Hi Frank,

Often these problems are caused by differences in elevation of the drone
while the panorama was taken.

Could you make a set of images and your project file available for download?

Kind regards,

Hi Frank,

The stitching errors indeed seem to result from a change in elevation
during the shoot. The giveaway is the fact that the horizon mismatch
happens mostly between the first and last image of the series (where the
altitude difference would be maximal).

I managed to get a nice result though, as follows:

- load all images
- run Align Images
- PTGui will complain about one image without control points (the one
facing down on the black water). Just ignore, it's already roughly
positioned.
- Switch to Advanced mode
- go to the Optimizer tab
- switch the Optimizer to Advanced mode
- Set the 'viewpoint' column to 'Optimize' for all images, except for
image 1. For image 1 Viewpoint should be set to Reset.
- Run the Optimizer. It reported good alignment
- Do Control Points - Generate Control Points. This will generate extra
control points fitting the (now) viewpoint optimized images
- Do Control Points - Remove Worst Control Points

I also leveled the horizon by placing 3 Horizontal Line control points
(see Video Tutorial #8). And I've masked out the bottom part of the
images above the horizon, so they will only be used for the sky part.

See my project file (attached). Hope this helps.

Kind regards,

This tutorial from 10 years ago should help: http://www.johnhpanos.com/horizons.htm . The screenshots may look somewhat different to the current version of PTGui, but you should be able to follow it.
 

and you send me the panorama .pts file i have no idea what to do with it.

The .pts project file was produced with File->Save Project.  You can recreate that state of the project by copying this project file into the folder that  holds your images and simply open it with PTGui  using File->Open Project.

You're not the first to struggle with horizon misalignments in drone
panoramas. So I've added this as a note to the support page, with some
extra information.

See 5.6:

I still struggle . i wish i could understand this program more .  you said :I also leveled the horizon by placing 3 Horizontal Line control points
(see Video Tutorial #8). And I've masked out the bottom part of the
images above the horizon, so they will only be used for the sky part. 

I saw indeed you masking the bottom part of some images . how you know wich images you need to mask out. also one image is vertical nr 18 whys is that. ? and how you did this.     do you need Always masking out ? stil a lot of questions but i cant go further with my drone panos . stil paralax errors but i didnt masking out .also in the tutorial there is no word on masking out also .

is there a way you can make e video tutorial on this incl the masking oiut proces en when you do this on what image?

I took all the sky images and masked out the horizon and below. Perhaps
this was not necessary (I did not check) but I figured since there will
be misalignments due to parallax, and the horizon is very critical, it's
best to have only one row of images contribute to the horizon area.

It can be done quickly: just draw the mask in one of the horizon images,
and use copy (Ctrl+C) and Paste (Ctrl+V) in the mask tab.

> also one image is vertical nr 18 whys

I didn't rotate the image, but PTGui displays it rotated. Actually this
is a bug, PTGui attempts to rotate all thumbnails in the main window
such that they have the same orientation as the image in the panorama,
but it can get it wrong if viewpoint correction is used. Just ignore it,
or rotate the image manually by using the arrow buttons at the bottom of
the Mask tab.

No, see above.

It may not be necessary to mask. But masking may help to resolve
misalignments.

Hello,

After making panoramas with two different drones (one that cannot shoot straight up, and one that can) I've concluded that it's usually best to autofill the apex in Photoshop. Also, I've found that once you have an aerial pano shot in relatively still air that stitches successfully, using that one as a template may be a very good way to begin. 

I've created a website for the drone-enabled panoramas, all stitched with PTGui:

Hi Joost,

Again thank you for your time and your help.  

i understand more now.

Dji drones are also notorios for making images with no straight horizon and afcours that is also a problem for the stitcher i am goig to dive in again . thank you Joost
