Abstract

This application provides a dynamic moving monitoring tunnel deformation detection device and method based on dual vehicles, belonging to the field of rapid tunnel deformation detection technology. The detection device and method are based on a dual moving platform with a front vehicle and a rear vehicle. The front and rear vehicles rely on several RFID tags for flexible positioning and movement. From the initial position to the next measurement point within the visible distance, the visible laser rangefinder on the rear vehicle illuminates the laser positioning target of the front vehicle moving to the next measurement point and measures the precise distance between the two vehicles. The industrial vision analysis system of the front vehicle acquires the visible laser spot image on the laser positioning target and calculates the offset coordinates of the laser spot center on the laser positioning target. By dynamically measuring the predetermined tunnel range, the cross-sectional coordinates of the tunnel pipe at different time domains at the same location are calculated and compared to obtain the overall related deformation change of the tunnel pipe, thereby improving the efficiency and accuracy of tunnel deformation detection.
