Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The technical solution of the present disclosure is explained in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

In view of the above technical problems, the present disclosure is directed to provide a method, an apparatus, an electronic device, and a storage medium for roundabout route navigation, which enable a user to more intuitively obtain correct roundabout guiding information and avoid the user missing a correct exit of the roundabout. The method provided by the disclosure can be applied to vehicles with navigation functions, electronic navigation equipment, terminals with navigation functions and the like.

Fig. 1 is a schematic view of an application scenario in which the roundabout route navigation method according to the embodiment of the present disclosure can be implemented, and as shown in fig. 1, for a complex driving scenario such as a roundabout, navigation in the prior art cannot well indicate intersection information. The method and the device have the advantages that the user can visually see the driving condition of the vehicle in the roundabout from the three-dimensional top view of the roundabout route under the three conditions of coming into the roundabout route, being in the roundabout route, coming off the roundabout and the like, so that the user can more visually acquire correct roundabout guiding information, and the user is prevented from missing a correct exit of the roundabout.

Before the roundabout is driven in, the terminal can also acquire a first distance between the current position of the vehicle and the roundabout in the rest driving path. When the first distance is smaller than a first preset threshold value, the terminal can display an indication icon of the roundabout AR on the navigation interface at the moment so as to remind the user that the vehicle is about to enter the roundabout. In this way, the user can expect the psychological road driving when about to enter the rotary island in a visual perception mode, so that the user can slow down the driving speed to a certain extent and keep track of the prompt information of the navigation information.

And if the current position of the vehicle is in the roundabout route, displaying a three-dimensional top view of the roundabout route on the navigation interface. The three-dimensional top view of the roundabout route comprises real-time road information of vehicles. The three-dimensional top view of the roundabout route enables a user to visually see the driving condition of the vehicle in the roundabout, so that the user can conveniently obtain correct roundabout guiding information, and the user is prevented from missing a correct exit of the roundabout. Wherein the real-time road information of the vehicle includes: the position of the vehicle in the three-dimensional top view of the roundabout route, the remaining distance between the vehicle and the target exit, and the travel path of the vehicle to the target exit.

When the current position of the vehicle is in the roundabout route, the terminal can obtain a second distance between the current position of the vehicle and a target outlet in the roundabout route according to a preset sampling period. For example, the second distance between the current position of the vehicle and the target exit in the roundabout line is acquired every 5 seconds. And judging whether the vehicle is about to drive away from the roundabout or not according to the second distance. And when the second distance is smaller than a second preset threshold value, displaying an exit AR indication icon on the navigation interface to strengthen the guiding capacity and remind the user that the vehicle is about to enter the rotary island. Wherein the exit AR indication icon includes: a turn icon, and/or a point-to-stream arrow.

Meanwhile, the terminal can also broadcast real-time road information of the vehicle through voice according to a preset time interval, and remind a user of entering the roundabout, driving away from the roundabout and the like.

The application provides a method, a device, electronic equipment and a storage medium for navigation of a roundabout route, which relate to the technical field of automatic driving, computer vision and voice, and the technical problems that in the prior navigation technology, a user can only roughly know possible exit directions, so that the correct exit positions are frequently missed and inconvenience is brought to the driver are solved by applying the method.

Fig. 2 is a schematic diagram of a first embodiment of the present disclosure, and as shown in fig. 2, the method in this embodiment may include:

s101, acquiring the current position of the vehicle.

And S102, responding to the current position of the vehicle in the roundabout route, and displaying a three-dimensional top view of the roundabout route on the navigation interface.

The method in the embodiment can be applied to vehicles with navigation functions, electronic navigation equipment, terminals with navigation functions and the like. In the present embodiment, a terminal having a navigation function is described as an example. First, the terminal can acquire the current position of the vehicle in real time, for example, the current position of the vehicle through a Global Positioning System (GPS). And then, judging the current position of the vehicle, and if the current position of the vehicle is in the roundabout route, displaying a three-dimensional top view of the roundabout route on a navigation interface. The three-dimensional top view of the roundabout route comprises real-time road information of vehicles. The three-dimensional top view of the roundabout route enables a user to visually see the driving condition of the vehicle in the roundabout, so that the user can conveniently obtain correct roundabout guiding information, and the user is prevented from missing a correct exit of the roundabout.

In this embodiment, the real-time road information of the vehicle includes: the position of the vehicle in the three-dimensional top view of the roundabout route, the remaining distance between the vehicle and the target exit, and the travel path of the vehicle to the target exit.

Illustratively, after the vehicle drives into the roundabout, the real-time road information of the current roundabout is displayed on the terminal interface, and the guidance path of the whole vehicle in the roundabout is prompted again, so that not only is the intersection position of the current user informed, but also the correct exit direction of the driver is informed, and the user can fully know the information of the road to be driven out. Fig. 3 is a schematic view of a navigation interface of a vehicle within a roundabout route according to an embodiment of the present disclosure, as shown in fig. 3, where the position of the vehicle in a three-dimensional top view of the roundabout route and the travel path of the vehicle to a target exit are displayed in the interface. The display form of the three-dimensional top view of the roundabout route may be various, that is, the top view as shown on the right side or the thumbnail as shown on the upper left corner. A full view of the roundabout route, including the travel route from exit to entrance, may be displayed on the thumbnail. Meanwhile, the remaining distance between the vehicle and the target exit can be displayed in real time, such as 'Nanjing West street' and '102 meters' shown in the upper left corner of the figure.

In the present embodiment, the display form of the travel path for the vehicle to reach the target exit is different from the display form of the path that the vehicle has traveled; the display form comprises: line type, color, shadow effect.

For example, on the navigation terminal, the traveling path of the vehicle to the target exit may be distinguished from the path that the vehicle has traveled by displaying the line type, color, shading effect, and the like. As shown in fig. 3, in a three-dimensional top view of the roundabout route, a circle represents a current position of the vehicle, an arrow direction represents a vehicle head direction, and a color of a traveling path of the vehicle to the target exit is different from a color of a path that the vehicle has traveled. Therefore, the user can visually see the driving path of the vehicle from the current position to the target exit, the driving path is clearly distinguished from the driving path of the vehicle, and the user can quickly distinguish the position of the vehicle in the rotary island.

In this embodiment, the terminal may voice-broadcast the real-time road information of the vehicle according to a preset time interval.

For example, the terminal may perform voice broadcast at preset time intervals. For example, the remaining distance between the vehicle and the target exit, the road congestion condition, the roundabout exit condition, and the like are broadcast every 5 seconds. Therefore, when a user drives a vehicle, the user does not need to pay too much attention to the navigation display interface, real-time road information of the vehicle is reminded by voice on the premise of ensuring safe driving, and the user is prevented from missing a target exit in the roundabout.

In the embodiment, the current position of the vehicle is obtained; displaying a three-dimensional top view of the roundabout route on the navigation interface in response to the current position of the vehicle being within the roundabout route; the three-dimensional top view of the roundabout route comprises real-time road information of vehicles. The technical problem that in the prior navigation technology, a user can only roughly know the possible exit direction, so that the correct exit position is often missed and inconvenience is brought to a driver is solved, and the technical effects that the user can intuitively acquire correct rotary island guide information and the user misses the correct exit of the rotary island are achieved by enabling the user to intuitively see the driving condition of the vehicle in the rotary island from the three-dimensional top view of the rotary island route.

When the first distance is smaller than a first preset threshold value, the terminal can display an indication icon of the roundabout AR on the navigation interface at the moment so as to remind the user that the vehicle is about to enter the roundabout. In this way, the user can expect the psychological road driving when about to enter the rotary island in a visual perception mode, so that the user can slow down the driving speed to a certain extent and keep track of the prompt information of the navigation information. Fig. 5 is a schematic view of a navigation interface before a vehicle enters a roundabout route according to an embodiment of the present disclosure, and as shown in fig. 5, a roundabout indication icon may be used to remind a user that the vehicle is about to enter the roundabout, and an entrance and a target exit corresponding to a roundabout driving path may also be indicated in the icon. Therefore, the user can visually see the driving condition of the vehicle in the rotary island from the AR indication icon of the rotary island, the user can more visually acquire correct rotary island guide information, and the technical effect that the user misses a correct exit of the rotary island is avoided.

Therefore, the method can attract the attention of the user to remind the user that the vehicle is about to enter the roundabout, the time for the user to pay attention to the navigation interface is reduced, and the user is prevented from missing the roundabout while safe driving is guaranteed. Wherein, the rotary island prompt message includes: the front is about to enter the rotary island, and the speed reduction is noticed.
