ABSTRACT:
A system for determining the spatial position and angular orientation of an object in real-time is provided having a sensor section and a plurality of activatable markers, adapted for mounting to the object. The plurality of markers are activated simultaneously during each cycle of the sensor section after an initial marker-identification mode and energy emitted by such simultaneously activated markers is detected by the remotely located sensor. With such system, because the markers have been each uniquely identified during the marker-identification mode, and the relative marker geometry is known a prior, the markers can be simultaneously activated, detected and tracked during a subsequent marker-tracking mode. With such an arrangement, less expensive sensors with relatively low sensor cycle rates may be used.
