DJIs new UAV Lidar System – the L3

DJI has recently announced the release of its new UAV LiDAR system — the DJI Zenmuse L3. For those engaged in UAV-based LiDAR research and applications, this long-anticipated successor to the L2 represents a significant technological advancement. The cost of professional-grade airborne LiDAR systems with high-accuracy capabilities has remained relatively stable over the past years. For example, some of the...

FSU Jena wins the SPSG Park3D Project! Updated

First L2 LiDAR data capture over Park Sanssouci – (2025-07-20)  Priority was on detailed and dense vegetation point clouds. The L2 was used in 120m AGL with 240khz capture rate and 5-returns activated and 70% track overlap at 8m/s speed.  We generated a 2.4billion point cloud description. The following animation is from a downsampled version of only 500 mio points....

3D point cloud of the 1000 years old Ivenacker Oack Trees

Its always a challenge to work on vegetation point cloud renderings with multi view image matching concepts. In complex 3-dimensional environments and for horizontal image capturing – using a drone is often just not possible. Here horizontal imaging can be an affordable alternative to TLS (Terrestrial Lidar Scanning) systems. Drawback of most OTS consumer electronics camera systems is the missing...

The Hainich Flight Campaign

At the end of August 2018 a consortium was initiated by Dr. C. Thiel (DLR) to start a flight campaign within the Hainich national parc area in Thuringia (DLR Jena: Dr. C. Thiel, FSU Jena: Dr. S. Hese, University Göttingen (LS für Bioklimatologie, Prof. Dr. A. Knohl / Dipl.-Ing F. Tiedemann), national parc Hainich: Manfred Grossmann & Andreas Henkel).  The region is...

Punktwolkenmodelle für die Archäologie

Die unterschiedlichen Datensätze der Befliegungen für die Grabungen auf dem Alten Gleisberg und bei Kuckenburg in 2017 sind nun vollständig an das Seminar für Ur- und Frühgeschichtliche Archäologie übergeben worden. Die abgeleiteten Datenlayer umfassen jeweils Punktwolkenmodelle im LAS Format, DSM (Digitales Oberflächenmodell ohne Normalisierung) und jeweils das Orthomosaik mit Georeferenzierung von der Befliegung. Alle Daten wurden nach UTM32 WGS84 georeferenziert. Insgesamt wurden Daten...
