City-Scale Lane-Level Mapping From Crowdsourced Trajectories and Satellite Imagery

RA-L 2026

Lane-level maps are increasingly preferred over Standard-Definition (SD) and High-Definition (HD) maps, offering a better trade-off among detail richness, coverage breadth, and data freshness. However, constructing city-scale lane-level maps remains time-consuming and labor-intensive. To address the

Enhancing Vectorized Map Perception with Historical Rasterized Maps

ECCV 2024poster

"In autonomous driving, there is growing interest in end-to-end online vectorized map perception in bird’s-eye-view (BEV) space, with an expectation that it could replace traditional high-cost offline high-definition (HD) maps. However, the accuracy and robustness of these methods can be easily comp…

Leveraging Enhanced Queries of Point Sets for Vectorized Map Construction

ECCV 2024poster

"In autonomous driving, the high-definition (HD) map plays a crucial role in localization and planning. Recently, several methods have facilitated end-to-end online map construction in DETR-like frameworks. However, little attention has been paid to the potential capabilities of exploring the query…
