Abstract
This application provides a video retrieval method, a device, and a medium. The video retrieval method includes extracting a keyframe of a video from an Interactive Electronic Technical Manual (IETM) common source database (CSDB) in an IETM platform, transferring the keyframe to a Contrastive Language-Image Pre-training (CLIP) encoder, and storing the keyframe in a keyframe database. A CLIP image encoder is used to encode the keyframe to determine a fused vector of all keyframe features, and the fused vector is stored in a vector database as a video feature. A CLIP text encoder is used to encode video retrieval text to determine a text feature, and the text feature is stored in a text database. A similarity between the text feature and the video feature is calculated to determine a text-video similarity matrix. Video retrieval is performed based on the text-video similarity matrix, and determining a video retrieval result.
