Abrégé

A system and method are described for performing motion capture on a subject using transparent makeup, paint, dye or ink that is visible to certain cameras, but invisible to other cameras. For example, a system according to one embodiment of the invention comprises the application of makeup, paint, dye or ink on a subject in a random pattern that contains a phosphor that is transparent in the visible light spectrum, but is emissive in a non-visible spectrum such as the infrared (IR) or ultraviolet (UV) spectrum; using visible light such as ambient light or daylight to illuminate the subject; using a first plurality of cameras sensitive in the visible light spectrum to capture the normal coloration of the subject; and using a second plurality of cameras sensitive in a non-visible spectrum to capture the random pattern.

A system and method are described for performing motion capture on a subject. For example, a computer-implemented method according to one embodiment of the invention comprises: creating a scalar field for the three- dimensional (3-D) capture volume of the subject; generating a surface mesh for the scalar field; retaining good vertices and removing bad vertices of the surface mesh; and storing the good vertices for use in subsequent reconstruction of the motion of the subject. Another computer-implemented method comprises: capturing a series of image frames of the subject over a period of time each frame each frame having a plurality of vertices defining a captured surface of the subject; establishing a reference frame having one or more of the plurality of vertices; performing frame-to-frame tracking to identify vertices within the N'th frame based on the (N-1 )'th frame or an earlier frame; and performing reference- to-frame tracking to identify vertices within the N'th frame based on the reference frame to counter potential drift between the frames. Yet another computer- implemented method comprises: capturing motion capture data including a plurality of images of the N vertices during a motion capture session; retrospectively identifying X of the N vertices to track across the plurality of images where X < N; and tracking the X vertices across the plurality of images.
