The camera calibration toolbox for Matlab (version 3.0) utilizes a new bias correction procedure for circular control points and a nonrecursive method for reversing the distortion model. To learn more about the calibration method see .
The toolbox is freely available, and you can download it from here:
(103 k) or
calibr_v30.zip (32 k)
For more information about installation, see the README file.
The first version of the toolbox was released in Sept. 1996. For downloading
