Downward facing panoramic?

[HereticDroneworks]

So I've got a client that wants a printed satellite map of his 40 acre property.
But he wants it a CURRENT photograph.
Anyone know how I can use the 2d mapping pictures to stitch them together to have the large image I can bring to the printer?
41x90 inches is the paper size

PTGui or PanoramaStudio 4.1.6 (Pro) are two the best pano stitching software programs, if neither LightRoom nor Photoshop can handle the stitch.

Photo stitching software 360 degree Panorama image software

PTGui is image stitching software for stitching photographs into a seamless 360-degree spherical or gigapixel panoramic image

Create and present 360 degree panoramas | PanoramaStudio Panorama Software

PanoramaStudio merges photos using advanced image stitching to generate seamless panoramas. It creates HDR & gigapixel images and virtual tours for the web.

I use all four programs, depending upon the project and the desired output.

Ok - cool - appreciate the advice.
So I'll be able to use one of these to take a bunch of downward facing images over 40 acres, and make it flat? Not 360?
I gotta git it printed. It's a unique request to be sure, but def a cool idea.
Thanks

I thought this was such a unique idea I tried it in Panovola.

It would not process. Maybe one of the pano software's mentioned above will fare better.

My nadir imagery did have 80/80 overlap which I would guess is too much for Panovola and Panovola did not like the nadir imagery giving an error of "Incorrect Gimbal Yaw".
I tried with datasets from two different drones, one being a Matrice 4E and the other a Mavic 2 Enterprise Advanced.

Hopefully you have a better result than me.

I think I might test this out though and have the Matrice 4E collect images with a much lower overlap and see what happens.

Good luck with your project.

Awesome information - I'm def looking forward to getting in the air and seeing what I can come up with. But it's too cold to even be outside, let alone throwing one of my birds in the air. Northern Minnesota. -27 yesterday morning.
I know it can be done... Otherwise Google maps itself would look weird and distorted...
Just gotta figure out how.

All four of the stitching programs I mentioned are capable of stitching overlapping flat images. Spherical image input and output are only one of their many capabilities for stitching images together, whether shot straight down, shot horizontally, shot straight up, or anywhere in between. Some are better than others, depending upon the source images used for stitching, their degree of overlap, the number of mages, and the size of the images. Gigapanos require lots of computer memory, and have their own unique programs. Let us know how you get on. Sounds like a fun project. Might try one of my own 40 acre spread (aka, my neighborhood)!

Your question intrigued me so I ran some more tests.

When I uploaded all of the mapping images Panvolo failed.

I thought about it and I then removed the images so that I only had images from flight lines running right to left. So in other words I removed the flight lines that ran from left to right.

The result,

It worked great. It actually stitched a challenging area with large portions of grass fields and taken at a low altitude.

Panovolo stitched panorama.





This is what the photogrammetry derived orthomap looks like from the same area. The largest point I noticed is the orthomap's orthogonal view not showing the sides of the building.
If for some reason your client wanted this georeferenced, you could add control points in something like ESRI Arc Pro, but that would distort it a bit.

I attempted a larger one.

This one was a nadir dataset of our beach area.
This one has a couple of stitching areas that I most likely could manually edit to fix.
Same process as above. I removed every other flight line so that the remaining all ran the same direction.

I will try oblique images next.
