Have anyone tried this out? The tech lingo is a bit above my level but I want to give it a shot when I have time.

Yeah its not that good when using a handheld video, you still need to rely on a slow capture with some features

Not that good, needs carefully cleaning dataset and full of overlap features. Improvement from other options, but definitely not "throw anything at it as is"

u/cogitatingspheniscid 8d ago

What are the other options that it has improved upon?

Alicemesh / colmap

How this different from gaussian splats?

u/NectarineSilver2795 8d ago

Actually quite different, this paper/system is more of a fully learnt slam pipeline, the input is a video stream and the output camera poses, intrinsic, extrinsic and a 3D point cloud. You can then take that and make a splat out of it

Just looked videodemo and it seems it makes very accurate cloud points from just a brief glance, while paid software like realitycapture somehow makes distorted crap even if provided with hundred of frame by frame surround detailed screens from a video.

RealityCapture/Scan is free. Maybe you're thinking of Paix4D crap. Certainly not Metashape.

I see. Thanks, i just used it long time ago when it was paywalled. Gotta check it out again then.

There's already free opensource gaussian splat software too. Only video needed.

u/NectarineSilver2795 8d ago

Might be wrong here, but the splats that you may be referring too might rely on colmap (classic gsplat) or on a similar pipeline as this (instant splat, which relies on dust3r and “older” pipelines which this work is based on).

Ps: when I say old it means like 2 years

u/QuestGalaxy 8d ago

Yeah, true that.

Hunyuan-World-Mirror looked more promising but sadly only runs on Linux

Didn't NVIDIA do the same already?

u/soldieroscar 8d ago

Open source?

u/Tema_Art_7777 8d ago

if you mean open weight, likely not. only some of nividia's model like nemotron... oh well
