The keeper's note

A multi-channel motion capture tracking pattern using multiple colored shapes to improve tracking accuracy.

Abstract

A multi-channel tracking pattern is provided along with techniques and systems for performing motion capture using the multi-channel tracking pattern. The multi-channel tracking pattern includes a plurality of shapes having different colors on different portions of the pattern. The portions with the unique shapes and colors allow a motion capture system to trackmotion of an object bearing the pattern across a plurality of video frames.

Claims

1.A computer-implemented method of motion capture, the method comprising: tracking motion of an object across a plurality of video images, the object bearing a pattern having a first portion and a second portion, the first portion including a first shape and a first color and the second portion including a second shape and a second color, wherein the pattern is configured such that the first portion of the pattern is tracked based on the first shape and the first color and the second portion of the pattern is tracked based on the second shape and the second color; and causing data representing the motion of the object to bestored to a computer readable medium. 8. A system for performing motion capture, comprising: a memory storing a plurality of instructions; and one or more processors configurable to: track motion of an object across a plurality of video images, the object bearing a pattern having a first portion and a second portion, the first portion including a first shape and a first color and the second portion including a second shape and a second color, wherein the pattern is configured such that the first portion of the pattern is tracked based on the first shape and the first color and the second portion of the pattern is tracked based on the second shape and the second color; and cause data representing the motion of the object to be stored to a computer readable medium. 15. A computer-readable memory storing a plurality of instructions executable by one or more processors, the plurality of instructions comprising: instructions that cause the one or more processors to track motion of an object across a plurality of video images, the object bearing a pattern having a first portion and a second portion, the first portion including a first shape and a first color and the second portion including a second shape and a second color, wherein the pattern is configured such that the first portion of the pattern is tracked based on the first shape and the first color and the second portion of the pattern is tracked based on the second shape and the second color; and instructions that cause the one or more processors to cause data representing the motion of the object to be stored to a computer readable medium.
