Patent ID: 8670029

Claim:
A camera motion capture system, comprising: a 3-D depth camera comprising an illuminator and an image sensor, the illuminator comprises: (i) at least one superluminescent light-emitting diode outputting light at a near infrared wavelength and at a power level of at least 75 milliwatts, (ii) a collimating lens which captures the light from the at least one superluminescent light-emitting diode to provide a collimated light beam, and (iii) a diffractive optical element which receives the collimated light beam; and creates a plurality of diffracted light beams which define a field of view, the field of view extends in a sufficiently wide angle, in height and width, to illuminate an entire height and width of a human target while the human target moves around in a floor area when interacting with an application of the motion capture system; and the image sensor senses reflected light from the human target in the field of view and creates a depth image of the human target using the reflected light from the field of view; and at least one processor associated with the image sensor, the at least one processor tracks movement of the entire height and width of the human target in the floor area using the depth image.
