[0025] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0027] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0028] Speeding electronic eye information is a kind of beyond-visual-range information from the navigation system, which will be output to the driver before the vehicle reaches the speeding electronic eye. In one example, it can be output to the driver 300 meters before the vehicle reaches the speeding electronic eye, so that the driver can have enough time to slow down and avoid speeding tickets. The navigation system can output speeding electronic eye information regardless of whether the vehicle is in navigation mode (the vehicle has set a navigation path) or cruising mode (no navigation path is set).

[0029] In an embodiment of the present application, the speeding electronic eye information output by the navigation system may include the elevated positioning result of the speeding electronic eye in addition to the speed limit information and speeding photography information of the speeding electronic eye. The speed limit information of the speeding electronic eye is used to indicate the maximum driving speed of the road where the speeding electronic eye is located. The speeding photography information of the speeding electronic eye is used to indicate that the speeding electronic eye will take a photo of the vehicle if the vehicle exceeds the speed limit. The elevated positioning result of the speeding electronic eye is used to indicate whether the speeding electronic eye is located on or under the viaduct. In this way, by adding the elevated positioning result of the speeding electronic eye to the speeding electronic eye information output by the navigation system, the navigation display device can determine whether the speeding electronic eye information output by the navigation system matches the current driving road of the vehicle based on the elevated positioning result of the speeding electronic eye in the speeding electronic eye information output by the navigation system, thereby improving the prompt accuracy of the speeding electronic eye.

[0030] The Most Probable Path (MPP) represents the path that the vehicle is most likely to drive on. In navigation mode, the navigation display device will use the navigation path as the MPP; in cruise mode, the navigation display device will calculate the main path based on its own logic, and generally set the current straight route as the MPP.

[0031] It can be understood that in the navigation state, the vehicle's driving road is basically consistent with the MPP. Therefore, the navigation display device directly uses the speeding electronic eye information output by the navigation system to provide speeding electronic eye prompts, which is basically accurate. However, in the viaduct area scene in the cruising state, due to the high positioning accuracy of the navigation system, it is impossible to accurately identify whether the vehicle is on the viaduct or under the viaduct. There may be two failure scenarios, resulting in poor accuracy of the speeding electronic eye prompt: one is that the vehicle is driving on the road on the viaduct but the navigation system outputs the speeding electronic eye information of the road under the viaduct; the other is that the vehicle is driving on the road under the viaduct but the navigation system outputs the speeding electronic eye information of the road on the viaduct.

[0032] Based on this, the embodiments of the present application provide a navigation display method, device, equipment, medium and product, which can improve the accuracy of the speeding electronic eye prompts in the elevated bridge area scene under cruising state, and thus improve the accuracy of the navigation display.

[0033] The navigation display method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0034] See also Figure 1 , Figure 1 is a flowchart of the navigation display method provided by the embodiment of the present application. Figure 1 As shown, the navigation display method may include the following steps:

[0035] Step 101: When a vehicle is in a cruising state and traveling on an elevated bridge area, first real scene information of the driving road of the vehicle is collected.

[0036] The navigation display device can monitor the navigation state of the vehicle and the driving area of ​​the vehicle. The navigation state of the vehicle can be a navigation state or a cruise state; the driving area of ​​the vehicle can be an elevated bridge area or a non-elevated bridge area.

[0037] In specific implementation, the navigation state of the vehicle can be determined by judging whether a navigation path is set in the navigation system. If the navigation path is set in the navigation system, it can be determined that the vehicle is in the navigation state; if the navigation path is not set in the navigation system, it can be determined that the vehicle is in the cruising state.

[0038] The driving area of ​​the vehicle can be determined by obtaining the geographical location information of the vehicle. If the geographical location information of the vehicle is the geographical location information of the elevated bridge area, it can be determined that the vehicle is driving in the elevated bridge area; if the geographical location information of the vehicle is not the geographical location information of the elevated bridge area, it can be determined that the vehicle is driving in the non-elevated bridge area.

[0039] As mentioned above, when the vehicle is in a cruising state and driving on an elevated bridge area, the navigation system may not be able to accurately identify whether the vehicle is on or under the elevated bridge due to the high positioning accuracy of the navigation system, resulting in the speeding electronic eye information output by the navigation system not being the speeding electronic eye information of the vehicle's driving road, resulting in poor accuracy of the speeding electronic eye prompt. In order to improve the accuracy of the speeding electronic eye prompt in this case, the elevated positioning result of the vehicle can be determined by collecting the real-life information of the vehicle's driving road to improve the accuracy of the vehicle's elevated positioning.

[0040] In specific implementation, the real scene information of the road on which the vehicle is traveling can be collected through an image acquisition device. For the convenience of description, this real scene information is referred to as the first real scene information, and the real scene information can also be referred to as visual information. The first real scene information can include but is not limited to at least one of the following: traffic signs, such as pedestrian signs, stop and yield signs, slow down and yield signs, minimum speed limit signs, speed limit signs, etc.; traffic markings, such as crosswalks, etc.; signal lights, such as traffic lights; road users, such as pedestrians, cyclists, vehicles, etc.; intersections, such as crossroads, on-ramp entrances, off-ramp entrances, etc.; isolation belts, etc.

[0041] In the embodiment of the present application, the navigation display device may be a vehicle or a user terminal. When the navigation display device is a vehicle, the image acquisition device may be, but is not limited to, a front-view camera of the vehicle. When the navigation display device is a user terminal, the image acquisition device may be, but is not limited to, a rear-view camera of the user terminal.

[0042] Step 102: Determine a first elevated positioning result of the vehicle according to the first real scene information.

[0043] It can be understood that there are differences in the real-life information of the road on the viaduct and the road under the viaduct, such as: the ground, intersections, pedestrian crossings, pedestrian attention signs, stop and yield signs, slow down and yield signs, pedestrians, on-ramp entrances, cyclists, traffic lights, etc. belong to the real-life information of the road under the viaduct, and the minimum speed limit sign, speed limit sign above 80kph, expressway exit sign and off-ramp entrance belong to the real-life information of the road on the viaduct. Therefore, the elevated positioning result of the vehicle can be determined by the collected real-life information of the vehicle's driving road, and this elevated positioning result can be used as the standard elevated positioning result. For the convenience of description, this elevated positioning result is called the first elevated positioning result.

[0044] The first elevated positioning result of the vehicle may indicate whether the driving road of the vehicle is located on the viaduct or under the viaduct. Therefore, the first elevated positioning result may be on the viaduct or under the viaduct.

[0045] Step 103: Obtain the second elevated positioning result of the first speeding electronic eye output by the navigation system.

[0046] As described above, in an embodiment of the present application, attribute information of an elevated positioning result of a speeding electronic eye is added to the speeding electronic eye information output by the navigation system.

[0047] In specific implementation, the navigation system can locate the vehicle to obtain the elevated positioning result of the vehicle, then search for the speeding electronic eye on the road corresponding to the elevated positioning result, and output the speeding electronic eye information. Therefore, it can be understood that the elevated positioning result of the speeding electronic eye output by the navigation system is the elevated positioning result of the vehicle determined by the navigation system based on the geographical location information of the located vehicle.

[0048] In step 103, the speeding electronic eye information output by the navigation system is information of the first speeding electronic eye, including the elevated positioning result of the first speeding electronic eye. For the convenience of description, this elevated positioning result is referred to as the second elevated positioning result. The first speeding electronic eye may include one or more speeding electronic eyes.

[0049] The second elevated positioning result of the first speeding electronic eye can indicate whether the first speeding electronic eye is located on the viaduct or under the viaduct. Therefore, the second elevated positioning result can be on the viaduct or under the viaduct.

[0050] Step 104: display the speed limit information and speeding photography information of the target speeding electronic eye according to the matching result of the first elevated positioning result and the second elevated positioning result; the elevated positioning result of the target speeding electronic eye matches the first elevated positioning result.

[0051] After obtaining the first elevated positioning result and the second elevated positioning result, the first elevated positioning result and the second elevated positioning result can be matched based on the first elevated positioning result to determine whether the first elevated positioning result and the second elevated positioning result are consistent, and then decide whether to display the speed limit information and speeding camera information of the first speeding electronic eye output by the navigation system to ensure that the speeding electronic eye information prompted is the speeding electronic eye information of the vehicle's driving road, thereby improving the prompt accuracy of the speeding electronic eye, and then improving the accuracy of the navigation display.

[0052] The target speeding electronic eye can be determined based on the matching results of the first elevated positioning result and the second elevated positioning result. The target speeding electronic eye may be the first speeding electronic eye or other speeding electronic eyes. The specific implementation can be found in the relevant description below and will not be described here.

[0053] In some embodiments, the navigation display device can display the speed limit information and speeding photo information of the target speeding electronic eye through its own components. In the case where the navigation display device is a vehicle, the vehicle can display the speed limit information and speeding photo information of the target speeding electronic eye on the dashboard or human machine interface (HMI). In one example, Figure 2 As shown, the speed limit information and speeding photo information of the target speeding electronic eye are displayed in the instrument panel. In the case where the navigation display device is a user terminal, the user terminal can display the speed limit information and speeding photo information of the target speeding electronic eye on the screen.

[0054] In other embodiments, the navigation display device can also display the speed limit information and speeding photo information of the target speeding electronic eye through other devices, such as: when the navigation display device is a vehicle, the vehicle can display the speed limit information and speeding photo information of the target speeding electronic eye through the user terminal; when the navigation display device is a user terminal, the user terminal can display the speed limit information and speeding photo information of the target speeding electronic eye through the vehicle.

[0055] The navigation display method of this embodiment takes into account the problem of difficult positioning in the elevated bridge area. When the vehicle is in a cruising state and driving in the elevated bridge area, on the one hand, the elevated positioning result of the vehicle can be determined by collecting the real-life information of the vehicle's driving road; on the other hand, the elevated positioning result of the speeding electronic eye can be added to the speeding electronic eye information output by the navigation system. Then, the displayed speeding electronic eye information can be determined by determining whether the two elevated positioning results match, so that the elevated positioning result of the speeding electronic eye corresponding to the displayed speeding electronic eye information matches the elevated positioning result determined based on the real-life information of the vehicle's driving road. In this way, it can be ensured that the prompted speeding electronic eye information is the speeding electronic eye information of the vehicle's driving road, thereby improving the prompt accuracy of the speeding electronic eye, and further improving the accuracy of the navigation display.

[0056] The following is a detailed description of the determination of the target speeding electronic eye.

[0057] In some embodiments, displaying the speed limit information and speeding photo taking information of the target speeding electronic eye according to the matching result of the first elevated positioning result and the second elevated positioning result includes:

[0058] When the first elevated positioning result and the second elevated positioning result match, the speed limit information and speeding photo taking information of the first speeding electronic eye are displayed.

[0059] The first elevated positioning result and the second elevated positioning result match, that is, the first elevated positioning result and the second elevated positioning result are consistent, which means that the navigation system's elevated positioning result for the vehicle is accurate. The first speeding electronic eye is the speeding electronic eye on the vehicle's driving road. Therefore, the information of the first speeding electronic eye can be displayed to realize the prompt of the speeding electronic eye on the vehicle's driving road, thereby improving the prompt accuracy of the speeding electronic eye, and thus improving the accuracy of the navigation display.

[0060] It can be understood that in these embodiments, the target super-speed electronic eye is the first super-speed electronic eye.

[0061] In some other embodiments, the speed limit information and speeding photography information of the target speeding electronic eye are displayed according to the matching result of the first elevated positioning result and the second elevated positioning result; the elevated positioning result of the target speeding electronic eye matches the first elevated positioning result, including:

[0062] In the case where the first elevated positioning result and the second elevated positioning result do not match, transmitting the first elevated positioning result to the navigation system, so that the navigation system determines a second speeding electronic eye based on the first elevated positioning result, and the elevated positioning result of the second speeding electronic eye matches the first elevated positioning result;

[0063] The speed limit information and speeding camera information of the second speeding electronic eye output by the navigation system are displayed.

[0064] The first elevated positioning result and the second elevated positioning result do not match, that is, the first elevated positioning result and the second elevated positioning result are inconsistent, which means that the navigation system's elevated positioning result for the vehicle is inaccurate, and the first speeding electronic eye is not the speeding electronic eye on the vehicle's driving road. Therefore, in order to ensure that the prompted speeding electronic eye information is the speeding electronic eye information of the vehicle's driving road, the navigation display device will not display the information of the first speeding electronic eye.

[0065] In order to realize the prompt of the speeding electronic eye on the road where the vehicle is traveling, the navigation display device can transmit the first elevated positioning result to the navigation system, so that the navigation system corrects its own elevated positioning result of the vehicle to the first elevated positioning result, and then searches for the speeding electronic eye on the road corresponding to the first elevated positioning result, obtains the second speeding electronic eye, and then outputs the information of the second speeding electronic eye. It can be understood that since the second speeding electronic eye is searched by the navigation system based on the first high-speed positioning result, the elevated positioning result of the second speeding electronic eye is the first high-speed positioning result, and the second speeding electronic eye is the speeding electronic eye on the road where the vehicle is traveling, therefore, the information of the second speeding electronic eye can be displayed to realize the prompt of the speeding electronic eye on the road where the vehicle is traveling, improve the prompt accuracy of the speeding electronic eye, and thus improve the accuracy of the navigation display.

[0066] It can be understood that in these embodiments, the target super-speed electronic eye is the second super-speed electronic eye.

[0067] The determination of the first elevated positioning result is described in detail below.

[0068] In some embodiments, determining a first elevated positioning result of the vehicle according to the first real scene information may include:

[0069] Acquire a real scene database; wherein the real scene database includes at least one real scene information, and the corresponding relationship between each real scene information and the viaduct and the viaduct;

[0070] Search the real scene database according to the first real scene information to obtain a search result;

[0071] A first elevated positioning result of the vehicle is determined according to the retrieval result.

[0072] In these embodiments, the navigation display device may pre-store a real-view database, which may include at least one piece of real-view information, and a correspondence between the real-view information and the viaduct (hereinafter referred to as the first correspondence), and a correspondence between the real-view information and the viaduct (hereinafter referred to as the second correspondence).

[0073] The correspondence relationship can be expressed as corresponding or non-corresponding. It is worth noting that for the same real scene information, the first correspondence relationship and the second correspondence relationship are opposite, that is, if the first correspondence relationship of a certain real scene information is corresponding, that is, the real scene information corresponds to the viaduct, that is, the real scene information is the real scene information of the road on the viaduct, then the second correspondence relationship of the real scene information is non-corresponding, that is, the real scene information does not correspond to the underside of the viaduct, that is, the real scene information is not the real scene information of the road under the viaduct; vice versa.

[0074] In a specific implementation, after collecting the first real scene information, the navigation display device can search the real scene database according to the first real scene information, retrieve the first corresponding relationship and the second corresponding relationship of the first real scene information from the real scene database, and obtain the search result of the first real scene information. Then, the first elevated positioning result of the vehicle is determined according to the search result of the first real scene information, so that the accuracy of determining the first elevated positioning result can be improved, thereby improving the prompt accuracy of the speeding electronic eye, and further improving the accuracy of the navigation display.

[0075] Further, determining the first elevated positioning result of the vehicle according to the search result may include:

[0076] If the first real scene information is retrieved from the real scene database and corresponds to an elevated bridge, the first elevated positioning result is determined as being on an elevated bridge;

[0077] If the first real scene information is retrieved from the real scene database and corresponds to under the viaduct, the first viaduct positioning result is determined to be under the viaduct.

[0078] In specific implementation, if the retrieval result of the first real scene information is that the first correspondence of the first real scene information is corresponding or the second correspondence is not corresponding, that is, the first real scene information corresponds to the viaduct, it means that the first real scene information is the real scene information of the road on the viaduct. Therefore, the first viaduct positioning result can be determined as on the viaduct.

[0079] If the search result of the first real scene information is that the first correspondence of the first real scene information is not corresponding or the second correspondence is corresponding, that is, the first real scene information corresponds to under the viaduct, it means that the first real scene information is the real scene information of the road under the viaduct. Therefore, the first viaduct positioning result can be determined as under the viaduct.

[0080] It can be seen that through the above method, the accurate determination of the first elevated positioning result can be achieved, thereby improving the accuracy of the speeding electronic eye's prompts, and further improving the accuracy of the navigation display.

[0081] The embodiments of the present application do not limit the real scene information in the real scene database, which may include some or all possible real scene information on and under the viaduct. In some embodiments, the real scene database may include at least one of the following real scene information: intersections, crosswalks, pedestrian attention signs, stop and yield signs, slow down and yield signs, pedestrians, on-ramp entrances, cyclists, traffic lights, minimum speed limit signs, speed limit signs above 80kph, expressway exit signs, and off-ramp entrances;

[0082] The corresponding relationship between the second real scene information and the viaduct is not corresponding, and the corresponding relationship between the second real scene information and the viaduct is corresponding; the second real scene information may include at least one of the following: the intersection, the crosswalk, the pedestrian attention sign, the stop and yield sign, the slow down and yield sign, the pedestrian, the on-ramp, the cyclist, and the traffic light;

[0083] The third real scene information corresponds to the one on the viaduct, and the third real scene information does not correspond to the one under the viaduct; the third real scene information may include at least one of the following: the minimum speed limit sign, the speed limit sign above 80kph, the expressway exit sign and the off-ramp.

[0084] In addition, the embodiment of the present application does not show the data storage method of the real scene database, and its data storage method can be text or table. In an example, the real scene database can be as shown in Table 1:

[0085] Table 1: Real scene database.

[0086] Real-time information On the elevated Under the elevated crossroads N Y pedestrian crossing N Y Pedestrians warning sign N Y Stop and yield sign N Y Slow down and give way sign N Y Pedestrian Target N Y On-ramp entrance N Y Cyclist's goal N Y traffic light N Y Minimum speed limit sign Y N Speed ​​limit sign above 80kph Y N Expressway exit sign Y N Off-ramp Y N

[0087] In Table 1, N indicates corresponding, and Y indicates not corresponding.

[0088] The real scene information in the real scene database in the above embodiment, and the corresponding relationship between the real scene information and the viaduct and under the viaduct respectively conform to the actual road conditions in the viaduct area. Therefore, by determining the first viaduct positioning result through the above real scene database, the accuracy of the first viaduct positioning result can be improved.

[0089] In some other embodiments, determining the first elevated positioning result of the vehicle according to the first real scene information may include:

[0090] Obtaining a first information database corresponding to the viaduct and a second information database under the viaduct;

[0091] According to the first real scene information, searching is performed in the first information database and the second information database,

[0092] In the case where information matching the first real scene information is retrieved in the first information database, determining the first elevated positioning result as being on an elevated bridge;

[0093] When information matching the first real-scene information is retrieved from the second information database, the first elevated positioning result is determined to be under the elevated bridge.

[0094] In these embodiments, corresponding real scene information may be collected on and under the viaduct respectively, and then the real scene information on the viaduct may be combined to obtain a first information library, and the real scene information under the viaduct may be combined to obtain a second information library.

[0095] The embodiments of the present application do not limit the real scene information included in the first information library and the second information library. In some embodiments, the first information library may include the second real scene information, and the second information library may include the third real scene information.

[0096] After the first real scene information of the road on which the vehicle is currently traveling is collected, it can be searched in the first information database and the second information database respectively to determine the first elevated positioning result.

[0097] If the first real scene information is retrieved in the first information database, it means that the first real scene information is the real scene information of the road on the viaduct. Therefore, the first viaduct positioning result can be determined as being on the viaduct.

[0098] If the first real scene information is retrieved in the second information database, it means that the first real scene information is the real scene information of the road under the viaduct. Therefore, the first viaduct positioning result can be determined as under the viaduct.

[0099] It can be seen that through the above method, the accurate determination of the first elevated positioning result can be achieved, thereby improving the accuracy of the speeding electronic eye's prompts, and further improving the accuracy of the navigation display.

[0100] In some further embodiments, determining the first elevated positioning result of the vehicle according to the first real scene information may include:

[0101] In a case where the first real scene information includes the first information, determining that the first elevated positioning result of the vehicle is under an elevated bridge;

[0102] In a case where the first real scene information includes the second information, determining that the first elevated positioning result of the vehicle is on an elevated bridge;

[0103] The first information is information that exists under the viaduct but not on the viaduct; the second information is information that exists on the viaduct but not under the viaduct.

[0104] In these embodiments, the navigation display device can pre-acquire information that is specific to under the viaduct (i.e., exists under the viaduct but not on the viaduct), and information that is specific to on the viaduct (i.e., exists on the viaduct but not under the viaduct), wherein the information specific to under the viaduct may, but is not limited to, include the first information, and the information specific to on the viaduct may, but is not limited to, include the second information.

[0105] The embodiments of the present application do not limit the specific information types of the information that is exclusive to the viaduct and the information that is exclusive to the viaduct. In some embodiments, the information that is exclusive to the viaduct may include, but is not limited to, at least one of the following: a crossroad, a pedestrian crossing, a pedestrian attention sign, a stop and yield sign, a slow down and yield sign, a pedestrian, an on-ramp, a cyclist, and a traffic light. The information that is exclusive to the viaduct may include, but is not limited to, at least one of the following: a minimum speed limit sign, a speed limit sign above 80 kph, an expressway exit sign, and an off-ramp. Further, the first information may include at least one of the following: a crossroad, a pedestrian crossing, a pedestrian attention sign, a stop and yield sign, a slow down and yield sign, a pedestrian, an on-ramp, a cyclist, and a traffic light; the second information may include at least one of the following: a minimum speed limit sign, a speed limit sign above 80 kph, an expressway exit sign, and an off-ramp.

[0106] If the first real-scene information collected includes information specific to the area under the viaduct, it means that the vehicle is traveling on a road under the viaduct, and it can be determined that the first viaduct positioning result of the vehicle is under the viaduct.

[0107] If the first real-scene information collected includes information specific to the viaduct, it means that the vehicle is traveling on a road on the viaduct, and it can be determined that the first viaduct positioning result of the vehicle is on the viaduct.

[0108] It can be seen that through the above method, the accurate determination of the first elevated positioning result can be achieved, thereby improving the accuracy of the speeding electronic eye's prompts, and further improving the accuracy of the navigation display.

[0109] It should be noted that the various optional implementation modes introduced in the embodiments of the present application can be implemented in combination with each other or separately if they do not conflict with each other, and the embodiments of the present application are not limited to this.

[0110] For ease of understanding, a specific embodiment is used as an example for illustration:

[0111] like Figure 3 As shown, the navigation display method of the embodiment of the present application may include the following contents:

[0112] 1. The speeding electronic eye information attributes output by the navigation system are expanded to 3, and a new attribute of whether it is on an elevated road is added, that is, the elevated positioning result.

[0113] 2. Based on the visual information from the front-view camera, such as traffic lights, isolation belts, intersections, crosswalks, non-motor vehicle targets, on- and off-ramps, road speed limits, and special road signs (such as Stop and Give Way, Watch Out for Children, etc.), the assisted and automated driving control unit (ADASDomain Controller Unit, ADCU) can determine whether the vehicle is on an overpass, that is, the first overpass positioning result mentioned above.

[0114] 3. If the ADCU determines that the attribute of whether the vehicle is on an elevated road output by the navigation system is consistent with the judgment based on the visual information, the speed limit information and speeding camera information of the speeding electronic eye will continue to be transparently transmitted. If the ADCU determines that the attribute of whether the vehicle is on an elevated road output by the navigation system is inconsistent with the judgment based on the visual information, the transmission of any information of the speeding electronic eye will be stopped.

[0115] 4. The navigation system receives the status of whether the vehicle is on an elevated bridge based on the visual information determined by ADCU, searches for speeding electronic eyes based on this status, and outputs their information.

[0116] The navigation display method of the embodiment of the present application introduces visual information to assist in determining whether the vehicle is on an elevated road. If the navigation system and vision are inconsistent regarding this attribute, the navigation system quickly corrects it and re-outputs the speeding electronic eye information on the corresponding road. In this way, the accuracy of the speeding electronic eye prompts can be improved, thereby improving the accuracy of the navigation display.
