Abstract
The present invention relates to a system for quickly detecting tunnel deformation, comprising a rail walking mechanism (1) disposed on a subway rail, and an acquisition system (2) disposed on the rail walking mechanism (1); wherein the rail walking mechanism (1) is a T-shaped walking platform, comprising a cross shaft (11), a longitudinal shaft (12) and a stand column (13); the cross shaft (11) and the longitudinal shaft (12) are connected to form the T-shaped platform; tread wheels (16) are disposed at the bottom of the T-shaped platform; one end of the stand column (13) is vertically connected with the cross shaft (11), and the other end of the stand column is used for configuring an operating platform (14) of the acquisition system (2); the acquisition system (2) comprises a fractional laser structured light source (21), industrial focus-fixed cameras (22) and a computer; and the computer is connected with the industrial focus-fixed cameras (22). Compared with the prior art, the quick detection device can effectively solve the problem of detecting cross section deformation of tunnels, the problem of transforming many different local coordinate systems to a global coordinate system, and the problem of unstable test data caused by movements.
