This video shows RIEGL's complete "turnkey" Airborne laser scanner solution in operation: a DA42 MPP plane equipped with the RIEGL LMS-Q680i Airborne laser scanner. The long-range RIEGL LMS-Q680i airborne laser scanner makes use of a powerful laser source, multiple --time-around (MTA) processing, and digital full waveform analysis.

First experiment with the Velodyne VLP-16 LiDAR 'Puck' mounted on a brushless gimbal on a Devourer X8 heavy-lift multi-rotor UAV. The sensor mount also includes the Advanced Navigation Spatial DUAL GPS/IMU unit and a machine vision camera. This was a first trial of the laser scanner over a small pine stand near South Arm in southern Tasmania, Australia. This project is part of the TerraLuma research group at the University of Tasmania, supported by Supported by the Department of Primary Industries (DPI) New South Wales and the Forest and Wood Products Australia Limited (FWPA).

Dr. Chris Hopkinson discusses airborne laser scanning - what it is, and how it is used. Airborne laser scanning maps ground and near ground surface coordinates at a very high resolution. The presentation covers what types of data can be collected this way, and some applications for use. Dr. Chris Hopkinson is a LiDAR project design and proposal consultant with Otterburn Geographic and now with the University of Lethbridge.

Drone delivers 3D scans models and volumetric data from aerial photos for survey, measurement perfect for mining and excavation, filling analysis and road work planning AIR6 flying robot delivers 3D models and volumetric data from aerial photos Previously, measurements had to be taken on the ground with a laser scanner, but now they can be taken from the sky with camera-mounted drones. This way, measurements are often faster and more precise than those taken on the ground. A drone can easily fly over a large area and measure it perfectly. The resulting 3D models can hardly be distinguished from reality - experts talk about “textured 3D polygonal models.” http://www.airborne-robotics.com/en
3D-Laserscanning der Burg Hochosterwitz in Kärnten / AT. Gleichzeitig Airborne Laserscanning des Gesamtbergs und terrestrisches Laserscanning einzelner Gebäude. Ende November 2010 fand die aufwändige Vermessung und Daten-Erhebung mit modernsten Lasermessgeräten und 3D-Scannern an einem der bedeutendsten Baudenkmale Kärntens, der Burg Hochosterwitz statt. Die Aufnahme erfolgt durch EKG BAUKULTUR, in Kooperation mit der Technischen Universität Wien, unterstützt durch das Land Kärnten und das Bundesdenkmalamt. Ergänzend zur digitalen Aufnahme des Kernbereichs der Hochburg im Jahr 2009 wurden in dieser Aufnahme-Kampagne das Hans-Khevenhüller-Haus, das Pfleghaus sowie die historische Mühle am Fuß des Burgbergs mittels terrestrischer 3D-Laserscan-Technologie aufgenommen. Die Aufnahme des ge...

The VQ-820-G Hydrographic Airborne Laser Scanner is specifically designed to survey seabeds or ground of rivers or lakes integrated into a Complete Platform for Airborne Scanning, simply installed in any type of aircraft platform, e.g. fixed wing or helicopter. More information: www.riegl.com
The RIEGL® LMS-Q780 long-range airborne laser scanner makes use of a powerful laser source, multiple-time-around (MTA) processing, and digital full waveform analysis. This combination allows the operation at varying flight altitudes and is therefore ideally suited for aerial survey of complex terrain. Unique features of this instrument include the automated resolution of range ambiguities, typically occurring at large measurement ranges and high repetition rates. The effect of range ambiguities appearing in airborne laser scanning is known as "multiple-time-around" or "multiple-pulses-in-the-air. RIEGL's new generation of airborne laser scanners overcome this limitation by multiple-time-around (MTA) processing.
A mobile LiDAR scanner mounted on a car or an airborne scanner operated in a helicopter can provide a dense point cloud depicting highways, their surroundings and the road surface very accurately. Using photographs taken at the same time and control points measured with GPS improves the accuracy and helps to compensate the gaps in the GPS signal caused by tall buildings and trees. Laser scanning can be executed without putting people at risk in the middle of busy traffic.
