📢📢GenRecon: Bridging Generative Priors for Multi-View 3D Scene Reconstruction📢📢 Reconstructing high-fidelity 3D scenes from sparse RGB input is hard. It needs a strong 3D prior! We reformulate multi-view scene reconstruction as conditional 3D generation over overlapping spatial chunks, lifting posed image features into a generative shape prior via 3D... show more

Here is another result on a short sequence of sparse RGB images. GenRecon operates on a chunk-by-chunk basis and the reconstruction accurately matches the constraints from the input images. At the same time, we obtain clean, high-quality 3D geometries with PBR materials.

@angelaqdai I am surprised to see that multi view reconstruction was achievable with just applying LoRA to Trellis; since the training space seems drastically different. Excited to try this out! Great work team!

@angelaqdai Thanks, yeah it works quite well although it needed a bit of training. Overall, it seems to retain the clean shape prior quite well.

Amazing stuff! Love how 3D generation is getting closer and closer to the real data and is filling all the missing data.

wow, that's an impressive amount of detail for that quick swipe

Is there any concept of generative 3DGS where using AI models we could generate fake gaussians for the angles that were not part of the original camera movement?

Does this produce metric-accurate reconstructions, or at least preserve relative scale accurately enough to rescale later? If yes, this could be very useful for Real Estate Digital Twin applications.
