Fitness action scoring method, system and device based on spatio-temporal information

The invention discloses a fitness action scoring method, system and device based on spatio-temporal information. The method comprises the steps of collecting video information in real time and uploading the information in a video stream transmission mode; preprocessing the real-time video information according to frames; carrying out key skeleton point extraction on the preprocessed frame image; scoring based on time sequence information and space geometric information in the two-dimensional skeleton point sequence; and performing score correction on the original score result. The system comprises an acquisition module, a preprocessing module, an extraction module, an original scoring module and a score correction module. The device comprises a memory and a processor used for executing the fitness action scoring method based on the spatio-temporal information. By using the method, the actions of the fitness user can be scored in real time, the detection speed is high, and the result is reliable. The fitness a
