GS-SDF: LiDAR-Augmented Gaussian Splatting and Neural SDF for Geometrically Consistent Rendering and Reconstruction

1 code implementation13 Mar 2025 Jianheng Liu, Yunfei Wan, Bowen Wang, Chunran Zheng, Jiarong Lin, Fu Zhang

The accurate LiDAR point clouds enable a trained neural signed distance field to offer a manifold geometry field, This motivates us to offer an SDF-based Gaussian initialization for physically grounded primitive placement and a comprehensive geometric regularization for geometrically consistent rendering and reconstruction.

Neural Surface Reconstruction and Rendering for LiDAR-Visual Systems

no code implementations9 Sep 2024 Jianheng Liu, Chunran Zheng, Yunfei Wan, Bowen Wang, Yixi Cai, Fu Zhang

We unify the training of the NDF and NeRF using a spatial-varying scale SDF-to-density transformation for levels of detail for both structure and appearance.
