A kind of avalanche information extraction method, device, electronic device and storage medium

Abstract

The embodiment of the present invention provides an avalanche information extraction method, device, electronic equipment, and storage medium. The method includes: first obtaining satellite remote sensing image data and UAV lidar point cloud data of the area to be measured, and then using the pre-built area The best avalanche simulation model to obtain the potential avalanche simulation value of the area to be tested. Then, according to the potential avalanche simulation value, the probability of avalanche formation area in the area to be measured is divided, and the information of the level of avalanche disaster in the area to be measured is obtained. The device is used to perform the above method. The embodiment of the present invention obtains the information of the area to be tested by using satellites and unmanned aerial vehicles, and then uses the pre-established optimal avalanche simulation model of the area to obtain the potential avalanche simulation value corresponding to the area to be tested, and extracts the avalanche disaster in the area to be tested Level information, such as: potential avalanche area and avalanche movement path. Since the information obtained by satellite remote sensing and drones will be more comprehensive, the accuracy of avalanche information will also be improved, and avalanche prevention and control can be carried out more comprehensively.

Description

technical field [0001] The present invention relates to the field of information extraction, in particular to an avalanche information extraction method, device, electronic equipment and storage medium. Background technique [0002] Avalanches are a natural environment in cold and snowy areas. When the snow on a mountain slope reaches a stable value, a large number of snow bodies slide down under the joint action of terrain slope, underlying surface type, snowfall and snow layer structure. of natural phenomena. [0003] Avalanches are characterized by suddenness, fast movement, and great destructive power. The process can be divided into three stages: formation, movement, and accumulation. It can destroy large forests, damage houses, traffic lines, communication facilities and vehicles, and block rivers. At the same time, it can also cause natural phenomena such as landslides, landslides and mudslides. Therefore, avalanches are classified as a serious natural disaster in s...

AI Technical Summary

Problems solved by technology

Because avalanche disasters mainly occur in high mountain areas with inaccessible people and heavy snow cover, the terrain and landform are very complex, and it is not only difficult to carry out on-site investigation work, but also risking a great deal of life, which makes it difficult to fully investigate the situation of avalanche disasters
