On-barn pig weight estimation based on body measurements by structure-from-motion (SfM) [PDF]
, 2018 Information on the body shape of pigs is a key indicator to monitor their performance and health and to control or predict their market weight. Manual measurements are among the most common ways to obtain an indication of animal growth.

STUDY ON IMPROVEMENT OF ACCURACY IN INERTIAL PHOTOGRAMMETRY BY COMBINING IMAGES WITH INERTIAL MEASUREMENT UNIT [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Inertial photogrammetry is defined as photogrammetry that involves using a camera on which an inertial measurement unit (IMU) is mounted. In inertial photogrammetry, the position and inclination of a shooting camera are calculated using the IMU.

Monitoring ephemeral river changes during floods with SfM photogrammetry
Journal of Iberian Geology, 2018 [ES]: Para llegar a comprender el comportamiento morfosedimentario de los ríos es necesario realizar un seguimiento detallado de los cambios topográficos que tienen lugar en sus cauces. Sin embargo, cuanto mayor es la resolución de la técnica utilizada para la reconstrucción topográfia, el coste y el tiempo necesario para cubrir una cierta superficie ...

Structure-from-Motion Using Historical Aerial Images to Analyse Changes in Glacier Surface Elevation
Remote Sensing, 2017 The application of structure-from-motion (SfM) to generate digital terrain models (DTMs) derived from different image sources has strongly increased, the major reason for this being that processing is substantially easier with SfM than with conventional ...

Microscopic Structure from Motion (SfM) for Microscale 3D Surface Reconstruction
Sensors, 2020 In microscale photogrammetry, the confocal microscopic imaging technique has been the dominant trend. Unlike the confocal imaging mostly for transparent objects, we propose a novel method to construct a 3D shape in microscale for various micro-sized ...

UAV Video-Based Approach to Identify Damaged Trees in Windthrow Areas
Remote Sensing, 2022 Disturbances in forest ecosystems are expected to increase by the end of the twenty-first century. An understanding of these disturbed areas is critical to defining management measures to improve forest resilience.

Terrain changes from images acquired on opportunistic flights by SFM photogrammetry [PDF]
The Cryosphere, 2016 Abstract. Structure from motion (SfM) photogrammetric techniques are emerging as powerful tools for surveying, at very high spatial and temporal resolution, geomorphological objects undergoing relatively rapid change, such as glaciers, moraines, or landslides. Modern software and computing power allows production of accurate data from low-cost surveys,
