摘要：地面三维激光扫描技术属于新型的测量手段，相较于以往的单点测量方法具有多方面的优势。单点测量范围相对较小，并且测量精度有限，同时单点测量技术的覆盖范围小，测量效率低。而地面三维激光扫描技术的应用则实现了从点上测量到面上测量的转变，因此测量精度更高，数据获取速度更高。该技术还可以实现非接触测量，因此能够满足那些复杂地形的测量工作，并且可以更好地保障工作人员的人身安全。正是因为这些方面的优势，使得地面三维激光扫描技术在地质调查中的应用十分广泛，可以为地质调查工作提供有力的支持，可以在很大程度上提升地質调查工作的质量和效率。基于此，本文就地面三维激光扫描技术在地质调查中的应用进行探究，仅供大家参考。

Abstract： The terrestrial 3D laser scanning technology is a new type of measurement method， which has many advantages compared with the previous single-point measurement methods. The single-point measurement range is relatively small and the measurement accuracy is limited. At the same time， the single-point measurement technology has a small coverage area and low measurement efficiency. The application of terrestrial 3D laser scanning technology has realized the transformation from point measurement to surface measurement， so the measurement accuracy is higher and the data acquisition speed is higher. The technology can also achieve non-contact measurement， so it can meet the measurement work of those complex terrain， and can better protect the personal safety of the staff. It is precisely because of these advantages that terrestrial 3D laser scanning technology is widely used in address surveys， which can provide strong support for geological survey work， and can greatly improve the quality and efficiency of geological survey work. Based on this， this article explores the application of terrestrial 3D laser scanning technology in geological surveys for your reference only.
