Video processing method

Abstract

The invention provides a video processing method, comprising: for a security monitoring system including a video monitoring system and an audio monitoring system, when the audio monitoring system detects an abnormal sound change, recording the time of an abnormal event and writing in audio monitoring code stream, simultaneously analyzing the direction of sound, then adjusting a video monitoring camera to obtain an optional monitoring angle, opening video monitoring, recording the time of the abnormal event to synchronize with the audio monitoring code stream, and storing video codes; comparing different front and back images to determine an image block corresponding to the abnormal event, trying to perform analysis, and if the type of the abnormal event can be successfully analyzed to be a monitoring target event, handling the abnormal event according to a set handling mode; and if the monitoring target event cannot be detected, recording the abnormal event for later retrieval and query of monitoring personnel.

Description

technical field [0001] The invention relates to the field of security monitoring, in particular to a video processing method. Background technique [0002] With the development of society and the progress of science and technology, monitoring has already become an indispensable part of society. Surveillance is playing an increasingly important role in social security, traffic management, and smart cities. [0003] Today, video surveillance is still the absolute protagonist in the field of surveillance, such as traffic probes that can be seen everywhere on the road, closed-circuit surveillance systems in residential areas, and so on. [0004] In a video surveillance system, the video recorded by the camera needs to be stored for later retrieval and query. Due to the huge amount of data in the original video stream, it is necessary to perform video encoding on the original stream. [0005] Ordinary video coding standards are aimed at high-definition video coding and decoding...

AI Technical Summary

Problems solved by technology

However, the low-pixel monitoring quality sometimes has a certain adverse effect on the later search and query. For example, in many cases, the license plate number cannot be seen clearly in the monitoring video of the road monitoring probe.

[0006] At the same time, video surveillance also has its inherent shortcomings, such as the effect will be greatly reduced in the dark night or foggy weather, and there is a large blind area in the monitoring range

[0007] More and more phenomena show that pure video surveillance is increasingly unable to meet the continuously growing surveillance needs
