UPDATING HIGH DEFINITION MAPS BASED ON LANE CLOSURE AND LANE OPENING
This abstract first appeared for US patent application 20240426622 titled 'UPDATING HIGH DEFINITION MAPS BASED ON LANE CLOSURE AND LANE OPENING
Original Abstract Submitted
a computer-implemented method may comprise: receiving sensor data from a sensor of an autonomous vehicle; determining a presence of a lane closure object located on a lane element; determining a change of the lane closure object, selected from the presence of the lane closure object or absence of the lane closure object on the lane element; generating a change candidate based on the change in the lane closure object; obtaining a plurality of the change candidates during a time period or the autonomous vehicle being on a preceding lane element on the route; analyzing the plurality of change candidates for the change being the presence of the lane closure object or the absence of the lane closure object on the lane element; generating a final change candidate based on the change; and providing the final change candidate for updating a high definition map of the route having the lane element.
