[0005] ,

[0001] (Cross - Reference to Related Applications) This application claims the priority of Chinese Patent Application No. 202310753202.2, titled "Lane Navigation Information Display Method, Device, Electronic Device, and Storage Medium", filed in China on June 25, 2023, and the entire content of the application is incorporated herein by reference.

[0002] This disclosure relates to the field of smart driving technology, and particularly to a lane navigation information display method, device, HUD system, device, and medium.

Background Art

[0003] In the prior art, usually, the lane navigation information is presented to the driver in the following two ways. The first way is to simulate the driving situation of the vehicle in the current section using a virtual vehicle, and this way can display the number of lanes and the target lane in the current section to the driver. The second way is to present the current road situation to the driver through voice guidance and an enlarged view of the intersection near the intersection, and the presentation information of this way usually has a fixed display time set in advance by the navigation system.

[0004] In the actual driving process, when the distance of some road sections is short, or when encountering sudden situations such as road congestion, traffic jams, or vehicle failures, in either of the above two ways, there is a drawback that the driver may miss the optimal timing for lane change. Therefore, how to intelligently provide intuitive and accurate lane navigation information to the driver has become an urgent problem to be solved.

Summary of the Invention

[0005] This disclosure provides a method, apparatus, HUD system, device, and medium for displaying lane navigation information, which intelligently provides intuitive and accurate lane navigation information to the driver, allowing the driver time to perform lane change operations, thereby improving driving safety and the driving experience.

[Modes for carrying out the invention]

[0016] To make the objectives, technical means, and effects of the embodiments according to the present disclosure clearer, in the following, while referring to the accompanying drawings of the embodiments of the present disclosure, the technical means according to the embodiments of the present disclosure will be clearly and completely described. As will be apparent to those skilled in the art, the embodiments described herein are only some of the embodiments of the present disclosure and do not represent all embodiments. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present disclosure without creative labor should also be included within the protection scope of the present disclosure.

[0017] It should be noted that terms such as "first", "second", "target", "original", etc. in the specification, claims, and the above-mentioned accompanying drawings of the present disclosure are used to distinguish similar objects and do not limit a specific order or sequence. Where appropriate, these terms can be used interchangeably, and it should be understood that the embodiments of the present disclosure described herein can be implemented in a form not limited to the order shown or described. Furthermore, expressions such as "comprising", "having", and their variants are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus including a series of steps or components is not necessarily limited to the explicitly listed steps or elements, and may include those not explicitly listed or other steps or elements inherent to these processes, methods, products, or apparatuses.

[0018] Embodiments of the present disclosure provide a head-up display (HUD) system. As shown in FIG. 1, the HUD system 10 includes an image generator 11, an imaging optical path component 12, and an image display component 13. The image generator 11 generates an image digital signal (i.e., a real image) and is used to convert the image digital signal into a beam of light carrying image information. In some examples, the image generator 11 is an optical engine configured using digital light processing (DLP) technology or liquid crystal on silicon (LCOS) technology, includes an illumination component and a projection component, and the projection component may be a micro projection lens. The imaging optical path component 12 reflects the real image through, for example, a mirror and projects it onto the image display component 13, so that the image display component 13 forms a visually observable virtual image screen 2 based on the light beam projected from the imaging optical path component 12. The image display component 13 can be changed according to the application scenario. For example, when the application scenario is video projection in a cinema, the image display component 13 is a projection screen or a display panel. On the other hand, when the application scenario is to display driving information on the front windshield of a vehicle, the image display component 13 may be the front windshield of the vehicle itself. In some examples, the image display component 13 is the front windshield of the vehicle and is used to display the driving information of the vehicle.

[0019] Figure 2 is a flowchart of a lane navigation information display method according to an embodiment of the present disclosure. This embodiment can be applied when an Augmented Reality Head Up Display (AR-HUD) displays the AR lane image of the current section and the next AR lane image of the next section (next road section) when it is detected that the vehicle has entered the current section (current road section). This allows the driver to grasp the lane navigation information for the current section and the next section and perform driving operations at the appropriate time. The lane navigation information display method according to this embodiment can be executed by a lane navigation information display device according to an embodiment of the present disclosure. The device is implemented by software and / or hardware and may be integrated into an electronic device that performs this method. In some examples, the electronic device according to an embodiment of the present disclosure may be the head-up display (HUD) system shown in Figure 1.

[0020] As shown in Figure 2, the method of this embodiment includes, but is not limited to, the following steps.

[0021] S210: Obtain vehicle location data and navigation route, and divide (divide) the navigation route into multiple sections.

[0022] In this disclosure, the above-mentioned segments include the current segment, the next segment, and other segments. Other segments refer to segments of the above-mentioned segments excluding the current segment and the next segment. In this embodiment, the vehicle is further equipped with a driver assistance device, which may be an Advanced Driving Assistance System (ADAS) or a map navigation system.

[0023] In embodiments of this disclosure, the HUD system further includes a processor 14, which may include a data acquisition unit, a data processing unit, and a data analysis unit. When the vehicle starts moving, the data acquisition unit can acquire vehicle position data via a map navigation system or ADAS system, and can further acquire the vehicle's navigation route via the map navigation system. The data processing unit can divide the acquired navigation route into a plurality of segments based on predetermined classification criteria and assign a segment identification number to each segment.

[0024] For example, if we assume that the interval identification number is R and the total number of intervals is n, then the interval identification numbers of multiple intervals can be represented in order as R1, R2, ..., Ri, Ri+1, ..., Rn-1, Rn, where i represents the interval index number.

[0025] Optionally, the predetermined classification criteria may be to classify a portion of the navigation route as a single section if it has the same number of lanes and all lane arrow information for each lane is identical. As shown in Figure 3, the figure schematically illustrates a method of dividing the navigation route from its starting point to its ending point into n sections based on the predetermined classification criteria. As can be seen from Figure 3, each position on the lane in each section has the same lane arrow information.

[0026] Furthermore, after dividing the navigation route into multiple sections, an AR lane image corresponding to each section is first created, thereby obtaining multiple AR lane images. Next, an image identification number is determined for each of the multiple AR lane images, and this image identification number is associated one-to-one with the section identification numbers of the multiple sections. Then, in the image display component, each AR lane image is displayed based on the initial display position and image identification number corresponding to each AR lane image.

[0027] In some examples, the initial display position may refer to the position where multiple AR lane images are first displayed when the vehicle starts moving (for example, when it enters the first section). Also, since this embodiment executes the lane navigation information display method of this disclosure when the vehicle enters the current section, the initial display position may refer to the position where multiple AR lane images are displayed when the vehicle enters the previous section. The specific method for displaying AR lane images at the initial display position and the specific method for displaying AR lane images at the target display position are generally the same, and the details will be explained in the embodiments described later.

[0028] Specifically, when creating AR lane images corresponding to each section in multiple sections, the system first acquires road information along the navigation route using a map navigation system, and then identifies lane arrow information corresponding to each section in the multiple sections from this road information. Next, based on the navigation route and lane arrow information, the system identifies the target lane that the vehicle should travel in each section. Finally, based on the lane arrow information and target lane corresponding to each section, the system generates AR lane images corresponding to each section. In the schematic diagram of the AR lane image shown in Figure 4A, there are four lanes, and the second and third lanes are shown to be the target lanes, i.e., the lanes for going straight.

[0029] In some examples, when generating AR lane images based on lane arrow information and target lanes corresponding to each section, the target lane's lane arrow information is displayed using a first display method, and the lane arrow information of the first other lanes is displayed using a second display method, thereby obtaining AR lane images corresponding to each section. Here, the first other lanes refer to lanes other than the target lane in each section. Optionally, the above display method may be a predetermined color, predetermined size, or predetermined animation. As shown in Figure 3A, an example is to display the target lane in black (first display method) and the first other lanes in gray (second display method). Note that the specific form of the display method can be customized according to user requirements, so it will not be described in detail here.

[0030] S220: When the system determines that a vehicle has entered the current section based on location data, the HUD image display component identifies the current AR lane image corresponding to the current section to be displayed (or should be displayed), the next AR lane image corresponding to the next section, and other AR lane images corresponding to other sections.

[0031] In the embodiments of this disclosure, the data analysis unit analyzes the position data acquired by the data acquisition unit in step S210 to determine the real-time location of the vehicle, i.e., whether the vehicle has entered the current section from the previous section. If it is determined that the vehicle has entered the current section, the HUD executes step S220.

[0032] In some cases, when a vehicle enters the current section, the HUD first identifies the section identification number corresponding to the current section, then identifies the section identification number of the next section based on that identification number, and finally identifies the next section corresponding to the current section. Other sections can be identified in a similar manner. Since the image identification number of an AR lane image corresponds one-to-one with the section identification number, the image identification numbers of the current AR lane image, the next AR lane image, and other AR lane images can be obtained by identifying the image identification number corresponding to the section identification number. Based on these image identification numbers, the current AR lane image, the next AR lane image, and other AR lane images can be identified from among multiple AR lane images.

[0033] When a vehicle enters the current section, the current AR lane image to be displayed on the HUD corresponds to the next AR lane image that was previously displayed on the HUD when the vehicle was traveling in the previous section. The next AR lane image to be displayed on the HUD corresponds to the AR lane image after that that was previously displayed on the HUD when the vehicle was traveling in the previous section. Other AR lane images to be displayed on the HUD can be obtained by estimation from the image identification number.

[0034] Furthermore, to more intelligently inform the driver whether or not a lane change is necessary, it is necessary to highlight the lane arrow information of the current lane in the AR lane image in order to clearly indicate which lane the vehicle is currently in.

[0035] Specifically, after identifying that a vehicle has entered the current section based on location data, the lane navigation information display method according to the embodiment of this disclosure may further include the following processing: that is, the method includes the processing of identifying the current lane of the vehicle in the current section based on location data; that is, the processing of obtaining a current AR lane image corresponding to the current section by displaying the lane arrow information of the target lane in a first display method, the lane arrow information of second and other lanes in a second display method, and the lane arrow information of the current lane in a third display method; where, second and other lanes refer to lanes other than the target lane and the current lane in the current section. Optionally, the display method may be a predetermined color, a predetermined size, or a predetermined animation. That is, different lanes can be visually distinguished and displayed using the first display method, the second display method, and the third display method. Note that the specific display method can be freely customized according to the user's requirements and will not be described in detail here.

[0036] As an example, Figure 4B shows a first schematic diagram of a current AR lane image according to an embodiment of the present disclosure. Referring to Figure 4B, there are four lanes, with the second and third lanes being the target lanes, i.e., the straight-ahead lanes. Of these, the second lane is also the current lane, and the first and fourth lanes are the second other lanes. In the figure, the second lane is shown in black with an enlarged effect, the third lane is shown in black, and the first and fourth lanes are shown in gray. As is clear from Figure 4B, the vehicle is currently traveling in the target lane, and the driver does not need to perform a lane change operation.

[0037] As a further example, Figure 4C shows a second schematic diagram of the current AR lane image according to an embodiment of the present disclosure. Referring to Figure 4C, there are similarly four lanes, with the second and third lanes being the target lanes, i.e., the straight-ahead lanes. The first lane is the current lane, i.e., the left-turn lane, and the fourth lane is the second other lane. In the figure, the second and third lanes are shown in black, the fourth lane in gray, and the first lane in gray with an enlarged effect. As is clear from Figure 4C, the vehicle is currently traveling in a non-target lane (on the first lane), and it is indicated that the driver needs to change lanes to the right and move to the second or third lane.

[0038] S230: Sets the corresponding adjustment parameters for the current AR lane image, the next AR lane image, and other AR lane images.

[0039] In the embodiments of this disclosure, when the vehicle is traveling through the previous section, the display position corresponding to the next AR lane image previously displayed on the HUD is recorded as the initial display position. When the vehicle enters the current section, the next AR lane image that was previously displayed on the HUD becomes the current AR lane image to be displayed this time. At this time, the display position corresponding to the current AR lane image to be displayed this time is recorded on the HUD as the target display position, and adjustment parameters are determined to move the AR lane image from the initial display position to the target display position.

[0040] When the vehicle is traveling through the previous section, the display position corresponding to the next-next AR lane image previously displayed on the HUD is recorded as the initial display position. When the vehicle enters the current section, the next-next AR lane image previously displayed on the HUD becomes the next AR lane image to be displayed on the HUD this time, the display position corresponding to the next AR lane image to be displayed on the HUD is recorded as the target display position, and adjustment parameters are determined to move the AR lane image from the initial display position to the target display position. By performing a similar process based on the image identification number, adjustment parameters corresponding to other AR lane images to be displayed on the HUD this time can also be obtained.

[0041] S240: Based on the adjustment parameters, the current AR lane image, the next AR lane image, and other AR lane images are adjusted to their respective target display positions, and the lane navigation information is displayed in the image display component by displaying the current AR lane image, the next AR lane image, and other AR lane images at the target display position.

[0042] In the embodiments of this disclosure, the HUD adjusts the current AR lane image, the next AR lane image, and other AR lane images to be displayed from their respective initial display positions to their respective target display positions, and displays lane navigation information at the target display positions. This helps the driver understand the current road conditions and appropriately determine whether or not to change lanes. Optionally, the image display component may be a predetermined area on the vehicle's windshield.

[0043] Considering that presenting the driver with all AR lane images corresponding to multiple sections simultaneously may interfere with driving, the system may be configured to hide or semi-transparently display other AR lane images at the target display position, clearly displaying only the current AR lane image and the next AR lane image. Furthermore, enlarging the current AR lane image can make it even clearer to distinguish it from the next AR lane image.

[0044] As an example, Figure 4D is a schematic diagram of lane navigation information according to an embodiment of the present disclosure. In Figure 4D, the first row of arrows from the bottom of the screen of the image display component shows the AR lane image of the current section, which may include the lane arrow of the current lane where the vehicle is located in the current section (attached drawing number 21), the lane arrows of all target lanes (attached drawing number 22), and the lane arrows of the second and other lanes (attached drawing number 23). The second row of arrows from the bottom shows the AR lane image of the next section, which may include the lane arrows of all target lanes in the next section (attached drawing number 31) and the lane arrows of the first and other lanes (attached drawing number 32).

[0045] According to the technical means of this embodiment, vehicle position data and navigation route are acquired, and the route is divided into multiple sections. When it is detected that the vehicle has entered the current section based on the position data, the HUD image display component identifies the current AR lane image corresponding to the current section, the next AR lane image corresponding to the next section, and other AR lane images corresponding to other sections that are to be displayed. Next, adjustment parameters corresponding to the current AR lane image, the next AR lane image, and other AR lane images are set. Based on these adjustment parameters, the current AR lane image, the next AR lane image, and other AR lane images are each adjusted to their respective target display positions, and the lane navigation information is displayed on the image display component by displaying the current AR lane image, the next AR lane image, and other AR lane images at the target display positions. In this disclosure, the AR lane images for multiple sections are identified by rationally dividing the navigation route into multiple sections based on classification criteria based on whether or not they have a similar number of lanes and whether or not the lane arrow information for each lane is the same. When a vehicle enters a section, the system identifies the current AR lane image, the next AR lane image, and other AR lane images to be displayed from among multiple AR lane images. Then, the current AR lane image, the next AR lane image, and other AR lane images are displayed at the target display position. The present invention can detect the vehicle's current section in real time, and when the vehicle enters the current section, it can immediately present the driver with AR lane images for the current section, the next section, and other sections. This allows the driver to have sufficient time to perform lane change operations, and furthermore, it can guide the driver in real time, not only presenting the driver with the number of lanes, lane arrow information, target lane, and current lane in the current section, but also notifying the driver in advance of the number of lanes, lane arrow information, and target lane in the next section. As a result, the driver can make appropriate decisions quickly even in complex road conditions, supporting efficient and safe driving. Therefore, according to this disclosure, intuitive and accurate lane navigation information can be intelligently provided to the driver, allowing time for lane change operations, and improving driving safety and the driving experience.

[0046] The following describes in more detail the lane navigation information display method according to the embodiment of this disclosure. The embodiment according to this disclosure is an optimized version based on the above-described embodiment, and specifically describes in detail the screen interaction process when displaying an AR lane image at the target display position of the image display component.

[0047] Figure 5 is a schematic diagram of a display window within an image display component according to an embodiment of the present disclosure, where Figure 5(a) is a front view of the display window, Figure 5(b) is a side view of the display window, Figure 5(c) is a perspective view of the display window, and Figure 5(d) is a top view of the display window. Within the image display component, a three-dimensional coordinate system (i.e., a right-handed coordinate system) for displaying the AR lane image is constructed. The coordinate origin of the three-dimensional coordinate system (i.e., labeled O in the figure) is the center of the bottom edge of the display window within the image display component, and is also the center of the bottom edge of the AR lane image. The X-axis is perpendicular to the Y-axis and Z-axis, respectively, and points horizontally to the left, the Y-axis is perpendicular to the ground and points upward, and the Z-axis points forward, which is the direction of vehicle travel. The dimensions of the display window are determined by the field of view at the driver's eye point. As can be seen from Figures 5(b) and 5(d), the length of the display window is 2x1 and the height of the display window is y1. The length of the display window is determined by the horizontal viewing angle at the driver's eye point, and the height of the display window is determined by the vertical viewing angle at the driver's eye point.

[0048] Other sections include the untraveled Section 1 and Section 2, which has already been traveled. Other AR lane images include the AR lane image corresponding to Section 1 and the AR lane image corresponding to Section 2. The target display position includes the first display surface, the second display surface, and the third display surface, with the first display surface being perpendicular to the second and third display surfaces, respectively, and the second display surface being parallel to the third display surface. The upper boundary of the first display surface overlaps with the lower boundary of the second display surface, and the lower boundary of the first display surface overlaps with the upper boundary of the third display surface.

[0049] Figure 6A is a schematic diagram showing the positional relationship between the first display surface, the second display surface, and the third display surface at the target display position according to an embodiment of the present disclosure. Referring to Figure 6A, with reference to the three-dimensional coordinate system, the first display surface 1 is parallel to the XOY plane, and the center point of the lower boundary of the first display surface is located at the coordinate origin of the XOY plane. Both the second display surface 2 and the third display surface 3 are parallel to the XOZ plane, and the Y-axis coordinate of the second display surface 2 is h. That is, the height of the AR lane image is h, and the center point of the upper boundary of the third display surface 3 is located at the origin of the XOZ plane.

[0050] The first display surface 1 is used to display the current AR lane image that is scheduled to be displayed. The second display surface 2 is used to display the next AR lane image and the first AR lane image that are scheduled to be displayed, and the third display surface 3 is used to display the second AR lane image that is scheduled to be displayed. On the second display surface 2, the next AR lane image and the first AR lane image are displayed sequentially overlaid or unfolded according to the image identification number. On the third display surface 3, the second AR lane images are displayed sequentially overlaid or unfolded according to the image identification number.

[0051] Figure 6B is a schematic diagram showing an example of another AR lane image according to an embodiment of the present disclosure. Referring to Figure 6B, the current section is Ra, and the position of the center point Qa of the current AR lane image on the first display surface 1 in Figure 6B is Position(xa,ya,za)=(0,h / 2,0), and it is positioned parallel to the XOY plane. When viewed from the driver's viewpoint, it has the effect of a front view and does not have a perspective distortion effect. The next section is Ra+1, and the position of the center point Qa+1 of the next AR lane image on the second display surface in Figure 6B is Position(xa+1,ya+1,za+1)=(0,h,h / 2), and it is parallel to the XOZ plane. When viewed from the driver's viewpoint, it has the effect of an overhead view (top view) and has a perspective distortion effect. Furthermore, if the first section is denoted as Ra+2, Ra+3, ..., Rn, then the first AR lane image on the second display surface in Figure 6B has a coordinate h on the Y axis, is parallel to the XOZ plane, and extends along the positive Z axis. Therefore, the positions of the center points Qa+2, Qa+3, ..., Qn of the first AR lane image in the coordinate system are as follows: Position(xa+2,ya+2,za+2)=(0,h,3h / 2), Position(xa+3,ya+3,za+3)=(0,h,5h / 2), ..., Position(xn,yn,zn)=(0,h,([2(na)-1]h) / 2). If the second section is denoted as Ra-1, Ra-2, ..., R1, then the second AR lane image in the third display plane of Figure 6B has a coordinate of 0 on the Y axis, is parallel to the XOZ plane, and is positioned extending along the positive Z axis. Therefore, the positions of each center point Qa-1, Qa-2, ..., Q1 of the second AR lane image in the coordinate system are as follows: Position(xa-1,ya-1,za-1)=(0,0,h / 2), Position(xa-2,ya-2,za-2)=(0,0,3h / 2), ..., Position(x1,y1,z1)=(0,0,([2(na)-1]h) / 2).

[0052] Figure 6C is a schematic diagram showing another example of the display of AR lane images according to the embodiment of this disclosure. The arrangement of the current AR lane image on the first display surface and the next AR lane image on the second display surface is the same as the arrangement in Figure 6B. If the first section is Ra+2, Ra+3, ..., Rn, then the first AR lane image on the second display surface in Figure 6C has a coordinate h on the Y axis, is parallel to the XOZ plane, and is displayed superimposed from top to bottom in the order of the image identification numbers at the position indicated by reference numeral 9 in the attached drawings. The position of the center point Qa+2, Qa+3, ..., Qn of the first AR lane image on the coordinate system is Position(xa+2,ya+2,za+2)=Position(xa+3,ya+3,za+3)=...=Position(xn,yn,zn)=(0,h,h / 2). If the second section is denoted as Ra-1, Ra-2, ..., R1, then the second AR lane image on the third display surface in the figure has a coordinate of 0 on the Y axis, is parallel to the XOZ plane, and is displayed superimposed from top to bottom in the order of image identification numbers at the position of attached drawing reference numeral 10. The position of the center point Qa-1, Qa-2, ..., Q1 of the second AR lane image on the coordinate system is Position(xa-1,ya-1,za-1)=Position(xa-2,ya-2,za-2)=...=Position(x1,y1,z1)=(0,0,h / 2).

[0053] The following describes the specific process by which, when a vehicle enters the current section, the HUD adjusts the current AR lane image, the next AR lane image, and other AR lane images to their respective target display positions based on adjustment parameters, and displays the current AR lane image, the next AR lane image, and other AR lane images at the target display positions, thereby displaying lane navigation information on the image display component.

[0054] As the first method, the specific process for adjusting each AR lane image to its corresponding target display position includes the following steps.

[0055] The adjustment parameters include the virtual rotation axis, rotation direction, rotation coordinates, translation direction, and translation coordinates, and these adjustment parameters are relative to the center point Q of the AR lane image. As shown in Figure 6B, reference numeral 1 indicates the first display surface for displaying the current AR lane image. Reference numeral 2 indicates the second display surface for displaying the next AR lane image. Reference numeral 3 indicates the second display surface for displaying the first AR lane image. Reference numeral 4 indicates the third display surface for displaying the AR lane image of the previous section. Reference numeral 5 indicates the third display surface for the second AR lane image other than the AR lane image of the previous section. Reference numeral 6 indicates the rotation direction of the first display surface 1, the second display surface 2, and the third display surface 4, and is for explaining the rotation animation and is not displayed on the actual screen. Reference numeral 7 in the attached drawing indicates a virtual rotation axis used for the rotation transformation of the first display surface 1, the second display surface 2, and the third display surface 4. It passes through point F(0,h / 2,h / 2), is parallel to the X-axis, and is shown for illustrative purposes only; it does not exist on the actual HUD image plane. Reference numeral 8 in the attached drawing indicates the direction of translation of the first AR lane image corresponding to the first section. This is also for illustrative purposes of the rotation animation and does not exist on the actual screen.

[0056] When displaying AR lane images on the second and third display surfaces according to the image identification number (i.e., the display method for other AR lane images in Figure 6B), the following processing is performed to adjust the current AR lane image, the next AR lane image, and other AR lane images to their respective target display positions based on the adjustment parameters. First, the current AR lane image to be displayed is set to the first rotation coordinate (for example, Rotation(xa,ya,za)=(90,0,0)) along the virtual rotation axis (attached drawing reference numeral 7 in Figure 6B) and rotation direction (direction indicated by attached drawing reference numeral 6). The current AR lane image is rotated according to the rotation, moving from the second display surface to the first display surface. Next, based on the first translation direction (the direction indicated by reference numeral 8 in the attached drawing in Figure 6B), the next AR lane image to be displayed and the first AR lane image to be displayed are translated to the first translation coordinate (for example, translated by a distance h in the negative Z-axis direction), thereby moving the next AR lane image to be displayed and the first AR lane image to be displayed on the second display surface from their respective initial display positions to their target display positions. Subsequently, the previously displayed current AR lane image is rotated along the virtual rotation axis and rotation direction according to the second rotation coordinate (for example, Rotation(xa-1,ya-1,za-1)=(0,0,0)), and the previous The currently displayed AR lane image is rotated and moved from the first display plane to the third display plane. Finally, based on the second translation direction (the direction opposite to the direction indicated by reference numeral 8 in the attached drawing in Figure 6B), the previously displayed second AR lane image is translated to the second translation coordinate (for example, translated by a distance h in the positive Z-axis direction), thereby moving each of the previously displayed second AR lane images on the third display plane from their respective initial display positions to their target display positions. Here, the currently displayed AR lane image corresponds to the previously displayed next AR lane image, the previously displayed next AR lane image corresponds to one of the previously displayed first AR lane images, and the previously displayed current AR lane image corresponds to one of the previously displayed second AR lane images.

[0057] As a second method, the specific process for adjusting each AR lane image to its corresponding target display position includes the following steps.

[0058] The adjustment parameters include the virtual rotation axis, rotation direction, and rotation coordinates, and these adjustment parameters are based on the center point Q of the AR lane image. As shown in Figure 6C, the difference from Figure 6B is that attached reference numeral 9 indicates a second display surface for displaying the first AR lane image, and attached reference numeral 10 indicates a third display surface for displaying the second AR lane image.

[0059] When displaying AR lane images on the second and third display surfaces based on image identification numbers (i.e., the display method for other AR lane images shown in Figure 6C), adjusting the current AR lane image, the next AR lane image, and other AR lane images to their respective target display positions based on adjustment parameters includes the following process. The difference from the method in Figure 6B is that, based on the first translation direction (the direction indicated by attached drawing reference numeral 8 in Figure 6B), the next AR lane image to be displayed is moved to the first translation coordinate (i.e., translated by a distance h in the negative Z-axis direction), thereby moving the next AR lane image to be displayed on the second display surface from its corresponding initial display position to the target display position. With this method, it is not necessary to perform a translation operation on the previously displayed second AR lane image.

[0060] Next, we will explain the specific process of displaying lane navigation information on the image display component by displaying the current AR lane image, the next AR lane image, and other AR lane images at the target display position.

[0061] The process of displaying the current AR lane image, the next AR lane image, and other AR lane images at the target display position includes the following steps: The transparency parameter (T1) corresponding to the first display surface is set as the first parameter, the transparency parameter (T2) corresponding to the second display surface is set as the second parameter, and the transparency parameter (T3) corresponding to the third display surface is set as the third parameter. Here, the first parameter is greater than the second parameter, and the second parameter is greater than the third parameter. The current AR lane image is displayed on the first display surface based on the first parameter, the next AR lane image is displayed on the second display surface based on the second parameter, the first AR lane image is displayed on the second display surface based on the third parameter, and the second AR lane image is displayed on the third display surface based on the third parameter. This makes it possible to display the current AR lane image, the next AR lane image, and other AR lane images on the image display component with a three-dimensional perspective effect.

[0062] Optionally, the transparency parameters may be set as follows: first parameter T1=1 (i.e., fully display the current AR lane image), second parameter T2=0.6 (i.e., partially display the next AR lane image), and third parameter T3=0 (i.e., hide the other AR lane images).

[0063] As an example of actual application, Figure 7 is a schematic diagram of a rotation animation showing the transition from the previously displayed AR lane image to the AR lane image to be displayed this time. Figure 7(a) shows the previously displayed AR lane image, and Figure 7(b) shows the AR lane image to be displayed this time.

[0064] The navigation route is divided into six sections, namely R1, R2, ..., R6. When the vehicle is traveling through section R2, the AR lane image for section R2 is displayed on the first display screen. Its position parameters are as follows: Position(x2,y2,z2)=(0,h / 2,0), Rotation(x2,y2,z2)=(90,0,0), T1=1. The AR lane image for section R3 is displayed on the second display screen, and its position parameters are as follows: Position(x3,y3,z3)=(0,h,h / 2), Rotation(x3,y3,z3)=(0,0,0), T2=0.6.

[0065] When the vehicle enters section R3, the system performs calculations and comparisons using position data and map data acquired by the map navigation system, generates an animation trigger signal, starts the rotation animation, and executes the following three-part operation.

[0066] The first part is the process by which the currently displayed AR lane image fades out from the first display surface. Specifically, the AR lane image of section R2 rotates at a constant speed along the virtual rotation axis 7 and in the rotation direction 6 from the first display surface to the third display surface, gradually disappearing. At this time, the position parameter of the AR lane image of section R2 changes from Position(x2,y2,z2):(0,h / 2,0)→(0,0,h / 2), Rotation(x2,y2,z2):(90,0,0)→(0,0,0), and the transparency parameter changes from T1=1→T3=0.

[0067] The second part describes the process in which the previously displayed next AR lane image becomes the current AR lane image to be displayed. The AR lane image in section R3 rotates at a constant speed from the second display surface to the first display surface along the virtual rotation axis 7 and in the rotation direction 6. At this time, the position parameter of the AR lane image in section R3 changes from Position(x3,y3,z3):(0,h,h / 2)→(0,h / 2,0), Rotation(x3,y3,z3):(0,0,0)→(90,0,0), and the transparency parameter changes from T2=0.6→T1=1.

[0068] The third part describes the process by which the next AR lane image, which is scheduled to be displayed, gradually appears on the second display surface from a hidden state. The AR lane image for section R4 moves at a constant speed along the negative Z-axis from the position of reference numeral 31 in the attached drawing to the position of reference numeral 2 in the attached drawing. At this time, the position parameter of the AR lane image for section R4 changes from Position(x4,y4,z4):(0,h,3h / 2)→(0,h,h / 2), Rotation(x4,y4,z4) does not change, and the transparency parameter changes from T2=0→T2=0.6.

[0069] In the HUD image display component, the screen displayed at the start of the rotation animation is a schematic diagram of the lane navigation information shown in Figure 7(a), and the screen displayed at the end of the rotation animation is a schematic diagram of the lane navigation information shown in Figure 7(b).

[0070] Figure 8 is a schematic diagram showing the configuration of a lane navigation information display device according to an embodiment of the present disclosure, the device being integrated into a HUD. As shown in Figure 8, the device 800 may include the following components.

[0071] The segment division module 810 acquires vehicle position data and navigation route, and is used to divide the navigation route into multiple segments. These multiple segments include the current segment, the next segment, and other segments, with other segments being those segments excluding the current segment and the next segment.

[0072] The display image identification module 820 is used to identify the current AR lane image corresponding to the current section, the next AR lane image corresponding to the next section, and other AR lane images corresponding to other sections, respectively, in the HUD's image display component when it is determined that a vehicle has entered the current section based on location data.

[0073] The adjustment parameter identification module 830 is used to set the adjustment parameters corresponding to the current AR lane image, the next AR lane image, and other AR lane images, respectively.

[0074] The navigation information display module 840 is used to present lane navigation information on an image display component by adjusting the current AR lane image, the next AR lane image, and the other AR lane images to their respective target display positions based on adjustment parameters, and displaying the current AR lane image, the next AR lane image, and the other AR lane images at the target display positions.

[0075] Furthermore, the navigation information display module 840 may include an initial image display unit and a target image display unit.

[0076] The initial image display unit described above is used to obtain multiple AR lane images by dividing the navigation route into multiple sections, generating an AR lane image corresponding to each of the multiple sections, and obtaining multiple AR lane images. An image identification number corresponding to the multiple AR lane images is identified, and this image identification number corresponds one-to-one with the section identification number of the multiple sections. In the image display component described above, each AR lane image is displayed based on the initial display position and the image identification number corresponding to each AR lane image.

[0077] Furthermore, the initial image display unit may include a lane image generation subunit.

[0078] The lane image generation subunit identifies lane arrow information corresponding to each of the multiple sections. Based on the navigation route and the lane arrow information, it identifies the target lane that the vehicle should travel in each section. Based on the lane arrow information and target lane corresponding to each section, it is used to generate an AR lane image corresponding to each section.

[0079] Furthermore, the display image identification module 820 may be configured as follows: It may be used to identify the other section by identifying the next section corresponding to the current section based on the section identification number. It may be used to identify the image identification number corresponding to the section identification number. It may be used to identify the current AR lane image, the next AR lane image, and the other AR lane image from among the multiple AR lane images based on the image identification number.

[0080] Furthermore, the lane image generation subunit may be configured as follows: The lane arrow information of the target lane is displayed using a first display method, and the lane arrow information of the first other lanes is displayed using a second display method to obtain an AR lane image corresponding to each section. Here, the first other lanes refer to lanes other than the target lane in each section.

[0081] Furthermore, the lane image generation subunit may be further configured as follows: It may be used to identify the current lane (which lane the vehicle is traveling in) within the current section based on the position data after the vehicle has entered the current section based on the position data. It may also be used to obtain a current AR lane image corresponding to the current section by displaying the lane arrow information of the target lane using the first display method, the lane arrow information of the second and other lanes using the second display method, and the lane arrow information of the current lane using the third display method. Here, the second and other lanes refer to lanes other than the target lane and the current lane in the current section.

[0082] Optionally, the above "other sections" include the untraveled first section and the already traveled second section. The above "other AR lane images" also include the first AR lane image corresponding to the first section and the second AR lane image corresponding to the second section. The above "target display position" includes the first display surface, the second display surface and the third display surface, with the first display surface being perpendicular to the second and third display surfaces respectively, and the second display surface being parallel to the third display surface. The upper boundary of the first display surface overlaps with the lower boundary of the second display surface, and the lower boundary of the first display surface overlaps with the upper boundary of the third display surface.

[0083] Optionally, the first display surface is used to display the current AR lane image to be displayed, the second display surface is used to display the next AR lane image and the first AR lane image to be displayed, and the third display surface is used to display the second AR lane image to be displayed. On the second display surface, the next AR lane image and the first AR lane image can be displayed sequentially overlaid or unfolded based on the image identification number, and on the third display surface, the second AR lane image can be displayed sequentially overlaid or unfolded based on the image identification number.

[0084] Furthermore, the target image display unit may be configured as follows: It may be used to set the transmittance parameter corresponding to the first display surface as the first parameter, the transmittance parameter corresponding to the second display surface as the second parameter, and the transmittance parameter corresponding to the third display surface as the third parameter. The first parameter is greater than the second parameter, and the second parameter is greater than the third parameter. The first display surface may be used to display the current AR lane image based on the first parameter, the second display surface may be used to display the next AR lane image based on the second parameter, and the third display surface may be used to display other AR lane images based on the third parameter. This makes it possible to display the current AR lane image, the next AR lane image, and other AR lane images on the image display component with a three-dimensional perspective effect.

[0085] Optionally, the above adjustment parameters may include at least one of the following: virtual rotation axis, rotation direction, rotation coordinate, translation direction, and translation coordinate.

[0086] Furthermore, the target image display unit may be configured as follows: When displaying an AR lane image on the second and third display surfaces based on the image identification number, the current AR lane image to be displayed may be rotated in a first rotation coordinate along the virtual rotation axis and the rotation direction, thereby used to rotate and move the current AR lane image from the second display surface to the first display surface. The next AR lane image to be displayed and the first AR lane image to be displayed may be translated in a first translation coordinate based on the first translation direction, thereby used to move the next AR lane image to be displayed and the first AR lane image to be displayed from their respective initial display positions to the target display positions on the second display surface. Furthermore, the previously displayed current AR lane image may be rotated in a second rotation coordinate along the virtual rotation axis and the rotation direction, thereby used to rotate and move the previously displayed current AR lane image from the first display surface to the third display surface. In addition, based on the second translation direction, the previously displayed second AR lane image is translated in the second translation coordinates, thereby moving the previously displayed second AR lane image from its initial display position to its target display position on the third display surface. Here, the current AR lane image to be displayed corresponds to the previously displayed next AR lane image, the previously displayed next AR lane image corresponds to one of the previously displayed first AR lane images, and the previously displayed current AR lane image corresponds to one of the previously displayed second AR lane images.
