Multi-person Virtual Rehearsal System Based on Optical Location Tracking

Rehearsal system is the latest form of 3D technology applications in the field of film and television. In this paper, we propose a novel multi-person virtual rehearsal system based on passive optical motion capture technology. A new fast location algorithm for human motion gesture is presented, which combines the traditional forward kinematic algorithm with the location tracking algorithm of markers, and uses noise elimination filter method and Euclidean distance to stability and evaluation of markers data. The experimental result shows that this system, focusing on the interaction of actors and scenes, lights, cameras, etc, could realize the shooting test and scene rehearsal of VR films well with high capture precision, tracking stability and real-time performance, and improving the efficiency and quality of VR films greatly.
