[0002] The display control technology of a head-up display system refers to the ability to directly view three-dimensional images with the naked eye without the user wearing special 3D glasses. The display control of a head-up display system mainly includes lenticular grating display technology and slit grating display technology. Currently, the widely used one is the lenticular grating display technology, which realizes light splitting by attaching a special lenticular lens on a conventional display screen, enabling the user's left and right eyes to see different images and fuse them into a 3D image in the brain.

[0060] To make the objectives, technical solutions, and advantages of this application more clear, the following embodiments of this application will be further described in detail with reference to the accompanying drawings. Obviously, the described embodiment is only one embodiment of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0061] The “embodiment” referred to herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present application. In the description of the embodiments of the present application, it should be understood that the terms “first”, “second”, etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as “first”, “second”, etc. may explicitly or implicitly include one or more of the features. Moreover, the terms “first”, “second”, etc. are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms “including”, “having” and “for” and any variations thereof are intended to cover non-exclusive inclusions.

[0062] See also Figure 1 , Figure 1It is a schematic diagram of an application environment provided by an embodiment of the present application. The application environment may include a Head Up Display (HUD). The HUD may include a head-up display device and a window, i.e., a windshield. The head-up display device may include an image source, a curved mirror, and a flat mirror. The image source may include a backlight, a display screen, and a lenticular grating. The lenticular grating may be attached to the display screen.

[0063] By detecting the positions of the user's left and right eyes, the fixation positions of the left and right eyes in the eye box are respectively determined. The first target view area set corresponding to the left eye position and / or the second target view area set corresponding to the right eye position are determined from the view area partition set. The first pixel area corresponding to the first target view area set and / or the second pixel area corresponding to the second target view area set are determined from the display screen. The first pixel area and the second pixel area are controlled to be in a light-emitting state, so that the imaging light of the first image emitted by the image source is reflected by the window and then incident on the first target view area set, and the imaging light of the second image emitted by the image source is reflected by the window and then incident on the second target view area set. The first image and the second image are two images with parallax. The two images having parallax means that when the same object is observed by the left and right eyes at a certain designed virtual image distance, the position of the object in the images seen by the left and right eyes is different. The farther the virtual image distance is, the smaller the difference is, and the larger the virtual image distance is, the larger the difference is. It should be understood that at least some of the image elements in these two images are the same.

[0064] A head-up display device is an integrated electronic display device including electronic components, display components, controllers, etc. It projects information such as vehicle speed, navigation information, and warning information into the driver's field of vision in the form of images and characters, and is widely used in vehicles for driving assistance. Figure 2 It is a schematic diagram of the imaging of a naked-eye 3D image provided by an embodiment of the present application. The principle of the naked-eye 3D image is that through the optical design of the head-up display system, the user's left eye sees image P1 through an imaging structure (such as a windshield), and the right eye sees image P2. Since image P1 and image P2 form binocular parallax, the user sees the object with a sense of depth and space, and a three-dimensional picture with a sense of depth is synthesized in the user's brain. Its characteristic is that by changing the position between these two images viewed by the user, the binocular parallax is adjusted, so that the virtual image distance felt subjectively by the user changes. In fact, the virtual image distance remains unchanged. The closer the two images are, the closer the virtual image distance felt subjectively by the user is. On the contrary, the farther the two images are, the farther the virtual image distance felt subjectively by the user is.

[0065] Figure 3 It is a schematic diagram of image crosstalk existing in the existing head-up display system. Refer to Figure 3, the eye box is divided into four visual area zones e1, e2, e3, and e4. The distance between the user's two eyes is the width of the two visual area zones, such as the distance in direction a. When it is detected that the user's left eye position is located in the visual area zone e1, the right eye position is located in the visual area zone e3. It is preset that the left eye sees the first image P1 and the right eye sees the image P2. However, when the user changes the head posture, such as turning the head to the left, the user's left eye position exceeds the eye box. Since the eye box is not strictly divided, images may be seen in the area beyond the eye box. Moreover, according to the optical design of the HUD, it is believed that the divided eye box is periodically repeated. Therefore, the image actually seen by the left eye may be the image P2 for the right eye. When the right eye moves from the visual area zone e3 to the visual area zone e2, the actual image seen by the right eye may be the image P1 for the left eye. As a result, crosstalk occurs between the images seen by the left and right eyes of the user, seriously affecting the user experience.

[0066] Based on this, the present application provides a display control method, device, equipment and medium for a head-up display system.

[0067] Before implementing the display control method for a head-up display system, the eyebox can be partitioned according to the parameters of the lenticular grating to obtain a set of viewing zone partitions. Furthermore, the pixel area covered by each lenticular lens in the lenticular grating can be determined from the display screen. Based on the splitting relationship between the lenticular lens and the viewing zone partitions, the pixel area corresponding to each viewing zone partition can be determined.

[0068] Figure 4 This is a schematic diagram of a set of viewing area partitions provided in an embodiment of the present application. An image source is incident on each viewing area partition through a window, i.e., a windshield. During the design of a 3D HUD, a lenticular lens system can be designed so that one lenticule covers several pixel areas on the display screen, equivalent to treating several pixel areas on the display screen as a complete pixel. When partitioning the eyebox, the eyebox can be partitioned based on the number of pixel areas covered by each lenticule in the lenticular lens system to obtain a set of viewing area partitions. The viewing area partitions are periodically repeated. For example, if one lenticule covers four pixel areas on the display screen, the eyebox can be divided into four viewing area partitions. If one lenticule covers five pixel areas on the display screen, the eyebox can be divided into five viewing area partitions. If one lenticule covers five pixel areas on the display screen, the eyebox can be divided into six viewing area partitions. Optionally, the number of viewing area partitions can be greater than three and not an integer multiple of three. Furthermore, to avoid excessive resolution compression of the virtual image, the eyebox is typically divided into four or five viewing area partitions.

[0069] As an illustrative example of the present invention, the eyebox can also be partitioned to obtain a set of viewing area partitions based on the surface shape of the lenticular grating, the grating thickness, the refractive index of the grating material, the refractive index of the glue bonding the grating and the glue thickness, and the optical parameters of the display screen, such as the thickness and refractive index of the various layers involved between the filter and the top surface of the LCD. For example, if a lenticular lens covers 4 pixel areas in the display screen, the eyebox can be divided into 2 (2 + 4 * n) areas, where n = 0, 1, 2, 3... If a lenticular lens covers 5 pixel areas in the display screen, the eyebox can be divided into 2 (2.5 + 5 * n) areas, where n = 0, 1, 2, 3...

[0070] The following describes a specific embodiment of a display control method for a head-up display system of the present application. Figure 5 This is a flow chart of a display control method for a head-up display system provided by an embodiment of the present application. This specification provides the method operation steps shown in the embodiment or flow chart, but more or fewer operation steps may be included based on routine or non-creative work. The order of steps listed in the embodiment is only one of many execution orders and does not represent the only execution order. In actual execution, the method can be executed in the order shown in the embodiment or the figure or in parallel (for example, in a parallel processor or multi-threaded processing environment).

[0071] Specific as Figure 5 As shown, the display control method of the head-up display system may include:

[0072] S501: Detect the positions of the left and right eyes of the user, and determine the gaze positions of the left and right eyes in the eye boxes respectively.

[0073] In an embodiment of the present application, the eyebox may include a set of viewing area zones, each of which may have a corresponding pixel area on the display screen. The lenticular lenses in the lenticular lens grating overlying the display screen may split imaging light emitted by an image source into corresponding viewing area zones, so that each viewing area zone has a corresponding pixel area. The gaze position may refer to the relative position of the user's eyes in the eyebox.

[0074] By detecting the left and right eye positions of the user in real time, the luminous state and displayed image of the pixel area in the display screen can be adjusted in real time, thereby improving the real-time performance of the subsequent head-up display control.

[0075] S503: Based on the gaze positions of the left and right eyes in the eye boxes respectively, determine a first target visual area partition set corresponding to the left eye position and / or a second target visual area partition set corresponding to the right eye position from the visual area partition sets.

[0076] In the embodiments of the present application, the view division set may refer to the entire area into which the eye box is divided, which may include all view divisions. Determining the view divisions in the view division set as the target view division set may mean determining one view division in the view division set as the target view division set, or determining multiple view divisions in the view division set as the target view division set.

[0077] In an illustrative example of the present invention, when the fixation position of the left eye in the eye box is within a preset distance from the geometric center of the view division in the view division set, and the fixation position of the right eye in the eye box is within a preset distance from the geometric center of the view division in the view division set, the view division where the fixation position of the left eye in the eye box is located may be determined as the first target view division set corresponding to the left eye position, and the view division where the fixation position of the right eye in the eye box is located may be determined as the second target view division set corresponding to the right eye position.

[0078] In an illustrative example of the present invention, when the fixation position of the left eye in the eye box is within a preset distance from the boundary between two adjacent view divisions in the view division set, and the fixation position of the right eye in the eye box is within a preset distance from the boundary between two adjacent view divisions in the view division set, the two adjacent view divisions at the boundary where the fixation position of the left eye in the eye box is located may be determined as the first target view division set corresponding to the left eye position, and the two adjacent view divisions at the boundary where the fixation position of the right eye in the eye box is located may be determined as the second target view division set corresponding to the right eye position.

[0079] In an illustrative example of the present invention, when the fixation position of the left eye in the eye box is within a preset distance from the geometric center of the view division in the view division set, and the fixation position of the right eye in the eye box is within a preset distance from the boundary between two adjacent view divisions in the view division set, the view division where the fixation position of the left eye in the eye box is located may be determined as the first target view division set corresponding to the left eye position, and the two adjacent view divisions at the boundary where the fixation position of the right eye in the eye box is located may be determined as the second target view division set corresponding to the right eye position.

[0080] In an illustrative example of the present invention, when the fixation position of the left eye in the eye box is within a preset distance from the boundary between two adjacent view divisions in the view division set, and the fixation position of the right eye in the eye box is within a preset distance from the geometric center of the view division in the view division set, the two adjacent view divisions at the boundary where the fixation position of the left eye in the eye box is located may be determined as the first target view division set corresponding to the left eye position, and the view division where the fixation position of the right eye in the eye box is located may be determined as the second target view division set corresponding to the right eye position.

[0081] An illustrative example of the present invention, when the gaze position of the left eye position in the eye box is located within a preset distance from the boundary of the boundary visual area zone in the visual area zone set, and the gaze position of the right eye position in the eye box is located within a preset distance from the boundary of the two adjacent visual area zones in the visual area zone set, the boundary visual area zone where the gaze position of the left eye position in the eye box is located and the relative boundary visual area zone in the visual area zone set can be determined as the first target visual area zone set corresponding to the left eye position, and the two adjacent visual area zones at the boundary where the gaze position of the right eye position in the eye box is located can be determined as the second target visual area zone set corresponding to the right eye position; wherein, the distribution direction of the boundary visual area zones in the visual area zone set is opposite to the distribution direction of the relative boundary visual area zones in the visual area zone set.

[0082] An illustrative example of the present invention, when the gaze position of the left eye position in the eye box is located within a preset distance from the boundary of two adjacent visual area partitions in the visual area partition set, and the gaze position of the right eye position in the eye box is located within a preset distance from the boundary of a boundary visual area partition in the visual area partition set, the two adjacent visual area partitions at the boundary where the gaze position of the left eye position in the eye box is located can be determined as the first target visual area partition set corresponding to the left eye position, and the boundary visual area partition where the gaze position of the right eye position in the eye box is located and the relative boundary visual area partition in the visual area partition set can be determined as the second target visual area partition set corresponding to the right eye position; wherein, the distribution direction of the boundary visual area partition in the visual area partition set is opposite to the distribution direction of the relative boundary visual area partition in the visual area partition set.

[0083] By determining the target visual area partition sets corresponding to the left and right eye positions from the visual area partition sets based on the gaze positions of the left and right eye positions in the eye boxes respectively, the target visual area partition sets can be accurately determined according to the internal area or boundary of the visual area partition based on the gaze position, thereby improving the accuracy of the display control of the subsequent head-up display system.

[0084] S505: Determine, from the display screen, a first pixel region corresponding to the first target viewing area partition set and / or a second pixel region corresponding to the second target viewing area partition set.

[0085] In an embodiment of the present application, after determining the first target view area partition set and the second target view area partition set, the first pixel area corresponding to the first target view area partition set and the second pixel area corresponding to the second target view area partition set can be determined from the display screen based on the correspondence between each view area partition and the pixel area.

[0086] By determining the pixel area corresponding to each visual area partition in the target visual area partition set based on the correspondence between each visual area partition and the pixel area, the accuracy of the subsequent display control of the head-up display system can be improved.
