Abstract:
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.
