1. An augmented reality (AR)-based route guidance method using a processor, the AR-based route guidance method comprising:
acquiring a driving image captured by an image capturing device of a vehicle, which is running;
acquiring route data to a destination of the vehicle;
recognizing both side lane markings of a lane, in which the vehicle is running from the acquired driving image;
generating first route guidance linear data based on the recognized both side lane markings for a region, in which the both side lane markings are recognized in the driving image;
generating second route guidance linear data using link linear data of the route data for a region, in which the both side lane markings are not recognized in the driving image;
performing error correction of the second route guidance linear data and combining the first route guidance linear data and the error corrected second route guidance linear data to generate combined route guidance linear data; and
displaying a route guidance object in AR using the generated combined route guidance linear data,
wherein the performing error correction of the second route guidance linear data comprises:
calculating a rotation angle of the link linear data based on a difference in angle between a driving direction vector of the vehicle and a route direction vector of the vehicle; and
rotating the link linear data according to the calculated rotation angle.
