# Solv3R: 3D Looped Transformer as a Multi-view Solver

Pretrained weights of Solv3R ([paper](https://arxiv.org/abs/2611.02857), [project page](https://ubc-vision.github.io/solv3r/),
[code](https://github.com/ubc-vision/solv3r)).

```python
from solv3r import Solv3R, cameras_from_pose_enc, list_images, load_images

model = Solv3R.from_pretrained()                       # downloads solv3r.safetensors from this repo
images = load_images(list_images("path/to/images"))
ctx = model.encode(images)
z = model.solve(ctx, calls=16)
pred = model.decode(z, ctx)                            # depth, depth_conf, rays, world_points, pose_enc
c2w, K = cameras_from_pose_enc(pred["pose_enc"], (ctx.H, ctx.W))
```

The weights are built on [DVLT](https://github.com/nv-tlabs/dvlt) and are released under the
