I need help with aligning components. I'm running into the same alignment problems again and again:
I'm aligning aerial drone shots (gps georeferenced) with eye-level camera shots (not referenced). Out of 500 shots I get 20+ components, most with 5 or less photos.
I start by picking 5 or so clearly identifiable points in the biggest component on 3-5 photos that have the most matches. Then I go to the next smallest component and try to find the same points in a few images. As I go along, if I can't find 3 points, I add more points...
Eventually, I will run across an image with many identifiable points, but any point mark will report huge amounts of error (>10 px) and I am stuck! Or, I will start getting control point suggestions that are way off the mark. And, if I reconstruct the scene, I will often get misaligned parts floating through my scene...
What is the workflow for dealing with misaligned components? Should I delete the bad components and realign the scene? How do I identify which component is the problem? I can see which photos are misaligned by the bad suggested CPs and by using the 3D control point mode on parts that look bad to see which photos they're coming from, but how do I find out which components a photo is a member of?
Thanks for your help!
