Positioning ball video clip detection method, device and system and storage medium

Abstract

The invention discloses a method for detecting a place kick video clip. The method comprises the following steps of detecting position information of a football in each frame of picture of a footballgoal video clip by using a pre-constructed football detection model, wherein the football detection model is obtained by training a target detection algorithm based on a convolutional neural network by taking each picture in a football match picture training set as input and taking a football marked in the corresponding picture as a target; judging whether the positions of the footballs in any continuous N frames of pictures are changed or not according to the detected position information of the footballs; and in response to the judgment result that the position of the football in any continuous N frames of pictures is not changed, determining the football goal video clip as a place-kick video clip. By adopting the technical scheme provided by the invention, the intelligent degree and accuracy of positioning ball video clip detection can be improved; meanwhile, the invention further provides a positioning ball video clip detection device and system and a storage medium.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a positioning ball video segment detection method, device, system and storage medium. Background technique [0002] Football is one of the most popular sports, and major football game programs are also concerned by the majority of fans. Football game programs usually include video clips of various football events, such as video clips of football goals, wherein the video clips of set kicks are often attracting attention because they are more exciting. However, there is still no solution that can automatically distinguish whether the goal type of a football goal video clip is a set kick or an ordinary goal (that is, a goal type other than a set kick), that is, it cannot automatically detect whether a football goal video clip is a set kick. video clip. If you need to watch the set kick video clips, you need to manually screen the football goal video clips. Conten...
