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.

Embodiment Construction

[0025] The present invention will be described below in conjunction with the drawings and specific implementations and with examples:

[0026] Such as figure 1 As shown, a technique and tactical analysis method of badminton players based on sequential pattern mining includes the following steps:

[0027] S1. Video data collection and venue coding: download the badminton game video of the athlete to be analyzed from the Internet, manually code the action sequence of the athlete to be analyzed in the game video, and save it as a text file: including the following steps:

[0028] S101. Site marking: such as figure 2 As shown, in the badminton arena, the net is used as the dividing line, and the arena is divided into two symmetrical areas X and Y; the center line of the arena is used as the dividing line, respectively in the X area and Y area. The field is symmetrically divided into zone 1 and zone 2, and the middle and back field is symmetrically divided into zone 3 and zone 4. Take th...

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.

Description

Technical field [0001] The invention relates to the fields of video tagging, sequence pattern mining, and sports analysis, in particular to a method for analyzing techniques and tactics of badminton players based on sequence pattern mining. Background technique [0002] With the development of the times, sports are becoming more and more popular among the general public. At the same time, the competitive level of high-level sports events is getting higher and higher.
