AUTOMATED SCORING SYSTEM FOR ATHLETICS
First Claim
1. A method of evaluating a subject'"'"'s performance comprising:
- receiving a sequence of images as the subject moves through a defined space;
processing, by a processing device, the sequence of images to generate a performance model corresponding to the movement of the subject through the defined space;
comparing, by the processing device, the performance model with a comparison model;
identifying, by the processing device, deviation between the performance model and the comparison model; and
outputting, by the processing device, the identified deviation in a human or machine readable format.

Abstract
Disclosed are methods and systems for utilizing motion capture techniques, for example, video based motion capture techniques, for capturing and modeling the captured 3D movement of an athlete through a defined space. The model is then compared with an intended motion pattern in order to identify deviations and/or form breaks that, in turn, may be used in combination with a scoring algorithm to quantify the athlete'"'"'s execution of the intended motion pattern to produce an objective score. It is anticipated that these methods and systems will be particularly useful for training and judging in those sports that have struggled with the vagaries introduced by the subjective nature of human scoring.

8. A system for evaluating a subject'"'"'s performance comprising:
-
a camera array arranged and configured for capturing a plurality of image sequences of the subject in a defined space; a processor arranged and configured for converting the captured images sequences into a performance model corresponding to the subject'"'"'s motion through the defined space; identifying a deviation between the performance model and a comparison model; and assigning a deviation value to the deviation. - View Dependent Claims (9, 10, 11, 12, 13)
