Three-dimensional intelligent video monitoring method

Abstract

The invention relates to a three-dimensional intelligent video monitoring method, which comprises the following specific steps of: firstly, performing three-dimensional modeling on an actual monitoring area and displaying a three-dimensional virtual scene corresponding to the actual monitoring area by using software; secondly, calibrating a camera to acquire the internal and external parameters and distortion correction parameter of the camera and establishing a two-dimensional image and three-dimensional space one-to-one mapping relational model; thirdly, intelligently analyzing a monitoring video acquired by the camera to acquire moving target information comprising a target category, a moving path and the like; fourthly, positioning target information in a two-dimensional image in a three-dimensional space and displaying the target information in the three-dimensional virtual scene in real time; and finally, storing a target two-dimensional video and the moving path in the three-dimensional space synchronously for system retrieval and playback. In the method, a two-dimensional moving target is positioned in the three-dimensional virtual scene by fully utilizing the real three-dimensional space feeling of the three-dimensional virtual scene, so that the ability of monitoring personnel of quickly positioning and processing an alarm event is improved and the workload of the monitoring personnel is effectively relieved.

Description

technical field [0001] The invention relates to a three-dimensional intelligent video monitoring method, which can be used in the field of video monitoring and realizes rapid positioning of moving objects in a monitoring area in a three-dimensional virtual scene. Background technique [0002] With the development of economy and technology, people put forward higher requirements for the safety of living and office environment; the safe operation and safety of key facilities or areas (nuclear power plants, hydropower plants, banks, highways and airports, etc.) Higher requirements are put forward for protection, the security of historical sites and cultural relic museums (Writing Museum and the Palace Museum, etc.) and the security of key military targets and areas (such as armouries); when emergencies occur in key targets and areas, the on-site The rapidity and accuracy of remote analysis, command and dispatch of events put forward higher requirements. An important means of s...

AI Technical Summary

Problems solved by technology

However, with the rapid increase in the number of video detectors, traditional manual passive monitoring is far from meeting the needs of monitoring tasks, especially after an emergency occurs, it is very difficult to record all video playback, on-site command and dispatch of the event , and it is impossible to accurately locate the location of the non-video alarm device in time
