Claim 17:
18. The apparatus of claim 17, wherein
when performing the operation of estimating a posture of a training tool, the processor is configured to perform operations by:
matching the center point of the depth information included in the obtained data with a 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 the position of the IR marker; and
estimating the posture of the training tool based on the determined position of the IR marker.
