The invention discloses a method for extracting a wonderful clip of a badminton event video. The method comprises the following steps: acquiring a badminton video; carrying out transfer learning by adopting a Keras framework to obtain a visual angle classification model; segmenting a shuttlecock video according to the visual angle classification model to obtain broadcast visual angle shuttlecock video clips; determining the gravity center of the athlete through a YOLOv3 target detection model; and according to the gravity center of the athlete, determining the average speed of the whole playerin the broadcast viewing angle badminton video clips, and taking several broadcast viewing angle badminton video clips with the maximum average speed of the whole player as wonderful badminton videoclips. The invention relates to a segment segmentation link taking visual angle classification as a core and a wonderful segment extraction link taking judgment of the overall speed of a player as a core, and finally realizes a wonderful segment extraction method of a badminton match video, so that a user can directly appreciate match wonderful segments in the badminton match video, and the time cost of the user is saved.
Description
technical field [0001] The present invention relates to the technical field of sports video processing, and more specifically to a method for extracting highlights from badminton event videos. Background technique [0002] Sports video has a huge audience and great commercial application prospects. With the popularity of mobile devices and the Internet, users' demand for sports videos has shifted from directly watching full videos to diversified needs for videos. For example, directly watching the highlights and emergencies of the game in the video corresponds to the extraction of highlights and abnormal event detection in video analysis technology. And in the field of sports video analysis, there are many sports that have been studied, such as basketball, football, volleyball and tennis, etc., but less research has been done in the field of badminton, and there are still a lot of vacancies waiting to be filled. [0003] Highlight extraction techniques are currently mainly...
