针对广角镜头数字图像产生的严重桶形畸变的问题，提出两种改进的畸变校正的算法。已有的彩色数字图像畸变校正都先将彩色图像转化为灰度图像后再进行图像的畸变校正，使得图像无法还原到原来的彩色信息。提出的非线性模型法及等效球面法直接采用原始数据图像进行校正，数字仿真实例和实验结果证明了本文算法优于已有文献的结果。
針對廣角鏡頭數字圖像產生的嚴重桶形畸變的問題，提齣兩種改進的畸變校正的算法。已有的綵色數字圖像畸變校正都先將綵色圖像轉化為灰度圖像後再進行圖像的畸變校正，使得圖像無法還原到原來的綵色信息。提齣的非線性模型法及等效毬麵法直接採用原始數據圖像進行校正，數字倣真實例和實驗結果證明瞭本文算法優于已有文獻的結果。

Aiming at the serious barrel distortion problem of wide-angle lens digital image,this paper put forward two Improved Distortion Correction Algorithms.The distortion Correction Algorithms in literature are divided into two steps:the first step is to change color image to grayscale,and the second step is to correct image distortion,but these methods can 't restore the original color information of image.The nonlinear model method and equivalent spherical method proposed in this paper use the original data of image.The numerical simulation examples and experiment results were given to illustrate the superiority of the obtained results to those in literature.
