I captured images using an Anafi drone (4k), and I’m having this problem with some images, where the software things the camera was pointing up, or to the side, when it was actually pointing at the ground (you can tell from the images). Flew at 70m above.
It may be a problem with the drone. Is there a way to correct this in Pix4D Mapper? I’ve tried using MTPs - maybe I missed something - but it didn’t correct the problem.
