Abstract
The present invention is directed to a method and apparatus for providing three-dimensional (3-D) input data to a computer. A marker is moved in a 3-D work place. The marker has at least one unique feature distinctive from other objects in the 3-D work place. The movement of the marker in the 3-D work place is sensed by at least two sensors in a stereo imaging geometry to produce stereo images containing the marker. The stereo images are processed to produce marker images. The 3-D coordinates of the marker are computed from the marker images to provide the 3-D input data to the computer.
