基于柱面模型的鱼眼影像校正方法的研究

鱼眼镜头突破普通相机对视场的限制，然而它存在畸变。从基于球面透视的柱面模型出发，介绍如何对整幅鱼眼影像进行畸变校正，提出一种基于球面透视的柱面模型的等弧长映射方法，并给出具体算法的推导，实现了对鱼眼影像畸变的校正，取得了较好的效果。

Study on fisheye image correction based on cylinder model

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.
