It is important to analyze a service in table tennis, and the number of rallies is used as an indicator for the service analysis. An analyzer requires watching all of the target match videos to record the number of rallies. This paper proposes a method for measuring the number of rallies in table tennis videos. We assume that the rally in the video is taken in a vertical setting. Our method detects hit balls passing through the upper court to measure the number of rallies, and the other hit ball that does not pass through the upper court is interpolated from the direction of the hit balls before and after detection. In addition, the number of rallies is used to calculate the score ratio and loss ratio. Experimental result showed that the proposed method correctly counted the number of rallies in 90.2~¥% of 623 scenes of Japanese T-League match videos. |
