Full-automatic anti-intrusion intelligent video monitoring alarm system for unattended villa

Abstract

The invention provides a full-automatic anti-intrusion intelligent video monitoring alarm system for an unattended villa, which relates to the technical field of intelligent monitoring systems. The anti-intrusion intelligent video monitoring alarm system comprises a video intelligent analysis system, an anomalous event analysis system and an anomalous event alarm system. The video intelligent analysis system particularly refers to automatically detecting an object through a subregion autonomous non-reference threshold algorithm and an object key information secondary extraction algorithm and automatically tracking the object by adopting a movement trend tracking algorithm merging Kalman filtering and particle filtering. By detecting and tracking the movement objective track information, the movement direction, the horizontal and vertical displacement, and the object center position of the object are determined. The anomalous event analysis system particularly refers to analyzing video signals acquired by a villa monitoring camera through a machine vision algorithm, judging anomalous and dubious behaviors of the objects (personnel) around and in a villa through a preset rule, and notifying information on pictures, characters and the like of the anomalous behaviors and events to a proprietor or a security department in time.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring systems, and relates to an intelligent video analysis system, and an abnormal event analysis and alarm system. The video intelligent analysis system specifically refers to the behavior of automatically detecting targets, automatically tracking targets, automatically identifying and analyzing targets. The abnormal event analysis system specifically refers to intelligently analyzing the video signals collected by the villa surveillance cameras through machine vision algorithms, and intelligently distinguishing and monitoring abnormal and suspicious behaviors of moving targets (personnel) around the villa and in the villa courtyard through pre-set rules, and alarming suspicious The target is kept away from the villa; and the pictures and text information of abnormal behavior events are promptly notified to the owner and the security department through MMS and SMS.

Problems solved by technology

There are many problems in this monitoring method. First of all, the number of scenes to be monitored is large, and it is very difficult to look at it completely through manpower. Secondly, traditional monitoring does not have the ability to actively respond to emergencies, and often can only be used as an after-event evidence collection video. Tool; Finally, it is inconvenient to save and retrieve video recordings, and often saves a large amount of useless video data
