Embodiment Construction

[0011] The use of fire insurance 3S&3D real-scene intelligent zoning method is an improvement and innovation of traditional fire prevention and provides a new fire monitoring method, specifically:

[0012] (1) The fire risk factor is used as the independent variable, and the occurrence of forest fire is used as the dependent variable to participate in the establishment of the model. Select location (longitude, latitude), weather (average surface temperature, sunshine speed, daily precipitation, daily average relative humidity, daily average air pressure, daily average temperature, daily average wind speed), terrain (altitude, slope, aspect), society Humanities (distance from roads, high-voltage lines, power stations, cemeteries, temples, weapons and ammunition depots, chemical plants, distance from residential areas, population density, stations, docks), vegetation (NDVI, vegetation types, combustibles) a total of 26 variables as the initial reference factor for building the m...

Abstract

The invention discloses a fire danger 3S&3D real-scene multi-element intelligent zoning method. The 3S&3D real-scene multi-element intelligent zoning method is applied to fire danger prevention. High-resolution remote sensing images and DTM data obtained by aerial survey of an unmanned aerial vehicle are used as main data sources, an LBS technology and a 3S technology are combined to establish a subcompartment division system, subcompartment boundary lines are nested on a 3D real-scene picture, and a database is established by applying multi-period second-class survey data; and a forest fire risk zoning and grading model is established by using an analytic hierarchy process, and a forest fire grade analysis platform is established, so that real-time dynamic zoning and prediction are realized, forest fire is prevented, and corresponding effective forest fire early warning management is realized.

Description

1. Technical field [0001] The invention relates to a fire risk intelligent zoning method, in particular to a fire 3S&3D real-scene intelligent zoning method. 2. Background technology [0002] Forest fire prevention plays a key role in preventing unnecessary loss of life and property caused by fire hazards, and in order to ensure the long-term and stable development of forestry. In view of the complexity of the internal situation of the forest, it is inefficient and costly to use traditional artificial methods for supervision. Using the traditional supervision method is time-consuming and labor-intensive, and requires a lot of manpower and financial resources on forest fire prevention. However, the traditional fire risk supervision method also has great limitations and disadvantages, and it is difficult to carry out real-time and dynamic monitoring. In order to better carry out forest fire prevention and protect the safety of people's lives and property. Therefore, be badl...
