LoGeR: Long-Context Geometric Reconstructionwith Hybrid Memory
msuniverse2026: Truly don't understand what is happening in the heads of these researchers. Can't they see how the main use of this is going to be mass surveillance?
haritha-j: I think you've made the erroneous assumption that the researchers care. I work in 3D reconstruction and I've not really seen too many people care about the actual use case, and indeed have had some friends join defence.
KeplerBoy: These seems to be much more robotics / autonomous vehicle focused? I don't quite see the mass surveillance angle you get from this you don't already get from cheap ubiquitous cameras, basic computer vision and networking (aka flock) .
tmilard: Very interesting paper. I can see street-view using it to perfect the 3D analysing of the photo-video they catch with there google-car. What a wonderfull time we are living in ! Specificaly in the Video to 3D reconstruction. Every month, a new brick is put in place.Super
Dead_Lemon: What is the actual objective of this, is it solving an issue or creating a solution to a problem, that is still to be determined? It seems like a lot of energy to replicate a lidar mapping system. It's not like you can expect accurate dimensions from this approximate guess work, excluding the expected hallucinations adding to inaccuracy.
flipbrad: N00b question from me, perhaps, but how easy is it to mount and run Lidar on aerial drones?
petargyurov: It's easy but it's not cheap. Well, price is relative but capturing video is certainly cheaper.Also, I am not sure how heavy LIDAR units are, but remember that the heavier the payload the more the flight time is reduced. Some drones can only have a single payload, so if you also want to capture (high-res) video/imgs you need to fly again.It all depends on the use-case.
voidUpdate: Video cameras are much cheaper and easier to use than LIDAR, like anyone can just pull out their phone, take a video and send it to this algorithm to get a reasonable point cloud of the environment. Sure, if you want an exact model of an environment and you have the time and money, LIDAR would give better results, but this is about doing more with less
_fw: This is like something straight out of Cyberpunk 2077 - the braindances investigation scenes.
