[0049] At present, the assembly of AR glasses is generally divided into two steps: optical machine assembly and whole machine assembly. However, since the AR glasses usually need to be calibrated by active alignment equipment to meet the optical performance requirements, a set of active alignment equipment is needed to calibrate the optical machine during optical machine assembly to solve the problems of dark edge or pixel of the optical machine. Another set of active alignment equipment is needed to calibrate the whole machine during whole machine assembly to solve the problem of combined image of the optical machine and the waveguide. Therefore, two sets of active alignment equipment are needed to calibrate the AR glasses during assembly, which leads to complicated assembly process and high cost of the AR glasses.

[0050] Therefore, the present application provides a spectacle frame structure for AR glasses, which aims to optimize the complicated assembly process and high cost of the existing AR glasses. In the present application, Figures 1 to 7 The schematic diagram of the AR glasses and the calibration method thereof provided by the present application is shown in the figure.

The other end of the optical channel penetrates the free end of the optical machine mounting portion 2, and the free end of the optical machine mounting portion 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 user's eyes. The waveguide 5 is a key optical component for transmitting digital images from a micro display to the user's eyes to combine virtual images from the light engine 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) using total internal reflection to achieve effective transmission of image information. The light engine 4 of the AR glasses usually refers to the optical engine or display module, which is a key component responsible for generating and projecting images into the user's field of view, including the imaging module 41 and the illumination module 42.

[0053] The technical scheme of the present application sets the frame body 1 to form two mounting areas, sets mounting holes 11 in each mounting area to mount the waveguide 5 to the frame body 1, and sets the light engine mounting portion 2 to mount the imaging module 41 and the illumination module 42, while the frame body 1 and the light engine mounting portion 2 are integrally arranged to assemble the waveguide 5 and the light engine 4 together in the frame structure 100, so as to simultaneously calibrate the waveguide 5 and the light engine 4, optimizing step-by-step calibration into synchronous calibration, so that the AR glasses can complete calibration with a set of active alignment equipment, saving the assembly process of the frame structure 100, saving time, and reducing assembly cost.

[0057] Further, in an embodiment, the side wall of the groove 12 is formed with a positioning surface, which is adapted to the side surface of the waveguide 5 to limit the movement of the waveguide 5 on the plane where the frame body 1 is located, in this way, by arranging the positioning surface, the waveguide 5 is limited in the groove 12 to prevent the waveguide 5 from moving on the outer side of 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 an embodiment of the present application, please refer to Figure 4 and Figure 5 The side wall of the groove 12 is provided with a glue dispensing groove 13, 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, by arranging the glue dispensing groove 13, the assembler can dispense glue.

Of course, in other embodiments, the waveguide 5 can also be fixed on the frame body 1 by screws and the like, as long as it can be fixed on the frame body 1, the present application does not limit this.

[0070] Please refer to Figure 7 , Figure 7 The first flow chart of the calibration method of the AR glasses provided by the present application.

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

[0072] S10: Preparation step: set a target target at a preset calibration position, and place two cameras at the inner side of the frame body 1 at the preset position, the two cameras correspond to the coupling-out area of the two waveguides 5 respectively;

[0073] It should be noted that the shape of the target target can be various, which can be cross-shaped, or mouth-shaped, etc., and the present application does not limit it.

[0074] S20: Fusion optimization step: turn on the illumination module 42 to make the illumination module 42 project a projection target, and adjust the center position of the illumination module 42 to make the projection target coincide with the target target;

[0075] It should be noted that theoretically, the shapes of the projection target and the target target can be different, and if the shapes of the target target and the projection target are different, the center of the projection target coincides with the center of the target target, then the projection target coincides with the target target, but in order to ensure the fusion quality, the projection target and the target target are preferably of the same shape, so that the projection target can coincide with the target target completely.

[0076] S30: Pixel optimization step: control the center position of the illumination module 42 to be unchanged, adjust the distance between the illumination module 42 and the light machine frame 221 and the angle of the illumination module 42, so that the pixels of the imaging module 41 meet the requirements.

[0077] It should be noted that the traditional pixel optimization is usually by adjusting the distance between lenses in the imaging module 41 installed in the optical channel 211, and the distance between lenses is mainly adjusted by the skirt or spacer ring of the lens, which is difficult to accurately adjust the distance between lenses, resulting in poor imaging effect and imaging quality difficult to meet the use requirements. Compared with the imaging module 41, the illumination module 42 is arranged on the outer circumferential side of the light machine frame 221, which is less difficult to adjust and easier to accurately adjust the position of the illumination module 42. Therefore, in this embodiment, the pixel is optimized by adjusting the illumination module 42, which can greatly improve the imaging quality.

[0078] In this embodiment, the preset target is set to optimize the waveguide 5 and the light machine 4 subsequently, the camera is set to obtain the image output by the waveguide 5, and the center positions of the plurality of LED panels 421 are adjusted to complete pixel fusion and image fusion. At the same time, the inclination angle of the illumination module 42 and the distance between the illumination module 42 and the light machine frame 221 are adjusted to complete the pixel optimization of the AR glasses and improve the imaging quality. After the light machine 4 and the waveguide 5 are assembled to the frame body 1, the waveguide 5 and the light machine 4 are calibrated at the same time, so that the AR glasses can be calibrated by using a set of active alignment equipment, which can save the assembly process of the frame structure 100, save time, and reduce the assembly cost.

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

[0080] Step S20 includes:

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

[0082] It should be noted that the center position of the illumination module 42 refers to the projection position of each LED panel 421 on the prism. Further, fusion includes pixel fusion between the plurality of LED panels 421 and image fusion between the light machine 4 and the waveguide 5. The set order has many kinds, for example, the red panel, the green panel and the blue panel can be turned on in turn, or the green panel, the red panel and the blue panel can be turned on in turn, etc. The present application does not limit this.

[0083] In the embodiment, since there are multiple fusion optimization modes, the multiple LED panels 421 can be adjusted simultaneously or individually, but if the multiple LED panels 421 are calibrated simultaneously, it is difficult to lock the specific panel to be adjusted, and errors are prone to occur, so the red panel, the green panel and the blue panel are set in sequence to calibrate the panels individually, which can reduce the probability of position adjustment errors, thereby helping to improve the calibration efficiency.

[0084] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made under the technical concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
