Problems solved by technology

[0011] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides an anti-interference landslide monitoring method based on image processing. By setting reference targets, the present invention solves the problem that the image acquisition device is biased due to thermal expansion and contraction of the bracket or other reasons. The problem of affecting monitoring; the present invention also carries out anti-interference processing to the image, and the characteristics of the shadow characteristics produced by the object and the swing of objects such as trees in the judgment image are eliminated by the light, and the landslide monitoring method based on image processing is solved. The difficulty of being easily disturbed and causing misjudgment

Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] Such as figure 1 As shown, the present invention discloses an anti-jamming landslide monitoring method based on image processing, comprising the following steps:

[0048] (1) Obtain the monitoring image sequence taken by the image acquisition device at a preset frequency. The monitoring image sequence includes a plurality of monitoring images, and each monitoring image includes a reference target image and a mountain image to be monitored; the reference target image is an image acquisition The image of the target object fixedly arranged in the shooting scene of the mountain to be monitored captured by the device;

[0049] (2) Perform the first de-interference processing on all monitoring images, and obtain the pixel point set P of the non-shadow area of ​​each monitoring image i ;

[0050] (3) Comparing the monitoring image with the monitoring image...

Abstract

The invention discloses an anti-interference landslide monitoring method based on image processing. By setting a reference target, the problem that the image acquisition device is affected by the offset of the image acquisition device due to thermal expansion and cold contraction of a stent or other reasons is solved; The image is subjected to anti-interference processing to remove the shadows caused by illumination and the influence of object swinging on the image, and solve the problem that the landslide monitoring method based on image processing is prone to interference and misjudgment. The method of the invention has the advantages of low hardware cost, wide monitoring coverage and strong anti-interference ability.

Description

technical field [0001] The invention relates to the technical field of landslide monitoring, in particular to an anti-interference landslide monitoring method based on image processing. Background technique [0002] my country's terrain is complex, there are many mountainous areas, and landslide disasters occur frequently. It is very necessary to study how to effectively monitor the mountains. At present, there are three main methods of landslide monitoring at home and abroad. [0003] One is sensor monitoring. This application refers to the monitoring of landslides by deploying a variety of sensors on the slope to collect landslide data. This application can realize on-site data collection and remote monitoring of real-time conditions of landslides. However, it needs to deploy a variety of sensors at appropriate locations on the mountain. The deployment is complicated, the implementation is limited by geography, and the cost of equipment is high. [0004] The second is r...
