3D three-dimensional fire recognition method and system

Abstract

The invention relates to a 3D three-dimensional fire recognition method and system. The method includes: 1) constructing a virtual digital globe using virtual reality technology, and loading a 3D scene into the virtual digital globe; 2) mapping the real-time image of the surveillance video to the 3D space scene to realize the fusion of the surveillance video and the 3D scene; 3) ) Diagnose and analyze the fire on the monitoring video in the 3D scene, so as to find the fire and call the police. Specifically, step 3) uses CNN feature-based semantic division and semantic fusion methods for fire diagnosis and analysis. The present invention provides users with a video multi-point fusion system that can be viewed more, understood, and widely viewed, and can perform fire analysis and alarm on the content in the video, so as to realize real-time command personnel evacuation, evacuation and other emergencies facilities to realize visual remote emergency command.

Description

technical field [0001] The invention belongs to the technical fields of computer graphics, virtual reality, digital image processing, etc., and specifically relates to a 3D three-dimensional fire recognition method and system, which can virtualize a real scene and access network video, and then perform algorithmic analysis on the accessed video, such as Analyze the fire and give an alarm prompt in time. Background technique [0002] Video surveillance plus some fire sensors (such as fire alarms, smoke alarms, etc.), as an important technical application in the security industry, has developed rapidly. With the continuous maturity and extensive application of virtual reality technology and fire analysis, these technologies are now also used in the security industry. The multi-point fusion of surveillance video and fire analysis system added with virtual reality technology, compared with traditional surveillance video, can enhance customers' spatial awareness, spatial geograp...

AI Technical Summary

Problems solved by technology

[0004] 1) Surveillance personnel usually need to face hundreds or even thousands of cameras, and the video matrix generally has less than 50 screens, which cannot effectively display video content

[0005] 2) It is difficult to remember the corresponding relationship of the video, it is inconvenient to switch and track, it is impossible to find the problem in time, and it cannot show the overall situation

[0006] 3) The traditional monitoring system can only monitor, but cannot perform fire analysis and alarm prompts
