Side slope micro-deformation monitoring method and side slope micro-deformation monitoring system based on similarity determination criterion

Abstract

The invention discloses a side slope micro-deformation monitoring method and a side slope micro-deformation monitoring system based on similarity determination criterion, wherein the monitoring method includes the following steps: (1) image collection and synchronous uploading: collecting and uploading side slope surface images in a monitored zone, wherein the monitored zone is divided into K to-be-analyzed zones; (2) imaging receiving and synchronous processing: performing synchronous treatment to the received side slope surface images, including: (201) performing side slope surface image treatment at the initial sampling time and calculating the similarity of the side slope surface image at this time; (202) performing side slope surface image treatment at the next sampling time, and calculating the similarity of the side slope surface image at this time; and (203) determining whether the micro-deformation exists or not. The monitoring system includes K digital projectors, K image photographing devices, an image collection device and an image processing device. The method and the system are reasonable in design, are convenient to achieve, are good in use effect, and can be used for performing simple, real-time and accurate monitoring the side slope micro-deformation.

Description

technical field [0001] The invention belongs to the technical field of micro-deformation monitoring, and in particular relates to a slope micro-deformation monitoring method and a monitoring system based on similarity judgment criteria. Background technique [0002] The monitoring and real-time alarm of the micro-deformation of the slope surface are very important, such as the monitoring of the micro-deformation of the surface of the open-pit coal mine and the real-time alarm are related to the life safety of miners. When actually monitoring the micro-deformation of the slope surface, it is mainly to monitor the fission of the rock mass caused by the settlement. At present, the instruments or methods used to detect the micro-deformation of the slope surface include: total station, convergence meter, optical fiber sensing technology, etc. The above-mentioned detection technologies have their own advantages, but they also have defects and deficiencies to varying degrees, such ...

AI Technical Summary

Problems solved by technology

[0005] In view of the defects and deficiencies in the existing slope micro-deformation monitoring methods, if the 3D reconstruction method and image processing method can be combined and applied to the slope micro-deformation monitoring, the existing slope micro-deformation monitoring methods and corresponding problems can be effectively solved. The existing monitoring equipment has problems such as difficult monitoring, labor and time-consuming, real-time monitoring cannot be realized, and monitoring effect is poor.

In addition, the existing monitoring methods for slope micro-deformation and corresponding monitoring equipment still have the defect of inaccurate monitoring results. false alarm

[0006] In summary, there is a lack of a slope micro-deformation monitoring method and monitoring system based on the similarity judgment criterion that is reasonable in design, convenient in implementation, and good in use, and can monitor slope micro-deformation in a simple, real-time, and accurate manner.
