Camera Self-Calibration for the ARToolKit
Camera calibration is an essential and important part of an Augmented Reality (AR) system. The use of a planebased calibration technique can give a good accuracy, which can be important for AR applications. The calibration technique used in the current ARToolKit requires user intervention, which is prone to error and involves a lengthy calibration time. The camera has to be recalibrated every time the focal length changes which is cumbersome and less suitable for applications where a more automated and easier approach is needed. This paper investigates the use of camera self-calibration for the ARToolKit, which has the advantage of simplicity of implementation. In order to improve its accuracy, a distortion model is also investigated. In this context several interesting results are presented.

Abstract

Camera calibration is an essential and important part of an Augmented Reality (AR) system. The use of a planebased calibration technique can give a good accuracy, which can be important for AR applications. The calibration technique used in the current ARToolKit requires user intervention, which is prone to error and involves a lengthy calibration time. The camera has to be recalibrated every time the focal length changes which is cumbersome and less suitable for applications where a more automated and easier approach is needed. This paper investigates the use of camera self-calibration for the ARToolKit, which has the advantage of simplicity of implementation. In order to improve its accuracy, a distortion model is also investigated. In this context several interesting results are presented.
