This is a Project that I have done for team exact in Olso, I had to photograph the roof and the parking of the building, the whole project took about an hour to complete, had to get permission from Kjeller aerodrome. The flight was done a 70m in a double cross grid to produce 3d model. A Olympus 14-45mm lens was used on on Zenmuse x5s and Dji Inspire 2
