Embodiment Construction

[0040] The technical content of the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0041] Lidar scanning technology is a new type of aerial measurement technology that has developed rapidly in the past ten years. It has been widely used in many industries at home and abroad, but it is rare in landslide monitoring applications. Because the ground 3D laser scanning technology can obtain the 3D space coordinates of the object surface at high speed, high precision and high density, and does not need to touch the measured object, it is especially suitable for application in the field of geological disaster monitoring such as landslide.

[0042] The non-contact landslide monitoring system provided by the present invention adopts a three-level architecture, including a monitoring center processing platform 1, a monitoring processing host 2, a lidar scanner 3, and a video review device 4. Among them, such as figure 1 A...

Abstract

The invention discloses a non-contact landslide hazard monitoring system, which comprises a laser radar scanner, a video check device and a monitoring center processing platform, wherein the laser radar scanner, the video check device and the monitoring center processing platform are connected with a monitoring processing host. The laser radar scanner is used for obtaining distance data of distance from each point in a landslide monitoring region to the laser radar scanner; the monitoring processing host is used for receiving the distance data collected by the laser radar scanner, obtaining an over-limit detection result and sending the over-limit detection result to the monitoring center processing platform; and when the monitoring center processing platform judges that the over-limit detection result surpasses the data threshold, the monitoring processing host triggers the video check device to collect videos to carry out recheck. The non-contact landslide hazard monitoring system monitors the whole landslide monitoring region by utilizing the three-dimensional scanning technique, so that the landslide geological disaster can be monitored accurately; and through linkage with the video check device, the monitoring system realizes an early warning-alarm-check processing mechanism. The invention also discloses a corresponding monitoring method.

Description

Technical field [0001] The invention relates to a landslide disaster monitoring system, in particular to a non-contact landslide disaster monitoring system. The invention also relates to a monitoring method realized by using the above landslide disaster monitoring system, and belongs to the field of geological disaster monitoring. Background technique [0002] A landslide is an overall sliding failure phenomenon that occurs when part of the rock and soil forming the slope is sheared along a certain weak surface inside the slope under certain natural and geological conditions. In recent years, accidents caused by landslide disasters have occurred frequently, seriously threatening people's lives and property. [0003] There are mainly three types of existing landslide monitoring technologies: 1) traditional landslide monitoring technology; 2) distributed optical fiber monitoring technology; 3) GNSS displacement monitoring technology. The above three monitoring technologies are all c...
