Super landmarks as navigation aids
First Claim
1. A system for autonomously navigating a vehicle along a road segment, the system comprising:
- at least one processor programmed to;
receive from a camera at least one image representative of an environment of the vehicle;
analyze the at least one image to identify at least one recognized landmark, wherein the at least one recognized landmark is part of a group of recognized landmarks, and identification of the at least one recognized landmark is based, at least in part, upon one or more landmark group characteristics associated with the group of recognized landmarks;
update a current location of the vehicle relative to a predetermined road model trajectory associated with the road segment based, at least in part, on a predetermined location of the recognized landmark; and
determine an autonomous steering action for the vehicle based on a direction of the predetermined road model trajectory at the determined current location of the vehicle relative to the predetermined road model trajectory.

Abstract
Systems and methods are provided for autonomously navigating a vehicle along a road segment. In one implementation, a system includes at least one processor programmed to receive from a camera at least one image representative of an environment of the vehicle. The at least one image may be analyzed to identify at least one recognized landmark based upon one or more landmark group characteristics associated with a group of recognized landmarks. The current location of the vehicle relative to a predetermined road model trajectory associated with the road segment may be determined based, at least in part, on a predetermined location of the recognized landmark. An autonomous steering action for the vehicle may be determined based on a direction of the predetermined road model trajectory at the determined current location of the vehicle relative to the predetermined road model trajectory.

16. A tangible and non-transitory computer-readable storage medium that comprises a set of instructions that are executable by at least one processor to cause the at least one processor to perform a method for autonomously navigating a vehicle along a road segment, the method comprising:
-
receiving from a camera at least one image representative of an environment of the vehicle; analyzing the at least one image to identify at least one recognized landmark, wherein the at least one recognized landmark is part of a group of recognized landmarks, and identification of the at least one recognized landmark is based, at least in part, upon one or more landmark group characteristics associated with the group of recognized landmarks; updating a current location of the vehicle relative to a predetermined road model trajectory associated with the road segment based, at least in part, on a predetermined location of the recognized landmark; and determining an autonomous steering action for the vehicle based on a direction of the predetermined road model trajectory at the determined current location of the vehicle relative to the predetermined road model trajectory. - View Dependent Claims (17, 18, 19, 20, 27, 28)
