DEVICE AND METHOD FOR CAPTURING AND ANALYZING A MOTION OF A USER

A method for capturing and analyzing a motion of a user includes capturing a motion of a user represented by an RGB moving image and depth data, obtaining 2D skeletal data based on the RGB moving image, converting the 2D skeletal data to 3D skeletal data by mapping the 2D skeletal data with corresponding depth data, determining one or more key poses of the motion of the user based on a preset condition for each of the key poses, obtaining the one or more key poses of the motion of the user and segmenting a motion sequence by the key poses into segments, sampling each segment and aligning each segment with a corresponding segment of a set of standard key poses, and comparing trajectories obtained based on the aligned segments between the one or more key poses of the motion of the user and the set of standard key poses.
