Badminton player technical and tactical analysis method based on sequence pattern mining

Abstract

The invention discloses a badminton player technical and tactical analysis method based on sequence pattern mining. The method comprises: S1, video data collection and site coding, S2, manual markingof athlete actions, S3, character string matching for badminton technical and tactical analysis, and S4, statistical output. According to the invention, an efficient badminton skill and tactical coding mode is adopted to mark an input badminton match motion video; and carrying out matching analysis on the manually marked character string data adopted by each score of the athlete to be analyzed inthe acquired competition video and the code of each key technique and tactics by utilizing a character string matching method. Then the badminton technical and tactics frequently used by the athlete is determined according to the occurrence frequency of the code of the preset key skill and tactics in the action of the score point of the athlete to be analyzed. The method is helpful for badminton players to know the technical advantages of the badminton players, so that the technical and tactical level of the badminton players is improved, and the technical and tactical analysis before and after the competition and the technical and tactical summary after the competition of coach teams are of great significance.

Problems solved by technology

As we all know, sports video information has various data types and data sizes, which leads to huge and complex data volume of sports videos.

At the same time, in the process of informatization of sports video, the connection between various technical and tactical actions in sports is often ignored, and the obtained sports information is not systematically analyzed from a higher-level perspective.

However, in the prior art, there has not yet been a program to systematically and digitally obtain the technical parameters of a certain athlete through the game video.
