摘要
通过研究无人机实景三维测绘技术的原理与方法,分析了实景三维测绘技术在地质勘查和地灾分析中的重要作用,并以“KD新农村建设项目”为例,说明了通过合理的航测路径规划、采集数据预处理、建模模块选择,可以准确高效地建立实景三维模型。该实景三维技术在地质灾害前期勘查、隐患跟踪分析、高精度等高线生成等方面具有突出作用。最后论证了无人机实景三维技术在地质勘查工作上具有一定的应用前景,可以大幅提高地质灾害分析的质量与效率。
This paper studies the principle and method of UAV real scene three-dimensional mapping technology,analyzes the important role of real scene three-dimensional mapping technology in geological survey and geological disaster analysis.Taking“KD new rural construction project”as an example,it shows that through reasonable aerial photography route planning,data acquisition pre-processing and modeling module selection,the real scene 3D model can be established accurately and efficiently.It plays an important role in pre-disaster investigation,post-disaster tracking analysis and high-accuracy contour generation.This paper demonstrates that UAV real scene 3D technology has a very high application prospect in geological investigation,which can greatly improve the quality and efficiency of geological hazard analysis.
