RTMap: Real-Time Recursive Mapping with Change Detection and Localization

Yuheng Du, Sheng Yang, Lingxuan Wang, Zhenghua Hou, Chengying Cai, Zhitao Tan +3

ICCV 2025poster

While recent online HD mapping methods relieve burdened offline pipelines and solve map freshness, they remain limited by perceptual inaccuracies, occlusion in dense traffic, and an inability to fuse multi-agent observations. We propose RTMap to enhance these single-traversal methods by persistently…

EgoVM: Achieving Precise Ego-Localization using Lightweight Vectorized Maps

Yuzhe He, Shuang Liang, Xiaofei Rui, Chengying Cai, Guowei Wan

IROS 2024poster

Accurate and reliable ego-localization is critical for autonomous driving. In this paper, we present EgoVM, an end-to-end localization network that achieves comparable localization accuracy to prior state-of-the-art methods, but uses lightweight vectorized maps instead of heavy point-based maps. To…
