However, the current navigation methods for electronic products are to display two-dimensional planar electronic maps and navigation paths on the display screen. However, electronic maps usually only display basic images, such as road names or major building names, and drivers. The actual front or surrounding scenes are not the same, so the driver must carefully compare the electronic map with the surrounding scene to see the exact location, causing the danger of not being able to identify quickly and intuitively.

In view of the above, in one embodiment, a navigation device is provided for a vehicle, and the navigation device includes a GPS module, a navigation module, a lens group, a processing module, and a display module. The GPS module detects and outputs the instantaneous position of the vehicle. The navigation module is connected to the GPS module, and the navigation module receives the instantaneous location and the destination location of the vehicle and correspondingly generates a navigation map, wherein the navigation map includes a map and a navigation path. The lens group includes a plurality of lenses. The lenses are respectively disposed at different positions around the vehicle to respectively capture a plurality of external images around the vehicle. The processing module is connected to the lens group, and the processing module comprises a three-dimensional image synthesizing unit and a three-dimensional image processing unit, and the three-dimensional image synthesizing unit receives the external images and synthesizes them into a three-dimensional annular projection image, wherein the three-dimensional annular projection image includes the facility image. The three-dimensional image processing unit superimposes the image and the navigation image information on the three-dimensional circular field projection image to form a three-dimensional circular field navigation image, wherein the navigation image information corresponds to the navigation path, and the indicator image is located on the facility image and includes facility information corresponding to the facility image. The processing module outputs a three-dimensional circular field navigation image. The display module is connected to the processing module and the navigation module, and the display module selectively displays the navigation map or the three-dimensional circular field navigation image.

In summary, the driver can switch to display the three-dimensional circular field navigation image during the navigation process, and can view the actual surrounding environment of the vehicle and the facility information of the surrounding facilities, so that the driver can quickly and intuitively identify the location and information of the surrounding facilities. And more accurately know the indication of the navigation information.

In detail, it is assumed that the preset distance is set to 50 meters and 200 meters, respectively. When the driving distance is greater than 200 meters, the display module 50 displays the two-dimensional navigation map 21 when the driving distance is between 50 meters and 200 meters. Between the meters, the processing module 40 outputs the first switching signal to cause the display module 50 to display the three-dimensional navigation map 24. When the driving distance is less than 50 meters, the processing module 40 outputs the second switching signal to display the display module 50. Three-dimensional circular field navigation image I _NA . That is to say, the closer the driving navigation device 1 is to the destination, the finer the navigation image is automatically displayed. In some embodiments, the preset distance may also be set according to user preferences, and the portion is not limited.

In some embodiments, the processing module 40 can also automatically control the display module 50 to switch to display the two-dimensional navigation map 21, the three-dimensional navigation map 24, or the three-dimensional circular field navigation image I _NA according to other preset conditions. For example, the processing module 40 can preset the display of the three-dimensional circular field navigation image I _NA by the two-dimensional navigation map 21 when the driver decelerates the vehicle. Alternatively, when the vehicle module 2 is traveling in a narrow lane, the control module 40 controls the display module 50 to switch and display the three-dimensional annulus navigation image I _NA by the two-dimensional navigation map 21 . In other words, the processing module 40 can automatically display the two-dimensional navigation map 21, the three-dimensional navigation map 24, or the three-dimensional circular field navigation image I _NA according to the driving behavior, the driving environment or other preferences, and the portion is not limited.
