SfM-photogrammetry for fast recording of archaeological features in remote areas

open access: yesArcheologia e Calcolatori, 2020
Digital documenting of archaeological evidence represents a crucial tool in the study, preservation, management, and promotion of archaeological sites in remote regions and in fragile landscapes. In fact, in marginal environment, the knowledge related to archaeological heritage can quickly disappear, especially when policies to protect cultural ...

Quantifying Tufa Growth Rates (TGRs) using Structure-from-Motion (SfM) Photogrammetry

open access: yesProceedings of the 6th International Conference on Geographical Information Systems Theory, Applications and Management, 2020
The production of high-quality digital surface models (DSMs) is an increasing interest throughout the various geomorphometry studies. Consequently, a wide range of advanced geospatial methods has been used at different scales. Despite the fact that Structure-from-Motion (SfM) photogrammetry is one of the most popular methods until now it has not been ...

Evaluating the Potentiality of Using Control-free Images from a Mini Unmanned Aerial Vehicle (UAV) and Structure-from-Motion (SfM) Photogrammetry to Measure Paleoseismic Offsets

open access: yes, 2021
Paleoseismic offsets are important parameters for evaluating fault activity. With the development and popularization of unmanned aerial vehicles (UAVs) and structure-from-motion (SfM) photogrammetry, more and more low-cost mini-UAVs have been used for ...

A CRITERION OF RADIAL DISTORTION ON STRUCTURE FROM MOTION WITH CONSUMER-GRADE CAMERAS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Images from consumer-grade cameras typically contain significant radial distortions, resulting in less accurate photogrammetry results generated using Structure from Motion (SfM). It is prone to reconstruct inaccurate scene points, becoming the so-called

Photogrammetric 3D Model via Smartphone GNSS Sensor: Workflow, Error Estimate, and Best Practices

open access: yesRemote Sensing, 2020
Geotagged smartphone photos can be employed to build digital terrain models using structure from motion-multiview stereo (SfM-MVS) photogrammetry. Accelerometer, magnetometer, and gyroscope sensors integrated within consumer-grade smartphones can be used
