Embodiment 1

[0056] Taking the Xishan Village landslide as an example, the monitoring and early warning of the Xishan Village landslide was carried out according to the geological survey data. A method for early warning of mountain disasters, comprising the following steps:

[0057] (1) UAV fixed-point aerial photography of 720° panorama, on-site image collection in September 2017 and December 2017 respectively. Create corresponding folders, such as figure 1 , where (a) is the selection of aerial images in September, and (b) is the selection of aerial images in October.

[0058] (2) According to the principle of camera imaging, multiple continuous photos collected by the UAV in September and December are continuously projected on the projection surface to produce a spherical static panorama, and the sky is filled and image processing is performed at the same time. Such as figure 2 As shown, where the picture length: width = 2:1.

[0059] (3) Landslide video texture extraction and dyna...

Abstract

The invention provides a mountain disaster early-warning method and system. The mountain disaster early-warning method comprises the following steps that mountain disaster data are collected under thesame view point; static panoramas are spliced and synthesized; video textures in the mountain disaster motion process are generated; the static panoramas and the video textures are combined to generate a constructed dynamic panorama; and multi-period images are overlaid, and the change of the elevation and horizontal displacement before and after mountain disaster deformation is quantitatively analyzed. According to the mountain disaster early-warning method, the video textures and the panoramas are combined, the dynamic panorama in the deformation process of mountain disasters such as the landslide and the debris flow is constructed, meanwhile, the multi-period images are overlaid, the quantitative analysis result of mountain disaster deformation data is obtained, and the mountain disaster is early warned.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring and early warning, in particular to a mountain disaster early warning method and early warning system. Background technique [0002] At present, landslides and mudslides are the main disasters in mountainous areas. In most cases, landslides and mudslides occur under the influence of heavy rain, and slide and flow rapidly under the action of gravity. [0003] Mountain disasters are often sudden and catastrophic, and they occur rapidly in a relatively short period of time and are very destructive. The occurrence process of mountain disasters is short. Taking landslides as an example, the entire sliding process usually takes about 1 minute. Once a landslide disaster occurs, it is extremely difficult to escape within such a short period of time. Therefore, early warning of mountain disasters is particularly important. Contents of the invention [0004] The invention provides a method ...
