In all examples shown and discussed herein, any specific values should be construed as exemplary only, and not as limitations. Therefore, other instances of the exemplary embodiment may have different values.

It should be noted that like numerals and letters denote like items in the following figures, therefore, once an item is defined in one figure, it does not require further discussion in subsequent figures.

Fig. 1 is a schematic flowchart of an embodiment of a method for displaying a direction board in navigation according to the present invention.

According to shown in Figure 1, the inventive method comprises the steps:

Step S101, receiving a navigation instruction.

The navigation instruction is usually input by the user via an electronic device, and the navigation instruction may be a set starting point and destination.

The device for the user to input navigation instructions may be a keyboard device, a handwriting device, a voice input device, and the like.

Step S102, loading a two-dimensional navigation map, and providing a two-dimensional navigation route according to the navigation instruction.

The two-dimensional navigation map is loaded based on a two-dimensional navigation map database.

The two-dimensional navigation map database is used to store high-precision two-dimensional navigation data (X, Y).

Corresponding to the navigation instruction for setting the start point and the end point, the two-dimensional navigation path is a path that enables the object to be navigated to reach the set end point from the set start point.

The two-dimensional navigation route can be displayed on a two-dimensional navigation map.

Step S103, determine the current position of the object to be navigated, and determine the current road section where the object to be navigated is located according to the current position.

In this step, the current position of the navigated object can be determined according to the data provided by the GPS positioning device configured on the electronic device, and then its actual position on the urban road can be determined.

Furthermore, the current driving lane of the object to be navigated can also be determined according to the data provided by the GPS positioning device, so as to prompt the user to change lanes according to the two-dimensional navigation route.

Step S104, judging whether there is an indicator board in front of the current road section on the current road section, if yes, execute step S105, if not, wait to enter the next road section, and start the next judgment.

The indication board can be made according to the road signs surveyed on the spot, which has the same indication information as the corresponding road signs, and the indication information can be displayed according to a unified standard (for example, a uniform color tone).

Figure 3 shows a schematic diagram of an indicator board. According to the indicator board shown in Figure 3, the corresponding intersection is a crossroad, and the three directions ahead are the direction of Chaoyangmen Bridge, the direction of Dongdan, the direction of Dongdan, and the direction of Guomao Bridge, and the intersection has an overpass. If you need to go to Dongdan, you need to follow the directions shown in Figure 3 to make a bridge.

The location of the indicator board needs to be surveyed on the spot, so as to establish the index of each indicator board and the geographical location, and then complete the judgment in step S104.

Step S105, extracting the directional signboard corresponding to the directional signboard from the directional kanban database, wherein the directional signboard is set to highlight the indication information along the direction of the two-dimensional navigation route on the signboard, so as to facilitate identification and attract the attention of the driver. attention.

Taking the indicator board shown in Figure 3 as an example, if the direction of the two-dimensional navigation path is the direction of the Chaoyangmen Bridge going straight, the corresponding direction board is shown in Figure 7. Chaoyangmen Bridge directions are highlighted.

Taking the indicator board shown in Figure 3 as an example, if the direction of the two-dimensional navigation path is the east single direction of turning left, the corresponding direction board is shown in Figure 8. Dongdan instructions are highlighted.

Still taking the indicator board shown in Figure 3 as an example, if the direction of the two-dimensional navigation path is the direction of the Guomao Bridge that turns right, the corresponding direction board is shown in Figure 9, which is opposite to the indicator board shown in Figure 3 and indicates the right turn Information and Guomao Bridge directions are highlighted.

The highlighting may be highlighting, different color display, different line display, adding a different mark, and so on.

In a specific embodiment of the present invention, direction boards corresponding to different two-dimensional navigation paths can be pre-made according to the direction boards, and stored in the direction board database, so as to directly extract corresponding direction boards according to the two-dimensional navigation paths.

In another specific embodiment of the present invention, it is also possible to prefabricate the indicator board as shown in FIG. 3 , and the one-way kanban as shown in FIG. The two-dimensional navigation path shown in Figure 6 is the one-way kanban in the direction of the east direction turning left, and the two-dimensional navigation path shown in Figure 6 is the one-way kanban in the direction of Guomao Bridge turning right and is stored in the directional kanban database, wherein each uni Kanban boards have a different display mode than dashboards. In this way, by superimposing the indicator board shown in Figure 3 and the one-way board shown in Figure 4, the direction board shown in Figure 7 can be obtained to highlight the direction of the straight Chaoyangmen Bridge; by superimposing the indication board shown in Figure 3 and The one-way kanban shown in Figure 5 can be obtained from the directional kanban shown in Figure 8 to highlight the east single direction of the left turn; and by superimposing the indicator board shown in Figure 3 and the one-way kanban shown in Figure 6, it can be obtained The direction board shown in Figure 9 is used to highlight the direction of the Guomao Bridge turning right.

In this embodiment, the indication board is equivalent to the common background board of the corresponding direction signboard, and the one-way signage only has indication information along one driving direction, so as to realize the highlight display of the corresponding indication information after being superimposed. Here, since the one-way kanban has less information, it is beneficial to reduce the amount of data storage.

Correspondingly, extracting the directional kanban corresponding to the directional board from the directional kanban database further includes the following steps:

Step S1051, extracting the instruction board from the directional kanban database, that is, extracting the common background board.

Step S1052, extracting the one-way kanban corresponding to the signboard along the direction of the two-dimensional navigation path from the directional kanban database, wherein the one-way kanban includes the indication information of the signboard along the direction of the two-dimensional navigation path, and has information different from the direction How the board is displayed.

Step S1053, superimposing the extracted instruction board and the extracted one-way kanban to obtain a directional kanban.

Step S106 , with respect to the corresponding intersection ahead, that is, the intersection ahead corresponding to the extracted direction signage, the direction signage is played in advance, so as to forecast the driving direction along the two-dimensional navigation route in advance.

In this step S106, the playing timing may be calculated according to the distance between the current location and the corresponding intersection ahead. For example, the directional signage can be played at a distance of 100 meters to 300 meters from the corresponding front intersection.

In a specific embodiment of the present invention, the above-mentioned directional signage database may be image data, which will greatly reduce the difficulty of implementation compared with setting vectorized real-scene street signs.

In a specific embodiment of the present invention, the above-mentioned direction signage database may belong to the two-dimensional navigation map database, so that the direction signage database functions based on the two-dimensional navigation map. Since the two-dimensional navigation map database has the advantage of covering a wide range, playing direction signs based on the two-dimensional navigation map will have a wider scope of application.

Further, since the true three-dimensional navigation map can more vividly express the increasingly complex urban road form, it can provide a more intuitive guiding path, therefore, within the scope covered by the true three-dimensional navigation map database, the method of the present invention can also Combined with the true 3D navigation map database.

The true 3D navigation database usually includes a true 3D scene database and a true 3D guidance database. The true 3D scene database includes road scene data and building model data, and the road scene data further includes road section scene data and intersection scene data. The road section scene data and the intersection scene data are used to generate a road scene image of a true 3D navigation scene, and the building model data are used to generate a road surrounding scene image of a true 3D navigation scene. The real three-dimensional guidance database can include road section guidance data recording guidance information in road sections, and intersection guidance data recording guidance information in intersections. In addition, the true three-dimensional guidance database can also store information related to generating guidance paths and guidance arrows. Induced information data.

Fig. 2 shows a schematic flow chart of using the joint true three-dimensional navigation map database according to the method of the present invention.

In this embodiment, the method of the present invention also includes the following steps:

Step S201, calculating and generating a three-dimensional guidance route according to the above-mentioned planned two-dimensional navigation route.

Step S202, loading the current road section and the true 3D navigation data ahead along the 3D induced path.

Step S203, synthesizing a true 3D navigation scene with or without a signboard according to the loaded true 3D navigation data.

Specifically, if it is judged in step S104 that there is no indication board, then in step S203, a real three-dimensional navigation scene without a signboard will be synthesized according to the loaded true three-dimensional navigation data; , then the step S203 is to synthesize a true 3D navigation scene including a signboard according to the loaded true 3D navigation data.

In this step, consistent two-dimensional and three-dimensional synchronous navigation can be performed according to the geographic location index established between the two.

The true 3D navigation scene may include a guided path model and a guided arrow generated based on the 3D guided path and the true 3D guided database, so as to provide more intuitive and three-dimensional directional navigation.

Still taking the intersection corresponding to the indicator board shown in Figure 3 as an example, Figure 10 is a schematic diagram of the effect of the true 3D navigation scene corresponding to the 2D navigation path in Figure 8; Figure 11 is a true 3D navigation scene corresponding to the 2D navigation path in Figure 7 FIG. 12 is a schematic diagram of the effect of the real three-dimensional navigation scene corresponding to the two-dimensional navigation path in FIG. 9 .

Further, the method of the present invention may also include the following step S204.

Step S204, playing the true 3D navigation scene with or without the signboard at a larger scale.

For example, the true three-dimensional navigation scene can be played on the display screen of the electronic device at the maximum scale.

Moreover, the direction signboard can be displayed in an enlarged size relative to the corresponding street sign in the real 3D navigation scene, for example, played to the upper half of the real 3D navigation scene, so as to provide a clearer display.

It can be seen that, according to the method of the present invention, the problem that the two-dimensional and three-dimensional navigation electronic maps lack the advance notice of the driver's driving direction during the navigation process can be effectively solved, thereby improving user experience.
