Abstract
According to an embodiment, a system comprises a target image display forming a skeleton image of a subject on a grid pattern with a predetermined unit length and coordinates via image processing by a three-dimensional (3D) depth camera, specifying, on the skeleton image, feature points corresponding to the subject's joints, a reference point corresponding to a measurement target among the feature points, and a motion point corresponding to a joint moving with respect to the reference point, and generating a connection line connecting the feature points and an information processor obtaining the body information from the skeleton image using the feature points, the connection line, the grid pattern, and a gravity line and median line of the subject, evaluating the posture information according to a preset posture classification criterion, and measuring the joint motion range by tracking motion of the motion point with respect to the reference point.
