Problems solved by technology

[0005] At present, the early warning measures for monitoring landform creep usually use a lot of manpower and various instruments. The common monitoring method is the mountain label insertion method. This method requires professional operation, and the process is extremely complicated. The investment 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

Abstract

The invention discloses landform latent change observation equipment which comprises a camera device and a processing unit, the camera device collects images of a landform so as to provide multi-period periodic images corresponding to the landform, and the processing unit captures periodic images divided into a plurality of cell areas, calculates the periodic image of each cell region by using a hash algorithm to form a character string, compares the similarity between the character strings generated by the early-stage periodic image and the current-stage periodic image of the same cell region, and generates landform latent change information when the similarity is lower than a threshold value. Therefore, the landform latent change observation equipment can directly carry out rapid and comprehensive observation at a far end, and can find the abnormal state of the surface appearance in advance, thereby effectively preventing the occurrence of latent change disasters.

Description

technical field [0001] The invention relates to a landform creep observation device, in particular to a landform creep observation device capable of monitoring the occurrence of extensive landform creep. Background technique [0002] China's climate is changeable, the terrain is complex, and the ecological environment is fragile. It is one of the countries with the most serious natural disasters in the world. Frequent natural disasters have repeatedly tested the public security system and social security capabilities of the entire society. The release of natural disaster early warning information is an important part and basic work of the government's disaster prevention and mitigation work, and it has gradually attracted widespread attention. [0003] Creep in landform is the main cause of landform change, and severe 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...
