SYSTEMS AND METHODS FOR MAP VERIFICATION
20220042817 · 2022-02-10 ·

Systems and methods are provided for verifying the accuracy of a map. Information regarding objects, such as roadway or roadway-related elements may be encoded into a map to be used for navigation and/or control of a vehicle, such as an autonomous vehicle. In order to verify that the map accurately reflects the roadway or roadway-related elements making up a section of roadway, the vehicle may be driven/ridden along the same section of roadway. A camera feed can be captured of this subsequent traversal of the section of roadway to check if the map includes the requisite roadway or roadway-related elements. The known roadway or roadway-related elements can be occluded from view in the camera feed. Accordingly, if any roadway or roadway-related elements do appear in the camera feed, they can be more easily detected by a verifier, and the processor verification is simplified.

GENERATING SCOUTING OBJECTIVES

Aspects of the disclosure relate to generating scouting objectives in order to update map information used to control a fleet of vehicles in an autonomous driving mode. For instance, a notification from a vehicle of the fleet identifying a feature and a location of the feature may be received. A first bound for a scouting area may be identified based on the location of the feature. A second bound for the scouting area may be identified based on a lane closest to the feature. A scouting objective may be generated for the feature based on the first bound and the second bound.
