Vehicle-position-recognition apparatuses, methods, and programs
First Claim
1. A vehicle-position-recognition apparatus, comprising:
- a memory; and
a controller that;
acquires current position information indicating a current position of a vehicle;
acquires road information indicating at least one road based on a connection relationship between plural links;
determines a link where the vehicle travels based on the current position information and the road information;
generates travel-history information indicating a route that the vehicle travels at a point where a link is branched based on the determined link;
acquires an image of an area surrounding the vehicle;
recognizes a recognition target in the acquired image;
stores the generated travel-history information in the memory in association with information indicating the recognition of the recognition target; and
generates learning-priority information indicating a priority of each link branched out at the branch point based on the stored travel-history information and the stored recognition information, the generated learning-priority information being used to determine on which of the links branched out at the branch point that the vehicle is traveling.

Abstract
Vehicle-position-recognition apparatuses, methods, and programs acquire current position information indicating a current position of a vehicle and acquire road information indicating at least one road based on a connection relationship between plural links. The apparatuses, methods, and programs determine a link where the vehicle travels based on the current position information and the road information and generate travel-history information indicating a route that the vehicle travels at a point where a link is branched based on the determined link. The apparatuses, methods, and programs acquire an image of an area surrounding the vehicle, recognize a recognition target in the acquired image, and store the generated travel-history information in the memory in association with information indicating the recognition of the recognition target. The apparatuses, methods, and programs generate learning-priority information indicating a priority of each link branched out at the branch point based on the stored travel-history information and the stored recognition information, the generated learning-priority information usable to determine on which of the links branched out at the branch point that the vehicle is traveling.

15. A vehicle-position-recognition method, comprising:
-
acquiring current position information indicating a current position of a vehicle; acquiring road information indicating at least one road based on a connection relationship between plural links; determining a link where the vehicle travels based on the current position information and the road information; generating travel-history information indicating a route that the vehicle travels at a point where a link is branched based on the determined link; acquiring an image of an area surrounding the vehicle; recognizing a recognition target in the acquired image; storing the generated travel-history information in the memory in association with information indicating the recognition of the recognition target; and generating learning-priority information indicating a priority of each link branched out at the branch point based on the stored travel-history information and the stored recognition information, the generated learning-priority information being used to determine on which of the links branched out at the branch point that the vehicle is traveling. - View Dependent Claims (16, 17, 18, 19)

20. A computer-readable storage medium storing a computer-executable vehicle-position-recognition program, the program comprising:
-
instructions for acquiring current position information indicating a current position of a vehicle; instructions for acquiring road information indicating at least one road based on a connection relationship between plural links; instructions for determining a link where the vehicle travels based on the current position information and the road information; instructions for generating travel-history information indicating a route that the vehicle travels at a point where a link is branched based on the determined link; instructions for acquiring an image of an area surrounding the vehicle; instructions for recognizing a recognition target in the acquired image; instructions for storing the generated travel-history information in the memory in association with information indicating the recognition of the recognition target; and instructions for generating learning-priority information indicating a priority of each link branched out at the branch point based on the stored travel-history information and the stored recognition information, the generated learning-priority information being used to determine on which of the links branched out at the branch point that the vehicle is traveling.
