Abstract
A method and a system for automatically collecting multiple information of a tunnel during construction period are provided. A detection point and a detection line are formed by projecting a light source on the inner wall of the tunnel, and then the pixel position changes of the areas where the detection point and the detection line are located in different time periods are recorded by a measuring camera, and the detection point and the detection line are integrated and corrected with tunnel point cloud data as a reference standard to form an accurate four-dimensional model of the tunnel.
