For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.

"upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

In recent years, head-mounted display technology has been actively developed, and is widely used in the fields of enterprise users (To B) and end users (To C), including Augmented Reality (AR) display technology and virtual reality (VR display technology, wherein augmented reality (Augmented Reality, abbreviated as AR) is a virtual-real combined technology, so-called "virtual" is a virtual image, an image displayed by a micro-display and amplified and transmitted To the human eye through an optical element, so-called "real" is a real reality environment, and augmented reality technology is a technology of superposing a virtual image and a real world.

The virtual reality display technology is an opaque display technology and provides an immersive visual experience for people.

The display device is generally a binocular display module, and the left eye display module and the right eye display module display the same or parallax images to enable the human eyes to form left eye images and right eye images into stereoscopic images. Because of the characteristics of human eyes, parameters of binocular imaging, such as vertical divergence of an aiming axis of left and right eyes, relative image inclination, imaging distance accuracy and the like, need to be measured and controlled.

Because the binocular imaging detection method and device are applicable to rapid and automatic detection devices, the binocular camera is multipurpose. As shown in fig. 1, the binocular camera for implementing binocular imaging detection needs two cameras with consistent parameters and calibration completion, the distance between optical axes of the cameras is equal to the inter-pupil distance (IPD), and the problems of large volume, high cost (two sets of cameras are needed), high image processing difficulty and the like exist.

Fig. 2 shows a schematic diagram of an exemplary binocular imaging detection apparatus 100 provided by an embodiment of the present disclosure.

As shown in fig. 2, the binocular imaging apparatus 100 of the binocular display module may include a first optical component 102, a second optical component 104, and an imaging component 106. In some embodiments, the apparatus 100 may further comprise a control unit 108. The components may be secured together by structural members to form a unitary device. Optionally, the binocular display module is a virtual reality device or an augmented reality device. The positional relationship of the first optical assembly 102, the second optical assembly 104, the imaging assembly 106, and the control unit 108 is shown in the figure, wherein:

The first optical assembly 102 is configured to: the first light of the first display module 202 of the binocular display module 200 is transmitted to the imaging assembly 106 through a first light path 1022.

The second optical assembly 104 is configured to: the second light of the second display module 204 of the binocular display module 200 is transmitted to the imaging assembly 106 through a second light path 1042.

The imaging assembly 106 is configured to: and acquiring the first light ray and the second light ray, and imaging according to the first light ray and the second light ray, wherein the imaged images are used for binocular imaging detection.

The control unit 108 is configured to: and displaying the images of the first light ray and the second light ray formed by the imaging component, and/or calculating the combination image parameters of the binocular display module.

Optionally, when the control unit 108 needs to display the images of the first light and the second light imaged by the imaging assembly, the control unit 108 may further include a display screen, in addition to computing and processing capabilities, for displaying the images of the first light and the second light imaged by the imaging assembly, so that a staff performing binocular imaging detection may perform parameter adjustment based on the displayed images. As an alternative embodiment, the control unit 108 may be independent of the binocular imaging apparatus 100 including the first optical assembly 102, the second optical assembly 104, and the imaging assembly 106, for example, the control unit 108 may be implemented by a computer or similar computer device.

Optionally, the image combining parameters may further include monocular performance parameters and binocular performance parameters. Monocular performance parameters may include Eye point distance (EYE RELIEF), eye Box (Eye Box) range, field of view (FOV), distortion (display), brightness, contrast, chromaticity, resolution, virtual image distance, transmittance, and the like. The binocular performance parameters may include uniformity of monocular parameters (field angle differences, distortion differences, resolution differences, brightness differences, etc.), binocular image characteristics (Binocular Properties) (e.g., horizontal convergence angle, vertical divergence angle (VERTICAL DIVERGENCE), relative image tilt angle, image distance accuracy, etc.).

In an actual test, the first display module 202 and the second display module 204 may be turned on sequentially to emit the first light and the second light at different times, so that the control unit 108 may calculate monocular performance parameters of the first display module 202 and the second display module 204 according to the optical data collected at different times, and may calculate binocular performance parameters according to the monocular performance parameters. In other scenarios, the first display module 202 and the second display module 204 may be turned on simultaneously to emit the first light and the second light, and the imaging component 106 converges the light, so that the control unit 108 may calculate the binocular performance parameter based on the collected converged light.

After the image combination parameter is obtained by calculation, the spatial postures of the first display module 202 and the second display module 204 can be adjusted according to the image combination parameter, then the test is performed again, and the process is repeated until the parameter meets the requirement. In other scenarios, the display parameters of the first display module 202 and the second display module 204 may be adjusted (e.g., optical compensation, etc.) according to the calculated image combination parameters.

Fig. 3A shows a schematic structural diagram of an exemplary binocular imaging detection apparatus 100 provided by an embodiment of the present disclosure.

As shown in fig. 3A, in some embodiments, the imaging assembly 106 may further include a beam splitting element 1062 and an imaging element 1064, where the beam splitting element 1062 may be a beam splitting prism or a beam splitting flat sheet, and the imaging element 1064 may be a camera or lens. The light-splitting element 1062 is disposed at a boundary between the first optical path 1022 and the second optical path 1042, and the imaging element 1064 is disposed on the light-emitting side of the light-splitting element 1062. Like this, combine beam combining and then transmit imaging element 1064 with first light and second light through beam splitting element 1062 for imaging element 1064 can just set up one and just can accomplish the collection to the optical data of binocular display module assembly, simple structure, cost are lower.

In some embodiments, as shown in fig. 3A, the first optical component 102 (e.g., the first mirror 1024) is disposed on a first side of the beam-splitting element 1062, the second optical component 104 (e.g., the second mirror 1044 and the third mirror 1046) is disposed on a second side of the beam-splitting element 1062, and the imaging element 1064 is disposed on a third side of the beam-splitting element 1062. By means of the surrounding type structural design, the structure can be more compact.

In some embodiments, as shown in fig. 3A, the first optical assembly 102 includes a first mirror 1024, the first mirror 1024 is disposed on the first optical path 1022, and a reflective surface of the first mirror 1024 is configured to reflect the first light to the light splitting surface 10622 of the light splitting element 1062.

In some embodiments, as shown in fig. 3A, the second optical component 104 includes a second mirror 1044 and a third mirror 1046, where the reflective surfaces of the second mirror 1044 and the third mirror 1046 are opposite and parallel, the second mirror 1044 and the third mirror 1046 are disposed on the second optical path 1042, and the reflective surfaces of the second mirror 1044 and the third mirror 1046 are configured to transmit the second light to the splitting surface 10622 of the splitting element 1062 by reflection.

As shown in fig. 3A, the first reflecting mirror 1024 receives the first light emitted from the first display module 202 of the binocular display module 200, and reflects the first light to the beam splitting element 1062, and the first light enters the imaging element 1064 after being reflected by the beam splitting element 1062;

The third reflecting mirror 1046 receives the second light beam emitted from the second display module 204 of the binocular display module 200, and the second reflecting mirror 1044 reflects the second light beam to the light splitting element 1062 again, and the second light beam enters the imaging element 1064 after passing through the light splitting element 1062.

The relative angle relationship between the light splitting surfaces of the first mirror 1024, the second mirror 1044, the third mirror 1046 and the light splitting element 1062 needs to ensure that the included angle between the central view field light rays of the first display module 202 and the second display module 204 entering the imaging element 1064 is equal to the requirement of binocular image, so that the imaging element 1064 receives the left eye image and the right eye image displayed by the first display module 202 and the second display module 204 of the binocular display module, and the parameters of binocular image can be detected by the relative positions of the left eye image and the right eye image. Alternatively, the first display module 202 and the second display module 204 may display patterns of different colors or lines.

As a specific example: when the binocular imaging distance is infinity, the included angle between the left and right central view field light rays entering the imaging element 1064 is required to be 0 °, and the first mirror 1024, the second mirror 1044, the third mirror 1046, and the light splitting element 1062 may adopt the following angular relationships: the reflecting surface of the first reflecting mirror 1024 is parallel to the light splitting surface of the light splitting element 1062, and the reflecting surface of the second reflecting mirror 1044 is parallel to the reflecting surface of the third reflecting mirror 1046.

In practical implementation, because of the existence of tolerance, the relative relationship of the optical elements may deviate slightly from the specific example, and the relative relationship may be adjusted according to the actual precision requirement.

When the spectroscopic element 1062 is a spectroscopic prism, a part of the light reflected by the first mirror 1024 is transmitted, reaches the surface of the spectroscopic prism far from the first mirror 1024, and a part of the light reflected by the second mirror 1044 is reflected, reaches the surface of the spectroscopic prism far from the first mirror 1024, and such light is reflected again to form stray light.

Thus, in some embodiments, as shown in fig. 3B, to eliminate stray light, the first optical component 102 is disposed on a first side of the light-splitting element 1062 facing the light-splitting surface 10622, the second optical component 104 is disposed on a second side of the light-splitting element 1062 facing the light-splitting surface 10622, the imaging element 1064 is disposed on a third side of the light-splitting element 1062 facing the light-splitting surface 10622, and a fourth side of the light-splitting element 1062 facing the light-splitting surface 10622 (a surface away from the first mirror 1024) is provided with an extinction layer 10624 (which may also be referred to as a light-absorbing layer). Thus, stray light can be better eliminated by performing an extinction treatment (such as a paint) on the fourth side of the spectroscopic element 1062 by using the extinction layer 10624.

When the exit pupil size of the binocular display module is large, such as an optical waveguide display module, the beam size is large, and may reach a non-optical surface of the optical element (such as a side wall of a reflector), causing stray light.

Thus, in some embodiments, as shown in fig. 3C, the first optical assembly 102 includes a first diaphragm 1026, the first diaphragm 1026 being disposed between the first optical assembly 102 and the first display module 202, configured to: the beam size of the first light directed to the first optical component 102 is adjusted (e.g., the beam size is limited).

In some embodiments, as shown in fig. 3C, the second optical component 104 includes a second diaphragm 1048, the second diaphragm 1048 being disposed between the second optical component 104 and the second display module 204 and configured to: the beam size of the second light rays directed to the second optical assembly 104 is adjusted (e.g., the beam size is limited).

Fig. 4A shows a schematic structural diagram of another exemplary binocular imaging detection apparatus 300 provided by an embodiment of the present disclosure.

As an alternative embodiment, as shown in fig. 4A, the first optical component 102 of the binocular imaging detection apparatus 300 includes a right angle prism 302, the right angle prism 302 is disposed on the first optical path 1022, and the reflecting surface 3022 of the right angle prism 302 is configured to reflect the first light beam to the light splitting surface 10622 of the light splitting element 1062.

In some embodiments, as shown in fig. 4A, the second optical component 104 of the binocular image detection apparatus 300 includes an rhomb prism 304, the rhomb prism 304 is disposed on the second optical path 1042, and the reflection surfaces 3042, 3044 of the rhomb prism 304 are configured to transmit the second light to the beam splitting surface 10622 of the beam splitting element 1062 through reflection.

In this way, because the equivalent air layer thickness is the glass plate thickness or the refractive index of the prism material after the prism is unfolded, by replacing the first mirror 1024 with the right-angle prism 302 and replacing the second mirror 1044 and the third mirror 1046 with the rhombic prism 304, the equivalent air layer thickness of the light reaching the imaging element 1064 can be shortened, the imaging element 1064 can be more close to the exit pupil or the eye box position of the display module to be tested, the requirement on the lens entrance pupil position in the 1064 is reduced, and the prism can prevent the reflective surface from being stained.

Alternatively, the reflective surfaces 3022, 3042, 3044 may be realized by the principle of total reflection, or may be realized by plating a reflective film on the respective surfaces.

In some embodiments, as shown in fig. 4B, for a binocular display module having a smaller exit pupil size, the first optical assembly 102 includes a first exit pupil expansion element 306, the first exit pupil expansion element 306 disposed between the first optical assembly 102 and the first display module 202 configured to: the beam size of the first light directed to the first optical component 102 is adjusted.

The first exit pupil expansion element 306 and the second exit pupil expansion element 308 may be to copy the aperture of the optical system a plurality of times in the horizontal and vertical directions to expand the angle of view that the optical system can accommodate, thereby achieving an enlargement of the beam size. It will be appreciated that the first exit pupil expansion element 306 and the second exit pupil expansion element 308 can also be provided in the apparatus 100 shown in fig. 3A-3C, and are not limited to being provided in the apparatus 300 of the present embodiment.

In some embodiments, as shown in fig. 4A and 4B, a first diaphragm 1026 and a second diaphragm 1048 may also be provided in the device 300, thereby achieving a similar function in the device 100. It will be appreciated that the first diaphragm 1026 and the second diaphragm 1048 are mainly used to avoid stray light generated by the light entering the first optical assembly 102 and the second optical assembly 104, and the first exit pupil expansion element 306 and the second exit pupil expansion element 308 are mainly used to enlarge the beam size, so that the first diaphragm 1026 and the second diaphragm 1048 may be disposed near the first mirror 1024, the second mirror 1044, the third mirror 1046, or the rectangular prism 302, the rhomb prism 304, and the first exit pupil expansion element 306 and the second exit pupil expansion element 308 may be disposed near the first display module 202 and the second display module 204.

As an alternative embodiment, as shown in fig. 5A, taking the first exit pupil expansion element 306 as an example (the second exit pupil expansion element 308 may have a similar structure), the first exit pupil expansion element 306 may include an in-coupling area 3062 and an out-coupling area 3064, the in-coupling area 3062 is used to receive the light emitted by the display module, and the out-coupling area 3064 may emit the amplified light to the first mirror 1024, the rectangular prism 302 or the first diaphragm 1026. Optionally, as shown in fig. 5B, the first exit pupil expansion element 306 may further comprise a turning region 3066, and the relative position of the coupling-in region 3062 and the coupling-out region 3064 may be adjusted more flexibly by providing the turning region 3066, so that light transmission is better achieved.

In some embodiments, the first exit pupil expansion element 306 and the second exit pupil expansion element 308 are the same exit pupil expansion element 310, and the exit pupil expansion element 310 may comprise only one region having both coupling-in and coupling-out functions, or the exit pupil expansion elements 310 may share the same coupling-out region. As shown in fig. 5C, the exit pupil expansion element 310 comprises a first coupling-in area 3102A, a second coupling-in area 3102B and a coupling-out area 3104, the first coupling-in area 3102A being arranged between the first optical assembly 102 and the first display module 202, the second coupling-in area 3102B being arranged between the second optical assembly 104 and the second display module 204, the coupling-out area 3104 being arranged on the light entrance side of the first optical assembly 102 and the second optical assembly 104, whereby the structure is further simplified by sharing the exit pupil expansion element. As shown in fig. 5C, the light emitted from one eye of the binocular display module is coupled in through the first coupling-in region 3102A, coupled out through the coupling-out region of the exit pupil expansion element 310, and enters the subsequent optical path; light rays exiting from the other eye of the binocular display module are coupled in through the second coupling-in region 3102B, coupled out through the coupling-out region of the exit pupil expansion element 310, and enter the subsequent optical path. Optionally, as shown in fig. 5D, the exit pupil expansion element 310 may further comprise a first turning region 3106A and a second turning region 3106B.

Fig. 6A shows a schematic structural diagram of yet another exemplary binocular imaging detection apparatus 400 provided by an embodiment of the present disclosure.

Referring to fig. 5A and 5B, the first waveguide element 402 and the second waveguide element 404 may also include a coupling-in area and a coupling-out area, where the coupling-in areas of the two are aligned with the exit pupil positions of the first display module (monocular module) 202 and the second display module (monocular module) 204 of the binocular display module, respectively, the coupling-out areas of the first waveguide element 402 and the second waveguide element 404 overlap and are aligned with the imaging element 1064, and the light rays emitted from the left and right monocular modules are transmitted through the first waveguide element 402 and the second waveguide element 404, and after being coupled out in the coupling-out areas, the directions are unchanged, and are combined into one beam of light rays to enter the imaging element 1064, so that the parameters of binocular imaging can be detected through the relative positions of the images. Alternatively, the first display module 202 and the second display module 204 may display patterns of different colors or lines.

In some embodiments, as shown in fig. 6B, the first waveguide element 402 and the second waveguide element 404 are the same waveguide element, the waveguide element 406 may have a structure similar to that shown in fig. 5C or fig. 5D, the two coupling-in areas are aligned with the exit pupil of the left and right monocular modules of the binocular display module respectively, the coupling-out areas are aligned with the imaging element 1064, the light rays emitted from the left and right monocular modules are transmitted through the waveguide element 406, and after being coupled out from the coupling-out areas, the directions of the light rays are unchanged, and the light rays are combined into a bundle of light rays to enter the imaging element 1064, so that the parameters of binocular image combination can be detected through the relative positions of the images. Alternatively, the left and right display modules may display patterns of different colors or lines.

In some embodiments, as shown in fig. 6C, the apparatus 400 may further include a third diaphragm 408, where the third diaphragm 408 is disposed between the waveguide 406 and the imaging element 1064, and is configured to adjust a beam size (e.g., limit a beam size) of the light coupled out of the waveguide 406 toward the imaging element 1064, thereby eliminating stray light.

In order for the components of the binocular imaging detection apparatus (e.g., apparatus 100, 300, 400) to achieve rapid assembly and to adapt to the requirements of binocular display mode combined image distance (angle within the central field of view ray level), in some embodiments, the binocular imaging detection apparatus further includes a first adjustment assembly coupled to the first optical assembly 102 and configured to adjust the pose (e.g., spatial position or spatial angle) of the first optical assembly 102.
