Pow3R: Empowering Unconstrained 3D Reconstruction with Camera and Scene Priors

Figure 1. Qualitative comparison of raw 3D reconstructions between DUSt3R and Pow3R for the image pair on the left. DUSt3R cannot leverage auxiliary information potentially available at test time, resulting in noisy and low-resolution estimates, whereas Pow3R allows to inject such priors at test time in a versatile manner, enabling new capabilities such as high-resolution processing as a direct by-product.
