Abstract

In the process of tunnel excavation, in order to ensure the error between the direction of travel and the designed tunnel axis within required range, the relationship between the position of the shield and the designed axis of the tunnel should be monitored and measured in real time. The laser displacement detection target based on embedded technology is an important part of the shield laser guidance. It can perform the measurement of the position and angle of the shield by the internal CCD camera, tilt sensor and prism. The laser detection target is fixing on the shield. The total station can calculate the spatial position coordinates of prism which is on the laser target by visual reference. The laser target can get the shield attitude angle. The shield tail incision center coordinates can be obtained by coordinate conversion.
