[0052] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0053] 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 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 disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0054] Before disclosing the embodiments of the present invention, the following technical terms are explained:

[0055] Field of view (FOV), see Figure 1 The angle formed by the two edges of the maximum range of the image 10 of the target object that can pass through the lens 11, with the lens of the optical instrument as the vertex, is called the field of view angle, including the horizontal field of view angle 12 and the longitudinal field of view angle 13.

[0056] Horizontal field of view (HFOV) 12: For a rectangular virtual image, the angle between the midpoints of the left and right vertical sides and the eye point is the horizontal field of view.

[0057] Vertical field of view (VFOV): For a rectangular virtual image, the angle between the midpoints of the upper and lower horizontal sides and the line connecting the eye point is the vertical field of view.

[0058] Virtual image distance (VID) 20, see Figure 2 , refers to the distance from the user's eye position 21 to the projected virtual image 22, in the figure 23 is a horizontal plane, 24 is an imaging component, such as a windshield.

[0059] HUD projection range, see Figure 3 , refers to the coverage area of ​​the HUD that can be seen by the user's eye position 21 and the virtual image distance 20 of the virtual image 23 from the human eye, which can be specifically calculated through the horizontal field of view angle 12, the vertical field of view angle 13 and the downward viewing angle.

[0060] Three Dimensional (3D) display, see Figure 4 Through optical design, the user sees the parallax image P1 on the imaging component through the left eye viewpoint 41, and the parallax image P2 on the imaging component through the parallax image 42. The binocular parallax between the parallax images P1 and P2 makes the objects seen by the user have a sense of depth and space. The images seen by the left eye viewpoint 41 and the right eye viewpoint 42 are synthesized into a three-dimensional picture with a sense of depth in the user's brain. By changing the positional relationship between the two images to adjust the binocular parallax, the virtual image distance subjectively felt by the user changes (in fact, the virtual image distance remains unchanged). The closer the two images are, the closer the virtual image distance subjectively felt by the user; conversely, the farther the two images are, the farther the virtual image distance subjectively felt by the user.

[0061] Head Up Display (HUD) is a driving assistance instrument used in automobiles. It is a comprehensive electronic display device composed of electronic components, display components, controllers, etc. It can project information such as vehicle speed, navigation information, and warnings in the form of images and characters in front of the driver through optical components.

[0062] Panorama-Head-up-Display (PHUD), see Figure 5The image is output by the image display component 51 on the dashboard of the car and projected to the lower area of ​​the windshield 52 for display. The end user observes the corresponding image 54 at the corresponding position 53. This lower area can basically cover the entire lateral area of ​​the windshield. Compared with HUD, PHUD usually has no 3D effect.

[0063] Based on this, an embodiment of the present disclosure provides a method for displaying an image, using an image generation component.

[0064] The image generating component is used to project image light, and the image light carries image information. After the image light propagates through the optical path, it is projected onto the imaging component for imaging, and the image on the imaging component is generally a virtual image. When the user observes the imaging component, he can observe the image on the imaging component. In this embodiment, there is no special limitation on the image generating component, and it can be selected according to actual conditions.

[0065] See also Figure 6 , the display methods include:

[0066] S61. Determine at least one preset viewpoint position.

[0067] The viewpoint position is the position where the user's line of sight intersects with the center of the image when the user is observing.

[0068] However, during the imaging process, the position of the user's line of sight is not fixed. When the user moves, the position of his or her line of sight also changes. If the center of the image remains unchanged, the image will be distorted to a certain extent in the user's eyes, which will affect the user's viewing experience.

[0069] At this time, in order to avoid distortion of the image in the user's eyes due to changes in the position of the user's line of sight, at least one preset viewpoint position can be set. In some preferred embodiments, multiple preset viewpoint positions can also be set, and the number of preset viewpoint positions is more important than the number of preset viewpoint positions, and the more stable the three-dimensional effect of the imaging.

[0070] The preset viewpoint position is the position where the user's line of sight intersects with the center of the image before and after the user moves. The preset viewpoint position can be determined based on the movement trajectory of the user's line of sight, can be obtained in real time during the movement of the user's line of sight, or can be set in advance.

[0071] It should be noted that when the image on the image generation component changes, the change type includes but is not limited to position, shape, size, color, etc., the corresponding image on the imaging component will also change, and the image on the image generation component and the image on the imaging component are linked. The reason is that the light propagation between the image generation component and the imaging component is point-to-point. Therefore, when the initial viewpoint position on the image generation component changes, the initial viewpoint position on the imaging component will also change, and the image observed by the end user will also change accordingly. In order to facilitate the control of the display of the image, the initial viewpoint position mentioned in this embodiment is generally preferably the initial viewpoint position on the image generation component.

[0072] The preset viewpoint position is described below through three embodiments:

[0073] In the first embodiment, before step S61, the display method further includes:

[0074] Obtain at least one coordinate position of the user's eyes.

[0075] The coordinate position may reflect the user's line of sight direction, and further reflect the position where the line of sight intersects with the center of the image, that is, the preset viewpoint position.

[0076] In this embodiment, there is a one-to-one correspondence between at least one coordinate position and at least one preset viewpoint position, and at least one coordinate position is used to determine at least one preset viewpoint position. Therefore, the preset viewpoint position can be determined by obtaining the coordinate position, and the preset viewpoint position can be determined by the coordinate position in step S61.

[0077] See also Figure 7 , the coordinate position can be obtained from the coordinate sensor 71, and the coordinate sensor 71 can obtain information such as the coordinate position and sight direction of the human eye. In this embodiment, it is preferred to obtain the coordinate positions of the left eye 72 and the right eye 73 respectively. Since the final image 54 in this embodiment is an image with a 3D effect, based on Figure 4 , three-dimensional imaging requires seeing two parallax images P1 and P2 through the left eye viewpoint and the right eye viewpoint respectively, and forming binocular parallax between the parallax images of the left eye and the right eye, so that the objects seen by the user appear to have a three-dimensional sense.

[0078] Therefore, when the user's eyes move, the coordinate positions of the moving left eye 72 and right eye 73 are obtained through the coordinate sensor 71, and the preset viewpoint positions corresponding to the coordinate positions of the left eye and the right eye are determined respectively. Based on the two preset viewpoint positions, the two parallax images P1 and P2 can be adjusted in real time according to the movement of the user's eyes, and the visual parallax formed between the two parallax images enables the user to always view the ideal imaging with 3D effect.

[0079] In the second embodiment, before step S61, the display method further includes:

[0080] Get at least one initial viewpoint position.

[0081] Among the at least one initial viewpoint position, the initial viewpoint position that satisfies the first preset condition is used to determine as at least one preset viewpoint position. The preset viewpoint position is obtained by screening according to the initial viewpoint position. By setting the first preset condition, the screened initial viewpoint position can match the position change of the user's line of sight, so that when the user observes the image, the occurrence of image distortion can be reduced.

[0082] The first preset condition includes initial viewpoint positions that are continuously arranged within a preset distribution range. The preset distribution range represents the distribution range of the preset viewpoint positions, which can be determined according to an algorithm.

[0083] For example, by counting and classifying the historical sight positions of the user, the distribution pattern and distribution range of the user's sight positions can be determined, and then the preset distribution range can be determined based on the distribution range of the user's sight positions.

[0084] In the third embodiment, the number and arrangement of preset viewpoint positions are associated with the number and arrangement of pixel positions, specifically:

[0085] See also Figure 8 The image generation component generally includes a display panel 81 and a grating 82, and the grating 82 is arranged opposite to the display panel 81. The display panel 81 is used to display images. Figure 9-10 Pixel positions are distributed on the display panel 81, and a sub-pixel is set at a pixel position. The sub-pixel can be composed of lamp beads. The "R", "G" and "B" shown in the figure represent the lamp beads of three colors, namely red, green and blue, respectively.

[0086] A grating 82 covers at least one pixel position on the display panel 81. Fig. 9 As shown, a grating covers 50 pixel positions on the display panel 81; or as shown Fig.10 As shown, a grating covers 8 pixel positions on the display panel.

[0087] The number of preset viewpoint positions and the number of pixel positions covered by the grating may be the same or different. However, in order to facilitate the control of the imaging process, the number of preset viewpoint positions is generally set based on the number of pixel positions covered by the grating, so that the number of preset viewpoint positions is the same as the number of pixel positions covered by the grating.

[0088] In addition, the arrangement of at least two of the at least one preset viewpoint position is the same as the arrangement of at least two of the at least one pixel position. Since the arrangement of the pixel positions is continuous and uniform, the spatial arrangement of the obtained preset viewpoint positions is also continuous and uniform.

[0089] The parallax image adjusted based on the above preset viewpoint position can be arranged in the same arrangement as the pixel position. When the user's line of sight moves from one position to another, the parallax difference felt by the eye will become smaller, and the changes in the viewed image will be smoother, reducing the visual jump. Also, due to the continuous distribution of the preset viewpoint position in space, the user can obtain a clear stereoscopic visual effect in a larger range, thereby expanding the observation area, and can reduce the stereoscopic image distortion caused by slight movements of the user's head, thereby providing a more stable stereoscopic visual experience.

[0090] S62: Acquire an initial image and imaging parameters of each preset viewpoint position in at least one preset viewpoint position.

[0091] The initial image is set according to the imaging requirements. The initial image is generally an image that has not been processed. The image information contained in the initial image is the same as the image information contained in the parallax image. The imaging parameters include but are not limited to the optical parameters of the image generation component, the virtual image distance, the distance between the left and right eye images on the virtual image, and any one or more of the imaging. The optical parameters include but are not limited to FOV, VID, the resolution of the image generation component, and the actual used area of ​​the image generation component, which can be selected according to the actual situation.

[0092] S63 , adjusting the parallax of the initial image according to the imaging parameters of each preset viewpoint position, to obtain a parallax image matching each preset viewpoint position.

[0093] The parallax range of each preset viewpoint position can be calculated according to the imaging parameters of each preset viewpoint position, and the parallax image of each preset viewpoint position can be obtained by adjusting the parallax of the initial image of each preset viewpoint position according to the parallax range.

[0094] The adjustment process of the parallax of the initial image is explained: for example, if the pupil distance of the human eye is 65mm, if the distance between the left and right eye images on the virtual image is also 65mm, and the VID is 1m away, then the distance of the 3D effect of the imaging felt by the user through the imaging component is 1m away; at this time, if the distance of the 3D effect of the imaging felt by the user through the imaging component is 2m away, without changing the real distance between the imaging component and the user, it can be adjusted by changing the distance between the left and right eye images on the virtual image. When the distance between the left and right eye images on the virtual image and the left and right eye images on the virtual image are reduced, the distance of the 3D effect of the imaging felt by the user through the imaging component becomes farther. According to the principle of similar triangles, it is calculated that the distance between the left and right eye images on the virtual image should be 32.5mm, which is the parallax range mentioned in this embodiment. The parallax image of each preset viewpoint position can be obtained by adjusting the parallax of the initial image at each preset viewpoint position according to the parallax range.

[0095] Wherein, a parallax image corresponding to each preset viewpoint position is obtained based on each preset viewpoint position, so that the user's eyes can observe 3D imaging in an ideal state on the imaging component at each viewpoint position before and after the movement.

[0096] S64: Display the parallax image matching each preset viewpoint position on the image generation component.

[0097] For the parallax images of each preset viewpoint position obtained in the preceding steps, there may be multiple preset viewpoint positions. In this embodiment, all the parallax images matching the viewpoint positions are displayed on the image generation component to project them to the corresponding positions on the imaging component. When the imaging component generates multiple parallax images matching the preset viewpoint positions, when the user moves from one preset viewpoint position to another, the user can always observe the 3D effect of the image because there are matching parallax images.

[0098] In addition, it should be noted that the more preset viewpoint positions there are, the more parallax images there are on the imaging component, and the smaller the intervals between the parallax images. When the user moves from one position to another, the 3D effect of the image viewed by the user will change more smoothly, reducing the sense of visual jump. Similarly, due to the continuous distribution of viewpoints in space, the user can obtain clear stereoscopic visual effects in a larger range, thereby expanding the observation area, and can reduce the stereoscopic image distortion caused by slight movements of the user's head, thereby providing a more stable stereoscopic visual experience.

[0099] In one embodiment, see Fig.11 , step S64 specifically includes:

[0100] S641: Determine a target pixel range that matches each preset viewpoint position.

[0101] The target pixel range is composed of at least one target pixel position on the image generation component, and each target pixel position in the at least one target pixel position is a pixel position that satisfies a second preset condition.

[0102] Specifically, the second preset condition includes the pixel position falling within the imaging range of each preset viewpoint position, and the imaging range is calculated according to each preset viewpoint position and the corresponding imaging parameters. Specifically, the parallax of each preset viewpoint position can be calculated first (the parallax calculation process can refer to the above embodiment), and then the imaging range of each preset viewpoint position is calculated according to the size of the initial image and the parallax of each preset viewpoint position. In some scenarios, it can be understood that the imaging range of each preset viewpoint position is the same as the size of the target pixel range of each preset viewpoint position, but it is not limited to this.

[0103] S642: Display the parallax image that matches each preset viewpoint position within the target pixel range that matches each preset viewpoint position.

[0104] The target pixel range of each preset viewpoint position matches the disparity image of each viewpoint position. For details, see Figure 4 , the preset viewpoint position 41 (that is, the left eye viewpoint position), its target pixel range matches P1, and the preset viewpoint position 42 (that is, the right eye viewpoint position), its target pixel range matches P2.

[0105] For each disparity image at a preset viewpoint position, each target pixel position in the target pixel range can carry the content corresponding to the disparity image at the target pixel position. The content corresponding to the disparity image carried by the target pixel position at the target pixel position can be referred to. Figure 9-10 .

[0106] In this embodiment, at least one preset viewpoint position is first obtained, and a parallax image matching each preset viewpoint position in the at least one preset viewpoint position is generated, and the parallax image of each preset viewpoint position is displayed on the image generation component. Under the projection of the image generation component, the parallax image is projected onto the corresponding imaging component, and the user can perceive a stereoscopic picture with a sense of depth through the parallax image, thereby realizing the 3D effect of imaging. In addition, by setting at least one preset viewpoint position and the parallax image corresponding to the preset viewpoint position, the user is satisfied that there is a corresponding parallax image to match before and after the line of sight moves, so as to ensure the 3D effect of imaging and reduce the jitter of the 3D effect of imaging during the user's movement.

[0107] On the basis of the above embodiments, an exemplary embodiment of the present disclosure provides a panoramic display device, which includes an image generating component. The image generating component displays an image according to the image display method in the above embodiments, and emits image light to an imaging component according to the displayed image.

[0108] See also Figure 8 The image generation component generally includes a display panel 81 and a grating 82, and the grating 82 is arranged opposite to the display panel 81. The display panel 81 is used to display images. Figure 9-10 Pixel positions are distributed on the display panel 81, and a sub-pixel is set at a pixel position. The sub-pixel can be composed of lamp beads. The "R", "G" and "B" shown in the figure represent the lamp beads of three colors, namely red, green and blue, respectively.

[0109] A grating 82 covers at least one pixel position on the display panel 81. Fig. 9 As shown, a grating covers 50 pixel positions on the display panel 81; or as shown Fig.10 As shown, a grating covers 8 pixel positions on the display panel.

[0110] The number of preset viewpoint positions and the number of pixel positions covered by the grating may be the same or different. However, in order to facilitate the control of the imaging process, the number of preset viewpoint positions is generally set based on the number of pixel positions covered by the grating, so that the number of preset viewpoint positions is the same as the number of pixel positions covered by the grating.

[0111] In one embodiment, see Figure 7 The panoramic display device also includes a coordinate sensor 71 and a processor (not shown in the figure).

[0112] The processor is electrically connected to the coordinate sensor 71 and the image generation component 54 respectively. The coordinate sensor 71 is used to collect the coordinate position of the user's eyes, and the processor is used to obtain the coordinate position and generate corresponding control instructions based on the coordinate position and send them to the image generation component 51.
