Embodiment

[0094] Now take the application of the present invention to an earthquake-seismic area in a certain county of Aba Tibetan and Qiang Autonomous Prefecture in a certain province as an example. The present invention will be described in detail with reference to the accompanying drawings. However, they do not constitute a limitation of the present invention and are merely examples. At the same time, the advantages of the present invention are made clearer and easier to understand through the description. This embodiment also has guiding significance for the application of the present invention to rapid remote sensing monitoring in mountain torrent disaster-prone areas in other regions, and realizing remote sensing image recognition and monitoring evaluation of landslide bodies, debris flow deposits and debris flow gully beds.

[0095] The method for identifying hyperspectral remote sensing images of mountain torrent disasters in this embodiment includes the following steps:

Abstract

The invention discloses a mountain torrent disaster hyperspectral remote sensing image identification method. The method comprises the following steps: step 1, constructing an unmanned aerial vehicleremote sensing system; step 2, compiling a pre-flight preparation work manual and an unmanned aerial vehicle operation manual of an unmanned aerial vehicle; step 3, testing the working state of an unmanned aerial vehicle-mounted micro hyperspectral imager; step 4, determining image recognition performance and parameters; step 5, collecting data on site by the unmanned aerial vehicle remote sensingimage system; step 6,performing ground object spectral characteristic judgment and mountain torrent characteristic factor evolution analysis and recognition by an image recognition system; step 7, performing calculation and judgment by a recognition method subsystem; and step 8, recognizing mountain torrent characteristic factors, and outputting a mountain torrent ditch mountain torrent characteristic factor spatial distribution diagram of a monitoring area. The method has the advantages of realizing the accuracy, reliability and timeliness of the basic data information of landslide and debris flow areas in the mountain torrent disaster-prone areas. The invention further discloses a mountain torrent disaster hyperspectral remote sensing image identification system.

Description

Technical field [0001] The invention relates to the technical field of mountain torrent disaster monitoring and early warning, and more specifically it is a method for identifying mountain torrent disaster hyperspectral remote sensing images. The invention also relates to an identification system adopted by the method for identifying the hyperspectral remote sensing image of the mountain torrent disaster. Background technique [0002] Against the background of global warming and frequent extreme weather, my country is facing increasing risks of natural disasters in recent years, and is entering a period of frequent natural disasters. Among the many disasters, mountain torrents and their secondary disasters are the most severe flood disasters faced every year, especially in the hilly areas, many towns or residential areas are located at the mouths of mud-rock flows, river valleys and even landslides. Mountainous areas in my country account for about two-thirds of the country's la...
