Uav Photogrammetry: Block Triangulation Comparisons
UAVs systems represent a flexible technology able to collect a big amount of high resolution information, both for metric and interpretation uses. In the frame of experimental tests carried out at Dept. ICA of Politecnico di Milano to validate vector-sensor systems and to assess metric accuracies of images acquired by UAVs, a block of photos taken by a fixed wing system is triangulated with sev...
متن کاملEstimating the Rut Depth by UAV Photogrammetry
The rut formation during forest operations is an undesirable phenomenon. A methodology is being proposed to measure the rut depth distribution of a logging site by photogrammetric point clouds produced by unmanned aerial vehicles (UAV). The methodology includes five processing steps that aim at reducing the noise from the surrounding trees and undergrowth for identifying the trails. A canopy he...
متن کاملMeasuring Vegetation Height in Linear Disturbances in the Boreal Forest with UAV Photogrammetry
Monitoring vegetation recovery typically requires ground measurements of vegetation height, which is labor-intensive and time-consuming. Recently, unmanned aerial vehicles (UAVs) have shown great promise for characterizing vegetation in a cost-efficient way, but the literature on specific methods and cost savings is scant. In this study, we surveyed vegetation height on seismic lines in Alberta...
متن کاملKinematic analysis of sea cliff stability using UAV photogrammetry
13 Erosion and slope instability poses a significant hazard to communities and 14 infrastructure located is coastal areas. We use point cloud and spectral data derived from close 15 range digital photogrammetry to perform a kinematic analysis of chalk sea cliffs located at 16 Telscombe, UK. Our data were captured from an unmanned aerial vehicle (UAV) and cover a 17 cliff face that is about 750 ...
متن کاملPerformance Evaluation of 3d Modeling Software for Uav Photogrammetry
UAV (Unmanned Aerial Vehicle) photogrammetry, which combines UAV and freely available internet-based 3D modeling software, is widely used as a low-cost and user-friendly photogrammetry technique in the fields such as remote sensing and geosciences. In UAV photogrammetry, only the platform used in conventional aerial photogrammetry is changed. Consequently, 3D modeling software contributes signi...
