Embodiment 1

[0034] figure 1 It is a flow chart of a method for tracking security monitoring and early warning events in a preferred embodiment of the present invention; the method of the present invention is applied to monitoring equipment including audio, and includes the following steps:

[0035] S1: Set the current detected video frame and the initial value of the current audio valid data start detection frame number;

[0036] The initial value of the current valid audio data start detection frame number is Num+1, where Num represents the number of audio frames used for estimating the environmental signal-to-noise ratio or calculating the threshold when detecting the valid audio data.

[0037] In the embodiment of the present invention, the currently detected video frame is set as the first video frame image, and the current valid audio data start detection frame is set as the Num+1 audio frame.

[0038] S2: Carry out early warning point detection according to the early warning mode. ...

Embodiment 2

[0081] Figure 4 It is a structural diagram of a security monitoring and early warning event tracking system in a preferred embodiment of the present invention; the system includes:

[0082] The starting frame setting module is used to set the initial value of the current detection video frame and the current audio effective data start detection frame sequence number;

[0083] The initial value of the current valid audio data start detection frame number is Num+1, where Num represents the number of audio frames used for estimating the environmental signal-to-noise ratio or calculating the threshold when detecting the valid audio data.

[0084] The early warning point detection and processing device is used to detect the early warning point according to the early warning mode. When an early warning event is detected, enter the first relevant parameter update module of the early warning event, otherwise continue to detect the early warning point until the end.

Abstract

Theinvention provides a tracking method and system of a security monitoring and early warning event. The tracking method of the security monitoring and early warning event provides complete warning start and stop time points of each early warning event for a monitoring system, thus checking during the investigation period for users is convenient, andthe searching efficiency is improved; meanwhile,the tracking method of the security monitoring and early warning eventestablishes a hierarchical warning of the locally recorded video file, so that abnormal event information can be obtained in an most efficient mode by video viewers according to limitation of time.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a tracking method and system for security monitoring and early warning events. Background technique [0002] Security monitoring is a main direction of video applications in recent years. Whether it is for public application monitoring or home application monitoring, it is necessary to have an effective abnormal event early warning and tracking mechanism, which can greatly reduce the massive video data during abnormal event investigation. This is especially important for monitoring systems without real-time feedback. Existing monitoring systems generally do not have effective early warning and tracking mechanisms for abnormal events, resulting in the need to search massive amounts of video data when investigating abnormal events, which takes a long time and low efficiency. Contents of the invention [0003] The purpose of the embodiment of the present invention is ...
