Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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.
