鱼眼相机去畸变c++

opencv c++库中的三个库函数给出的结果如右上，表现为球体，疑似还原回鱼眼相机的原始状态，需要转换思路至拉直图像中的线条，参考：https://stackoverflow.com/questions/45459088/reverse-fisheye-radial-distortion-using-field-of-view-model

但matlab可以给出线条直平的图。

根据StackOverflow，

opencv的鱼眼模型为Generic Camera Model by Juho Kannala and Sami S. Brandt.

而MATLAB为 The Scaramuzza model used by MATLAB

两者内参混用需转换。

畸变参数的本质：the distortion coefficients that describe the distortion caused by the lens are typically represented as a set of polynomial equations that describe the relationship between the distorted and undistorted image coordinates.
