FSU Jena wins the SPSG Park3D Project!

The FSU Jenacopter Labs team wins the Park3D project proposal with SPSG (Stiftung Preußische Schlösser und Gärten). In 2025 and 2026 we will in detail analyze the vitality of the vegetation in the historical park regions Sanssouci and Babelsberg / Potsdam with various copter-based sensors: The P1 (a 35mm full frame 45 Megapixel RGB camera) will be used for detailed...

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...

Apple M1Max 24C and 32C and Agisoft Metashape – a Performance Surprise

Update: 5.4.2022: added the 32C performance of the MBP21 16Inch with 64GB RAM Or … the resurrection of the MacBook Pro as we knew it years ago … . I have been writing about the MacBook Pro before but I have in recent years been wondering why Apple did not manage to develop a competitive laptop with performance, battery life...

Reflectance Calibration with Phantom 4M Multispectral data (Updated 14-05-2021)

Last Update: 14.5.2021 There was some confusion in the past on how to process the Phantom 4M Multispectral data to “reflectance” level. Here a short summary for Agisoft Metashape 1.7.2 with a 50% reflectance panel from Micasense (update: now its from SphereOptics). In general: 1. the P4M sun illu. sensor works for normalizing the within flight campaign variations while 2....

SARS-CoV-2 Cartograms

Update 4.4.2020 Cartogram reprojection using county based shapes and recent data from RKI. These maps are quantile classified – not equal interval classified. This clearly changes somehow the color distribution since the local maxima are not visible anymore. Overall this visualization is graphically very appealing – however it needs more attention for the legend to understand the distribution of values....

Cluster & Batch Processing in Agisoft Metashape

20 days! – better/faster hardware anyone? Processing large quantities of image files from UAV flight campaigns in Agisoft is sometimes very time consuming and usually should be done in a cluster environment with distributed nodes doing the heavy pixel lifting. Sometimes even a cluster setup can be limiting when the subprocess needs more RAM memory than available on a single...

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...

“DJI GS Pro” – Ground Station Testing

Some tests using the DJI GS Pro (Ground Station) software for automatic flight programming with the Phantom 4 Pro. New flight campaign at the Kuckenburg spot (Sachsen-Anhalt) finished with two different flight altitudes using DJI GS Pro – mapping the open archaeological excavation site of medieval church now in September 2017. This worked flawless – the only problem: you kind...
