HD map positioning


The perception system works closely with the HD map to achieve information complementation and precise positioning.
The solution links up the on-board LiDAR and the HD map to achieve lane level positioning. In addition to the safe navigation of self-driving cars, it also takes the OBU (On Board Unit) sensing data to update the HD map, thus the real-time map data updating is achieved with reduced cost.

  • The data transmission interface shares a unified protocol with the communication system.
  • It offers LiDAR point cloud data acquisition, target identifying and tracking algorithms.
  • It also provides environmental change identification, confidence evaluation, and safe transmission of information between different modules.


  • This solution is based on LiDAR sensor which provides high-quality data input for the HD map.
  • It offers professional point cloud data collection ability and sensing data test ability.
