The invention relates to the technical field of construction period tunnel monitoring, in particular to an automatic collection method and system for multivariate information of a construction period tunnel, and the method comprises the steps: forming a detection point and a detection line through the projection of a light source on the inner wall of the tunnel, and recording the pixel position changes of the areas where the detection point and the detection line are located in different time periods through a measurement camera; according to the invention, the detection point and the detection line are used as the reference and are integrated and corrected with the tunnel point cloud data to form an accurate tunnel four-dimensional model, so that the structural state and the construction progress of the tunnel can be dynamically observed and recorded in all directions, automation and intelligence of tunnel information collection are realized, manpower is saved, and the efficiency of tunnel construction is im
