DETAILED DESCRIPTION

[0019] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0020] AR-HUD is a type of head-up display. Through its special optical imaging principle, it displays a virtual image in front of the driver. The imaging distance of AR-HUD can reach 5-7.5 meters, so that the virtual image can be superimposed on objects or real road scenes 20 meters away, forming an augmented reality effect, allowing the driver to observe the real environment while obtaining prompt information.

[0021] During the driving process, if the road is congested due to road maintenance, traffic accidents, vehicle breakdowns, etc., the AR-HUD will generally display a small map or guide arrows to show the driver the driving route. However, when congestion occurs, the AR-HUD will not prompt the congestion, resulting in the driver being unable to make preparatory actions based on the congestion, affecting the driving experience.

[0022] The image display method provided in the present application generates display content according to target information content and display features, and sets the display content to move along a predetermined track on a projection surface, so as to specifically prompt the driver of the road congestion ahead and enhance the driving experience.

[0023] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0024] Figure 1 Schematic diagram of the image processing method provided in this application Figure 1 The image processing method provided in the embodiment of the present application is applied to a head-up display, such as Figure 1 As shown, the method includes: S101. Acquire target information, where the target information includes target information content and target information type.

[0025] Preferably, the target information is obtained from the navigation software of the terminal, and the target information is information related to traffic jams. The information content related to road congestion and the type of the information are obtained from the navigation software. For example, navigation information is obtained from the navigation software of the vehicle's central control screen. When the driver is navigating and driving, if there is road congestion ahead, the navigation software generates congestion information based on the road congestion situation. The target information content is specific display content, such as "congestion ahead XX meters, congestion distance XX meters, congestion duration 20 minutes".

[0026] S102: Acquire display characteristics of information currently displayed by the head-up display, and determine display characteristics of target information.

[0027] When displaying images based on AR HUD, each layer of images is displayed by drawing layers. At this time, the upper layer image will block the lower layer image when displayed. In this method, the display feature is the display depth of the image. The display depth of the target information is determined according to the display depth of the current display information. The display depth of the current display information is preset by the program.

[0028] S103: Determine a target information display mode according to the target information content and the display characteristics of the target information.

[0029] Preferably, after obtaining the target information content and the display depth of the target information, the content to be displayed and its display depth, ie, the display mode of the target information, are generated accordingly.

[0030] S104. Displaying target information content on the projection surface according to a display mode, wherein the target information content moves along a predetermined track.

[0031] Preferably, the projection surface is a car windshield. According to the currently acquired target information display mode, the target information content is displayed on the windshield.

[0032] Furthermore, at least one predetermined track is provided on the projection surface, and the predetermined track can be arranged horizontally, vertically, or obliquely, and the user can select the setting according to his / her own situation.

[0033] Furthermore, a predetermined direction needs to be set, and the target information content needs to move along the predetermined track while moving along the predetermined direction. For example, when the predetermined track is set to be parallel to the horizontal direction, the predetermined direction can be set to be from left to right, or from right to left, or from the middle to both sides, or from the middle to either side.

[0034] Furthermore, the target information content is moved according to a preset moving distance and a predetermined moving direction, and can be moved simultaneously or after an interval.

[0035] For example, if the target information content is "800 meters ahead, traffic jam", and the moving distance is set to N characters, and the setting needs to move simultaneously, then at this time, each character in "XX meters ahead, traffic jam" moves N character distances along the predetermined track and predetermined direction at the first moment, and moves one character distance at the second moment, until the target information content disappears. The second moment is after the first moment, and N is a positive integer.

[0036] For example, the target information content is "congestion XX meters ahead", when the moving distance is set to N characters, and the next character is set to move after a first time interval, then at this time, the "front" character moves N characters along the predetermined direction of the predetermined track, and after the first time interval, the "side" character moves N characters along the predetermined direction of the predetermined track, and subsequent characters move in this way in sequence.

[0037] Figure 2 Schematic diagram of the image processing method provided in this application Figure 2 .like Figure 2 As shown, the image processing method provided in the embodiment of the present application, before acquiring the target information, the method further includes: S201: Determine whether the user turns on the navigation function.

[0038] In this embodiment, the target information is information related to traffic jams. If the traffic jam information is to be displayed, it needs to be obtained from the navigation software, that is, the car navigation function needs to be turned on at this time, so that the head-up display can obtain the required target information from the navigation software.

[0039] S202: If the user turns on the navigation function, the target information in the navigation software is obtained at a preset time interval.

[0040] In this application, if the user turns on the navigation function, the navigation software is in working state. In order to receive the target information in time, the time interval is preset in advance, and the head-up display obtains the target information from the navigation software according to the preset time interval.

[0041] In one implementation, the target information types include first type target information and second type target information; wherein the first type target information includes road ahead information and prediction information obtained from map software; and the second type target information includes feedback information from map users on the road ahead obtained from map software.

[0042] For example, the congestion information in the existing navigation software includes the distance between the congested road and the user's location, the length of the congested road, the cause of the congestion, the predicted congestion duration, and the congestion comments fed back by other users. The above concentrated congestion information is divided into the first type of target information and the second type of target information. The first type of target information includes the distance between the congested road and the user's location, the length of the congested road, the cause of the congestion, and the predicted congestion duration; the second type of target information includes the congestion comments fed back by other navigation software users. In this way, the basic situation of congestion is understood by using the first type of target information, and the congestion comments of navigation software users in the second type of target information are used to further understand the specific situation of congestion and increase the interaction between users.

[0043] In one implementation, the method further includes: At least one predetermined track is set in the first display area; the predetermined track is used to move and display the target information content.

[0044] Preferably, when the target information includes first type target information and second type target information, the predetermined tracks for the two types of information to move can be set to the same track, and the first type target information is displayed first, and then the second type target information is displayed.

[0045] Figure 3 Schematic diagram of the image display interface provided for this application Figure 1 ,like Figure 3 As shown, the first type of target information 301 moves along the X direction on the predetermined track 303 first, and the second type of target information 302 moves along the X direction on the predetermined track 303 later. In this embodiment, the predetermined track 303 is drawn and displayed to show it. In actual use, the predetermined track 303 may not be displayed. Of course, the first type of target information and the second type of target information can also be superimposed to form a whole information, and move along the predetermined track at the same time. Figure 4 Schematic diagram of the image display interface provided for this application Figure 2 ,like Figure 4 As shown, the first type of target information 401 is arranged below the second type of target information 402, and the first type of target information 401 and the second type of target information 402 are superimposed to form an integrated information and move along the X direction on the predetermined track 403. In order to show the predetermined track 404 and the superimposed effect, the predetermined track 404 and the superimposed frame of the first type of target information 401 and the second type of target information 402 are drawn and displayed in this embodiment. In actual use, the superimposed frame of the predetermined track 404 and the first type of target information 401 and the second type of target information 402 may not be displayed. Further, the graphic size of the first type of target information 401 may be greater than or equal to the graphic size of the second type of target information 402.

[0046] Furthermore, the predetermined tracks for the movement of the two types of information can be set separately, that is, the first type of target information moves along a first predetermined track, and the second type of target information moves along a second predetermined track, wherein the first predetermined track and the second predetermined track are different, at least one first predetermined track can be set, and multiple second predetermined tracks can be set.

[0047] Figure 5 Schematic diagram of the image display interface provided for this application Figure 3 ,like Figure 5 As shown, the first predetermined track 501 is set above the second predetermined track 502. At this time, since the first type of target information and the second type of target information respectively set predetermined tracks, the moving direction of the first type of target information and the moving direction of the second type of target information can be the same or different, which can be set by program according to user needs.

[0048] Figure 6 Schematic diagram of the image processing method provided in this application Figure 3 .like Figure 6 As shown, the image processing method provided in the embodiment of the present application obtains the display characteristics of the current display information of the head-up display, determines the display characteristics of the target information, and further includes: S601. Obtain the type of information currently displayed on the head-up display.

[0049] Preferably, the head-up display includes multiple types of information, generally including instrument-related information, navigation guide arrows, and some head-up displays also include small maps, vehicle driving status model diagrams, etc. Before displaying the target information, the current display information type needs to be obtained first.

[0050] S602: Obtain display characteristics of the current display information according to the type of the current display information.

[0051] Preferably, each display information has a preset display feature, that is, each display information has its corresponding display depth, and the display depth of each display information is obtained according to the current display information type.

[0052] S603: Determine display characteristics of target information according to a preset level.

[0053] Preferably, the priorities of the target information and different types of display information are preset in advance, and the display depth of the target information is determined according to the preset levels, so that the display of the target information will not block the display of important information.

[0054] Specifically, when the priority of the navigation guide arrow is preset to be greater than the priority of the target information, then the depth value of the target information should be greater than the depth value of the navigation guide arrow, that is, the display of the target information will not block the navigation guide arrow. If there is information in the current display information that sets the disabled depth writing function, then the information that disables the depth writing function has the highest priority, that is, all other information cannot block the information that disables the depth writing function.

[0055] For example, the currently displayed content includes vehicle speed information, navigation guide arrows, and collision warning information. According to preset conditions, the priority of the vehicle speed information is lower than that of the navigation guide arrow, and the collision warning information is set to disable the depth writing function. If the priority of the target information is set to be greater than the vehicle speed information and less than the navigation guide arrow, then at this time, the display depth of the target information is less than the display depth of the vehicle speed information and greater than the display depth of the navigation guide arrow, that is, the current display mode is: the collision warning information has no image occlusion and is the highest level; followed by the navigation guide arrow; then the target information of this embodiment; and finally the vehicle speed information, thereby forming a display mode for the target information.

[0056] Figure 7 Schematic diagram of the image processing method provided in this application Figure 4 .like Figure 7 As shown, the image processing method provided in the embodiment of the present application further includes: S701. Preset a first display area, where the first display area is used to display the target information; wherein the first display area is not larger than a head-up display display area.

[0057] Preferably, the first display area may be a regular area or an irregular area.

[0058] Figure 8 Schematic diagram of the image display interface provided for this application Figure 4 ,like Figure 8 As shown, the first display area 801 is a rectangular area, and the target information content is displayed and moved in the first display area 801. In this embodiment, the first display area 801 is drawn and displayed in order to show it. In actual use, the outer frame of the first display area 801 may not be displayed.

[0059] Furthermore, at least one predetermined track 802 is also set in the first display area 801, that is, the target display information content moves along a predetermined track 802 in the first display area 801. Thus, the influence of the display of the target information content on the display of other images is reduced.

[0060] In one implementation, the method further includes: When the target information content moves along a predetermined track, the target information content changes display form according to a preset dynamic effect.

[0061] Preferably, the preset dynamic effect includes one or more of color change, size change, and transparency change. For example, the preset dynamic effect includes both size change and transparency change. The color change is a change from the currently displayed first color to other colors; the size change is a change from the currently displayed first size to other sizes, which may be larger or smaller than the first size; the transparency change is a change from the currently displayed first transparency to other transparency, which may be larger or smaller than the first transparency.

[0062] For example, when the preset dynamic effect is color change, the color of the target information content display can be set to change from the currently displayed green to blue. When the preset dynamic effect is transparency change, the transparency of the target information content display can be set to gradually decrease from a relatively high transparency, that is, the target information content display can gradually deepen from a shallow one.

[0063] For another example, when the preset dynamic effects are size change and transparency change, the size of the target information content may change from small to large, and the transparency may gradually increase from shallow to deep during the movement.

[0064] Furthermore, the transformation of the preset dynamic effect can be set to be transformed once, or can be set to be transformed multiple times.

[0065] For example, the preset dynamic effect is color change, which can be set to change from green to blue, then from blue to red; or from blue to green.
