Lastly, the method of concentric calibration is designed to realize image distortion correction.

最后采用同心圆现场标定的方法实现了图像的畸变校正。

And a satisfactory effect of fisheye image distortion correction is ultimately achieved by applying spherical coordinate orientation approach based on scans line approach.

在此基础上，采用球面坐标定位校正方法进行图像扭曲变形校正，取得了较好的图像校正效果。
