length Δd, and take another image of the calibration board, which includes the common area of the calibration board; among them, the images of the two calibration boards the images exist in the same common area;
[0041] Step 3. Process the two images of the calibration board, and the inclination angle of the camera horizontal plane is based on Calculated, where ΔV is ...
