Embodiment Construction
[0024] In one embodiment, a method for acquiring a camera monitoring area of a vehicle, the vehicle may be an unmanned vehicle or a manned vehicle. like figure 1 As shown, the method includes the following steps:
[0025] Step S110: Obtain the internal parameter matrix of the camera installed on the vehicle, as well as the transformation matrix and translation matrix from the vehicle's ground projected coordinate system to the image coordinate system.
[0026] Calibrate the camera installed on the vehicle to obtain the internal parameter matrix A of the camera and the projected coordinate system O of the vehicle ground c x c Y c to the image coordinate system O p x p Y p The transformation matrix R cp and translation matrix t cp , used for subsequent coordinate transformation. The internal parameter matrix is the characteristic parameter of the camera, which represents the proportional relationship between the actual size of the object and the size in the picture....
