Abstract

The invention provides a video retrieval method and device and electronic equipment, and the method comprises the steps: obtaining a target frame which is obtained by detecting predetermined objects through a camera; performing feature extraction on the predetermined objects in the target frame to obtain a predetermined feature vector; according to the predetermined feature vector, retrieving whether a target object exists in the target frame or not to obtain a retrieval result, wherein the target object is one of the predetermined objects. In the scheme, the predetermined objects are detected through the camera to obtain the target frame, and then only whether the target object exists in the target frame or not needs to be retrieved, and all frames in the video do not need to be retrieved, so that the retrieval times can be reduced, high retrieval efficiency is ensured, and the problem of low efficiency of video retrieval in the prior art is solved.

Description

technical field [0001] The present application relates to the field of video retrieval, in particular, to a video retrieval method, retrieval device and electronic equipment. Background technique [0002] At present, video surveillance technology is developing rapidly, and the monitoring process will generate a large amount of data. Users often need to find specific objects from a large number of surveillance videos. Manual search is time-consuming, laborious, inefficient, and easy to miss when people are tired. Therefore, automated methods for retrieving specific objects in surveillance video are valuable. [0003] The inventors have learned that the existing video retrieval methods usually detect salient objects such as people or cars in the video frame, and then use the feature extractor to abstract the segmented object graph into high-dimensional vector features, and the high-dimensional vector features to be queried The two-dimensional vector features are matched with...
