Abstract

Landslides represent great dangers that can cause fatalities and huge property damage. To prevent or reduce all possible consequences that landslides cause, it is necessary to know the kinematics of the surface and undersurface sliding masses. Geodetic surveying techniques can be used for landslide monitoring and creating a kinematic model of the landslide. One of the most used surveying techniques for landslide monitoring is the photogrammetric survey by Unmanned Aerial System. The results of the photogrammetric survey are dense point clouds, digital terrain models, and digital orthomosaic maps, where landslide displacements can be determined by comparing these results in two measurement epochs. This paper presents a new data processing method with a novel approach for calculating landslide displacements based on Unmanned Aerial System photogrammetric survey data. The main advantage of the new method is that it does not require the production of dense point clouds, digital terrain models, or digital orthomosaic maps to determine displacements. The applicability and accuracy of the new method were tested in a test field with simulated displacements of known values within the range of 20-40 cm in various directions. The new method successfully determined these displacements with a 3D accuracy of ±1.3 cm.

基于无人机系统摄影测量的滑坡监测新方法

山体滑坡代表着巨大的危险，可以造成人员伤亡和巨大的财产损失。为了防止或减少滑坡可能造成的一切后果，有必要了解地表和地下滑动体的运动学。大地测量技术可用于滑坡监测和建立滑坡的运动学模型。无人机摄影测量是滑坡监测中最常用的测量技术之一。摄影测量调查的结果是密集的点云、数字地形模型和数字正射影图，其中可以通过比较两个测量时期的结果来确定滑坡位移。本文提出了一种新的数据处理方法，提出了一种基于无人机摄影测量数据的滑坡位移计算方法。新方法的主要优点是它不需要制作密集的点云、数字地形模型或数字正射影图来确定位移。在20 ~ 40 cm范围内的不同方向模拟位移值的试验场中，验证了新方法的适用性和准确性。新方法成功地确定了这些位移，三维精度为±1.3 cm。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
