Slope displacement monitoring method and system based on universal laser LIDAR

Abstract

The invention relates to a slope displacement monitoring method and system based on universal laser LIDAR, and belongs to the field of laser detection technology, the slope displacement monitoring method comprises the following steps: data acquisition: after an acquisition signal is triggered, periodically transmitting pulse laser to a measured slope, acquiring multiple groups of distance data about the measured slope, and recording the acquisition time; digital elevation model generation: based on a digital simulation method, obtaining a digital elevation model corresponding to each group of distance data; generation of a hotspot map: comparing and processing the digital elevation models obtained in the reporting period by units, generating a hotspot map about unit displacement, and obtaining displacement information, wherein the displacement information comprises a first displacement value; and data updating: sending the hotspot map and the displacement information to a remote monitoring center. Compared with the prior art, the application has the effect of facilitating landslide monitoring.

Description

technical field [0001] The present application relates to the field of laser detection technology, in particular to a slope displacement monitoring method and system based on universal laser LIDAR. Background technique [0002] my country has a vast territory and various topography, plains and mountains are the most common terrains in our country. The area of ​​mountainous areas in my country is larger than that of plains, accounting for about 69.1% of the country's land area. The mountain area is large and has advantages in the development of forestry, tourism, animal husbandry and mining. However, the mountainous terrain is rugged, and the resources of arable land and housing are limited. [0003] It is difficult for people living in mountainous areas to find flat land to build houses, so most of them solve the housing problem by cutting slopes and building houses. However, after the slope is cut, the stress of the mountain is released and the structure of the mountain c...

Problems solved by technology

Current landslide monitoring methods include manual monitoring methods and monitoring device monitoring methods. Manual monitoring is difficult to detect tiny landslides. The method of monitoring device monitoring generally observes the movement of monitoring components on the monitoring device for monitoring, but the operation of monitoring components needs to be monitored. On-site reading by personnel, otherwise it is difficult to know the landslide situation in time, so it is not convenient for landslide monitoring
