Description

Image information acquisition method, device, smart glasses and storage medium

[0001] This application claims priority to Chinese Patent Application No. 2024119771955, filed with the Chinese Patent Office on December 30, 2024, entitled "Image Information Acquisition Method, Apparatus, Smart Glasses and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of display devices, and more particularly to an image information acquisition method, apparatus, smart glasses, and storage medium. Background Technology

[0003] With the development of wearable devices, more and more wearable devices are equipped with image-capturing capabilities. When capturing images through smart glasses, in order to allow the user to frame the shot within their field of view, it is necessary to simultaneously display both the image within and outside the frame. In related technologies, smart glasses need to use display components or external devices to provide feedback on the framing to the user. Because smart glasses need to be easy for users to wear, their weight cannot be too heavy, resulting in relatively small battery capacities in related technologies. If the framing is displayed through the smart glasses' own display components, it would increase power consumption; if an external device is used to display the framing, it would increase the cost of the smart glasses. Summary of the Invention

[0004] The main objective of this application is to provide a method, device, smart glasses, and computer storage medium for acquiring image information for smart glasses, with the aim of reducing energy consumption and cost of displaying the field of view through smart glasses.

[0005] In a first aspect, this application provides a method for acquiring image information of smart glasses, the method comprising the following steps:

[0006] Get image framing instructions;

[0007] The framing range information is determined according to the image framing instruction, and the framing range information is used to indicate the framing area and non-framing area within the field of view of the smart glasses.

[0008] The light transmittance of the smart glasses lens is adjusted based on the framing range information, so that the first light transmittance of the smart glasses lens in the first area corresponding to the framing area is greater than the second light transmittance of the smart glasses lens in the second area corresponding to the non-framing area.

[0009] Based on the image information acquisition instruction, the target image information corresponding to the framing area is acquired based on the adjusted transmittance.

[0010] Secondly, this application also provides an image information acquisition device for smart glasses, the image information acquisition device for smart glasses comprising:

[0011] The first instruction acquisition module is used to acquire image framing instructions;

[0012] The framing range determination module is used to determine framing range information according to the image framing instruction, wherein the framing range information is used to indicate the framing area and non-framing area within the field of view of the smart glasses;

[0013] A light transmittance adjustment module is used to adjust the light transmittance of the smart glasses lens based on the framing range information, so that the first light transmittance of the smart glasses lens in the first area corresponding to the framing area is greater than the second light transmittance of the smart glasses lens in the second area corresponding to the non-framing area.

[0014] The second instruction acquisition module is used to acquire instructions based on image information and to acquire target image information corresponding to the framing area based on the adjusted transmittance.

[0015] Thirdly, this application also provides a smart glasses, the smart glasses including a processor, a memory, and a computer program stored in the memory and executable by the processor, wherein when the computer program is executed by the processor, it implements the image information acquisition method of the smart glasses as described above.

[0016] Fourthly, this application also provides a computer-readable storage medium storing a computer program, wherein when the computer program is executed by a processor, it implements the image information acquisition method for smart glasses as described above.

[0017] This application provides an image information acquisition method, device, smart glasses, and computer storage medium for smart glasses. The application acquires an image framing command; determines framing range information based on the image framing command, the framing range information indicating the framing area and non-framing area within the field of view of the smart glasses; adjusts the light transmittance of the smart glasses lens based on the framing range information, such that a first light transmittance of the smart glasses lens in a first area corresponding to the framing area is greater than a second light transmittance of the smart glasses lens in a second area corresponding to the non-framing area; and acquires target image information corresponding to the framing area based on the adjusted light transmittance, according to the image information acquisition command. Because the smart glasses display the framing area and non-framing area within the field of view based on different light transmittance levels, users can easily and intuitively distinguish the framing range of the smart glasses camera, thus gaining 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.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0027] This application provides an image information acquisition method, device, smart glasses, and computer-readable storage medium for smart glasses.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figure 1, which is a flowchart illustrating an image information acquisition method for smart glasses according to an embodiment of this application. This image information acquisition method for smart glasses can be used in smart glasses to capture images of the viewfinder area within the smart glasses' field of vision. The image information obtained by the image information acquisition method for smart glasses provided in this embodiment can be a single-frame photograph file or a multi-frame video file.

[0030] As shown in Figure 1, the image information acquisition method of the smart glasses includes steps S101 to S104.

[0031] Step S101: Obtain image framing instructions.

[0032] For example, a viewport typically refers to the area where a camera captures an image, defining the range of the camera's field of view. However, since smart glasses do not have a viewport available, when using the smart glasses' shooting function, users have difficulty distinguishing which content within their field of view is within the camera's frame, thus making it impossible to take photos they believe they have taken with complete confidence.

[0033] In related technologies, the field of view of the smart glasses' camera is typically displayed through the smart glasses' own display components or external devices. This allows users to simultaneously observe both the field of view and the framing, and adjust the camera's framing within the smart glasses' field of view to capture an image corresponding to that framing. However, this method is complex, leading to increased power consumption and higher hardware costs for the smart glasses.

[0034] Based on this, this application proposes an image information acquisition method for 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 transmittance, thereby reducing the energy consumption and cost of displaying the framing range through smart glasses.

[0035] For example, an image framing command could be a command for the user to activate the smart glasses' photo-taking or video-recording functions.

[0036] Step S102: Determine the framing range information according to the image framing instruction. The framing range information is used to indicate the framing area and non-framing area within the field of view of the smart glasses.

[0037] For example, when the camera's position is fixed, the camera's field of view is related to the camera's parameters. The framing area and the non-framing area outside the framing area can be determined based on these parameters, such as adjustable parameters like the camera's focal length and aperture, and inherent parameters like the image sensor size. Specifically, camera-related parameters can be carried in the image framing command and transmitted to the smart glasses' processor. The processor then calculates the framing area based on a preset algorithm using the camera's parameters. The algorithm for calculating the framing area can refer to calculation methods in related technologies and will not be elaborated upon here.

[0038] In some implementations, the image framing command includes a field of view and an imaging depth of field, and determining the framing range information based on the image framing command includes:

[0039] Obtain preset target distance information, which reflects the distance between the corneal vertex and the smart glasses lens;

[0040] Based on the target distance information, the field of view, and the imaging depth, the width and height information of the framing area are determined;

[0041] Based on the width information and the height information, the positions corresponding to the framing area and the non-framing area are determined within the field of view, wherein the positions within the field of view that do not belong to the framing area belong to the non-framing area.

[0042] For example, the field of view is the range observed by the user's eyes through the lenses of the smart glasses. Therefore, the field of view is related to the distance between the user's eyes and the lenses of the smart glasses. It is understood that when a user wears smart glasses, the target distance information between the corneal apex and the smart glasses lenses is within a certain numerical range. Therefore, the target distance information can be preset; alternatively, it can be detected by a distance sensor. This is not limited here. The target distance information is the distance between the closest point on the smart glasses to the corneal apex and the corneal apex itself.

[0043] For example, the field of view (FOV) is the area captured by the camera of the smart glasses, which is related to the camera's field of view (FOV) and depth of field (DoF). Therefore, the processor can calculate the width and height of the FOV area within the field of view based on the target distance information, FOV, and DoF, thereby determining the position of the FOV area within the field of view. The FOV is the angular range that the lens can receive images from, directly determining the camera's field of view; the larger the FOV, the wider the area the camera can cover. The DoF represents the range within which the image of a subject at a certain distance remains relatively sharp on the imaging plane (usually the camera's sensor or film).

[0044] Of course, it is not limited to this. The shape of the framing area can also be other shapes, such as a circle. There is no limitation here.

[0045] Based on FOV and DoF, the images captured by the smart glasses' camera are projected into the field of view to determine the framing range and non-framing range, which facilitates the subsequent display of the framing range and non-framing range to the user based on different light transmittance.

[0046] In some implementations, determining the width and height information of the framing area based on the target distance information, the field of view, and the imaging depth includes:

[0047] The camera field of view width and camera field of view height of the smart glasses are calculated based on the field of view angle and the imaging depth.

[0048] Based on the target distance information, the camera's field of view width and camera's field of view height are converted into the width and height information of the framing area.

[0049] For example, the camera's field of view width and height can be calculated first based on FOV and DoF, and then the camera's field of view width and height can be projected into the user's field of view based on the target distance information, thereby obtaining the width and height information of the framing area within the user's field of view.

[0050] For example, a viewfinder with width and height information can capture rectangular image information, which is more in line with user habits and image storage habits, thus improving the user experience.

[0051] In some embodiments, the field of view includes a horizontal field of view and a vertical field of view; the step of calculating the camera field of view width and camera field of view height of the smart glasses based on the field of view and the imaging depth includes:

[0052] The camera field of view of the smart glasses is calculated based on the horizontal field of view and the imaging depth.

[0053] The camera field of view height of the smart glasses is calculated based on the vertical field of view and the imaging depth.

[0054] Specifically, the tangent of half the horizontal field of view is calculated, and then multiplied by twice the imaging depth to obtain the camera's field of view width of the smart glasses; the tangent of half the vertical field of view is calculated, and then multiplied by twice the imaging depth to obtain the camera's field of view height of the smart glasses. For example, the camera's field of view width and field of view height can be calculated using the following formula: W′=2*DOF*tan(FOV) W / 2) H′=2*DOF*tan(FOV H / 2)

[0055] Where W' represents the camera's field of view width, H' represents the camera's field of view height, DOF represents the imaging depth of field, and FOV represents the field of view depth. W FOV represents the horizontal field of view. H Indicates the vertical field of view.

[0056] For example, the size of the field of view is usually determined by the focal length of the camera; the shorter the focal length, the larger the field of view; conversely, the longer the focal length, the smaller the field of view. Furthermore, the size of the camera sensor also affects the final field of view. Therefore, the field of view can be determined based on information such as the focal length and sensor size in the image framing instructions. The field of view describes the entire three-dimensional spatial area that the camera lens can capture, typically including two dimensions: width and height, namely the horizontal field of view and the vertical field of view. For the same camera, the ratio between the horizontal and vertical field of view is usually fixed, for example, 4:3; therefore, the other can be determined based on the ratio.

[0057] For example, imaging depth of field refers to the range of distances in front of and behind a subject that can be captured in a sharp image by the front edge of a camera lens or other imager. The size of 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 information such as lens aperture, lens focal length, and shooting distance in the image framing command, thereby calculating the field of view width and field of view height information.

[0058] In some implementations, converting the camera's field of view width and camera's field of view height into the width and height information of the framing area based on the target distance information includes: dividing the target distance information by the imaging depth of field to obtain a conversion coefficient; multiplying the camera's field of view width by the conversion coefficient to obtain the width information of the framing area; and multiplying the camera's field of view height by the conversion coefficient to obtain the height information of the framing area. For example, the camera's field of view width and camera's field of view height can be converted into the width and height information of the framing area using the following formulas: W = W′*d / DOF H = H′*d / DOF

[0059] Where W represents the width of the viewfinder, H represents the height of the viewfinder, W' represents the width of the camera's field of view, H' represents the height of the camera's field of view, d represents the target distance information, and DOF represents the depth of field.

[0060] For example, the camera's field of view width and height are mapped onto a lens whose distance from the user's eyes is the target distance information, according to the above formula, thereby obtaining the width and height information of the viewfinder area within the field of view. The origin of the viewfinder area can be set by the user; for example, the user can adjust the position of the viewfinder area within the field of view using gestures.

[0061] Please refer to Figures 2 and 3, which are usage scenario diagrams of an image information acquisition method for smart glasses provided in an embodiment of this application.

[0062] As shown in Figures 2 and 3, the cone in Figure 2 represents the simulated field of view of the camera at an 80° angle. Based on a depth of field of 1 meter, the corresponding field of view for the human eye is deduced, and the corresponding framing area on the lens is shown in Figure 3. An area with an aspect ratio of 4:3 is selected from this framing area as the viewing area. However, this is not limited to this; the aspect ratio of the viewing area can also be 16:9 or circular.

[0063] Step S103: Adjust the light transmittance of the smart glasses lens based on the framing range information, so that the first light transmittance of the smart glasses lens in the first region corresponding to the framing area is greater than the second light transmittance of the smart glasses lens in the second region corresponding to the non-framing area.

[0064] For example, the light transmittance of eyeglass lenses refers to the degree of light loss when passing through the lens, also known as transparency or light transmission. Lenses with high light transmittance can transmit light better, making vision clearer and brighter, while lenses with low light transmittance will result in a dim field of vision and color distortion. By adjusting the light transmittance of the smart eyeglass lenses, the viewing area and the non-viewing area can present different brightness levels to the user. Specifically, the first light transmittance of the first area is greater than the second light transmittance of the second area, so that the brightness of the viewing area observed by the human eye is greater than the brightness of the non-viewing area, thus allowing the user to intuitively distinguish the image captured by the camera.

[0065] In some embodiments, adjusting the light transmittance of the smart glasses lenses based on the field of view information includes:

[0066] Reduce the second transmittance of the second region based on the framing information; and / or,

[0067] The first transmittance of the first region is increased based on the framing range information.

[0068] For example, since the framing range information is used to indicate the framing area and 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 based on the framing range information. Thus, by reducing the second light transmittance or increasing the first light transmittance, the first light transmittance can be made greater than the second light transmittance. Of course, it is not limited to this; it is also possible to increase the first light transmittance while reducing the second light transmittance.

[0069] For example, in actual use, in order to ensure visual experience, the light transmittance of the lens is usually the maximum light transmittance that can be achieved. The first light transmittance cannot be increased further. Therefore, the first light transmittance is made greater than the second light transmittance by directly reducing the second light transmittance of the second region.

[0070] Specifically, the light transmittance of the first and second regions can be adjusted by electrical signals. For example, by applying different electrical signals to the first and / or second regions respectively, the light transmittance of the electrochromic material in the first and / or second regions can be adjusted, thereby causing the viewfinder and non-viewfinder areas to exhibit different shades of color. Users can intuitively distinguish between the viewfinder and non-viewfinder areas based on the observed color shades. The relationship between the light transmittance and electrical signals varies depending on the type of electrochromic material, and will not be elaborated upon here.

[0071] In some embodiments, the light transmittance of the lenses of the smart glasses can vary with electrical signal parameters.

[0072] For example, the lenses of smart glasses can be made of electrochromic materials, which can undergo electrochemical oxidation-reduction reactions under the action of an applied electric field, gaining or losing electrons and causing a reversible change in the material's color. For instance, by applying different electric fields to different areas of the lens, different areas of the lens can have different light transmittance.

[0073] In some embodiments, the lenses of the smart glasses include an electrochromic layer made of at least one of an electrochromic material, a liquid crystal dimming material, and an electronic ink material.

[0074] For example, the lenses of smart glasses may include an electrochromic layer. During normal use, the transmittance of the electrochromic layer remains unchanged, ensuring good light transmission and improving the user's visual experience. When acquiring image information through the smart glasses, the transmittance of the lenses is adjusted by the electrochromic layer, resulting in different transmittances in the viewing area and the non-viewing area. The lenses of the smart glasses may also include a display layer, which may be made of optical waveguide material for total internal reflection transmission of the virtual image to be displayed. The electrochromic layer may be made of electrochromic material, but is not limited to this; it may also be made of liquid crystal dimming film, e-ink screen, or other materials whose transmittance changes with electrical signal parameters. This is not limited here.

[0075] For example, the electrochromic layer is disposed on the surface of the display layer, or the electrochromic layer and the display layer can be disposed as an integral part, without limitation.

[0076] Please refer to Figure 4, which is a usage scenario diagram of an image information acquisition method for smart glasses provided in an embodiment of this application.

[0077] As shown in Figure 4, the field of view of the smart glasses includes a framing area and a non-framing area. A first area corresponds to the framing area, and a 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 and second light transmittances can be adjusted on both lenses; this is not limited here. For example, the smart glasses include a first lens and a second lens. Adjusting the light transmittance of the smart glasses lenses based on the framing area information includes: adjusting the light transmittance of the first lens and / or the second lens based on the framing area information, such that the first light transmittance of the first lens in the first area corresponding to the framing area is greater than the second light transmittance of the first lens in the second area corresponding to the non-framing area, and / or the first light transmittance of the second lens in the first area corresponding to the framing area is greater than the second light transmittance of the second lens in the second area corresponding to the non-framing area.

[0078] Step S104: Based on the image information acquisition instruction, acquire the target image information corresponding to the framing area based on the adjusted transmittance.

[0079] For example, the image information acquisition instruction can be used to instruct smart glasses to capture and store images within the field of view, thereby obtaining a target image or an image composed of multiple target images.

[0080] The image information acquisition method for smart glasses provided in the above embodiments involves: acquiring an image framing instruction; determining framing range information based on the image framing instruction, wherein the framing range information indicates the framing area and non-framing area within the field of view of the smart glasses; adjusting the light transmittance of the smart glasses lens based on the framing range information, such that a first light transmittance of the smart glasses lens in a first area corresponding to the framing area is greater than a second light transmittance of the smart glasses lens in a second area corresponding to the non-framing area; and acquiring target image information corresponding to the framing area based on the image information acquisition instruction. Because the smart glasses display the framing area and non-framing area within the field of view based on different light transmittance levels, users can easily and intuitively distinguish the framing range of the smart glasses camera, thereby gaining 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.

[0081] Please refer to Figure 5, which is a schematic diagram of an image information acquisition device for smart glasses according to an embodiment of this application. The image information acquisition device for smart glasses can be configured in a server or terminal to execute the aforementioned image information acquisition method for smart glasses.

[0082] As shown in Figure 5, the image information acquisition device of the smart glasses includes: a first instruction acquisition module 110, a framing range determination module 120, a light transmittance adjustment module 130, and a second instruction acquisition module 140.

[0084] The framing range determination module 120 is used to determine framing range information according to the image framing instruction, wherein the framing range information is used to indicate the framing area and non-framing area within the field of view of the smart glasses.

[0085] The light transmittance adjustment module 130 is used to adjust the light transmittance of the smart glasses lens based on the framing range information, so that the first light transmittance of the smart glasses lens in the first area corresponding to the framing area is greater than the second light transmittance of the smart glasses lens in the second area corresponding to the non-framing area.

[0086] The second instruction acquisition module 140 is used to acquire instructions based on image information and to acquire target image information corresponding to the framing area based on the adjusted transmittance.

[0087] In some embodiments, the framing range determination module 120, in the process of determining the framing range information according to the image framing command including the field of view and imaging depth of field, is used to implement:

[0088] Obtain preset target distance information, which reflects the distance between the corneal vertex and the smart glasses lens;

[0089] Based on the target distance information, the field of view, and the imaging depth, the width and height information of the framing area are determined;

[0090] Based on the width information and the height information, the positions corresponding to the framing area and the non-framing area are determined within the field of view, wherein the positions within the field of view that do not belong to the framing area belong to the non-framing area.

[0091] In some embodiments, the framing range determination module 120, in the process of determining the width and height information of the framing area based on the target distance information, the field of view, and the imaging depth, is used to:

[0092] The camera field of view width and camera field of view height of the smart glasses are calculated based on the field of view angle and the imaging depth.

[0093] Based on the target distance information, the camera's field of view width and camera's field of view height are converted into the width and height information of the framing area.

[0094] In some embodiments, the field-of-view determination module 120, in implementing the field of view including a horizontal field of view and a vertical field of view, and in the process of calculating the camera field of view width and camera field of view height of the smart glasses based on the field of view and the imaging depth, is used to:

[0098] Reduce the second transmittance of the second region based on the framing information; and / or,

[0099] The first transmittance of the first region is increased based on the framing range information.

[0100] It should be noted that those skilled in the art will understand that, for the sake of convenience and brevity, the specific working processes of the above-described apparatus and its modules and units can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.
