Method and apparatus for associating high-precision map to standard map, mixing navigation method, and mixing navigation apparatus

Abstract

The present invention discloses a method and an apparatus for associating a high-precision map to a standard map. The method comprises: establishing the buffer region of any one high-precision link ina high-precision map, determining the standard link positioned in a standard map and falling into the buffer region, determining the standard link with the heading and the direction respectively corresponding to and consistent with the heading and the direction of the high-precision link in the buffer region, and establishing the association relationship between the high-precision link and the found stand link. With the method, when the user needs to switch the standard map into the high-precision map (or switch the high-precision map into the standard map), the link in the high-precision map(or the link in the standard map) can be found directly according to the correspondence between the identifier of the high-precision link and the identifier of the determined standard link, such thatthe free switching between the standard map and the high-precision map can be effectively achieved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for associating high-precision maps with standard maps, and a hybrid navigation method and device. Background technique [0002] With the continuous progress and development of electronic map navigation technology, more and more electronic map navigation technology is applied to people's daily life. People can use electronic map navigation to reach places they are not familiar with, which greatly facilitates people's Life. [0003] At present, electronic maps used in navigation technology are mainly divided into two types: high-precision maps and standard maps. It provides users with route planning and general navigation functions during the navigation process. [0004] When users want to carry out automatic driving, they need to use high-precision maps for route planning and navigation, and when users just want to perform regular navigation, the...

AI Technical Summary

Problems solved by technology

[0004] When users want to carry out automatic driving, they need to use high-precision maps for route planning and navigation, and when users just want to perform regular navigation, they need to use standard maps for route planning and navigation. The two are independent of each other. To provide users with navigation services, that is to say, it is not possible to switch directly to the standard map for navigation during the navigation process using the high-precision map, nor to directly switch to the high-precision map navigation process during the navigation process using the standard map
