Problems solved by technology
[0002] At present, the total amount of highway construction in my country has achieved leapfrog growth, and the overall transportation tension has been eased. There are a large number of high-risk slopes on the completed highways. Slope collapse is one of the main highway geological disasters, and it is widely distributed and occurs frequently. It is very easy to cause traffic interruption, which directly affects traffic safety.
[0003] At present, the problem existing in the monitoring of high-risk slopes of highways is: to bury sensors on the slopes to monitor the displacement of the slopes. certain professional knowledge

experiment example
[0064] In order to verify the feasibility of the application of this patent in road slope monitoring, paper checkerboard is used as the deformation test material, and the size of each grid is 30*30mm. The edge of the checkerboard is manually squeezed to monitor the deformation of the paper checkerboard. Deformation situation. The simulation process is shown in Figure 3(a) to Figure 3(j), where Figure 3(a), (b), (c), (d), and (e) are the deformation process of the inner paper checkerboard, respectively, and Figure 3 3(f), (g), (h), (i), and (j) are the corresponding monitoring results respectively, the black point set is the 3D point set of the monitoring points laid out, and the other dark gray areas are the reconstructed triangular mesh surface. After error analysis, the average error of this experiment is about 2mm.

The invention discloses a road high-dangerous slope monitoring method based on a double-camera imaging technology, which belongs to the technical field of the slope monitoring method, and the method comprises the following steps of three-dimensionally rebuilding a slope: installing cameras along the length direction of the slope to be monitored, and ensuring that each scheduled monitoring point simultaneously stays within a photography range of two cameras; (2) monitoring the slope: calculating a space coordinate of the monitoring points which are distributed on the slope according to images photographed by the two cameras to obtain a space coordinate set of the monitoring points, periodically calculating a Euclidean distance of three-dimensional spaces of every two adjacent monitoring points, and monitoring the variation situation of the slope; and (3) predicting slope disaster: comparing a monitored slope displacement or slide value with a preset allowed critical value, and processing according to a preset rule. The road high-dangerous slope monitoring method is simple in structure, high in measurement and control precision and low in cost and used for monitoring the high-dangerous slope.
Description
technical field [0001] The present invention relates to a side slope monitoring method, and more specifically relates to a method for monitoring high-risk side slopes of highways based on dual-camera imaging technology. Background technique [0002] At present, the total amount of highway construction in my country has achieved leapfrog growth, and the overall transportation tension has been eased. There are a large number of high-risk slopes on the completed highways. Slope collapse is one of the main highway geological disasters, and it is widely distributed and occurs frequently. It is very easy to cause traffic interruption, which directly affects traffic safety. [0003] At present, the problem existing in the monitoring of high-risk slopes of highways is: to bury sensors on the slopes to monitor the displacement of the slopes. Certain expertise. Contents of the invention [0004] The purpose of the present invention is to provide a method for monitoring high-risk ro...
