AI Technical Summary

Technical Problem

Traditional road network update methods have long update cycles, high costs, and low completeness and accuracy, failing to meet the requirements of low cost, high precision, and real-time performance.

Method used

By acquiring driving trajectory data and performing trajectory preprocessing, target trajectory data is generated and matched with the initial road network. A pre-trained target model is used to determine drivable road surfaces. Combined with heat map data and spatial matching relationships, road network update intelligence is generated to update the initial road network.

Benefits of technology

It improves the real-time performance and accuracy of road network updates, reduces costs, decreases reliance on manual labor, and enhances the efficiency of road network updates.
