[0058] To enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0059] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar first objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein.

On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0060] Please refer to Figure 1 , Figure 1 It is a schematic diagram of an application scenario of a head-up display device provided by an embodiment of the present disclosure. The head-up display device (Head Up Display, HUD) can be used in an automobile as a driving assistance instrument. The HUD can project vehicle speed, navigation information, warning information, etc. in the form of images and characters onto the front of the driver through an optical component, forming a virtual image in front of the driver's line of sight.

[0061] Currently, when analyzing the imaging effect of a HUD, the analysis process is relatively complex and cumbersome. Based on this, the embodiments of the present disclosure provide a visualization analysis method for analyzing the imaging effect of a HUD. This method can present the imaging effect of the HUD in a relatively intuitive manner, so as to quickly make a preliminary judgment on the quality of the imaging effect, and can quickly and effectively analyze the imaging effect of the HUD in the early stage of design, which plays an important role in improving and enhancing the imaging effect of the HUD.

[0062] The following will introduce a specific embodiment of a visualization analysis method for a head-up display device provided by this application. This method can be implemented on a terminal device. Figure 2 is a flowchart of a visualization analysis method for a head-up display device shown according to an exemplary embodiment, as Figure 2 shown, the visualization analysis method for a head-up display device may include the following steps:

[0063] S201: Obtain a three-dimensional virtual model of the head-up display system.

[0064] In the embodiments of the present disclosure, when analyzing the imaging effect of a head-up display device, the terminal device first needs to model the head-up display system in which the head-up display device (HUD) is located. During the modeling process, a three-dimensional virtual model of the head-up display system is established based on the actual structure of the head-up display system. Generally, the head-up display system includes a HUD and an imaging component. The HUD includes an image source module and a mirror component. The image source module is used to generate an image. The image generated by the image source module is reflected by the mirror component to the imaging component, and then forms a virtual image in the imaging plane after being reflected by the imaging component. When the HUD is applied to a vehicle such as Figure 1 shown in a car or other vehicle, the imaging component can be the front windshield.

[0065] In some possible embodiments, the above image source module includes a display panel and a light source; the terminal device uses a modeling tool to construct a three-dimensional virtual model of the head-up display system. The three-dimensional virtual model includes an optical structure model and a virtual light source; among them, the optical structure model is generated by an optical design tool, and the virtual light source is drawn by a three-dimensional drawing tool; by simulating the emission of test light rays by the virtual light source, the test light rays form a test light path through the optical structure model, and finally form a test virtual image in the imaging plane to perform imaging effect analysis;

[0066] Specifically, the above step S201 of obtaining a three-dimensional virtual model of the head-up display system may include the following steps as Figure 3 shown:

[0067] S301: Based on the optical structure parameters of the image source module, the optical structure parameters of the mirror assembly, and the optical structure parameters of the imaging assembly, use an optical design tool to generate an optical structure model.

[0068] As Figure 4 shown, Figure 4 is a schematic diagram of an optical structure model provided by an embodiment of the present disclosure; in step S301, the terminal device first obtains the optical structure parameters of the image source module, the optical structure parameters of the mirror assembly, and the optical structure parameters of the imaging assembly, and then uses an optical design tool to generate an optical structure model; wherein, the optical structure parameters of the image source module may include the structural parameters of the light source, the refractive index and curvature of the display panel, etc., the optical structure parameters of the mirror assembly may include the approximate curvature and optical path of the curved mirror, etc., and the optical structure parameters of the imaging assembly may include the refractive index, curvature, etc. of the windshield; the optical design tool may be CODE V software, and correspondingly, the optical structure model is stored in the form of a codev file. CODE V is a world-class optical design software that helps developers quickly design optical solutions with its intuitive and intelligent tools.

[0069] Among them, the optical structure model includes a display panel structure model corresponding to the display panel. As Figure 5 shown, Figure 5 is a schematic diagram of a display panel structure model provided by an embodiment of the present disclosure, and the optical structure model further includes a light-emitting point formed by the light emitted by the light source on the display panel structure model.

[0070] S303: Use a 3D drawing tool to draw a virtual light source on the display panel structure model based on the light-emitting point.

[0071] In step S303, the terminal device uses a 3D drawing tool to load the optical structure model and draw a virtual light source at the corresponding position of the light-emitting point on the display panel structure model. Among them, the 3D drawing tool may be CATIA software. CATIA software can provide 3D design and simulation solutions in fields such as automotive, aerospace, and shipbuilding.

[0072] In a specific example, the light source is a light source array of a preset size, and the preset size may be 11*11; correspondingly, the virtual light source is a virtual light source array of this preset size; then, step S303 may specifically include using a 3D drawing tool to draw 121 virtual light sources on the display panel structure model based on the light-emitting points formed by the 11*11 light source array to form an 11*11 virtual light source array. Further, when drawing the virtual light source, a sphere with a radius of 1 mm may also be drawn with the light-emitting point as the center of the sphere as the virtual light source.

[0073] S203: Use a visualization analysis tool to configure the parameters of the three-dimensional virtual model, so that the test light rays emitted by the image source module are reflected by the mirror assembly and the imaging assembly, and a test virtual image is formed on the imaging plane.

[0074] In the embodiments of the present disclosure, after the terminal device obtains the three-dimensional virtual model of the head-up display system, through step S203, use a visualization analysis tool to load the three-dimensional virtual model. In the visualization analysis tool, configure the parameters of the three-dimensional virtual model, so that the test light rays emitted by the image source module are reflected by the mirror assembly and the imaging assembly, and a test virtual image is formed on the imaging plane. Among them, the visualization analysis tool can be KeyShot software. KeyShot is an interactive ray tracing and global illumination rendering program that can produce photo-realistic 3D rendered images without complex settings.

[0075] In some possible embodiments, it is described by taking the imaging assembly including a windshield and the mirror assembly including a curved mirror as an example. Correspondingly, the optical structure model includes a windshield structure model corresponding to the windshield and a curved mirror structure model corresponding to the curved mirror;

[0076] Then, the above-mentioned parameter configuration of the three-dimensional virtual model may include the following steps: set the material parameters of the windshield structure model and the curved mirror structure model; set the color parameters of the virtual light source and the imaging plane. Specifically, the material of the curved mirror in the curved mirror structure model can be set to aluminum polished material, and the material of the windshield in the windshield structure model can be set to glass material with a white base; the virtual light source and the imaging plane are set with two easily distinguishable colors. For example, the virtual light source is set to red, and the background color of the imaging plane is set to black.

[0077] S205: Set an observation window for the test virtual image according to the eye box area of the head-up display system to obtain at least one observation image of the test virtual image.

[0078] In the embodiments of the present disclosure, the eye box area represents the eye range where the test virtual image can be seen; in the visualization analysis tool, after completing a series of parameter settings for the three-dimensional virtual model, the virtual light source is reflected by the curved mirror structure model and the windshield structure model, and a test virtual image is formed on the imaging plane; then, in the visualization analysis tool, according to the eye box area of the head-up display system, set the observation window of the test virtual image, and the situation of the actual human eye looking at the virtual image from the eye box area can be presented in the observation window. By collecting the images in the observation window, at least one observation image is obtained, and then the imaging effect of the head-up display device is analyzed according to the at least one observation image.

[0079] In some possible embodiments, the eye box area includes at least one preset eye position; as Figure 6 shownFigure 6 It is a schematic diagram of an eyebox area provided by an embodiment of the present disclosure. Generally, the eyebox area is a rectangle, and there are 9 preset eye positions in the eyebox area in this schematic diagram. The 9 preset eye positions are distributed at the edge positions and the center position of the rectangle.

[0080] The following introduces two specific embodiments of the above step S205.

[0081] In the first specific embodiment, at least one observation image corresponds to at least one preset eye position; correspondingly, the above S205 may include: for each preset eye position among at least one preset eye position, fixing the observation window of the test virtual image at the position corresponding to each preset eye position, and collecting the image in the observation window to obtain the observation image corresponding to each preset eye position.

[0082] Specifically, it will be described in detail in combination with Figure 6 the eyebox area shown. Under an 11×11 virtual light source array, as Figure 7 shown, in the KeyShot software, the observation window is respectively set at 9 preset eye positions ( Figure 7 taking the observation window placed at the central preset eye position as an example), and the image in the observation window at each preset eye position is collected to obtain the observation image corresponding to each preset eye position; that is, the human eye observation point is pulled to each preset eye position in the eyebox area, making the human eye as close as possible to each preset eye position to simulate the situation of the human eye looking at the virtual image from the preset eye position. For example, when the observation window is set at the central preset eye position, the image presented in the observation window may be as Figure 8 shown, that is, the virtual image presented by 121 virtual light sources; similarly, when the observation window is set at other preset eye positions, the virtual images seen at other eye positions can also be observed.

[0083] In the second specific embodiment, at least one observation image includes multiple consecutive observation images; correspondingly, the above S205 may include: moving the observation window of the test virtual image from one side of the eyebox area to the other side in a dynamic translation manner within a preset translation time, and collecting the images in the observation window within the preset translation time to obtain multiple consecutive observation images.

[0084] Specifically, it will be described in detail in combination with Figure 6 the eyebox area shown. Under an 11×11 virtual light source array, as Figure 9As shown, in the KeyShot software, place the observation window at the far left of the eye box area first, and set the preset translation time and translation distance to ensure that the observation window can move from one side of the eye box area to the other side within the preset translation time; that is, pull the human eye observation point to the leftmost eye position in the eye box area, and simulate the situation where the human eye moves from the leftmost eye position in the eye box area to the rightmost eye position to view the virtual image. Continuously collect the images in the observation window within the preset translation time, and obtain the continuous multiple observation images as shown in Figure 10 which is equivalent to the situation of the virtual image observed when the human eye moves from the leftmost position to the rightmost position in the eye box. When collecting the images in the observation window, an appropriate resolution can be set, and finally, the continuous multiple observation images can be output in the form of a video. Among them, the preset translation time can be 20s, and the translation distance can be 130mm. This translation distance is determined according to the lateral movement distance of the driver's eyes in the real three-dimensional space in the actual application scenario.

[0085] In the above two embodiments, by setting the three-dimensional virtual model in the visualization analysis tool, generating the test virtual image and the observation images of the test virtual image to simulate the actual imaging effect. In this way, the imaging effect of the HUD is presented in a visual way, which is beneficial to quickly and effectively judge the quality of the HUD imaging effect. In the first specific embodiment above, the test virtual images at each preset eye position in the eye box area are presented in the form of static pictures, which is convenient for intuitively confirming the imaging effect of the HUD at each eye position. In the second specific embodiment above, the test virtual images in the dynamic process from one side to the other side of the eye box area are presented in the form of a video, and the position change and shape change of the virtual images corresponding to each virtual light source can be intuitively seen, that is, to a certain extent, it reflects the size of the dynamic distortion.

[0086] In a further possible embodiment, at least one of the preset eye positions includes a central preset eye position, as shown in Figure 6 the central preset eye position shown is the preset eye position in the central position among the 9 preset eye positions; for the first embodiment above, the visualization analysis method of the embodiments of the present disclosure may further include the following steps as shown in Figure 11 :

[0087] S1101: Overlap at least one observation image based on the central preset eye position to obtain an overlapping image.

[0088] In step S1101, the terminal device can use the central preset eye position as a reference center to overlap at least one observation image to obtain an overlapping image; subsequently, the imaging effect of the HUD can be judged based on the overlapping image.

[0089] S1103: Determine the ghosting state of the test virtual image based on the overlapping image.

[0090] S1105: Determine the imaging effect of the head-up display device according to the ghosting state.

[0091] Generally, if the imaging effect of the HUD is good, the position and size of the test virtual image observed at each preset eye position in the eye box area should not change significantly, that is, there is no ghosting in the test virtual image in the overlapping image; based on this, in steps S1103 - S1105, the terminal device can determine the ghosting state of the test virtual image based on the overlapping image, and the ghosting state of the test virtual image includes the presence of ghosting and the absence of ghosting; then, the terminal device can determine the imaging effect of the head-up display device according to the ghosting state. If there is ghosting in the test virtual image in the overlapping image, it is determined that the imaging effect of the HUD is poor; if there is no ghosting in the test virtual image in the overlapping image, it is determined that the imaging effect of the HUD is good; the specific determination criteria can be adjusted according to actual applications.

[0092] In practical applications, it is possible to determine whether there is ghosting in the test virtual image in the overlapping image manually. Specifically, generally, ghosting is likely to occur at the edge part, and attention can be focused on whether there is ghosting in the edge part of the image; or, it is possible to determine whether there is ghosting in the test virtual image in the overlapping image automatically; in some possible embodiments, the terminal device can randomly select one observation image from at least one observation image as the standard image; then automatically compare the overlapping image with the standard image; specifically, compare the pixel data corresponding to each pixel position (or edge pixel position) of the overlapping image with the pixel data at the corresponding pixel position in the standard image to obtain the pixel data comparison result; if there is a situation where the pixel data at the same pixel position in the pixel data comparison result is inconsistent, it is determined that there is ghosting in the test virtual image.

[0093] Specifically, overlapping the 9 observation images corresponding to the above 9 preset eye positions can obtain an overlapping image as shown in Figure 12 Since each observation image is formed by the test virtual image reflected by 121 virtual light sources, after overlapping the observation images, observe the ghosting state of the test virtual image. If there is no ghosting in the test virtual image, it indicates that the positions and sizes of the virtual images seen at 9 eye positions are unified, that is, the imaging effect of the HUD is good; conversely, if there is ghosting as shown in Figure 12 it indicates that the positions of the virtual images observed at different eye positions are offset, and the imaging effect of the HUD is poor.

[0094] In a further possible embodiment, for the above second embodiment, subsequently, multiple consecutive observation images can also be output in the form of a video, and the position changes and shape changes of the virtual images corresponding to each virtual light source can be observed manually; if neither the position nor the shape of the virtual image corresponding to the virtual light source changes, it indicates that the imaging effect of the HUD is good; if the position or shape of the virtual image corresponding to the virtual light source changes, it indicates that the imaging effect of the HUD is poor; as shown inFigure 10 As shown, by observing the virtual image of the virtual light source in the upper left corner, it can be seen that the virtual image on the left is in a state of shifting to the left, indicating that the imaging effect of the HUD is poor.

[0095] In summary, a visualization analysis method for a head-up display device provided by an embodiment of the present disclosure configures parameters of a three-dimensional virtual model of a head-up display system through a visualization analysis tool to obtain a test virtual image; then, in the visualization analysis tool, an observation window of the test virtual image is set according to the eye box area of the head-up display system, and at least one observation image of the test virtual image is obtained. The at least one observation image can intuitively present the imaging effect of the head-up display device. In this way, it is beneficial to quickly and conveniently analyze the imaging effect of the HUD, which plays an important role in improving and enhancing the imaging effect of the HUD.
