Assessment of photogrammetric mapping accuracy based on variation ground control points number using unmanned aerial vehicle
TL;DR: In this paper, the influence of the number of ground control points used for georeferencing on Digital Surface Model and orthoimage accuracies obtained with UAV-photogrammetry is analyzed.
Journal ArticleDOI
Assessment of UAV-photogrammetric mapping accuracy based on variation of ground control points
Patricio Martínez-Carricondo,Francisco Agüera-Vega,Fernando Carvajal-Ramírez,Francisco Javier Mesas-Carrascosa,Alfonso García-Ferrer,Fernando-Juan Pérez-Porras +5 more
TL;DR: It is necessary to place GCPs around the edge of the study area to minimize planimetry errors and to create a stratified distribution inside theStudy area with a density of around 0.5–1 GCP × ha−1 to minimize altimetryerrors.
Journal ArticleDOI
Accuracy of Digital Surface Models and Orthophotos Derived from Unmanned Aerial Vehicle Photogrammetry
TL;DR: In this paper, the influence of flight altitude, terrain morphology, and the number of ground control points (GCPs) on digital surface model (DSM) and orthoimage accuracies obtained with UAV photogrammetry was explored.
Journal ArticleDOI
Reconstruction of extreme topography from UAV structure from motion photogrammetry
Francisco Agüera-Vega,Fernando Carvajal-Ramírez,Patricio Martínez-Carricondo,Julián Sánchez-Hermosilla López,Francisco Javier Mesas-Carrascosa,Alfonso García-Ferrer,Fernando Juan Pérez-Porras +6 more
TL;DR: In this article, a software program was developed to generate contour lines and cross-sections derived from the point cloud, which was able to represent all terrain geometric characteristics, such as several Z coordinates for a given planimetric (X, Y) point.
Journal ArticleDOI
UAV Photogrammetry Accuracy Assessment for Corridor Mapping Based on the Number and Distribution of Ground Control Points
Ezequiel Ferrer-González,Francisco Agüera-Vega,Fernando Carvajal-Ramírez,Patricio Martínez-Carricondo +3 more
TL;DR: The purpose of this work consists of determining the number of GCPs and how to distribute them in a way that yields higher accuracy for a corridor-shaped study area, and finding optimal results regarding fieldwork cost.
