Remote real-time monitoring method of dump site displacement based on monitoring images

Abstract

The invention discloses a remote real-time monitoring method for dump site displacement based on monitoring images, belonging to the field of dump site displacement monitoring. The device adopted in the method includes a digital camera, a wireless image data transmission module, a remote terminal computer, a voice alarm device, a solar panel and a storage battery. The digital camera is connected with the contact thread of the image data wireless transmission module through the USB cable, the image data wireless transmission module is connected with the remote terminal computer through the 3G / 4G network and the wired broadband Internet network, and the solar panel is connected with the digital camera and the image data wireless transmission module , the storage battery is connected, and the storage battery is connected with the digital camera and the image data wireless transmission module. The device can work continuously for a long time. The monitoring method can accurately determine whether there is displacement in the monitoring area. If there is displacement, it will alarm in various ways, effectively avoiding "false" landslides and false alarms, and accurately delineate the displacement area with stable accuracy.

Description

technical field [0001] The invention belongs to the field of displacement monitoring of dump sites, in particular to a remote real-time monitoring method for displacement of dump sites based on monitoring images. Background technique [0002] The stability of the slope of the dump site is related to the safe production of the mine and the technical and economic benefits. Therefore, monitoring the deformation of the slope of the dump site can detect sliding and creeping in time, which is very important for the effective prevention and control of landslides. significance. For the deformation monitoring of the slope of the dump site, the traditional monitoring methods include: engineering survey, GPS fixed-point monitoring, InSAR technology, three-dimensional laser scanning technology, etc. Among these methods, only GPS fixed-point monitoring can realize real-time, dynamic, and online monitoring, and other monitoring methods are not real-time; engineering survey and GPS fixed-...

Problems solved by technology

However, the device has the following problems: 1) The image acquisition and data processing devices are temporarily placed in the open air, and the staff cannot stay away from the equipment, so they cannot work continuously for a long time; 2) The displacement text of the landslide is transmitted to the command center through the wireless network 3) The algorithm "based on image local combination feature vector set" is used for image matching, and this matching algorithm also has matching errors, which will cause "false" landslides and false alarms; The density and distribution are limited by the texture characteristics of the target image. Therefore, the accuracy of sliding area delineation based on such points with the same name is unstable and cannot meet the requirements of accurately delineating the sliding area.
