Steel structure deformation repairing method and device based on image recognition

Abstract

The invention discloses a steel structure deformation repairing method and device based on image recognition, and relates to the technical field of image recognition processing, and the method comprises the steps: carrying out the multi-modal feature extraction of the surface of a steel structure according to a displacement sensor signal; performing definition optimization on the steel structure deformation area image, and configuring a deformation visual feature vector; decomposing signals of the displacement sensor, and extracting energy characteristics of different stress frequency bands; fusing and introducing an attention mechanism to dynamically focus the key deformation region, and outputting a quantitative evaluation result; and when the quantitative evaluation result meets a repair threshold condition, triggering a repair instruction and linking the repair equipment to execute a repair operation. The technical problems that in the prior art, spatial form perception and mechanical state information are lacked, local deformation and stress are difficult to capture, and evaluation dimensions are not comprehensive and accurate enough are solved, and the technical effects that all-directional accurate quantitative evaluation and intelligent linkage repair of the steel structure are achieved, and the maintenance efficiency and reliability of the structure are improved are achieved.
