Camera Calibration Toolbox for Matlab
In addition to the window ">calibration application implemented in C, we provide a
Matlab® implementation of the
algorithm together with its complete documentation. This document may
also be used as a tutorial on camera calibration since it includes
general information about calibration, references and related links.

System requirements
This toolbox works on Matlab 5.x (up to Matlab 5.3) on Windows, Unix
and Linux systems (platforms it has been fully tested) and does not require
any specific Matlab toolbox (for example, the optimization toolbox is not
required). The toolbox should also work on any other platform supporting
Matlab 5.x.
Getting started
Download the complete
camera calibration toolbox for Matlab in the format of your choice: HREF="javascript: getDownload();">TOOLBOX_calib.tgz (61Kb
tar-gzipped) or getDownload();">TOOLBOX_calib.tar (280Kb tar) or HREF="javascript: getDownload();">file by file (last update: 15-May-2000).
Store the individual matlab files (.m files) into a unique
folder TOOLBOX_calib (default folder name). Run Matlab
and add the location of the folder TOOLBOX_calib to the main
matlab path. This procedure will let you call any of the matlab
toolbox functions from anywhere. Under Windows, this may be easily
done by using the path editing menu. Under Unix or Linux, you may use
the command addpath.
Run the main matlab calibration function calib_gui. The main calibration toolbox window appears on the screen:
You are now ready to use the toolbox for calibration.
Calibration examples
First calibration example - Corner extraction, calibration, additional tools
This section takes you through a complete calibration example based on
a total of 20 (and 25) images of a planar checkerboard. This example
lets you learn how to use all the features of the toolbox: loading
calibration images, extracting image corners, running the main
calibration engine, displaying the results, controlling accuracies,
adding and suppressing images, undistorting images, exporting
calibration data to different formats... This example is highly
recommended for someone who is just starting using the toolbox.
Second calibration
example - Calibration using Zhengyou Zhang's data
This section shows you how to use the main calibration engine on
Zhengyou Zhang's data in a scripting mode. After going through that
example, you will also know how to change the intrinsic camera model by
choosing which parameters to optimize. This example is highly
recommended for someone who intends to use the main calibration engine
in their own matlab script files.
Third calibration
example - Calibration using Heikkil
