Badminton penalty method and device

Abstract

The application, which relates to the technical field of Internet of Things control, provides a badminton penalty method and device, thereby solving a technical problem of judging whether a badmintonis out of bound or not. The method further comprises the steps that: a server obtains position data of a badminton through a three-dimensional laser radar; the server determines the height and two-dimensional plane coordinates of the badminton according to the position data of the badminton, wherein the two-dimensional plane coordinates are used for indicating the position of the badminton in a two-dimensional plane coordinate system, a first coordinate axis in the two-dimensional plane coordinate system is parallel to the bottom line of the badminton court, and a second coordinate axis is parallel to the side line of the badminton court; and when the height of the badminton is smaller than the threshold value, the server judges whether the badminton is out of bound or not according to thetwo-dimensional plane coordinates of the badminton. The badminton penalty method and device is suitable for a badminton match scene.

Description

technical field [0001] The present application relates to the technical field of Internet of Things control, in particular to a badminton penalty method and device. Background technique [0002] In a badminton match, it is usually judged whether the round ends and the scoring side is judged by whether the shuttlecock touches the ground and the touch point. Different levels of competition have different ways of judging when a shuttlecock touches the ground. [0003] Large-scale badminton games have begun to introduce instant playback systems. Multiple high-definition cameras and high-performance computers are used to reconstruct the trajectory of the badminton, so that athletes can challenge the judgment of the line judge or referee; in small and medium-sized badminton games, digital The line judge or referee observes whether the shuttlecock touches the ground and the position of the touch point. [0004] However, in large-scale badminton games, the instant playback system ...

AI Technical Summary

Problems solved by technology

[0004] However, in large-scale badminton games, the instant playback system equipment is complex, expensive, and difficult to promote; in small and medium-sized badminton games, the labor cost is expensive, and the sight of line judges or referees is easily blocked by players or affected by their energy status. The misjudgment of the ball's landing point makes the players feel a certain amount of resistance, which is not conducive to the normal progress of the game
