Feature information collecting apparatuses, methods, and programs
First Claim
1. A feature information collecting apparatus, comprising:
- a memory; and
a controller that;
acquires vehicle position information that represents a current position of a vehicle;
acquires image information of a vicinity of the vehicle;
carries out image recognition processing of a target feature that is included in the image information to determine a recognition position of the target feature;
stores recognition position information in the memory that is based on the acquired vehicle position information and that represents the determined recognition position of the target feature; and
determines an estimated position of the target feature based on set of a plurality of stored recognition position information for the target feature, the plurality of stored recognition position information for the target feature being stored due to the target feature being subject to image recognition processing a plurality of times.

Abstract
Apparatuses, methods, and programs acquire vehicle position information that represents a current position of a vehicle, acquire image information of a vicinity of the vehicle, and carry out image recognition processing of a target feature that is included in the image information to determine a position of the target feature. The apparatuses, methods, and programs store recognition position information that is based on the acquired vehicle position information and that represents the determined recognition position of the target feature. The apparatuses, methods, and programs determine an estimated position of the target feature based on a set of a plurality of stored recognition position information for the target feature, the plurality of stored recognition position information for the target feature being stored due to the target feature being subject to image recognition processing a plurality of times.
