This is the link to the pix4d files (p4d, log and report pdf) https://we.tl/yB45ynXJH3 . Unfortunatelly pix4d fails to upload it to the cloud - we reported that already to support.
In essence we import the R_jpg pictures, what is split into rgb (jpg) and thermal (tif) by pix4d, we then disable the jpgs and only enable the “grayscale” tifs. Furthermore we only allow pictures taken above 400 m, so pictures near the ground are disabled.
We then select the thermal template and select Tau2 13mm, where we manually reset distortion parameters to be 0.
I had some success with applying alternative processing vs. standard, but I have no conclusive opinion about the step mentioned by Ina (“After changing the pixel size run step 1 and then if the difference between optimized and initial internal camera parameters is high then opt for All Prior.”).
Any of your insight would be greatly appreciated!
If you need more raw data I would be happy to share - we have a 37 km x 400 m corridor captured!
