The method may include receiving first location information of a vehicle through a location information module, capturing an image through a camera while the vehicle is driven, extracting characteristic points from the captured image and converting the captured image into a 3-D image, obtaining second location information by correcting the first location information based on a moving displacement and orientation direction of the camera installed on the vehicle, extracting an aerial view from the 3-D image based on the moving displacement and orientation direction of the camera, estimating a moving path of the vehicle using locations of traffic lanes included in the aerial view and the second location information, and displaying the captured image and the moving path of the vehicle in augmented reality by combining the captured image and the moving path. According to the present invention, accurate location information can be provided when a vehicle is driven.
