specific embodiment

The following will clearly describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application belong to the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The navigation method provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of a navigation method according to an embodiment of the present application. The navigation method in the embodiment of the present application can be executed by a navigation device, for example, and the navigation device can be set in a smart vehicle.

As shown in Figure 1, the navigation method of this embodiment may include the following steps 1100 to 1300:

Step 1100, during the navigation process, acquire a first position and a second position; the first position is a road target position on the navigation path; the second position is the driver's head position.

Specifically, the navigation route refers to the driving route planned according to the starting point and the end point of the driving set by the driver, and may include multiple road targets in the driving route. The first intersection of the current location, the road target can be, for example, a left-turn intersection, a right-turn intersection, a left fork intersection, a right fork intersection, changing from the current lane to a left-turn/U-turn lane, changing from the current lane Change to the right-turn lane, etc., which are not specifically limited here.

Wherein, the manner of acquiring the first position may include: acquiring positioning data of road objects; and determining the first position according to the positioning data. The positioning data of the road target may be, for example, Global Positioning System (Global Positioning System, GPS) positioning data, sensor positioning data or camera positioning data.

Exemplarily, the GPS positioning data can be obtained based on the global positioning system, the sensor positioning data can be obtained through a distance sensor, and the camera positioning data can be obtained based on a vehicle camera. I won't list them all here.

Wherein, the manner of obtaining the second position may include: obtaining the position parameter of the driver; obtaining the head information of the driver through a sensor; and determining the second position according to the position parameter and the head information.

Specifically, the position parameter of the driver may be, for example, a parameter of the position where the driver sits. The sensor used to obtain the head information of the driver is, for example, a ranging sensor, and the navigation device can locate the position of the driver's head according to the driver's position parameters and the head information obtained by the ranging sensor, that is, the second position .

It should be noted that the timing of obtaining the second location may be after the driver starts the vehicle, or after the driver turns on the navigation function, which is not specifically limited here. After obtaining the second position, the navigation device will project a picture on the display device according to the determined second position, that is, after obtaining the second position, the navigation device can also display the second position.

Wherein, the screen may be a navigation screen or a map screen. The map screen in this embodiment refers to displaying the map of the current area of the vehicle on the display device and displaying the current location of the vehicle in real time on the map when the navigation function is not turned on but the vehicle is started. In this way, the driver can be made aware of the current specific location.

Step 1200, according to the first position and the second position, determine the target display position of the navigation prompt information on the display device; the target display position, the first position and the second position are collinear.

Wherein, the display device may be, for example, smart glasses, a windshield of a vehicle and other devices. This embodiment is described by taking the display device as an example of a windshield.

Specifically, the display position of the navigation prompt information may be determined according to the first position and the second position. As shown in Figure 2, suppose the vehicle moves from position A to position B. The first position is the road target position Y in FIG. 2 , and the second position is X in FIG. 2 .

When the vehicle is at position A, the target display position of the navigation prompt information determined according to the first position and the second position on the display device is S1 in Fig. 2, and it can be seen that X, S1 and Y are located on the same straight line In this way, the navigation prompt information seen by the driver coincides with the road target, which can avoid the situation of missing the turning intersection at the complex intersection.

As the vehicle continues to drive forward, when the vehicle travels to position B, the target display position of the navigation prompt information determined according to the first position and the second position on the display device is S2 in Fig. 2. At this time, it can be seen that X, S2, and Y are still on the same straight line. It can be seen that the navigation prompt information seen by the driver always coincides with the road target, which can avoid missing the turning intersection at complex intersections.

It can be understood that the angle of the road target position Y seen in the driver's field of vision is also constantly moving to the right, that is to say, the angle formed between the straight-line distance between X and Y and the straight line of the road surface is constantly increasing until the vehicle Carry out a turn, wherein, the range change of the included angle can calculate the change of the angle through the GPS plane.

At this time, in order to keep the target display position, the first position and the second position collinear, the target display position of the navigation prompt information displayed on the windshield will move toward the side as the vehicle moves forward. Move, that is, move from S1 to S2.

When turning right at the intersection, the target display position of the navigation prompt information will continuously move to the right side of the windshield; when turning left at the intersection, the target display position of the navigation prompt information will continuously move to the left side of the windshield.

Step 1300, displaying the navigation prompt information at the target display position.

After the target display position of the navigation prompt information is determined, the navigation prompt information is displayed at the target display position on the display device. In practical applications, as the vehicle is started, the target display position of the navigation prompt information will also change in real time.

As shown in Figure 3, when the road target position is on the right side of the current driving direction, that is, when turning right, the navigation prompt information seen by the driver coincides with the road target. And miss the right-turn intersection, resulting in wrong itinerary and improving user experience.

It should be noted that after the navigation prompt information is displayed at the target display position, there may be two cases where the driver does not move to the road target according to the navigation prompt information, or the driver moves to the road target according to the navigation prompt information.

Exemplarily, taking the road target as a right-turn intersection as an example, if the driver does not move to the road target according to the navigation prompt information, the navigation prompt information indicates that a right turn is required, but the driver keeps going straight, then the navigation prompt The target display position of the information will be adjusted in real time with the change of the vehicle position and the target position of the road, and the target display position of the navigation prompt information will be more and more to the right.

Exemplarily, taking the road target as a right-turn intersection as an example, when the driver does not move to the road target according to the navigation prompt information, the navigation prompt information indicates that a right turn is required, and the driver finds that it is necessary to move right, and turns the front of the car towards the road The target moves. At this time, because the vehicle moves to the right, it can ensure that the driver's head position, the road target position, and the target display position of the navigation prompt information are in a straight line, and there is no need to move the target display position of the navigation prompt information. .

It should be noted that, the navigation method provided in the embodiment of the present application may be executed by a navigation device, or a control module in the navigation device for executing the navigation method. In the embodiment of the present application, the navigation device provided in the embodiment of the present application is described by taking the navigation device executing the navigation method as an example.
