This disclosure provides techniques of implementing online somatosensory dance competitions. The techniques comprise assigning a room to one or more players in response to receiving one or more requests of starting a game, wherein all players in a same room share a same dance video; outputting a plurality of standard movement images corresponding to the same dance video in a chronological order, wherein the plurality of standard movement images each indicate position coordinates of different skeleton nodes at a corresponding moment; receiving dance movement signals associated with each of the one or more players, and determining scores for each player based on a similarity between the dance movement signals and standard movement parameters, wherein the standard movement parameters correspond to the standard movement images; and collecting and outputting statistics on an overall score and ranking of each of the one or more players.

Online somatosensory dance competition method and apparatus, computer device, and storage medium

This disclosure provides techniques of extracting movements from a dance video. The techniques comprise receiving a dance video that includes one or more dancers and that is uploaded by a user, and obtaining a video frame in the dance video; recognizing, based on a skeleton node recognition algorithm, skeleton node images from the video frames corresponding to a target dancer, where the target dancer is selected from the one or more dancers; performing cluster analysis on the skeleton node images recognized from the dance video and corresponding to each target dancer to obtain a plurality of cluster sets; determining a cluster center in each of the plurality of cluster sets as a key skeleton node image; and sequentially outputting the key skeleton node images to obtain a standard movement sequence corresponding to each target dancer in the dance video.
