Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a block diagram showing an apparatus for generating a map of a navigation system according to an embodiment of the present invention.

As shown in FIG. 1, the apparatus for generating a map of a navigation system according to an exemplary embodiment of the present invention includes a communication module 50 including a navigation module 30, a camera 10, a controller 20, and a drug storage unit 40. )

The navigation module 30 receives a navigation message from a satellite for GPS (Global Positioning System) to determine the current position of the moving object, matches the current position of the moving object with the map data, displays it on the screen, and the destination from the current position of the moving object. The driving route is searched for and the road guide is performed so that the driver can drive the moving object along the searched driving route.

In addition, the navigation module 30 provides the current position information and information on the start point and end point of the important point in the driving route while performing the road guidance.

At this time, the important points include the turn section of the left turn or the right turn, the destination building, the entrance to the parking lot, the number of branch roads and the by-pass road, and the important points can be deleted if necessary.

The camera 10 is installed to illuminate the front of the moving object to photograph the front. In this case, the camera 10 may capture a still image and a video.

The controller 20 receives an important point while the road guide is performed through the navigation module 30, and operates the camera 10 while driving the important point to map the captured image taken based on the location information of the important point. The database is stored in the storage unit 40.

In addition, the control unit 20 is provided to enable the sharing of the stored images when connected to the wired or wireless communication network 60 in conjunction with a smartphone (not shown) or a telematics device (not shown) through the communication module 50. Rather, it is transmitted to the map server 70 so that the map server 70 can process and provide a captured image along with the map data.

2 is a flowchart illustrating a method of generating a direction of a navigation system according to an embodiment of the present invention, and FIG. 3 illustrates a point at which a direction is generated according to a method of generating a direction of a navigation system according to an embodiment of the present invention. It is a figure for following.

Referring to FIG. 2, a method for generating a direction of a navigation system according to an exemplary embodiment of the present invention will first be described. First, while the navigation is performed by the navigation module 30 (S10), the navigation is not completed. The control unit 20 receives the driving information of the important point from the navigation module 30.

Important points may include turning sections, destination buildings, car park ramps, multiple branch roads and by-pass entrances and may be further deleted as needed.

In the present embodiment will be described with respect to the pivot point with respect to the important point.

Therefore, the start time of the rotation section is determined while performing the road guidance (S30).

That is, as shown in FIG. 3, when the start point of the rotation section A is performed on the driving route B for performing the road guidance, the camera receives the photographed image by operating the camera (S40).

The captured image is a moving image or a still image, and in the case of a still image, 5 to 10 still images may be taken while driving an important point.

Afterwards, when the photographed image is provided at the time of inserting the driving direction according to the way in the photographed image so that the photographed image can be used at the time of the road guide, the accurate path guide can be made (S50).
