Object Calibration for Augmented Reality

Ross T. Whitaker, Chris Crampton, David E. Breen, Mihran Tuceryan and Eric Rose, "Object Calibration for Augmented Reality", Computer Graphics Forum (Proc. Eurographics '95), Vol. 14, No. 3, pp. 15-27, August 1995.

Augmented reality entails the use of models and their associated renderings to supplement information in a real scene. In order for this information to be relevant or meaningful, the models must be positioned and displayed in such a way that they align with their corresponding real objects. For practical reasons this alignment cannot be known a priori, and cannot be hard-wired into a system. Instead a simple, reliable alignment or calibration process should be performed so that computer models can accurately represent their real-life counterparts. We describe the design and implementation of such a process and we show how it can be used to create convincing interactions between real and virtual objects.
