not enough calibrated images

 Flying Phantom 3 over dense area (see screenshot). Initial processing has only 68% of images calibrated. The roads don’t even get lined up.

I changed the calibration method so it’s the accurate geolocation and orientation option, but that didn’t help.

I’m new to this software so any advice would be great. Thanks.

Dense vegetation can be extremely difficult to match. That is probably your biggest issue.

especially if its windy, and thus the trees move between shots.
