The application discloses a tunnel three-dimensional deformation monitoring method and related devices, which are applied to a camera measurement system including at least two series camera observation station networks. The method includes: obtaining the shaking amount of each camera observation station through multiple reference transfer cameras; Correct the initial position and attitude of each camera observation station relative to the global coordinate system according to the shaking amount of each camera observation station, and obtain the final position and attitude of each camera observation station; through at least two series camera observation stations in the same network The two measurement camera arrays of the camera observation station group perform forward intersection measurement on the corresponding multiple points to be measured, and obtain multiple three-dimensional coordinates, and the multiple points to be measured are within the operating range of the tunnel to be measured; according to any two moments, the All three-dimensional coordinates of determine the three-dimensional deformation of the tunnel under test between any two moments. Adopting the embodiment of the present application helps to improve the accuracy of tunnel three-dimensional deformation measurement.
Description
technical field [0001] The present application relates to the technical field of tunnel monitoring, in particular to a tunnel three-dimensional deformation monitoring method and related devices. Background technique [0002] Currently, tunnel three-dimensional deformation monitoring methods include contact measurement methods and non-contact measurement methods. Since both the contact measurement method and the non-contact measurement method only consider the influence of the three-dimensional deformation of the tunnel, the accuracy of the tunnel three-dimensional deformation monitoring method for the measurement of the three-dimensional deformation of the tunnel needs to be further improved. Contents of the invention [0003] Embodiments of the present application provide a method for monitoring three-dimensional deformation of a tunnel and a related device, which are used to improve the accuracy of measuring three-dimensional deformation of a tunnel. [0004] In the fir...
