1. An apparatus for recognizing a current position of a vehicle, comprising at least one processor and storage device configured to implement:
- an initial position-receiving unit configured to receive information about an initial position of the vehicle from an external input;
an image data processing unit configured to receive an image signal from an image sensor that is equipped to the vehicle to take a picture of an identifiable object which is stationary near the vehicle, and extract image signal information corresponding to the identifiable object from the image signal;
a database unit including geographic information and information about the identifiable object corresponding to the current position of the vehicle;
an internal network of the vehicle connection unit configured to connect to an internal network of the vehicle, and receive information about a traveling state of the vehicle; and
a position calculation unit configured to calculate the current position of the vehicle based on the information received from the initial position-receiving unit, the image data processing unit, the database unit and the internal network of the vehicle connection unit;
wherein the position calculation unit includesa map-matching section configured to perform map matching on the image signal information about the identifiable object, which is extracted from the image data processing unit, and the information about the identifiable object corresponding to the information about the current position of the vehicle received from the database unit, and correct the information about the current position of the vehicle; and
a calculation section configured to calculate the current position of the vehicle using the corrected information about the current position of the vehicle and the information about the traveling state of the vehicle.

Abstract
An apparatus and method for recognizing a current position of a vehicle are disclosed. The apparatus receive information about an initial position of a vehicle from an external input, and receive an image signal from an image sensor to take a picture of an identifiable object and extract image signal information corresponding to the identifiable object from the image signal, and connect to an internal network of the vehicle of the vehicle and receive information about a traveling state of the vehicle, and calculate the current position of the vehicle based on the information obtained.

10. A method for recognizing a current position of a vehicle, comprising:
-
receiving information about an initial position of the vehicle from an external input; taking a picture with an image sensor equipped to the vehicle of an identifiable object displayed on a road on which the vehicle is traveling, and generating an image signal; receiving geographic information and information about the identifiable object displayed on the road in the geographic information from a database, analyzing data corresponding to the road among the image signal and the information about the identifiable object displayed on the road, extracting the information about the identifiable object, and performing map matching on the image signal information about the identifiable object and the information about the identifiable object corresponding to the current position of the vehicle; correcting the information about the current position of the vehicle using a result obtained from the map matching; connecting to an internal network of the vehicle and collecting information about a traveling state of the vehicle from the internal network of the vehicle; and calculating the current position of the vehicle using the corrected information about the position of the vehicle and the information about the traveling state of the vehicle. - View Dependent Claims (11, 12)
