Hybrid Optimization of 3D Gaussian Splatting for Efficient and Realistic Rendering of Urban Scenes
The core message of this paper is to propose a hybrid optimization method, named HO-Gaussian, that combines a grid-based volume with the 3D Gaussian Splatting (3DGS) pipeline to enable efficient and realistic rendering of large-scale urban scenes without relying on SfM or LiDAR point initialization.
