摘　　要：文章通过对基于双线性插值算法的鱼眼镜头校正算法进行分析。从鱼眼镜头成像的基本原理以及成像的光学性特点进行分析,在此基础上对鱼眼镜头成像畸变原来与校正流程进行归纳总结,从常见的图像插值算法进行分析图像校正的过程,并运用三种方法即最近点插值法、双线性插值、双三次插值三种方法进行对比分析,最后根据双线性插值算法的最优性,校正后图像有明显的改善,图像更加清晰。Based on the fisheye correction algorilhm based on bilinear interpolation algorithm is analyzed. From the analysis ofthe basic prin-ciple of fisheye lens imaging and optical imaging characteristics, on the basis of the origmal fisheye lens imaging distortion are summarized and correction process, by analyzing the process of image correction from tiie common image interpolation algorithm, and the use of three methods： the nearest point interpolation, bilinear interpolation, double three interpolation three methods were compared and analyzed, finally, based on the optimality of bilinear interpolation algorithm, the corrected image is improved obviously, the image is more clear.
