AI Technical Summary

Technical Problem

In existing technologies, network fluctuations between video encoding devices and video management platforms can cause alarm termination messages to be missed, resulting in continuous video storage, wasting storage space and affecting subsequent analysis. Furthermore, existing methods based on fixed time intervals offer poor flexibility.

Method used

Upon receiving an alarm notification, the alarm detection method is determined based on the alarm termination criteria. The feature values ​​of the alarm frame image and the current frame image are calculated and compared to determine whether the alarm has ended, thereby accurately storing the valid video stream.

Benefits of technology

It enables automatic judgment when alarm termination messages are lost, saving storage space and improving the accuracy of video storage and analysis results.

Abstract

This invention discloses a method, apparatus, electronic device, and storage medium for determining the end of an alarm. The method includes: if it is determined that an alarm prompt sent at the alarm time is received and the alarm end judgment condition is met, then, based on the alarm prompt, determining an alarm detection method; determining the alarm feature value of the alarm frame image corresponding to the alarm time; and, based on the alarm detection method, determining the current feature value of the current frame image; and, based on the alarm feature value and the current feature value, determining whether the alarm has ended. This invention can effectively determine whether an alarm has ended, thereby accurately storing valid video streams and saving storage space.
