Problems solved by technology

The mountainous area label insertion method requires professionals to operate, and the process is extremely complicated. It is necessary to send manpower to the mountain area to insert the marker, and the input of manpower and material resources is large, and the technical means are single. Only a few hard-hit areas are suitable for monitoring by this method.
However, general image analysis can only make a preliminary judgment on the creep change of landform, and it is impossible to accurately judge whether the landform has actually undergone creep change only from the change of image.

Abstract

The invention discloses a landform latent change observation device utilizing an image processing technology, the landform latent change observation device comprises a camera device and a processing unit, the camera device performs image acquisition on landform to provide multi-period periodic images corresponding to the landform, the processing unit captures periodic images divided into a plurality of microcell areas, and calculates an average gray value of the periodic image of each microcell area, comparing the average gray value of the periodic image of the current microcell area with theaverage gray value of the periodic image of the early-stage microcell area to generate a gray difference degree, and generates landform latent change information when the gray difference degree is greater than a threshold value. Therefore, the landform latent change observation device utilizing the image processing technology can find the abnormal state of the surface appearance in advance, and further analyze and judge the specific latent change condition by utilizing the image processing technology, so that the occurrence of latent change disasters can be effectively prevented.

Description

technical field [0001] The invention relates to a landform creep observation device, in particular to a landform creep observation device using image processing technology. Background technique [0002] The occurrence of natural disasters may cause heavy casualties, property losses, ecological environment damage and serious social harm, and creep is one of the causes of natural disasters. [0003] Creeping catastrophes include landslides, avalanches, retaining walls, and deformation and collapse of similar engineering bodies. [0004] Among them, creep in landform is the main cause of landform change, and serious creep disasters may even cause loss of life and property. The subsurface creep will have subtle changes to the surface shape, and long-term monitoring of this subtle change will be an important means of preventing disasters caused by creep. [0005] At present, early warning measures for monitoring landform creep usually use a lot of manpower and various instrumen...
