Embodiment approach

[0081] refer to image 3 , as an implementation of triggering the acquisition signal, the method for triggering the acquisition signal includes:

[0082] 1011. Acquire a second displacement value measured by the landslide displacement detection device 30 with respect to the measured slope.

[0083] The landslide displacement detection device 30 includes an inclination accelerometer, which is embedded in the slope to be measured.

[0084] It should be noted that the inclination accelerometer can also be replaced by a displacement sensor or other measuring device capable of measuring landslide displacement, and can also measure the second displacement sensor.

[0085] 1012. Based on the displacement threshold, when the second displacement value is greater than the displacement threshold, trigger the acquisition signal.

[0086] The displacement threshold is a preset threshold, which may be a value obtained from historical experience data.

[0087] It should be noted that afte...

Abstract

The invention relates to a landslide displacement monitoring method, system and device based on binocular stereoscopic vision, and belongs to the field of machine vision, and the monitoring method comprises the steps: image processing: after an acquisition command is triggered, periodically obtaining a first image and a second image of a detected slope, recording the shooting time, calibrating a binocular image acquisition device, and obtaining a calibration result of the binocular image acquisition device; acquisition of a three-dimensional image: acquiring a three-dimensional image of the detected slope body; hotspot map generation: generating a hotspot map about unit displacement, and obtaining a displacement track and a first displacement value; and data reporting: reporting the hotspot map, the displacement track and the first displacement value to a remote monitoring center. Compared with the prior art, the method has the effect of improving the problem of low monitoring efficiency.

Description

technical field [0001] The present application relates to the field of machine vision, in particular to a method, system and device for monitoring landslide displacement based on binocular stereo vision. Background technique [0002] Landslide monitoring, through the observation and analysis of various landslide precursor phenomena, records various tasks in the process of landslide formation activities. Landslide monitoring is to understand and master the evolution process of landslides, analyze the factors of landslide disasters, and provide corresponding data for landslide prevention and treatment. my country has a vast territory and a large area of ​​mountainous areas. The prevention and treatment of landslides are important measures to protect the lives and property rights of people in mountainous areas. [0003] At present, common landslide monitoring methods include remote sensing method, monitoring device monitoring method, seam measurement method and so on. The mon...
