Abstract:
We present a method to analyze the sprinter's form in 100 m sprint races. To achieve good time records, sprinters should know the problem on their sprint form, for example, by analyzing the difference between good and bad forms. The proposed method captures two performance videos at different points (e.g., 50 and 90 m) in one 100 m sprint race, and matches them frame‐by‐frame to compare the two sprint forms. The method calculates the sprint motion similarity from body keypoints, and then matches video frames focusing on the periodicity of sprint motion and the linearity of sprint speed. We conducted experiments with performance video pairs for six sprinters, and confirmed that the proposed method could match them accurately, which showed the effectiveness and the usefulness of the method. Also, the coach of our track‐and‐field team could find some improvements of the sprinters by referring to the outputs of the method. © 2021 Institute of Electrical Engineers of Japan.
