Improving Accident Scene Monitoring With Multisource Data Fusion Under Low-Brightness and Occlusion Conditions

IEEE Access
Current road accident survey methodologies often overlook the low-brightness and occlusion conditions, and this study specifically fuses UAV-borne and terrestrial LiDAR data, to facilitate rapid and high-precision accident scene monitoring for these ...

Pipeline Modeling using UAV LiDAR Technology

GEOID
Pipelines play an important role in operations in energy supply companies, whether geothermal, gas, or petroleum. Pipeline damage, such as corrosion, dents, and leaks caused by natural or human factors, must be detected. Problems with pipeline assets will indirectly impact high production prices.

Sea Surface Height Measurements Using UAV Altimeters with Nadir LiDAR or Low-Cost GNSS Reflectometry

Remote Sensing
Although UAV height is precisely determined using GNSS, the vertical distance between the UAV and the sea surface should be subtracted to obtain the sea surface height (SSH).

Airborne lidar observations of water vapour variability and transport [PDF]

, 2012
Water vapour, a minor constituent of the earth’s atmosphere, plays a major role in the radiation budget and the water cycle with important implications for weather and climate. Due to the heterogeneous distribution of its sources, evaporation, and sinks,

An autonomous Unmanned Aerial Vehicle exploration platform with a hierarchical control method for post‐disaster infrastructures

IET Cyber-systems and Robotics
Catastrophic natural disasters like earthquakes can cause infrastructure damage. Emergency response agencies need to assess damage precisely while repeating this process for infrastructures with different shapes and types.
