Detailed Description
To further explain the technical means and effects of the present application for achieving the intended application, the following detailed description is given for the embodiments, methods, steps, structures, features and effects of the virtual navigation method and system according to the present application with reference to the accompanying drawings and preferred embodiments.
The foregoing and other technical matters, features and effects of the present application will be apparent from the following detailed description of preferred embodiments, which is to be read in connection with the accompanying drawings. While the present application is susceptible to embodiment and specific details, specific reference will now be made in detail to the present disclosure for the purpose of illustrating the general principles of the invention.
FIG. 1 is a flow diagram illustrating a virtual navigation method in accordance with an exemplary embodiment. Referring to fig. 1, the virtual navigation method of the present embodiment includes, but is not limited to, the following steps:
and step 130, if yes, after the vehicle reaches a preset position before the next intersection, displaying a virtual navigation mark for indicating the current traveling direction in front of the vehicle through a second display device.
In step 110, the user obtains a planned route from the current position to the destination by inputting the destination, the system displays at least one planned route from the current position to the destination through the first display device after completing route planning, and the system takes the route selected by the user as the current navigation route and starts navigation after the user selects one of the routes and clicks to start navigation. In this embodiment, the first display device is a vehicle-mounted liquid crystal display device, and is connected to the processing module of the system to display the navigation route and related information according to the navigation data, so that the user can know information such as the direction, intersection indication, distance, vehicle speed, and the like of the route through the navigation route displayed by the first display device, and the manner of displaying the navigation route through the first display device is known by those skilled in the art, and is not described herein again.
In step 120, after the navigation is started, the system determines the type of the next intersection according to the current navigation route, and in this embodiment, determining whether the next intersection is an intersection of a preset type according to the navigation route includes:
acquiring the traveling direction of the next intersection, the type of the fork intersection and the type number of the intersection sections according to the navigation route;
and if the traveling direction of the next intersection, the type of the fork intersection and the type number of the intersection sections accord with the preset combination, determining that the next intersection is the intersection of the preset type.
The next intersection is the next intersection, the traveling direction of the next intersection is based on the current traveling direction and comprises turning and straight traveling, wherein the turning can be left-front, right-front, turning and the like, the intersection section refers to a section of road which intersects at the next intersection, the type of the section of road can be high speed, common road, overhead, express way and the like, and the combination of the traveling direction of the next intersection, the type of the intersection and the type number of the intersection section determines the direction judgment difficulty of the next intersection. In this embodiment, the preset combination includes that the traveling direction is turning, any intersection type is provided, and the number of types of the intersection sections is greater than or equal to one, or that the traveling direction is straight, the intersection type is a non-intersection, and the number of types of the intersection sections is greater than or equal to one. For example, the next intersection is a three-way intersection, a common road intersects with an overhead and the traveling direction is right ahead, or the next intersection is an intersection, the common road intersects with the overhead and the traveling direction is right turn, which can be a preset combination that the traveling direction is a turning direction, the type of any intersection is changed, and the number of types of the intersected road sections is greater than or equal to one. For example, the next intersection is a three-way intersection, a normal road intersects with an overhead and the traveling direction is straight, or the next intersection is a three-way intersection, a normal road intersects and the traveling direction is straight, which can correspond to a preset combination in which the traveling direction is straight, the type of the intersection is a non-crossroad and the number of types of the intersected road segments is greater than or equal to one, and the case in which the next intersection is a crossroad and is straight does not belong to the preset combination. By the method, virtual navigation can be selectively performed on different types of intersections, so that judgment of a user is not influenced, and driving sight and attention of the user are not influenced.
In step 130, after determining that the next intersection is the intersection of the preset type, the system confirms a preset position before the next intersection, for example, a fixed distance of 50 meters, 20 meters, etc. before the intersection or a reasonable distance calculated according to the vehicle speed, and the preset position is used as a starting point for starting displaying the virtual navigation mark. In this embodiment, after the next intersection is determined to be the intersection of the preset type, the preset position is calculated according to the real-time vehicle speed and the position of the next intersection, generally speaking, the faster the vehicle speed is, the farther the preset position is from the intersection, otherwise, the closer the preset position is, the preset position may be changed in real time or not calculated before the vehicle is at the preset distance from the intersection, the value is calculated and locked after the vehicle is at the preset distance from the intersection, and in the vehicle driving process, the vehicle position is monitored to determine whether the vehicle reaches the preset position.
In step 130, after the vehicle reaches a preset position before the next intersection, displaying a virtual navigation mark for indicating the current traveling direction in front of the vehicle through a second display device, including:
after the vehicle reaches a preset position before the next intersection, acquiring the position of the vehicle, the advancing direction of the next intersection and map data corresponding to the next intersection;

and performing virtual reality display on the navigation identification data through a second display device to form a virtual navigation identification for indicating the current traveling direction in front of the vehicle.
The position of the next intersection and the position of the intersection section of the intersection in a coordinate system with the vehicle as the origin can be determined according to the position of the vehicle and the map data corresponding to the next intersection, the corresponding navigation mark is drawn according to the traveling direction of the next intersection, and the navigation mark data are generated and sent to the second display device for display. The second display device is, for example, a head-up display device with a virtual reality function, which can project the navigation mark on the windshield or other positions of the vehicle, so that the navigation mark can be displayed in the front of the vehicle in a virtual reality manner, and from the visual perception of the driver, the navigation mark is more direct and accurate compared with the navigation route viewed on the first display device as if the road needing to be continued is virtually drawn in the front of the vehicle.
In an embodiment, the virtual navigation method of the present application further includes:
receiving an operation signal for turning on/off a virtual navigation function when a navigation is turned on or after the navigation is started;
and responding to the operation signal according to the current use state of the virtual navigation function to turn on/off the virtual navigation function.
Wherein, the user can turn on or off the virtual navigation function according to the requirement. For example, the initialization state of the virtual navigation function is off, when the user starts the navigation system, the system confirms to the user whether the virtual navigation function needs to be started, if the user does not respond, the virtual navigation function is kept off, if the user clicks on the virtual navigation function, the virtual navigation function is started, and then, the corresponding virtual navigation identifier is displayed through the second display device whenever the navigation system reaches the preset type of intersection. Or, after the user uses the navigation and starts the virtual navigation function, if the virtual navigation function is not needed during driving, the user can select to turn off the virtual navigation function, and then the navigation system only displays the navigation route and the related information on the first display device.
According to the virtual navigation method, after navigation is started, the current navigation route is displayed through the first display device, whether the next intersection is the intersection of the preset type or not is judged according to the navigation route, and if yes, after the vehicle reaches the preset position in front of the next intersection, the virtual navigation mark used for indicating the current traveling direction is displayed in front of the vehicle through the second display device.
