Just looking around me now and imagining everything I see having an augmented reality overlay it seems exhausting. I guess the giant blue arrows will help me focus.

pretty much that. They have gone round and taken a video of every street in a certain area, unpacked it, extracted salient points, reconstruct those points to get a 3d map. From that, given any 2d image you should be able to extract a bunch of "salient points" or known points, which from their relationship to each other can tell where the camera is, and what direction its pointing. The two hard parts are 1) collectin…
you can see it here in their demo https://youtu.be/tXwVg2S9wuY?t=60 the "salient points" are called keypoints and their feature vectors are called descriptors https://en.wikipedia.org/wiki/Scale-invariant_feature_transf... you are correct that the challenge is collecting and indexing/retrieving but there have been techniques that do this for a while https://web.eecs.umich.edu/~michjc/papers/p144-park.pdf (they even t…
I have had a look at their API documentation, and what they do is they provide you with an anchor, and that's where you attach your SCNode-s. They use the built-in ORB-SLAM to position your SCNodes, but these are all relative to the main anchor, hence achieving stability and persistence.

> the real thing that i'm puzzled by with blue vision is how they're registering against ARKit descriptors (if they are at all) since apple doesn't expose them in the ARKit api (only the point cloud itself). ARCore used to expose them ( https://stackoverflow.com/a/29012790 ) but i don't think it does anymore. they must be doing the registration because they only support devices that are running ARKit/ARCore (and with…
It'll be so useful to see contextual advertising near all of my favorite shops with the great deals that I love -- all without having to clip coupons! It'll be great when this is paired with facial recognition, so that I can see just the ads that I need for my personal situation at that moment. Maybe they'll even give me a better deal since I'm such a frequent customer!
Two thumbs up!
