ANTHROPOMETRIC MEASUREMENT BASED ON STRUCTURE FROM MOTION IMAGING TECHNIQUE

open access: yesПриборы и методы измерений, 2016
The aim of this work was to estimate limitations related of the actual resolution of images taken into the object reconstruction procedure (using Structure from Motion method) applied for anthropometric measurements. This is necessary to define technical

Towards a Mobile 3D Documentation Solution. Video-Based Photogrammetry and iPhone 12 Pro as Fieldwork Documentation Tools

open access: yesJournal of Computer Applications in Archaeology, 2023
New affordable equipment suitable for 3D fieldwork documentation has appeared during the last years. Both photogrammetry and laser scanning are becoming affordable for archaeologists, who often work with limited resources and tight time constraints. This

Omni-directional structure from motion [PDF]

open access: yesProceedings IEEE Workshop on Omnidirectional Vision (Cat. No.PR00704), 2002
In this paper, we describe our work on a robot navigation system using an omnidirectional camera as the primary sensor. An omnidirectional structure from motion algorithm is presented with its uncertainty analyzed. We evaluate the omnidirectional SFM on both synthetic data and on real image sequences. Comparison with the conventional camera is made and

Interpolation in structure from motion [PDF]

open access: yesPerception & Psychophysics, 1992
We investigated surface interpolation in displays of structure from motion (SFM). To do so, we introduced a new method for measuring surface perception in dynamic displays--the SFM probe. An SFM probe is a dot that moves rigidly with the dots on a simulated surface, and whose distance from that surface can be adjusted with a joystick or similar control.

Block Partitioning and Merging for Processing Large-Scale Structure From Motion Problems in Distributed Manner

open access: yesIEEE Access, 2019
The processing time of incremental structure from motion increases exponentially with the number of images. As a result, a huge amount of time is needed for large datasets.

Born-Digital Logistics: Impacts of 3D Recording on Archaeological Workflow, Training, and Interpretation

open access: yesOpen Archaeology, 2021
Digital technologies have been at the heart of fieldwork at the Kaymakçı Archaeological Project (KAP) since its beginning in 2014. All data on this excavation are born-digital, from textual, photographic, and videographic descriptions of contexts and ...

The Potential of Multispectral Imagery and 3D Point Clouds from Unoccupied Aerial Systems (UAS) for Monitoring Forest Structure and the Impacts of Wildfire in Mediterranean-Climate Forests

open access: yesRemote Sensing, 2021
Wildfire shapes vegetation assemblages in Mediterranean ecosystems, such as those in the state of California, United States. Successful restorative management of forests in-line with ecologically beneficial fire regimes relies on a thorough understanding

Analysis of Changes in Forest Structure using Point Clouds from Historical Aerial Photographs

open access: yesRemote Sensing, 2019
Dynamic changes in land use, many of which are related to land abandonment, are taking place in many regions of the world. As a result, forest vegetation appears, which in part is a consequence of planned afforestation programs and in part has the ...
