In the process of automatic driving, high-precision map plays the role of high-precision positioning, auxiliary environment perception, planning and decision-making. Compared with traditional navigation maps, it is mainly reflected in different users, different uses, different systems, different elements and attributes, and higher map accuracy, richness and freshness. Based on autonomous MMS mobile measurement technology and AI automatic identification technology, Lide high-precision map products have the ability to set high-precision map data collection, production and application in one, with more than 20 years of repeated iterative verification of mature production technology and a complete high-precision map production system.
