Study on fisheye image correction based on cylinder model
基于柱面模型的鱼眼影像校正方法的研究

Fisheye lens break the limit on the view field of the ordinary camera, and develop a new path for computer vision research and application. In spite of its advantage in broader view and importance in application, fisheye image has its own distortion. A way to correct the distortion of the whole fisheye image was introduced. A method called equal arc length mapping in cylinder model based on the spherical perspective was proposed to solve the problem of distortion. The specific derivation of the algorithm was also provided. The obtained images prove the effectiveness of the proposed algorithm.
