Football match offside judgment method and device based on unmanned aerial vehicle, and electronic equipment

Abstract

The invention discloses a football match offside judgment method and device based on an unmanned aerial vehicle, and electronic equipment, and the method comprises the steps: obtaining a real-time video of a football match, the real-time video being obtained by a visual sensor of the unmanned aerial vehicle; applying an identification algorithm to the current frame image of the real-time video to obtain a football detection area and a player detection area; performing feature extraction on the player detection area through cosine similarity, nonlinear normalization transformation and HSV transformation, and inputting the extracted features into a classification model to obtain category information of a team to which players belong; according to the football detection area and football player detection, judging whether passing occurs by judging whether an overlapping area exists between the football player detection area and the football detection area and comparing the distance between the center points of the football detection areas of the front frame and the rear frame, and if passing occurs, obtaining category information of a team to which the football player of the passing party belongs; according to the player detection area of the passing party and the information of the team, performing straight line detection, obtaining the position of an offside line, and performing offside judgment.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a method and device for judging offside in football matches based on unmanned aerial vehicles, and electronic equipment. Background technique [0002] Offside is a common type of foul in football games. The original way of judging offside by sideline referees is often due to lack of experience or physical decline of referees, resulting in a position that is not conducive to offside judgments, and then errors due to occlusion or viewing angle deviation. Penalties significantly affect the fairness of the game and the viewing experience of the audience. [0003] At present, in some higher-level football matches, an offside penalty system for football matches with a fixed perspective has been introduced. However, the technology is to process the playback video to assist the human eye to judge, rather than the machine making an offside penalty autonomously....
