OpenMVG (open Multiple View Geometry) VS Meshroom

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

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

Photogrametrie https://alicevision.org/

I used Ultra settings as recommended in an issue thread on the meshroom github page. I also tried masking the images using Rembg . I wrote a script that automates the process for me which masks the images and transfers the metadata over to the masked images - here is a link to the script I wrote if anyone finds use for it.

You could start by importing the point cloud model into a software with native support for the file format. Some open source examples are Meshroom (https://alicevision.org) or Meshlab (https://www.meshlab.net). There are other softwares from companies like Autodesk that might be more intuitive but you'd need licenses to use them. Rhino and Blender can handle the file formats but might struggle depending on the size and complexity.

You're probably looking for multiview photogrammetry. Also known as "structure from motion." https://github.com/alicevision/Meshroom is a good free tool for this, but the most popular one is probably AGISoft MetaShape.

huh? https://github.com/alicevision/meshroom

There is also 3DF Zephyr and Meshroom

Are you aware of solutions like Alicevision/Meshroom (MPLv2)?

I would like to understand how Meshroom works under the hood, but couldn't find the source code. There is the github project Meshroom Github, but it only consists of the frontend code and calls the prebuild binaries. Does Meshroom also publish the source code for those binaries or is it proprietary?
