[0032] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0033] In this document, "plurality" refers to two or more. "And / or" describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates an "or" relationship between the associated objects.

[0034] In related technologies, the terminal displays a map within a certain range around the user through the navigation interface, and indicates the current position of the vehicle driven by the user through the vehicle logo. The vehicle logo is controlled to move in the map of the navigation interface according to the position change of the vehicle, reflecting the driving route of the vehicle in real time.

[0035] However, the display method of the navigation interface in the related art makes the movement range of the vehicle icon in the navigation interface relatively large. Especially when driving a vehicle, it is difficult for the user to quickly and accurately determine the position of the vehicle icon on the map with a single glance. In other words, it may take multiple or long observations to clearly determine the current position of the vehicle and the subsequent driving route, which affects driving safety. Figure 1 As shown, the navigation interface 101 displays a map and an object identifier 102. The terminal controls the movement of the object identifier 102 in real time based on the changes in the location of the navigation object. If the user does not check the navigation interface for a long period of time, the position of the object identifier 102 may differ significantly between the two views of the navigation interface, making it difficult for the user to quickly determine the location of the object identifier 102 in the navigation interface. Furthermore, when the vehicle's driving direction changes (e.g., turning or making a U-turn), the object identifier or map changes significantly with the change in driving direction, which can easily cause dizziness in the user.

[0036] In order to solve the above technical problems, the present application provides a method for displaying a navigation interface, which adjusts the display position of an object identifier in a target area and updates an electronic map based on the display position of the object identifier. While ensuring that the object identifier is always displayed in a fixed visual focus area in the navigation interface, the degree of change of the map is slowed down as much as possible, so that the user can quickly determine the position of the vehicle, while reducing the dizziness caused by map changes when the driving direction changes. The method for displaying a navigation interface provided in the embodiment of the present application can be applied to terminals such as navigators, smart phones, and tablet computers. In a possible implementation, the method for displaying a navigation interface provided in the embodiment of the present application can be implemented as an application or a part of an application, and installed in a terminal, so that the terminal has positioning and navigation functions. For the convenience of description, the following embodiments are described by taking the application of the method for displaying a navigation interface to a terminal as an example, but this does not constitute a limitation.

[0037] Figure 2A flowchart of a method for displaying a navigation interface provided by an exemplary embodiment of the present application is shown. This embodiment is described by taking the method applied to a terminal with a navigation function as an example, and the method includes the following steps.

[0038] Step 201: Display an object identifier of a navigation object in a target area of ​​a navigation interface. The target area is a visual focus area at a fixed position in the navigation interface, and the object identifier is displayed on an electronic map.

[0039] In one possible implementation, in response to receiving an operation to enable the navigation function, the terminal obtains current location information and displays a navigation interface based on the current location information. The navigation interface includes an electronic map and an object identifier of a navigation object, where the position of the object identifier on the electronic map can reflect the geographic location of the navigation object. The navigation object refers to the object being navigated, such as a user who has enabled the navigation function and a vehicle driven by the user. The terminal determines its own location as the location of the navigation object.

[0040] Optionally, the electronic map of the navigation interface also displays navigation route indication information, which is text information or graphic information, such as a guide line that takes the object identifier as the starting point and is used to indicate the driving direction.

[0041] Schematically, the terminal displays the object identifier at a default position in the navigation interface and displays an electronic map based on the current position information of the navigation object, thereby simulating the position and movement of the navigation object in the real environment based on the object identifier and the electronic map.

[0042] The terminal displays the object identifier in the target area of ​​the navigation interface, where the target area is a fixed visual focus area. The visual focus area is an area that is convenient for focusing the user's line of sight. For example, based on the user's driving and scanning behavior habits of the terminal interface, the visual focus area is determined to be located on the right side of the navigation interface, and the distance between each boundary of the visual focus area and each boundary of the navigation interface is not less than the distance threshold, that is, the visual focus area is located at a position that is not a corner of the interface and not an edge of the interface, and its position is fixed. In addition, in order to focus the user's line of sight, the user can roughly determine the display position of the object identifier in the navigation interface before viewing the navigation interface. The area of ​​the visual focus area is small, less than a preset area threshold, for example, the display area of ​​the visual focus area is 1 / 40 of the display area of ​​the navigation interface. In one possible embodiment, the visual focus area (i.e., the target area) in the navigation interface is obtained by pre-rasterizing the navigation interface.

[0043] The target area is not perceptible, that is, the user cannot perceive the existence of the target area in the interface through the navigation interface, and can only perceive that the object logo is displayed at a fixed position.

[0044] Optionally, the edge of the object identifier cannot exceed the edge of the target area, or the center of the object identifier cannot exceed the edge of the target area, which is not limited in this embodiment of the present application.

[0045] Indicative, Figure 3 The navigation interface 301 includes an electronic map 302 and an object identifier 303. When the user drives the vehicle in a straight line along the current lane, the terminal adjusts the electronic map 302 downward and keeps the object identifier 303 at the current display position.

[0046] Step 202: In response to a change in the driving state of the navigation object, adjust the display position of the object identifier in the target area.

[0047] In one possible embodiment, when the navigation object is traveling straight ahead on the current road and its driving status remains unchanged, the terminal displays the navigation object's driving progress by fixing the object identifier and adjusting the electronic map. For example, if the navigation object is traveling due north in the current lane, the terminal fixes the object identifier and adjusts the electronic map downward in the navigation interface, allowing the user to easily determine the vehicle's location with a single glance. When the navigation object's driving status is about to change, such as during a lane change, a turn, a U-turn, or entering a fork in the road, if the terminal continues to display the driving progress and navigation route by simply adjusting the electronic map, the electronic map must be significantly altered (moved and rotated) within a short period of time. Such significant changes in the electronic map can cause user disorientation and hinder safe driving. Therefore, the terminal no longer displays the navigation object's driving progress by simply moving the electronic map. Instead, it adjusts the display position of the object identifier within the target area and simultaneously controls the relative movement of the electronic map to minimize and slow down the changes in the electronic map, thereby reducing disorientation and allowing the user to quickly understand how to change the driving status through the navigation interface display.

[0048] The target area is a small and fixed visual focus area in the navigation interface. Therefore, even if the terminal adjusts the display position of the object logo, the object logo is always located in the target area, and the user can still quickly locate the display position of the object logo.

[0049] Optionally, when the driving status of the navigation object changes, the terminal only adjusts the display position of the object logo in the target area and fixes the electronic map to reduce the dizziness caused by large changes in the electronic map; or, the terminal adjusts the display position of the object logo and adjusts the display of the electronic map at the same time, thereby reducing the degree of change of the two relative to the navigation interface.

[0050] Step 203 : In response to the display position of the object identifier in the target area being adjusted, the display of the electronic map is updated based on the display position of the object identifier in the target area.

[0051] After the object marker's display position is adjusted, the terminal must update the electronic map based on the adjusted object marker's display position. This ensures that changes in the electronic map align with the changes in the object marker's display position, achieving the effect of displaying the object marker's changing driving status along the navigation route. Since the object marker's display position is adjusted based on the changing driving status, changes to the electronic map can be slowed down, preventing significant changes that would require the user to check the navigation interface multiple times or for extended periods of time to determine their current location and route.

[0052] To sum up, in the embodiment of the present application, the display position of the object identifier is adjusted and the electronic map is updated to display the changes in the driving status, and the object identifier is located in the target area before and after the adjustment, so that no matter what the driving status is, the object identifier is always displayed in the target area, limiting the display area of ​​the object identifier. While displaying the changes in the driving status, it can ensure that the user can determine the current position and subsequent driving route by quickly scanning during driving, thereby improving the efficiency of the user in determining the position and viewing the navigation route, and ensuring driving safety.

[0053] In a possible implementation, the map in the navigation interface is a three-dimensional map, and the object identifier is a three-dimensional model of the navigation object (eg, a car model). Figure 4 A flowchart of a method for displaying a navigation interface provided by another exemplary embodiment of the present application is shown. This embodiment is described by taking the method applied to a terminal with a navigation function as an example, and the method includes the following steps.

[0054] Step 401: Using a first perspective as a navigation perspective, displaying an object identifier in a target area. The object identifier is displayed on an electronic map under the first perspective.

[0055] In one possible implementation, the terminal displays the electronic map and object identifiers from a first perspective by default. Illustratively, the first perspective is the shooting perspective of a virtual camera. The terminal generates a three-dimensional map and object identifiers of navigation objects through three-dimensional modeling, and controls the virtual camera to shoot from behind the object identifier at a predetermined top-down angle, thereby displaying the electronic map and object identifiers captured by the virtual camera on the navigation interface.

[0056] During normal driving, when there is no need to change the driving status, in order to facilitate the user to view the road conditions ahead and changes in the navigation route, the terminal controls the virtual camera to shoot at a lower altitude and a smaller downward angle (for example, 20°) to obtain an electronic map with a long-distance field of view, so that the user can see the electronic map and navigation route at a farther distance through the navigation interface, which is convenient for the user to grasp the approximate changes of a longer navigation route.

[0057] The specific implementation of step 401 can refer to the above step 201, and will not be repeated here in this embodiment of the present application.

[0058] Step 402 : In response to a change in the driving state of the navigation object, determining an adjustment method for the object identifier based on the type of change in the driving state.

[0059] Among them, the types of changes in driving status include changes in driving direction (such as turning, turning around, entering a fork in the road, etc.) and changes in driving lanes (lane changes). The terminal adjusts the object identifier differently under the two types of changes. Specifically, the adjustment methods of the object identifier within the target area include horizontal adjustment and vertical adjustment. Step 402 includes the following steps:

[0060] In step 402a, in response to the change type being a change in driving direction and the distance between the object identifier and the target node being less than a first distance threshold, the adjustment mode is determined to be a longitudinal adjustment, and the target node is the node in the electronic map where the driving direction has changed.

[0061] It is worth mentioning that in an embodiment of the present application, when the change type is a change in driving direction, the terminal does not adjust the display position of the object identifier after the actual driving direction of the navigation object begins to change, but performs the step of adjusting the display position of the object identifier before the actual driving direction begins to change. That is, the terminal determines whether the driving direction of the navigation object is about to change based on the pre-generated navigation route and the current position of the navigation object, that is, whether the object identifier reaches a first distance threshold from the target node. If so, the display position of the object identifier begins to be adjusted longitudinally.

[0062] In response to the impending change in the driving direction of the navigation object, the terminal controls the relative movement of the object identifier and the electronic map. By controlling the small movement of the object identifier within the target area, the degree of change of the electronic map is reduced to avoid the user feeling dizzy due to drastic changes in the electronic map when the object identifier is fixed.

[0063] In one possible implementation, the terminal determines the geographic location of the navigation object in real time and, based on a predetermined navigation route, determines whether the navigation object needs to change direction. If it is determined that the navigation object needs to change direction after traveling a preset distance, the terminal longitudinally adjusts the display position of the object identifier within the target area. The object identifier position adjustment is completed before the navigation object begins to change direction, and the navigation interface displays the moved electronic map and object identifier. This allows the user to more clearly observe the nearby navigation route and understand how to change direction, while minimizing the extent of changes to the electronic map.

[0064] In response to the distance between the object identifier and the target node being less than a first distance threshold (i.e., the distance between the location corresponding to the navigation object and the target node is less than the actual distance corresponding to the first distance threshold), the terminal vertically adjusts the display position of the object representation. The target node is the node where the driving direction indicated by the navigation route on the map changes. For example, if the navigation route indicates that the next intersection on the map requires a left turn, then the intersection is the target node.

[0065] For example, developers have determined through testing that starting the relative movement of the map and the object marker 50 meters before changing direction allows for the relative movement to end at an appropriate time, that is, before the navigation object reaches the location corresponding to the target node. Therefore, the terminal is configured to determine the first distance threshold based on 50 meters and the current map scale. For example, the first distance threshold is 5 cm.

[0066] Step 402b: In response to a change in the driving state of the navigation object, where the change type is a driving lane change, determining that the adjustment method is a lateral adjustment.

[0067] When the change type of the driving state is a driving lane change, the terminal determines that the adjustment method of the object identifier is lateral adjustment.

[0068] Unlike turns and U-turns, when a vehicle changes lanes, its road and direction remain unchanged, but its lane changes. In one possible implementation, the map in this embodiment is a lane-level three-dimensional map. In response to a change in the navigation object's lane, the terminal controls the relative movement of the object identifier and the map, reflecting the navigation object's lane change in real time.

[0069] Step 403: Adjust the display position of the object identifier in the target area according to the adjustment method.

[0070] After determining an adjustment method for the object identifier based on the type of change in the driving state, the terminal adjusts a display position of the object identifier within the target area according to the adjustment method.

[0071] When the driving state change type is a driving direction change and the terminal determines that the adjustment method is longitudinal adjustment, step 403 further includes the following steps:

[0072] Step 403a: Switch the navigation perspective from the first perspective to the second perspective, where the viewing distance under the first perspective is greater than the viewing distance under the second perspective.

[0073] In one possible embodiment, the navigation interface corresponds to at least two navigation perspectives, namely, at least a first perspective and a second perspective, wherein the first perspective is a long-distance perspective and the second perspective is a short-distance perspective, namely, the field of view distance under the first perspective is greater than the field of view distance under the second perspective (for example, the top-down angle and height of the virtual camera under the first perspective are less than the top-down angle and height of the virtual camera under the second perspective). The terminal displays the electronic map and object identifier under the first perspective by default. In response to the distance between the object identifier and the target node being less than the first distance threshold, the terminal switches the navigation perspective of the navigation interface from the first perspective to the second perspective, for example, controlling the virtual camera to move upward on a sphere with the object identifier as the center of the sphere, and the virtual camera is always directed towards the object identifier.

[0074] When the navigation perspective switches from the first perspective to the second perspective, the user's attention can be shifted from the distant navigation route to the nearby navigation route, allowing the user to pay attention to how the driving direction ahead changes.

[0075] During the perspective switching process, the terminal still updates the display of the electronic map based on the driving direction and speed of the navigation object.

[0076] Indicative, such as Figure 5 As shown, the navigation interface 501 includes an electronic map 502 and an object identifier 503. In response to determining that the distance between the object identifier 503 and the target node is less than 5 cm, that is, the navigation object needs to drive to the right front after 50 m and enter the fork in the road, the terminal changes the navigation perspective from the first perspective (corresponding to Figure 5 The perspective of the first picture) switches to the second perspective (corresponding to Figure 5 During the perspective switching process, the display of the electronic map 502 is still updated based on the driving situation of the navigation object, that is, the electronic map 502 is moved downward.

[0077] Step 403b: Adjust the display position of the object identifier upward within the target area and increase the map scale of the electronic map.

[0078] The display position of the target node in the navigation interface remains unchanged as the map scale increases. When the navigation perspective switches to the second perspective, the terminal controls the relative movement of the map and the object identifier to minimize the degree of map change. It is worth noting that the adjustment range of the object identifier is always within the target area. If the object identifier has been adjusted to the edge of the target area, the display position of the object identifier will stop being adjusted.

[0079] If the navigation target's driving progress is simply displayed by moving the electronic map and adjusting the object identifier, the electronic map will still change significantly. Therefore, the terminal increases the electronic map scale, that is, continuously zooming in on the map while maintaining the displayed position of the target node unchanged, thereby achieving the effect of the object identifier continuously moving toward the target node. Simultaneously, the terminal adjusts the displayed position of the object identifier upward, slowing the speed of map scale magnification. This allows the user to clearly see the changes in driving direction at the target node, while also reducing the degree of electronic map changes and the feeling of dizziness. At the same time, it ensures that the object identifier moves within a fixed visual focus area, making it easier for the user to quickly determine the vehicle's position.

[0080] When the driving state change type is a driving lane change and the terminal determines that the adjustment method is a lateral adjustment, step 403 further includes the following steps:

[0081] Step 403c: Determine the lane change direction.

[0082] The terminal determines the position change of the navigation object through real-time positioning, and when it is determined that the lane where the navigation object is located has changed, determines the lane change direction of the navigation object.

[0083] Step 403d: Laterally adjust the display position of the object identifier in the target area based on the lane change direction.

[0084] Based on the lane-changing direction of the navigation object, the terminal controls the relative movement of the object identifier and the map accordingly, that is, controls the object identifier to move in the navigation interface according to the lane-changing direction of the navigation object, and controls the electronic map to move in the opposite direction based on the display position of the object identifier, thereby achieving the display effect of the object identifier changing lanes on the map. Moreover, since the display position of the object identifier is adjusted, the degree of change of the electronic map can be reduced while ensuring that the object identifier is within the identifier display range.

[0085] In one possible implementation, step 403d includes the following steps:

[0086] In response to the lane change direction being a right lane change, the display position of the object marker in the target area is adjusted rightward; in response to the lane change direction being a left lane change, the display position of the object marker in the target area is adjusted leftward.

[0087] Optionally, the terminal first adjusts the display position of the object identifier based on the lane change direction, and then adjusts the electronic map laterally when the display position of the object identifier cannot be adjusted further. Alternatively, the terminal adjusts both the object identifier and the electronic map simultaneously. Specifically, if the lane change direction is right, the terminal controls the object identifier to move right within the target area and controls the electronic map to move left. If the lane change direction is left, the terminal controls the object identifier to move left within the target area and controls the electronic map to move right.

[0088] Indicative, Figure 7 The figure shows how the navigation interface changes when the navigation object changes lanes. Based on the positioning information, the terminal determines that the navigation object has moved one lane to the right, that is, the lane change direction is right. Therefore, the terminal controls the object identifier 703 in the navigation interface 701 to move right within the target area, and simultaneously controls the electronic map 702 to move left.

[0089] Step 404 : In response to the object identifier being adjusted to the edge of the target area, the display of the electronic map is updated based on the display position of the object identifier in the target area.

[0090] Optionally, the terminal synchronously updates the display of the electronic map during the process of adjusting the display position of the object identifier, or the terminal fixedly displays the electronic map when adjusting the display position of the object identifier, and updates the electronic map after the object identifier is adjusted to the edge of the target area.

[0091] When the type of change in the driving state is a change in the driving direction and the adjustment method of the object identifier is longitudinal adjustment, step 404 includes the following steps:

[0092] Step 404a: in response to the object identifier being adjusted to the upper edge of the target area and the map scale reaching a first scale, rotating the electronic map based on the display position of the object identifier in the target area.

[0093] When the map scale is zoomed in to the first scale and cannot be further zoomed in, the terminal continues to move the map, even if the target node moves downward, thereby achieving a display effect in which the object identifier is constantly approaching the target node. During this process, if the object identifier has already moved to the upper edge of the identifier display area before the map scale is zoomed in to the first scale, the terminal controls the object identifier to remain stationary and only moves the map downward until the object identifier moves to the upper edge. If the object identifier has not moved to the upper edge, the terminal controls the object identifier to move upward and simultaneously controls the map to move downward.

[0094] Indicative, such as Figure 5 As shown, after the terminal switches the navigation perspective to the second perspective, the control object identifier 503 moves upward in the identifier display area and increases the map scale. Figure 5 Comparing the second and third images, we can see that the terminal maintains the display position of the target node (i.e., the fork in the road ahead on the right) in navigation interface 501. Object identifier 503 is simply moved and the map scale is increased to achieve the effect of moving the object identifier 503 toward the target node. The user can now view the enlarged electronic map on the navigation interface and quickly identify changes in driving direction along the navigation route.

[0095] In order to facilitate the demonstration of the change process of map and object identification, such as Figure 6 As shown, navigation interface 601 is gridded (the dotted lines corresponding to the grid are not visible in the actual navigation interface), and object marker 603 is located within a fixed visual focus area (i.e., within the grid corresponding to the third column horizontally and the fourth row vertically). Initially, object marker 603 is located at the lower edge of the target area, and the terminal only moves electronic map 602. Then, the navigation perspective switches to the second perspective, and the terminal controls object marker 603 to move upward within the target area and increases the map scale.

[0096] The object identifier begins to change its driving direction after reaching the target node. At this time, the terminal has completed the adjustment of the object identifier and the scale method, thereby controlling the electronic map to move and rotate relative to the object identifier based on the change in the driving direction of the navigation object, so as to achieve the display effect of the object identifier changing its driving direction at the target node.

[0097] Accordingly, after the navigation object leaves the target node, the terminal needs to restore the navigation perspective and the display position of the object identifier so as to continue to observe the distant navigation route from a long-distance perspective and prepare to reach the next node. Therefore, after the above step 404, the display method of the navigation interface provided by the embodiment of the present application further includes the following steps:

[0098] Step 1: In response to the distance between the object identifier and the target node being greater than a second distance threshold, adjusting the display position of the object identifier in the target area.

[0099] In response to the distance between the object identifier and the target node being greater than the second distance threshold, the electronic map and the object identifier are controlled to move relative to each other. In one possible implementation, step 1 includes the following steps:

[0100] In response to the distance between the object identifier and the target node being greater than a second distance threshold, the display position of the object identifier is adjusted downward within the target area, and the map scale is reduced.

[0101] Optionally, in response to the distance between the object identifier and the target node being greater than a second distance threshold, and the distance between the object identifier and the next target node being greater than a first distance threshold, the terminal controls the electronic map and the object identifier to move relative to each other; in response to the distance between the object identifier and the target node being greater than the second distance threshold, and the distance between the object identifier and the next target node being less than the first distance threshold, the terminal controls the object identifier to remain stationary at the current display position, and updates the display of the electronic map only based on the driving direction.

[0102] Step 2: in response to the object identifier being adjusted to the edge of the target area, updating the display of the electronic map based on the display position of the object identifier in the target area and the driving direction of the navigation object.

[0103] In one possible implementation, step 2 includes the following steps:

[0104] In response to the object identifier being adjusted to the lower edge of the target area and the map scale reaching a second scale, the display of the electronic map is updated based on the display position of the object identifier in the target area and the driving direction of the navigation object.

[0105] In response to the distance between the object identifier and the target node being greater than a second distance threshold, the terminal first controls the object identifier to move downward within the target area, while reducing the map scale to achieve a display effect in which the object identifier is far away from the target node; when the map scale is reduced to the second scale, the terminal controls the electronic map to move downward. If the object identifier has been adjusted to the lower edge of the target area at this time, only the electronic map is moved. If the object identifier has not reached the lower edge of the target area, both the object identifier and the electronic map are controlled to move downward simultaneously, but the relative movement speed of the two is consistent with the relative movement speed of the navigation object and the actual road (i.e., the map movement speed is greater than the movement speed of the object identifier).

[0106] In another possible embodiment, in response to the distance between the object identifier and the target node being greater than a second distance threshold, the terminal controls the electronic map and the object identifier to move downward. When the object identifier moves to the lower edge of the identifier display area, the terminal controls the object identifier and the electronic map to remain stationary, gradually reduces the scale of the electronic map, and continues to move the electronic map when the map scale is reduced to the second scale.

[0107] When the driving state change type is a driving lane change and the object identifier adjustment method is a lateral adjustment, step 404 includes the following steps:

[0108] In step 404b, in response to the lane change direction being a right lane change and the object marker being adjusted to the right edge of the target area, the electronic map is adjusted leftward based on the display position of the object marker.

[0109] In step 404c, in response to the lane change direction being a left lane change and the object marker being adjusted to the left edge of the target area, the electronic map is adjusted rightward based on the display position of the object marker.

[0110] When the terminal determines the lane change method of the navigation object and adjusts the display position of the object indicator accordingly, it adjusts the electronic map in the opposite direction. This causes both the electronic map and the object indicator to move in opposite directions simultaneously. This reduces the degree of change in the navigation interface compared to adjusting only the position of the map or the object indicator. If the object indicator moves to the edge of the target area and the navigation object continues to change lanes, the terminal stops adjusting the display position of the object indicator, freezes the display, and continues adjusting the electronic map. This causes the display position of the object indicator to change significantly, making it difficult for the user to quickly determine the vehicle's location.

[0111] In another possible implementation, when the object identifier has not moved to the edge of the target area, the navigation object may have stopped changing lanes. In this case, the terminal stops adjusting the display position of the object identifier and continues to update the display of the electronic map. After step 403, the method for displaying the navigation interface provided in this embodiment of the present application further includes the following steps:

[0112] In response to the object identifier not moving to the edge of the target area and the navigation object stopping lane change, the object identifier in the target area is fixedly displayed, and the display of the electronic map is updated based on the display position of the object identifier and the driving direction of the navigation object.

[0113] The terminal adjusts the display position of the object identifier in real time based on the position changes of the navigation object. When the navigation object stops changing lanes, if the object identifier has not moved to the edge of the target area, the target object is fixedly displayed and the electronic map display continues to be updated based on the driving direction of the navigation object.

[0114] In an embodiment of the present application, when it is determined that the navigation object is about to reach the target node, the navigation perspective is first switched from a first perspective of a long-distance field of view to a second perspective of a close-range field of view, and then combined with changing the map scale, adjusting the display position of the object identifier in the target area, and moving the electronic map, while ensuring that the object identifier is always displayed in a fixed grid area, it can not only reduce the degree of change of the electronic map and reduce the user's dizziness, but also make it easier for the user to clearly view the route changes at the target node, making it convenient for the user to quickly change the driving direction according to the navigation route, improving driving efficiency, and ensuring driving safety.

[0115] In a possible implementation, the terminal determines in real time based on the geographic location of the navigation object and the navigation route whether the driving direction of the navigation object has changed, that is, whether it is necessary to control the relative movement of the object identifier and the map. The above step 203 also includes the following steps:

[0116] In response to a change in a driving road in a navigation route, a navigation instruction is generated based on the change in the driving road in the navigation route; in response to a navigation object driving according to the navigation instruction and a change in driving status, a display position of the object identifier in a target area is adjusted, and the display of the electronic map is updated.

[0117] In another possible implementation, the above-mentioned navigation instructions are generated by the server and sent to the terminal. The terminal sends the positioning information of the navigation object to the server in real time. The server determines whether the driving road of the navigation object needs to be changed (i.e., whether the navigation object is about to reach the target node) based on the location of the navigation object and the pre-generated navigation route. If so, a navigation instruction is generated and sent to the terminal. After receiving the navigation instruction, the terminal prompts the user to change the driving direction according to the navigation instruction through the interface or voice. If it is detected that the navigation object is driving according to the navigation instruction, the display position of the object logo is adjusted and the electronic map is updated. The interaction process between the terminal and the server is as follows: Figure 8 As shown: Step 801, the server calculates the relationship between the current lane of the navigation object and the navigation route's guide lane in real time. Step 802, the server determines whether the current lane of the navigation object matches the navigation route's guide lane. If so, the server returns to step 801; if not, the server proceeds to step 803. Step 803, the server sends a navigation instruction to the terminal prompting it to change direction. Step 804, the server determines whether the navigation object is traveling in accordance with the navigation instruction. If so, the server proceeds to step 805; if not, the server returns to step 803. Step 805, the display position of the object identifier within the target area is adjusted, and the electronic map display is updated based on the display position of the object identifier.

[0118] In one possible implementation, when the driving state of the navigation object does not change (driving in a straight line in a certain direction), since the relative position between the object identifier and the electronic map also changes according to the fixed driving direction, the terminal fixes the object identifier and updates the electronic map to display the driving process of the object identifier and the surrounding environment. Figure 9 A flowchart of a method for displaying a navigation interface provided by another exemplary embodiment of the present application is shown. This embodiment is described by taking the method applied to a terminal with a navigation function as an example, and the method includes the following steps.

[0119] Step 901: Display an object identifier of a navigation object in a target area of ​​a navigation interface. The target area is a visual focus area at a fixed position in the navigation interface. The object identifier is displayed on an electronic map.

[0120] The specific implementation of step 901 can refer to the above-mentioned step 201, and will not be repeated here in this embodiment of the present application.

[0121] Step 902 : In response to the driving state of the navigation object not changing, the object identifier in the target area is fixedly displayed, and the display of the electronic map is updated based on the display position of the object identifier and the driving direction of the navigation object.

[0122] In one possible implementation, when the navigation object is traveling straight ahead on the current road and its driving status remains unchanged, the terminal displays the object's identifier in a fixed manner and adjusts the electronic map to display the navigation object's driving progress. For example, if the navigation object is traveling due north in the current lane, the terminal will fix the object identifier and move the electronic map downward in the navigation interface.

[0123] Optionally, the terminal determines the moving speed of the electronic map based on the driving speed of the navigation object and the map scale corresponding to the map; or, the terminal determines the location information of the navigation object once every preset time period and moves the electronic map based on the location information.

[0124] In an embodiment of the present application, when the driving status of the navigation object has not changed, the terminal displays the object identifier in a fixed manner, and only by adjusting the electronic map can the display effect of the object identifier moving in the electronic map be achieved. The user can determine that the object identifier is always displayed in the same position, so that the current position of the navigation object can be obtained from the navigation interface by a quick scan, thereby improving the efficiency of the user in determining the position and viewing the navigation route, and ensuring driving safety.

[0125] The above embodiments illustrate the process of the terminal executing the method for displaying the navigation interface in three-dimensional maps and three-dimensional model scenarios. The method for displaying the navigation interface provided in the embodiments of the present application can also be applied to displaying the navigation interface corresponding to two-dimensional maps and two-dimensional logos.

[0126] The above embodiments illustrate the process of the terminal displaying the object identification based on the target area and moving the map and the object identification relative to each other under various driving conditions of the navigation object. Since the navigation interface is large in size and the object identification is small in size, it is necessary to determine a suitable target area for user viewing. Figure 10 A flowchart of a method for displaying a navigation interface provided by another exemplary embodiment of the present application is shown. This embodiment is described by taking the method applied to a terminal with a navigation function as an example, and the method includes the following steps.

[0127] Step 1001: Determine a target area in a second display area.

[0128] In one possible embodiment, the navigation interface includes a first display area and a second display area, wherein the first display area and the second display area jointly display a map. A guide panel containing navigation guidance information is superimposed above the map in the first display area. In addition, the guide panel also displays basic function controls such as voice control and navigation shutdown control.

[0129] The terminal determines the target area based on the second display area, and step 1001 further includes the following steps:

[0130] Step 1001a: performing rasterization processing on the second display area.

[0131] In one possible implementation, the terminal performs grid processing on the second display area or the entire navigation interface. For example, the terminal divides the second display area into m columns horizontally and n rows vertically to generate n*m ​​fixed grid areas, and determines a target grid area from the obtained n*m grid areas as the target area.

[0132] Step 1001b: determine the target grid area in the second display area as the target area, and the midpoint of the target grid area is the golden section point of the second display area.

[0133] In one possible implementation, to improve the convenience of viewing the navigation interface and facilitate quick identification of the vehicle's location, the terminal determines an indicator display area based on the golden section points of the second display area. For example, the terminal determines the horizontal and vertical golden sections of the second display area, and identifies the grid area containing the intersection of the two golden sections as the target grid area. The display area corresponding to the target grid area is the target area.

[0134] Indicative, such as Figure 11 As shown, navigation interface 1101 includes a stable display area (first display area) 1102 on the left and a dynamic display area (second display area) 1104 on the right. A guide panel 1103 is superimposed above the map in stable display area 1102. The terminal rasterizes dynamic display area 1104 and determines a target grid area 1105 as the target area based on the golden section point.

[0135] Step 1002: Display the object identifier of the navigation object in the target area of ​​the navigation interface.

[0136] Step 1003: In response to a change in the driving state of the navigation object, adjust the display position of the object identifier in the target area.

[0137] Step 1004 : In response to the display position of the object identifier in the target area being adjusted, the display of the electronic map is updated based on the display position of the object identifier in the target area.

[0138] The specific implementation of steps 1002 to 1004 can refer to the above steps 201 to 203, and will not be repeated here in this embodiment of the present application.

[0139] In an embodiment of the present application, the terminal first rasterizes the second display area of ​​the navigation interface, and then determines the target area from the generated grid areas based on the golden section, and controls the object identifier to always be displayed in the target area, thereby improving the readability of the navigation interface and the convenience for the user to view the location of the vehicle.
