Apparatus and method for recognizing location of vehicle
First Claim
1. An apparatus for recognizing a location of a vehicle, comprising:
- a landmark recognition unit for receiving information about images of landmarks, indicated around a road in a direction in which the vehicle is traveling, from an image sensor, and recognizing a reference landmark closest to the vehicle based on the image information;
a distance recognition unit for collecting values of distances to the reference landmark from a range sensor; and
a vehicle location calculation unit for calculating a final location of the vehicle based on basic information about the reference landmark and the distance values;
wherein the landmark recognition unit searches a landmark information table for information about a location of the reference landmark, and calculates range angles with respect to the reference landmark based on a location of the image sensor.
