A method (200) for capturing and analyzing user actions is provided. The method (200) comprises capturing an action of a first user represented by RGB moving images and depth data (step A), acquiring 2D bone data from the RGB moving images of each frame (step B), converting the 2D bone data into 3D bone data by mapping the 2D bone data with the corresponding depth data of each frame (step C), determining one or more key postures of the action of the first user according to a preset condition of each key posture (step D), acquiring one or more key postures of the action of the first user and segmenting the action sequence into segments through the key postures (step E); each segment is sampled and aligned with a respective segment of a set of standard key gestures (step F), and trajectories obtained from the aligned segments between the one or more key gestures of the action of the first user and the set of standard key gestures are compared (step G). 提供了一种用于捕捉和分析用户动作的方法(200)。该方法(200)包括捕捉由RGB移动图像和深度数据表示的第一用户的动
