Title:
DISASTER CLASSIFICATION METHOD FOR LANDSLIDES AND COLLAPSE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/193823
Kind Code:
A1
Abstract:
The present invention belongs to the field of geological disaster classification. Disclosed are a disaster classification method for landslides and collapse, and an electronic device. The method comprises: step one, acquiring the topographical distribution of a surface mountain and the hillside elevation data of same, calculating a hillside slope and performing statistical analysis; step two, defining, regarding landslides and collapse, a critical value k, (I), where s is a slope, max(s) is the maximum slope value, s10％ is a 10th percentile of the slope, and avg(s) is an average slope value; and step three, when k is greater than a threshold value, determining a mountain disaster to be a landslide, otherwise, determining same to be collapse. By means of the present invention, accurate collapse and landslide classification can be realized by means of acquiring a digital elevation model (DEM) for geological disasters, without the need of performing manual field survey, thereby saving on a large amount of manpower and time, and improving safety guarantees.
