To solve theforce-posturesynchronization problem in the digital shot system without disturbing the normal training,a non-invasive data-image synchronization method based on image features is proposed.The key frame of shot-putting is judged by the roundness feature after the high-speed image sequences captured,and the approaches such as ROI setting and key frame predicting are employed to improve the algorithm efficiency for real-time high-speed and high-resolution processing.Then the influence of parameters setting on algorithmic efficiency is analyzed comparatively in experiments.The experimental results show the synchronization accuracy can reach 93.1%,which meet the needs of auxiliary training effectively.
