Wide angle lenses calibration with Opencv

Question

I\'m using a wide-angle lens (178º Diagonal FOV ) and I\'m trying to calibrate it properly using Opencv Calibration module. All the detection and calibration process are working

Answer 1

Since Opencv 2.4.10 and above there is a specfic distortion model for wide-angle/fisheye lenses able to handle this strong radial distortion. I've tested with my datasets and results are very good.
