[0053] 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.

[0054] 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.

[0055] The embodiment of the present application provides a smart glasses, such as Figure 1 As shown, the smart glasses include:

[0056] The first mirror frame 110 is provided with a reflective surface 112 and a first optical engine 111. The reflective surface 112 and the first optical engine 111 are fixed relative to each other.

[0057] The second mirror frame 120 is provided with a light emitter 122, a light receiver 123 and a second optical engine 121. The relative positions of the light emitter 122, the light receiver 123 and the second optical engine 121 are fixed;

[0058] a processing device electrically connected to the light emitter 122 and the light receiver 123, respectively, for obtaining a standard position of the light spot and a deformed position of the light spot, determining the deformed position of the first optical engine 111 based on the standard position of the light spot and the deformed position of the light spot, and determining a correction amount of the first optical engine 111 based on the standard position of the first optical engine 111 and the deformed position of the first optical engine 111;

[0059] Among them, the light emitted by the light emitter 122 is reflected by the reflecting surface to the light receiver 123 to form a light spot, the standard position of the light spot is the position of the light spot when the smart glasses are not deformed, the deformed position of the light spot is the position of the light spot when the smart glasses are deformed, the standard position of the first optical machine 111 is the position of the first optical machine 111 when the smart glasses are not deformed, and the deformed position of the first optical machine 111 is the position of the first optical machine 111 when the smart glasses are deformed, and the coordinate systems corresponding to the standard position of the light spot, the deformed position of the light spot, the standard position of the first optical machine 111 and the deformed position of the first optical machine 111 are the same and are all coordinate systems corresponding to the light emitter 122, the light generator 123 or the second optical machine 121.

[0060] It should be noted that Figure 1 The processing device is not shown in the figure, and the processing device can be set at any position of the smart glasses that does not block the wearer's field of view. Figure 1 The dashed lines with arrows in the figure respectively indicate the light emitted by the light emitter 122 and the light reflected by the reflecting surface 112.

[0061] Furthermore, the positions of the light emitter 122, the light receiver 123 and the reflective surface 112 may also be as follows: Figure 2 and Figure 3 Of course, the positions of the light emitter 122, the light receiver 123, and the reflective surface 112 can also be other, as long as they meet the limitations of the light emitter 122, the light receiver 123, and the reflective surface 112 in the embodiment of the present application.

[0062] Furthermore, the first optical engine 111 and the reflective surface 112 can be positioned close together to ensure that their relative positions remain fixed regardless of whether the smart glasses are deformed. Furthermore, the second optical engine 121, the optical transmitter 122, and the optical receiver 123 can be positioned close together to ensure that their relative positions remain fixed regardless of whether the smart glasses are deformed.

[0063] In the embodiment of the present application, the first frame is the frame corresponding to the left lens of the smart glasses, and the second frame is the frame corresponding to the right lens of the smart glasses. Alternatively, the first frame is the frame corresponding to the right lens of the smart glasses, and the second frame is the frame corresponding to the left lens of the smart glasses.

[0064] For example, if the first frame corresponds to the right lens of the smart glasses, the first optical engine 111 is the optical engine for the right lens, and is used to project an image onto the right lens based on the display signal of the right lens. Furthermore, the second optical engine 121 is the optical engine for the left lens, and is used to project an image onto the left lens based on the display signal of the left lens.

[0065] The light emitter 122 is configured to emit light toward the reflective surface 112. The reflective surface 112 is configured to reflect the light emitted by the light emitter 122. The light reflected by the reflective surface 112 forms a light spot on the light receiver 123. The light receiver 123 is configured to sense the light spot formed thereon.

[0066] In the embodiment of the present application, when the smart glasses are worn, there is a possibility that the smart glasses will be deformed due to differences in the wearer's face. Figure 1 As shown, the deformed area 130 is generally the connection between the first frame and the second frame of the smart glasses.

[0067] In the embodiment of the present application, the reference coordinate system of the smart glasses is the coordinate system of the light emitter 122, the light receiver 123, or the second optical engine 121. Taking the reference coordinate system of the smart glasses as the coordinate system of the light emitter 122 as an example, the coordinate origin of the reference coordinate system can be the center point of the light emitter 122.

[0068] Because the relative positions of the second optical engine 121, the light emitter 122, and the light receiver 123 are fixed, and the reference coordinate system of the smart glasses is the coordinate system of the second optical engine 121, the light emitter 122, or the light receiver 123, even if the smart glasses are deformed, the positions of the second optical engine 121, the light emitter 122, and the light receiver 123 in the reference coordinate system do not change. As a result, the image projected by the second optical engine 121 onto the corresponding lens does not shift.

[0069] Continuing with this, when the smart glasses deform, the position of the reflective surface 112 relative to the second optical engine 121 (or light emitter 122, or light receiver 123) changes, and the position of the light spot changes accordingly. Based on this, the changes in the reflective surface 112 can be reflected based on the deformed position of the light spot and its standard position. Furthermore, combined with the standard position of the reflective surface 112, the deformed position of the reflective surface 112 can be determined. Since the reflective surface 112 and the first optical engine 111 are fixed relative to each other, the deformed position of the first optical engine 111 can be determined based on the deformed position of the reflective surface 112.

[0070] Furthermore, based on the difference between the deformed position of the first optical engine 111 and its standard position, the correction amount for the first optical engine 111 can be determined. The first optical engine 111 projects the image onto the corresponding lens based on the correction amount, thus preventing image offset. This eliminates the need to restrict the rigidity of the smart glasses' frames, meeting the requirements for miniaturization and lightweighting of smart glasses.

[0071] The standard position of the light spot can be obtained by calibrating the light spot in the reference coordinate system before the smart glasses leave the factory and are not deformed. Similarly, the standard position of the reflective surface 112 can be obtained by calibrating the reflective surface 112 in the reference coordinate system before the smart glasses leave the factory and are not deformed. Furthermore, the standard position of the first optical engine 111 can be obtained by calibrating the first optical engine 111 in the reference coordinate system before the smart glasses leave the factory and are not deformed.

[0072] In addition, the correction amount of the first optical engine 111 is: the difference between the standard position of the first optical engine 111 and the deformed position of the first optical engine 111 .

[0073] The embodiment of the present application provides smart glasses, comprising: a first frame provided with a reflective surface and a first optical engine, wherein the reflective surface and the first optical engine are fixed relative to each other; a second frame provided with a light emitter, a light receiver, and a second optical engine, wherein the light emitter, the light receiver, and the second optical engine are fixed relative to each other; a processing device electrically connected to the light emitter and the light receiver, respectively, for obtaining a standard position of a light spot and a deformed position of the light spot, determining the deformed position of the first optical engine based on the standard position of the light spot and the deformed position of the light spot, and determining a correction amount for the first optical engine based on the standard position of the light spot and the deformed position of the light spot; wherein light emitted by the light emitter is reflected by the reflective surface to the light receiver to form a light spot. Through the embodiment of the present application, there is no need to limit the rigidity of the frame of the smart glasses, thereby meeting the requirements of miniaturization and lightweighting of the smart glasses.

[0074] In one embodiment of the present application, the processing device is further configured to: obtain a wearing state of the smart glasses; and turn on the light transmitter 122 and the light receiver 123 when the wearing state is wearing.

[0075] The wearing status of smart glasses includes wearing and not wearing.

[0076] In the embodiment of the present application, if the wearing state is "wearing," it indicates that the smart glasses may be in use. At this point, the light emitter 122 and the light receiver 123 are turned on to determine the correction amount for the first optical engine 111. This avoids ineffective activation of the light emitter 122 and the light receiver 123.

[0077] Correspondingly, when the wearing state is not worn, it means that the smart glasses are not likely to be used. At this time, the light transmitter 122 and the light receiver 123 are turned off. This can save power consumption of the smart glasses.

[0078] The wearer may inform the smart glasses of the wearing status of the smart glasses through voice input or key input.

[0079] In order to enable the smart glasses to actively detect their own wearing status and improve the intelligence of the smart glasses, the smart glasses provided in the embodiment of the present application further include:

[0080] The wearing detection device is arranged at a position where the smart glasses contact the wearer when the smart glasses are worn, and is electrically connected to the processing device.

[0081] In the embodiment of the present application, the wearing detection device may be a pressure sensor. Since the wearing detection device is disposed at a location where the smart glasses contact the wearer when the smart glasses are in the wearing state, if the pressure value detected by the pressure sensor is greater than 0, the wearing state of the smart glasses is determined to be wearing, otherwise, the wearing state of the smart glasses is determined to be not wearing.

[0082] Of course, the wearing detection device can also be other types, such as a distance sensor.

[0083] In one embodiment of the present application, the processing device for determining the deformed position of the first optical engine 111 according to the standard position of the light spot and the deformed position of the light spot may include the following steps:

[0084] S1. Determine the rotation angle of the reflecting surface 112 according to the standard position of the light spot and the deformed position of the light spot;

[0085] S2. Determine the deformation position of the reflecting surface 112 according to the rotation angle and the standard position of the reflecting surface 112;

[0086] S3. Determine the deformation position of the first optical engine 111 according to the deformation position of the reflective surface 112.

[0087] It should be noted that, in the embodiment of the present application, the light emitter 122 and the light reflector are located in the same plane, and the plane where the light emitter 122 is located is parallel to the plane where the reflective surface 112 is located.

[0088] like Figure 4 As shown, for the above S1, combined with the principle of light reflection and trigonometric functions, the calculation process of the rotation angle of the reflective surface 112 is as follows:

[0089] a=c / 2 (Formula 1);

[0090] θ = arctg(a / b) (Formula 2);

[0091] θ′=arctg(a′ / b) (Formula 3);

[0092]

[0093] Wherein, c is the distance between the light emitter 122 and the standard position of the light spot;

[0094] a is half the distance between the light emitter 122 and the standard position of the light spot;

[0095] a' is the sum of a and the change in the light spot after the smart glasses are deformed. The change in the light spot refers to the offset of the light spot position when the smart glasses are deformed relative to the light spot position when the smart glasses are not deformed.

[0096] b is the distance between the plane where the light emitter 122 is located and the plane where the reflective surface 112 is located;

[0097] θ is the light reflection angle when the smart glasses are not deformed;

[0098] θ' is the angle between the reflected light when the smart glasses are deformed and the normal of the reflecting surface 112 when the smart glasses are not deformed;

[0099] is the rotation angle of the reflecting surface 112 .

[0100] Regarding S2, based on the standard position of the reflective surface 112, the reflective surface 112 is rotated in a set direction by the rotation angle determined in S1 to determine the deformed position of the reflective surface 112. The set direction is the direction of deformation of the smart glasses when worn. It will be appreciated that this direction is typically fixed.

[0101] Regarding the above S3 , the deformation position of the first optical engine 111 is determined according to the relative positional relationship between the reflective surface 112 and the first optical engine 111 and the deformation position of the reflective surface 112 .

[0102] According to the relative position relationship between the reflective surface 112 and the first optical engine 111 , the value can be obtained according to the ratio between the standard position of the reflective surface 112 and the standard position of the first optical engine 111 .

[0103] It should be noted that Figure 4 The solid circle in is the actual position of the light spot when the smart glasses are not deformed, that is, the standard position of the light spot. Figure 4 The dotted circle in is the actual position of the light spot when the smart glasses are deformed, that is, the light spot deformation position. Figure 4 The dotted line with an arrow in the figure is the reflected light after the smart glasses are deformed. Figure 4 The dotted rectangle in the figure is the position of the smart glasses after deformation.

[0104] In one embodiment of the present application, the light emitter 122 is an infrared light emitter or a laser emitter, or other light emitters with high collimation.

[0105] When the light emitter 122 is an infrared light emitter or a laser emitter, the cost of the smart glasses provided in the embodiment of the present application can be reduced.

[0110] The light emitted by the light emitter is reflected by the reflective surface to the light receiver to form the light spot.
