Abstract

The embodiment of the invention provides a method and system for updating a map. The system comprises at least one preset roadside unit, a plurality of mobile devices and a server, wherein the server and the roadside unit are deployed at the same site; the server is an edge computing server and is configured to obtain mobile end updating data, preprocess the preset end environment data to obtain preset end update data, fuse the mobile end update data and the preset end update data, and send the fused update data to the mobile devices to update a mobile end map. According to the method, the transmission data volume can be reduced while the map updating period is guaranteed.

Description

technical field [0001] The invention relates to the field of resource management and application, in particular to a method and system for updating maps of the Internet of Vehicles. Background technique [0002] With the widespread application of autonomous driving technology, vehicles need more accurate maps and a larger observation range to ensure the safety and comfort of passengers. Therefore, the market's demand for high-definition maps (High-Definition Map, HD Map) is becoming more and more urgent. The current method of collecting environmental information based on field-based lidar not only faces high equipment costs, but also seriously restricts the update speed of HD Map. In order to ensure the real-time update of HD Map, the method of crowd sensing can be adopted, that is, the camera, radar and other sensors of ordinary vehicles can be used to realize real-time data collection, and the centralized processing and update of data can be realized through the cloud serv...
