Slope safety monitoring and early warning device and early warning method

Abstract

The embodiment of the present invention discloses a slope safety monitoring and early warning device and an early warning method. The device includes: a cloud platform; a laser radar arranged on the cloud platform for real-time acquisition of point cloud data of the target slope; The camera on the cloud platform is used to acquire the image data of the target slope in real time, and the laser radar and the camera have been pre-calibrated; the controller is used to filter the point cloud data and remove outliers points, the controller is also used to fuse the point cloud data and the image data after removing outliers through conversion matrix operations to obtain color image data with three-dimensional coordinates; the controller is also used to obtain color image data according to the color The image data monitors the depth change of the slope surface, and when a disaster or deformation of the target slope is detected, an early warning is sent to the cloud. Compared with the traditional slope monitoring means, the invention has high slope modeling precision, convenient device layout and low cost.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of slope safety, in particular to a slope safety monitoring and early warning device and an early warning method. Background technique [0002] With the rapid development of highway construction, geological disasters on highway slopes also occur from time to time, mainly concentrated in areas with complex geological environments such as the Southwest, where natural disasters such as collapses, landslides, debris flows, and ground fissures are prone to occur. In other areas, slope safety hazards are mostly distributed along the sides of highways, railways, and banks of dam areas. The large span of line engineering also increases the difficulty of slope monitoring. The losses caused by slope disasters are huge, and the geological disasters caused by slope instability cause damage to road facilities and heavy losses; slope instability seriously affects the normal operation of roads and...
