Claim 2:
3. The method for the real-time monitoring of the tunnel deformation according to claim 2, wherein in the S34, a method for detecting the states of the tunnel structure by the data processing unit comprises:
S341, dividing each section of a tunnel wall into left and right side walls and a vault, detecting lateral and longitudinal displacements of the left and right side walls, and detecting the longitudinal displacements of the vault;
S342, matching the center lines of the extracted structured light curves with the reference lines, and analyzing changes of pixel displacements;
S343, detecting the integral settlement of the multi-section of the tunnel by combining a matching structure of the center lines of the plurality of structured light curves from the front to the back of the tunnel to determine an overall downward shift of the plurality of curves as an indication of a disease of the integral settlement of the multi-section of the tunnel; and
S344, performing spatial mapping of a settlement amount, converting the pixel displacements into spatial offset distances through pixel quantization to obtain an actual settlement amount and an actual convergence amount, and determining a disease type according to a displacement direction.
