Problems solved by technology
[0004] The method of manual extraction requires manual second-by-second search and manual recording of time nodes, and the manual workload is too large; the video clips containing bees in the video are often only a few seconds long, and cannot be automatically segmented according to the manually recorded time stamps Video clips containing bees; and no matter whether you use auditory or visual search, you can only determine the approximate range of the video clips containing bees, but not accurate to the frame (40 milliseconds level), resulting in low extraction accuracy
Using the image recognition method of the software, because the bees move fast and the target of the bees in the whole image is very small, the calculation process of recognizing the bees from the video image sequence is complicated, the recognition process takes a long time, and it is very easy to make mistakes. knowledge or omission

The present invention provides a method and device for extracting video clips of bees visiting flowers. The first time stamp and the second time stamp in the video are determined according to the characteristics of the audio signal in the video. According to the video of the flower video clip, the video clip of the bee visiting the flower is extracted according to the first time stamp and the second time stamp; thereby utilizing the feature that the audio signal of the bee buzzing sound of the bee in the video has very significant features, the audio from the video Starting with the characteristics of the signal, determine the two time stamps of the start and end of the bee flower visit video clip in the video, and then the video extraction software automatically extracts the bee flower visit video clip according to the two time stamps, compared with the manual extraction method The labor cost is saved, and compared with the image recognition method using software, the calculation is simple, the recognition time is short, and the recognition accuracy and extraction accuracy of the video clips of bees visiting flowers are improved.
Description
technical field [0001] The invention relates to the technical field of video processing, and more particularly, to a method and device for extracting video clips of bees visiting flowers. Background technique [0002] In the study of bees visiting flowers, it is necessary to collect a large number of video data of bees visiting flowers. Multiple cameras simultaneously shoot videos containing bees visiting flowers at multiple locations. Since it is impossible to determine when the bees will visit the photographed flowers, so It can only be taken continuously and uninterrupted, and then the video clips containing bees can be extracted. [0003] The method for extracting the video clips that contain bees at present, a kind of is by the method of manual extraction, extracting personnel searches the video clips that contain bees in the video according to the image of observing video or listens to the sound of video, and manually intercepts these video clips; One is the image rec...
