OmniVoxel: A Fast and Precise Reconstruction Method of Omnidirectional Neural Radiance Field

no code implementations12 Aug 2022 Qiaoge Li, Itsuki Ueda, Chun Xie, Hidehiko Shishido, Itaru Kitahara

Instead of using a fully implicit representation of rays for radiance field reconstruction, we adopt feature voxels that contain density and color features in tensors.
