Stereo Camera Tracking for Mixed Reality-Based PreViz of Stereoscopic 3D Cinema Using ICP Algorithm

This paper presents a method of real-time 6-DOF stereo camera tracking using ICP algorithm used in our mixed reality based previsualization (PreViz) system for stereoscopic 3D filmmaking. We eliminate the time-consuming preparation processes required for improving the accuracy in our previous work. On the assumption that the camera repeatedly passes along a path roughly determined at the rehearsal, multiple maps is created along the path using stereo vision technology and is continuously added and refined during a PreViz shooting. Experiments with real data in a miniature set and full scale set for filmmaking were conducted.
