Problem addressed

Leveraging infrastructure, VI-Map seamlessly integrates roadside sensor perception with vehicle perception to automatically construct HD maps in real time, significantly reducing mapping costs while ensuring timely and accurate map updates.

Innovation
  • Utilizing density, direction, height, and intensity features extracted from LiDAR point clouds, the infrastructure can efficiently construct a local HD map.
  • Using vehicle trajectories and lane instance segmentation, VI-Map constructs the road's driving topology within the map.
  • Propose a three-stage mapping algorithm to fuse two vectorized HD maps from vastly different perspectives.
Key impact
  • This technology can greatly improve the accuracy and scope of autonomous driving mapping and improve the efficiency and safety of autonomous driving.
  • This technology can effectively overcome complex environmental disturbances, such as severe weather and blocked areas, broaden the feasible range of autonomous driving, and improve its adaptability and reliability in various scenarios.
