[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0049] At present, the assembly of AR glasses is generally divided into two steps: first the optical machine assembly, and then the whole machine assembly. However, since AR glasses usually need to be calibrated with active alignment equipment to meet the optical performance requirements, a set of active alignment equipment is needed to calibrate the optical machine during the optical machine assembly to solve problems such as dark edges or pixels of the optical machine. When assembling the whole machine, another set of active alignment equipment is needed to calibrate the whole machine to solve the problem of image coincidence between the optical machine and the waveguide. Therefore, two sets of active calibration equipment are needed to calibrate AR glasses separately during assembly, which makes the assembly process of AR glasses more complicated and costly.

[0050] Based on this, the present invention proposes a frame structure for AR glasses, aiming to optimize the problem of complex and high cost assembly process of existing AR glasses. Figures 1 to 7 A schematic diagram of the AR glasses and the calibration method thereof provided by the present invention.

[0051] See also Figures 1 to 3 In one embodiment of the present invention, the frame structure 100 includes a frame body 1 and two optical-mechanical mounting parts 2. The frame body 1 has an inner side and an outer side in the thickness direction thereof. The inner side or the outer side of the frame body 1 has two mounting areas for correspondingly mounting two waveguides 5. Each of the mounting areas is provided with a mounting hole 11 that passes through the inner side and the outer side of the frame body 1. The two optical-mechanical mounting parts 2 are provided corresponding to the two mounting areas and are integrally provided on the frame body 1. An optical channel 211 is formed in each of the optical-mechanical mounting parts 2. The optical channel 211 is used for mounting an imaging module 41. One end of the optical channel is connected to the mounting area so that the light of the imaging module 41 can be incident on the waveguide 5. The other end is provided through the free end of the optical-mechanical mounting part 2. The free end of the optical-mechanical mounting part 2 is used for mounting an illumination module 42.

[0052] It should be noted that the inner side of the frame body 1 refers to the side of the frame body 1 facing the user's eyes, and the outer side of the frame body 1 refers to the side of the frame body 1 away from the human eye. The waveguide 5 is a key optical component for transmitting digital images from a microdisplay to the user's eyes, and is used to combine the virtual image from the optical machine 4 with the real-world scene seen by the user. Its working principle is to guide light through a transparent medium (usually glass or plastic) by total internal reflection, thereby achieving effective transmission of image information. The optical machine 4 of the AR glasses usually refers to an optical engine or display module, which is a key component responsible for generating and projecting images into the user's field of view, including an imaging module 41 and an illumination module 42.

[0053] The technical solution of the present invention is to set the frame body 1 to form the two installation areas, to install the waveguide 5 on the frame body 1 by setting the installation holes 11 in each of the installation areas, and to install the imaging module 41 and the lighting module 42 by setting the optical machine installation part 2. At the same time, the frame body 1 and the optical machine installation part 2 are integrally set to assemble the waveguide 5 and the optical machine 4 together in the frame structure 100, so as to calibrate the waveguide 5 and the optical machine 4 at the same time, so as to optimize the step-by-step calibration into synchronous calibration, so that the AR glasses can be calibrated by using a set of active alignment equipment, which can not only save the assembly process of the frame structure 100 and save time, but also reduce the assembly cost.

[0054] For further information, see Figures 2 to 4 , the optical-mechanical mounting portion 2 is arranged on the inner side of the frame body 1, the two mounting areas are arranged on the outer side of the frame body 1, and one end of the optical channel is arranged through the outer side of the frame body 1. In this way, the mounting area and the optical-mechanical mounting portion 2 are respectively arranged on both sides of the frame body 1, so as to make full use of the space of the frame body 1, which is convenient for installation on the waveguide 5, and for installation of the imaging module 41 and the lighting module 42. The optical-mechanical mounting portion 2 and the temples of the frame structure 100 can also be arranged on the same side, which is beneficial to improving the appearance of the mirror body. Of course, in other embodiments, the mounting area and the optical-mechanical mounting portion 2 can also be arranged on the frame body 1 and at the same time on the outer side or the inner side of the frame body 1, and the present invention is not limited to this.

[0055] In one embodiment of the present invention, see Figures 3 to 5The outer side of the frame body 1 has two grooves 12 to form the two installation areas, and the two grooves 12 are corresponding to the two waveguides 5 for installation. Thus, by setting the grooves 12, on the one hand, the position of the waveguide 5 can be located on the mirror body so that the waveguide 5 can be quickly installed on the frame body 1, and on the other hand, the thickness of the frame body 1 can be utilized so that the waveguide 5 can be as flush as possible with the outer side of the frame body 1, thereby helping to improve the appearance of the AR glasses.

[0056] Please note that Figure 4 The outer peripheral wall of the waveguide 5 is retracted to form a positioning step surface facing the frame body 1 . Thus, by setting the positioning step surface to cooperate with the groove 12 , the waveguide 5 can be positioned on the frame body 1 .

[0057] Furthermore, in one embodiment, a positioning surface is formed on the side wall of the groove 12, and the positioning surface is used to adapt to the side surface of the waveguide 5 to limit the movement of the waveguide 5 on the plane where the outer side of the frame body 1 is located. In this way, by setting the positioning surface, the waveguide 5 is confined in the groove 12 to prevent the waveguide 5 from moving outside the frame body 1, so that the groove 12 can pre-position the waveguide 5, thereby helping to fix the waveguide 5 on the frame body 1.

[0058] In one embodiment of the present invention, see Figure 4 and Figure 5 , a glue dispensing groove 13 is provided on the side wall of the groove 12, so that glue can flow into the groove 12 through the glue dispensing groove 13 to fix the waveguide 5 on the frame body 1. In this way, the glue dispensing groove 13 is provided to facilitate the assembly personnel to perform glue dispensing. Furthermore, a plurality of glue dispensing grooves 13 are provided, and a plurality of the glue dispensing grooves 13 are provided at intervals along the circumference of the groove 12. In this way, a plurality of the glue dispensing grooves 13 are provided to dispense glue to different positions of the waveguide 5 along its circumference, so that the glue can be distributed along the circumference of the groove 12, avoiding problems such as local glue leakage, thereby helping to strengthen the connection between the waveguide 5 and the frame body 1. Of course, in other embodiments, the waveguide 5 can also be fixed to the frame body 1 by screws, etc., as long as the waveguide 5 can be fixed to the frame body 1, the present invention is not limited to this.

[0059] It should be noted that the above two related technical features: "the side wall of the groove 12 is formed with a positioning surface" and "the side wall of the groove 12 is provided with a glue point groove 13" can be set either one or at the same time. Obviously, setting them at the same time will have a better effect.

[0060] In one embodiment of the present invention, see Figure 3 , Figure 4 and Figure 6 The optical machine mounting portion 2 includes a lens barrel 21 and an optical frame 22. One end of the lens barrel 21 is arranged on the inner side of the frame body 1. The optical channel 211 includes the inner cavity of the lens barrel 21. The optical frame 22 is arranged at the other end of the lens barrel 21 for installation of the illumination module 42. Thus, by setting the lens barrel 21, the optical channel 211 is formed so as to install the imaging module 41, so that the light emitted by the illumination module 42 can be emitted into the waveguide 5 after passing through the imaging module 41, and by setting the optical frame 22, the illumination module 42 is installed so as to emit light to the imaging module 41.

[0061] It should be noted that the lens barrel 21 may have a variety of shapes, such as cylindrical or prismatic, as long as it can form the optical channel 211 , and this application does not impose any limitation on this.

[0062] For further information, see Figure 3 The optical frame 22 includes an optical frame 221 and two fixing plates 222. The optical frame 221 has two first mounting sides that are arranged opposite to each other. The optical frame 221 is used for installing the lighting module 42. The two fixing plates 222 are respectively arranged on the two first mounting sides. In this way, the lighting module 42 can be installed by setting the optical frame 221. At the same time, the fixing plates 222 can be set to strengthen the strength of the optical frame 221 and reduce the probability of deformation of the optical frame 221.

[0063] It should be noted that the optical frame 221 is the main structural part of the optical rack 22, and is usually designed as a frame on which the lighting module 42 can be installed. It is used to install the lighting module 42, wherein the prism of the lighting module 42 is installed in the optical rack 22, and the LED panel of the lighting module 42 is arranged on the peripheral side of the optical frame 221 and between the two first installation sides. The function of the fixing plate 222 is to further strengthen the structure of the optical rack 22 and ensure the stability of the optical rack 22 during installation and operation. The fixing plate 222 can be connected to the optical frame 221 by screws, welding or other connection methods.

[0064] Furthermore, in one embodiment, one of the two fixing plates 222 is provided with a glue hole so that the assembler can glue and fix the lighting module 42. Furthermore, the other fixing plate 222 is provided with a plurality of adjustment holes at intervals so as to adjust the prism of the lighting module 42 so that the optical performance of the AR glasses can meet the requirements.

[0065] In one embodiment of the present invention, the frame structure 100 also includes a protective cover 3 covering the optical machine mounting part 2. In this way, by providing the protective cover 3, the optical machine mounting part 2 is hidden in the protective cover 3 to prevent the optical machine 4 of the AR glasses from being affected by the external environment.

[0066] It should be noted that there are many ways to connect the shield 3 to the frame body 1. The shield 3 can be installed on the frame body 1 by welding, bonding, screws, etc., and the present invention does not limit this. Furthermore, there are many materials for the shield 3, for example, it can be a plastic cover, a metal cover, or a ceramic cover, as long as it can cover the optical machine mounting part 2, and the present invention does not limit this.

[0067] The present invention further provides an AR glasses, which include a frame structure 100, two optical machines 4 and two waveguides 5, wherein the frame structure 100 includes the frame structure 100 described above, each of the optical machines 4 includes an imaging module 41 and an illumination module 42, the imaging module 41 and the illumination module 42 are arranged on the optical machine mounting portion 2 of the frame structure 100, and the two waveguides 5 are arranged on the frame body 1 of the frame structure 100. Since the AR glasses adopt all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0068] In one embodiment of the present invention, the frame structure 100 includes an optical frame 221, the optical frame 221 includes two first mounting sides arranged opposite to each other, and a plurality of second mounting sides located between the two first mounting sides, the lighting module 42 includes a prism and a plurality of LED panels 421, the prism is arranged in the optical frame 221, the plurality of LED panels 421 include a red panel, a green panel and a blue panel respectively arranged on the plurality of second mounting sides, the red panel is used to emit red light, the green panel is used to emit green light, and the blue panel is used to emit blue light, so that the lighting module 42 can emit light of different colors by arranging the red panel, the green panel and the blue panel, and the prism is arranged so that the light emitted by the plurality of LED panels 421 can be emitted into the waveguide 5 through the imaging module 41 to form a color image.

[0069] It can be understood that there are many ways to form a color image. In other embodiments, the multiple LED panels 421 include a magenta panel, a yellow panel and a cyan panel. The magenta panel is used to emit magenta light, the yellow panel is used to emit yellow light, and the cyan panel is used to emit cyan light. As long as it can be used to form a color image, the present invention is not limited to this.

[0070] See also Figure 7 , Figure 7 This is a first flow chart of the calibration method for AR glasses provided by the present invention.

[0071] The calibration method of the AR glasses includes:

[0072] S10: preparation step: setting a target at a preset calibration position, and placing two cameras at preset positions inside the frame body 1, wherein the two cameras are respectively set corresponding to the outcoupling regions of the two waveguides 5;

[0073] It should be noted that the target may have a variety of shapes, such as a cross shape or a square shape, and the present invention does not limit this.

[0074] S20: Fusion optimization step: turning on the lighting module 42 so that the lighting module 42 projects a projection target, and adjusting the center position of the lighting module 42 so that the projection target coincides with the target target;

[0075] It should be noted that, in theory, the shapes of the projection target and the target target may be different or may be different. If the shapes of the target target and the projection target are different, then when the center of the projection target coincides with the center of the target target, it is considered that the projection target coincides with the target target. However, in order to ensure the fusion quality, the projection target and the target target should adopt the same shape so that the projection target can completely coincide with the target target.

[0076] S30: Pixel optimization step: controlling the center position of the lighting module 42 to remain unchanged, adjusting the distance between the lighting module 42 and the optical machine frame 221 and the angle of the lighting module 42 so that the pixels of the imaging module 41 meet the requirements.

[0077] It should be noted that traditional pixel optimization is usually achieved by adjusting the spacing of the lenses in the imaging module 41, and the imaging module 41 is installed in the optical channel 211. The distance between the lenses is mainly adjusted by the skirt or spacing ring of the lens. It is difficult to accurately adjust the spacing of the lenses, resulting in poor imaging effect and imaging quality that is difficult to meet the use requirements. Compared with the imaging module 41, the lighting module 42 is arranged on the outer peripheral side of the optical machine frame 221, and its adjustment difficulty is relatively small, and it is easier to accurately adjust the position of the lighting module 42. Therefore, in this embodiment, the pixels are optimized by adjusting the lighting module 42, which can greatly improve the imaging quality.

[0078] In this embodiment, the preset target is set so that the waveguide 5 and the optical machine 4 can be optimized later, the camera is set so as to obtain the image output by the waveguide 5, and the center positions of the multiple LED panels 421 are adjusted so as to complete pixel fusion and image fusion. At the same time, the inclination angle of the lighting module 42 and the distance between it and the optical machine frame 221 are adjusted so as to complete the pixel optimization of the AR glasses and improve the imaging quality. After the optical machine 4 and the waveguide 5 are assembled to the frame body 1, the waveguide 5 and the optical machine 4 are calibrated at the same time, so that the AR glasses can be calibrated using a set of active alignment equipment, which can not only save the assembly process of the frame structure 100 and save time, but also reduce the assembly cost.

[0079] Further, the lighting module 42 includes a plurality of LED panels 421, and the plurality of LED panels 421 include a red panel, a green panel and a blue panel;

[0080] Step S20 includes:

[0081] S21: Open the red panel, the green panel and the blue panel respectively in a set order, control the red panel, the green panel and the blue panel to project the projection targets respectively, and adjust the center positions of the red panel, the green panel and the blue panel respectively so that the respective projection targets overlap with the target targets.

[0082] It should be noted that the center position of the lighting module 42 refers to the projection position of each LED panel 421 on the prism. Furthermore, the fusion includes pixel fusion between the multiple LED panels 421 and image fusion between the optical machine 4 and the waveguide 5. There are many setting orders, for example, the red panel, the green panel and the blue panel can be turned on in sequence, or the green panel, the red panel and the blue panel can be turned on in sequence, etc., and the present invention does not limit this.

[0083] In this embodiment, since there are many ways of fusion optimization, the multiple LED panels 421 can be adjusted simultaneously, or each LED panel 421 can be adjusted individually. However, if multiple LED panels 421 are calibrated at the same time, it is difficult to lock the specific panel that needs to be adjusted, and errors are prone to occur. Therefore, by setting the order of the red panel, the green panel and the blue panel, so that each panel can be calibrated separately, the probability of position adjustment errors can be reduced, thereby helping to improve calibration efficiency.

[0084] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
