FIG. 5 is a diagram showing an example of displaying a navigation two-screen enlargement diagram according to the present invention; FIG.

Figure 6 is a block diagram showing the configuration of the present invention navigation two screen display control device.

The present invention relates to a two-screen enlarged view that is guided at a position at a left turn, a right turn, an intersection, a bridge, etc. in displaying a guide screen of a navigation. Is a navigational city display that seeks to provide drivers with more realistic and realistic information.

In general, navigation refers to a system for identifying a current user's location using GPS information and guiding a route from the user's location to a destination desired by the user.

The navigation device provides a two-screen enlarged view as shown in FIG. 1 which displays a detailed enlarged view together for convenience of the driver at a place such as a left turn, a right turn, an intersection, a bridge, and the like.

Therefore, the driver will operate the area referring to the detailed screen of the area.

However, this enlarged detailed view is a map information directly produced by the manufacturer, and is inevitably different from the actual road.

Therefore, in the conventional navigation display screen, the driver may cause confusion, and if the driver relies on it, it may cause a safety accident.

In view of the above, the present invention processes the actual photographing image to be displayed for the area providing the detailed view such as the intersection of the navigation by using the aerial photograph data and the satellite photo data, and transmits the processed photo data to the driver. An object of the present invention is to provide a guide screen for navigation that can be displayed on a guide screen.

The present invention provides a navigation system,

A database that stores actual photographic image data in which aerial photographs and satellite photographs have been processed to provide an enlarged view of navigation;

As the vehicle moves along the searched path, the guide point that needs to be enlarged is determined according to the location of the user, such as an intersection, a left turn, a right turn, an intersection bridge, and the like. It characterized in that it comprises a control means for controlling the display of the two-screen enlarged view.

Referring to the embodiment shown in the accompanying drawings, the present invention having such features as shown in Figure 6 as follows.

A GPS receiver 10 for receiving a signal transmitted from a GPS satellite to detect magnetic position coordinates of the vehicle, a geographic information database 20 storing geographic information to be provided to a user with respect to the position coordinates, and a GPS receiver 10 A navigation control unit that provides guidance information according to a user's search path and driving path through a voice or video through the route guide unit 50 according to the geographical information of the geographical information database 20 with respect to the current position of the vehicle recognized from the vehicle. In the navigation system including the 30 and the user key input unit 40,

The geographic information database 20 stores the actual photographed images of aerial photographs and satellite images processed at intersections such as intersections, bridge intersections, and guide points such as left turn and right turn so as to be provided as navigation guide screens. It is configured to include a photo data storage unit 21,

The navigation control unit 30 includes photographed picture display control means for displaying the actual photographed picture by determining the guide position where the magnification is displayed in displaying the path of the vehicle according to the position of the user vehicle. It is characterized in that the configuration.

The present invention having such a configuration,

The aerial photographs and satellite photographs are processed into photographic images so that the aerial photographs and satellite photographs as shown in FIG. 4 can be displayed in the enlarged view shown on the right side of FIG. 3, and the processed photographic image data is converted into a geographic information database (20). The photographed picture data storage unit 21 of FIG.

The aerial photographs or satellite photographs taken at the intersections such as intersections, bridge intersections, guide points, such as left turn and right turn are processed and stored in the photographing data storage unit 21.

At this time, the stored image format uses BMP or JPG.

Referring to the operation of the present invention having such a configuration in detail as follows.

When the user sets a destination and requests a path to the destination, the navigation controller 30 displays a path from the geographic information database 20 to the destination desired by the user on the screen.

Then, when the vehicle starts running, the navigation control unit 30 displays the user's position on the guide screen according to the position of the current vehicle obtained through the GPS receiver 10.

When the driving point reaches an intersection point or a guide point, that is, when a magnification degree is encountered, the navigation control unit 30 displays the processed actual photographed image stored in the photographing data storage unit 21. As shown in FIG. 5.

FIG. 2 is a diagram illustrating a two-screen enlarged view display screen when the conventional two-screen enlarged view display as shown in FIG. 1 is applied to the present invention, and FIG. 5 is a diagram showing a conventional two-screen enlarged view display as shown in FIG. The enlarged two-screen display is a view showing a display screen.

As described above, the present invention can provide the driver with realistic information and guidance by providing an enlarged guide map to the user by using a photograph of a real region such as an aerial photograph or a satellite image.

Claims (1)

In a navigation system, Compose a geographic information database including a photographic data storage unit that stores the actual photographic images processed aerial photographs and satellite photographs to be provided as a navigation guide screen, In displaying the route of the vehicle according to the position of the user vehicle, the navigation comprising a photographing display control means for determining the guide position in which the magnification is displayed to display the actual photographed picture in a two-screen enlarged view 2-screen magnification display.
