I have a project where some cameras are not well aligned and I can solve this by uncalibrating them, adding a few tie points and recalibrating, which places them in a new position, often correct.
Now, this project has a lot of straight lines, which could be modeled with polylines.
Unfortunately, these polylines have only two points (start/end), and we always need to “fully qualify” the points (I mean, mark the point in a few images).
How could we add a lot of valid tiepoints along these polylines without having to mark each one in several images? With such feature, image alignment and calibration would be piece of cake.
