Hi Nicolas,
I was able to get the images to calibrate using the following Step 1 processing options.
_ Keypoint image scale = Full_
_ Matching Image Pairs = Free flight or terrestrial_
_ Calibration Method = Alternative_
_ Internal parameters optimization = All Prior_
Despite being able to calibrate there is a substantial amount of noise generated by the sky. You can use the carve annotation tool to help reduce the noise before running step 2. Also, I would recommend creating a few MTPs as that also helped improve reconstruction. Below is an image of what I was able to generate. You may be able to improve results by increasing camera height and pointing towards the ground to reduce sky. Multiple passes at different heights would also likely improve reconstruction.
