Assistance system of badminton service referee based on vision

Abstract

The invention provides an assistance system of badminton service referee based on vision which can help a badminton service referee to judge the height of the ball in the moment of service. The specific scheme includes an acquisition module, a camera module, a storage module, a processing module and a display module; the acquisition module is used for acquiring the current height information, thecurrent time information and the current speed information of the badminton and sending the information to the storage module; the camera module is used for shooting the whole badminton game and sending the camera information to the storage module; the storage module is used for storing the camera information and the current height information, the current time information and the current speed information which are correlated with each other; the processing module is used for calculating the initial height information according to the current height information, the current time information and the current speed information in the storage module and sending the initial height information to the display module; the display module is used for displaying the initial height information sent by the processing module, and the display module is also used for displaying the camera information in the storage module.

Description

technical field [0001] The invention belongs to the technical field of sports competitions, and in particular relates to a vision-based auxiliary system for badminton serving referees. Background technique [0002] Whether the badminton serve is fouled is a key technical issue in the badminton game, and there are special serve referees to supervise and judge. [0003] Common service violations are based on the standard that "when serving the ball, the entire ball should be lower than the server's waist at the moment of hitting the ball". However, because the "waist" is not clearly defined, the subjective judgment of the serving referee is required when determining whether the serve is illegal. It is precisely because of the inclusion of subjective judgments that the entire judgment process is very non-standard. The judgment results based on the standard of "serving the ball over the waist" often cause objections and complaints. [0004] Therefore, in order to improve the s...

AI Technical Summary

Problems solved by technology

[0005] The above regulations avoid subjective judgment and are conducive to the fair implementation of the standard, but there is still the problem that it is difficult for the naked eye to judge the height of the ball at the moment of impact; and the naked eye observation has the following disadvantages:

[0006] 1. When observing with the naked eye, there are problems of line-of-sight priority and blind spots;

[0007] 2. The accuracy of naked eye recognition is relatively low;

[0008] 3. When there are objections and representations, valid evidence cannot be provided
