Meshroom VS ODM

Take a look at Meshroom from https://alicevision.org/

It's a pretty decent tool, although not sure if videos work well.

I once tried to build a mesh from an aerial video by extracting certain frames and the result was ok-ish

You'll need to get some practice with photogrammetry or other 3D scanning to get the appropriate shapes for each animal, this should be more or less something the right size with adequate straps and padding - https://alicevision.org is a good place to learn about photogrammetry.

Have you tried Alice Vision? https://alicevision.org

Huh. https://github.com/alicevision/meshroom/issues/1650 suggests you can get the camera positions into blender, and then putting pyramids views in, and then get the interested area.

Another alternative for ptgui is https://alicevision.org and it is free

A new version of Meshroom released last month, so I decided to compare the performance and results of the two with the same dataset and mostly the same settings.

If you are starting out, I recommend checking out WebODM. https://opendronemap.org/ the software is NOT super easy to use, but the community is very accepting of newcomers asking questions

https://github.com/OpenDroneMap/ODM

You take a drone, point the camera mostly down (a narrow angle, not straight down), take photos of land, with some overlap, preferably from different angles, load the software, and it creates an ortophoto, 3d model, height map, all georeferenced

If you have a drone there is https://opendronemap.org/

Its not really considered a panorama, I think you might want something like this https://opendronemap.org/

You can run https://opendronemap.org/ on your own computer and get a 3d object, but the technical learning curve is a bit steep.

You could do this through webodm. www.opendronemap.org
