The present application relates to a video retrieval method, a video retrieval mapping relationship generation method, a device and a storage medium. The video retrieval method provided by the present application includes: obtaining a retrieval instruction, which carries retrieval information for retrieving a target frame image; and obtaining the target frame image according to the retrieval information and a preset mapping relationship. The video retrieval mapping relationship generation method provided by this application includes: using a feature extraction model to perform feature extraction operations on each frame picture in the video stream to obtain the key feature sequence corresponding to each frame picture; Input it into the text sequence extraction model for processing to obtain the text description sequence corresponding to each frame picture; according to the text description sequence corresponding to each frame picture, construct a mapping relationship. By adopting the video retrieval method, video retrieval mapping relationship generation method, device and storage medium provided by the present application, the efficiency of video retrieval can be improved, and the human-computer interaction is more intelligent.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a video retrieval method, a method and a device for generating a video retrieval mapping relationship. Background technique [0002] With the continuous advancement of technology, video is becoming more and more popular now. Video is not only used in TV systems and movie systems, but also in monitoring systems. However, the video in TV or movie lasts at least a few hours, while the video in the monitoring system is as few as a few days, and as long as several months or even years. However, in the current information age, a large amount of video information has been generated. Finding the lens you need in the massive video is undoubtedly a needle in a haystack. [0003] Taking TV dramas as an example, at present, when a user needs to search for a specific scene he needs in a large number of TV series videos, he usually traverses the entire video by fast-forwarding the...
