OpenMVG (open Multiple View Geometry) VS ODM

Try to find a community that will know more about openMVG, like the discussion tab on their github.

OpenMVG (JSON, NVM, PLY)

I find openMVG very decent, FTXUI might be a good one and nlohmann's json library is also pretty nice. I don't really know of any project that strictly adheres to the core guidelines, except maybe for some of Jason Turner's (sample) projects.

I am looking for some pointers to papers/open-source software that can do fast and accurate depth estimation from multi-view videos. I am aware of colmap and OpenMVG software but was curious to know if there are others out there that outperform these. I am also interested in any state-of-the-art for depth estimation using unsupervised or self-supervised neural networks.

OpenMVG is super cool, and the project lead Pierre is very generous with his time.

Meshroom is just a Python wrapper for VSfM. OpenMVS seems like the package most customizers are starting to use. https://github.com/openMVG/openMVG

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
