AI Technical Summary

Technical Problem

In video surveillance systems, audio data collected by multiple cameras near or in the same space are similar, but the prior art stores the audio data collected by each camera separately, resulting in wasted storage resources.

Method used

By acquiring the audio data collected by each camera device in the same area, determining the similarity, selecting the reference audio data and the target audio data, and only the target audio data is stored in association with the identification of the reference camera device, avoiding repeated storage of similar data.

Benefits of technology

Effectively save storage resources, reduce the space occupied by repeated audio data, and achieve efficient storage of audio data in the same area.

Abstract

The present disclosure relates to the technical field of photography, and provides an audio data storage method and apparatus for a multi-camera device, and an electronic device. The method comprises: obtaining first audio data acquired by camera devices located in the same region; determining a first similarity between every two pieces of first audio data; determining at least two pieces of reference audio data on the basis of the first similarities, and determining a camera device corresponding to each piece of reference audio data as a reference camera device; determining a first audio quality of each piece of reference audio data; and determining target audio data on the basis of each first audio quality, and correspondingly storing storage paths of the target audio data and identifiers of the reference camera devices.
