Abstract

The invention provides a tunnel convergence deformation detection method and system based on a visual image and relates to the tunnel deformation detection technology field. A camera system and a detection target are included. The camera system shoots an initial section image of a tunnel section to be detected, and sends the initial section image to an external system for processing to obtain a standard convergence parameter of the tunnel section. The external system generates a corresponding detection signal according to a detection requirement, and sends the detection signal to the camera system. The camera system shoots a real-time section image of the tunnel section according to the detection signal, and transmits the real-time section image to the external system. The external systemcarries out processing according to the real-time section image and the standard convergence parameter to obtain a real-time convergence detection result. In the invention, the structure is simple, anoccupied tunnel area is small and the cost is low. A tunnel convergence deformation condition during construction and operation can be obtained in real time to ensure the safety of a tunnel structure.

Description

technical field [0001] The present invention relates to the technical field of tunnel deformation detection, in particular to a tunnel convergence deformation detection method and system based on visual images. Background technique [0002] In recent years, with the acceleration of national infrastructure construction, my country's tunnel construction has entered a period of rapid development, and various tunnel accidents have also occurred frequently. The conditions of engineering geology and hydrogeology of the mountain that the tunnel crosses are complex and changeable. During the construction and operation of the tunnel, the continuous detection of the deformation of the tunnel structure is an important guarantee for the safety of the tunnel. The so-called tunnel convergence deformation refers to the deformation of the cross-sectional shape of the tunnel due to the influence of factors such as the ground, surrounding building loads, tunnel engineering structure construct...
