Landslide displacement detection method and device based on live-action simulation

Abstract

The invention relates to a landslide displacement detection method and device based on live-action simulation, and the method comprises the steps: receiving landslide body information of a landslide detection region, wherein the landslide body information comprises the temperature value, humidity value, positioning data, inclination angle and multi-segment displacement data of each monitoring point; based on a kinetic model fitting algorithm, calculating and analyzing the temperature value, the humidity value, the positioning data, the inclination angle and the multi-section displacement dataof each monitoring point, and establishing a soil layer state curve of each monitoring point; establishing a two-dimensional displacement scene observation model according to each soil layer state curve; determining a sliding trend of the landslide mass according to the two-dimensional displacement scene observation model; based on the elevation data model, utilizing a three-dimensional curved surface matching algorithm to extract elevation data of each monitoring point; according to the two-dimensional displacement scene observation model, the sliding trend of the landslide body and the elevation data, three-dimensional analog simulation display is carried out on the landslide body in the detection area, so the accuracy of landslide prediction and early warning decision analysis is effectively improved.

Description

technical field [0001] The invention relates to the technical field of landslide detection, in particular to a landslide displacement detection method and device based on real-scene simulation. Background technique [0002] Landslides are one of the most serious types of geological disasters, posing a serious threat to the lives and properties of people living in mountainous areas, destroying roads and causing traffic paralysis, destroying oil and gas pipelines along the line, causing major economic losses and environmental damage, landslides in reservoir areas It will cause changes in the water level and seriously affect the safety of the dam. The hazard of landslide is huge, therefore, landslide monitoring has important social and economic significance. At present, the monitoring of landslides mainly includes methods based on video analysis, distributed optical fiber detection, GPS detection or synthetic aperture radar interferometry. These methods collect information and...
