Problems solved by technology
[0002] The traditional evacuation method can only determine the evacuation direction of people when a fire occurs based on the initial position of the fire source, and cannot adjust the evacuation direction in real time according to the density of people in the passage and the trend of fire spread. On the other hand, it ignores the dynamic changes of the fire spread trend, which brings unnecessary casualties to people, and easily leads to stampede accidents.

Embodiment Construction
[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.
[0028] Below in conjunction with accompanying drawing, the three-dimensional GIS real-time evacuation method in the present invention is described in further detail:
[0029] In one embodiment of the invention:
[0030] Such as figure 1 As shown, the method is mainly based on the CNN (Convolutional Neural Networks) monitoring image analysis model, fire evacuation time prediction model, and fire spread monitoring model. The CNN-based monitoring image analysis model mainly provides personnel for the fire evacuation time prediction model. The distribution density and fire evacuation time prediction model are mainly responsible for calculating the estimated consumption time of personnel choosing different evac...

The invention provides a three-dimensional GIS intelligent escape system and method considering evacuation time, and the method comprises the steps: recommending a safe, time-consuming and short optimal evacuation path for a user according to the factors, such as the distribution intensity of people on a channel, fire spread monitoring, and the position of people, and presenting the optimal evacuation path to the user through a mobile client; according to the three-dimensional GIS real-time evacuation method, the optimal evacuation path of the mobile client can be continuously refreshed, and the optimal evacuation escape path changing along with the fire behavior in the scene where the user is located is displayed in real time.
Description
technical field [0001] The invention relates to the field of emergency evacuation indication methods, in particular to a three-dimensional GIS intelligent escape system and method considering evacuation time. Background technique [0002] The traditional evacuation method can only determine the evacuation direction of people when a fire occurs based on the initial position of the fire source, and cannot adjust the evacuation direction in real time according to the density of people in the passage and the trend of fire spread. On the one hand, it ignores the dynamic changes of the fire spread trend, which brings unnecessary casualties to personnel, and easily leads to stampede accidents. Since the population density of the evacuation channel cannot be directly obtained by simple means, it needs to be obtained by computer analysis of video surveillance images. The prediction of the fire spread trend needs to be combined with factors such as the type of combustibles, fire load,...
