- Abstract: We present a novel method for reconstructing a 3D implicit surface from a
large-scale, sparse, and noisy point cloud. Our approach builds upon the
recently introduced Neural Kernel Fields (NKF) representation. It enjoys
similar generalization capabilities to NKF, while simultaneously addressing its
main limitations: (a) We can scale to large scenes through compactly supported
kernel functions, which enable the use of memory-efficient sparse linear
solvers. (b) We are robust to noise, through a gradient fitting solve. (c) We
minimize training requirements, enabling us to learn from any dataset of dense
oriented points, and even mix training data consisting of objects and scenes at
different scales. Our method is capable of reconstructing millions of points in
a few seconds, and handling very large scenes in an out-of-core fashion. We
achieve state-of-the-art results on reconstruction benchmarks consisting of
single objects, indoor scenes, and outdoor scenes.

We introduce a new method that directly leverages scene geometry from the training database.
First, we learn to synthesize an initial estimate for a 3D scene, constructed by retrieving a top-k set of volumetric chunks from the scene database.
These candidates are then refined to a final scene generation with an attention-based refinement that can effectively select the most consistent set of geometry from the candidates.
We demonstrate our neural scene reconstruction with a database for the tasks of 3D super resolution and surface reconstruction from sparse point clouds.
