[0059] Here, exemplary embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0060] In the field of XR (eXtended Reality) technology, smart glasses are an important carrier of XR technology, and the degree of perfection of their design and functions directly determines the quality of user experience. According to the degree of integration, smart glasses are mainly divided into two categories: split type and integrated type. Split smart glasses effectively solve the power supply problem by separating functional modules such as power supply and drive from the main body of the glasses. However, the resulting wire dragging phenomenon greatly reduces the convenience and comfort of wearing, and cannot meet the high requirements of users for portable wear. In contrast, integrated smart glasses integrate functional modules with the main body of the glasses, successfully avoiding the problem of wire dragging, but the dual-optical machine module on the glasses consumes huge power and requires large-capacity battery support, which increases the weight of the glasses and increases the burden on the wearer's head, thereby seriously affecting the wearer's wearing experience; and smart glasses are inevitably faced with the risk of physical impact such as falling or external force squeezing during daily wear, which causes the position variation of the binocular optical elements of the smart glasses to increase the binocular parallax, resulting in ghosting and dizziness, which seriously interferes with the wearer's visual experience.

[0061] In order to solve the defects of the above-mentioned traditional smart glasses, the present application provides a kind of smart glasses and its parallax correction method, as well as an extended reality device, which not only reduces the power consumption of the smart glasses and reduces the capacity requirement of the glasses battery, thereby reducing the weight of the whole glasses, but also performs an adaptive adjustment structure for binocular parallax variation, ensuring the normal use of the glasses functions, thereby significantly improving the wearer's visual experience.

[0062] The present application embodiment provides a smart glasses, referring to Figure 1 As shown, Figure 1It is a schematic diagram of the optical principle of the smart glasses involved in the first embodiment of the present application. The smart glasses include a waveguide lens 100, an optical machine module 200 and an image detection module 300. The optical machine module 200 includes a light source 10, a light splitting component 20 and a parallax correction adjustment member 30; the light splitting component 20 is configured to split the light source 10 into a first polarized light S and a second polarized light P. The first polarized light S is projected to the left eye area of ​​the waveguide lens 100 through the left-view adjustment mirror of the parallax correction adjustment member 30 to form a left field of view image projected to the image detection module 300, and the second polarized light P is projected to the right eye area of ​​the waveguide lens 100 through the right-view adjustment mirror of the parallax correction adjustment member 30 to form a right field of view image projected to the image detection module 300.

[0063] In this embodiment, the smart glasses provided in this application can be understood as XR glasses, and the XR glasses can be a glasses structure that combines one or more of the following technologies: AR (Augmented Reality) technology, VR (Virtual Reality) technology, and MR (Mixed Reality) technology. Figure 1 The spectroscopic component 20 splits the non-polarized light from the light source 10 into a first polarized light S and a second polarized light P, and projects the first polarized light S and the second polarized light P to the left eye area and the right eye area of ​​the waveguide lens 100 through the left-view adjustment mirror and the right-view adjustment mirror of the parallax correction adjustment member 30, respectively, to form a clear left-view image and a right-view image, thereby achieving the goal of using only one light source 10 to meet the visual display needs of both eyes, avoiding the technical problem of high power consumption of smart glasses caused by the traditional dual-light machine module 200 configuration, that is, the present application significantly reduces the power consumption of smart glasses by splitting the single light source 10 through the spectroscopic component 20, thereby reducing the dependence on large-capacity batteries, further reducing the overall weight of the smart glasses, and thus significantly improving the user's wearing experience.

[0064] It should be noted that the light source 10 includes but is not limited to LED (Light Emitting Diode) lamps, and the incident light of the light source 10 can be understood as non-polarized light from the light source 10; the first polarized light S can be understood as S polarized light, which refers to polarized light in which the electric field vibration direction is perpendicular to the light propagation direction of the incident light; the second polarized light P can be understood as P polarized light, which refers to polarized light in which the electric field vibration direction is the same as the light propagation direction of the incident light.

[0065] The image detection module 300 is configured to determine a field of view matching result based on the left field of view image and the right field of view image, and in response to the field of view matching result being that the left field of view image does not match the right field of view image, trigger the parallax correction adjustment component 30 to adjust the left view adjustment mirror and the right view adjustment mirror until the left field of view image matches the right field of view image.

[0066] In this embodiment, the left field image and the right field image formed by the waveguide lens 100 are coupled to the image detection module 300; at this time, after the image detection module 300 receives the left field image and the right field image coupled by the waveguide lens 100, the image detection module 300 constructs the image detection module 300 based on the middle position and the four corner edge positions of the left field image. Figure 2 (a) shows the left cross template image, and is constructed with the middle position and four corner edge positions of the right field of view image Figure 2 (b) shows the right cross template image; next, determine whether the left cross template image completely overlaps with the right cross template image; if the left cross template image does not completely overlap with the right cross template image, determine that the field of view matching result is that the left field of view image does not match the right field of view image, and immediately respond to the field of view matching result that the left field of view image does not match the right field of view image, trigger the parallax correction adjustment member 30 to adjust its right vision adjustment mirror with the left field of view image as the reference optical image, so that the incident angle of the right exit pupil light formed by the second polarized light P passing through the right vision adjustment mirror and projected onto the right eye area is deflected, until the right field of view image coupled out by the deflected right exit pupil light through the waveguide lens 100 completely overlaps with the left field of view image, thereby realizing binocular parallax correction of the smart glasses, effectively eliminating visual discomfort caused by physical impact or other factors, and significantly improving the wearer's visual experience.

[0067] It should be noted that using the left field image as a reference optical image to drive the parallax correction adjustment member 30 to adjust the right view adjustment mirror is only a feasible implementation of the present application, and the present application does not impose any restrictions on this. Exemplarily, the right field image can also be used as a reference optical image to drive the parallax correction adjustment member 30 to adjust the left view adjustment mirror.

[0068] In another embodiment, the left cross template image and the right cross template image are respectively compared with a preset cross standard template image. If the left / right cross template image does not completely overlap with the cross standard template image, in response to the field of view matching result that the left / right field of view image does not match the cross standard template image, the parallax correction adjustment member 30 is immediately driven to adjust the left / right vision adjustment mirror until the left / right field of view image formed by the first / second polarized light passing through the left / right vision adjustment mirror and incident on the left / right eye area in the waveguide lens 100 completely overlaps with the cross standard template image, thereby realizing binocular parallax correction of the smart glasses, effectively eliminating visual discomfort caused by physical impact or other factors, and significantly improving the wearer's visual experience.

[0069] Further, in some feasible embodiments, the parallax correction adjustment component 30 includes a left pupil distance adjustment module 31 and a right pupil distance adjustment module 32; the left liquid mirror of the left pupil distance adjustment module 31 constitutes a left-view adjustment mirror surface arranged between the left light output surface of the optical machine module 200 and the left eye area, and the right liquid mirror of the right pupil distance adjustment module 32 constitutes a right-view adjustment mirror surface arranged between the right light output surface of the optical machine module 200 and the right eye area.

[0070] In this embodiment, the parallax correction adjustment member 30 integrates a left pupil distance adjustment module 31 and a right pupil distance adjustment module 32, and the left liquid mirror of the left pupil distance adjustment module 31 is placed as a left-view adjustment mirror between the left light-emitting surface of the optical machine module 200 and the left eye area of ​​the waveguide lens 100, and the right liquid mirror of the right pupil distance adjustment module 32 is placed as a right-view adjustment mirror between the right light-emitting surface of the optical machine module 200 and the right eye area of ​​the waveguide lens 100, that is, the incident angle of the left / right exit pupil light projected onto the left / right eye area can be adjusted in real time through the left / right liquid mirror, thereby achieving precise adjustment of the pupil distance, ensuring that the left / right eye can receive the corrected left / right field of view images without parallax, and significantly improving the wearer's visual experience.

[0071] Further, in some other feasible embodiments, referring to Figure 3 , Figure 3 It is a schematic diagram of the pupil distance adjustment member Q100 involved in the embodiment scheme of the present application. The left pupil distance adjustment module 31 and the right pupil distance adjustment module 32 are both the same pupil distance adjustment member Q100, and the left liquid mirror and the right liquid mirror are both the same liquid lens Q10; the pupil distance adjustment member Q100 includes a magnetic metal strip Q20 and a drive unit Q30, and the liquid lens Q10 includes a liquid layer Q12, a top glass Q11 and a bottom cover glass Q13, and a liquid layer Q12 is arranged between the top glass Q11 and the bottom cover glass Q13, and magnetic metal strips Q20 are arranged on both sides of the liquid layer Q12, respectively, and the magnetic metal strip Q20 is fixedly connected to the top glass Q11, and at least one set of drive units Q30 is magnetically attracted on the side of the magnetic metal strip Q20 that is not fixedly connected to the top glass Q11.

The top glass Q11 is fixedly connected to the bottom surface of the top glass Q11, and the magnetic metal strips Q20 arranged on both sides of the liquid layer Q12 are respectively magnetically attracted with at least one driving unit Q30, so that when the field of view matching result is that the left field of view image does not match the right field of view image, or the field of view matching result is that the left / right field of view image does not match the cross standard template image, each driving unit Q30 can be driven at the same time to realize the rotation of the top glass Q11 at any spatial angle, so that the thickness and angle of the liquid lens Q10 are changed, and then the angle change of the left / right exit pupil light can be dynamically changed to realize the correction of randomly varying binocular parallax.

[0073] It should be noted that the interior of the liquid layer Q12 is filled with a transparent liquid with a certain refractive index, and the transparent liquid is wrapped by the outer surface of the liquid layer Q12. A light-transmitting film is attached to the outer surface of the liquid layer Q12, and the shape of the light-transmitting film is convex so that the thickness of the liquid lens Q10 can be changed.

[0074] In a specific embodiment, refer to Figure 3 In the present application, a magnetic metal strip Q20-1 disposed on the right side of the liquid layer Q12 and fixedly connected to the lower surface of the top glass Q11 can magnetically attract a driving unit Q30-1; a magnetic metal strip Q20-2 disposed on the left side of the liquid layer Q12 and fixedly connected to the lower surface of the top glass Q11 can magnetically attract a driving unit Q30-2 and a driving unit Q30-3, or one of the two driving units Q30 magnetically attracted by the magnetic metal strip Q20-2 can be replaced by a fixed structural member. The above is only a feasible implementation method of the present application, and the present application does not impose any limitations hereon.

Specifically, the light splitting component 20 is configured to accurately split the light emitted by the light source 10 into a first polarized light S and a second polarized light P. The first polarized light S and the second polarized light P are respectively projected to the left eye area and the right eye area of ​​the waveguide lens 100 through the left-view adjustment mirror and the right-view adjustment mirror of the parallax correction adjustment member 30, forming a clear left-view image and a right-view image, thereby achieving the use of only one light source 10 to meet the visual display needs of both eyes, avoiding the technical problem of high power consumption of smart glasses caused by the traditional dual-light machine module 200 configuration, that is, the present application significantly reduces the power consumption of smart glasses by splitting the single light source 10 through the light splitting component 20; next, the image detection module 300 receives the left and right field images projected by the waveguide lens 100, and detects the field of view matching result between the left and right field of view images in real time. Once it is detected that the field of view matching result is that the left and right field of view images do not match, that is, there is a parallax phenomenon between the left and right field of view images, the parallax correction adjustment component 30 will be immediately triggered to adjust the left-view adjustment mirror and the right-view adjustment mirror until the left field of view image formed by the left-view adjustment mirror projected onto the left eye area matches the right field of view image formed by the right-view adjustment mirror projected onto the right eye area, thereby effectively eliminating visual discomfort caused by physical impact or other factors, and significantly improving the wearer's visual experience.

[0100] Further, based on the first embodiment of the smart glasses of the present application, a second embodiment of the parallax correction method of the smart glasses of the present application is proposed, referring to Fig.14 , Fig.14 It is a flow chart of the second embodiment of the parallax correction method for smart glasses of the present application.

[0101] The parallax correction method of the smart glasses of the present application is applied to any of the smart glasses mentioned above, and the parallax correction method of the smart glasses of the present application includes the following implementation steps S10 to S30.

[0102] Step S10: Splitting the light source into a first polarized light and a second polarized light by a light splitting component.

[0103] In this embodiment, the spectroscopic component splits the non-polarized light from the light source into a first polarized light and a second polarized light which are perpendicular to each other, that is, the polarization separation of the non-polarized light is achieved through the spectroscopic component, so that the visual display requirements of both eyes can be met by using only one light source, avoiding the technical problem of high power consumption of smart glasses caused by the traditional dual-optical module configuration, significantly reducing the power consumption of smart glasses, thereby reducing the dependence on large-capacity batteries, further reducing the overall weight of the smart glasses, and thus significantly improving the user's wearing experience.

[0104] Step S20: projecting the first polarized light to the left eye area of ​​the waveguide lens through the left-view adjustment mirror of the parallax correction adjustment member to form a left-view image, and projecting the second polarized light to the right eye area of ​​the waveguide lens through the right-view adjustment mirror of the parallax correction adjustment member to form a right-view image;

[0105] In this embodiment, the left-view adjustment mirror of the parallax correction adjustment member can accurately project the first polarized light to the left eye area of ​​the waveguide lens, thereby constructing a clear, three-dimensional left-view image in front of the user's left eye. At the same time, the right-view adjustment mirror of the parallax correction adjustment member is responsible for accurately projecting the second polarized light to the right eye area of ​​the waveguide lens to form a right-view image.

[0106] Step S30: After receiving the left field of view image and the right field of view image projected by the waveguide lens through the image detection module, determining a field of view matching result according to the left field of view image and the right field of view image, and in response to the mismatch between the left field of view image and the right field of view image, triggering the parallax correction adjustment component to adjust the left view adjustment mirror and the right view adjustment mirror until the left field of view image matches the right field of view image.
