机载激光雷达技术在山区地形测绘中的应用

Application of Airborne Lidar Technology in Mountain Topography Surveying and Mapping

在对山区地形进行测绘的过程中,很容易受到地形条件、通讯信号以及交通形式等诸多因素的掣肘,工作的难度系数比平原地形的要大得多,不仅要遵循一般的测量规程,还要结合实际,充分考虑该地区具体特点才能确保测量工作的顺利开展。近年来,随着科技水平的不断提高,出现了很多新型的测量技术,例如激光雷达、无人机等,通过使用这些更加先进的仪器和技术手段,既能解决常规方式在测量山区复杂地形中精度无法保证、效率难以提高的问题,也能有效降低作业中事故发生的概率,为测量人员的安全提供了有力保障。基于此,本文对将机载激光雷达技术合理应用到山区的地形测绘工作中进行了研究,希望能够有一定的参考价值。

In the process of surveying and mapping mountain terrain,it is easy to be constrained by many factors such as terrain conditions,communication signals and traffic forms.The difficulty coefficient of the work is much greater than that of plain terrain.It is not only necessary to follow general measurement procedures,but also necessary to combine reality and fully consider the specific characteristics of the area to ensure the smooth development of the survey work.In recent years,with the continuous improvement of the level of science and technology,many new measurement technologies have emerged,such as lidar,unmanned aerial vehicles,etc.By using these more advanced instruments and technical means,it can solve the problem of conventional methods in measuring complex terrain in mountainous areas.The problem that accuracy cannot be guaranteed and efficiency is difficult to improve can also effectively reduce the probability of accidents during operation and provide a strong guarantee for the safety of surveying personnel.Based on this,this article studies the rational application of airborne lidar technology to terrain surveying and mapping in mountainous areas,hoping to have a certain reference value.
