A method and an apparatus for detecting key points of a human body, and a storage medium are provided. The method includes: extracting, in response to detecting that an image comprises a body, two-dimensional (2D) coordinate data for identifying body keypoint positions in the image to obtain 2D pose data; and performing body keypoint feature fusion on the 2D pose data and depth data corresponding to the body keypoint positions to obtain three-dimensional (3D) pose data for identifying the body keypoint positions.
