    • 摘要: 滑坡灾害是中国最常见的地质灾害之一,严重威胁人民生命财产安全,实现数字滑坡的高效、便捷和准确是滑坡防灾减灾的关键环节。近年来,由于高效率和低成本等优势,免像控无人机航测技术已被逐渐应用于数字滑坡分析领域。本文旨在为探讨基于免像控技术的各航测软件在滑坡地形处理中的优劣势,以及应用于数字滑坡技术中的可行性。本研究选取长江三峡库区的大型黄土坡滑坡为研究对象,借助大疆PHANTOM 4RTK无人机获取研究区高分辨率遥感数据,采用四款国内外常用的专业航测处理软件Pix4D mapper、Photoscan、Context Capture以及DJI Terra分别进行数字化处理,并从正射图质量、精度误差、耗时及操作难度四个维度进行对比分析并应用。研究结果表明:(1)在单体滑坡航拍面积高达2.23 km2的情况下,Pix4D mapper软件生成的正射图质量效果最好且能达到大比例尺制图要求;(2)在精度误差上,DJI Terra与Pix4D mapper表现最好,其中20个检查点的平面中误差均未超过10 cm,垂直中误差均未超过30 cm,综合对比结果发现在较大面积的单体滑坡灾害分析中Pix4D mapper软件最具优势;(3)基于数字滑坡图件遥感解译获取了滑坡基本数字信息并通过GIS软件将滑坡数字信息储存起来建立滑坡灾害大数据库。综上,免像控无人机航测技术在今后的滑坡灾害大数据库的快速建立具有巨大优势并将成为重要的研究方向之一,为滑坡灾害防治与应急调查快速分析提供技术与数据支撑。

       

      Abstract: Landslide disasters are among the most prevalent geological hazards in China, which seriously threatens the safety of people's lives and property. Efficient, convenient, and accurate digital landslide analysis is crucial for landslide disaster prevention and mitigation. In recent years, image-free unmanned aerial vehicle (UAV) aerial survey technology has been increasingly employed in digital landslide analysis due to its advantages of high processing efficiency and production of high-quality maps. This study aims to explore the advantages and disadvantages of various aerial survey software based on image-free control technology in landslide terrain processing, as well as their feasibility in digital landslide applications. In this paper, the Huangtupo landslide in the Three Gorges reservoir area of the Yangtze River is selected as the research object. High-resolution remote sensing data in the study area are obtained using the Dajiang PHANTOM 4RTK UAV. Four commonly used professional aerial survey processing software, namely Pix4D Mapper, Photoscan, Context Capture, and DJI Terra, are utilized for digital processing. A comparative analysis is conducted based on four aspects: orthophoto quality, accuracy error, time consumption, and operation difficulty. The research findings reveal that: (1) Under the condition of a single landslide aerial photography area of up to 2.23 km2, Pix4D Mapper software generates orthophoto maps of the highest quality that meet the requirements for large-scale mapping; (2) DJI Terra and Pix4D Mapper have the best performance in terms of accuracy error, with the mean square error of 20 inspection points in the plane and vertical axis not exceeding 10cm and 30cm, respectively. Comprehensive comparison results indicate that Pix4D Mapper software demonstrates the most advantages in analyzing large-scale individual landslide disasters; (3) Based on the remote sensing interpretation of digital landslide maps, the basic digital information of the landslide is obtained, and a comprehensive landslide disaster database is established by storing the digital landslide information using GIS software. In conclusion,, image-free UAV aerial survey technology holds significant advantages in the rapid establishment of future landslide disaster databases, emerging as an important research direction that provides technical and data support for swift analysis of landslide disaster prevention and emergency investigations.
