DiffVL: Diffusion-Based Visual Localization on 2D Maps Via BEV-Conditioned GPS Denoising

ICRA 2026poster

Accurate visual localization is crucial for autonomous driving, yet existing methods face a fundamental dilemma: While high-definition (HD) maps provide high-precision localization references, their costly construction and maintenance hinder scalability, which drives research toward standard-definit…

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

ICCV 2025poster

Recent advances in differentiable rendering have significantly improved dynamic street scene reconstruction. However, the complexity of large-scale scenarios and dynamic elements, such as vehicles and pedestrians, remains a substantial challenge. Existing methods often struggle to scale to large sce…
