Abstract

The invention relates to a map data updating method, device and system based on mass production vehicles. The map data updating method comprises the following steps of: acquiring collected data of a mass production vehicle; identifying a to-be-updated object based on the collected data; supplementing and correcting a driving track of the mass production vehicle based on the collected data, and determining the geographic position of the to-be-updated object; and updating a map database based on the to-be-updated object, a geographic position of the to-be-updated object and a corresponding object in the map database. According to the map data updating method, the device and the system, the mass production vehicle is used for collecting data instead of a professional collecting vehicle, and the problem that in the prior art, the map database updating cost is high can be solved; meanwhile, manual participation is not needed in the updating operation process, and the problems that in the prior art, map database updating is low in automation degree and poor in accuracy can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle navigation, in particular to a method, device and system for updating map data based on mass-produced vehicles. Background technique [0002] With the gradual refinement, scale and real-time requirements of spatial geographic information data in many application scenarios, the update frequency of data in map databases (including geographic location information and attributes such as shape, size, and attitude of objects to be updated) is also increasing. come higher. [0003] The existing update method of map database usually needs to dispatch a professional collection vehicle to collect data on the places suspected to need to be updated, and then professional map data operators work on the collected data to complete the update of the map database. The operation process of the operator usually includes: first, the operator processes the collected data and extracts key map elements (object...
