Vision-based weightlifting motion analysis system

The invention provides a vision-based weightlifting motion analysis system. The vision-based weightlifting motion analysis system comprises data acquisition equipment, an operation interface, an analysis module and a data storage module; the data acquisition equipment acquires front and side video data of an athlete and transmits the data to the operation interface; the operation interface displays data and transmits the data to the analysis module through a transmission protocol; the analysis module preprocesses the data through a spatial attention mechanism SAM, realizes athlete key point tracking and various exercise data analysis by using a deep neural network, and stores the data to the data storage module; and the analysis module forms an analysis report according to the key points and the motion data and transmits the analysis report to the operation interface. The operand is reduced to a great extent, the vacancy in similar applications of motion analysis is filled, and the system adopts containerized
