【摘要】 把鱼眼图像变成透视投影图像,球面投影和抛物面投影是常用的方法,而这两种方法处理的都是有效区域为圆形的鱼眼图像。为了更加有效利用现有的矩形CCD成像面,现如今国外一些镜头公司推出一种新型的鱼眼镜头,其特征为其拍摄的鱼眼图像的有效区域为椭圆形,并且其镜头视角为全视角且视角可以超过180度,在只给出若干幅此种镜头拍摄的鱼眼图像,未给出镜头以及镜头参数的情况下如何对已有的鱼眼图像进行快速的畸变校正,本文将提供这样一种方法。更多还原

【Abstract】 Transform the fish eye image into a perspective projection image,projection and a circular parabolic projection is commonly used method,which mainly deal with the circular fish-eye images,.The lens for some foreign companies are now introduced some new fish-eye lens,characterized by a 180-degree viewing angle generated when the oval-shaped fish-eye image.And its angle can exceed 180 degrees,Single-only fish-eye images are given and a given camera perspective,without giving the camera lens and the unknown model parameters.In that case,HowOn the existing fish-eye image distortion correction,this article will provide such an approach.更多还原
