Embodiment Construction

[0038] The present invention will be further described below through specific embodiments and accompanying drawings.

[0039] The 3D three-dimensional fire recognition method and system of the present invention uses virtual reality and video fusion technology to construct a virtual three-dimensional scene according to the ratio of 1:1 in the real world, projects the video into the three-dimensional scene, and performs fire analysis on the video through a mathematical algorithm. When a fire is found, it will call the police, realize real-time command of personnel evacuation, evacuation and other emergency facilities, and realize visual remote emergency command. The overall flow of the method is as follows figure 1 As shown, it specifically includes the following steps:

[0040] 1. Construct virtual digital earth and 3D scene

[0041] This step uses virtual reality technology to construct a virtual digital globe with a ratio of 1:1 according to the real world, and load the 3D ...

Abstract

The invention relates to a 3D stereoscopic fire identification method and system. The method comprises the following steps: 1) constructing a virtual digital earth by using a virtual reality technology, and loading a three-dimensional scene in the virtual digital earth; 2) mapping the real-time image of the surveillance video into the three-dimensional space scene to realize the fusion of the surveillance video and the three-dimensional scene; 3) carrying out fire diagnosis analysis on the monitoring video in the three-dimensional scene, so as to find the fire and give an alarm. Specifically,step 3) adopts the semantic partition and semantic fusion method based on CNN features to diagnose and analyze the fire. The invention provides a video multi-point fusion system which can be seen more, understood more and viewed widely for users, and can carry out fire analysis and alarm on the content in the video, thereby realizing real-time command of emergency facilities such as evacuation andevacuation of personnel, and realizing 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...
