抽象的。运动结构 (SfM) 摄影测量是一种灵活而强大的工具，可提供描述物体表面的 3D 点云。由于激光扫描技术易于运输且所需设备成本低廉，SfM摄影测量在恶劣的高山环境中具有巨大的应用潜力。这里需要点云和衍生副产品（DEM、正射影像、虚拟现实模型）来记录表面形态并研究动态过程，例如山体滑坡、雪崩、河流和土壤侵蚀、冰川退缩。另一方面，从文献和作者的直接经验来看，仍有一些技术问题值得深入研究。本文希望解决一些悬而未决的问题并提出解决方案，特别是在摄影测量网络设计、最终产品地理配准策略以及时间比较方面。讨论记录了一些例子，主要来自意大利阿尔卑斯山福尔尼冰川的测量活动。
Abstract. Structure-from-Motion (SfM) photogrammetry is a flexible and powerful tool to provide 3D point clouds describing the surface of objects. Due to the easy transportability and low-cost of necessary equipment with respect to laser scanning techniques, SfM photogrammetry has great potential to be applied in harsh high-mountain environment. Here point clouds and derived by-products (DEM’s, orthoimages, Virtual-Reality models) are needed to document surface morphology and to investigate dynamic processes such as landslides, avalanches, river and soil erosion, glacier retreat. On the other hand, from both the literature and the direct experience of the authors, there are some technical issues that still deserve thorough investigations. The paper would like to address some open problems and suggest solutions, in particular on regards of the photogrammetric network design, the strategy for georeferencing the final products, and for their comparison within time. The discussion is documented with some examples, mainly from surveying campaigns at the Forni Glacier in Italian Alps.
