Claim 7:
8. The method of claim 7, wherein
the estimating of a posture of a training tool comprises:
matching the center point of the depth information included in the obtained data with the center point of the IR data obtained from the IR marker attached to the training tool;
extracting pixels having depth data in each direction above, below, left, and right from the depth information based on the matched center point;
converting the positions of the extracted pixels into three-dimensional positions;
determining a three-dimensional position of a pixel having an average value of the three-dimensional positions of the extracted pixels as a position of the IR marker; and
estimating the posture of the training tool based on the determined position of the IR marker.
