A method and system for measuring deformation of infrastructure structures integrating Beidou and vision

Abstract

The invention discloses a method and system for measuring deformation of infrastructure structures integrated with Beidou and vision. At the first moment and the second moment, all the targets are photographed by the camera to obtain the first imaging image and the second imaging image, wherein the camera is located on the target facility, all the targets are in pairs, and each pair of targets is located at the target facility A local area; according to the first imaging image and the second imaging image, determine the relative distance variation of each pair of image points, wherein, a pair of image points corresponds to a pair of targets; acquire the camera at the first moment and the second According to the displacement data between time, the relative distance change of each image point is corrected according to the displacement data, and the corrected relative distance change of the image point is obtained; according to the relative distance change of each corrected image point, each local The structural deformation data of the region. The invention adopts the displacement data of the camera to carry out error adjustment, and can solve the problem of large error in the existing structure deformation measurement method.

Description

technical field [0001] The invention relates to the field of building measurement, in particular to a method and system for measuring deformation of infrastructure structures integrating Beidou and vision. Background technique [0002] Large-scale infrastructure such as bridges, tunnels, and highways bear a large amount of traffic loads, and the surrounding geological environment is constantly changing, resulting in uneven stress on bridges, tunnels, and highways at different locations, and structural deformations of varying degrees. If the structural deformation of the infrastructure is too severe, it may lead to major safety accidents such as bridge collapse, tunnel collapse, and road collapse. Therefore, it is necessary to monitor the structural deformation of large-scale infrastructure in time to detect abnormal structural deformation in time, provide support for the maintenance and renovation of infrastructure, and ensure the safety of the facility structure.
