Embodiment
[0053] The invention proposes a method for determining internal parameters of a parabolic catadioptric camera by using Veronese mapping and a checkerboard target. The embodiment of the present invention is described in more detail below with an example, and the method in the present invention is used to calibrate the parabolic catadioptric camera in the experiment. The specific steps are as follows:
[0054] 1. Solve the extended homography matrix of the catadioptric system
[0055] The resolution of the captured image of the parabolic catadioptric camera is , shoot the checkerboard template at different positions, and take 3 images. Read in the image, use the Edge function in the Matlab software to extract the corner coordinates of the checkerboard, respectively take the 12 corner coordinates of the checkerboard on each image, and the homogeneous coordinates of the three images are respectively:
[0056] The 12 corner coordinates of the first image, each column is a corner...
