Abstract :
Distortion is the main problem of CCD camera in image processing. In this paper, two self-tuning calibration methods of camera lens distortion are presented. Both the methods improve the calibration of camera when solving the problems of radial distortion, decentering distortion and prism distortion. In addition, the proposed methods do not need complex mathematical equation to calibrate the camera. This helps to calibrate the camera on line. Simulation and experimental results with the conventional method verify the good performance of the proposed methods.
