Abstract

The invention discloses an earth and rockfill dam deformation monitoring method and system based on a corner reflector and a storage medium. The method comprises the steps of: obtaining an SAR image containing a target corner reflector which is disposed on the surface of a dam body of an earth and rockfill dam and located at a target point of the surface of the dam body; determining pixel positioninformation and sub-pixel position information of the target corner reflector in the SAR image based on the SAR image; determining a deformation sequence corresponding to a target point on the surface of the dam body based on the pixel position information and the sub-pixel position information of the target corner reflector in the SAR image; and monitoring the deformation of the target point onthe surface of the dam body based on a plurality of deformation sequences corresponding to the position of the corner reflector so as to monitor the deformation of the surface of the dam body in the vertical direction and the direction perpendicular to the axis of the dam.

Description

technical field [0001] The invention relates to the technical field of deformation monitoring of earth-rock dams, in particular to a method, system and storage medium for monitoring deformation of earth-rock dams based on corner reflectors. Background technique [0002] According to the 2017 National Statistical Bulletin on Water Conservancy Development, 98,795 reservoirs of various types have been built across the country. According to the survey data of small reservoirs, 49.60% have water level observation, 6.50% have seepage monitoring, 3.09% have seepage monitoring, and 9.03% have deformation monitoring. In addition to a huge number of reservoir projects in my country, there are 312,000 kilometers of river embankments, as well as a large number of lock chambers and pumping stations. For the widely distributed and large number of water conservancy projects, the traditional monitoring technology has the disadvantages of low monitoring efficiency and high monitoring cost, ...
