Abstract
A system, apparatus and method are described for improving marker identification within a motion capture system. For example, a system according to one embodiment of the invention comprises: a plurality of cameras configurable for a motion capture session, each of the cameras having an illuminating device for generating light and a lens for capturing light reflected off of one or more retro-reflective markers used for the motion capture session; and a plurality of pieces of polarized material coupled over the illuminating device and the lens of each of the cameras, wherein for each individual camera, either a first orientation or a second orientation for the polarized material is selected based on which other cameras are within the individual camera's field of view and the orientation of the polarized material used for the other cameras, the first orientation being perpendicular to the second orientation.
