A roadbed settlement monitoring method and system based on image processing

Abstract

The invention discloses a roadbed settlement monitoring method and system based on image processing, wherein the realization of the method includes: collecting the signage image on the roadbed, extracting the identification target area of ​​the identification plate image; extracting the regional feature point coordinates from the identification target area ; The distance between two specific marked target points in the actual three-dimensional space is calculated by using the coordinates of the characteristic points in the marked target area, and the degree of subgrade settlement is monitored according to the distance change between the two specific marked target points. The present invention performs image processing on the signboard image on the roadbed, and realizes the monitoring of the roadbed settlement by calculating the distance between two specific marked target points, and can realize fully automatic measurement, which greatly saves labor costs and ensures the measurement accuracy and real-time performance.

Description

technical field [0001] The invention belongs to the field of image processing, and more particularly relates to a roadbed settlement monitoring method and system based on image processing. Background technique [0002] "To get rich, build roads first." Roads are the arteries of economic development, without convenient transportation, there will be no economic development. It can be said that the success of China's reform and opening up is inseparable from the vigorous construction of roads and railways. Therefore, traffic monitoring is particularly important. Due to the long-term impact of extreme weather, the subgrade is prone to settlement and deformation. When the settlement accumulates to a certain extent, it is easy to cause major safety accidents, especially for railways. This requires that the frequency of subgrade settlement monitoring should be high, the real-time performance of monitoring should be good, and the monitoring results should be accurate. [0003] A...
