Embodiment Construction

[0042] In the method for obtaining instructive game fragments in the table tennis game of this embodiment, a table tennis game with four wins in seven games is clearly presented in chronological order.

[0043] Improved ladder line graphs and score bars: e.g. figure 1 As shown, the light-colored ladder line represents the score of player 1, and the dark-colored ladder line represents the score of player 2. The coordinate axis on the left is a scale from 0 to 12 points. From this, we can see the difference between the scores of the two players in each game. Changes. Such as figure 1 In the lower part, you can see dots of different sizes representing rounds. The color of the dots can be used to know the distribution of the player's winning and losing rounds on the time axis. The dots represent player two winning. The size of the dots can be used to know the distribution of long and short rounds on the time axis. Through the background frame of the dots, it can be judged whic...

Abstract

The invention discloses a method for obtaining game fragments with guiding significance in table tennis games. The method comprises the following steps of: (1) obtaining a score of each round in eachgame in a table tennis game video, and a ball hitting skill, a ball hitting position a ball hitting drop point and a ball hitting effect attribute of each shot in each round; (2) visualizing the dataobtained in the step (1) into an improved ladder diagram and scoring bar, wherein according to the improved ladder diagram, two improved ladder lines in different colors are used for representing changes of score information, in all the rounds, of two players, and according to the scoring bar, a column diagram is segmented through a round number, and the segment of each game is further divided into a start stage, a middle stage and an end stage; and (3) obtaining game fragments with guiding significance according to matched changes of the improved ladder diagram and the scoring bar. Through the method disclosed by the invention, table tennis game data is processed, so that exploration and analysis in different levels can be carried out on scores and skill information of sequential table tennis games easily, intuitionally, comprehensively and deeply.
