Dronepictures 3D Scan cant set right Scale

I’m not sure I understood you correctly.

Do you think I should get something to take as an example Exactly 5 meters apart, put it on the floor and scan it and use it to define the distance?
X----5m----X

Yes I have measured the side of the house very accurately, I think you think it is too imprecise to define in RC?

And yes, the GPS measurements are not economically good enough for me to buy something like that. Cost/ benefit is not given.

Thank you alot!
