[0040] 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.

[0041] Figure 1 This is one of the structural diagrams of the near-eye display imaging detection system provided in the embodiment of the present application. Figure 2 This is the second structural diagram of the near-eye display imaging detection system provided in the embodiment of the present application. Figure 1 and Figure 2 They are side and front diagrams respectively, refer to Figure 1 and Figure 2 The near-eye display imaging detection system includes at least: a bionic eyeball body, a bionic eyeball fixing part, an optical fiber guide bundle and an optical fiber imaging detector.

[0042] The bionic eyeball body is rotatably mounted within the bionic eyeball fixture. Designed to simulate the visual function of the human eye, the bionic eyeball body is configured to receive light from a virtual image projected by a near-eye display device and form an image on the retina. The bionic lens can be implemented using any eyepiece, and by adjusting the focal length, the virtual image projected by the near-eye display device can be clearly projected onto the retina.

[0043] In some embodiments, the bionic eyeball holder is a bionic eyeball frame having a spherical receiving space, and the bionic eyeball body is rotatably mounted within the opening of the bionic eyeball frame. In some embodiments, the bionic eyeball holder is a bionic skull model, and the bionic eyeball body is rotatably mounted within the eye socket of the bionic skull model. In some embodiments, the bionic eyeball holder is a base, and the bionic eyeball body is rotatably mounted on the base.

[0044] The input end of the fiber optic imaging bundle is located at the retina of the bionic eye, rotating with the eye's movement. The output end is connected to a fiber optic imaging detector. Optical fiber (or simply fiber) is a glass fiber that transmits light signals with high quality. When light enters an optically dense medium from an optically sparse medium, the fiber reflects back into the dense medium at the interface, allowing the light signal to be repeatedly reflected within the bundle and transmitted forward. The fiber optic imaging bundle transmits an image of the surface of the object being observed to the observation end.

[0045] In an embodiment of the present application, a fiber optic imaging bundle is configured to transmit a virtual image projected by a near-eye display device onto the retina to a fiber optic imaging detector. The input end of the fiber optic imaging bundle rotates with the rotation of the bionic eye, which simulates the movement of the human eye. The fiber optic imaging bundle transmits the virtual image at the retina to the fiber optic imaging detector.

[0046] The fiber optic imaging detector is disposed at the output end of the optical imaging bundle and is configured to display a secondary image of the virtual image projected by the near-eye display device based on the virtual image transmitted by the fiber optic imaging bundle. The secondary image is subjected to correlation detection, and the detection result can be used as the detection result of the virtual image projected by the near-eye display device, that is, the secondary image is used for performance detection of the near-eye display device. In some embodiments, the fiber optic imaging detector is one or more of an industrial camera, a luminance meter, a colorimeter, or a flicker detector, etc. The flicker detector is used to measure and correct the flicker phenomenon and brightness of the imaging of the near-eye display imaging device. It is conceivable that the fiber optic imaging bundle can have one or more branch output ends, and different branch output ends are connected to different fiber optic imaging detectors.

[0047] Figure 3 This is the third structural diagram of the near-eye display imaging detection system provided in the embodiment of the present application, refer to Figure 3 In some embodiments, the bionic eye fixture is equipped with an electrically controlled slide that matches the bionic eye. The slide is connected to the bionic eye and is configured to rotate the bionic eye during sliding, simulating the up-down and left-right movement of the human eye, further driving the rotation of the input end of the optical fiber imaging bundle. It is contemplated that the slide could be replaced by an electrically controlled slider, an electrically controlled rotating rod, or the like.

[0048] In some embodiments, the near-eye display imaging detection system further includes a fiber optic light guide, the input end of which is connected to an external light source, and the output end of which is located at the retina position of the bionic eyeball body, and the output end rotates as the bionic eyeball body rotates. The electrically controlled slide drives the bionic eyeball body to rotate during the sliding process, and further drives the output end of the fiber optic light guide located at the retina position to rotate. The fiber optic light guide can transmit the light generated by the external light source to the surface of the observed object, that is, the retina position of the bionic eyeball body, to provide a lighting function, so that the virtual image at the retina position is clearer and more visible, and the secondary image transmitted to the fiber optic imaging detector is also clearer and more visible. The external light source emits visible light, which can be an infrared light source, a green light source, an incandescent lamp, etc. The infrared light source is used as an example for explanation below.

[0049] The optical fiber image guide bundle and the optical fiber light guide bundle are the main components of the fiber optic endoscope. The principle of the fiber optic endoscope is mostly used in near-eye display imaging, and in the embodiment of the present application, the input end of the optical fiber image guide bundle is set at the retinal position of the bionic eyeball body, and the virtual image projected by the near-eye display device is transmitted to the optical fiber imaging detector connected to the output end, so as to realize the secondary imaging of the virtual image projected by the near-eye display device, thereby realizing near-eye display imaging detection. Optionally, considering the basic structure of the fiber optic endoscope, an objective lens can be additionally set at the input end of the optical fiber image guide bundle, that is, the retinal position of the bionic eyeball body, and the objective lens is aligned with the retinal position to transmit the virtual image projected by the near-eye display device to the optical fiber imaging detector, rather than directly sensing it by the input end of the optical fiber image guide bundle.

[0050] The near-eye display imaging detection system provided in the embodiment of the present application utilizes optical fibers to transmit the virtual image formed by the near-eye display device at the retinal position of the bionic eyeball to an external optical fiber imaging detector. The use of optical fibers can significantly reduce the overall volume and weight of the system, while transmitting the image information losslessly to the external optical fiber imaging detector, thereby realizing performance detection of the near-eye display device.

[0051] Figure 4 : is a flow chart of the near-eye display imaging detection method provided in an embodiment of the present application, such as Figure 4 As shown, the method includes at least the following steps:

[0052] S401 : Acquire a secondary image of a virtual image projected by a near-eye display device displayed by a fiber optic imaging detector in a near-eye display imaging detection system.

[0053] S402 : Perform performance testing of the near-eye display device based on the secondary image.

[0054] Specifically, the performance of the near-eye display device is tested using the secondary image of the virtual image projected by the near-eye display device displayed by the fiber optic imaging detector in the near-eye display imaging detection system described in the aforementioned system embodiment.

[0055] In some embodiments, S402 specifically includes:

[0056] Determine the actual rotation angle of the bionic eyeball body corresponding to the secondary image, and obtain a reference rotation angle of the bionic eyeball body captured by the near-eye display device;

[0057] An eye tracking function of the near-eye display device is detected based on a first difference between the reference rotation angle and the actual rotation angle.

[0058] Specifically, the bionic eyeball body is rotatably mounted within the bionic eyeball fixture, and the actual rotation angle of the bionic eyeball body is adjustable and known. For example, the bionic eyeball body is rotated by an electrically controlled slide. There is a one-to-one correspondence between the slide's position and the bionic eyeball body's rotation angle. Therefore, the actual rotation angle of the bionic eyeball body can be determined based on the slide's position. The rotation angle of the bionic eyeball body can be defined as the rotation angle relative to the central axis of the bionic eyeball body, with the rotation angle when the bionic eyeball body is looking straight ahead being 0°.

[0059] Near-eye display devices generally have micro cameras or detectors to capture eye movements and implement eye tracking. Figure 3 , the infrared light source connected to the optical fiber guide emits infrared light, which can capture infrared light. At any time T1, the bionic eyeball body rotates. Assuming that the actual rotation angle of the bionic eyeball body is determined to be α1, the direction of the infrared light changes. Based on this, the near-eye display device captures the reference rotation angle of the bionic eyeball body as α2, adjusts the angle of the virtual image it displays and projects it onto the retina position of the bionic eyeball body, and transmits it to the optical fiber imaging detector through the optical fiber guide bundle for secondary imaging, and displays the secondary image at time T2. When the reference rotation angle of the bionic eyeball body is captured as α2, by adjusting the angle of the virtual image it displays, when the bionic eyeball body rotates to a certain angle, the observable virtual image is still clear, and a clear secondary image is displayed at time T2. The near-eye display device can also determine whether the eyeball has rotated and the angle of rotation by taking a picture of the bionic eyeball body.

[0060] The eye tracking capability of the near-eye display device can be tested based on the first difference between the actual rotation angle α1 of the bionic eye and the reference rotation angle α2 captured by the near-eye display device, combined with the display integrity of the secondary image. The display integrity of the secondary image refers to the completeness, clarity, and accuracy of the secondary image when displayed on the fiber-optic imaging detector, including the completeness of the secondary image's content and the clear boundaries during display compared to the virtual image projected by the near-eye display device.

[0061] In some embodiments, detecting an eye tracking function of a near-eye display device specifically includes:

[0062] If the first difference between the reference rotation angle and the actual rotation angle does not exceed the preset range, and the secondary image is displayed completely, it is determined that the eye tracking function of the near-eye display device is qualified; the complete display of the image includes complete content display and clear boundaries.

[0063] Specifically, when the reference rotation angle α2 captured by the near-eye display device is equal to or close to the actual rotation angle α1, that is, the first difference between the reference rotation angle α2 and the actual rotation angle α1 does not exceed the preset range, the secondary image displayed by the fiber optic imaging detector should be a complete picture display, and the complete picture display includes complete content display and clear boundaries, indicating that the eye tracking function of the near-eye display device is qualified.

[0064] Furthermore, the eye tracking function of the near-eye display device can be evaluated based on the first difference between the reference rotation angle α2 and the actual rotation angle α1. It is conceivable that when evaluating the eye tracking function of the near-eye display device, the quantification result of the display integrity of the secondary image can also be combined.

[0065] The near-eye display imaging detection method provided in the embodiment of the present application realizes the detection of the eye tracking function of the near-eye display device by comparing the actual rotation angle of the bionic eyeball body in the near-eye display imaging detection system with the reference rotation angle captured by the near-eye display device.

[0066] In some embodiments, S402 specifically includes:

[0067] Determine the first moment when the bionic eyeball body switches to the target rotation angle;

[0068] determining a second moment when the fiber optic imaging detector displays a secondary image corresponding to the target rotation angle;

[0069] Based on a second difference between the second moment and the first moment, an eye tracking function and a screen switching speed of the near-eye display device are detected.

[0070] Specifically, the bionic eyeball body is controlled to rotate, the rotation angle of the bionic eyeball body is controllable and known, and the bionic eyeball body is controlled to switch the angle at time T0, and switch to the target rotation angle α at time T1. At this time, the near-eye display device can capture the rotation of the bionic eyeball body and switch the display screen, and complete the screen switching at time T2. The screen switching of the near-eye display device will be captured in real time by the fiber optic imaging detector, so the screen switching time of the near-eye display device can be calculated as T2-T1, thereby detecting the eye tracking response speed of the near-eye display device. After the near-eye display device switches the screen, the switched screen is projected to the retinal position of the bionic eyeball body, and then transmitted to the fiber optic imaging detector through the fiber optic image guide bundle for display. The time difference in this process is extremely short and can be ignored when detecting the eye tracking response speed of the near-eye display device.

[0071] In this process, the first moment T1, when the bionic eyeball body switches to the target rotation angle, is determined. Then, the second moment T2, when the fiber optic imaging detector displays a secondary image corresponding to the target rotation angle, is determined. The second difference between the first moment T1 and the second moment T2 is used to measure the eye tracking response speed of the near-eye display device. The smaller the second difference between the first moment T1 and the second moment T2, the faster the eye tracking response speed of the near-eye display device.

[0072] The near-eye display imaging detection method provided in the embodiment of the present application utilizes the second difference between the first moment when the angle switching of the bionic eyeball body is completed and the second moment when the fiber optic imaging detector displays the corresponding secondary image to realize the detection of the eye tracking response speed of the near-eye display device.

[0073] In some embodiments, S402 specifically includes:

[0074] The secondary image is subjected to brightness and / or chromaticity detection, and the image display quality of the near-eye display device is detected based on the detection results.

[0075] Specifically, optical fibers are capable of transmitting high-resolution images and accurately conveying image content. The optical fiber imaging bundle transmits the virtual image projected by the near-eye display device onto the retina of the bionic eye to a fiber-optic imaging detector, where a secondary image of the virtual image is displayed.

[0076] Therefore, the secondary image displayed by the fiber optic imaging detector can be subjected to brightness and / or chromaticity detection, and the brightness and / or chromaticity detection results of the secondary image can be used as the brightness and / or chromaticity detection results of the virtual image projected by the near-eye display device, thereby detecting the image display quality of the near-eye display device. Correspondingly, the fiber optic imaging detector in this case can be an industrial camera, a luminance meter, a colorimeter, or other device that can detect the brightness and / or chromaticity of an image.

[0077] The near-eye display imaging detection method provided in the embodiment of the present application utilizes an optical fiber imaging bundle to transmit the virtual image projected by the near-eye display device on the retinal position of the bionic eyeball body to a fiber optic imaging detector, and displays a secondary image of the virtual image on the fiber optic imaging detector, so that the brightness and / or chromaticity detection results of the secondary image can be used as the brightness and / or chromaticity detection results of the virtual image projected by the near-eye display device, thereby realizing image display quality detection of the near-eye display device.
