The server 130 receives the road side sensing information reported by the road side base station 120 in real time, and provides data required for interface display for the vehicle end intelligent device 110 based on the road side sensing information under the condition that the vehicle end intelligent device 110 is required. In some embodiments, server 130 may be other intelligent roadside devices.

As an example, the vehicle-end smart device 110 may also report its own positioning information and vehicle description information to the server 130 in real time. In this case, as shown in fig. 2, the server 130 not only receives the roadside sensing information reported by the roadside base station 120 in real time, but also receives the positioning information and the vehicle description information reported by the vehicle-end intelligent device 110 in real time. The server 130 matches the vehicle from the roadside sensing information based on the positioning information and the vehicle description information, and reports a matching result to the vehicle-end intelligent device 110, so that the vehicle-end intelligent device 110 highlights the vehicle under the condition that it is determined that the vehicle is located within the sensing range of the roadside base station 120 according to the matching result, and specific implementation thereof may refer to the embodiments described below. For the vehicle-end intelligent device 110, information such as the speed and the heading angle of the vehicle CAN be acquired from a central control system of the vehicle through a CAN interface.

In an embodiment, the server 130 may be one server, or may also be a server cluster composed of multiple servers, which is not limited in this embodiment of the present application. In an embodiment, the server 130 may be an information service providing end disposed at a roadside (for example, the form of the information service providing end may be a unit integrated into a roadside base station), or an information service providing end disposed at an edge node, or an information service providing end disposed at a cloud end, which is not limited in this embodiment of the present application.

It should be noted that, in the embodiment of the present application, data communication between the vehicle-end intelligent device 110 and the roadside base station 120 is implemented by the server 130 as an example. In another embodiment, the vehicle-end intelligent device 110 may also directly perform data communication with the roadside base station 120, which is not limited in this embodiment of the application.

After the system architecture provided in the embodiment of the present application is introduced, taking the vehicle-end intelligent device 110 as a terminal device as an example, the method for displaying data provided in the embodiment of the present application is described in detail with reference to the accompanying drawings.

Example one

Step A1: and in the process of displaying the first interactive interface of the high-precision map, when the over-the-horizon visual angle display condition is triggered, displaying the over-the-horizon interactive interface.

The high-precision map refers to a map defined in a high-precision and fine manner. The high-precision map can accurately depict how many lanes are on a road and the details of the shape of the road, and can truly reflect the actual pattern of the road, such as which places are widened or narrowed.

Generally, an area corresponds to a high-precision map, a high-precision map corresponds to a file package, and a file package corresponds to a three-dimensional scene, wherein the three-dimensional scene comprises at least one three-dimensional model.

As an example of the application, the terminal device displays a first interactive interface of the high-precision map by specifying the APP. In implementation, a first interactive interface of the APP for displaying the high-precision map based on the file package is specified, specifically, an object in an area is generated into a three-dimensional model based on the file package through a WebGI/OpenGI technology, and a three-dimensional scene is formed by splicing the original coordinates and the original size of the object, so that the display of the high-precision map is realized. Objects may include, but are not limited to, trees, vehicles, light poles, roads, buildings, among others.

During the process of displaying the first interactive interface of the high-precision map, when the condition that the over-viewing angle display is triggered is detected, the fact that the user probably wants to display the over-viewing mode is explained. Under the condition, the terminal equipment acquires road side sensing information sensed by the target road side base station, and displays the beyond-the-horizon interactive interface based on the road side sensing information.

Wherein, beyond visual range visual angle display condition can set up according to actual demand. According to different triggering modes of beyond visual range angle display conditions, the definition of the first interactive interface is different, and the determination mode of the target road-side base station is also different, which may specifically include but is not limited to the following several conditions:

in the first case: and under the condition that the first interactive interface is a driving mode interactive interface, triggering the over-the-horizon viewing angle display condition if the vehicle is determined to enter the perception range of the first road side base station according to the current positioning information of the vehicle. The driving mode interactive interface is a driving visual angle of a lane level of the vehicle, the driving visual angle is switched in real time along with positioning information of the vehicle, the first road side base station is a road side base station in the high-precision map, and the target road side base station is the first road side base station.

In one embodiment, the driving mode interaction interface is shown in FIG. 3. And in the process of displaying the driving mode interactive interface of the high-precision map by the terminal equipment, determining whether the vehicle currently drives into the sensing range of the first road side base station or not according to the positioning information of the vehicle and the high-precision map. For example, when the actual distance between the current position of the vehicle and the first roadside base station is determined to be smaller than the distance threshold value according to the positioning information and the high-precision map of the vehicle, the vehicle is determined to enter the perception range of the first roadside base station. Under the condition that the vehicle enters the sensing range of the first road side base station, the beyond-visual-distance viewing angle can be checked according to the road side sensing information sensed by the first road side base station, so that under the condition, the display condition of the beyond-visual-distance viewing angle is triggered and met. At this time, the first roadside base station into which the vehicle enters is taken as the target roadside base station.

The distance threshold may be set by a user according to actual needs, or may also be set by a default of the terminal device, for example, the distance threshold may be 200 meters, which is not limited in this embodiment of the application.

In the second case: and in response to the beyond-visual-distance trigger operation input through the beyond-visual-distance icon in the first interactive interface, at least one intersection option is displayed in the first interactive interface in a superposed mode, and the at least one intersection option is used for selecting the intersection. And triggering an beyond-the-horizon viewing angle display condition in response to intersection selection operation input through at least one intersection option, wherein the target road side base station is a road side base station arranged at the selected intersection.

In this case, the first interactive interface is the initial interactive interface after entering the high-precision map. When the vehicle enters the terminal device initially, the terminal device adjusts the view angle parameter of the scene camera, so that the area scene from the view angle of the extended scene camera (such as a WebGI/OpenGI view angle component) to the radius of the extended scene camera within the range of the preset distance threshold from the vehicle is overlooked by taking the position of the vehicle as the center and the upper and lower sides of the screen as the reference. Illustratively, the initial interaction interface after the terminal device enters the high-precision map is as shown in (a) of fig. 4, that is, when the terminal device enters the high-precision map initially, a certain area is displayed at a long distance from a bird's eye view. The preset distance threshold may be set according to actual requirements, for example, the preset distance threshold is 1 km.

Continuing with FIG. 4 (a), in one embodiment, an over-the-horizon icon is included in the initial interactive interface. When the triggering operation of the over-the-horizon icon by the user is detected, the fact that the user wants to switch to the over-the-horizon mode is indicated. In response to the triggering operation of the over-the-horizon icon by the user, the terminal device sends an intersection information acquisition request to the server based on the positioning information of the vehicle, so that the server acquires and feeds back intersection information near the position where the vehicle is located, and thus, the terminal device displays at least one intersection option based on the acquired intersection information, and the display effect is as shown in (b) in fig. 4. As an example, the intersection information acquisition request may be an http (HyperText Transfer Protocol) request.

In one embodiment, in the case that the current vehicle is located within the sensing range of the target road-side base station, the at least one intersection option is arranged in the order of the distance between the corresponding intersection and the position of the vehicle from the near to the far. Because the intersection which is closer to the user can be selected for viewing with high probability, the intersection can be conveniently and quickly selected by the user after sequencing, and the user experience is improved.

In another embodiment, when the vehicle is located outside the coverage area of the high-precision map, the intersection information in the intersection information list may be arranged randomly or according to a certain preset strategy, and the preset strategy may be set according to actual requirements, which is not limited in the embodiment of the present application.

After the terminal equipment displays at least one intersection option, a user can select an over-the-horizon viewing angle of which intersection is required to be viewed from the at least one intersection option according to actual requirements. When a user selects an intersection from at least one intersection option, the terminal device triggers an beyond-the-horizon viewing angle display condition in response to a selection operation of the user on the intersection. And the terminal equipment determines the road side base station set at the intersection selected by the user according to the high-precision map, and takes the determined road side base station as a target road side base station.

In the third case: and triggering the over-the-horizon viewing angle display condition in response to over-the-horizon triggering operation input through an over-the-horizon icon in the first interactive interface, wherein the target road side base station is a road side base station which is determined to be closest to the vehicle based on the positioning information of the current vehicle.

In this case, the first interactive interface is the initial interactive interface after entering the high-precision map. In one embodiment, the over-the-horizon icon is included in the initial interactive interface, and when the triggering operation of the over-the-horizon icon by the user is detected, the fact that the user may want to enter the over-the-horizon mode is indicated, and therefore the terminal device triggers the over-the-horizon viewing angle display condition. And the terminal equipment determines the road side base station closest to the current position of the vehicle as the target road side base station. That is, in this case, the terminal device does not present at least one intersection option, but defaults to the user viewing the over-the-horizon viewing angle of the intersection closest to the vehicle.

In a fourth case: and triggering the beyond-visual-range viewing angle display condition in response to site selection operation input through a site identifier in the first interactive interface, wherein the site identifier is used for marking the corresponding road side base station, and the target road side base station is the road side base station corresponding to the site identifier.

In this case, the first interactive interface is the initial interactive interface after entering the high-precision map. In one embodiment, after the terminal device displays the initial interactive interface, the location of the roadside base station may be marked with the site identifier prominence in the initial interactive interface, for example, as shown in fig. 4 (a) at 41, the site identifier is marked with a circular ring. When the triggering operation of the user on the site identification is detected, it is indicated that the user may want to enter the beyond-the-horizon viewing angle of the road side base station corresponding to the site identification, so that the terminal device triggers the beyond-the-horizon viewing angle display condition at this time. And the road side base station corresponding to the station mark selected by the user is used as the target road side base station.

And under the condition that the beyond visual range visual angle display condition is triggered, the terminal equipment acquires road side sensing information sensed by the target road side base station, and displays an beyond visual range interaction interface according to the road side sensing information. Illustratively, the beyond visual range interactive interface comprises vehicles, pedestrians, buildings, driveways and trees of the target area.

As an example, the specific implementation of acquiring the roadside sensing information sensed by the target roadside base station may include: and establishing a designated connection between the terminal equipment and the server, and acquiring roadside sensing information reported to the server by the target roadside base station in real time from the server through the designated connection. Wherein, appointed connection can set up according to actual need, exemplarily, appointed connection can refer to socket and connect.

Therefore, after the terminal equipment acquires the road side sensing information sensed by the target road side base station from the server in real time, the beyond-the-horizon interactive interface is displayed according to the road side sensing information, and the traffic participants in the beyond-the-horizon interactive interface change and display in real time along with the updating of the road side sensing information.

As an example of the application, in the case that the current vehicle is located in the perception range of the target road-side base station, the vehicle is highlighted in a preset display mode in the beyond visual range interactive interface. The preset display mode can be set according to actual requirements, for example, a more striking color display mode can be adopted, or a flashing display mode can be adopted. Therefore, the user can quickly know the position of the vehicle in which the user is located in the beyond-the-horizon interactive interface.

In one embodiment, the number of the traffic participating objects sensed by the target road-side base station is multiple, and road-side sensing information of each traffic participating object comprises positioning information and traffic participating object description information. In this case, the terminal device obtains the positioning information and the vehicle description information of the vehicle, and determines target roadside sensing information matched with the vehicle from the plurality of roadside sensing information according to the positioning information and the vehicle description information of the vehicle, wherein the target roadside sensing information is used for highlighting the vehicle in a preset display mode in the beyond-sight interaction interface.

For example, the terminal device determines at least one piece of roadside sensing information including the positioning information from a plurality of pieces of roadside sensing information according to the positioning information of the vehicle, and then determines the roadside sensing information including the vehicle description information of the vehicle from the determined at least one piece of roadside sensing information to obtain the target roadside sensing information. And the terminal equipment determines a display position according to the target roadside perception information and highlights the vehicle in the beyond visual range interactive interface in a preset display mode based on the display position.

It should be noted that, the above description is made by taking an example in which the matching process is executed by the terminal device. In another embodiment, the matching process may also be performed by a server, for example, the terminal device reports its positioning information and vehicle description information to the server in real time, and the server matches the target roadside sensing information of the vehicle from the roadside sensing information reported by the target roadside base station in real time according to the positioning information and the vehicle description information, and marks the target roadside sensing information. And the server sends the marked roadside sensing information to the terminal equipment, so that the vehicle corresponding to the marked roadside sensing information is highlighted when the beyond-the-horizon interaction interface is displayed by the terminal equipment. The matching process is executed by the server, so that the operation power consumption of the terminal equipment can be reduced.

In one embodiment, in the process of displaying the beyond-the-horizon interactive interface, the terminal device overlooks and stretches the view angle of the scene camera to the map scene with the display center point ranging from 400m to 500m by taking the intersection where the target roadside base station is located as the center, so as to obtain the beyond-the-horizon interactive interface. In the appointed APP interface, the visual angle is fixed, the intersection where the vehicle is located when the interface is cut in is used as the intersection below the interface to be displayed, the traffic running state information of each intersection and the roadside base station mark after the roadside sensing result of the station base station is loaded can be clearly displayed, and the display effect of the beyond-the-horizon interactive interface is exemplarily shown in fig. 5.

In one embodiment, when the over-the-horizon interactive interface enters under the first condition, if it is determined that the vehicle leaves the sensing range of the target roadside base station according to the positioning information of the vehicle (for example, when the vehicle is within 200 to 230 meters from the intersection stop line), the display of the over-the-horizon interactive interface is exited, and the interface returns to the driving mode interactive interface.

In one embodiment, when the beyond-the-horizon interactive interface is quitted from displaying, the terminal device closes the designated connection (such as socket connection) with the server, namely, stops acquiring the roadside sensing information from the server in real time, and empties vehicles, pedestrian models and the like generated according to the roadside sensing information.

In one embodiment, in the over-the-horizon mode, when the moving touch gesture of the user is detected, the over-the-horizon interactive interface is controlled to move along with the moving touch gesture of the user, and a return option is displayed in the moved over-the-horizon interactive interface, such as the moved over-the-horizon interactive interface shown in fig. 6, and the return option is shown as 61 in fig. 6. When the triggering operation of the user on the return option is detected, it indicates that the user wants to return to the display state before the movement, and at this time, the terminal device returns to the display state before the movement, that is, the display state shown in fig. 5. After recovery, the return options are no longer displayed.

In the beyond-the-horizon mode, when it is detected that the user triggers the beyond-the-horizon icon again, the terminal device exits the beyond-the-horizon mode and returns to the display state before entering the beyond-the-horizon mode, for example, the interactive interface is switched to the initial display state of the high-definition map, for example, the state shown in (a) in fig. 4 is returned.

As an example of the application, when the first interactive interface is an initial interactive interface of a high-precision map, before displaying the initial interactive interface, the terminal device may compare a coverage area corresponding to the high-precision map with an area threshold to display the initial interactive interface according to a comparison result. Illustratively, in the case that the coverage of the high-precision map is less than or equal to the area threshold, the entire coverage of the high-precision map is presented. And under the condition that the coverage area of the high-precision map is larger than the area threshold, if the current vehicle is positioned in the coverage area of the high-precision map, using the vehicle as a display center to display a partial map area of the high-precision map as an initial interactive interface, and if the vehicle is positioned out of the coverage area of the high-precision map, using a central point of the high-precision map as the display center to display the partial map area of the high-precision map as the initial interactive interface.

The region threshold may be set according to actual requirements, which is not limited in the embodiment of the present application.

That is, if the coverage area of the high-precision map is less than or equal to the area threshold, it is indicated that the coverage area of the high-precision map is small, and in this case, the entire coverage area can be displayed in a bird's eye view when the initial interactive interface is displayed. Otherwise, if the coverage area of the high-precision map is larger than the area threshold, the coverage area of the high-precision map is larger, and the whole coverage area of the high-precision map may not be completely displayed at this time. Therefore, the display mode of the high-precision map is adaptively adjusted according to the size of the coverage area of the high-precision map and the positioning information of the vehicle, and the display effect is improved.

It should be noted that, in the process of displaying the initial interactive interface, when detecting a gesture touch operation of the user, the terminal device synchronously adjusts the view angle of the scene camera. Wherein the gesture touch operation may include, but is not limited to, a two-finger zoom, a one-finger pan, and the like.

As an example of the present application, when the first interactive interface is an initial interactive interface of a high-precision map, in a case where a parking lot is included in a coverage area of the high-precision map, parking lot information of the parking lot is presented in the first interactive interface.

That is, the terminal device may query whether a parking lot exists in the coverage area of the high-precision map, for example, may send a parking space query request to the server, where the parking space query request may be an http request. And receiving a parking space inquiry response sent by the server, and determining that the parking lot exists when the parking space inquiry response carries the parking lot information. When the parking lot exists, the parking lot information is marked in the parking lot area in a first interactive interface of the high-precision map. For example, as shown in fig. 4, the parking lot information may include, but is not limited to, the number of empty slots and the total number of slots.

Further, the number of the vacant parking spaces can be displayed in a grading mode according to different residual vacant space conditions, wherein different display levels are used for indicating different vacant parking space allowance degrees. For example, when the number of the empty parking spaces is displayed as green, the empty parking spaces in the parking lot are sufficient; when the number of the empty parking spaces is yellow, the empty parking space allowance of the parking lot is insufficient; when the number of the empty parking spaces is displayed in red, the shortage of the empty parking space allowance of the parking lot is indicated. Therefore, the parking lot information is displayed in the first interactive interface of the high-precision map, so that a user can quickly know the condition of a nearby parking lot, a proper parking lot can be conveniently selected when the user needs to park, and the user experience is improved.

As an example, when a user's trigger operation on a displayed parking lot area is detected, indicating that the user may want to go to a parking lot corresponding to the parking lot area, in this case, a navigation path between the current position of the vehicle and the parking lot may be generated and displayed, so that the user can go to the selected parking lot according to the navigation path.

As another example, when a user's trigger operation on a displayed parking lot area is detected, before the navigation path is generated, a prompt message for prompting the user whether to go to a selected parking lot may also be presented, for example, the presented prompt message may be "go to the parking lot". When receiving the confirmation instruction, it indicates that the user wants to go to the parking lot, and at this time, a navigation path is generated, otherwise, when receiving the cancel instruction, it indicates that the user does not want to go to the parking lot, and at this time, the navigation path is not generated, and the display interface returns to the view shown in fig. 4 (a). Therefore, corresponding operation can be executed according to the actual requirement of the user, and the user experience is improved.

In an embodiment, please continue to refer to fig. 4, the first interactive interface includes a conventional map icon, when the user wants to switch to the conventional map, the user can click the conventional map icon, and in response to the user's triggering operation on the conventional map icon, the terminal device exits the high-precision map mode and returns to the display state of the conventional map, and the display state of the conventional map is refer to fig. 19.

In one embodiment, in the case that the first interactive interface is an initial interactive interface of a high-precision map, when it is detected that a user performs a zooming operation on the displayed first interactive interface, the terminal device performs perspective zooming to display road-lane-level high-precision map information through the control screen.

In the embodiment of the application, in the process of displaying the first interactive interface of the high-precision map, when the over-the-horizon view angle display condition is triggered, it is indicated that the user may wish to view the over-the-horizon view angle, and at this time, the over-the-horizon interactive interface is displayed. The over-the-horizon interactive interface displays roadside perception information of a target area at a bird's-eye view angle, the target area is determined based on the installation position and the perception range of a target roadside base station, and the roadside perception information comprises traffic participation object information perceived by the target roadside base station. That is, the over-the-horizon interactive interface displayed at the bird's-eye view shows the road condition information of the target area perceived by the target road side base station in detail, so that the user can quickly and intuitively know the road condition, and the driving assisting effect can be improved.

The data display method after the two pairs of terminal devices enter the beyond-the-horizon interactive interface is further described through the following embodiments.

Example two

In one embodiment, the beyond-the-horizon interactive interface comprises a traffic state information acquisition option, and in response to an information acquisition operation input through the traffic state information acquisition option, a traffic state information frame of the intersection where the target road side base station is located is loaded at a preset position in the beyond-the-horizon interactive interface, wherein the traffic state information frame comprises traffic state information of each intersection of the intersection where the target road side base station is located.

The preset position may be set by a user according to actual needs, or may be set by default by the terminal device, which is not limited in the embodiment of the present application.

Illustratively, the traffic status information may include, but is not limited to, intersection information, lane-level vehicle queue length, lane-level traffic information, roadside video information.

The intersection information may include an intersection name and/or an intersection direction, for example, the intersection name may include a tangjia green road, a post-factory village road, an a garden four road, and the like. The lane information may include a lane number, a lane drivable direction, and the like.

The lane-level traffic flow information is used for indicating the traffic flow of the lane section. The lane section flow refers to the number of vehicles passing through the stop line section of the lane within a preset time length. For example, the stop line cross section may be a zebra crossing cross section, wherein the preset time period may be set according to actual requirements, for example, the preset time period is 10min, and the traffic lane cross section flow is updated every 10 min.

As an example of the present application, the traffic status information acquisition option includes at least one of a vehicle queue information acquisition option, a traffic flow information acquisition option, and a roadside video option. Therefore, at least one of vehicle queuing, traffic flow and roadside videos can be conveniently checked by a user, so that the user can know detailed traffic states of roads, and favorable auxiliary driving is provided for the user.

As an example, when the beyond-the-horizon interactive interface includes a traffic flow information acquisition option, in response to a traffic flow information acquisition operation input through the traffic flow information acquisition option, a traffic state information frame of an intersection where the target roadside base station is located is displayed in a superimposed manner at a preset position in the beyond-the-horizon interactive interface, where the traffic state information frame includes lane-level traffic flow information of each intersection where the target roadside base station is located.

Wherein the lane-level traffic information may include traffic information of at least one lane.

Optionally, the traffic status information frame at this time may further include, but is not limited to, intersection information and lane directions of each intersection, and the intersection information may include an intersection direction and an intersection name.

In implementation, in response to a traffic flow information acquisition operation input through the traffic flow information acquisition option, the terminal device sends a traffic flow information acquisition request to the server, where the traffic flow information acquisition request carries intersection information. As an example, after receiving the traffic flow information acquisition request, the server acquires, according to a current time point, lane-level traffic flow information of an intersection indicated by the intersection information counted most recently from the time point, and sends the acquired lane-level traffic flow information to the terminal device for display.

In one embodiment, the lane-level traffic flow information is displayed in a grading manner based on a threshold range of lane section flow indicated by the lane-level traffic flow information, and different display levels are used for indicating different traffic flow period states, wherein the traffic flow period states comprise a flow peak period state, a flow middle peak period state and a flow low peak period state.

Wherein, the threshold range can be set according to actual requirements.

For example, when the lane section flow of the lane is greater than the first flow threshold, the lane section flow may be displayed in red to indicate that the lane is in a flow peak period state, when the lane section flow is between the second flow threshold and the first flow threshold, the lane section flow may be displayed in yellow to indicate that the lane is in a flow peak period state, and when the traffic flow is less than the second flow threshold, the lane section flow may be displayed in green to indicate that the lane is in a flow peak period state. Therefore, the lane-level traffic flow information is distinguished and displayed through different display levels, so that a user can conveniently and quickly know the lane section flow of each lane, and the user can quickly make a driving decision.

The first flow threshold and the second flow threshold can be set according to actual demands.

It should be noted that, the above description is only made by taking red, yellow and green as examples to respectively identify the traffic peak time period state, the traffic middle peak time period state and the traffic low peak time period state, in another embodiment, the identification may be distinguished by other colors, or may be distinguished by other manners (for example, different fonts), which is not limited in this application embodiment.

For example, referring to fig. 5, the traffic flow information obtaining option is a "traffic flow" option, and after the user clicks the "traffic flow" option, the terminal device displays the corresponding traffic status data in response to the user's triggering operation on the "traffic flow" option, and the display effect is as shown in fig. 7.

And when the user clicks the traffic flow information acquisition option again, the terminal equipment cancels the display of the traffic state information corresponding to the traffic flow information acquisition option in response to the triggering operation of the user on the traffic flow information acquisition option again.

As another example, when the beyond-the-horizon interactive interface includes a vehicle queuing information acquisition option, in response to a vehicle queuing information acquisition operation input through the vehicle queuing information acquisition option, a traffic state information frame of an intersection where the target roadside base station is located is displayed superimposed at a preset position in the beyond-the-horizon interactive interface, the traffic state information frame including lane-level vehicle queuing information of each intersection of the intersection where the target roadside base station is located.

In implementation, in response to a vehicle queuing information acquisition operation input through the vehicle queuing information acquisition option, the terminal device sends a vehicle queuing information acquisition request to the server, wherein the vehicle queuing information acquisition request carries intersection information, so that the server feeds back the vehicle queuing information of an intersection indicated by the intersection information.

Optionally, the lane-level vehicle queuing information is displayed in a hierarchy based on a threshold range in which the vehicle queuing length indicated by the lane-level vehicle queuing information is located, and different display levels are used for indicating different lane congestion degrees.

Optionally, when the vehicle queue length of the lane is greater than the first length threshold, the vehicle queue length may be displayed in red, indicating that the lane is in a heavily congested state; when the vehicle queue length is between the second length threshold and the first length threshold, the vehicle queue length may be displayed in yellow to indicate that the lane is in a light congestion state, and when the vehicle queue length is less than the second length threshold, the vehicle queue length may be displayed in green to indicate that the lane is in a non-congestion state. Therefore, the lane-level vehicle queuing information is distinguished and displayed through different display levels, so that a user can conveniently and quickly know the vehicle queuing conditions of all lanes, and the user can quickly make a driving decision.

Wherein, first length threshold value and second length threshold value all can set up according to actual demand.

It should be noted that, the above description is only given by taking red, yellow and green as examples to identify the severe congestion status, the light congestion status and the non-congestion status respectively, and in another embodiment, the identification may be distinguished by other colors, or may be distinguished by other manners (for example, different fonts), which is not limited in the embodiment of the present application.

For example, referring to fig. 5, the vehicle queuing information obtaining option is a "vehicle queuing" option, and after the user clicks the "vehicle queuing" option, in response to the user's triggering operation on the "vehicle queuing" option, the terminal device displays the traffic status data corresponding to the vehicle queuing information obtaining option, and the display effect is as shown in fig. 8.

And when the user clicks the vehicle queuing information acquisition option again, the terminal equipment cancels the display of the traffic state information corresponding to the vehicle queuing information acquisition option in response to the triggering operation of the user on the vehicle queuing information acquisition option again.

As another example, when the over-the-horizon interactive interface includes a roadside video option, in response to a roadside video acquisition operation input through the roadside video option, a traffic status information frame of an intersection where the target roadside base station is located is displayed superimposed at a preset position in the over-the-horizon interactive interface, where the traffic status information frame includes a video equipment icon of at least one intersection of the intersection where the target roadside base station is located.

In an implementation, the roadside video option may be clicked when the user wants to view the surveillance video of the selected intersection. After clicking the road side video option, the user responds to road side video acquisition operation input through the road side video option, the terminal equipment inquires which intersection or intersections where the target road side base station is located have the video equipment from the server, and in the traffic state information frame, the video equipment icon is displayed at the position corresponding to the intersection where the video equipment exists. For example, the display effect is as shown in fig. 9.

Optionally, in response to a video device selection operation input through the video device icon of at least one intersection, playing the video stream captured by the selected video device at a preset position in the beyond-the-horizon interactive interface.

After the video equipment icon of at least one intersection is displayed in the beyond-the-horizon interactive interface, when a user wants to view real-time videos of a certain intersection, the video equipment icon of the intersection can be triggered, in response to the triggering operation of the user on the video equipment icon, the terminal equipment acquires a road side video stream address corresponding to the video equipment icon, acquires video stream data based on the road side video stream address, and then plays the video stream data in the beyond-the-horizon interactive interface by using a video playing plug-in, for example, the display effect is as shown in fig. 10.

The video stream address may be in rtsp format, rtmp format, hls format, or the like.

In implementation, in response to a triggering operation of a user on a video device icon, the terminal device sends a video address acquisition request to the server, and optionally, intersection information is carried in the video address acquisition request, so that the server returns a roadside video stream address corresponding to the intersection information. The video address obtaining request may be an http request.

When the user clicks the played video picture, in response to the triggering operation of the user on the played video picture, the terminal device closes the video picture, the interface is restored to be a traffic state information frame which displays the intersection where the target road side base station is located at the preset position in the beyond visual range interaction interface in an overlapping mode, and the traffic state information frame comprises video device icons of at least one intersection of the intersection where the target road side base station is located. If the user wants to continue to view the real-time videos of other intersections, the user can continue to click other video device icons based on the recovered interface.

When the user clicks the roadside video option again, in response to the triggering operation of the user on the roadside video option again, the terminal device closes the played monitoring video, cancels the display of the information frame, namely cancels the display of the intersection information and the video device icons of the intersections, and restores the display state to that shown in fig. 5.

Optionally, in the process of playing the video stream, displaying first prompt information in the beyond-visual-range interactive interface, where the first prompt information is used to prompt that the user does not watch the video for a long time, and pay attention to driving safety. Therefore, the driver can be timely reminded of driving safely, and safety accidents are avoided.

In the embodiment of the application, the real-time traffic state information in the beyond-the-horizon mode is displayed for the user, so that the user can make driving decisions according to the real-time traffic state information, such as selection of non-congestion road sections for driving and the like, and a better driving assistance effect is provided for the user.

In one embodiment, the first interactive interface of the high-precision map further comprises a driving mode icon in addition to the over-the-horizon icon. For example, as shown in fig. 4, the driving mode icon and the over-the-horizon icon may be displayed in an upper left area of the first interactive interface. The user can enter a driving mode or an over-the-horizon mode according to actual requirements. The interaction between the driving mode icon and the over-the-horizon icon is mutually exclusive, namely when a user clicks one of the options, the display interface only displays the interaction information corresponding to the option clicked by the user, and the option not clicked is recovered to be in an unselected state. Next, data display in the driving mode will be described by the following third embodiment.

EXAMPLE III

As an example of the present application, when it is determined that the vehicle is located within the coverage area of the high-precision map according to the positioning information of the vehicle, the terminal device controls the driving mode icon in the first interactive interface to be in a triggerable state while marking the vehicle in the first interactive interface of the high-precision map, as shown in (a) diagram in fig. 11; when the vehicle is determined to be out of the coverage range of the high-precision map according to the positioning information of the vehicle, the terminal device controls the driving mode icon in the first interactive interface to be in the non-triggerable state, as shown in the (b) diagram in fig. 11.

As an example of the present application, in response to a driving mode triggering operation input through a driving mode icon in the first interactive interface, the terminal device switches the interface from the first interactive interface to the driving mode interactive interface. The driving mode interactive interface is a driving visual angle of a lane level of the vehicle, and the driving visual angle is switched in real time along with the positioning information of the vehicle.

That is, after entering the first interactive interface of the high-precision map, the driving mode icon may be clicked when the user wants to view the driving view angle under the condition that the driving mode icon is in a triggerable state. In response to the triggering operation of the driving mode icon by the user, the driving mode icon remains in the selected state, and the terminal device switches from the first interactive interface to the driving view angle at the lane level, that is, enters the driving mode interactive interface, for example, the display effect is as shown in fig. 13. In the implementation process, the terminal device acquires the positioning information and the direction information of the vehicle and calls the WebGI/OpenGI SDK to update the position and the direction of the vehicle in the three-dimensional scene. Therefore, the user can clearly view the detailed road condition of the current road of the vehicle, and the driver is assisted to drive safely.

When the user wants to return to the display interface at the bird's-eye view angle, the user can click the driving mode icon again. When the terminal device detects the triggering operation on the driving mode icon again, the first interactive interface is switched from the driving mode interactive interface back to the bird's-eye view angle, that is, the display interface shown in fig. 11 (a) is restored, at this time, the driving mode is exited, and the driving mode icon is restored to the unselected state.

In one embodiment, under a driving mode interactive interface of a driving view angle, when a picture moving operation of a user on a display screen is detected, the picture view angle is moved along with the picture moving operation of the user, that is, the terminal device controls the view angle of a scene camera to be adjusted according to the picture moving operation, and stops the real-time switching operation of the positioning information of a following vehicle. Referring to fig. 12, a return option 121 is provided in the display interface after the frame view angle is moved. When the user wants to restore to the driving mode interactive interface before movement, the return option 121 may be triggered, and in response to the triggering operation of the user on the return option 121, the terminal device controls the scene camera to restore to automatically follow the oblique rear of the current vehicle, that is, the terminal device switches back to the driving mode interactive interface before movement, and at this time, the return option is not displayed.

As another example of the present application, the driving mode interactive interface includes at least one of a vehicle queuing information obtaining option, a traffic flow information obtaining option, and a road side video option. And when the triggering operation of any one option in the at least one option is detected, acquiring the traffic state information corresponding to the triggered option, and displaying the traffic state information in the driving mode interactive interface. The traffic state information at this time is sensed by the roadside base station closest to the vehicle, that is, the target roadside base station at this time is the roadside base station closest to the vehicle determined based on the positioning information of the vehicle.

In implementation, the terminal device may send a traffic state information acquisition request to the server, where the traffic state information acquisition request may carry an intersection identifier of an intersection where the target roadside base station is located, so that the server returns corresponding traffic state information. The traffic state information acquisition request may be, for example, an http request.

In one example, when the driving mode interactive interface includes the traffic flow information acquisition option, in response to a traffic flow information acquisition operation input through the traffic flow information acquisition option, a traffic state information frame of an intersection where the target roadside base station is located is displayed in a superimposed manner at a preset position of the driving mode interactive interface, where the traffic state information frame includes lane-level traffic flow information levels of respective intersections where the target roadside base station is located.

The implementation principle of the method, the following display of the vehicle queuing information and the roadside video can be referred to the above display of the traffic state information under the over-the-horizon interactive interface, and repeated description is omitted here.

Wherein, the threshold value range can be set according to actual requirements.

For example, when the lane section flow of the lane is greater than the first flow threshold, the lane section flow may be displayed in red to indicate that the lane is in a flow peak period state, when the lane section flow is between the second flow threshold and the first flow threshold, the lane section flow may be displayed in yellow to indicate that the lane is in a flow peak period state, and when the traffic flow is less than the second flow threshold, the lane section flow may be displayed in green to indicate that the lane is in a flow peak period state.

It should be noted that, the above description is only given by taking red, yellow and green as examples to respectively identify the traffic peak time period state, the traffic middle peak time period state and the traffic low peak time period state, in another embodiment, the traffic peak time period state, the traffic middle peak time period state and the traffic low peak time period state may be identified by other colors, or may be identified by other manners (for example, different fonts), which is not limited in this embodiment of the application.

For example, referring to fig. 13, the traffic flow information obtaining option is a "traffic flow" option, and after the user clicks the "traffic flow" option, the terminal device displays the corresponding traffic status data in response to the user's triggering operation on the "traffic flow" option, and the display effect is as shown in fig. 14.

In another example, when the driving mode interactive interface includes a vehicle queuing information acquisition option, in response to a vehicle queuing information acquisition operation input through the vehicle queuing information acquisition option, a traffic state information frame of an intersection where the target roadside base station is located is displayed in a superimposed manner at a preset position of the driving mode interactive interface, where the traffic state information frame includes lane-level vehicle queuing information levels of respective intersections of the intersection where the target roadside base station is located.

Alternatively, when the vehicle queue length of the lane is greater than the first length threshold, the vehicle queue length may be displayed in red, indicating that the lane is in a heavily congested state; when the vehicle queue length is between the second length threshold and the first length threshold, the vehicle queue length may be displayed in yellow to indicate that the lane is in a light congestion state, and when the vehicle queue length is less than the second length threshold, the vehicle queue length may be displayed in green to indicate that the lane is in a non-congestion state.

For example, referring to fig. 13, the vehicle queuing information obtaining option is a "vehicle queuing" option, and after the user clicks the "vehicle queuing" option, in response to the user's trigger operation on the "vehicle queuing" option, the terminal device displays the traffic status data corresponding to the vehicle queuing information obtaining option, and the display effect is as shown in fig. 15.

In another example, when the driving mode interactive interface includes a roadside video option, a traffic state information frame of an intersection where the target roadside base station is located is displayed in an overlaid manner at a preset position in the driving mode interactive interface through roadside video acquisition operation input by the roadside video option, and the traffic state information frame includes video equipment icons of at least one intersection of the intersection where the target roadside base station is located.

For example, referring to fig. 13, the roadside video option may be clicked when the user wants to view the surveillance video of the selected intersection. After clicking the road side video option, the user responds to road side video acquisition operation input through the road side video option, the terminal equipment inquires which intersection or intersections where the target road side base station is located have the video equipment from the server, and in the traffic state information frame, the video equipment icon is displayed at the position corresponding to the intersection where the video equipment exists. For example, the display effect is as shown in fig. 16.

Optionally, in response to a video device selection operation input through the video device icon of the at least one intersection, playing the video stream captured by the selected video device at a preset position in the driving mode interactive interface.

After the video device icon of at least one intersection is displayed in the driving mode interactive interface, when a user wants to view a real-time video of a certain intersection, the video device icon of the intersection can be triggered, in response to the triggering operation of the user on the video device icon, the terminal device obtains a road side video stream address corresponding to the video device icon, obtains video stream data based on the road side video stream address, and then plays the video stream data in the driving mode interactive interface by using the video playing plug-in, for example, the display effect is as shown in fig. 17.

When the user clicks the roadside video option again, in response to the triggering operation of the user on the roadside video option again, the terminal device closes the played monitoring video, cancels the display of the information frame, that is, cancels the display of the intersection information and the video device icons at each intersection, and restores the display state to that shown in fig. 13.

Optionally, in the process of playing the video stream, displaying first prompt information in the driving mode interactive interface, where the first prompt information is used to prompt that the user does not watch the video for a long time, and pay attention to driving safety. Therefore, the driver can be timely reminded of driving safely, and safety accidents are avoided.

As an example of the present application, the driving mode interface further includes at least one intersection option, and the at least one intersection option is used to select an intersection. At this time, in a case where an intersection selection operation is detected based on at least one intersection option, in response to an information acquisition operation input through a traffic state information acquisition option in a driving mode interactive interface, a traffic state information frame of an intersection where a selected roadside base station is located is superimposed and displayed at a preset position in the driving mode interactive interface, the traffic state information frame including traffic state information of each intersection of the intersection.

Referring to fig. 13, after entering the driving mode interactive interface, the driving mode interactive interface is provided with a "vehicle queuing" option, a "traffic flow" option, a "roadside video" option, and a "nearby intersection" option. The "nearby intersection" option may be clicked when the user wants to see the traffic status information of a certain nearby intersection, and the terminal device presents at least one intersection option in response to the user's trigger operation on the "nearby intersection" option. Optionally, the at least one intersection option is arranged in order of a distance between the corresponding intersection and the location of the vehicle from near to far. The user can thus select an intersection desired to view based on at least one intersection option.

After a user selects a certain intersection through at least one intersection, when the user wants to check the traffic state information of the selected intersection, the user can trigger the traffic state information acquisition option. And responding to the triggering operation of the user on the traffic state information acquisition option, and acquiring and displaying corresponding traffic state information by the terminal equipment. The traffic state information acquisition option includes at least one of a traffic flow information acquisition option, a vehicle queuing information acquisition option, and a roadside video option, and specific implementation can be referred to above, and is not repeated here.

It should be noted that the above-mentioned vehicle queuing information acquisition option, traffic flow information acquisition option, and roadside video option are mutually exclusive, that is, when a user selects one of the options, only the interactive information corresponding to the selected option is displayed in the display interface, the other two unselected interactive information automatically disappear, and the two unselected options recover to the unselected state.

It should be noted that, the above description is made by taking an example of providing at least one intersection option in the driving mode interactive interface. In another embodiment, at least one intersection option may not be provided in the driving mode interface, in which case traffic status information for an intersection near the vehicle may also be viewed in other ways. For example, when the user's trigger operation on the traffic status information acquisition option is detected, the terminal device displays at least one intersection option in the driving mode interactive interface in an overlapping manner, for example, as shown in fig. 18, the terminal device displays a menu board, and displays at least one intersection option in the menu board. Therefore, the user can select which intersection the traffic state information is wanted to be checked according to actual requirements. In response to a selection operation input by a user through at least one intersection option, the terminal device obtains the traffic state information of the selected intersection, and displays the traffic state information in a mode of a traffic state information frame, and specific display principles and effects can be referred to above. In addition, when at least one intersection option is displayed in a superimposed manner, the terminal device cancels the display of at least the option given to the intersection when detecting that the user clicks any position of the interface gray area (non-menu board area), that is, the menu board disappears. The traffic state information acquisition option comprises at least one of a vehicle queuing information acquisition option, a traffic flow information acquisition option and a road side video option.

In the embodiment of the application, in the driving mode, the real-time traffic state information is displayed for the user, so that the user can make driving decisions according to the real-time traffic state information, such as selection of non-congestion road sections for driving and the like, and a better driving assistance effect is provided for the user.

Example four

Next, the data display process before entering the initial interactive interface of the high-precision map will be described.

B1: and displaying an interactive interface of the traditional map, wherein the interactive interface of the traditional map comprises high-precision map icons.

The traditional map refers to an application developed by a third party and can provide a basic navigation function for a driver.

In one embodiment, when a user wants to use assisted driving by means of a terminal device, the user may click on a designated APP in the terminal device, wherein the user may be a driver or a passenger. And responding to the triggering operation of the user on the appointed APP, and starting the appointed APP by the terminal equipment.

By way of example and not limitation, a conventional map is displayed by default after the APP is specified to be started, positioning information of the vehicle is obtained, and the vehicle is marked in a display interface of the conventional map based on the positioning information. In addition, high-precision map icons are displayed at preset positions in the display interface of the conventional map. The preset position can be set according to actual requirements, and exemplarily, the preset position can be an area in the upper right corner of a display interface of a traditional map.

Optionally, if the high-precision map is downloaded locally on the terminal device, and it is determined that the vehicle is located within the coverage area of the downloaded high-precision map based on the positioning information of the vehicle, the high-precision map icon may be displayed in a first preset manner, otherwise, if it is determined that the vehicle is not located within the coverage area of the downloaded high-precision map based on the positioning information of the vehicle, the high-precision map icon may be displayed in a second preset manner. The first preset mode and the second preset mode can be set according to actual requirements, and the second preset mode is different from the first preset mode, for example, the first preset mode and the second preset mode can indicate that different colors are adopted for displaying.

For example, referring to fig. 19, if the vehicle is not located within the coverage area of the high-precision map, the high-precision map icon in the interactive interface of the conventional map is displayed as shown in (a) of fig. 19; otherwise, if the vehicle is located within the coverage of the high-precision map, the high-precision map icon in the interactive interface of the conventional map is displayed as shown in (b) of fig. 19. Therefore, the high-precision map icons are displayed in different modes, so that a user can quickly and intuitively know whether the vehicle is currently located in the coverage range of the high-precision map in the terminal equipment.

B2: and responding to the triggering operation of the high-precision map icon, and displaying a second interactive interface, wherein the second interactive interface comprises an area list, and the area list comprises at least one area selection information.

In one embodiment, in the case that the user clicks the high-precision map icon, in response to the triggering operation of the user on the high-precision map icon, the terminal device sends an area query request to the server so that the server returns at least one area selection information of the high-precision map, and further, the server also returns the file package information of each area. Thus, the terminal device can acquire at least one area selection information. Wherein the package information may include a size of the package.

The terminal device displays a menu board in a first interactive interface of the conventional map in an overlapping manner, as shown in (a) or (b) of fig. 20, and displays at least one piece of region selection information in the menu board in an overlapping manner, thereby obtaining a second interactive interface. That is, the second interactive interface includes at least one piece of area selection information, the at least one piece of area selection information is used for the user to select an area, and each area indicated by the area selection information corresponds to the coverage area of one high-precision map. As an example and not by way of limitation, the region selection information may be a region name.

Referring to fig. 20, as an example and not by way of limitation, if a high-precision map corresponding to an area indicated by certain area selection information locally exists in the terminal device, the area where the area selection information is located may be displayed in a first color, and if a high-precision map corresponding to an area indicated by the certain area selection information locally does not exist in the terminal device, the area where the area selection information is located may be displayed in a second color. The first color and the second color can be set according to actual requirements, and the first color is different from the second color. The area selection information corresponding to the downloaded high-precision map and the area selection information corresponding to the non-downloaded high-precision map can be displayed in different colors in a distinguishing mode, so that a user can view the information visually, and user experience is improved.

In addition, the second interactive interface comprises two themes of a traditional map option and a composite map option. By default, as shown in fig. 20 (a), the conventional map option is in a selected state, that is, the interactive interface of the conventional map is displayed by default.

B3: and in response to a region selection trigger operation input through at least one region selection information, when a file package of the high-precision map exists, displaying a first interactive interface of the high-precision map based on the file package.

The file package includes area boundary range information of the high-precision map, original coordinates and original dimensions of the object, and the like, and the area boundary range information is used for indicating the boundary of the high-precision map and can be understood as being composed of polygonal points.

When the user wants to switch into a high-precision map, the area selection information in the area list may be clicked. And when the high-precision map corresponding to the area selection information selected by the user is downloaded to the local, the terminal equipment enters a first interactive interface of the high-precision map.

And when the file package of the high-precision map does not exist, displaying a downloading prompt window, wherein the downloading prompt window comprises second prompt information, and the second prompt information is used for prompting whether the high-precision map is downloaded. And downloading the file package of the high-precision map in response to the map downloading operation input through the downloading prompt window. And under the condition that the file package downloading of the high-precision map is completed, displaying a first interactive interface of the high-precision map based on the file package.

And when the high-precision map indicated by the area selection information selected by the user is not downloaded to the local, the terminal equipment displays second prompt information to prompt the user whether to download the high-precision map of the area. For example, referring to fig. 21, the second prompt message may be "determine to download the high-precision map of the current link", and in addition, a "cancel" option and a "confirm" option may be provided, and further, the size of the package of the high-precision map to be downloaded may be displayed. And when the triggering operation of the 'cancel' option is detected, the user does not need to download, the downloading operation is canceled at the moment, when the triggering operation of the 'confirm' option is detected, the user needs to download, and at the moment, the terminal equipment downloads the high-precision map corresponding to the area selection information selected by the user.

In implementation, the terminal device sends a map downloading request to the server in a downloading process, wherein the map downloading request carries an area identifier of an area to be downloaded. And the server receives the map downloading request and analyzes the map downloading request to obtain the area identifier. And then acquiring a file package of the high-precision map corresponding to the area identifier, and sending the acquired file package to the terminal equipment so that the terminal equipment downloads the high-precision map. Illustratively, the area identification may be an area ID or an area name.

In the above description, the second prompt information is sent to the user before downloading when the trigger operation of the user on the area selection information of the undeleted high-precision map is detected. In another embodiment, when the triggering operation of the user on the area selection information without downloading the high-precision map is detected, the corresponding high-precision map can be directly downloaded, that is, the second prompt information does not need to be sent to the user, so that the operation of the user can be reduced.

After the terminal equipment finishes downloading, the terminal equipment automatically decompresses and stores the decompressed data to the local, and exemplarily stores the decompressed data to a cache of a designated APP. As an example, after the terminal device completes downloading the high-precision map, the terminal device can directly enter the interactive interface of the high-precision map based on the downloaded file package.

As another example, after the terminal device completes downloading the high-precision map, the color of the area where the area selection information selected by the user is located may be changed from the second color to the first color, so that the user may determine whether to complete downloading according to the color, and thus when the user wants to enter the high-precision map, the user may click the area selection information, so that the terminal device enters the first interactive interface of the high-precision map.

It should be noted that, in the second interactive interface, each piece of area selection information downloaded with a high-precision map corresponds to a deletion option, when a user wants to delete a package of a high-precision map corresponding to a certain area, the deletion option corresponding to the area selection information of the area may be clicked, and in response to a trigger operation of the user on the deletion option corresponding to the area selection information, the terminal device deletes the package of the high-precision map corresponding to the area selection information, so as to save a local storage space.

Optionally, in response to a triggering operation of the user on a deletion option corresponding to the area selection information, the terminal device may further display deletion prompt information before deleting the package of the high-precision map corresponding to the area selection information, so as to prompt the user whether to confirm the deletion. And when a deletion confirmation instruction triggered by the user is received, the terminal equipment executes deletion operation again to avoid mistaken deletion.

In one embodiment, the second interactive interface comprises a composite map option, and in response to a triggering operation input through the composite map option, if the current vehicle is located in the coverage area of the high-precision map, the area of the high-precision map is displayed in an overlapping mode on the traditional map, and the vehicle is displayed in the area displayed in the overlapping mode based on the positioning information of the vehicle.

Referring to fig. 20 (b), if the user clicks the composite map option, in response to the user's trigger operation on the composite map option, the terminal device displays the high-precision map on the conventional map in an overlapping manner, and the display effect is as shown in fig. 22. Therefore, the user can quickly know whether the vehicle is in the coverage area of the high-precision map and the approximate position of the vehicle in the high-precision map, and can also know the coverage area of the high-precision map of the area where the vehicle is located.

In one embodiment, when the user wants to exit the display mode of the composite map, the high-precision map icon can be clicked again, and the terminal device displays the second interactive interface in response to the triggering operation of the high-precision map icon by the user. The user can select the traditional map option in the second interactive interface, and in response to the triggering operation of the traditional map option, the terminal equipment quits the display of the composite map and switches back the interactive interface of the traditional map.

In another embodiment, in the process of displaying the second interactive interface, the terminal device may click any position of the graying area beside the menu board when the user wants to exit the second interactive interface, the terminal device exits the display of the second interactive interface when detecting the click operation of the user on any position of the graying area beside the menu board, and the interface returns to the display of the interactive interface of the conventional map.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
