High-speed railway side slope deformation detection method and device

Abstract

The invention discloses a high-speed railway side slope deformation detection method and device. The method comprises the steps of obtaining the three-dimensional point cloud data of a side slope along a high-speed railway through a high-speed railway side slope point cloud collection system which comprises laser radar equipment, a mileage positioning synchronization unit and a point cloud data acquisition server, performing point cloud registration processing on the three-dimensional point cloud data by using an iterative closest point algorithm according to the reference point cloud data in the high-speed railway scene, extracting current side slope point cloud data from the three-dimensional point cloud data after point cloud registration processing, and extracting reference side slope point cloud data from the reference point cloud data in the high-speed railway scene, respectively carrying out voxelization processing on the current side slope point cloud data and the reference side slope point cloud data, and carrying out high-speed railway side slope deformation detection according to a voxelization processing result. According to the embodiment of the invention, the high-speed railway side slope deformation can be detected, the detection cost is saved, and the detection efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of high-speed railway safety, in particular to a method and a device for detecting deformation of a high-speed railway slope. Background technique [0002] In recent years, my country's railway high-speed process has been accelerating, how to ensure the safety of high-speed railway operation has become the key work of the railway safety management department. There are many large buildings such as tunnels and slopes in mountainous areas of high-speed railways. Due to the influence of geological activities and weather changes, especially in the line sections with more precipitation in southern my country, the risk of landslides on slopes is high and poses a serious threat High-speed railway operation safety. Therefore, it is necessary to regularly detect the shape change of the slope along the high-speed railway, statistically analyze the deformation trend of the slope, and find out the potential landslide ri...

Problems solved by technology

[0004] However, the high-speed railway has a long mileage, a large span, a large number of slopes, and scattered locations. The existing dynamic detection methods cannot repeatedly observe multiple scattered targets in a short period of time. The cost of data collection is high, and the data processing steps are complicated. Realize the purpose of efficient detection of high-speed railway slope deformation

In addition, high-speed railway slopes generally exist in mountainous areas, and the terrain is complex. It is impossible to erect and maintain fixed monitoring equipment, and the existing static monitoring methods cannot be used.
