If you are interested in photogrammetry, Meshroom is a great option. However, you need CUDA for it, so it won't work on computers without an NVIDIA graphics card. I found a way around this using Google's free Colaboratory (colab.research.google.com), which gives you access to cloud computers. This has the advantage of being able to run on any computer, and it won't slow down your computer while Meshroom is running! I hope you find this tutorial helpful.
