I made an inspeccion of the underneath part of a bridge, and wasn't able to georeference the images (GPS interference with the metallic parts).
Anyway, I was triying to make a ortophoto and can't do it because of huge distorsion of the images. The drone was flying close to the bridge (3 meters) and the overlap of the images is enough (between 40-60%). The problem is not the overlapping, seems to be very different orientation and distorsion for being so close to the infraestructure.
Has anyone do something similar? How can I solve it?
Thanks everyone in advance!!
