Embodiments of this disclosure relate to the technical field of Internet of Vehicles, including a display of a navigation interface.
At present, online navigation functions are widely used. For example, online car-hailing application software, navigation application software, map application software, and the like provide vehicle traveling navigation functions.
In the related art, a terminal displays a map within a certain range around a user through a navigation interface, indicates a current position of a vehicle driven by the user through a vehicle identity, controls the vehicle identity to move in the map of the navigation interface according to a position change of the vehicle, and reflects a driving route of the vehicle in real time.
However, a display mode of the navigation interface in the related art causes a large movement range of the vehicle identity in the navigation interface. Especially when driving a vehicle, it is difficult for a user to quickly and accurately determine the position of a vehicle identity in the map through one glance. That is, multiple or long-term observations may be applied to determine the current position of the vehicle and a subsequent traveling route, thus affecting driving safety.
Embodiments of this application provide a navigation interface display method and apparatus, a terminal, and a non-transitory computer-readable storage medium. The technical solutions can be shown as follows:
According to an aspect, a method of a display of a navigation interface is provided. In the method, a representative model of a vehicle is displaced in an identity display region of the navigation interface. The identity display region indicates a view focus region of a user in the navigation interface of a terminal located inside the vehicle. The representative model is displayed on an electronic map on the navigation interface. A display position of the representative model is adjusted in the identity display region based on a change of a traveling state of the vehicle. A display configuration of the electronic map is updated in the navigation interface based on the adjusted display position of the representative model in the identity display region.
According to another aspect of the disclosure, an apparatus is provided. The apparatus includes processing circuitry. The processing circuitry can be configured to perform any of the described methods of a display of a navigation interface.
Aspects of the disclosure also provide a non-transitory computer-readable medium storing instructions which when executed by a computer for video decoding cause the computer to perform any of the described methods of a display of a navigation interface.
The technical solutions provided in the embodiments of this disclosure can include beneficial effects as follows:
In the embodiments of this disclosure, by adjusting a display position of an object identity (e.g., a presentative model of a navigation object) and updating an electronic map, a change situation of a traveling state is shown. In addition, before and after the object identity is adjusted, the object identity is located in an identity display region. Accordingly, the object identity is displayed in the identity display region regardless of the traveling state, and a display region of the object identity is limited. While showing the change situation of the traveling state, it can be ensured that a user determines the current position and a subsequent traveling route through a quick glance during the driving process. Thus, the efficiency of the user is increased in determining the position and viewing a navigation route, and the safety of driving is ensured.
In the related art, a terminal displays a map within a certain range around a user through a navigation interface, indicates a current position of a vehicle driven by the user through a vehicle identity, controls the vehicle identity to move in the map of the navigation interface according to a position change of the vehicle, and reflects a driving route of the vehicle in real time.
However, a display mode of the navigation interface in the related art causes a large movement range of the vehicle identity in the navigation interface. Especially when driving a vehicle, it is difficult for a user to quickly and accurately determine the position of a vehicle identity in the map through one glance. That is, multiple or long-term observations may be applied
to determine the current position of the vehicle and a subsequent traveling route, thus affecting driving safety. As shown in
In order to solve the foregoing technical problem, this disclosure provides a navigation interface display method. A display position of an object identity is adjusted in an identity display region, and an electronic map is updated based on the display position of the object identity. While ensuring that the object identity is displayed in a fixed visual focus region (or view focus region) in a navigation interface, the degree of change of the map is alleviated as much as possible, so that a user can quickly determine the position of a vehicle, and the feeling of dizziness caused by the change of the map when a traveling direction is changed is also reduced. The navigation interface display method according to an embodiment of this disclosure is applicable to a terminal such as a navigator, a smartphone, or a tablet personal computer. In a possible implementation, the navigation interface display method according to this embodiment of this disclosure may be implemented as an application or part of an application, and installed into the terminal, so that the terminal has positioning and navigation functions. For ease of description, the various embodiments below describe an example in which the navigation interface display method is applied to a terminal, but the various embodiments are not limited thereto.
In step 201, an object identity of a navigation object is displayed in an identity display region. The identity display region is a visual focus region (or a view focus region) in a navigation interface, and the object identity is displayed on an electronic map. The visual focus region (also referred to as view focus region) indicates a field of view focus from a user when the user watches the navigation interface.
In a possible implementation, when the terminal receives an enabling operation of a navigation function, the terminal obtains current position information and displays a navigation interface based on the current position information. The navigation interface includes an electronic map and an object identity of a navigation object. The position of the object identity in the electronic map can reflect a geographical position of the navigation object. The navigation object refers to an object to be navigated, for example, a user who enables the navigation function and a vehicle driven by the user. The terminal determines the position of the terminal as the position of the navigation object.
In an example, navigation route indication information is also displayed in the electronic map of the navigation interface. The navigation route indication information is text information or graphic information, such as a guide line with an object identity as a starting point for indicating a traveling direction.
Schematically, the terminal displays the object identity at a default position in the navigation interface and displays the electronic map based on the current position information of the navigation object, thereby simulating the position and movement situation of the navigation object in a real environment based on the object identity and the electronic map.
In order that the user searches for the object identity during the navigation process, the terminal displays the object identity in an identity display region of the navigation interface. The identity display region is a fixed visual focus region. The visual focus region is a region facilitating focusing of a user sight. For example, based on behavior habits of user driving and glancing at a terminal interface, it is determined that the visual focus region is located at a right position on the navigation interface, and the distance between each boundary of the visual focus region and each boundary of the navigation interface is not less than a distance threshold. That is, the visual focus region is not at an interface corner and an interface edge, and the position of the visual focus region is fixed. Furthermore, in order to focus the user sight to enable the user to approximately determine a display position of the object identity in the navigation interface before viewing the navigation interface, the area of the visual focus region is smaller than a preset area threshold. For example, the display area of the visual focus region is 1/40 of the display area of the navigation interface. In a possible implementation, the visual focus region (namely, the identity display region) in the navigation interface is obtained by gridding the navigation interface in advance.
The identity display region is not perceivable. That is, the user cannot perceive the presence of the identity display region in the interface through the navigation interface, and can perceive that the object identity is displayed at a fixed position.
In an example, the terminal may also provide the user with a setting function of the identity display region, whereby the user sets the identity display region where the object identity is located in the navigation interface based on navigation requirements of the user. For example, the user sets the identity display region in the center of the navigation interface. In an example, in order to prevent the user from mistakenly setting the identity display region, when the user inputs an identity display region to be set, the identity display region may also be uploaded to a background server of a navigation application, whereby the background server checks and fine-adjusts the identity display region to be set, thereby ensuring that the identity display region may meet the setting requirements.
In an example, the edge of the object identity may not extend beyond the edge of the identity display region, or the center of the object identity may not extend beyond the edge of the identity display region. This embodiment of this disclosure is not limited thereto.
In step 202, a display position of the object identity is adjusted in the identity display region based on a change of a traveling state of the navigation object.
In a possible implementation, when the navigation object travels straight in a current road and the traveling state does not change, the terminal displays a traveling process of the navigation object by fixing the object identity and adjusting the electronic map. For example, when the navigation object travels in the north direction in the current lane, the terminal fixes the object identity and adjusts the electronic map downwards in the navigation interface, so that the user may determine the position of the vehicle through one glance (the position of the vehicle has not changed in the navigation interface). When the traveling state of the navigation object is about to change, for example, in lane changing, turning, U-turning, entering a branch road, or the like, if the terminal displays the traveling process and a navigation route by adjusting the electronic map, the electronic map needs to be changed (moved and rotated) largely within a short time. The large change in the electronic map may make the user feel dizzy, which is not conducive to safe driving. Therefore, the terminal no longer displays the traveling process of the navigation object by simply moving the electronic map, but adjusts the display position of the object identity in the identity display region and controls the electronic map to move relatively so as to reduce and alleviate the degree of change of the electronic map as much as possible, thereby reducing the feeling of dizziness, so that the user can quickly learn how to change the traveling state through the display content of the navigation interface.
The identity display region is a small-sized and fixed visual focus region in the navigation interface. Therefore, even if the terminal adjusts the display position of the object identity, the object identity is located in the identity display region, and the user may still quickly determine the display position of the object identity without searching for the changed position of the object identity in the navigation interface. In a case that the object identity is small or the surrounding environment interferes too much, the efficiency of searching for the object identity in the navigation interface can be improved.
In an example, when the traveling state of the navigation object changes, the terminal adjusts the display position of the object identity in the identity display region, and fixes the electronic map, so as to reduce the feeling of dizziness caused by the large change in the electronic map. Or, the terminal adjusts the display position of the object identity and also adjusts displaying of the electronic map, so as to reduce the degree of change of the display position and the electronic map with respect to the navigation interface.
In step 203, a display (or display configuration) of the electronic map is updated based on the display position of the object identity in the identity display region in a case that the display position of the object identity is adjusted.
After the display position of the object identity in the identity display region is adjusted, it is indicated that the traveling state of the navigation object changes. By changing the display position of the navigation object identity in the identity display region, the change of the form state cannot be reflected. Correspondingly, the terminal also needs to update the electronic map based on the adjusted display position of the object identity, so that the change of the electronic map matches the change of the display position of the object identity to achieve a display effect that the object identity changes the traveling state along the navigation line. Since the display position of the object identity is adjusted based on the change situation of the traveling state, the change of the electronic map can be reduced, thereby avoiding that the user needs to view the navigation interface for several times or for a long time during the driving process to determine the current position and travel route due to the large change.
In summary, in this embodiment of this disclosure, by adjusting a display position of an object identity and updating an electronic map, a change situation of a traveling state is shown, and before and after the object identity is adjusted, the object identity is located in an identity display region, so that the object identity is displayed in the identity display region regardless of the traveling state, thereby limiting a display region of the object identity. While showing the change situation of the traveling state, it can be ensured that a user determines the current position and a subsequent traveling route through a quick glance during the driving process, thereby improving the efficiency of the user in determining the position and viewing a navigation route, and ensuring the safety of driving.
In a possible implementation, the map in the navigation interface is a three-dimensional map, and the object identity is a three-dimensional model (for example, car model) of the navigation object.
In step 401, an object identity is displayed in an identity display region with a first perspective as a navigation perspective. Accordingly, the object identity is displayed on an electronic map under the first perspective.
In a possible implementation, the terminal displays the electronic map and the object identity in the first perspective by default. Schematically, the first perspective is a photographing perspective of a virtual camera. The terminal generates a three-dimensional map and an object identity of the navigation object through three-dimensional modeling, and controls the virtual camera to photograph from the rear of the object identity at a certain overhead angle, thereby displaying the electronic map and the object identity photographed by the virtual camera through the navigation interface.
During a normal traveling process, when the traveling state does not need to be changed, in order that the user views the situation of a road ahead and the change situation of the navigation route, the terminal controls the virtual camera to photograph at a lower height and a smaller overhead angle (for example, 20°) so as to obtain the electronic map under a long-distance view. Thus, the user can view the electronic map and the navigation route at a longer distance through the navigation interface, and the user can master the approximate change situation of a longer navigation route.
An exemplary implementation of step 401 is similar to that of step 201, and is not described again in this embodiment of this disclosure.
In step 402, based on a change of a traveling state of a navigation object, an adjustment mode of the object identity is determined based on a change type of the traveling state.
The change type of the traveling state includes a traveling direction change (for example, turning, U-turning, entering a branch rod, and the like) and a traveling lane change (lane changing). The terminal adjusts the object identity in different modes under the two change types. For example, the adjustment mode of the object identity in the identity display region includes horizontal adjustment and vertical adjustment. Step 402 includes the following steps:
In an embodiment, the adjustment mode can be determined as a vertical adjustment based on the change type being a traveling direction change and a distance between the object identity and a direction change node being less than a first distance threshold. The direction change node is a node in the electronic map where a traveling direction changes.
In this embodiment of this disclosure, when the change type is the traveling direction change, the terminal does not adjust the display position of the object identity until an actual traveling direction of the navigation object starts to change, but executes the step of adjusting the display position of the object identity before the actual traveling direction starts to change. That is, the terminal determines whether the traveling direction of the navigation object is about to change based on the pre-generated navigation route and the current position of the navigation object, and it is determined whether the traveling direction is about to change by comparing whether the distance between the object identity and the node where the traveling direction changes is small. Correspondingly, the terminal has a first distance threshold. The distance between the object identity and the direction change node is obtained, and a relationship between the distance and the first distance threshold is determined by comparison. If the distance between the object identity and the direction change node is less than the first distance threshold, it is indicated that the traveling direction of the terminal is about to change, and the display position of the object identity starts to be adjusted vertically.
When the traveling direction of the navigation object is about to change, the terminal controls the object identity and the electronic map to move relatively, and the degree of change of the electronic map is weakened by controlling the small movement of the object identity in the identity display region, so as to avoid a stronger feeling of dizziness to the user due to a violent change of the electronic map when the object identity is fixed.
In a possible implementation, the terminal determines a geographical position of the navigation object in real time, and determines whether the navigation object needs to change the traveling direction based on the pre-determined navigation route. When it is determined that the navigation object needs to change the traveling direction after a preset distance, the display position of the object identity in the identity display region is adjusted vertically. The position adjustment of the object identity is completed before the navigation object starts to change the traveling direction. The moved electronic map and the object identity are displayed through the navigation interface. The user can more clearly observe the nearby navigation route and learn how to change the traveling direction, thereby reducing the degree of change of the electronic map as much as possible.
And when the distance between the object identity and the direction change node is less than the first distance threshold (namely, the distance between the navigation object and the position corresponding to the direction change node is less than an actual distance corresponding to the first distance threshold), the terminal vertically adjusts the display position of the object identity in the identity display region. The direction change node is a node where the traveling direction indicated by the navigation route in the map changes. For example, if the navigation route indicates that a left turn is applied at a next intersection in the map, the intersection is the direction change node.
Schematically, a developer determines, by testing, to control the relative movement between the map and the object identity at 50 m before changing the traveling direction, so that the relative movement can be ended at an appropriate timing, namely, can be completed before the navigation object arrives at the position corresponding to the direction change node. Thus, the terminal determines the first distance threshold based on 50 m and the current map scale. For example, the first distance threshold is 5 cm.
In an embodiment, the adjustment mode is determined as a horizontal adjustment based on a change of the traveling state of the navigation object and the change type being a traveling lane change.
When the traveling lane of the navigation object changes, unlike turning and U-turning, the traveling road and traveling direction of the vehicle are not changed, the lane where the vehicle is located changes, and the object identity needs to be horizontally moved. Correspondingly, in a possible implementation, when the change type of the traveling state is the traveling lane change, the terminal determines that the adjustment mode of the object identity is horizontal adjustment, such as rightward adjustment or leftward adjustment.
Unlike turning or U-turning, when the vehicle changes lanes, the road on which the vehicle travels and the traveling direction of the vehicle are not changed, but the lane on which the vehicle travels changes. In a possible implementation, the map in this embodiment of this disclosure is a three-dimensional map at a lane level. In response to the change in the traveling lane of the navigation object, the terminal controls the relative movement between the object identity and the map to reflect the lane changing process of the navigation object in real time.
In step 403, a display position of the object identity is adjusted in the identity display region according to the adjustment mode.
The change types of different traveling states correspond to different adjustment modes. For example, when the change type of the traveling state is the traveling lane change, the object identity needs to be adjusted horizontally, and when the change type of the traveling state is the traveling direction change, the object identity needs to be adjusted vertically. In a possible implementation, after the terminal determines the adjustment mode of the object identity based on the change type of the traveling state, the terminal adjusts the display position of the object identity in the identity display region according to the adjustment mode.
When the terminal determines the adjustment mode as vertical adjustment in a case that the change type of the traveling state is the traveling direction change, step 403 further includes the following steps:
In an embodiment, the navigation perspective is switched from the first perspective to a second perspective, where a field-of-view distance under the first perspective is greater than a field-of-view distance under the second perspective.
In a possible implementation, the navigation interface corresponds to at least two navigation perspectives, namely, includes at least a first perspective and a second perspective. The first perspective is a long-distance perspective, and the second perspective is a short-distance perspective. That is, a field-of-view distance under the first perspective is greater than a field-of-view distance under the second perspective (for example, an overhead angle and height of a virtual camera under the first perspective are less than an overhead angle and height of the virtual camera under the second perspective, and correspondingly, an electronic map and a navigation route are visible further under the first perspective than under the second perspective). The terminal displays the electronic map and the object identity under the first perspective by default. In a case that the distance between the object identity and the direction change node is 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, the virtual camera is controlled to move upwards on a spherical surface centered on the object identity, and the orientation of the virtual camera is aligned with the object identity to shorten the field-of-view distance, so that the navigation interface displays closer electronic maps and navigation routes more.
When the navigation perspective is switched from the first perspective to the second perspective, the attention of a user may be transferred from the far navigation route to the near navigation route, so that the user can pay attention to how to change the traveling direction in front, and the user can also view the traveling route near the change of the traveling direction in more detail by paying more attention to the near navigation route after the perspective is switched.
In an example, during the perspective switching process, the terminal still updates displaying of the electronic map based on the traveling direction, traveling speed, and the like of the navigation object.
Schematically, as shown in
In an embodiment, the display position of the object identity is adjusted upwards (or to an upper edger) in the identity display region, and increase a map scale of the electronic map.
The display position of the direction change node in the navigation interface does not change during the map scale increasing process. When the navigation perspective is switched from the first perspective to the second perspective, the terminal controls the electronic map and the object identity to move relatively at the same time so as to reduce the degree of change of the map as much as possible. The adjustment range of the object identity is within the identity display region. If the object identity has been adjusted to the edge of the identity display region, the adjustment of the display position of the object identity is stopped.
If the traveling process of the navigation object is displayed simply by moving the electronic map and adjusting the object identity, the degree of change of the electronic map is still large. Therefore, the terminal increases the map scale of the electronic map, namely, continuously enlarges the map and keeps the display position of the direction change node unchanged, so as to achieve the display effect that the object identity continuously moves to the direction change node. In the meantime, the terminal adjusts the display position of the object identity upwards, thereby reducing the enlarging speed of the map scale. Thus, the user can clearly view the traveling direction change situation at the direction change node, and the degree of change of the electronic map and the feeling of dizziness can also be reduced. In the meantime, it can be ensured that the object identity moves in the fixed visual focus region, so that the user can quickly determine the position of the vehicle.
When the terminal determines the adjustment mode as horizontal adjustment in a case that the change type of the traveling state is the traveling lane change, correspondingly, step 403 further includes the following steps:
In an embodiment, a lane change direction indicated by the traveling lane change is determined.
The terminal determines the position change situation of the navigation object through real-time positioning, and determines the lane change direction of the navigation object when it is determined that the lane where the navigation object is located is changed.
In an embodiment, the display position of the object identity is adjusted in a horizontal direction in the identity display region based on the lane change direction.
The terminal correspondingly controls the relative movement between the object identity and the map based on the lane change direction of the navigation object, namely, controls the object identity to move in the navigation interface according to the lane change direction of the navigation object, and controls the electronic map to move in the reverse direction based on the display position of the object identity, so as to achieve the display effect that the object identity changes lanes in the map. Since the display position of the object identity is adjusted, the degree of change of the electronic map can be reduced in a case of ensuring that the object identity is in the identity display range.
In a possible implementation, step 403d further includes the following steps.
In an example, to determine the horizontal adjustment mode of the object identity in the identity display region, it may be required to ensure that the horizontal adjustment mode is consistent with the lane change direction. Correspondingly, in a possible implementation, when the lane change direction is rightward lane change, the display position of the object identity in the identity display region needs to be adjusted rightwards correspondingly. When the lane change direction is leftward lane change, the display position of the object identity in the identity display region needs to be adjusted leftwards correspondingly.
In an example, the terminal first adjusts the display position of the object identity in the identity display region based on the lane change direction, and then horizontally adjusts the electronic map after the display position of the object identity cannot be further adjusted. Or, the terminal simultaneously adjusts the display position of the object identity in the identity display region and the electronic map. Thus, in a case that the lane change direction is rightward lane change, the object identity is controlled to move rightwards in the identity display region, and the electronic map is controlled to move leftwards. In a case that the lane change direction is leftward lane change, the object identity is controlled to move leftwards in the identity display region, and the electronic map is controlled to move rightwards.
In step 404, the display of the electronic map is updated based on the display position of the object identity in the identity display region being adjusted to an edge of the identity display region.
In an example, this embodiment describes an example in which the object identity is updated first and then the electronic map is updated. By updating the object identity first, the object identity is adjusted to the edge of the identity display region. By maximizing the position adjustment of the object identity, the amplitude of the subsequent adjustment of the electronic map can be reduced. In a possible implementation, displaying of the electronic map may be updated based on the display position of the object identity in the identity display region in a case that the object identity is adjusted to the edge of the identity display region.
In an example, the terminal synchronously updates displaying of the electronic map in the process of adjusting the display position of the object identity. In an example, the terminal fixedly displays the electronic map when adjusting the display position of the object identity, and updates the electronic map after adjusting the object identity to the edge of the identity display region.
In an example, the electronic map may not need to be updated if the display position of the object identity coincides with the change in the traveling state by updating the display position of the object identity.
When the adjustment mode of the object identity is vertical adjustment in a case that the change type of the traveling state is the traveling direction change, step 404 includes the following steps:
In an embodiment, the object identity is adjusted to an upper edge of the identity display region, and rotate the electronic map based on the display position of the object identity in the identity display region in a case that the map scale reaches a first scale.
The first scale is an enlarged maximum scale of the electronic map. That is, when the electronic map is enlarged to the first scale, the electronic map cannot be enlarged continuously.
When the map scale is enlarged to the first scale, the enlargement cannot be continued. At this moment, the terminal continues to move the electronic map even if the direction change node moves downwards, so as to achieve the display effect that the object identity continuously approaches the direction change node. In this process, if the object identity has moved to an upper edge of the identity display region before the map scale is enlarged to the first scale, the terminal controls the object identity to be stationary and moves the map downwards until, and moves the map when the object identity moves to the upper edge. If the object identity does not move to the upper edge, the terminal controls the object identity to move upwards while controlling the map to move downwards.
Schematically, as shown in
In order to facilitate demonstrating the change process of the electronic map and the object identity, as shown in
The object identity starts to change the traveling direction after arriving at the direction change node. At this moment, the terminal has completed the method for adjusting the object identity and scaling, so as to control the electronic map to move and rotate relative to the object identity based on the change situation of the traveling direction of the navigation object, thereby achieving the display effect that the object identity changes the traveling direction at the direction change node.
Accordingly, after the navigation object moves away from the direction change node, the terminal also needs to restore the navigation perspective and the display position of the object identity, so as to continue to observe the distant navigation route through the long-distance perspective and prepare for arriving at a next node. Therefore, after step 404, the navigation interface display method according to this embodiment of this disclosure further includes the following steps:
In a first step, the display position of the object identity is adjusted in the identity display region based on the distance between the object identity and the direction change node being greater than a second distance threshold.
In an example, after the navigation object moves away from the direction change node, in order to restore the navigation perspective and the display position of the object identity, the display position of the object identity may be adjusted in the opposite way to the previous adjustment when approaching the direction change node.
The relative movement between the electronic map and the object identity is controlled when the distance between the object identity and the direction change node is greater than the second distance threshold. In a possible implementation, step 1 further includes a step as follows:
The display position of the object identity is adjusted downwards (or is adjusted toward a lower side) in the identity display region and the map scale is reduced in a case that the distance between the object identity and the direction change node is greater than the second distance threshold.
As opposed to the adjusted display position of the object identity previously approaching the direction change node, in a possible implementation, when the terminal determines that the distance between the object identity and the direction change node is greater than the second distance threshold, it is indicated that the navigation object has completed the traveling direction change, and moves away from the direction change node. The display position of the object identity needs to be adjusted in the opposite direction. However, the object identity is adjusted upwards when previously approaching the direction change node, and the map scale is increased. The opposite operation is as follows. The terminal adjusts the display position of the object identity downwards in the identity display region and reduces the map scale, so as to embody the dynamic process of the navigation object moving away from the direction change node.
In an example, in a case that the distance between the object identity and the direction change node is greater than the second distance threshold and the distance between the object identity and a next direction change node is greater than the first distance threshold, the terminal controls the relative movement between the electronic map and the object identity. In a case that the distance between the object identity and the direction change node is greater than the second distance threshold and the distance between the object identity and the next direction change node is less than the first distance threshold, the terminal controls the object identity to be stationary at the current display position, and updates displaying of the electronic map based on the traveling direction.
In a second step, the display of the electronic map is updated based on the display position of the object identity in the identity display region and a traveling direction of the navigation object in a case that the object identity is adjusted to an edge of the identity display region.
Similar to the process of updating the object identity and the electronic map when the object identity approaches the direction change node, it is also possible to continue to update displaying of the electronic map after adjusting the display position of the object identity in the identity display region when the object identity moves away from the direction change node. Correspondingly, in a possible implementation, displaying of the electronic map may be updated based on the display position of the object identity in the identity display region and a current traveling direction of the navigation object in a case that the object identity is adjusted to the edge of the identity display region.
In a possible implementation, step 2 further includes the steps as follows:
For example, a display of the electronic map is updated based on the display position of the object identity in the identity display region and the traveling direction of the navigation object in a case that the object identity is adjusted to a lower edge of the identity display region and the map scale reaches a second scale.
The second scale is a minimum scaling multiple of the electronic map reduced by the terminal. Thus, after the electronic map is reduced to the second scale, the electronic map can no longer be reduced.
When the distance between the object identity and the direction change node is greater than the second distance threshold, the terminal first controls the object identity to move downwards in the identity display region, and also reduces the map scale so as to achieve the display effect that the object identity moves away from the direction change node. When the map scale is reduced to the second scale, the terminal controls the electronic map to move downwards. If the object identity has been adjusted to the lower edge of the identity display region at this moment, the electronic map is moved. If the object identity does not arrive at the lower edge of the identity display region, the object identity and the electronic map are controlled to move downwards simultaneously. However, the speed of relative movement therebetween is consistent with the speed of relative movement between the navigation object and an actual road (that is, the movement speed of the map is greater than the movement speed of the object identity).
In another possible implementation, when the distance between the object identity and the direction change node is greater than the second distance threshold, the terminal controls the electronic map and the object identity to move downwards. When the object identity moves to the lower edge of the identity display region, the terminal controls the object identity and the electronic map to be stationary, and gradually reduces the electronic map scale. When the map scale is reduced to the second scale, the terminal continues to move the electronic map.
In an example, in other possible implementations, the terminal may first reduce the map scale of the electronic map to the second scale, and then move the object identity downwards. When the object identity moves to the lower edge of the identity display region, the terminal continues to move the electronic map.
When the adjustment mode of the object identity is horizontal adjustment in a case that the change type of the traveling state is the traveling lane change, step 404 includes the steps as follows:
In an embodiment, the electronic map is adjusted leftwards (or to a left edge) of the navigation interface based on the display position of the object identity in a case that the lane change direction is rightward lane change and the object identity is adjusted to a right edge of the identity display region.
In a possible implementation, when the terminal determines that the lane change direction is rightward lane change, the object identity needs to move rightwards. When the object identity cannot move rightwards and the electronic map needs to be adjusted to make the object identity move rightwards, correspondingly, the electronic map needs to be adjusted reversely. That is to say, the electronic map needs to be adjusted leftwards, thereby achieving the rightward movement effect of the object identity.
In an embodiment, the electronic map is adjusted rightwards (or to an upper edge) of the navigation interface based on the display position of the object identity in a case that the lane change direction is leftward lane change and the object identity is adjusted to a left edge of the identity display region.
When the terminal determines the lane change mode of the navigation object and correspondingly adjusts the display position of the object identity, the electronic map is adjusted reversely. Compared with a position adjustment of the map or the object identity, the simultaneous reverse movement of the electronic map and the object identity can reduce the degree of change of the map and the object identity with respect to the navigation interface. When the object identity moves to the edge of the identity display region and the navigation object still continues to change lanes at this moment, the terminal stops adjusting the display position of the object identity, fixedly displays the object identity, and continues to adjust the electronic map, so that the display position of the object identity changes largely, and the user cannot quickly determine the position of the vehicle.
In an example, when the lane change direction is leftward lane change, the object identity needs to move leftwards. When the object identity has moved to the left edge, it is indicated that the object identity cannot continue to move leftwards, the electronic map needs to be adjusted to achieve the leftward movement effect of the object identity, and correspondingly, the electronic map needs to be adjusted reversely. That is to say, the electronic map needs to be adjusted rightwards, thereby achieving the leftward movement effect of the object identity.
In another possible implementation, the navigation object may have stopped lane changing when the object identity has not moved to the edge of the identity display region. Then the terminal stops adjusting the display position of the object identity and continues to update displaying of the electronic map. After step 403, the navigation interface display method according to this embodiment of this disclosure further includes the steps as follows:
For example, the object identity is displayed in a fixed position in the identity display region in a case that the object identity does not move to the edge of the identity display region and the navigation object stops lane change. A display of the electronic map is updated based on the display position of the object identity and the traveling direction of the navigation object.
The terminal adjusts the display position of the object identity based on the position change situation of the navigation object in real time. When the navigation object stops lane changing, if the object identity does not move to the edge of the identity display region, the object identity is fixedly displayed in the identity display region, and displaying of the electronic map continues to be updated based on the traveling direction of the navigation object.
In this embodiment of this disclosure, when it is determined that a navigation object is about to arrive at a direction change node, a navigation perspective is first switched from a first perspective of a long-distance view to a second perspective of a short-distance view. Then, by changing a map scale, adjusting a display position of an object identity in an identity display region and moving an electronic map, in a case of ensuring that the object identity is displayed in a fixed grid region, the degree of change of the electronic map and the feeling of dizziness of a user can be reduced, and the user can easily view the route change situation at the direction change node clearly and can change a traveling direction quickly according to a navigation route, thereby improving the driving efficiency and ensuring the safety of driving.
In a possible implementation, the terminal determines in real time, according to the geographical position of the navigation object and the navigation route, whether the traveling direction of the navigation object changes, namely, whether to control the object identity and the map to move relatively. Step 203 further includes the following sub-steps:
For example, a navigation instruction is generated based on the change situation of the traveling road in the navigation route when the traveling road in the navigation route changes. The display position of the object identity is adjusted in the identity display region and a display of the electronic map is updated in a case that the navigation object travels according to the navigation instruction and the traveling state changes.
In another possible implementation, the navigation instruction is generated by a server and transmitted to the terminal. The terminal transmits position information of the navigation object to the server in real time. The server determines, based on the position information of the navigation object and a pre-generated navigation route, whether the traveling road of the navigation object needs to be changed (namely, whether the navigation object is about to arrive at the direction change node). If yes, a navigation instruction is generated, and the navigation instruction is transmitted to the terminal. After receiving the navigation instruction, the terminal prompts the user by means of an interface or voice to change the traveling direction according to the navigation instruction. If it is detected that the navigation object travels according to the navigation instruction, the display position of the object identity is adjusted and the electronic map is updated. The interaction process between the terminal and the server is as shown in
In a possible implementation, when the traveling state of the navigation object does not change (traveling straight in a certain direction), since the relative position between the object identity and the electronic map also changes according to the fixed traveling direction, the terminal displays the traveling process of the object identity and the surrounding environment by fixing the object identity and updating the electronic map.
In step 901, an object identity of a navigation object is displayed in an identity display region, where the identity display region is a visual focus region in a navigation interface, and the object identity is displayed on an electronic map.
An exemplary implementation of step 901 is similar to that of step 201, and is not described again in this embodiment of this disclosure.
In step 902, the object identity is displayed in a fixed position in the identity display region in a case that a traveling state of the navigation object does not change, and update displaying of the electronic map based on a display position of the object identity and a traveling direction of the navigation object.
In a possible implementation, when the navigation object travels straight in a current road and the traveling state does not change, the terminal displays a traveling process of the navigation object by fixedly displaying the object identity and adjusting the electronic map. For example, when the navigation object travels in the north direction in the current lane, the terminal fixes the object identity and moves the electronic map downwards in the navigation interface.
In an example, the terminal determines a moving speed of the electronic map based on a traveling speed of the navigation object and a map scale corresponding to the map. Or, the terminal determines position information of the navigation object once every preset duration, and moves the electronic map based on the position information.
In this embodiment of this disclosure, when the traveling state of the navigation object does not change, the terminal fixedly displays the object identity. By adjusting the electronic map to achieve the display effect that the object identity moves in the electronic map, the user may determine that the object identity is displayed at the same position, so that the current position of the navigation object can be obtained from the navigation interface through a quick glance, thereby improving the efficiency of the user in determining the position and viewing the navigation route, and ensuring the safety of driving.
The various embodiments show the process in which the terminal performs the navigation interface display method in the three-dimensional map and the three-dimensional model scenario. The navigation interface display method according to this embodiment of this disclosure may also be applied to displaying a navigation interface corresponding to a two-dimensional map and a two-dimensional identity (or two-dimensional model).
The various embodiments show the process in which the terminal displays the object identity based on the identity display region and relatively moves the map and the object identity under various traveling situations of the navigation object. Since the size of the navigation interface is large and the size of the object identity is small, it is necessary to determine an appropriate identity display region so as to facilitate a user to view.
In step 1001, an identity display region is determined in a second display region.
In a possible implementation, a navigation interface includes a first display region and a second display region, the first display region and the second display region jointly display a map, a guide panel is superimposed and displayed above the map in the first display region, and the guide panel includes navigation guide information. Furthermore, basic functional controls such as a voice control and a navigation disable control are displayed in the guide panel.
The terminal determines the identity display region based on the second display region, and step 1001 further includes the following steps:
In an embodiment, the second display region can be partitioned into a plurality of grid regions.
In a possible implementation, the terminal grids the second display region or the complete navigation interface. For example, the terminal divides the second display region horizontally into m columns and vertically into n rows, generates n*m fixed grid regions, and determines one fixed grid region from the obtained n*m grid regions as the identity display region. In an illustrative example, the grid region in row 3 and column 3 may be determined as the identity display region.
In an example, the number of horizontally divided columns and the number of vertically divided rows may be dynamically changed based on the size of the second display region or the size of the complete navigation interface. If the second display region occupies the entire terminal screen, the division may be further performed according to the size of the terminal screen. If the second display region is larger, the number of columns and rows correspondingly divided is larger. If the second display region is smaller, the number of columns and rows correspondingly divided is smaller.
In an example, some users may expect a larger identity display region in order to make the size of the identity display region more consistent with user needs, for example. The terminal may determine the user needs based on a display size of a terminal font. For example, the terminal font displayed is smaller, it is indicated that the user has a better vision, and a relatively small identity display region may be set. If the terminal font displayed is larger, a relatively large identity display region may be set, so that the user can find an object representation more easily.
In an embodiment, a fixed grid region is determined in the second display region as the identity display region, where a midpoint of the fixed grid region is a golden section point of the second display region.
In a possible implementation, in order to improve the convenience of viewing the navigation interface for the user to quickly determine the position of the vehicle, the terminal determines the identity display region based on the golden section point of the second display region. For example, the terminal determines a golden section line of the second display region in the horizontal direction and a golden section line of the second display region in the vertical direction, and determines a grid region containing an intersection point of the two golden section lines as a fixed grid region. A display region corresponding to the fixed grid region is the identity display region.
Schematically, as shown in
In step 1002, an object identity of a navigation object is displayed in the identity display region.
In step 1003, a display position of the object identity is adjusted in the identity display region in a case that a traveling state of the navigation object changes.
In step 1004, a display of an electronic map is updated based on the display position of the object identity in the identity display region in a case that the display position of the object identity is adjusted.
Exemplary implementations of steps 1002 to 1004 are similar to those of the foregoing steps 201 to 203, and will not be described in detail in this embodiment of this disclosure.
In this embodiment of this disclosure, the terminal first grids the second display region of the navigation interface, determines the identity display region from each generated grid region based on the golden section, and controls the object identity to be displayed in the identity display region, thereby improving the readability of the navigation interface and the convenience of the user for viewing the position of the vehicle.

While showing the change situation of the traveling state, it can be ensured that a user determines the current position and a subsequent traveling route through a quick glance during the driving process, thereby improving the efficiency of the user in determining the position and viewing a navigation route, and ensuring the safety of driving.
