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 been a program to systematically and digitally obtain the technical parameters of a certain athlete through the game video

Embodiment Construction

[0027] The present invention is described below in conjunction with accompanying drawing and specific embodiment and cooperates embodiment:

[0028] like figure 1 As shown, a badminton player's technical and tactical analysis method based on sequential pattern mining includes the following steps:

[0029] S1, video data acquisition and field coding: download the badminton game video of the athlete to be analyzed from the Internet, manually encode the action sequence of the athlete to be analyzed in the game video, and save it as a text file: including the following steps:

[0030] S101. Site marking: such as figure 2As shown, in the badminton field, the net is used as the dividing line to divide the playing field into two symmetrical X-area courts and Y-area courts; the middle line of the court is used as the dividing line to divide the court in the X-area court and the Y-area court respectively. The field is symmetrically divided into Zone 1 and Zone 2, and in the middle a...

Abstract

A badminton player's tactical analysis method based on sequential pattern mining, including: S1, video data collection and field coding, S2, manual labeling of player actions, S3, string matching for badminton technical and tactical analysis, S4, statistical output . The present invention adopts high-efficiency badminton technical and tactical encoding method to mark the input badminton game video; and then uses the character string matching method to combine the artificially marked character string data used by the players to be analyzed for each score in the collected game video with each The code of a key technique and tactics is matched and analyzed. Then judge the badminton tactics commonly used by the athlete according to the frequency of the codes of the preset key techniques and tactics appearing in the action of the athlete to be analyzed to score points. This method is helpful for badminton players to understand their own technical advantages, so as to improve their own technical and tactical level, and it is of great significance for the coaching team to conduct technical and tactical analysis before the game and summary of technical and tactical skills after the game.

Description

technical field [0001] The invention relates to the fields of video labeling, sequence pattern mining and motion 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 public. At the same time, the competitive level of high-level sports events is getting higher and higher. In order to further improve the level of professional athletes, and even provide more accurate and scientific sports data for the general public, the application of computer technology in the field of sports has become a current research hotspot. At the same time, thanks to the continuous upgrading of various hardware facilities such as high-speed camera groups, as well as the continuous deepening of sports computing, the informatization of sports has begun to develop in great strides. [0003] As a sport with a long ...
