Intelligent video monitoring system based on three-dimensional virtual scene

Abstract

The invention relates to an intelligent video monitoring system based on a three-dimensional virtual scene, comprising a video collection subsystem, an intelligent video analysis subsystem, a comprehensive display subsystem, a calibration and positioning subsystem, a comprehensive management subsystem, a retrieval playback subsystem, and the like, wherein the video collection subsystem collects amonitoring video; the intelligent video analysis subsystem detects, identifies and tracks a movement target in the video and then classifies the movement target; the comprehensive display subsystem displays a bidimensional video and the three-dimensional virtual scene of the target, and displays the movement target category and a path thereof in the superposing manner in real time in the three-dimensional virtual scene; the calibration and positioning subsystem realizes the positioning of the bidimensional target in the three-dimensional virtual scene on the basis of acquiring parameters inside and outside a camera; the comprehensive management subsystem is responsible for managing and scheduling tasks, such as the system configuration, the log generation and retrieval, the authority hierarchical management, the defense area configuration and defense arrangement / defense withdrawing, the target video storage, the system alarming output, and the like; and the retrieval playback subsystem retrieves, edits and playbacks the target video with an event as a main line.

Description

technical field [0001] The invention relates to an intelligent video monitoring system, in particular to an intelligent video monitoring system based on a three-dimensional virtual scene, which completes real-time monitoring of a monitoring area and is suitable for the field of security monitoring of key targets or areas. Background technique [0002] With the development of economy and science and technology, people put forward higher requirements for the safety of living and office environments; the safe operation and safety of key facilities or areas (nuclear power plants, hydropower plants, banks, highways and airports, etc.) that are related to the lifeline of the economy Protection, places of interest, and cultural relics museums (text museums and the Palace Museum, etc.) and security of key military targets and areas (such as armory) put forward higher requirements; The remote analysis of events, the rapidity and accuracy of command and dispatch put forward higher req...

Problems solved by technology

However, traditional video surveillance uses a multi-camera window combination monitoring, which relies on the reliability of perimeter detection and the sense of responsibility of the on-duty personnel. If the perimeter detection fails or the intruder breaks through the perimeter without reporting to the police, or when there are more than 16 cameras, manual work cannot be done. Depending on the detected target and target orientation, it can only be viewed by frequently manually switching the tracking camera, and the position and orientation of the target can be guessed, especially when multiple moving targets cross-border alarm events occur, the system cannot complete the target-based tracking Multiple camera channels record independently and continuously. During video retrieval and playback, it is necessary to manually search for the camera channels and the remaining clips that the moving target passes through one by one. Therefore, the traditional video surveillance system has low monitoring efficiency, heavy tasks for security personnel, and incidents. When it happens, it is not conducive to on-site command and real-time scheduling, video retrieval and playback efficiency
