无人机摄影测量技术在数字化地形测量的应用探讨

Discussion on the Application of UAV Photogrammetry Technology in the Digital Topographic Survey

在工程测量领域,地形测量是非常重要的一项工作,即指的是对地形图进行测绘的作业,主要对地球表面的地物、地形处于水平面上的投影位置及高程进行测量,然后根据一定的比例缩小处理,进一步采取标记、符号的方式,将地形图绘制出来。该文重点分析探讨无人机摄影测量技术在数字化地形测量的具体应用要点,旨在全面提高数字化地形测量工作质量。

In the field of engineering survey,topographic survey is a very important work,that is to say,it refers to the mapping of topographic maps.It mainly measures the ground objects on the earth's surface,the projection position and elevation of the terrain on the horizontal plane,and then reduces the size according to a certain scale,and then draws the topographic map in the form of marks and symbols.This paper focuses on the application of UAV photogrammetry technology in digital topographic survey,aiming at improving the quality of digital topographic survey.
