Nice results, thermal cameras aren't easy to work with, especially in terms of artistic result. I've seen problems with stitching resulting with artifacts in panoramas. As I understood (I'm not thermal cameras expert) it's due too the fact that sensor warms up -> thermal camera calibration doesn't correct the result enough -> stitching needs corrections.

To put it one dimension higher, in Pix4D we work on 3d models based on the thermal images: https://www.youtube.com/watch?v=x-jp9a1bpVU Example: https://sketchfab.com/3d-models/thermal-model-of-pix4d-headq...
