Abstract

Computer systems are increasingly being used for sports training. 
Existing sports training systems either require expensive 3D 
motion capture systems or do not provide intelligent analysis of 
user's sports motion. This talk presents a framework for affordable 
and intelligent sports training systems for general users that 
requires only single camera to record the user's motion. Sports
motion analysis is formulated as a 3D-2D spatiotemporal motion 
registration problem. A novel algorithm is  developed
to perform spatiotemporal registration of the expert's 3D reference 
motion with a performer's 2D input video, thereby computing the 
deviation of the performer's motion from the expert's motion. The 
algorithm can effectively handle ambiguous situations in a single 
video such as depth ambiguity of body parts and partial occlusion.
Test results show that, despite using only a single camera, the 
algorithm can compute 3D posture errors that reflect the 
performer's actual motion error.
