Abstract

An optical tracking system comprising a main camera, an optical tracking camera, a light source, and one or more markers that are configured to engage an LED wall without impeding the light generated by the LED wall so that the optical tracking camera can identify its own location in three dimensional space, and by extrapolation, the location in three dimensional space of the main camera.

Claims (17)

1 . An optical tracking system, comprising:

a main camera;

an optical tracking camera;

a light source;

one or more markers;

wherein said optical tracking camera is fixed relative to said main camera;

wherein said light source is configured to emit light into the field of view of the optical tracking camera;

wherein said one or more markers are visible to said optical tracking camera;

wherein said one or more markers are not visible to said main camera;

wherein said one or more markers comprise a retroreflective surface;

wherein said one or more markers comprise one or more holes; and

wherein said markers are configured to be affixed to an LED wall such that said one or more holes are configured to allow light generated from said LED wall to pass through said one or more holes of said one or more markers without interference.

2 . The optical tracking system of claim 1 , wherein the optical tracking camera comprises an optical filter that is configured to attenuate or block all wavelengths of light except a band of wavelengths around a wavelength emitted by the light source.

3 . The optical tracking system of claim 1 , wherein the optical tracking system is synchronized to the main camera such that the exposure times of the optical tracking camera and the main camera do not substantially overlap.

4 . The optical tracking system of claim 1 , wherein said one or more markers comprise a first marker and a second marker;

wherein said first marker and said second marker engage different parts of said LED wall.

5 . The optical tracking system of claim 1 , where each of said one or more holes of said one or more markers is sized and positioned on said LED wall to allow one LED of said LED wall to pass through each of said one or more holes.
