[0002] With the development of wearable devices, more and more wearable devices have the function of taking images. When taking images through smart glasses, in order to allow users to frame within the field of view, it is necessary to display the images within and outside the framing range to the user at the same time. In the related art, smart glasses need to use display components or external devices to feedback the framing range to the user. Since smart glasses need to be easy for users to wear, they cannot be too heavy, which leads to the small battery capacity of smart glasses in the related art. If the framing range is displayed through its own display component, the power consumption of the smart glasses will increase; if an external device is used to display the framing range, the cost of the smart glasses will increase.

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0026] The embodiments of the present application provide a method, device, computer equipment and computer-readable storage medium for acquiring image information of smart glasses.

[0027] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Please refer to Figure 1 , Figure 1 A flowchart of a method for acquiring image information of smart glasses provided in an embodiment of the present application. The method for acquiring image information of smart glasses can be used in smart glasses to realize shooting of a framing area within a field of view through the smart glasses. The image information obtained by the method for acquiring image information of smart glasses provided in an embodiment of the present application can be a single-frame photo file or a multi-frame video file.

[0029] like Figure 1 As shown, the image information acquisition method of the smart glasses includes steps S101 to S104.

[0030] Step S101: Obtain an image framing instruction.

[0031] For example, the viewport generally refers to the area where a camera captures images, which defines the range of the camera's field of view. Since smart glasses do not have an available viewport, when using the shooting function of the smart glasses, it is difficult for users to distinguish which content within the field of view is within the camera's framing range, and thus they cannot be completely confident in taking the photos they think they have taken.

[0032] In the related art, the viewing range of the camera of the smart glasses is usually displayed through the display component of the smart glasses themselves or an external device, so that the user can observe the field of view and the viewing range at the same time, and adjust the viewing range of the camera within the field of view of the smart glasses, so as to capture the image corresponding to the viewing range through the smart glasses. However, this method is complicated to operate, resulting in increased power consumption of the smart glasses, and has a high hardware cost.

[0033] Based on this, the present application proposes a method for acquiring image information of smart glasses. When an image framing instruction is obtained, the framing area and non-framing area within the field of view are displayed based on different transmittances, thereby reducing the energy consumption and cost of displaying the framing range through smart glasses.

[0034] Exemplarily, the image framing instruction may be an instruction for the user to start a photo taking function or a video recording function of the smart glasses.

[0035] Step S102: determining framing range information according to the image framing instruction, wherein the framing range information is used to indicate a framing area and a non-framing area within a field of view of the smart glasses.

[0036] Exemplarily, when the position of the camera is determined, the camera's framing range is related to the parameters of the camera itself, and the framing area and the non-framing area outside the framing area can be determined within the field of view according to the camera's parameters, such as the camera's focal length, aperture and other adjustable parameters and inherent parameters such as the image sensor size. Specifically, the camera-related parameters can be carried in the image framing instruction and transmitted to the processor of the smart glasses, so that the processor can calculate the framing area based on the camera parameters and a preset algorithm, wherein the algorithm for calculating the framing range can refer to the calculation method in the relevant technology, which will not be described in detail here.

[0037] In some implementations, the image framing instruction includes a field of view angle and an imaging depth of field, and determining the framing range information according to the image framing instruction includes:

[0038] Acquire preset target distance information, where the target distance information is used to reflect the distance between the corneal vertex and the lens of the smart glasses;

[0039] Determining width information and height information of the framing area according to the target distance information, the field of view angle, and the imaging depth of field;

[0040] The positions corresponding to the framing area and the non-framing area are determined within the field of view according to the width information and the height information, wherein the positions within the field of view that do not belong to the framing area belong to the non-framing area.

[0041] Exemplarily, the field of view is the range observed by the user's eyes through the smart glasses lens, so the field of view is related to the distance between the user's eyes and the smart glasses lens. It can be understood that when the user wears smart glasses, the size of the target distance information between the corneal vertex and the smart glasses lens is within a certain numerical range, so the target distance information can be pre-set; or, the target distance information between the user's corneal vertex and the smart glasses lens can be detected by a distance sensor, which is not limited here. Among them, the target distance information is the distance between the position on the smart glasses closest to the corneal vertex and the corneal vertex.

[0042] Exemplarily, the framing range is the range of the image captured by the camera of the smart glasses, which is related to the field of view (FOV) and imaging depth of field (DoF) of the camera. Therefore, the processor can calculate the width and height of the framing area within the field of view according to the target distance information, the field of view and the imaging depth of field, thereby determining the position of the framing area within the field of view. Among them, the field of view is the angle range that the lens can receive the image, which directly determines the field of view of the camera. The larger the field of view, the wider the area that the camera can cover; the imaging depth of field indicates the range within which the image of the object formed on the imaging plane (usually the camera's photosensitive element or film) can remain relatively clear within a certain distance.

[0043] Of course, it is not limited to this, and the shape of the framing area may also be other shapes, such as a circle, which is not limited here.

[0044] The image acquired by the camera of the smart glasses is projected into the field of view according to FOV and DoF, thereby determining the framing range and the non-framing range, so as to facilitate the subsequent display of the framing range and the non-framing range to the user based on different transmittances.

[0045] In some implementations, determining the width information and height information of the framing area according to the target distance information, the field of view angle, and the imaging depth of field includes:

[0046] Calculate the camera field of view width and camera field of view height of the smart glasses according to the field of view angle and the imaging depth of field;

[0047] The camera field of view width and the camera field of view height are converted into width information and height information of the framing area according to the target distance information.

[0048] For example, the camera's field of view width and camera field of view height can be calculated based on FOV and DoF, and then the camera's field of view width and camera field of view height can be projected into the user's field of view based on the target distance information, thereby obtaining the width information and height information of the framing area within the user's field of view.

[0049] Exemplarily, the framing area with width information and height information obtains rectangular image information, which is more in line with the user's usage habits and image information storage habits, thereby improving the user experience.

[0050] In some embodiments, the field of view angle includes a horizontal field of view angle and a vertical field of view angle; and the step of calculating the camera field of view width and camera field of view height of the smart glasses according to the field of view angle and the imaging depth of field includes:

[0051] Calculate the camera field of view width of the smart glasses according to the horizontal field of view angle and the imaging depth of field;

[0052] The camera field of view height of the smart glasses is calculated according to the vertical field of view angle and the imaging depth of field.

[0053] Specifically, the camera field of view width and the camera field of view height are calculated according to the following formula:

[0054] W′=2*DOF*tan(FOV W / 2)

[0055] H′=2*DOF*tan(FOV H / 2)

[0056] Where W' represents the width of the camera's field of view, H' represents the height of the camera's field of view, DOF represents the depth of field, FOV W Indicates the horizontal field of view, FOV H Indicates the vertical field of view.

[0057] Exemplarily, the size of the field of view angle is usually determined by the focal length of the camera. The shorter the focal length, the larger the field of view angle; and the longer the focal length, the smaller the field of view angle; in addition, the size of the camera sensor will also affect the final field of view angle. Therefore, the field of view angle can be determined based on the focal length, sensor and other information in the image framing instruction. Among them, the field of view angle describes the entire three-dimensional space area that the camera lens can capture, usually including two dimensions of width and height, namely the horizontal field of view angle and the vertical field of view angle. For the same camera, the ratio between the horizontal field of view angle and the vertical field of view angle is usually determined, such as 4:3, so one of the two can be determined based on the proportional relationship. The other.

[0058] Exemplarily, the imaging depth of field refers to the range of distances in front and behind the object measured by the front edge of the camera lens or other imager that can obtain a clear image. The depth of field is related to the lens aperture, lens focal length, shooting distance, etc. The imaging depth of field can be calculated based on the lens aperture, lens focal length, shooting distance, etc. in the image framing instruction, thereby calculating the field of view angle width information and field of view height width information.

[0059] In some implementations, converting the camera field of view width and the camera field of view height into width information and height information of the framing area according to the target distance information includes:

[0060] The camera field of view width and the camera field of view height are converted into the width information and the height information of the framing area according to the following formula:

[0061] W=W′*d / DOF

[0062] H=H′*d / DOF

[0063] Wherein, W represents the width information of the framing area, H represents the height information of the framing area, W' represents the width of the camera field of view, H' represents the height of the camera field of view, d represents the target distance information, and DOF represents the imaging depth of field.

[0064] Exemplarily, according to the above formula, the camera field of view width and camera field of view height are mapped to the lens whose distance from the user's eyes is the target distance information, thereby obtaining the width information and height information of the framing area within the field of view. The origin of the framing area can be set by the user, for example, the user can adjust the position of the framing area within the field of view through gestures.

[0065] Please refer to Figure 2 , 3 , Figure 2 , 3 A diagram of a usage scenario of a method for acquiring image information of smart glasses provided in one embodiment of the present application.

[0066] like Figure 2 , 3 As shown, Figure 2 The cone in the figure is the simulated viewing angle range of the camera with an 80° viewing angle. Based on the depth of field of 1 meter, the corresponding field of view of the human eye is deduced. The corresponding viewfinder range on the lens is as follows: Figure 3 As shown, an area with an aspect ratio of 4:3 is selected from the viewfinder as the viewfinder area, but it is certainly not limited thereto, and the aspect ratio of the viewfinder area may also be 16:9 or circular.

[0067] Step S103: adjust the transmittance of the smart glasses lens based on the framing range information, so that a first transmittance of a first area of ​​the smart glasses lens corresponding to the framing area is greater than a second transmittance of a second area of ​​the smart glasses lens corresponding to the non-framing area.

[0068] Exemplarily, the transmittance of eyeglass lenses refers to the degree of loss of light when passing through the lenses, also known as transparency or light transmittance. Lenses with high transmittance can better transmit light, making vision clearer and brighter, while lenses with low transmittance will cause dim vision and color distortion. By adjusting the transmittance of smart glasses lenses, the framing area and the non-framing area appear different brightness to the user. Specifically, the first transmittance of the first area is greater than the second transmittance of the second area, even if the brightness of the framing area observed by the human eye is greater than the brightness of the non-framing area, so that the user can intuitively distinguish the images captured by the camera.

[0069] In some implementations, adjusting the light transmittance of the smart glasses lens based on the viewing range information includes:

[0070] Based on the framing range information, a second light transmittance of the second area is reduced; and / or,

[0071] The first light transmittance of the first area is increased based on the viewing range information.

[0072] Exemplarily, since the framing range information is used to indicate the framing area and the non-framing area within the field of view of the smart glasses, the first area corresponding to the framing area and the second area corresponding to the non-framing area can be determined according to the framing range information, so that the first transmittance is greater than the second transmittance by reducing the second transmittance or increasing the first transmittance. Of course, it is not limited to this, and the first transmittance can also be increased while reducing the second transmittance.

[0073] For example, in actual use, in order to ensure the visual experience, the transmittance of the lens is usually the maximum transmittance that can be achieved, and the first transmittance cannot be increased any further. Therefore, the first transmittance is made greater than the second transmittance by directly reducing the second transmittance of the second area.

[0074] Specifically, the transmittance of the first area and the second area can be adjusted by an electrical signal, for example, by applying different electrical signals to the first area and / or the second area respectively, so as to adjust the transmittance of the electrochromic material on the first area and / or the second area, so that the colors of the framing area and the non-framing area present different shades, and the user can intuitively distinguish the framing area and the non-framing area according to the observed color depth. Among them, the relationship between the transmittance of different types of electrochromic materials and the electrical signal is different, which will not be elaborated here.

[0075] In some embodiments, the light transmittance of the lenses of the smart glasses can be changed according to the electrical signal parameters.

[0076] For example, the lenses of smart glasses can be made of electrochromic materials, which can undergo electrochemical redox reactions under the action of an external electric field, gain or lose electrons, and cause the color of the material to change reversibly. For example, by applying different electric fields to different areas of the lens, different areas on the lens have different light transmittances.

[0077] In some embodiments, the lenses of the smart glasses include an electrochromic layer, and the electrochromic layer is made of at least one of an electrochromic material, a liquid crystal dimming material, and an electronic ink material.

[0078] Exemplarily, the lenses of smart glasses may include an electrochromic layer. During normal use, the transmittance of the electrochromic layer does not change, ensuring that the lenses of the smart glasses have a good transmittance effect and improving the user's visual experience. When obtaining image information through the smart glasses, the transmittance of the lenses of the smart glasses is adjusted through the electrochromic layer, so that the viewing area and the non-viewing area have different transmittances. Among them, the lenses of the smart glasses may also include a display layer, which may be made of an optical waveguide material for total reflection transmission of a virtual image to be displayed; the electrochromic layer may be made of an electrochromic material, but of course it is not limited thereto. The electrochromic layer may also be made of other materials whose transmittance can change with electrical signal parameters, such as a liquid crystal dimming film and an electronic ink screen, which are not limited here.

[0079] Exemplarily, the electrochromic layer is disposed on the surface of the display layer, or the electrochromic layer and the display layer may be disposed integrally, which is not limited here.

[0080] Please refer to Figure 4 , Figure 4 A diagram of a usage scenario of a method for acquiring image information of smart glasses provided in one embodiment of the present application.

[0081] like Figure 4 As shown, the field of view of the smart glasses includes a framing area and a non-framing area, the first area corresponds to the framing area, and the second area corresponds to the non-framing area. The first light transmittance of the first area and the second light transmittance of the second area can be adjusted on a single lens of the smart glasses, or the first light transmittance and the second light transmittance can be adjusted on both lenses, which is not limited here.

[0082] Step S104: based on the image information acquisition instruction, the target image information corresponding to the framing area is acquired based on the adjusted transmittance.

[0083] Exemplarily, the image information acquisition instruction can be used to instruct the smart glasses to capture and store images within the field of view to obtain a target image or an image composed of multiple frames of target images.

[0084] The method for acquiring image information of the smart glasses provided in the above embodiment is as follows: acquiring an image framing instruction; determining framing range information according to the image framing instruction, wherein the framing range information is used to indicate a framing area and a non-framing area within the field of view of the smart glasses; adjusting the transmittance of the smart glasses lens based on the framing range information, so that the first transmittance of the first area of ​​the smart glasses lens corresponding to the framing area is greater than the second transmittance of the second area of ​​the smart glasses lens corresponding to the non-framing area; acquiring the target image information corresponding to the framing area based on the image information acquisition instruction. Since the smart glasses display the framing area and the non-framing area within the field of view based on different transmittances, the user can simply and intuitively distinguish the framing range of the smart glasses camera, thereby having a clear understanding of the image captured by the camera, and reducing the energy consumption and cost of displaying the framing range through the smart glasses.

[0090] The second instruction acquisition module 140 is used to acquire instructions based on the image information and acquire target image information corresponding to the framing area based on the adjusted transmittance.
