Abstract
A motion-capture system is provided. The motion-capture system includes a host computing system and a plurality of motion-capture cameras that are operatively coupled with the host computing system. Each of the motion-capture cameras is disposed in a different location and orientation relative to a motion-capture space and includes a marker-tracking optical filter to provide a marker-tracking mode and thereby relatively enhance light from markers on a moving body in the motion-capture space. One or more of the motion-capture cameras is remotely controllable to selectively interchange the marker-tracking optical filter with a scene-view optical component, so as to selectively transition the motion-capture camera between the marker-tracking mode and a scene mode, in which light from the markers is less enhanced than in the marker-tracking mode.
