Stitching a pano of a bridge over a lake

[Thomy Kern]

Panos a bridge (drone flies approx. 100 m above the bridge) causes interruptions in the street that leads over the bridge. Probably the wind over the lake.

What can be done about this?

[John Houghton]

Thomy, The misalignments in the street are no doubt due to the parallax effects resulting from the movement of the drone in the wind, as you suspect.  It's a good idea to use control points on the more distant features to get a good alignment there and a tidy horizon as those are likely to be largely free of parallax issues.  Then deal with poor alignment in the less distant features either by manually editing in post processing, or (if you have PTGui Pro), you can try using viewpoint correction to correct for movement of the drone.  See this item in the PTGui FAQ for further information:  https://www.ptgui.com/support.html#5_6 .
