Recently, the AR navigation system provides an image of the current road taken by the camera and displays the route to the destination overlaid on the screen, beyond the general navigation device which displays the electronic map on the screen and provides the route. The device is also being introduced.

In recent years, the AR navigation device provides a route on an electronic map as in the related art, and additionally provides an actual road image on one side of the screen to configure the screen so that the driver recognizes the entire route or recognizes the current direction change. Or, a method of superimposing and providing a direction maintenance and a change of a path at a current location on an actual road image by using a connecting line or the like was used.

However, the method of additionally providing an actual road image to one side is very low in utilization due to lack of linkage with a direction indicator.

In addition, the overlapping display method using a connection line invades the area of the actual road image provided on the screen so that the overlapping display is difficult. In many cases, the direction of the is different from the actual road image in a moment, so the reality is inferior and it is difficult to intuitively identify the path direction.

In addition, the conventional AR navigation device provides a real road image, and a display interface that allows the driver to easily grasp the entire route while driving on the same screen is not provided directly on the screen of the real road image, thereby greatly reducing visibility. The driver had difficulty in intuitively understanding the entire route.

Accordingly, there is a need for an AR navigation apparatus capable of clearly recognizing a momentary change of direction without impairing the realism in a screen providing a complicated real road image.

In addition, there is a need for an AR navigation device that provides an actual road image while at least invading the entire area so that a driver can easily recognize the direction of the entire path while driving.
