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.
