Figure 1: GML Camera Calibration toolbox v. 0.7 supports multiple calibration patterns within one project. During the calibration a relative orientation between pattern coordinate systems is recovered. Our experiments show the usage of multiple patterns makes the calibration procedure more stable and impoves calibration accuracy. Also less images for calibration are needed.

GML Camera Calibration toolbox is a free functionally completed tool for cameras' calibrating. You can easy calculate intrinsic and extrinsic camera parameters after calibrating. This software uses a as a calibration pattern. The calibration process is completely automatic. There are two chessboard detection algorithms in all.

GML Camera Calibration toolbox 0.7 supports multiple calibration patterns within one project. During the calibration a relative orientation between pattern coordinate systems is recovered. The usage of multiple patterns makes the calibration procedure more stable, this impoves calibration accuracy and less images for calibration is needed.

GML Camera Calibration toolbox 0.7 (beta) was released on 18.11.2011. Your Feedback is appreciated!
The code was written for OpenCV 2.1 and was tested mostly on win32 (Windows XP, Windows Vista, Windows 7) platform. System Requirements: .Net Framework 3.5 SP1
Please read our recommendations for taking calibration photos before starting a calibration procedure.
We extend our gratitude to Chibunitchev A., whose help was significant in creation of this toolbox.
