Apparatus and method for performing motion capture using a random pattern on capture surfaces
A method is described comprising: applying a random pattern to specified regions of an object; tracking the movement of the random pattern during a motion capture session; and generating motion data representing the movement of the object using the tracked movement of the random pattern.
1. A method comprising:
distributing particles across the surface of a liquid so as to create a random pattern;
capturing sequences of images of the random pattern with a first plurality of cameras as the liquid moves during a motion capture session;
correlating on a computing device the random pattern across two or more images captured from two or more different cameras to create a 3-dimensional surface of a specified region of the liquid; and
generating motion data on the computing device representing the movement of the 3-dimensional surface of the liquid in the specified region of the liquid, using the sequence of images.
2. The method as in claim 1 wherein the particles are phosphorescent.
3. The method as in claim 1 wherein the particles are retroreflective.
4. The method as in claim 1 wherein light emissions from the particles are visible with high contrast compared to the light emissions of the liquid when captured.
