I am collecting repeat orthoimagery, and pilots sometimes are not able to follow tight flight lines, but I always have good (>60%) along-path overlap - where the sidelap decreases to <30% or where I am in heavily forested areas, sometimes the alignment "blows up" - even though images are taken on a linear flight path, I can't constrain the solutions.
tried to post an image, but "UPLOAD FOLDER IS FULL" error w 99KB image
It would be nice if I could constrain the vertical angle of images to within X° of the others, and even better if I could constrain the distance from image X to image Y for subsets as I add them.
The other thing that happens when the image alignment blows up is that the ground plane generally is off by 90° or 180°. If I could specify that this is an orthophoto flight and have the ground plane be normal to the alignment of the majority of the images, that would be ideal.
I know forests are hard for automagical point-finding, and most of the time this issue never comes up, but it sure would be neat to constrain this.
Also I know if I had GPS locations for camera data that would be better, but I can't do that at the moment. Am using GCPs for orthoimage production.
