Coded a bit on our #CCCamp19 #drone project @osm_to and improved the qr-code detection with a 2step approach. I would like to test it with the first images of people doing #cccampmap. So if you have a drone, please go to the #airfield & send me some :). https://github.com/aerospaceresearch/gcp-osm/commit/4059e562a0e2b3ded2a19564746e5dc8cf67c0c9
Here I measured all 3 markers of the big 2x3m QR-Code plane. Not a perfect solution, but very well in the sub-centimeters accuracy.
(Only the marker in the middle (top left of the QR-Code) is our normal reference point. I have measured the other mostly for fun/testing)
Hey #cccamp19 people, show us your aerial photos from the camp airfield! Please tweet, toot, post them here https://events.ccc.de/camp/2019/wiki/Projects:Osm.to#.23CCCampmap_-_Call_for_Coordinated_Mapping_of_CCCamp2019. This is a call for a coordinated #cccampmap event to create a big big orthophoto together!
If you did not already, grab your #drone and fly now :)
@taknil asked: "is the qr code still there? did not find it. Might fly in daytime on day 4." https://twitter.com/taknil/status/1165009637231472643
Answer by quanten: They are still on the official airfield https://events.ccc.de/camp/2019/wiki/Airfield
If you have questions about using them, just ask or come to the #chaoszone and ask for quanten :)" https://twitter.com/quintusquanten/status/1165209233752768513
Morgen ab 12 Uhr findet wieder die #SaturdayMakeSession im #Krautspace statt! Kommt vorbei mit euren Bastelprojekten! @lycian nutzt die Zeit um sein defektes Smartphone zu reparieren. Ob er das wohl schaffen wird? Parallel dazu wird im Hauptraum der Livestream vom #CCCamp19 geschaut und an @osm_to gecodet.
Come, fly and take photos.
The precise coordinates will be measured and published in the next days, but taking photos is already useful. #cccampmap
(Belated) Now in Tent 2 Meitner at #CCCamp19 Lightning Talks
Watch now live: https://streaming.media.ccc.de/camp2019/tent-2
And stay tuned for my talk at 12:45 about @osm_to https://twitter.com/quintusquanten/status/1164478806108905473
Don't miss our #CCCamp19 Lightning Talk: »Automated Ground Control Points for Drones« 2019-08-22, 12:45–12:50, Meitner
We use QR-Codes to create GroundControlPoints for #drone photogrammetry by @quintusquanten. https://events.ccc.de/camp/2019/wiki/Projects:Osm.to #cccampmap https://c3lt.de/camp2019/talk/B9KAHU/
Finally they're there! 15m² of groundcontrol points. Car & parking lot for scale. So we're ready for #CCCamp19. Thx to @quintusquanten @CosmoGecko @DF1LU + other @krautspace to make our #CCCampmap project possible! Want to map the camp, too? Join here https://events.ccc.de/camp/2019/wiki/Projects:Osm.to
Finally, we can do #drone tests! :) Our first qrcode groundcontrol point banner for the #CCCamp19 arrived. All together, let's see if we can do a #CCCampmap w/ @OpenDroneMap & @openstreetmap . More banners'll follow! More infos here https://events.ccc.de/camp/2019/wiki/Projects:Osm.to. Join us by retweet! :)
