Image query and information synchronization method and device

Abstract

The embodiment of the invention provides an image query and information synchronization method and device, and the method comprises the steps: determining target index information corresponding to a to-be-queried analysis result according to a second corresponding relation when the to-be-queried analysis result exists in a second storage region; and obtaining a target identifier of a storage sub-region corresponding to the to-be-queried analysis result from the target index information, and obtaining an image pointed by the target index information from the first storage region when the validity information of the target identifier is judged to be valid according to the first corresponding relationship. Through the technical scheme provided by the embodiment of the invention, an image is queried from the first storage area under the condition that the target identifier is judged to be valid, so that the query efficiency of the image is improved, the query operation is prevented from being continuously executed under the condition that the target identifier is invalid, and CPU resources are saved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to image query and information synchronization methods and devices. Background technique [0002] The recording and broadcasting host can store the images taken by the monitoring equipment, as well as the analysis results obtained by intelligently analyzing the stored images. The analysis results stored in the recording and broadcasting host correspond to the stored images, that is, the analysis results in the recording and broadcasting host are associated with images, and one image can correspond to one or more analysis results. When the user needs to query the image and the corresponding analysis result, the recording and broadcasting host can provide the corresponding image and analysis result for the user according to the association between the stored image and the analysis result. Wherein, the storage mode of images in the recording and broadcasting host is sub-area stor...

Problems solved by technology

[0003] When the storage area storing a part of the image is formatted, the part of the stored image will be deleted, and because some images may correspond to multiple analysis results, if the deleted image is filtered out from the stored analysis results The analysis results of deleted images are relatively cumbersome, so the analysis results of deleted images are generally not processed accordingly

However, if no processing is performed on the stored analysis results, when searching for deleted images according to the analysis results, the recording and broadcasting host will still perform the query operation, however, only the recording and broadcasting host will perform the last step: according to the Only when the storage location of the virtual query image is used to obtain the image can it be determined that the desired query image has been deleted, resulting in the inability to query the desired image

In this way, not only the CPU resources are wasted, but also the query efficiency of the image is reduced
