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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The following describes in detail the binocular chromatic aberration correction method, device, equipment, and computer-readable storage medium provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0054] According to one embodiment of the present application, a binocular chromatic aberration correction method is provided, and the binocular chromatic aberration correction method is applied to a projection display system. Referring to Figure 1, the projection display system includes a first optical module 11 and a second optical module 12. One of the first optical module 11 and the second optical module 12 corresponds to the right eye (R), and the other corresponds to the left eye (L).

[0055] The binocular chromatic aberration correction method comprises the following steps:

[0056] Controlling the first optical-mechanical module 11 to project a first light beam to form first display image information 131;

[0057] Controlling the second optical engine module 12 to project a second light to form second display image information 132 , and forming a target phase chromatic aberration between the second display image information 132 and the first display image information 131 ;

[0058] The first display screen information 131 and the second display screen information 132 are superimposed to form a fused image through binocular fusion.

[0059] It should be noted that the first display screen information 131 and the second display screen information 132 are generated simultaneously.

[0060] The binocular chromatic aberration correction method provided by the above embodiment can be applied to projection display systems, especially AR display systems. In the entire correction method, the light emitted by one of the illumination light sources in the left and right eye optical machine modules is regulated so that there is a target phase chromatic aberration between the display image information presented in the left eye and the display image information presented in the right eye. Then, binocular fusion is performed in space with the help of the left and right eyes. In this way, the uneven chromaticity of the projected image caused by the eccentric setting of the LED light source itself is solved. The finally formed fused image has the characteristic of low chromatic aberration, which can improve the chromaticity uniformity of the projected image, thereby enhancing the user's visual experience.

[0061] 1 , the binocular chromatic aberration correction method provided in the above embodiment is applied to a projection display system, such as an AR smart glasses. Specifically, the projection display system mainly comprises a first optical engine module 11 and a second optical engine module 12.

[0062] In one example, please continue to refer to Figure 1, the first optical module 11 is designed to correspond to the right eye (R), which is the right eye (R) optical module; and the second optical module 12 is designed to correspond to the left eye (L), which is the left eye (L) optical module, and the two are placed symmetrically.

[0063] The first optical engine module 11, corresponding to the right eye, can emit a first light beam. This first light beam is projected and formed into a first display image 131 in the user's right eye (R). The second optical engine module 12, corresponding to the left eye, can emit a second light beam. This second light beam is projected and formed into a second display image 132 in the user's left eye (L). Based on this, the second light beam can be adjusted so that the second display image 132 formed by the second light beam is different from the first display image 131, forming a certain target phase chromatic difference between the two.

[0064] Of course, the second light may be kept unchanged while the first light is adjusted, and this is not limited in the embodiment of the present application.

[0065] The first display picture information 131 and the second display picture information 132 formed can correct the chromaticity unevenness existing in a single eye after binocular fusion of the left and right eyes, thereby achieving the purpose of binocular chromatic aberration correction. The fused image 13 after binocular fusion can be shown in Figure 1.

[0066] It should be noted that projection display systems typically include an illumination light source that emits light. When the illumination light source is a multi-color light source, such as a four-in-one light source, the light source typically includes two green light units (G), one red light unit (R), and one blue light unit (B), arranged diagonally. For example, the red light unit is located in the upper left corner, while the blue light unit is located in the lower right corner, as shown in Figure 1. Consequently, the display image information projected by each eye inevitably results in uneven color, potentially resulting in a reddish tint in the upper left corner and a bluish tint in the lower right corner.

[0067] The solution provided in the embodiments of the present application adjusts the display image information presented in one eye and then superimposes it with the display image information presented in the other eye. At this time, for example, red and blue colors can be blended, which can correct the chromatic unevenness existing in one eye, thereby achieving the purpose of binocular chromatic aberration correction.

[0068] It should be noted that both the first display image information 131 and the second display image information 132 shown in Figure 1 have uneven projected image color, which is represented by grayscale in the figure. By adopting the binocular chromatic aberration correction method provided by the above embodiment of the present application, the color uniformity of the final fused image 13 can be improved.

[0069] In some examples of the present application, referring to FIG. 1 , the target phase chromatic difference between the second display screen information 132 and the first display screen information 131 is 180°, so that the second display screen information 132 is opposite to the first display screen information 131 .

[0070] According to the above example, referring to FIG1 , the first optical engine module 11 corresponding to the right eye (R) remains unchanged. By rotating the illumination source in the second optical engine module 12 corresponding to the left eye (L) by 180 degrees, for example, the red light R and blue light B in the illumination source are distributed as follows: red light R in the lower right and blue light B in the upper left. This design enables the second display image information 132 projected by the second optical engine module 12 for the left eye to appear bluish in the upper left and reddish in the lower right, which is exactly the opposite of the first display image information 131 seen by the right eye. Ultimately, the first display image information 131 and the second display image information 132 are binocularly fused to correct for the chromatic aberration that exists in a single eye, thereby achieving the purpose of binocular chromatic aberration correction.

[0071] In some examples of the present application, referring to FIG1 , the first light and the second light both include visible light of multiple different wavelength bands, thereby forming a color projection image.

[0072] In some examples of the present application, the first optical-mechanical module 11 includes a first illumination light source 111, the second optical-mechanical module 12 includes a second illumination light source 121, and the first illumination light source 111 is the same as the second illumination light source 121. The binocular chromatic aberration correction method further includes:

[0073] Before forming the second display image information, the second illumination light source 121 is controlled to rotate 180° so as to form a 180° phase chromatic difference between the second light projected by the second illumination light source 121 and the first light projected by the first illumination light source 111 .

[0074] According to the above example, the second light can be adjusted by, for example, controlling the rotation of the second illumination light source 121. This method of adjusting the second light is relatively simple.

[0075] For example, a driving member may be introduced, and the rotation of the second illumination light source 121 may be automatically controlled by the driving member, which makes the entire correction method easier to implement.

[0076] In some examples of the present application, referring to FIG1 , the first illumination light source 111 and the second illumination light source 121 each include a green light unit G, a red light unit R, and a blue light unit B. Two green light units B are provided and arranged diagonally, while the red light unit R and the blue light unit G are also arranged diagonally. When the first display image information 131 and the second display image information 132 are superimposed, the red and blue lights at the diagonal positions are superimposed and merged.

[0077] According to the above example, both the first illumination light source 111 and the second illumination light source 121 are four-in-one light sources including RGB three-color light. The optical solution provided by the embodiment of the present application does not require any improvement to the illumination light source itself.

[0078] In some examples of the present application, referring to FIG1 , the projection display system further includes a first light guide device 115 and a second light guide device 125. The first light guide device 115 is provided with a first coupling inlet 114 and a first coupling outlet. The first light enters the first light guide device 115 through the first coupling inlet 114, and is totally reflected in the first light guide device 115 and propagates to the first coupling outlet for coupling out to form the first display image information 131. The second light guide device 125 is provided with a second coupling inlet (obscured and therefore not shown in FIG1 ) and a second coupling outlet. The second light enters the second light guide device 125 through the second coupling inlet, and is totally reflected in the second light guide device 125 and propagates to the second coupling outlet for coupling out to form the second display image information 132.

[0079] The first light guide device 115 and the second light guide device 125 are, for example, diffraction waveguides, which are provided with a coupling inlet for coupling in light and a coupling outlet for coupling out light.

[0080] For example, the first light guide device 115 and the second light guide device 125 can be respectively provided in two frames of the AR glasses.

[0081] According to the above example, the user's right eye can see the first display screen information 131 from the first coupling outlet on the first light guide device 115, and the user's left eye can see the second display screen information 132 from the second coupling outlet on the second light guide device 125. Finally, the first display screen information 131 and the second display screen information 132 are binocularly fused by the left eye to form a fused image 13. The fused image 13 has the characteristic of good chromaticity uniformity, so that the chromaticity unevenness existing in a single eye can be corrected, thereby achieving the purpose of binocular chromatic aberration correction.

[0082] For the projection display system used in this application, the first optical engine module 11 includes, in addition to the aforementioned first illumination light source 111 (e.g., a four-in-one light source for emitting RGB light), a collimator assembly, a fly-eye assembly, and a relay assembly. It may also include, for example, a first PBS prism system 112 and a first projection lens. The chip in the first projection lens uses an LCOS display chip. Based on this, the propagation path of the first light is as follows:

[0083] The first illumination light source 111 emits a first light ray, which is an RGB light ray. The first light ray passes through the collimator assembly, the fly-eye assembly, and the relay assembly in sequence and is incident on the first PBS prism system 112. The first PBS prism system 112 reflects the first PBS prism system 112 and then is reflected onto the LCOS display chip. The LCOS display chip can modulate the incident illumination light and carry the display image information. The light then passes through the first PBS prism system 112 and the first projection lens and is incident on the first coupling port 114 of the first light guide device 115. The user's right eye can then see the first display image information 131 through the first coupling port of the first light guide device 115.

[0084] Similarly, in addition to the aforementioned second illumination light source 121 (for example, a four-in-one light source for emitting RGB light), the second optical engine module 12 may also include a collimating component, a compound eye component and a relay component. It may also include, for example, a second PBS prism system 122 and a second projection lens. The chip in the second projection lens also uses an LCOS display chip.

[0085] It should be noted that the embodiment of the present application does not improve the optical structure of the projection optical system itself, and mainly focuses on controlling the light emitted by one of the illumination light sources.

[0086] By measuring the first optical machine module 11 and the second optical machine module 12, a 385*385 display screen was projected at a distance of 1100mm from the optical machine exit pupil, and the brightness values ​​and x, y color coordinates of the 9 center points in the display screen information were tested using a CL2000 color illuminance meter. The recorded data is shown in Figure 2.

[0087] Definition: ANSI 9-point Brightness Uniformity = Min (L1 ... L9) / Max (L1 ... L9).

[0088] x color coordinate chromaticity deviation △x=Max(x1…..x9)-Min(x1…..x9);

[0089] Y color coordinate chromaticity deviation △y=Max(y1…..y9)-Min(y1…..y9);

[0090] The larger the ANSI 9 point Brightness Uniformity, the better. The smaller the color coordinate chromaticity deviation △x and △y, the better.

[0091] Referring to FIG2 , the optical performance of the second optical-mechanical module 12 corresponding to the left eye (L) is as follows:

[0092] ANSI 9 point Brightness Uniformity=82%;

[0093] x color coordinate chromaticity deviation △x=0.02400;

[0094] The y color coordinate chromaticity deviation △y=0.01861.

[0095] The optical performance of the first optical-mechanical module 11 corresponding to the right eye (R) is as follows:

[0096] ANSI 9 point Brightness Uniformity=85%;

[0097] x color coordinate chromaticity deviation △x=0.03010;

[0098] The y color coordinate chromaticity deviation △y=0.02050.

[0099] The optical performance of the first optical-mechanical module 11 and the second optical-mechanical module 12 after binocular fusion is as follows:

[0100] ANSI 9 point Brightness Uniformity=88%;

[0101] x color coordinate chromaticity deviation △x=0.00570;

[0102] The y color coordinate chromaticity deviation △y=0.00980.

[0103] The above measurements show that when the second optical engine module 12 for the left eye and the first optical engine module 11 for the right eye are used independently, ANSI 9-point uniformity is low and the x- and y-color coordinate deviations are large. However, by binocularly fusing the second optical engine module 12 for the left eye and the first optical engine module 11 for the right eye, ANSI 9-point uniformity can be significantly improved and the chromaticity deviations of the x- and y-color coordinates can be reduced.

[0104] According to another embodiment of the present application, a binocular chromatic aberration correction device is provided.

[0105] The binocular chromatic aberration correction device is arranged in a projection display system. Referring to FIG1 , the projection display system includes a first optical module 11 and a second optical module 12. One of the first optical module 11 and the second optical module 12 corresponds to the right eye (R), and the other corresponds to the left eye (L).

[0112] According to the above-mentioned embodiment of the present application, a binocular chromatic aberration correction device that can be applied to a projection display system is provided. By controlling the light emitted by an illumination light source in the left and right eye optical machine modules, a target phase chromatic aberration is created between the display picture information presented in the left eye and the display picture information presented in the right eye. Then, binocular fusion is performed in space with the help of the left and right eyes. In this way, the uneven chromaticity of the projected picture caused by the eccentric setting of the LED light source itself is solved. The finally formed fused picture has the characteristic of low chromatic aberration, which can improve the chromaticity uniformity of the projected picture, thereby enhancing the user's visual experience.
