Selecting patterns and features for between- and within- crop-row weed mapping using UAV-imagery
(2017-03-30)
This paper approaches the problem of weed mapping for precision agriculture,
using imagery provided by Unmanned Aerial Vehicles (UAVs) from sun
ower
and maize crops. Precision agriculture referred to weed control is ...
The Development of an Open Hardware and Software System Onboard Unmanned Aerial Vehicles to Monitor Concentrated Solar Power Plants
(MDPI, 2017)
Concentrated solar power (CSP) plants are increasingly gaining interest as a source of
renewable energy. These plants face several technical problems and the inspection of components such
as absorber tubes in parabolic ...
Drift Correction of Lightweight Microbolometer Thermal Sensors On-Board Unmanned Aerial Vehicles
(MDPI, 2018)
The development of lightweight sensors compatible with mini unmanned aerial vehicles
(UAVs) has expanded the agronomical applications of remote sensing. Of particular interest in this
paper are thermal sensors based on ...
Positional Quality Assessment of Orthophotos Obtained from Sensors Onboard Multi-Rotor UAV Platforms
(MDPI, 2014)
In this study we explored the positional quality of orthophotos obtained by an
unmanned aerial vehicle (UAV). A multi-rotor UAV was used to obtain images using a
vertically mounted digital camera. The flight was processed ...
Spatial Quality Evaluation of Resampled Unmanned Aerial Vehicle-Imagery for Weed Mapping
(MDPI, 2015)
Unmanned aerial vehicles (UAVs) combined with different spectral range
sensors are an emerging technology for providing early weed maps for optimizing
herbicide applications. Considering that weeds, at very early ...
Carotenoid content estimation in a heterogeneous conifer forest using narrow-band indices and PROSPECT + DART simulations
(Science Direct, 2012)
The present study explored the use of narrow-band indices formulated in the visible spectral region at leaf and canopy levels to estimate carotenoid content. The research area was a pine forest affected by decline processes. ...
Estimating leaf carotenoid content in vineyards using high resolution hyperspectral imagery acquired from an unmanned aerial vehicle (UAV)
(Science Direct, 2013)
Chlorophyll a+b (Ca+b) and carotenoids (Cx+c) are leaf pigments associated with photosynthesis, participation in light harvesting and energy transfer, quenching and photoprotection. This manuscript makes progress on ...
