三维激光扫描技术在地下探测中的应用研究
A Research of 3D Laser Scanning Technology Applied in Subsurface Exploration
【摘要】 三维激光扫描技术克服了传统测量的局限性,在测量领域具有广阔的前景。介绍了采用三维扫描技术获取点云,以单站拟合方式获得码头斜桩可见部分的高精度三维姿态,进而预测斜桩深埋土中48 m不可见部分的三维坐标。结果表明通过灵活运用三维扫描技术,可以完成常规测量技术难以完成的工作。
【Abstract】 3D laser scanning technology can overcome the limitation of traditional survey methods with a wide application in the field of survey.How to get point clouds by 3D laser scanning technology is introduced mainly in this paper.High-accuracy 3D gesture of the visible dock oblique pile is obtained in the method of single station fitting,and then,3D coordinates of the invisible oblique pile underground 48 m can be predicted.The results show that professionals can finish the work(which is difficult to complete through common methods) by means of 3D laser scanning technology.
