Abstract :
Describes a prototype of an augmented reality system using vision-based registration. In order to build an augmented reality system with video see-through image composition, camera parameters for generating virtual objects must be obtained at video-rate. The system estimates camera parameters from four known markers in an image sequence captured by a small CCD camera mounted on a HMD (head mounted display). Virtual objects are overlaid upon a captured image sequence in real-time
