Abstract
This invention discloses a navigation method, apparatus, and electronic device based on lane-level local maps. The method includes: activating a local map navigation mode in response to receiving a local map navigation activation signal; acquiring high-precision map data and perception data; constructing a lane-level local road map based on the high-precision map data and perception data; rendering lane-level navigation guide lines in the lane-level local road map based on the high-precision map data, navigation route information, and the vehicle's current lane information; and navigating the vehicle based on the lane-level local road map and the lane-level navigation guide lines. This invention solves the technical problems of high cost in acquiring and updating high-precision maps, and the inability of high-precision maps to provide lane-level guidance in related technologies.
