Systems and methods for lane end recognition

摘要

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a lane ending detection system is provided for a vehicle. One or more processing devices associated with the system receive at least one image via a data interface. The device(s) extract lane ending information from the road sign(s) included in the image data and determine, based on at least one indicator of position of the vehicle, a distance from the vehicle to one or more lane constraints associated with the current lane. The processing device(s) determine, based on the lane ending information and the vehicle position, whether a current lane in which the vehicle is traveling is ending. Further, the system may cause the vehicle to change lanes if the lane in which the vehicle is traveling is ending.

主权项

1. A lane ending detection system for a vehicle, the system comprising:
at least one image capture device configured to acquire at least one image of an area forward of the vehicle, the area including at least one road sign providing information indicative of a lane ending; a data interface; and at least one processing device configured to:
receive the at least one image via the data interface;extract lane ending information from a representation of the at least one road sign included in the at least one image;determine, based on at least one indicator of position of the vehicle, a distance from the vehicle to one or more lane constraints associated with the current lane in which the vehicle is traveling;determine, based on the extracted lane ending information and based on the determined distance from the vehicle to the one or more lane constraints, whether the current lane in which the vehicle is traveling is ending;cause the vehicle to change lanes to a new lane in which the vehicle is not already traveling based on the determination of whether the current lane in which the vehicle is traveling is ending; andupdate, based on the at east one indicator of position of the vehicle, the distance from the vehicle to one or more lane constraints associated with the new lane.
