Landslide displacement monitoring method and device based on GNSS antenna and MEMS

The embodiment of the invention discloses a landslide displacement monitoring method and equipment based on a GNSS antenna and an MEMS. The dangerous degree of landslide of a tower can be determined more accurately. The embodiment of the invention is applied to landslide displacement monitoring equipment. The landslide displacement monitoring equipment comprises a global navigation satellite system (GNSS) antenna and a micro electro mechanical system (MEMS), the landslide displacement monitoring equipment is arranged on a target tower, and the target tower is further provided with at least three cameras; the GNSS antenna is used for acquiring GNSS observation data; the MEMS comprises an attitude sensor; the method comprises the following steps: acquiring first GNSS observation data acquired by a GNSS antenna, and receiving second GNSS observation data sent by a base station; images, corresponding to a landslide area around the target tower, collected by at least three cameras are obtained, attitude data, coll
