Using Vision Caltech Camera Calibration toolbox for MATLAB

I am currently using the camera calibration toolbox from vision caltech:http://www.vision.caltech.edu/bouguetj/calib_doc/htmls/example.html

It has been good so far and I was able to obtain the camera parameters of my camera and everything using the checkered board.

So now I have been taking pictures with my camera and I want to undistort them using the calibration results I obtained from the caltech calibration toolbox.

The parameters are saved in a .mat file but I cannot find a way to use them on other images I took.

Anyone knows how to do that?

Thanks;

the paramaters that are output are generally the intrinsic properties of the camera, ie, the focal length, etc.... it also depends on whether it is an affine distortion or a non-linear distortion. If it is an affine distortion you would just set up a simple homography to "undistort" the image. Assuming its just a linear distortion you could just find the "undistorted" points by applying homography. Not sure if this helps, but hopefully it can point you in the right direction. – ABC

There is an easier way to calibrate cameras in MATLAB. The Computer Vision System Toolbox also includes the undistortImage function, which is what you are looking for.
