  • Publication number: 20210172756
    Abstract: An HD map system represents landmarks on a high definition map for autonomous vehicle navigation, including describing spatial location of lanes of a road and semantic information about each lane, and along with traffic signs and landmarks. The system generates lane lines designating lanes of roads based on, for example, mapping of camera image pixels with high probability of being on lane lines into a three-dimensional space, and locating/connecting center lines of the lane lines. The system builds a large connected network of lane elements and their connections as a lane element graph. The system also represents traffic signs based on camera images and detection and ranging sensor depth maps. These landmarks are used in building a high definition map that allows autonomous vehicles to safely navigate through their environments.

  • Publication number: 20200393265
    Abstract: According to an aspect of an embodiment, operations may comprise receiving a set of one or more lane line points each representing a location on a lane line in an HD map, determining an approximate lane line point representing an approximate location on the lane line in the HD map, identifying a region of the HD map surrounding the approximate lane line point, automatically calculating a predicted lane line point in the region representing a predicted location of the lane line in the HD map, displaying, on a user interface, the predicted lane line point on the lane line in the HD map, receiving, from a user through the user interface, confirmation that the predicted lane line point is an actual lane line point, and adding the actual lane line point to the set of one or more lane line points representing locations on the lane line in the HD map.
