Description

technical field [0001] The invention relates to the technical field of deformation observation of the surface area, in particular to a wireless laser matrix monitoring system and method for deformation observation of the surface area. Background technique [0002] Continuous observation of surface deformation in mining subsidence areas, landslide areas, and fissure areas is one of the effective ways to predict geological disasters such as mining area subsidence, landslides, and fissures. [0003] At present, two methods are usually used for automatic monitoring of mining subsidence areas, landslides, and cracked surfaces: one method is to use contact-type on-site monitoring instruments, such as pull rods, pull-rope displacement meters, magnetic extensometers, etc., combined with remote network The transmission module can realize real-time deformation monitoring of the surface area, but the disadvantage of this method is that it can only measure a single point at a time, and ...
