High-precision maps not only have high coordinate accuracy but also contain abundant road traffic information elements, and can provide prior knowledge and redundant positioning guarantees. The high-precision map acquisition system can also be called "Mobile Mapping System" or MMS for short, which represents the development mainstream of the field of road electronic map measurement and production in the future. It is a mobile carrier equipped with advanced sensors and equipment such as inertial navigation system, GNSS, laser radar, panoramic camera, etc., to quickly collect urban real-life images and spatial location data and attribute data of various urban facilities to form a city's three-dimensional data platform of urban total elements, visualization, and measurement.
