Generation of light for tracking and acquisition of three-dimensional scene geometry in computer graphics applications

Methods, systems and computer products are provided for tracking objects within a scene using imperceptible structured light. The imperceptible structured light may be used in environments where humans work and therefore avoids disorienting observers. The structured light patterns are generated dyna...

More Information
Summary:Methods, systems and computer products are provided for tracking objects within a scene using imperceptible structured light. The imperceptible structured light may be used in environments where humans work and therefore avoids disorienting observers. The structured light patterns are generated dynamically, allowing tracking without physical landmarks. Moreover, the occlusion of the generated landmarks is overcome by determining the position of objects using a determined camera position. The imperceptible structured light may be used in systems without tracking. The tracking may be used without imperceptible structured light.
