OK, Im having trouble on something that should be a a lot more straight forward. I have two sets of data photographs, one from an UAV, and one from an iphone XR. I have separated them into two different blocks. Here are the steps I perfromed:
1. Added UAV aerial photos in block 1
2. Added iphone XR ground photos in block 2
3. Added camera sensor size info. for iphone XR being 0.39mm (iphone specs say it is 1 / 2.55")
4. Ran AT on UAV aerial photo block
5. Established 4 Tie-Ponts in UAV aerial photo block
6. Ran AT in iphone ground photo block
7. imported tie points from aerial block into ground photo block as control points and tagged 6 photos for each of the 4 GCP's
8. Ran AT on iphone ground photos block using control points
RESULTS - Before I even get to the merge step I have no 3D model view and 0/54 photos were in the main component (whatever that means), and a warning that my focal length differs from the EXIF information
See my 2 screen shots below: Anyone know whats going on here?
