OpenSfM VS Blender-Addon-Photogrammetry-Importer

OpenSfM (JSON)

You're kidding right? There are lots of coders on github with open-sauce Python. The basic algorithm being used now is Structure-from-Motion (SfM). Photogrammetry started with projecting a red stripe light on the object, taking the photo, and manually stitching together common points. That uses edge detection, another algorithm. Everybody knows the Z-depth calculation algorithm, and that is starting to be done with AI. Sony is using some scrolling parallax algorithm with their photogrammetry software. It looks like Reality Capture can calculate the camera positions and angles first, then use photon tracing rather than ray tracing to determine the point cloud.

OpenSfM is written in Python and JS and pretty easy to understand.

However, traditional methods (Like these photogrammetry addons: https://github.com/SBCV/Blender-Addon-Photogrammetry-Importer, https://www.blendermarket.com/products/pcv ) haven’t worked, due to the reference images these being varying quality screenshots, rather than actual uniform photos. I had the idea of somehow using photogrammetry software to align these images (Creating a point cloud), and importing the aligned files into Blender, but that hasn’t been successful.
