Hierarchy UGP: Hierarchy Unified Gaussian Primitive for Large-Scale Dynamic Scene Reconstruction

3 UESTC Figure 1. Overview of the Reconstruction Improvement of Our Hierarchy UGP on Large-Scale and Large-Motion Scenarios. On the large-scale dynamic scene, the reconstruction quality of Hierarchy UGP significantly outperforms previous methods [4, 40]. For reconstruction of pedestrian with large motions, Hierarchy UGP also demonstrates large improvements.
