[0067] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0068] Before introducing the technical solution of the present application in detail, a brief introduction to the background technology of the present application is first given.
[0069] The human eye and brain have three-dimensional visual capabilities, and the objects we see in the real world are three-dimensional, but current displays are all two-dimensional, which limits the acquisition of visual information and visual experience.
[0070] To allow users to experience 3D effects from different angles within a certain range, increase viewing freedom and flexibility, and support simultaneous viewing by multiple users, multi-viewpoint auto-3D display technology is required. Existing auto-3D display devices generally use fixed multi-viewpoint rendering technology. This means that regardless of the number of users, the system generates and projects images in a preset multi-viewpoint mode (e.g., 8 or 12 viewpoints). When a single user is viewing independently, the auto-3D display device still operates in multi-viewpoint rendering mode, which wastes functionality and power consumption, and also results in lower performance for a single user. In other words, auto-3D display devices cannot adapt to various scenarios. A viewpoint refers to the image seen by the eyes. Two viewpoints represent a single person viewing, with the left and right eyes each seeing different views; four viewpoints represent two people viewing, with each person's left and right eyes also seeing different views.
[0071] In response to the above problems, the present application provides a naked-eye 3D display method and display device, which can dynamically adjust the wedge angle of the prism in the display device based on the number of users to transmit the image on the display screen to the eyes of each user. The fewer the number of users, the higher the resolution of the image viewed by the user, which solves the problem of waste of functional power consumption caused by single-user viewing in the related art and avoids the sacrifice of image resolution and brightness. In addition, during the actual viewing process, the user's eye movement process can also be tracked, and the image on the display screen can be dynamically controlled to be transmitted to each user's eyes, thereby improving the display performance of the display device and enhancing the user's viewing experience. The principle is to use the refraction of light by the prism to project the parallax image on the display screen to the visual areas corresponding to the left eye and the right eye respectively, so that the user's left eye and right eye respectively see different parallax images, thereby forming stereoscopic vision.
[0072] The naked eye 3D display method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown, taking a user viewing the display as an example, the user includes a left eye and a right eye. The application environment includes a display device 10, which includes a display screen 101, a stereoscopic conversion component 102 disposed on the display screen surface, and a controller 103. The stereoscopic conversion component 102 includes multiple collimators 1021 and multiple prisms 1022 disposed on the collimator surface. Each prism corresponds to a collimator to form a light adjustment component. The light adjustment component corresponds to a pixel on the display screen. Each collimator is used to collimate the light of the corresponding pixel into parallel light, and the prism corresponding to the collimator is used to change the propagation direction of the parallel light. The controller 103 is used to obtain the number of sensory organs in the display area of the display device 10 and the position of each sensory organ; based on the number of sensory organs, determine the target pixel corresponding to each sensory organ; and according to the position of each sensory organ, adjust the wedge angle of the prism corresponding to the target pixel of each sensory organ; the adjusted prism is used to transmit the image of the target pixel to the corresponding sensory organ.
[0073] Figure 1 The light in the image is emitted by the 2D display screen at a certain angle. This light passes through multiple collimators and is projected into parallel light with a small divergence angle. After entering the prism, the parallel light is perpendicular to the prism's incident surface and continues to propagate straight ahead without deflection. When it encounters the prism's exit surface, the light forms a certain angle with the exit surface. Since the prism's refractive index n is greater than that of air, n0, the light is refracted at the exit surface.
[0074] Figure 2 This is a schematic diagram of the internal principle of the display device. In the figure, θ is the incident angle of the light when it is refracted at the exit surface, which is equal to the prism wedge angle; β is the exit angle of the exiting light.
[0075] According to the refraction principle: n×sinθ=n0×sinβ
[0076] When other conditions remain unchanged, the prism modulates the transmission direction of light, and the light transmission changes by an angle α, which is determined by the prism's refractive index n and the prism wedge angle θ; that is, α=β-θ=arcsin(n-sinθ)-θ
[0077] It can be seen that by adjusting the prism wedge angle θ, the light transmission angle α can be controlled; and when other conditions remain unchanged, the angle α is proportional to θ.
[0078] In an exemplary embodiment, Figure 3 As shown, a naked eye 3D display method is provided, which is applied to Figure 1 The controller in FIG. 1 is taken as an example to illustrate the method, which includes the following steps 101 to 103. Among them:
[0079] S101, obtaining the number of sensory organs in a display area of a display device and the position of each sensory organ.
[0080] The display area of a display device refers to the area where the display screen can be viewed, generally referring to a certain range in front of the display device. Users can only observe the 3D effect more clearly when they are in the display area. The sensory organ refers to the user's left or right eye, representing only one eye. Since each user has both a left eye and a right eye, the number of sensory organs is twice the number of users. Each user's left eye corresponds to the first sensory organ, and the right eye corresponds to the second sensory organ.
[0081] In an embodiment of the present application, a controller may send an image acquisition instruction to an image sensor located in the area where the display device is located, thereby obtaining an image of the display area captured by the image sensor at the current moment. The controller may then perform target tracking on the display area image to determine the number of users in the display area and the location of each user. Based on the number of users, the controller may then determine the number of sensory organs in the display area. Based on the location of each user, the controller may then further locate the two sensory organs of each user to determine the location of each sensory organ.
[0082] Alternatively, the controller may count the number of users entering the display area based on a counter at the entrance of the display area, and determine the number of sensory organs in the display area based on the number of users. The controller may then predict the positions of the two sensory organs of each user based on the pre-set positions of each user.
[0083] Figure 4 It is a schematic diagram of the display area. It can be seen from the figure that at least one viewing user is in the display area of the display device, and an image sensor is installed above the display device to capture images of the display area.
[0084] S102: Determine the target pixel corresponding to each sensory organ according to the number of sensory organs.
[0085] The display screen is used to display a 2D image, which is composed of multiple target pixels.
[0086] In the embodiment of the present application, in order to ensure that both sensory organs of each user can observe the stereoscopic display effect of the display device, it is necessary to divide the 2D image displayed on the display screen according to the number of sensory organs. In the specific division process, assuming that the number of sensory organs is 2, starting from the first sensory organ or the second sensory organ, starting from the first pixel position of the 2D image, the pixels corresponding to the first sensory organ and the second sensory organ are arranged alternately in the 2D image. Figure 5This is a schematic diagram of target pixels corresponding to a user. Taking a row of pixels in a 2D image as an example, L1 represents the pixel corresponding to the first sensory organ (left eye) of the first user, and R1 represents the pixel corresponding to the second sensory organ (right eye) of the first user. As can be seen from the figure, the pixels corresponding to the first sensory organ and the pixels corresponding to the second sensory organ are arranged alternately.
[0087] Assuming that there are multiple sensory organs, then the number of users is at least two, and the pixel points corresponding to the first sensory organs of different users on the display screen and the pixel points corresponding to the second sensory organs on the display screen are arranged alternately. Taking the number of users as an example, Figure 6 This is a schematic diagram of target pixels corresponding to two users. The figure also takes a row of pixels in a 2D image as an example. In the figure, L1 represents the pixel corresponding to the first user's first sensory organ (left eye), R1 represents the pixel corresponding to the first user's second sensory organ (right eye), L2 represents the pixel corresponding to the second user's first sensory organ (left eye), and R2 represents the pixel corresponding to the second user's second sensory organ (right eye). It can be seen from the figure that the pixels are arranged in the order of the pixels corresponding to the first sensory organ of the first user, the pixels corresponding to the second sensory organ of the first user, the pixels corresponding to the first sensory organ of the second user, the pixels corresponding to the second sensory organ of the second user, and the pixels corresponding to the first sensory organ of the first user, which is a cyclic arrangement.
[0088] S103, adjusting the wedge angle of the prism corresponding to the target pixel of each sensory organ according to the position of each sensory organ; the adjusted prism is used to transmit the image of the target pixel to the corresponding sensory organ.
[0089] The wedge angle of the prism refers to the angle between the two refractive surfaces of the wedge-shaped prism, which determines the size and direction of the deflection angle of the prism to the light.
[0090] In an embodiment of the present application, after obtaining the position of each sensory organ, the controller can obtain the position of the target pixel corresponding to the sensory organ for any sensory organ. The deflection angle between the position of the target pixel and the position of the sensory organ is calculated. Based on the mapping relationship between the wedge angle adjustment angle of the prism and the deflection angle, the wedge angle adjustment angle corresponding to the deflection angle is determined. The controller can drive the wedge angle of the prism to move through the driving device until the wedge angle movement angle is the wedge angle adjustment angle. In this way, the prism can transmit the image of the target pixel to the corresponding sensory organ. Through parallel processing in the above manner, the images of all target pixels can be transmitted to each sensory organ, ensuring that every user can observe the three-dimensional effect displayed by the display device.
[0091] In the above-described naked-eye 3D display method, the number of sensory organs and the position of each sensory organ in the display area of the display device are obtained; based on the number of sensory organs, the target pixel corresponding to each sensory organ is determined; and according to the position of each sensory organ, the wedge angle of the prism corresponding to the target pixel of each sensory organ is adjusted; and the adjusted prism is used to transmit the image of the target pixel to the corresponding sensory organ. By obtaining the number of sensory organs and the position of each sensory organ in the display area of the display device, changes in the number of people in the usage scenario can be accurately perceived. Based on the actual number of sensory organs, the display screen is pixel-divided, and the target pixel corresponding to each sensory organ is determined at the pixel level. The wedge angle of the prism is then adjusted based on the position of each sensory organ to transmit the image of the target pixel to the corresponding sensory organ. In other words, whether the number of users is large or small, dynamic pixel allocation can be achieved to ensure that every user can see the 3D effect without idle or wasted resources due to excessive pre-set resources, making this method adaptable to various scenarios.
[0092] The adjustment of the wedge angle of the prism is a key step to ensure that each sensory organ can see the three-dimensional effect. In one embodiment, Figure 7 As shown, the specific contents of adjusting the wedge angle of the prism corresponding to the target pixel of each sensory organ according to the position of each sensory organ include:
[0093] S201 : For any sensory organ, obtain a deflection angle between the position of the sensory organ and the position of a target pixel corresponding to the sensory organ.
[0094] The position of the target pixel refers to the position of the target pixel in space.
[0095] In an embodiment of the present application, for any sensory organ, the controller can obtain the position of the display screen in space and determine the position of the target pixel in the display screen. Based on the position of the display screen in space and the position of the target pixel in the display screen, the position of the target pixel corresponding to the sensory organ is calculated. Afterwards, the controller can convert the position of the sensory organ and the position of the target pixel corresponding to the sensory organ into the same spatial coordinate system, and use the operation rules of spatial vectors to calculate the vector between the position of the sensory organ and the position of the target pixel. Then, according to the vector angle formula, the deflection angle is calculated.
[0096] Alternatively, the controller can also connect the position of the perception organ with the position of the target pixel of the perception organ, and then calculate the angle between the connecting line and the horizontal line of the display screen to obtain the deflection angle between the position of the perception organ and the position of the target pixel corresponding to the perception organ.
[0097] In one embodiment, the specific content of obtaining the deflection angle between the position of the sensory organ and the position of the target pixel corresponding to the sensory organ is introduced, and the specific content includes:
[0098] The angle between the line connecting the position of the sensory organ and the position of the target pixel of the sensory organ and the horizontal line of the display screen is measured, and the measured angle is used as the deflection angle.
[0099] In an embodiment of the present application, a laser transmitter and receiver can be installed around the display screen. A controller can emit a laser beam in the direction of the sensory organ. When the laser beam reaches a reflective marker near the sensory organ (such as a reflective patch worn by the user), it is reflected back to the receiver. The distance is determined by calculating the laser's round-trip time, while an angle encoder is used to measure the angle between the laser beam and the horizontal line of the screen.
[0100] Alternatively, based on the image information collected by the image sensor, a computer vision algorithm can be used to identify the horizontal line of the screen and the position of the sensory organ, and calculate the angle between the line connecting the two and the horizontal line.
[0101] S202: Adjust the wedge angle of the prism corresponding to the target pixel to a deflection angle.
[0102] In an embodiment of the present application, the controller can obtain the current wedge angle of the prism, calculate the deflected wedge angle based on the current wedge angle and the deflection angle, determine the deflection direction of the prism based on the current wedge angle and the deflected wedge angle, and control the prism to deflect in the deflection direction until the wedge angle of the prism is adjusted to the deflection angle.
[0103] In the aforementioned naked-eye 3D display method, for any sensory organ, the deflection angle between the position of the sensory organ and the position of the target pixel corresponding to the sensory organ is obtained; and the wedge angle of the prism corresponding to the target pixel is adjusted to the deflection angle. By calculating the deflection angle between the sensory organ and the target pixel, this method accurately adjusts the wedge angle of the prism corresponding to the target pixel, ensuring that light rays originating from the target pixel, after being refracted by the prism, are accurately transmitted to the corresponding sensory organ along a strictly intended path, thereby achieving precise image focus.
[0104] Furthermore, the prism includes a top transparent glass plate, a bottom transparent glass plate, and a liquid medium disposed in a cavity structure formed by a seal and the two transparent glass plates. The angle of the top transparent glass plate is adjustable. In one embodiment, the specific details of adjusting the wedge angle of the prism corresponding to the target pixel to the deflection angle are described, including:
[0105] Based on the positive or negative deflection angle, the deflection direction of the top transparent glass plate of the prism is adjusted; the adjusted top transparent glass plate is used to change the transmission direction of light.
[0106] Each prism has a film layer on its top surface, sealed with a liquid medium inside. The sides are sealed with seals, and the bottom is sealed with a transparent glass plate. The liquid medium inside must meet certain optical properties, such as a stable and suitable refractive index, high transparency and low absorption, low dispersion, and optical uniformity.
[0107] In one embodiment, the specific content of adjusting the deflection direction of the top transparent glass plate of the prism based on the positive or negative deflection angle includes:
[0108] When the deflection angle is positive, the right side of the top transparent glass plate is controlled to be higher than the left side; the adjusted top transparent glass plate deflects parallel light to the right;
[0109] When the deflection angle is negative, the left side of the top transparent glass plate is controlled to be higher than the right side; the adjusted top transparent glass plate deflects parallel light to the left;
[0110] When the deflection angle is zero, the top transparent glass plate is controlled to be parallel to the display screen; the adjusted top transparent glass plate does not change the parallel light transmission direction.
[0111] In the aforementioned naked-eye 3D display method, the deflection direction of the transparent glass plate at the top of the prism is adjusted based on the positive or negative sign of the deflection angle; the adjusted top transparent glass plate is used to change the direction of light transmission. This method achieves precise control of the light transmission direction by using the positive or negative sign of the deflection angle as the basis for adjusting the deflection direction of the transparent glass plate at the top of the prism.
[0112] Based on the above embodiment, the top and bottom transparent glass plates of the prism each have two electrodes on their surfaces. The first electrode is located on the left side of the top transparent glass plate, the second electrode is located on the left side of the bottom transparent glass plate, the third electrode is located on the right side of the top transparent glass plate, and the fourth electrode is located on the right side of the bottom transparent glass plate. The first and third electrodes are connected to the positive voltage pole, while the second and fourth electrodes are connected to the negative voltage pole. The following describes the specific aspects of controlling the right side of the top transparent glass plate to be higher than the left side and the left side of the top transparent glass plate to be higher than the right side through an embodiment, including:
[0113] Applying voltage to the first electrode plate and the second electrode plate to control the left side of the top transparent glass plate to tilt downward so that the right side of the top transparent glass plate is higher than the left side; and
[0114] Voltage is applied to the third electrode plate and the fourth electrode plate to control the right side of the top transparent glass plate to tilt downward so that the left side of the top transparent glass plate is higher than the left side.
[0115] Figure 8a Schematic diagram of the light adjustment component for left deflection. Figure 8b Schematic diagram of the light adjustment component without deflection, Figure 8c Schematic diagram of a light adjustment component for rightward deflection. In the figure, LU is the first electrode, LD is the second electrode, LU and LD form a pair of electrodes, LU is connected to the positive voltage pole, and LD is connected to the negative voltage pole.
[0116] RU is the third electrode plate, RD is the fourth electrode plate, RU and RD form a pair of electrodes, RU is connected to the positive electrode of the voltage, and RD is connected to the negative electrode of the voltage.
[0117] During operation, the liquid prism is mainly driven by the electrostatic force between the parallel plate capacitors. When voltage is applied to the two ends of the capacitor formed by the parallel plates, the plates will carry charges of opposite polarity and generate electrostatic attraction.
[0118] The capacitance of a parallel plate capacitor can be expressed as: C =
[0119] Among them, the relative dielectric constant of the internal liquid medium is , the dielectric constant in vacuum is , the area of the plates is A, and the distance between the plates is D.
[0120] The potential energy of the product of two parallel plates is:
[0121] Where U is the voltage applied to the plates.
[0122] When a driving voltage is applied between the plates, the electrostatic attraction can be expressed as:
[0123] The formula for calculating electrostatic attraction shows that it is proportional to the width and length of the movable plate, inversely proportional to the square of the distance between the two plates, and directly proportional to the square of the driving voltage. Assuming other conditions remain unchanged, electrostatic attraction can be controlled simply by adjusting the voltage. This alteration of the prism wedge angle is equivalent to indirectly controlling the prism wedge angle through voltage, ultimately controlling the beam transmission angle through voltage.
[0124] When voltage is applied to RU and RD, and voltage U is applied across the capacitor formed by RU and RD, charges of opposite polarity will be present between the plates, generating an electrostatic attraction F. RU will then apply a downward force F to the prism. When the prism reaches its target position, that is, the top transparent glass plate tilts, and the internal liquid medium presents a wedge-shaped prism with a certain angle. Then, voltage U' is applied to LU and LD, generating an electrostatic attraction F' in the same way; this makes the attraction F' = F to achieve force balance, and the prism maintains a certain wedge angle (-θ). At this time, the direction of light transmission changes and deflects to the left, as shown in the figure. Figure 8a shown.
[0125] Continuing with state 8a, the voltage applied to RU and RD is reduced or canceled, that is, F'>F, and the top transparent glass plate changes from tilting to the right to being horizontal. At this time, voltage U is applied to RU and RD again to make F'=F to achieve force balance. The prism becomes a parallel plate, and the light is transmitted in a straight line through the parallel plates without deflection, as shown in the following example. Figure 8b shown.
[0126] Continuing with state 8b, the voltage applied to RU and RD is reduced or canceled, that is, F'>F, and the top transparent glass plate changes from horizontal to tilted to the left. When the target position is reached, voltage U is applied to RU and RD again to make F'=F to achieve force balance, and the prism maintains a certain wedge angle (+θ); at this time, the direction of light transmission changes to deflect left and right, as shown in Figure 8c shown.
[0127] The light is emitted from the display screen, and after being collimated by the collimator to be parallel, it passes through the bottom transparent glass plate of the prism and enters the liquid medium. At the interface between the liquid medium and the top transparent glass plate, the light turns. The angle between the incident direction of the light and the interface is not equal to 90°, so refraction occurs. The refractive index of the top transparent glass plate is n g , the refractive index of the liquid medium is n l , the incident angle θ is equal to the wedge angle of the prism.
[0128] From the law of refraction we can get: n l ×sinθ=n g ×sinβ
[0129] Then, β=arcsin( sinθ)
[0130] The angle between the outgoing light and the original incident light can be expressed as: α=β-θ=arcsin( sinθ)-θ
[0131] By filling the prism with liquid medium, the prism wedge angle can be changed under external driving, thereby changing the light transmission angle. Figure 5As shown, each prism corresponds to a collimator and a pixel, and each prism can be controlled independently. Each prism transmits the light of its corresponding pixel to the user's two sensory organs. The image of pixel L1 is transmitted to the first sensory organ (left eye), and the image of pixel R1 is transmitted to the second sensory organ (right eye). L1 and R1 display images with left and right parallax, respectively, and are controlled separately.
[0132] In the above-mentioned naked-eye 3D display method, voltages are applied to the first and second plates to control the left side of the top transparent glass plate to tilt downward, causing the right side of the top transparent glass plate to be higher than the left side; and voltages are applied to the third and fourth plates to control the right side of the top transparent glass plate to tilt downward, causing the left side of the top transparent glass plate to be higher than the left side. This method applies voltages to the first and second plates, and the third and fourth plates, respectively, to control the tilt of the top transparent glass plate in different directions. The tilt of the glass plate changes the incident and refraction angles of light within the plate, thereby achieving precise adjustment of the light propagation direction and focus position.
[0133] Each user has a first sensory organ (left eye) and a second sensory organ (right eye). The pixels corresponding to the first sensory organs of different users on the display screen are arranged alternately with the pixels corresponding to the second sensory organs on the display screen. Figure 9 As shown, the specific content of determining the target pixel corresponding to each sensory organ according to the number of sensory organs is introduced, and the specific content includes:
[0134] S301, determining the number of users in a display area of a display device based on the number of sensory organs.
[0135] In an embodiment of the present application, after obtaining the number of sensory organs in the display area, the controller can calculate the sum of the numbers of the two sensory organs and use the calculation result as the number of users in the display area of the display device.
[0136] S302 : Based on the number of users, the display image of the display screen is divided into pixels to obtain pixels corresponding to each user.
[0137] In the embodiment of the present application, assuming that there are at least two users, two pixels are sequentially divided into one for each user. After the number of users is arranged, the above division process is repeated until all pixels are divided and the pixels corresponding to each user are obtained. Figure 6 , pixel L1 and pixel R1 are pixels corresponding to the first user, and pixel L2 and pixel R2 are pixels corresponding to the second user.
[0138] S303: Using the left pixel corresponding to each user as the target pixel corresponding to the user's first sensory organ, and using the right pixel corresponding to each user as the target pixel corresponding to the user's second sensory organ.
[0139] In an embodiment of the present application, each user corresponds to two pixels, and the controller can use the left pixel of the two pixels as the target pixel corresponding to the user's first sensory organ, and the right pixel as the target pixel corresponding to the user's second sensory organ.
[0140] It is understandable that the right pixel corresponding to each user can also be used as the target pixel corresponding to the user's first sensory organ, and the right pixel corresponding to each user can also be used as the target pixel corresponding to the user's first sensory organ.
[0141] In the above-mentioned naked-eye 3D display method, the number of users in the display area of the display device is determined based on the number of sensory organs. Based on the number of users, the displayed image on the display screen is divided into pixels to obtain pixels corresponding to each user. The left pixel corresponding to each user is used as the target pixel corresponding to the user's first sensory organ, and the right pixel corresponding to each user is used as the target pixel corresponding to the user's second sensory organ. This method divides the pixels based on the number of users and accurately allocates the pixels corresponding to each user to their left and right eyes. Each user can clearly see the part of their attention without interfering with each other, effectively improving the efficiency and accuracy of information acquisition and significantly optimizing the user's viewing and usage experience.
[0142] In one embodiment, Figure 10 As shown, the specific content of obtaining the number of sensory organs in the display area of the display device and the position of each sensory organ includes:
[0143] S401 , collecting an image in a display area by using an image sensor disposed above the display screen.
[0144] In an embodiment of the present application, when it is necessary to obtain the number of sensory organs in the display area and the location of each sensory organ, the controller can send an image acquisition instruction to an image sensor disposed above the display screen. After receiving the image acquisition instruction, the image sensor can capture an image of the display area and transmit the captured image to the controller.
[0145] S402: Perform target detection on the image in the display area to determine the number of sensory organs and the position of each sensory organ.
[0146] In an embodiment of the present application, after acquiring an image within the display area, the controller may use an object detection algorithm to detect the image within the display area to determine the number and location of sensory organs in the image. For example, the object detection algorithm may be a sliding window method, a deep learning-based object detection algorithm, or the like.
[0147] In the above-mentioned naked-eye 3D display method, an image sensor positioned above the display screen captures images within the display area. Target detection is then performed on the images within the display area to determine the number of sensory organs and the location of each sensory organ. This method uses the image sensor to capture images within the display area in real time. Target detection within the images within the display area accurately determines the number of sensory organs and the location of each sensory organ within the display area.
[0148] The above embodiments are all adjustments before the user watches. During the actual viewing process, the user's movement can be monitored in real time to adjust the wedge angle of the prism in real time. Figure 11 As shown, the method further includes:
[0149] S501 , monitoring the sensory organs of each user during at least one user's viewing process.
[0150] In an embodiment of the present application, while a user is viewing a display device, a controller may control an image sensor disposed above the display device to capture images of the display area in real time, thereby monitoring each user's sensory organs. Alternatively, each user's sensory organs may be monitored using monitoring equipment in the space where the display device is located.
[0151] S502 : If the sensory organ of any user is shifted, the wedge angle of the prism corresponding to the target pixel corresponding to the sensory organ of the user is adjusted based on the position of the shifted sensory organ.
[0152] In an embodiment of the present application, after acquiring the current captured image or the current monitored image, the controller can perform target detection on the currently captured image of the display area to obtain the current position of each sensory organ. The current position is matched with the historical position to determine whether the user's sensory organ has moved.
[0153] After determining that the sensory organ of any user has shifted, the controller can obtain the deflection angle between the position of the sensory organ after the shift and the position of the target pixel corresponding to the sensory organ based on the position of the sensory organ after the shift, and adjust the wedge angle of the prism corresponding to the target pixel to the deflection angle.
[0154] Figure 12a is a schematic diagram of a user at viewing position 1, Figure 12b This is a schematic diagram of a user at viewing position 2. As can be seen from the figure, after the user moves from viewing position 1 to viewing position 2, the wedge angle of the prism corresponding to the target pixel is adjusted, so that the adjusted prism can transmit the image of the target pixel to the user's sensory organs.
[0155] Figure 13a Schematic diagram of the user at viewing positions 1 and 2. Figure 13b This is a schematic diagram of users at viewing positions 1 and 3. One user (the first user) is fixed in position, while the other user (the second user) moves, from viewing position 2 to viewing position 3. The wedge angle of the prism corresponding to the second user's sensory organ needs to be adjusted to direct light transmission so that the wedge angle of the prism moves with the position of the sensory organ.
[0156] If the number of users is greater, the monitoring method is the same as that of one or two users.
[0157] In the aforementioned naked-eye 3D display method, each user's sensory organs are monitored while at least one user is viewing. If any sensory organ of a user shifts, the wedge angle of the prism corresponding to the target pixel corresponding to that user's sensory organ is adjusted based on the shifted sensory organ position. This method monitors the user's sensory organs in real time. When any sensory organ shift is detected, the wedge angle of the prism corresponding to the target pixel is immediately and precisely adjusted based on the new sensory organ position. This ensures that the user maintains a consistent and consistent viewing experience regardless of their movement during viewing.
