RE: Quantitative building thermography
What you are trying to do is extremely difficult even with training. It is not just a matter of using standardised values for emissiivity and reflected temp. You need to understand how and why these give you errors, this takes quite a bit of training and experience.

What you are experiencing is that thermography is not as easy as you thought, and this if anything is highlighting the need for training.

My advice is not to try to measure U values from a drone based camera at a distance of 60m without any training. Stick to qualitative thermography, if you need to measure accurate U values, then you will need additional instrumentation, and strong knowledge of building physics, it will not be possible to do it accurately just with a drone.
