Abstract
A hybrid system which detects and tracks objects in three-dimensional space using a light source disposed in spaced relation to a projection surface, defining a volume of space illuminated by said light source. A light sensor responsive to illumination falling on the projection surface measures illumination levels over a predefined image plane associated with the light sensor, producing a projected image signal. A structured light source projects a structured light within the volume of space and a structured light sensor records reflected structured light from objects occupying the volume of space producing a structured light signal. A correlation processor receptive of the projected image signal and said structured light signal and adapted to compute a hybrid signal indicative of the position of an object within said space and from which other information about the object may be extracted.
