CityGaussianV2: Efficient and Geometrically Accurate Reconstruction for Large-Scale Scenes

This model, presented in CityGaussianV2: Efficient and Geometrically Accurate Reconstruction for Large-Scale Scenes, offers efficient and high-fidelity 3D reconstruction of large-scale scenes. It addresses challenges in geometric accuracy and scalability by utilizing a decomposed-gradient-based densification and depth regression technique, along with an elongation filter to mitigate Gaussian count explosion. CityGaussianV2 achieves significant improvements in speed, memory usage, and visual quality compared to previous methods.
