Dear all,
I am pleased to invite you to the next hybrid scientific seminar at the Institute of Geodesy and Geoinformatics (IGG). During the seminar, we will have the opportunity to listen to Dr Grzegorz Jóźków (Institute of Geodesy and Geoinformatics, Wroclaw University of Environmental and Life Sciences, UPWr), who will talk about "Building UAV-borne laser scanning system". The study is a collaborative work carried out by the team consisting of Grzegorz Jóźków, Mateusz Karpina, Wojciech Sowa, and Adrian Kaczmarek.
This time, the main event takes place locally in the IGG library but the presentations will be streamed using Zoom for those who cannot attend the meeting in person.
The seminar starts on Thursday 19th of January at 09:00 AM (CEST).
To join the Zoom meeting please use the link.

Building UAV-borne laser scanning system
Grzegorz Jóźków, Mateusz Karpina, Wojciech Sowa, Adrian Kaczmarek
Electrically powered small (<25 kg) UAVs became in the last decade complementary to manned aircraft platforms used in aerial mapping. Both types of platforms have their advantages and limitations. The obvious advantage of UASs are the costs of equipment and sensors. UASs are usually equipped with off-the-shelf consumer grade inexpensive RGB cameras, however other cameras and laser scanners are getting more attention. The development in the area of navigational (inertial and GNSS) and LiDAR sensors resulted in their miniaturization and price reduction which make them suitable for ULS (UAV-borne Laser Scanning) systems. Obviously the price of such sensors is still much higher than for RGB cameras, causing turnkey ULS systems to be still expensive compared to UASs equipped with mapping cameras. This presentation shows the results of the work performed in IGiG on building our own ULS system. This presentation covers various aspects of the ULS system development, including: mounting of system components, powering, sensor configuration, system calibration, data acquisition and processing resulting in the georeferenced point cloud. In the conclusions we provide our plans for the future work that will result in the improvement of the ULS system performance. Presented work was partially supported by the GATHERS project.
