Three-Dimensional Motion Analysis System

摘要

A system for recording and displaying motion of a user includes a computer-based controller comprising a computer-readable memory and a three-dimensional motion detector that comprises a red-green-blue video camera, a depth sensor and a microphone. The system records user motion and renders the user as a three-dimensional frame comprising a plurality of joints. The joints are tracked throughout the motion and then curves representing movement of the joint(s) are displayed.

1. A system for recording and displaying motion of a user comprising:
a computer-based controller comprising a computer-readable memory; a three-dimensional motion detector responsive to said computer-based controller and comprising:
a red-green-blue video camera,a depth sensor comprising an infrared laser projector and infrared sensor; anda microphone; and a display responsive to said computer-based controller; and wherein said memory is configured with control logic adapted to cause the computer-based controller to:
receive input from said motion detector representing a video recording of the user in motion;render a three-dimensional frame representing said user, said frame comprising a plurality of joints corresponding to joints of said user;plot one or more curves representing motion of one or more joints throughout said video;store data representing said one or more curves; anddisplay an animated rendering of said one or more curves based upon said data.
