Rehearsal Path Method: A Marker-less Camera Tracking Method Aiming for Robustness to the Real World(<Special issue>Real World Imaging)

Abstract

This paper describes a high-performance camera tracking method for filmmaking under the certain restriction on the camera path. The proposed method called "rehearsal path method" realizes real-time geometric registration using a landmark database which was constructed in advance. Furthermore, the rehearsal path method has three efforts against two actual problems of marker-less tracking methods: (1) the case of wide scene, and (2) the case of scene which has unstable feature points such as trees. Finally, some experimental results were shown in order to confirm and discuss convenience of use and performance improvement.
