Research on Recognition of Uniform Number and Player Identification Using Volleyball Game Video

Abstract

In volleyball, it is important to grasp the movement of each player and analyze the formation. Therefore, the authors developed a system that tracks the movements of athletes using the game video. However, to acquire the tracking result for each specific player, it is necessary to recognize a unique uniform number for each player. In previous research, there is a technology to recognize printed characters and handwritten characters. However, it is difficult to recognize the uniform number when distortion occurs in the uniform number as the direction of the player's body changes during the game, or when the uniform number is not able to be visually recognized. In this research, we develop a system that distinguishes movements of specific players from uniform numbers and tracking results using a video of volleyball games.
