[0041] Figure 2 This is a schematic diagram of the structure of a calibration system for AR glasses provided in an embodiment of this application. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Please see below. Figure 1 , Figure 1 This is a flowchart illustrating a calibration method for AR glasses provided in an embodiment of this application.

[0044] Specific steps may include:

[0045] S101: Collect the wearer's eye data and determine the gaze position and gaze angle based on the eye data;

[0046] This embodiment can be applied to the processing chip of AR glasses, or to control devices connected to AR glasses. This embodiment can collect user eye data (such as eye position, pupil position, gaze direction, and distance from the glasses to the screen) using a camera or sensor, and then determine the user's gaze position and gaze angle based on the collected eye data.

[0047] As one feasible implementation, this step can be based on collecting eye data using an eye-tracking device to determine the gaze position and gaze angle. Specifically, the eye-tracking device emits infrared light to illuminate the surface of the eye, and then determines the eye data (i.e., eye-tracking data) based on the reflected light. Based on the eye-tracking data, the location of the user's gaze focus (i.e., gaze position) and the angle of the user's line of sight relative to a reference plane (such as the plane of the lens) (i.e., gaze angle) can be determined.

[0048] S102: Determine the wearer's visual range through visual measurement;

[0049] This step can utilize a camera or other visual sensing devices to assess and quantify the visual range that a user wearing AR glasses can perceive. For example, in this embodiment, a camera can be used to capture the wearer's eye rotation limit position and pupil size information when observing a test scene. Based on the eye rotation limit position and pupil size information, the wearer's maximum horizontal viewing angle, maximum vertical viewing angle, and stereoscopic depth range can be calculated. The wearer's visual range can be determined based on the maximum horizontal viewing angle, maximum vertical viewing angle, and stereoscopic depth range.

[0050] S103: Determine the visual field boundary of the wearer on the lens based on the gaze position, gaze angle and visual range, and set the area within the visual field boundary as the current visible area;

[0051] In this embodiment, image processing calculations are performed on the gaze position, gaze angle, and visual range to obtain the wearer's visual field boundary on the lens. The visual field boundary is the boundary line of the maximum range that the wearer can clearly see through the lens, that is, the limit of the farthest boundary that the line of sight can reach.

[0052] After determining the visual field boundary, the area on the lens within the aforementioned visual field boundary can be set as the current visible area. Since the wearer's gaze position and visual range may change over time, this embodiment can update the wearer's current visible area according to a preset period.

[0053] S104: Set the area where the virtual content currently displayed on the lens is located as the initial display area, and compare the initial display area with the current visible area to obtain the comparison result;

[0054] Prior to this step, there may be an operation to display virtual content on the lens. In this embodiment, the area where the currently displayed virtual content is located on the lens can be set as the initial display area. After determining the initial display area and the current visible area, the initial display area and the current visible area can be compared to obtain the difference between the initial display area and the current visible area, i.e., the comparison result.

[0055] Specifically, this embodiment can compare the position of the initial display area and the current visible area to obtain the position comparison result; this embodiment can also compare the size of the initial display area and the current visible area to obtain the size comparison result.

[0056] This step compares the initial display area with the current visible area, which helps determine the relationship between the virtual content and the wearer's field of vision, and optimizes display parameters accordingly to improve the user experience.

[0057] S105: Adjust the display parameters of the virtual content according to the comparison results.

[0058] In this embodiment, the comparison results can be analyzed to determine the deviation between the initial display area and the current visible area, and then the display parameters of the virtual content can be adjusted based on the deviation so that the virtual content after adjusting the display parameters is appropriately displayed in the wearer's field of vision.

[0059] This embodiment collects the wearer's eye data to determine the gaze position and angle, and also determines the wearer's visual range through visual measurements. Then, combining the gaze position, gaze angle, and visual range, it determines the wearer's actual current visible area on the lens. This embodiment compares the current visible area with the initial display area of ​​the virtual content displayed on the lens to obtain a comparison result. Based on the comparison result, the positional deviation and / or size deviation between the currently displayed virtual content area and the current visible area can be determined. Based on the aforementioned positional deviation and / or size deviation, the display parameters of the virtual content can be adjusted to ensure the matching of the virtual content with the current visible area. This method dynamically optimizes the display parameters of the virtual content, reduces visual discomfort and information loss, allows virtual images to blend more naturally into the user's real environment, enhances the realism of the image display and user acceptance, and improves the image display quality of AR glasses.

[0060] As for Figure 1In a further description of the corresponding embodiment, if the comparison result includes a position comparison result, the display position in the virtual content display parameters can be adjusted in the following ways:

[0061] The center point position deviation value is determined based on the position comparison result, and the display position of the virtual content is adjusted according to the center point position deviation value so that the display position of the center point of the virtual content is the center of the current visible area.

[0062] Specifically, this embodiment calculates the difference between the center point of the initial display area and the center point of the current visible area to obtain the center point position deviation value. After determining the center point position deviation value, this embodiment can adjust the display position of the virtual content according to the center point position deviation value, so that the virtual content is in the center of the current visible area.

[0063] As for Figure 1 In a further description of the corresponding embodiment, if the comparison result includes a size comparison result, the resolution in the virtual content display parameters can be adjusted in the following ways:

[0064] Based on the size comparison result, a resolution deviation value is determined, and the resolution of the virtual content is adjusted according to the resolution deviation value so that the resolution of the virtual content matches the size of the current visible area.

[0065] Specifically, this embodiment calculates the difference between the initial display area size and the current viewable area size to obtain the resolution difference. After determining the resolution difference, this embodiment adjusts the resolution of the virtual content based on the resolution difference to ensure that the virtual content is displayed with optimal quality within the current viewable area. This method improves the clarity of the virtual content and reduces image distortion and blurring.

[0066] As for Figure 1 As further described in the corresponding embodiment, this embodiment can generate a corresponding display effect image based on the virtual content; compare the color of the display effect image with a preset image, and calibrate the color profile of the AR glasses based on the color comparison result.

[0067] In this embodiment, a display effect diagram can be generated based on the attributes of the virtual content (such as resolution, color depth, texture, etc.) and the display parameters of the AR glasses. The display effect diagram is used to simulate the display effect of the virtual content in the AR glasses. This embodiment can also select a color card or color test pattern as a preset image and compare it with the display effect diagram to obtain a color comparison result. Based on the color comparison result, the color difference between the display effect diagram and the preset image can be determined. This embodiment can reduce these differences by modifying parameters in the color configuration file (such as brightness, contrast, saturation, or color temperature) to achieve color calibration.

[0068] As for Figure 1 In a further description of the corresponding embodiment, the brightness of the AR glasses can also be adjusted in the following ways:

[0069] The system detects the scene type of the wearer's location; determines whether the scene type is a preset scene; if so, it queries the preset brightness value corresponding to the preset scene and adjusts the current brightness of the AR glasses according to the preset brightness value; if not, it collects environmental information and adjusts the current brightness of the AR glasses according to the environmental information; wherein, the environmental information includes ambient light intensity and / or light intensity change rate.

[0070] The aforementioned preset scenarios can be scenarios with predetermined preset brightness values, such as movie theaters, study rooms, and subways. This embodiment can determine the scenario type of the wearer based on location information and surrounding environment images. If the scenario type is a preset scenario, the current brightness of the AR glasses can be set to the preset brightness value corresponding to that scenario. If the scenario type is not a preset scenario, this embodiment can adaptively adjust the current brightness of the AR glasses based on environmental information.

[0071] As for Figure 1 In a further description of the corresponding embodiment, this embodiment can adjust the current brightness of the AR glasses according to the environmental information in the following way: if the environmental information includes the ambient light intensity and the light intensity change rate, then a light intensity prediction curve is generated according to the ambient light intensity and the light intensity change rate; wherein, the light intensity prediction curve is used to describe the correspondence between time and ambient light intensity; a corresponding brightness control curve is generated according to the light intensity prediction curve, and the current brightness of the AR glasses is adjusted according to the brightness control curve.

[0072] This embodiment generates a light intensity prediction curve by combining ambient light intensity and light intensity change rate, and adjusts the brightness of AR glasses accordingly. This not only improves the comfort and naturalness of the user experience, but also enhances the fusion effect of reality and virtual content.

[0073] As for Figure 1Further description of the corresponding embodiment suggests that the refresh rate of the AR glasses can also be adjusted in the following way: determining whether the wearer is in motion; if so, calculating the wearer's head movement speed and hand movement speed, and adjusting the refresh rate of the AR glasses based on the head movement speed and hand movement speed. Specifically, in this embodiment, the refresh rate of the AR glasses can be obtained by weighted calculation of head movement speed and hand movement speed, where head movement speed and hand movement speed are positively correlated.

[0074] In this embodiment, after obtaining the head and hand movement speeds, the refresh rate of the AR glasses can be adjusted based on these speeds. When the head and hand movement speeds are fast, a higher refresh rate is needed to maintain smoothness and avoid motion blur or lag. When the head and hand movement speeds are slow, the refresh rate can be reduced to save energy and extend the device's lifespan.

[0075] The process described in the above embodiments is illustrated below through examples in practical applications.

[0076] AR glasses use a series of optical imaging elements to form a distant virtual image and project it into the user's eyes. Currently, AR glasses undergo rigorous testing before leaving the factory, including simulating user wearing, adjusting interpupillary distance, and refractive power, to ensure satisfactory clarity and comfort for the user. However, even after these mechanical calibrations, AR glasses still cannot achieve optimal clarity.

[0077] To address the technical problems existing in the aforementioned related technologies, this embodiment provides an AR glasses testing and calibration method, specifically including the following steps:

[0078] Step A1: Preheat the AR glasses.

[0079] This step ensures that the AR glasses have been turned on for a period of time so that they can reach a stable working state.

[0080] Step A2: Adjust the brightness.

[0081] This step allows you to adjust the brightness settings of the AR glasses to suit the current indoor lighting environment. If the AR glasses are too bright or too dark, it may affect visual comfort and image accuracy.

[0082] Step A3: Adjust the contrast.

[0083] Contrast ratio is the relative brightness difference between the brightest white and the darkest black on AR glasses. Adjusting the contrast ratio yields the best image clarity and detail.

[0084] Step A4: Pixel calibration.

[0085] Pixel calibration ensures color consistency across different devices, improving image visibility. Reference objects such as standard color charts or grayscale charts can be used during the calibration process.

[0086] Step A5: Calibrate the colors.

[0087] This embodiment can be calibrated using a color calibration instrument to ensure that the AR glasses display colors accurately. This typically involves adjusting the AR glasses' color profile to match standard color specifications.

[0088] Step A6: Adjust the resolution.

[0089] Resolution determines the number of pixels on AR glasses, affecting image clarity and detail. This embodiment allows you to select an appropriate resolution to achieve the best viewing experience based on the image or video content to be displayed.

[0090] Step A7: Anti-aliasing settings.

[0091] Anti-aliasing is an image processing technique used to reduce the jagged edges of an image. By adjusting the anti-aliasing level, image edges can be made smoother and distortion reduced.

[0092] Step A8: Adjust the refresh rate.

[0093] The refresh rate determines how many times the AR glasses update the image per second. For content that requires a high frame rate, such as dynamic images or games, adjusting to a higher refresh rate can result in a smoother visual experience.

[0094] The binocular display system used in AR glasses follows the natural binocular imaging principle of the human eye. It's crucial to avoid misalignment or offset between the images displayed to each eye. Therefore, precise pixel calibration technology is needed to achieve seamless fusion of the images from both eyes. Thus, steps A3-A8 above can be calibrated using a binocular calibration mode. The binocular calibration mode performs factory correction, distortion correction, downsampling (reducing by half), and HDR bracketing on the 3D data output from the VR glasses. Then, it performs online calibration. Once the calibration quality meets the standards, it is input into a stereo CNN network and then into the rendering pipeline to generate coatings, texture repair, meshes, etc. If the calibration quality does not meet the standards, it reverts to monocular calibration mode, inputs the data into a monocular CNN network for processing, and then into the rendering pipeline to generate a new perspective. When one camera is obstructed, or when the feature data captured by the camera is insufficient, the above embodiment can use monocular calibration mode for detection. Whether in binocular or monocular calibration mode, the same downstream processing pipeline is used. The advantage is that it can output high-accuracy relative parallax, which can well meet the purpose of 3D capture and modeling. In addition, after generating the depth parallax map, the system will crop the largest effective area and maintain the original aspect ratio. This can further optimize the overall quality of 3D modeling.

[0095] When performing pixel calibration, this embodiment first determines the image's color space and color profile. The color space determines the range of colors that can be represented in an image, while the color profile defines how these colors are rendered on a specific device. Calibration ensures a closer resemblance to the real scene and improves the image's visual quality. The calibration process typically requires the use of reference objects such as standard color charts or grayscale charts. By photographing these reference objects, a set of baseline data can be obtained, and then the pixel values ​​in the image are adjusted based on this data.

[0096] This embodiment also provides a pixel calibration scheme for AR glasses, including the following steps:

[0097] Step B1: Calibration preparation.

[0098] Before starting pixel calibration, users are asked to adopt a specific posture or look at a specific landmark to ensure that their eyes are in the correct position and posture.

[0099] Step B2: Eye data acquisition.

[0100] AR glasses use built-in cameras or sensors to collect data about the user's eye position, pupil position, gaze direction, and distance from the eyes to the screen. This data is used to calculate pixel calibration parameters.

[0101] Step B3: Visual measurement.

[0102] The cameras or sensors inside the AR glasses measure the visual range of each of the user's eyes and determine the mapped area of ​​each eye on the screen.

[0103] Step B4: Image analysis.

[0104] Based on eye data and visual measurements, the AR glasses' cameras or sensors analyze and transmit the mapping of the user's eyes on the screen to determine the amount of adjustment needed for pixel calibration.

[0105] Step B5: Pixel adjustment.

[0106] Based on the image analysis results, the pixels on the screen are fine-tuned via the AR glasses' system menu to ensure that the position and size of the virtual content in the user's eyes are aligned with the real world. This may involve adjusting the position, size, brightness, or color of pixels.

[0107] Step B6: Calibration Confirmation.

[0108] After the pixel adjustment is completed, the AR glasses will provide users with some feedback so that they can confirm whether the calibration has achieved the expected results.

[0109] When performing binocular calibration, this embodiment can be executed according to steps B1 to B6 above. If the desired result is not achieved after adjustment, monocular calibration mode needs to be used, that is, one side of the AR glasses is blocked and calibration is performed again. After the two display areas of the AR glasses are calibrated separately, binocular observation is then used to observe whether the binocular images achieve seamless fusion during use.

[0110] This embodiment uses pixel calibration technology to assist in the image calibration of VR glasses. Pixel calibration technology is a technique used to adjust and optimize image quality. It corrects the pixel values ​​in the image to make them closer to the colors and details of the real scene. Calibration through pixel calibration technology can ensure the authenticity of the presented image and improve the visual effect and viewing experience of the image.
