Building deformation monitoring method and device and storage medium

Abstract

The invention discloses a building deformation monitoring method and device and a storage medium, and the method comprises the steps: acquiring a plurality of building images which are shot by a camera at the current moment and contain markers, carrying out preprocessing, extracting marker images, carrying out the maximum gradient projection calculation of the marker images, and obtaining the maximum gradient projection image of the markers; obtaining an integer pixel edge image of the marker according to the maximum gradient projection image of the marker; obtaining a sub-pixel edge image of the marker according to the integer pixel edge image; locating the center of the marker according to the sub-pixel edge images of the plurality of markers so as to obtain the center coordinate of the marker; and calculating the deformation of the building according to the center coordinate of the marker at the current moment and the center coordinate of the marker at the previous moment. According to the invention, problems of low efficiency, difficulty in guaranteeing precision and poor timeliness of operation means during deformation monitoring of the building at present are solved.

Description

Technical field [0001] The present invention relates to the field of building safety monitoring technology, particularly relates to a building deformation monitoring method, device and storage medium. Background technique [0002] Engineering building its own weight, load, lift the water table, insufficient geological exploration, design errors, construction quality and other reasons, likely to lead to building deformation. Therefore, regular building deformation monitoring is to ensure stability and security building an essential engineering tasks. [0003] Currently, deformation monitoring practical application mostly used "artificial + measuring instrument" mode, means low operating efficiency, difficult to ensure accuracy, timeliness difference. Despite the prior art deformation monitoring based on image processing technology, but mostly limited to indoor or super-computer simulation image captured near the target deformation calculation, a small amount may be practical image...
