Embodiment Construction

[0073] like figure 1 A slope micro-deformation monitoring method based on the similarity criterion is shown, including the following steps:

[0074] Step 1. Image collection and synchronous upload: use the image collection device 2 to collect the slope surface images in the monitoring area according to the preset sampling frequency f, and synchronously transmit the slope surface images collected at each sampling time to image processing device 1 .

[0075] The monitoring area is the area where micro-deformation monitoring needs to be carried out on the side slope slope, and the monitoring area is divided into K areas to be analyzed, and the K areas to be analyzed are all square and have the same size; wherein, K is positive Integer and K≥2; the slope surface image is composed of K area images, and the K area images are K images of the to-be-analyzed area respectively.

[0076] The sampling moment of the image acquisition device, denoted as t h , t h = t 1 +(h-1)×Δt; where...

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 ...
