Original Abstract Submitted
a technique for reconstructing a three-dimensional scene from monocular video adaptively allocates an explicit sparse-dense voxel grid with dense voxel blocks around surfaces in the scene and sparse voxel blocks further from the surfaces. in contrast to conventional systems, the two-level voxel grid can be efficiently queried and sampled. in an embodiment, the scene surface geometry is represented as a signed distance field (sdf). representation of the scene surface geometry can be extended to multi-modal data such as semantic labels and color. because properties stored in the sparse-dense voxel grid structure are differentiable, the scene surface geometry can be optimized via differentiable volume rendering.
