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 blend into the real world in terms of alignments,
perspectives, illuminations, etc. For practical reasons the information
necessary to obtain this realistic blending cannot be know a priori, and
cannot be hard-wired into a system. Instead a number of calibration procedures
are necessary so that the location and parameters of each of the system
components are known. In this paper we identify the calibration steps necessary
to build a computer model of the real world and then, using the monitor-based
augmented reality system developed at ECRC (Grasp) as an example, we describe
each of the calibration processes. These processes determine the internal
parameters of our imaging devices (scan converter, frame grabber, and video
camera), as well as the geometric transformations that relate all of the
physical objects of the system to a known world coordinate system.
