Description

Technical Field

[0001] The present application belongs to the field of near eye display (NED) devices, and more specifically, to a binocular display adjustment and FOV consistency compensation method and device for NED devices. Background Art

[0002] Near-eye display devices, such as augmented reality (AR) glasses, virtual reality (VR) head-mounted displays, and other forms of head-mounted display devices, are important achievements in the development of modern science and technology. These devices mainly produce images in front of the user's eyes through optical systems (including lenses and optical projection systems) to achieve the effects of virtual reality or augmented reality. Among them, the field of view (FOV) is defined as the range of virtual images visible to the user, and its size is affected by the size of the display screen used and the design and performance of the optical system. Although the display screen sizes used in these devices are not much different, achieving consistent binocular field of view and image quality is quite challenging due to the differences in binocular optical systems, which may result in differences in the binocular FOV experienced by users. The consistency of binocular field of view is extremely critical to enhancing the immersive experience, reducing visual fatigue, and improving visual quality and depth perception. Therefore, ensuring the consistency of binocular FOV is one of the important considerations in the design of near-eye display devices.

[0003] In existing technologies, an imaging colorimeter is usually used with a test lens with an aperture in front to obtain the distribution of the brightness or MTF of the entire virtual image through imaging, and then based on certain boundary conditions, such as the center brightness or half of the center modulation transfer function (MTF), the boundary of the FOV is determined to complete the FOV test. This method mainly completes the FOV test of the NED device, and does not perform binocular consistency compensation. Summary of the invention

[0004] In view of the defects of the prior art, the purpose of this application is to provide a binocular display adjustment and FOV consistency compensation method and device for NED devices, aiming to solve the problem that the prior art cannot perform binocular FOV consistency compensation for NED devices and cannot ensure the consistency of binocular field of view of NED devices.

[0005] To achieve the above-mentioned purpose, in a first aspect, the present application provides a binocular display adjustment method of a NED device, wherein the NED device comprises: two optical display systems, the two optical display systems are: a left-eye optical display system and a right-eye optical display system, and the method comprises:

[0006] Obtain the FOV and display resolution of the two optical display systems respectively;

[0007] When the two FOVs of the two optical display systems are inconsistent, determining a target FOV; the target FOV is less than or equal to any one of the two FOVs;

[0008] Determine display resolution adjustment values ​​of two optical display systems respectively according to the target FOV, two FOVs and two display resolutions; wherein a ratio of the display resolution adjustment value of each optical display system to the display resolution is equal to a ratio of the target FOV to the FOV of the corresponding optical display system;

[0009] If the display resolution adjustment value of any optical display system is smaller than its display resolution, the size of the picture to be displayed by the optical display system is interpolated according to the display resolution adjustment value, so that the optical display system displays the picture after the size interpolation.

[0010] It is understandable that when the FOVs of the two optical display systems of the NED device are inconsistent, the field of view of the display images of the two optical display systems will be inconsistent; in order to avoid inconsistent binocular display images of the NED device, the binocular display adjustment method provided in the present application can achieve compensation for the binocular display of the NED device without changing the binocular optical system and display hardware parameters of the NED device, thereby ensuring the consistency of the size of the binocular display images of the NED device, making the FOV of the binocular display images consistent, improving the user's visual experience, reducing visual fatigue, and improving visual quality and depth perception.

[0011] In an optional example, the method further includes:

[0012] When the optical display system displays the size-interpolated picture, the pixels outside the pixel area corresponding to the display resolution adjustment value are controlled not to emit light.

[0013] Optionally, after the image to be displayed is interpolated, the image size of the interpolated image will generally be reduced accordingly, and the display resolution of the interpolated image will be the resolution adjustment value; therefore, it is necessary to control the pixels outside the display resolution adjustment value of the optical display system to not emit light, so as to further ensure the consistency of the FOV of the binocular display image.

[0020] It is understandable that when the binocular display adjustment method of the NED device provided in the first aspect is adopted, when the binocular FOV of the NED device is inconsistent, the image to be displayed can be compensated and / or the corresponding sub-pixel can be controlled not to emit light, so that the field of view (i.e., size) of the displayed image after compensation is consistent, thereby achieving consistency compensation for the binocular FOV of the NED device.

[0025] In an optional example, the display adjustment module is further used to control pixels outside a pixel area corresponding to a display resolution adjustment value not to emit light when the optical display system displays the size-interpolated picture.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0044] First, the technical terms involved in the embodiments of the present application are introduced.

[0045] (1) Optical display system

[0046] The optical display system consists of two main parts: the optical system and the display screen, which work together to provide high-quality virtual or real images for display.

[0047] (2) Left-eye optical display system / right-eye optical display system

[0048] In the NED field, the left-eye optical display system and the right-eye optical display system usually refer to independent display systems designed for the left eye and the right eye respectively. This design is common in stereoscopic vision technology; when the NED device is worn by the user, the left-eye optical display system and the right-eye optical display system are located in front of the user's left eye and right eye respectively.

[0049] Among them, a single optical display system can be referred to as a monocular NED device; and the left and right eye optical display systems can be referred to as a binocular NED device.

[0050] (3) Display resolution

[0051] Display resolution refers to the number of pixels that can be displayed on a display device, usually expressed as horizontal pixels × vertical pixels, for example 1920 × 1050.

[0052] Next, the technical solutions provided in the embodiments of the present application are introduced.

[0053] Figure 1is a flow chart of a binocular display adjustment method for a NED device provided in an embodiment of the present application; Figure 1 As shown, the following steps are included:

[0054] Step S101, respectively obtaining the FOV and display resolution of two optical display systems;

[0055] Step S102, when the two FOVs of the two optical display systems are inconsistent, determining a target FOV; the target FOV is less than or equal to any one of the two FOVs;

[0056] Step S103, determining display resolution adjustment values ​​of two optical display systems respectively according to the target FOV, two FOVs and two display resolutions; wherein the ratio of the display resolution adjustment value of each optical display system to the display resolution is equal to the ratio of the target FOV to the FOV of the corresponding optical display system;

[0057] Step S104: if the display resolution adjustment value of any optical display system is smaller than its display resolution, the size of the picture to be displayed by the optical display system is interpolated according to the display resolution adjustment value, so that the optical display system displays the picture after the size interpolation.

[0058] It should be noted that the solution provided in this application is mainly to solve the problem of how to achieve consistency compensation of NED binocular FOV without changing the hardware such as NED optical system and display screen; and how to ensure consistency of displayed content while ensuring consistency of left and right eye FOV. Furthermore, when the binocular FOV difference of NED device is large, one field of view of binocular display is large and the other field of view is small, which cannot guarantee the comfort of users using NED device.

[0059] Optionally, when the optical display system displays the size-interpolated picture, pixels outside the pixel area corresponding to the display resolution adjustment value are controlled not to emit light.

[0060] Obviously, when the binocular FOVs of the NED device are inconsistent, a target FOV that is less than or equal to the two FOVs can be selected, and the FOVs of the display images of the two optical display systems can be made consistent by controlling the display resolutions and / or the sizes of the display images of the two optical display systems; both optical display systems display corresponding images with the target FOV, thereby ensuring that the size (i.e., FOV) of the binocular display images of the NED device is consistent, achieving consistency compensation of the binocular FOV of the NED device, and improving the user experience.

[0061] Wherein, if the display resolution adjustment value of a certain optical display system is less than its display resolution, the size of the picture to be displayed by the optical display system is interpolated according to the display resolution adjustment value, and when the optical display system displays the picture after the size interpolation, the pixels outside the pixel area corresponding to the display resolution adjustment value are controlled not to emit light. For example, assuming that the display resolution adjustment value of a certain optical display system is 1440×900, the display resolution is 1920×1050, and the display resolution of the picture to be displayed by the optical display system is 1920×1050, when performing binocular display adjustment, the picture to be displayed with a display resolution of 1920×1050 must first be interpolated to a picture with a size corresponding to the display resolution of 1440×900, and then the optical display system is controlled to display the interpolated picture, and the pixels outside the 1440×900 area of ​​the optical display system are controlled not to emit light.

[0062] Optionally, if the display resolution adjustment value of the optical display system is equal to its display resolution, the picture to be displayed by the optical display system is not adjusted.

[0063] Among them, when the display resolution adjustment value is equal to its display resolution, the corresponding picture can be directly displayed, and the FOV of the displayed picture is naturally the target FOV.

[0064] For example, the target FOV is the smallest FOV of the two FOVs.

[0065] Among them, when the target FOV is smaller than the FOV of the two optical display systems, it can be understood that the images to be displayed by the binoculars are displayed with a target FOV smaller than their FOV, so as to achieve binocular consistent FOV compensation. In addition, the images to be displayed in the large FOV can also be adjusted to images and displays under the small FOV, so that the two optical display systems are displayed with the smaller FOV of the two FOVs, so as to achieve binocular FOV consistency compensation.

[0066] As a further example, the two FOVs are measured by at least one of a large-field-of-view imaging brightness colorimeter measurement or a spot brightness meter rotation measurement.

[0067] In a specific embodiment, the present application provides a more specific method for adjusting binocular display of a NED device, the method comprising the following steps:

[0068] Step 1: First, test the NED binocular FOV separately. You can use a large field imaging colorimeter to measure, or you can use a spot luminance meter to measure. The FOVs of the left and right eyes are recorded as FOVl of the left eye optical display system and FOVr of the right eye optical display system.

[0069] Step 2. Modify the display screen. The common target FOV that is the same for both eyes is denoted as FOVt, where FOVt needs to be ≤ the minimum value of FOVl and FOVr. The resolutions of the display screens corresponding to the FOVs of the left and right eyes are Resl and Resr respectively. Then, the resolution of the left-eye display screen needs to be adjusted to ReslCorL = FOVt / FOVl Resl. Similarly, the resolution of the right-eye display screen needs to be adjusted to ReslCorR = FOVt / FOVr Resr. Taking the left eye as an example, since FOVt ≤ FOVl, ReslCorL ≤ Resl. If ReslCorL = Resl, then no adjustment is made to the left eye. If ReslCorL < Resl, then the image with a resolution of Resl displayed by the left eye needs to be interpolated to obtain an image with a resolution of ReslCorL, and then the left eye only displays the image corresponding to the center ReslCorL resolution, and the other pixels are set not to emit light. The same applies to the right eye.

[0070] Optionally, when the target FOV selects the minimum value of FOVl and FOVr, the above steps are specifically as follows: The resolutions of the display screens corresponding to the FOVs of the left-eye optical display system and the right-eye optical display system are Resl and Resr respectively. If FOVl > FOVr, then the resolution of the display screen of the left-eye optical display system needs to be adjusted to ReslCor = FOVr / FOVl Resl, and no processing is done to the right eye. If FOVl < FOVr, then the resolution of the display screen of the right-eye optical display system needs to be adjusted to ResrCor = FOVl / FOVr Resr, and no processing is done to the left eye.

[0071] More specifically, in an embodiment, the right-eye optical display system uses an OLED display screen with a resolution of 2560×1440. If it is found that FOVl > FOVr, then the resolution of the display screen of the left-eye optical display system needs to be adjusted to ReslCor = FOVr / FOVl Resl. For example, if FOVl = 90 degrees, FOVr = 85 degrees, and Resl = 2560×1440, then the resolution of the effective area of the display screen of the left-eye optical display system needs to be adjusted to 2417×1360, and the display of other pixels is set to 0. If the effective display area corresponding to the 85-degree FOV of the right-eye optical display system is 2560×1440, then the display screen of the right-eye optical display system needs to be interpolated into an image with a resolution of 2417×1360 for left-eye display.

[0072] Further, when displaying the corrected screen, the optical display system with a smaller FOV normally displays the screen, and the optical display system with a larger FOV displays the corrected display screen.

[0073] Step 3: Finally, display the corrected image to achieve consistent binocular FOV and consistent display content.

[0074] The above three steps constitute the core technical means of this technical solution. Through these technical means, the consistency compensation of NED binocular FOV can be achieved without changing the hardware such as NED optical system and display screen, while ensuring the consistency of display content.

[0075] Figure 2 : is a flow chart of the FOV consistency compensation method of the NED device provided in the embodiment of the present application; Figure 2 As shown, the following steps are included:

[0076] Step S201, determining the FOVs of two optical display systems respectively;

[0077] Step S202: When the FOVs of the two optical display systems are inconsistent, Figure 1 The provided method controls two optical display systems of a NED device to perform display so that the FOVs of the images displayed by the two optical display systems are consistent.

[0078] Obviously, when the FOV of the two eyes of the NED device is inconsistent, Figure 1 The provided method is used to adjust the sizes of the display images of the two optical display systems to be consistent, that is, to achieve consistency compensation of the binocular FOV of the NED device. Without changing the hardware parameters of the NED device display screen and the optical system, the consistency of the FOV of the binocular display image of the NED device is ensured.

[0079] The above-mentioned binocular FOV consistency compensation method of NED device is simple and easy to operate, and can improve the consistency of binocular FOV. It can also ensure the consistency of displayed content, so that when users watch virtual images, the images seen by the left and right eyes are exactly the same, further enhancing the user's sense of immersion and reality, and has broad application prospects.

[0082] A target FOV determination module 320 is used to determine a target FOV when the two FOVs of the two optical display systems are inconsistent; the target FOV is less than or equal to any one of the two FOVs;

[0083] The display adjustment module 330 is used to determine the display resolution adjustment values ​​of the two optical display systems according to the target FOV, the two FOVs and the two display resolutions, respectively; wherein the ratio of the display resolution adjustment value of each optical display system to the display resolution is equal to the ratio of the target FOV to the FOV of the corresponding optical display system; if the display resolution adjustment value of any optical display system is smaller than its display resolution, the size of the picture to be displayed by the optical display system is interpolated according to the display resolution adjustment value, so that the optical display system displays the picture after the size interpolation.

[0084] Optionally, the display adjustment module 330 is further configured to control pixels outside a pixel region corresponding to a display resolution adjustment value to not emit light when the optical display system displays the size-interpolated picture.

[0085] Further optionally, if the display resolution adjustment value of the optical display system is equal to its display resolution, the display adjustment module 330 does not adjust the picture to be displayed by the optical display system.

[0086] For example, the target FOV may be the smallest FOV of the two FOVs.
