顶管机自动导向水平角测量系统研究
Horizontal angle measurement of automatic navigation system of pipe jacking machine
摘要
设计了一套基于激光准直技术的顶管机自动导向水平角测量系统。系统具有两套光靶激光测量装置。利用具有漫反射特性的标靶接收准直激光, 标靶图像经CCD相机采集后处理得到标靶上的光点位置, 根据光点位置的变化可计算得出顶管机机头偏转的角度信息。研究了图像处理算法和角度计算算法, 并搭建了实验测试系统。实验结果表明, 在100m的测量距离内, 系统水平角测量范围可达到±1°, 测量精度为0.01°,可以满足顶管机地下施工水平方位角的测量要求。
Abstract
A horizontal angle measurement system based on laser techniques for automatic guiding system of the pipe jacking machine is proposed. A specially designed target that has a diffuse surface and a fixed shape is illuminated by laser beams. Pictures of the target are taken by an industrial camera from a predictable distance and orientation away and then processed and analyzed by a VC++ program to deduce the deflection angle of the pipe jacking machine in real time. System configuration and relevant image process algorithms optimally designed for the system is introduced in details. Experiment results show that, from a distance of 0 to 100 meters, the system gives a measuring range of ±1°and a measuring error of 0.01° which greatly meets the angle measuring requirement for underground guiding.
