I want to convert my fisheye camera images to normal one, also I tried using MATLAB but didn't worked.Can anybody tell how to dewarp it or how can I find undistorted images using matlab camera calibration.

@Bjorn Gustavsson currently I am using airglow images, could you provide more information about this tool and how it works (some reference)

Thanks in advance

Hello Sivakandan,

during my PhD-work I developed geometric calibration-tools for the Auroral Large Imaging System (a multi-camera network with the ambition to do 3-D imaging of the aurora over the Kiruna region in Sweden). For this I used the known positions of stars in the sky to calibrate the lines-of-sight of the cameras. If you are interested you can find my thesis here:

Three dimensional imaging of aurora and airglow

...and the documentation of the camera-calibration and image processing tools here:

AIDA: Auroral Image Data Analysis tools

AIDA_tools have since been updated and upgraded, but you should be able to get the gist of what it provides from this. The toolbox contains all sort of spatial image-analysis tools for aurora and airglow analysis. However, it builds on my more general camera-models instead of the standard pinhole (with distortion-addons) models provided by matlab and other standard tools.
