Description:
Abstract Lens distortion is one of the highest elements affecting camera calibration. In this paper, a new improved algorithm for calculating the inverse of the best radial distortion model is presented. The presented method provides a model of reverse radial distortion. The method involves lens of focal length (190mm) with a Sony G camera, and calibrating them using Zhang method which entails a chessboard pattern to be detected from several positions, and an exact formula to calculate the inverse radial distortion. The results show that the highest order radial distortion is the better model to be reverse, it was shown that the 8th order radial distortion is the best model which contain a lowest value of distortion can be acquired after a number of iterations about 1.009842932 × 10-24, and this is the best value can be acquired without losing the accuracy, which produces low distortion performs as pincushion distortion. The new improved algorithm displays a good performance in obtaining least value for distortion coefficient.
