AIRBORNE TO UAS LIDAR: AN ANALYSIS OF UAS LIDAR GROUND CONTROL TARGETS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Creating accurate models of the Earth’s surface is an essential step when analysing geomorphological changes through time. Alongside photogrammetry, airborne lidar is an established method for measuring and modelling the Earth’s surface.

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

BMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

CHANGE DETECTION BETWEEN DIGITAL SURFACE MODELS FROM AIRBORNE LASER SCANNING AND DENSE IMAGE MATCHING USING CONVOLUTIONAL NEURAL NETWORKS [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Airborne photogrammetry and airborne laser scanning are two commonly used technologies used for topographical data acquisition at the city level. Change detection between airborne laser scanning data and photogrammetric data is challenging since the two ...

Improved Target Laser Capture Technology for Hexagonal Honeycomb Scanning

Photonics, 2023
In laser tracking systems, capturing moving targets is a prerequisite to guaranteeing a tracking system’s performance. Previous studies have confirmed that the capture probability of hexagonal spiral scanning is higher than that for other scanning ...

Canopy structural modeling using object-oriented image classification and laser scanning [PDF]

, 2008
A terrestrial laser scanning (TLS) experiment was carried out in the EAGLE 2006 campaign to characterize and model the canopy structure of the Speulderbos forest. Semi-variogram analysis was used to describe spatial variability of the surface.

Wearable photovoltaic textiles: From device technologies to long‐term reliability

InfoScience, EarlyView.
Wearable photovoltaic textiles are highlighted as reliable energy sources that combine solar cell efficiency with hierarchical textile‐specific mechanical and environmental durability. Structural and encapsulation strategies, including planarization, neutral‐axis engineering, and advanced barrier designs, enable waterproofing, washability, UV shielding,

Near field enhancements from angled surface defects : a comparison of scanning laser source and scanning laser detection techniques [PDF]

, 2011
Enhancement of the Rayleigh wave signal amplitude at a surface defect, due to interference of incident, reflected and mode converted waves, has been reported by several authors, and it has been suggested that this could be used as a fingerprint of the ...
