[0002] In AR / VR / MR head-mounted displays, the optomechanical module plays a crucial role. This module projects images of the virtual world, which can be either two-dimensional or three-dimensional. While wearing the device, the human eye can intuitively observe the virtual world. The image quality of the images projected by the optomechanical module must provide the wearer with a comfortable and immersive experience to ensure prolonged wear of the AR / VR / MR head-mounted display.

[0046] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application.

[0047] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0048] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0049] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0050] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0051] The present application provides a test device that simulates the human eye. The test device is used to analyze the image quality displayed by XR display devices (extended reality, including AR augmented reality and VR virtual reality, etc.), where the analysis items include but are not limited to distortion testing, MTF modulation, contrast, color difference, brightness detection, etc. of the binocular fusion image.

[0052] Reference Figure 1 The test equipment for simulating human eyes includes: two human eye-like cameras 1, and the rotation centers of the two human eye-like cameras 1 are located on the same horizontal line.

[0053] Each of the human-eye-like cameras 1 is connected to a first rotation shaft 20, and the first rotation shaft 20 drives the human-eye-like camera 1 to rotate in a vertical direction; each of the human-eye-like cameras 1 is connected to a second rotation shaft 30, and the second rotation shaft 30 drives the human-eye-like camera 1 to rotate in a horizontal direction;

[0054] The first rotation axis 20 is located above the second rotation axis 30 and the first rotation axis 20 is perpendicular to the second rotation axis 30 .

[0055] In this embodiment, the test equipment includes two human-eye-like cameras 1, one simulating the left eye and the other simulating the right eye. Both cameras simulate the human eye's imaging optical path to capture the content or image displayed by the XR display device. This simulation of the different perspectives of the human eye is primarily used to evaluate the device's display quality and user experience.

[0056] The human-eye-like camera 1 simulates the rotation of the human eye. For example, the rotation center of the human-eye-like camera 1 is aligned with the rotation center of the human eye, enabling the camera 1 to simulate the rotation of the human eye. For example, along the optical axis, the distance between the rotation center of the human-eye-like camera 1 and the frontmost lens of the human-eye-like camera 1 can be limited to 13mm to 15mm, to meet the distance between the rotation center of the human eye and the anterior surface of the cornea of most wearers. Preferably, the distance between the rotation center of the human-eye-like camera 1 and the frontmost lens of the human-eye-like camera 1 can be limited to 13.5mm.

[0057] In order to enable the human eye-like cameras 1 to simulate the rotation of human eyes, each human eye-like camera 1 is connected to the first rotation axis 20 and the second rotation axis 30. It should be noted that each human eye-like camera 1 can be directly or indirectly connected to the first rotation axis 20, and each human eye-like camera 1 can be directly or indirectly connected to the second rotation axis 30.

[0058] For a single human-eye-like camera 1, the first rotation axis 20 is used to adjust the pitch angle of the human-eye-like camera 1, that is, the rotation angle of the human-eye-like camera 1 in the vertical direction (indicated by arrow b), simulating the image the wearer sees when looking up or down. The second rotation axis 30 is used to adjust the rotation angle of the human-eye-like camera 1 in the horizontal direction (indicated by arrow a), simulating the image the wearer sees from a horizontal perspective.

[0059] Exemplarily, when the human eye-like camera 1 rotates left or right, the first rotation shaft 20 does not rotate at all, and the second rotation shaft 30 drives the human eye-like camera 1 to rotate at a corresponding angle and direction (counterclockwise or clockwise).

[0060] Exemplarily, when the human eye-like camera 1 rotates upward or downward, the second rotation shaft 30 does not rotate at all, and the first rotation shaft 20 drives the human eye-like camera 1 to rotate at a corresponding angle and direction (clockwise and counterclockwise).

[0061] For example, when the human eye-like camera 1 rotates in an oblique direction such as the upper left direction, both the first rotation axis 20 and the second rotation axis 30 drive the human eye-like camera 1 to rotate in a corresponding angle and direction.

[0062] That is to say, the first rotating shaft 20 and the second rotating shaft 30 drive the human eye-like camera 1 to rotate in different directions.

[0063] In this embodiment, the positional relationship between the first rotation axis 20 and the second rotation axis 30 is also defined. Specifically, the first rotation axis 20 is located above the second rotation axis 30, and the two are arranged perpendicularly. When the first rotation axis 20 is located above the second rotation axis 30, and the two are arranged perpendicularly, the first rotation axis 20 and / or the second rotation axis 30 can rotate the human-eye-like camera 1 in multiple directions when driving the human-eye-like camera 1 to rotate about the rotation center of the human-eye-like camera 1.

[0064] Therefore, in this embodiment, the test equipment can simulate the imaging effect when the wearer wears the device to be tested with both eyes, and drive the human eye-like camera 1 to simulate the rotation of the human eye through the cooperation of the first rotating axis 20 and the second rotating axis 30, thereby improving the accuracy of the test equipment in analyzing the image of the XR test equipment.

[0065] Preferably, the axis of the first rotating shaft 20 is collinear with the rotation center of the human eye-like camera 1, and the axial direction of the second rotating shaft 30 is collinear with the rotation center of the human eye-like camera 1, so that the rotation trajectory of the human eye-like camera 1 is more consistent with the rotation trajectory of the human eye.

[0066] In one embodiment, the vertical height difference between the first rotating shaft 20 and the second rotating shaft 30 ranges from 50 mm to 90 mm.

[0067] In this embodiment, the vertical height range of the first rotating shaft 20 and the second rotating shaft 30 is limited, so that the human-eye-like camera 1 will not interfere with its components during the rotation process, especially the human-eye-like camera 1 will not interfere with the mounting bracket 6 of the test equipment during the downward rotation process (the mounting bracket 6 realizes the installation of the human-eye-like camera 1, the first rotating shaft 20 and the second rotating shaft 30).

[0068] Specifically, based on the rotation range of the human eye-like camera 1 and the compactness of the test equipment structure, the vertical heights of the first rotation axis 20 and the second rotation axis 30 can be adjusted without affecting the rotation effect of the human eye-like camera 1 to make the overall structure of the test equipment more compact.

[0069] In one embodiment, referring to Figure 1 , the two first rotation axes 20 are located on the same horizontal line, and the two second rotation axes 30 are arranged in parallel.

[0070] Exemplarily, the test device includes two human eye-like cameras 1, specifically a first human eye camera 10 and a second human eye camera 11. The first human eye camera 10 simulates a human right eye, and the second human eye camera 11 simulates a human left eye.

[0071] Reference Figure 1 For the first type of human eye camera 10, a first rotation axis 20 is provided on the side of the first type of human eye camera 10 facing away from the second type of human eye camera 11 (the right side of the first type of human eye camera 10), and the axis of the first rotation axis 20 is collinear with the rotation center of the first type of human eye camera 10.

[0072] For the second type of human eye camera 11, another first rotation axis 20 is set on the side of the second type of human eye camera 11 away from the first type of human eye camera 10 (the left side of the second type of human eye camera 11), and the axis of the first rotation axis 20 is collinear with the rotation center of the second type of human eye camera 11.

[0073] When the rotation centers of the two human-eye-like cameras 1 are collinear, the two first rotation axes 20 are located on the same horizontal line. This allows the two human-eye-like cameras 1 to rotate about their rotation axes while maintaining their rotation centers. The visual focus (i.e., the rotation center) of the human-eye-like cameras 1 will not shift during rotation, thereby ensuring continuity and stability in visual capture and enabling the human-eye-like cameras 1 to capture images with greater precision and accuracy.

[0074] Reference Figure 1For the first type of human eye camera 10 , a second rotation axis 30 is set below the first type of human eye camera 10 , and the axis of the second rotation axis 30 is collinear with the rotation center of the first type of human eye camera 10 .

[0075] For the second type human eye camera 11 , another second rotation shaft 30 is provided below the second type human eye camera 11 , and the axis of the second rotation shaft 30 is collinear with the rotation center of the second type human eye camera 11 .

[0076] The parallel arrangement of the second rotation axes 30 facilitates motion coordination between the two human-eye-like cameras 1. When the two second rotation axes 30 are parallel, it is easier to achieve synchronous rotation or relative rotation of the two human-eye-like cameras 1, thereby ensuring that the human-eye-like cameras 1 maintain a consistent visual direction and angle when capturing images.

[0077] In one embodiment, the vertical rotation angle range of the human eye-like camera 1 is: -57° to 42°; and / or the horizontal rotation angle range of the human eye-like camera 1 is: -42° to 82°.

[0078] Specifically, the natural rotation range of the human eye in the vertical direction is limited. This embodiment specifically sets the vertical rotation angle range of the human eye-like camera 1 to -57° to 42°, which can better simulate the natural state of the human eye when looking up and down, while avoiding visual distortion or mechanical structure pressure caused by excessive rotation.

[0079] In the horizontal direction, setting the rotation range from -42° to 82° can ensure that the human-eye camera 1 has a wider field of view coverage. This rotation range can provide a more natural visual experience and reduce the user's visual fatigue and discomfort.

[0080] In one embodiment, referring to Figure 1 The horizontal distance between the two human eye-like cameras 1 is 50 mm to 75 mm.

[0081] In this embodiment, the interpupillary distance (i.e., the distance between the pupils) of the human eye varies from person to person. By setting the horizontal distance between the two human-eye-like cameras 1 to 50mm to 75mm, this range covers the interpupillary distance range of most people. Therefore, the test device can more accurately simulate the visual experience of wearers with different interpupillary distances when using an XR display device.

[0082] In one embodiment, the motion trajectories of the two human eye-like cameras 1 include: motion in the same direction or motion in different directions.

[0083] Exemplarily, the motion trajectories of the first type human eye camera 10 and the second type human eye camera 11 may be in the same direction, for example, the two cameras may turn right together, turn left together, turn up together, or turn down together.

[0084] Exemplarily, the motion trajectories of the first type of human eye camera 10 and the second type of human eye camera 11 can be different directional movements, such as the inward rotation of the two when looking from a distance to a near object, the movement of the two sights apart to the sides, and the simultaneous rotation of the two inwards (simulating the movement trajectory of the human eye toward the side of the nose).

[0085] In this embodiment, the motion trajectories of the first type human eye camera 10 and the second type human eye camera 11 are defined, and the motion trajectories of the two human eye-like cameras 1 conform to the binocular motion trajectories of the human eye.

[0086] In one embodiment, the two first rotating shafts 20 are electrically connected to the first motor, and the two second rotating shafts 30 are electrically connected to the second motor; or, the two first rotating shafts 20 are electrically connected to the third motor and the fourth motor, respectively, and the two second rotating shafts 30 are electrically connected to the fifth motor and the sixth motor, respectively.

[0087] In an example, the first rotating shaft 20 connected to the first type of human eye camera 10 and the second type of human eye camera 11 respectively are connected to the same first motor, and the rotation of the first type of human eye camera 10 and the second type of human eye camera 11 in the vertical direction can achieve a high degree of synchronization to simulate the movement trajectory of the human eye.

[0088] The second rotating shaft 30 connected to the first type of human eye camera 10 and the second type of human eye camera 11 respectively is connected to the same second motor, and the horizontal rotation of the first type of human eye camera 10 and the second type of human eye camera 11 can achieve a high degree of synchronization to simulate the movement trajectory of the human eye.

[0089] In another example, the first rotating shaft 20 connected to the first type of human eye camera 10 and the first rotating shaft 20 connected to the second type of human eye camera 11 are respectively connected to two different motors. Such independent control allows more precise adjustment of the vertical rotation of each human eye-like camera 1, thereby meeting the different rotation trajectory requirements of the human eye.

[0090] For example, the first rotating shaft 20 connected to the first type of human eye camera 10 is connected to the third motor, and the first rotating shaft 20 connected to the second type of human eye camera 11 is connected to the fourth motor. Figure 1The third motor serves as the first drive component 21 of the first-type human eye camera 10. The fourth motor serves as the first drive component 21 of the second-type human eye camera 11. The first drive component 21 can be a rotary motor, a stepper motor, or another type of motor. In other words, the first rotating shaft 20 and the first drive component 21 constitute the first drive assembly 2, which is electrically connected to the human eye-like camera 1 to drive the human eye-like camera 1 to rotate vertically.

[0091] The second rotating shaft 30 connected to the first type of human eye camera 10 and the second rotating shaft 30 connected to the second type of human eye camera 11 are respectively connected to two different motors. Such independent control allows more precise adjustment of the horizontal rotation of each human eye-like camera 1, thereby meeting higher precision requirements.

[0092] For example, the second rotating shaft 30 connected to the first type human eye camera 10 is connected to the fifth motor, and the second rotating shaft 30 connected to the second type human eye camera 11 is connected to the sixth motor. Figure 1 The fifth motor serves as the second drive component 31 of the first-type human eye camera 10. The sixth motor serves as the second drive component 31 of the second-type human eye camera 11. The second drive component 31 can be a rotary motor, a stepper motor, or another type of motor. In other words, the second rotating shaft 30 and the second drive component 31 constitute the second drive assembly 3, which is electrically connected to the human eye-like camera 1 to drive the human eye-like camera 1 to rotate horizontally.

[0093] In one embodiment, referring to Figure 1 and Figure 2 The test equipment simulating the human eye also includes a camera bracket 5, and the human eye-like camera 1 includes a cornea-like lens; the human eye-like camera 1 is fixedly connected to the camera bracket 5, and the cornea-like lens is arranged away from the camera bracket 5.

[0094] In this embodiment, the camera bracket 5 serves as an important component for supporting and fixing the human eye-like camera 1 , thereby ensuring the stability and accuracy of the human eye-like camera 1 during the test process.

[0095] The human eye-like camera 1 is used to simulate the visual function of the human eye. The human eye-like camera may contain complex components such as sensors and image processing algorithms to capture and process image information. These components can be built into the camera bracket 5.

[0096] To enable the human-eye-like camera 1 to better simulate the human eye in capturing images, it includes a cornea-like lens. This lens is a key component that mimics the optical properties of the human cornea. Located at the front end of the human-eye-like camera 1, it receives and focuses light to produce a clear image. The material, shape, and optical properties of the cornea-like lens significantly impact the image quality and field of view of the human-eye-like camera. Those skilled in the art can select a cornea-like lens that meets the parameters of the human eye based on actual needs.

[0097] In this embodiment, by introducing the cornea-like lens and the camera bracket 5, the testing device can simulate an imaging effect that is closer to that of the human eye, thereby improving the accuracy and reliability of the test.

[0098] In a further embodiment, referring to Figure 2 The human eye-like camera 1 is provided with a connecting hole 12 , and the camera bracket 5 is provided with a connecting column 51 , and the connecting column 51 is embedded in the connecting hole 12 .

[0099] In this embodiment, in order to achieve the connection between the human eye-like camera 1 and the camera bracket 5, a connecting hole 12 is opened on the human eye-like camera 1, and correspondingly, a connecting column 51 is set on the camera bracket 5. Through the cooperation of the connecting hole 12 and the connecting column 51, the camera bracket 5 and the human eye-like camera 1 are connected together.

[0100] For example, referring to Figure 2 A plurality of connection holes 12 are opened around the human eye-like camera 1, and correspondingly, a plurality of connection columns 51 are set around the camera bracket 5. The connection columns 51 and the connection holes 12 cooperate to improve the reliability of the connection between the two.

[0101] For example, the connecting posts 51 provided on the camera bracket 5 generally have a certain length and diameter to ensure that they can be firmly inserted into the connecting holes 12 and provide sufficient support. The surface of the connecting posts 51 can be specially treated, such as threading, chamfering or coating, to enhance the stability and durability of the connection.

[0102] In addition, an avoidance portion may be provided between adjacent connecting columns 51 to prevent the design of the camera bracket 5 from affecting the effect of the human eye-like camera 1 in capturing images.

[0103] It should be noted that, in addition to simple embedding, additional fixing mechanisms such as screws, buckles or locking devices may be designed between the connecting hole 12 and the connecting column 51 to ensure that the human eye-like camera 1 will not loosen during rotation or use.

[0104] In a further embodiment, referring to Figure 2 , the connecting hole 12 is aligned with the rotation center of the human eye-like camera 1.

[0105] In this embodiment, a connection hole 12 is provided on the human eye-like camera 1. By aligning the connection hole 12 with the rotation center of the human eye-like camera 1, the rotation angle and range of the human eye-like camera 1 can be precisely controlled, thereby meeting the different rotation trajectory requirements of the human eye.

[0106] In one embodiment, referring to Figure 1 The test equipment simulating the human eye also includes a third driving component 4 for adjusting the horizontal distance between the two human eye-like cameras 1.

[0107] In this embodiment, the test equipment simulating the human eye includes a first type of human eye camera 10 and a second type of human eye camera 11. The horizontal spacing between the first type of human eye camera 10 and the second type of human eye camera 11 is adjustable to adapt to different pupil distances of different wearers' eyes.

[0108] Specifically, by adjusting the horizontal spacing between the first and second eye-like cameras 10 and 11 by the third drive assembly 4, the test device can simulate wearers with different pupil distances to test the image quality of the XR display device in various situations. In other words, the test device can analyze images captured by eye-like cameras at different spacings.

[0109] In one embodiment, referring to Figure 1 The third driving assembly 4 includes a base 40 and a base fitting 41, and the base fitting 41 is sleeved on the outside of the second rotating shaft 30;

[0110] The base 40 is provided with a slide assembly 42 , and the base fitting 41 is slidably disposed in the slide assembly 42 .

[0111] In this embodiment, the third drive assembly 4 includes a base 40 and a base fitting 41. The base 40 is a fixed part that provides support and stability. The base fitting 41 is a movable part that cooperates with the base 40 to adjust the spacing.

[0112] Specifically, the base fitting 41 is sleeved on the outside of the second rotation shaft 30. When the second driving component 31 drives the second rotation shaft 30 to rotate, the base fitting 41 is U-shaped and buckled onto the second driving component 31, and the second rotation shaft 30 passes through the base fitting 41 and extends from the base fitting 41 to drive the human eye-like camera 1 to rotate.

[0113] The base 40 is provided with a slide assembly 42. The slide assembly 42 can be a series of parallel grooves or tracks for guiding the movement of the base fitting 41. The design of the slide assembly 42 allows the base fitting 41 to slide horizontally, thereby adjusting the horizontal spacing between the two human eye-like cameras 1.

[0114] In this embodiment, the slide assembly 42 provides a clear movement path and restriction, preventing the base fitting 41 from accidentally shifting or shaking, and ensuring the stability of the distance adjustment between the two human eye-like cameras 1.

[0115] In one embodiment, referring to Figure 1 The base 40 is provided with two slide groove components 42, one of the slide groove components 42 cooperates with one of the base fittings 41 to enable one of the human eye-like cameras 1 to slide; the other slide groove component 42 cooperates with the other base fitting 41 to enable the other human eye-like camera 1 to slide.

[0116] In this embodiment, the human eye-simulating test device includes two independently arranged base fittings 41, each of which is associated with a human eye-like camera 1. Two independent slide assemblies 42 are defined on the base 40, each designed to mate with a base fitting 41. These two slide assemblies 42 are arranged parallel to each other on the base 40 to ensure that the two human eye-like cameras 1 can slide horizontally.

[0117] The first slide assembly 42 cooperates with the first base fitting 41 to enable the sliding of the first human-eye-like camera 1 (e.g., the first human-eye-like camera 10). The second slide assembly 42 cooperates with the second base fitting 41 to enable the sliding of the second human-eye-like camera (e.g., the second human-eye-like camera 11). Specifically, by moving the positions of the two base fittings 41 within their respective slide assemblies 42, the spacing between the two human-eye-like cameras 1 can be adjusted. This adjustment can be manual or automated using some mechanical or electrical device.

[0118] For example, a scale mark may be provided on the base 40 so that the user can more accurately adjust the horizontal distance between the two human eye-like cameras 1 .

[0119] In one embodiment, referring to Figure 1 Each of the chute components 42 includes a first chute 421 and a second chute 422, wherein the first chute 421 and the second chute 422 are arranged along a third direction, and the third direction, the horizontal direction, and the vertical direction are perpendicular to each other;

[0120] One side of the base fitting 41 is disposed in the first sliding groove 421 , and the other side of the base fitting 41 is disposed in the second sliding groove 422 .

[0121] In this embodiment, each slide assembly 42 is composed of two independent parts, a first slide 421 and a second slide 422. The first slide 421 and the second slide 422 are arranged in parallel on the base 40 to provide stable guidance and support.

[0122] One side of the base fitting 41 is placed in the first sliding groove 421, while the other side is embedded in the second sliding groove 422. This double-groove matching design significantly enhances the stability and accuracy of the base fitting 41 during the sliding process.

[0123] In one embodiment, referring to Figure 1 The center lines of the two first sliding grooves 421 along the sliding direction are on the same horizontal line, and the center lines of the two second sliding grooves 422 along the sliding direction are on the same horizontal line.

[0124] In this embodiment, the centerlines of the two first chutes 421 along the sliding direction are designed to be on the same horizontal line, and the centerlines of the two second chutes 422 along the sliding direction are also designed to be on the same horizontal line. This ensures that the base mating component 41, which cooperates with the chute assembly 42 (the first chute 421 and the second chute 422), maintains horizontal stability during sliding. Regardless of the position of the base mating component 41 within the chute, the supporting force on both sides is balanced, thus preventing tilting or deviation during sliding.

[0125] In one embodiment, referring to Figure 1 and Figure 2 , the distance between the two first chutes 421 is less than or equal to 50 mm, and the distance between the two second chutes 422 is less than or equal to 50 mm;

[0126] The first slide groove 421 has a first end face 4211 farthest from the other first slide groove 421, and the distance between the two first end faces 4211 is greater than 75 mm, and the second slide groove 422 has a second end face 4221 farthest from the other second slide groove 422, and the distance between the two second end faces 4221 is greater than 75 mm.

[0127] In this embodiment, the minimum spacing distance between the two first slide grooves 421 and the maximum spacing distance between the two first slide grooves 421 are limited, and the minimum spacing distance between the two second slide grooves 422 and the maximum spacing distance between the two second slide grooves 422 are limited, ensuring that the horizontal spacing between the first type of human eye camera 10 and the second type of human eye camera 11 can be adjusted between 50 mm and 75 mm.

[0128] In an alternative embodiment, referring to Figure 1The base fitting 41 has a U-shaped structure, and the base fitting 41 is buckled on the second driving component 31 . One side of the base fitting 41 is arranged in the first sliding groove 421 , and the other side of the base fitting 41 is arranged in the second sliding groove 422 .

[0129] Each side of the base fitting 41 has a first region and a second region arranged in a vertical direction. The second region is formed with a protrusion 411, which protrudes from the edge of the slideway of the slideway assembly 42. In this way, when the base fitting 41 slides in the slideway, the protrusion 411 and the edge of the slideway act as a limiter, preventing the base fitting 41 from tilting or deflecting during the sliding process.

[0130] In an alternative embodiment, referring to Figure 1 The human eye simulating test device further includes a mounting bracket 6, a camera bracket 5 rotatably connected to the mounting bracket 6, and a first rotation axis 20 connected to the camera bracket 5. Driven by the first rotation axis 20, the camera bracket 5 rotates relative to the mounting bracket 6, thereby achieving rotation of the human eye-like camera 1 on the camera bracket 5.

[0131] The connection method between the camera bracket 5 and the mounting bracket 6 is as follows:

[0132] Reference Figure 1 A first positioning hole 511 is provided on the connecting column 51 of the camera bracket 5, and the mounting bracket 6 includes a first bracket, which has a second positioning hole 61 corresponding to the first positioning hole 511; the test equipment also includes a connecting shaft 62, one end of the connecting shaft 62 is rotatably disposed in the second positioning hole 61, and the other end of the connecting shaft 62 is rotatably disposed in the first positioning hole 511, thereby realizing the vertical rotation of the human eye-like camera 1 relative to the mounting bracket 6.

[0133] Further, refer to Figure 1 The mounting bracket 6 includes a second bracket, which is arranged opposite to the first bracket; the first rotating shaft 20 passes through the second bracket and is connected to the camera bracket 5, and the first rotating shaft 20 is colinear with the connecting shaft 62.

[0134] Further, refer to Figure 1 The mounting bracket 6 also includes a third bracket, which is located below the first bracket and the second bracket, and the first bracket and the second bracket are respectively connected to the third bracket; the second rotating shaft 30 passes through the third bracket to drive the mounting bracket 6 to rotate.

[0135] In a second aspect, an embodiment of the present application further provides a test system for simulating a human eye. The test system for simulating a human eye comprises:

[0136] The test device simulating a human eye as described in the first aspect, wherein the test device simulating a human eye is used to obtain image information of a device to be tested;

[0137] a signal processing device for receiving image information acquired by the test device simulating a human eye;

[0138] The result analysis device analyzes the device to be tested based on the motion data of the human eye-like camera 1 and the image information transmitted thereto by the signal processing device.

[0139] In this embodiment, the test device simulating the human eye is used to simulate the imaging effect of a wearer wearing an XR display device (device to be tested). Specifically, image information of the XR display device is obtained through two human eye-like cameras 1.

[0140] The signal processing device receives image information from the eye-simulating test equipment. This device may include an FPGA module. After receiving the image information, the signal processing device performs preprocessing, including but not limited to denoising, enhancement, and compression. These processing steps help improve image quality and provide more valuable data for subsequent analysis.

[0141] The result analysis device uses the motion data of the human eye camera 1 and the image information transmitted by the signal processing device to conduct a comprehensive and in-depth analysis of the device to be tested. Through analysis, the result analysis device can evaluate the performance, user experience, compatibility and other aspects of the device to be tested. For example, the result analysis device can be an external device (such as a computer, etc.) or a built-in module of the test device. By simulating the human binocular vision system, the system can more realistically reflect the performance of the device to be tested in actual use.
