Embodiment Construction

[0031] In the prior art, the update and distribution of high-precision map data mainly depends on the cloud to compile independent map data package files, and it takes a certain amount of time for data transmission and data package compilation, which is likely to cause updates caused by network transmission. The failure problem makes it impossible to meet the real-time requirements.

[0032] Therefore, the embodiment of this specification provides a high-precision map data incremental distribution method, device, and electronic equipment through serialized map update data, which saves the link of compiling map packages, simplifies the map update process, and compresses the time-consuming map update. . By using the incremental map data update strategy, the updated data transmitted is small, reducing the pressure on map data transmission, and improving the response time of server and terminal data transmission. By using the small-batch data update requirement, for the small-bat...

Abstract

The invention relates to the technical field of high-precision maps, in particular to a high-precision map data incremental distribution method and device and electronic equipment. The invention discloses a high-precision map data incremental distribution method, which is applied to a server side and comprises the following steps of: acquiring update data, loading the update data into a server side map, updating the server side map and generating an update version number corresponding to the update data; and sending an updating command to the terminal, obtaining updating request information of the terminal and the version number of the current map, performing differential query on the map data corresponding to the current version number and the map data corresponding to the updated version number to obtain incremental data, and serializing the incremental data and sending the incremental data to the terminal.

Description

technical field [0001] The present application relates to the technical field of high-precision maps, and in particular to a method, device and electronic equipment for incrementally distributing high-precision map data. Background technique [0002] With the development of autonomous driving technology and intelligent network technology, high-precision maps play an important role in the perception and calculation of vehicle positioning. Compared with traditional navigation electronic maps, high-precision maps have higher data accuracy and can be more accurate and comprehensive. Express road characteristics while requiring higher real-time performance. The update and maintenance of the high-precision map data, on the one hand, edit and update the data according to the changes in the road conditions on the ground; It needs to be distributed to each terminal device in time. [0003] At present, the update and distribution of high-precision map data mainly adopts the update m...
