How can the company solve the problem of freshness and breadth of high-precision maps? How much high-precision maps will be installed in 2022? How much revenue will it generate?

NavInfo: Hello, the traditional way of updating maps is to use self-owned collection equipment and update maps on a quarterly basis. However, based on crowdsourced data, it can be updated daily, weekly or monthly according to the needs of car manufacturers. Professional collection vehicles are only used for base map construction and special scene collection, while private cars, commercial vehicles, special vehicles, etc. will become our main crowdsourcing data sources. The current trend of rapid intelligentization of automobiles will provide more high-precision data sources, and the automatic mapping technology based on multi-heterogeneous vehicle sensor data can achieve a higher automation rate, thereby realizing the rapid update of high-precision maps. High-precision maps will increasingly serve as a standard module for L2 and above autonomous driving services, adding value to the autonomous driving solutions provided by the company to car manufacturers and forming differentiated competitiveness relative to other tier1. At present, the delivery of such solutions is very smooth, and please look forward to its contribution to performance.
