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)
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! :)
