Development of 3D Positioning Scheme by Integration of Multiple Wiimote IR Cameras

摘要

A Wiimote 3D localization scheme has been developed for smart living or computer animation applications. This scheme utilizes a pair of Wiimotes to form a stereo vision and a kinematics relation is established to extract the 3D position of objects by using geometric transformation. However, due to the limitation in pixel resolution, the positioning resolution deteriorated at larger sensing distance. Therefore, a dual Wiimotes 3D scheme is also proposed for further improving the performance at the foundation of the single Wiimote 3D localization. By adding another Wiimote pair at the opposite side, we can expand the positioning range and reduce the positioning error with larger sensing distance. The experimental results indicate that this scheme is effective in achieving the above mentioned goals. With properly integration with this scheme, It is expected that applications such as positioning of indoor mobile robots and human motion capture for animations could achieve a better performance.
