Problems solved by technology

Based on the game video, people can extract and summarize the semantic events in the video, and can extract and display the cooperation events, but the display form is relatively obscure, and some information will be missing at the same time, and the details of the cooperation between players cannot be effectively displayed. ; By comparing and processing the patterns in the game history information, people can explore and study the team's tactics, but the display method is not very intuitive, and users cannot clearly understand the cooperation pattern; As a node, pass the ball as a connection, thus connecting the teams as a network, but the scoring information cannot be effectively displayed
[0005] At present, there is still no method that can intuitively and effectively display coordination information, and at the same time study the team's tactical system based on coordination model modeling

example 1

[0042] Example 1. Analysis of player coordination in a single game

[0043] According to the method and steps of the present invention, a visual design diagram (such as Figures 1 to 5 shown), each player is represented by a sector with different gray levels, and each player contains an assist sector (the assist score is represented by "player name_ast" in the figure) and a scoring sector (the score is represented by The "player name_score" indicates), the former indicates the situation of assisting teammates to score, and the latter indicates the scoring situation of receiving teammates' assists, such as figure 1 , figure 2 shown.

[0044] Will figure 2 Heat shown and figure 1 Compared to the Bulls shown, this visualization resolves to: Heat

[0045]Inside players score less. The Heat's three inside players Bosh, Haslem and Anderson scored only 31 points in total; while the Bulls' inside player Boozer scored 31 points alone, and the other scored 31 points. A main ins...

example 2

[0048] Example 2. Analysis of player cooperation mode based on historical data

[0049] Select the players of the Heat team to analyze the cooperation mode. Considering that there may be accidental errors in the data of a single game, the match records of the Heat team and 29 other teams in the season are selected as the data support. If player A and player B cooperate well If there are many, the distance between the two parties in the multidimensional scale analysis clustering is relatively close or they will be classified into the same cluster.

[0050] Through the relevant steps of the above-mentioned multi-dimensional scale analysis method, the clustering diagram of the Heat players in the two-dimensional space can finally be obtained, as shown in Figure 5 shown. As can be seen in the picture, the four starters James, Wade, Bosh and Chalmers often assist and cooperate with each other, while the four substitute players Cole, Lewis, Beasley and Anderson gather together. F...

Abstract

The invention discloses a competitive sports teamwork mode analogy method based on chordal graph visualization. The method comprises the following steps: 1) establishing a foundation database of game related information; 2) constructing a chordal graph according to the assisting information of players in a single game live broadcast record, i.e. dividing each player into a scoring sector and an assisting sector, respectively representing a scoring record and an assisting frequency record of each player, connecting the corresponding assisting sectors and scoring sectors of both cooperated parties by a chord so as to obtain a detail record of a game; 3) clustering the players with a multidimensional scaling method according to the historical record data of mutual assisting information of players in a team to obtain the two-dimensional coordinates of m vectors so as to obtain the clustering information of m players. Compared with the prior art, the competitive sports teamwork mode analogy method has the characteristics that chordal graph visualization design is adopted so as to bring convenience for users to better know and analyze game score distribution and player cooperation situations.

Description

technical field [0001] The invention relates to the technical field of visual analysis of information. It uses chord diagrams to visually display and interactively analyze the score coordination information between players in the game. At the same time, it analyzes the coordination tendency between team players through a multi-dimensional scale analysis method, and then effectively studies the ball. The team's tactical structure. Background technique [0002] In competitive team sports competitions, due to tactical arrangements and coordination tendencies, some players often cooperate with each other to score points. These cooperation modes are very important for both offense and defense. Through the study of one's own cooperation mode, targeted tactical adjustments can be made, and Studying the opponent's related patterns can effectively gain insight into the tactical structure, and then arrange appropriate defensive strategies. Therefore, researching team coordination stra...
