Abstract

Most of cameras follow pinhole camera model. However, result of this model makes some undesirable effects in wide angle lens. The most serious problem among these effects is radial distortion which appears heavily in fish-eye images. Several geometric models for correcting radial distortion of fish-eye lens are developed. Most of these models require only one parameter. However, correcting with one parameter is limited to correct both central and outer part simultaneously. Aim of this paper is to solve this problem. The proposed method is able to correct radial distortion of both areas using region adaptive distortion parameter. Each parameter is determined by considering amount of distortion in each region respectively. Also, the proposed method modifies the existing division model to correct radial distortion of both regions. Experimental results show that radial distortions in both areas are corrected.
