{{Glossary|[[Control points]] that define a vertical line in the output [[projection]].}}
The panorama tools [[PTOptimizer|optimizer]] understands various different schemes for
aligning photos using [[control points]]:
Normal points are '''t0''' points, [[horizontal control points]] are '''t1''' points and
vertical control points are '''t2''' points.

The main use of '''vertical control points''' is to change the perspective of the output panorama such that the marked structures are vertical in the output [[projection]]. In a multi image panorama this is only possible if the [[optimization]] of [[Roll]] and [[Pitch]] is allowed for all images and of [[Yaw]] for all but the anchor image.

You set '''vertical control points''' on a vertical structure as far apart from each other as possible.

Please note that real world vertical lines only stay vertical in [[rectilinear]], [[cylindrical]] and [[equirectangular]] projections.

More details in [[Perspective correction]] and [[Panotools internals#Line_control_points|Panotools internals]]
