Structure from Motion (SFM) como ferramenta de reconstrução tridimensional para edificações históricas

Revista de Gestão e Secretariado (Management and Administrative Professional Review), 2023
Com o advento da tecnologia e das técnicas computacionais é possível obter a representação de edifícios históricos de forma tridimensional e derivar outros produtos que podem ser utilizados em análises, estudos, simulações ou mesmo constituir dados de entrada para outros aspectos, como o BIM (Building Information Modeling).

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

fMRI correlates of subjective reversals in ambiguous structure-from-motion [PDF]

, 2012
We used fMRI to examine the neural correlates of subjective reversals for bistable structure-from-motion. We compared transparent random-dot kinematograms depicting either a cylinder rotating in depth or two flat surfaces translating in opposite ...

Coherence Between Climate and Land Use Polices of the European Union, Brazil, and Indonesia: A Primer to Analyze Potential GHG Leakage

Environmental Policy and Governance, EarlyView.
ABSTRACT Incoherence between national land use policies may weaken climate mitigation efforts by creating conditions under which agricultural and forestry production and GHG emissions are displaced across borders (leakage). Coherence depends on constellations and prioritization of national policy aims in land use (production) and climate (conservation).

Incremental Structure from Motion for Small-Scale Scenes Based on Auxiliary Calibration

Sensors
Scarce feature points are a critical limitation affecting the accuracy and stability of incremental structure from motion (SfM) in small-scale scenes. In this paper, we propose an incremental SfM method for small-scale scenes, combined with an auxiliary ...

Short communication: Challenges and applications of structure-from-motion photogrammetry in a physical model of a braided river [PDF]

Earth Surface Dynamics, 2019
For extending the applications of structure-from-motion (SfM) photogrammetry in river flumes, we present the main challenges and methods used to collect a large dataset (>1000 digital elevation models, DEMs) of high-quality topographic data using ...

Automating Subthalamic Deep Brain Stimulation Programming with Evoked Resonant Neural Activity in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Optimal outcomes from subthalamic nucleus deep brain stimulation (STN‐DBS) for Parkinson's disease (PD) depend on accurate stimulation of an ideal functional target within the dorsolateral STN. Clinical programming is heuristic, and objective methods are needed to improve efficiency and consistency.

Machine Learning Vegetation Filtering of Coastal Cliff and Bluff Point Clouds

Remote Sensing
Coastal cliffs erode in response to short- and long-term environmental changes, but predicting these changes continues to be a challenge. In addition to a chronic lack of data on the cliff face, vegetation presence and growth can bias our erosion ...

THE TRIPLET MEASURED BY AERIAL CAMERA USING LINE SEGMENTS LINE MATCHING-BASED RELATIVE ORIENTATION USING TRIPLET CAMERA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
In urgent observations after disasters, we can mention that the image matching processing is an essential technique to establish more stable and rapid 3D data generation. Particularly, multi-images taken from various viewpoints are useful in the disaster
