They have a "VPS" which extracts keypoints from an image and matches them against a 3d pointcloud. Using trigonometry you can work out the 3d position of the camera by matching the keypoints from the image to the keypoints in the point cloud.

What is different is that they are proposing to make a large ML model to do all of the matching, rather than having a database and some matching algorithm.

Will it work? probably, will it scale? I'm not that hopeful, but then I was wrong about LLMs.
