• Abstract:

  The routine athlete motion data space trajectory retrieval method can track the trajectory of athletes' movements. However, when the detailed space trajectory retrieval is performed on the athletes' hopping movements, there is a lack of retrieval ability. To this end, the research on spatial trajectory retrieval method of athletes' tread motion data is proposed. Based on the extraction of the athlete's stepping action feature information, the R-Tree and its variant spatial index are determined, and the spatial trajectory retrieval model of the athlete's stepping motion data is constructed. Using the data space trajectory index design of the athlete's stepping motion data, the spatial trajectory retrieval result is output, and the spatial trajectory retrieval method of the athlete's stepping motion data is completed. The experimental data shows that the proposed trajectory retrieval of athletes' hopping movements is more than conventional trajectory retrieval, and the retrieval ability is improved by 53.41%, which is suitable for detailed spatial trajectory retrieval of athletes' hopping movements.
