[0033] The invention proposes to use three non-parallel straight lines in space as targets to linearly determine the internal parameters of the parabolic catadioptric camera. The experimental module structure diagram that the present invention adopts is as figure 1 shown. The implementation of the present invention will be described in more detail with an example below.
[0034] The experimental template used by the parabolic catadioptric camera calibration method based on three non-parallel straight lines in space is three non-parallel straight lines in space, such as figure 1 shown. The three straight lines are , , , using the method in the present invention to calibrate the parabolic catadioptric camera used in the experiment, the specific steps are as follows:
[0035] 1. Fit the curve equation of the straight line projection in the image
[0036] The image resolution that the present invention adopts is 640 * 480 pixels, takes 1 experimental picture with the par...
