Abstract

The invention discloses an intelligent interactive data collection system for a table tennis match video. The system comprises (1) a hot start module which comprises buttons or input boxes of varioustypes of basic information, and enables a user to mark and input the basic information of the match video in an interactive mode; (2) a match guide module which comprises a bureau list, a round list and a shot list and is used for organizing and guiding match video clips of a match and helping a user to efficiently locate to a target round; (3) a video annotation and verification module which comprises a match video embedded with interactive visual elements and generates accurate match data through interaction; and (4) a rear-end calculation module which realizes real-time updating of data through interaction with other modules. According to the system, the accuracy of data annotation and the efficiency of data collection are improved; and the match guide is associated with the match video, so that quick positioning of the video clip is realized.

Description

technical field [0001] The invention relates to the field of ball game data collection, in particular to an intelligent interactive data collection system for table tennis game videos. Background technique [0002] In the past forty years, the national table tennis team has tried to label the data. These methods have evolved from counting markers to video editing software and then to tailor-made interactive annotation tools. Although these attempts have improved the efficiency of data collection to some extent, there are still challenges to effectively obtain high-quality, fine-grained data. Therefore, intelligent methods that can significantly improve the efficiency of data annotation are highly desired. However, there are two main challenges to automating data collection: [0003] Low quality broadcast video. During most table tennis matches, only television cameras are installed, and only broadcast video is available for analysis. Even if advanced equipment can be de...
