Abstract
The present invention provides a method and system for resolving complete free space orientation of an active receiving device at high speed using simple optics, trigonometry, simple circuitry, and using minimal processing power. The rapid triangulation of distance from the emitters, as well as resolution of rotational orientation, are determined by changing the contrast level in an infrared spectrum and by using wide angle lenses with greater than 180 degree hemispherical viewing angles. Furthermore, the system consists of an optional accelerometer, resident on the receiver, to dynamically adjust the image sensor frame rate.
