The invention discloses a method, a medium and equipment for monitoring tunnel deformation, and the method comprises the steps: collecting structured light images of a primary support region and a tunnel face region of a tunnel through an image collection system, carrying out the feature matching of the structured light images, calculating the three-dimensional coordinate information of feature points on the structured light images, and combining with time information to obtain the deformation of the tunnel. The structured light image is compared with the reference image to obtain a three-dimensional deformation vector, then deformation displacement of feature points is calculated, tunnel structure three-dimensional space-time deformation big data is formed, the deformation evolution trend of an initial support area and the stable state of a tunnel face area are analyzed, the stability of the initial support area and the stability of the tunnel face area are predicted, and safety protection in the tunnel cons
