| 中文摘要: |
| 在地下暗挖施工过程中，盾构机的掘进路线必须在设计误差要求范围内，因此实时监控盾构的运动状态至关重要。作为盾构机眼睛的导向系统要求高精度、实时快速地测量出盾构的位置和姿态。基于嵌入式技术设计的激光位移检测靶主要由CCD照相机、倾角传感器和棱镜等光学元件组成，结合全站仪和后视棱镜，通过CCD采集全站仪发射的激光光斑，对光斑图像进行去噪、形态学等处理，准确计算中心点坐标，通过坐标系的转换，最终实现对盾构的滚动角、方位角和俯仰角的测量。 |
| 英文摘要: |
| In the process of underground excavation, shield tunneling route must be within the scope of the design error. So it is very important to monitor the real-time motion state of shield. The guidance system is the eye of shield and it can measure the real-time position and orientation of shield precisely and rapidly. The system of laser displacement detection target based on embedded technology is composed of CCD cameras, tilt sensors and optical prism components. The system, with total stations and rear prisms, collects the laser spot emitted by total station through CCD, conducts denoising and morphological processing of the spot image, accurately calculates the coordinates of the center point and finally obtains the rolling angle, azimuth angle and pitch angle of the shield through the transformation of the coordinate system. |
