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
