Abstract
A performance capture system is provided to detect one or more active marker units in a live action scene. Active marker units emanate at least one wavelength of light that is captured by the performance capture system and used to detect the active markers in the scene. The system detects the presence of the light as a light patch in a capture frames and determines if the light patch represents light from an active marker unit. In some implementations, various active markers in a scene may emanate different wavelengths of light. For example, wavelengths of light from multi-emitting active marker units may be changed due to various conditions in the scene.
