摘要
为了快速获取大比例尺地形图、三维实景模型等数字化成果,提出了一种基于无人机倾斜摄影测量技术的测量方法:采用Context Capture Center软件进行空中三角测量;重建三维实景模型;采用Mapmatrix3D软件进行三维实景模型内业制图;外业补充调绘;最终得到全要素的1∶500数字线划图。通过工程案例验证了该技术效率高、精度可靠、成果丰富。该技术在工程中的应用实践为同类项目的开展提供了有益的参考。
In order to quickly obtain the digital results of large-scale topographic maps and three-dimensional real scene models a measurement method based on unmanned aerial vehicle oblique photogrammetry technology is proposed the Context Capture Center software is used for aerial triangulation Reconstruction of three-dimensional real scene model Mapmatrix3 d software is used for interior mapping of three-dimensional real scene model Field supplementary mapping Finally the 1∶500 digital line graph of all elements is obtained.The engineering case verifies that the technology has high efficiency reliable accuracy and rich achievements.The application practice of this technology in engineering provides a useful reference for the development of similar projects.
