[0035] 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.

[0036] 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 also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0037] Embodiments of the present application provide an information display method, a head-mounted device, and a computer-readable storage medium.

[0038] 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.

[0039] Please refer to Figure 1 , Figure 1 A flowchart of an information display method provided for an embodiment of the present application. The information display method can be used in a head-mounted device to detect and recognize a human face through a camera component of the head-mounted device, determine first target information corresponding to the human face, and associate the first target information with the human face for display. The head-mounted device can be smart glasses, smart helmets, etc., such as AR glasses, AR helmets, etc.

[0040] like Figure 1 As shown, the information display method includes steps S101 to S103.

[0041] Step S101: Acquire a current face image recognized by the camera assembly of the head mounted device.

[0042] Exemplarily, the head-mounted device may be a smart device that implements a display function through a near-eye display component. In the head-mounted device, a camera component is provided. When a user wears the head-mounted device, the head-mounted device can obtain images of the environment around the user through the camera component. For example, smart glasses can use a camera to capture the real environment observed by the wearer through the lenses. The camera component may be a camera and / or other sensors that can detect human faces. The near-eye display component is a component that allows the user to display relevant information in front of the user's eyes when wearing the head-mounted device. The composition of the near-eye display component can be described in the relevant technology and will not be described in detail in this embodiment.

[0043] Exemplarily, the information display method provided in the embodiment of the present application is used to display information related to a specific face. To achieve this, the head-mounted device first needs to determine whether there is a face image in the wearer's field of view. Therefore, the head-mounted device recognizes the current face image through the camera component. Specifically, the face detection can be performed on the image recognized by the camera component through a face recognition algorithm. The face recognition algorithm can be, for example, a face recognition classifier in OpenCV. It can be understood that the camera component may or may not perform a shooting operation during the process of recognizing a face image, similar to the process of taking a photo, before the shooting command is triggered, the camera component can locate the face within the shooting range, that is, the face image recognized by the camera component in the embodiment of the present application can be a face recognized by the camera component, or a face image captured by the camera component.

[0044] In some implementations, obtaining the current face image recognized by the camera assembly of the head mounted device includes:

[0045] When the camera assembly recognizes a plurality of candidate facial images, obtaining distance information corresponding to each of the candidate facial images, wherein the distance information is used to represent the distance between the location of the candidate facial image and a preset reference location;

[0046] A current face image is determined from each of the candidate face images according to the distance information, wherein the distance between the position of the current face image and the preset reference position is less than a first preset distance threshold.

[0047] For example, in some special scenarios, such as crowded places, the camera component may recognize multiple candidate facial images at the same time. The amount of calculation required to determine whether these candidate facial images have matching first target information is large, which may easily cause a waste of computing resources of the head-mounted device. To avoid this situation, the head-mounted device can filter out the current facial image based on the distance between the location of the candidate facial image and a preset reference location, where the preset reference location can be the location of the camera component or the location of the center point of the head-mounted device display interface.

[0048] Exemplarily, if the preset reference position is the position of the camera assembly, and the camera assembly is taken as an example, since when an object is imaged through the camera lens, there is a proportional relationship between the actual size of the object and the size of its projection on the camera, and this proportional relationship is determined by the focal length of the camera, the distance between the face and the camera can be estimated based on the actual size of the face, the size of the face image in the camera, and the focal length of the imaging as the distance information corresponding to the candidate face image. If the face is far from the camera, there is no need to match the candidate face image with the first target information. Only when the face is close to the camera, it indicates that the user may need to pay attention to the first target information corresponding to this face. At this time, the head-mounted device determines the candidate face image corresponding to the face as the current face image recognized by its camera assembly.

[0049] For example, if the preset reference position is the position of the center point of the head-mounted device display interface, the wearer can move the head to make the candidate face image close to the center point of the display interface. When the candidate face image is close to the center point of the display interface, the head-mounted device uses the candidate face image as the current face image, avoiding the head-mounted device from performing information matching operations on a large number of faces in the field of view, thereby reducing the power consumption of the head-mounted device.

[0050] Step S102: when it is detected that the current facial image is a target facial image, first target information matching the target facial image is obtained.

[0051] Exemplarily, after the head mounted device determines that the current face image exists in the wearer's field of view through step S101, it can perform information matching on the current face image to determine whether there is corresponding first target information for the current face image. Specifically, the facial feature information of the current face image can be matched in a preset database. If there is a preset face matching the facial feature information in the database, the current face image is determined as the target face image, and the information associated with the target face image is obtained as the first target information corresponding to the target face image.

[0052] The information corresponding to the target facial image is stored in the head-mounted device in advance in association with the facial information, and is the relevant information output by the user corresponding to the target facial image collected when the head-mounted device recognizes the target facial image through the camera component during the historical period. Exemplarily, if the wearer of the head-mounted device is user A, and if user A talks with user B while wearing the head-mounted device during a certain historical period, the head-mounted device can extract the chat information during the conversation between user A and user B, and store the relevant information of the chat information in association with the facial image of user B in the head-mounted device, and the relevant information of the chat information is the first target information corresponding to the facial image of user B.

[0053] In some implementations, the acquiring first target information matching the target facial image includes:

[0054] Acquire second target information stored corresponding to the target face image;

[0055] The first target information is determined according to the second target information, wherein an amount of information of the first target information is less than or equal to an amount of information of the second target information.

[0056] In one embodiment, the method for generating the second target information can refer to the following embodiments and will not be repeated here. After the head mounted device obtains the second target information, the head mounted device can directly store the second target information, or extract key information from the second target information and store the key information in the second target information as the first target information, wherein the key information is keywords such as person, time, and location in the second target information. In one embodiment, the head mounted device can also directly store the first target information and the second target information.

[0057] When the head-mounted device needs to display the first target information that matches the target facial image, that is, when the head-mounted device needs to display the first target information associated with the target facial image, the head-mounted device can obtain the second target information, and use the key information in the second target information as the first target information. At this time, the amount of information of the first target information is less than the amount of information of the second target information; the head-mounted device can also directly display the second target information as the first target information. At this time, the amount of information of the first target information is equal to the amount of information of the second target information.

[0058] It can be understood that when the amount of information of the first target information is less than the amount of information of the second target information, the amount of information that the head-mounted device needs to display is reduced, thereby reducing the occlusion of the wearer's field of view by the first target information, and also reducing the amount of information that the wearer needs to receive, thereby improving the efficiency of information reception.

[0059] Exemplarily, the second target information and the first target information may be in different formats. For example, the second target information may be an audio file obtained by recording the conversation between the wearer and the user corresponding to the target face image. When the first target information needs to be displayed, the audio file is subjected to text recognition and text extraction to obtain key information corresponding to the second target information as the first target information. Of course, it is not limited to this. The first target information may also include the storage time and storage location of the second target information to prompt the wearer the time and location of the conversation.

[0060] In some implementations, step S102 includes:

[0061] When detecting that the current facial image is a target facial image, determining the number of the target facial images;

[0062] If there are at least two target face images, first target information matching the target face image corresponding to the minimum target distance is obtained, wherein the target distance is the distance between the position of the target face image and the preset target position.

[0063] For example, in some special scenarios, such as crowded places, the camera component of the head-mounted device may recognize multiple facial images at the same time, that is, the head-mounted device detects multiple current facial images, and there may be multiple target facial images at this time. If the first target information corresponding to all target facial images is displayed, it may cause the display interface to be unable to display all the first target information, and may also affect the display of other content in the display interface. And when the head-mounted device is a device with AR display function, displaying too much first target information will block the line of sight of the wearer wearing the head-mounted device. Therefore, in order to solve the above problem, the head-mounted device in the embodiment of the present disclosure determines the number of target facial images when detecting that the current facial image is a target facial image; if there are at least two target facial images, the first target information matching the target facial image corresponding to the minimum target distance is obtained, wherein the target distance is the distance between the position of the target facial image and the preset target position, and the preset target position may be the same as the preset reference position or different from the preset reference position. For example, when the preset target position is the center point of the display interface, the first target information is the information corresponding to the target face image closest to the center point of the display interface.

[0064] In some embodiments, the method further comprises:

[0065] When the duration for which the camera component fails to recognize a facial image is greater than a preset duration, the camera component is turned off.

[0066] For example, the wearer can activate the camera component in the head-mounted device through an icon, button or sensor (such as an infrared sensor, an inertial measurement unit, a Bluetooth module, etc.) to recognize the face through the camera component.

[0067] For example, if the camera component of the head-mounted device is started and no face image is detected within the preset time, that is, the time for which the camera component does not recognize the face image is longer than the preset time, it means that the wearer may have triggered the function by mistake, or the user no longer needs the function due to changes in circumstances. In order to avoid heating and power consumption caused by long-term operation of the camera component, the head-mounted device actively triggers the shutdown command, and the camera component is shut down through the shutdown command. The preset time can be set according to the actual situation, for example, it can be 30 seconds, of course, it is not limited to this, and is not limited here.

[0068] This embodiment turns off the camera component of the head-mounted device when the camera component of the head-mounted device fails to recognize a facial image for longer than a preset time, thereby avoiding the camera component from being in operation when not needed, thereby reducing the power consumption of the head-mounted device and improving the battery life of the head-mounted device.

[0069] In some embodiments, the method further comprises:

[0070] In the case where it is identified that the current facial image does not belong to the target facial image, second target information corresponding to the current facial image is obtained and the second target information is stored.

[0071] Exemplarily, if the current facial image does not belong to the target facial image, it indicates that the camera component of the head-mounted device has not recognized the current facial image before, or that the current facial image has been recognized before, but the head-mounted device does not store information associated with the face. At this time, the head-mounted device obtains the second target information corresponding to the current facial image, and stores the second target information in association with the current facial image.

[0072] Exemplarily, for the current face image belonging to the target face image, the user may also update the corresponding second target information through a specific operation, thereby improving the real-time performance of the second target information.

[0073] In some implementations, the step of acquiring second target information corresponding to the current facial image when it is recognized that the current facial image does not belong to the target facial image includes at least one of the following:

[0074] Acquire voice information input for the current face image, and store the voice information as second target information corresponding to the current face image; or

[0075] Acquire text information input for the current face image, and store the text information as second target information corresponding to the current face image.

[0076] Exemplarily, the second target information may be an audio file corresponding to the voice information, such as the head mounted device recording the voice information of the conversation between the wearer and the user corresponding to the current face image, and storing the voice information as the second target information in association with the current face image, thereby improving the convenience of inputting the second target information. At this time, the second target information includes at least the voice information of the user corresponding to the current face image, and may also include the voice information of the wearer. In another embodiment, after the head mounted device obtains the voice information, the head mounted device converts the voice information into text information, and stores the text information as the second target information in association with the current face image.

[0077] Exemplarily, the second target information can also be input via text. The wearer can input the conversation content with the user corresponding to the current facial image into the head-mounted device in the form of text. When the head-mounted device receives the text information input by the wearer, it uses the text information as the second target information corresponding to the current facial image, and stores the second target information in association with the current facial image.

[0078] This embodiment obtains voice information or text information corresponding to the current face image as the second target information and stores it in association with the current face image, thereby providing multiple ways to obtain the second target information and improving the convenience of obtaining the second target information.

[0079] Step S103: associate the first target information with the target face image and display them on a display interface of the head mounted device.

[0080] After the head mounted device acquires the first target information, the head mounted device associates the first target information with the target face image for display.

[0081] This application obtains the current face image recognized by the camera component of the head-mounted device; when the current face image is detected as a target face image, obtains the first target information that matches the target face image; and displays the first target information and the target face image in association with each other in the display interface of the head-mounted device. The face is detected and recognized by the camera component of the head-mounted device, the first target information corresponding to the face is determined, and the first target information is displayed in association with the face. This enables the wearer to observe a specific face while wearing the head-mounted device, and the information pre-stored for the face is displayed in correspondence with the face, so that the wearer can obtain information related to the face, which reduces the wearer's memory in social, work and other scenarios, allowing the wearer to focus on the conversation occurring in the current environment, thereby improving the intelligence of the information display of the head-mounted device.

[0082] In some implementations, displaying the first target information and the target face image in association with each other on a display interface of the head mounted device includes:

[0083] Displaying the first target information at a position where the distance between the display interface and the target face image is less than a preset distance threshold;

[0084] Alternatively, the first target information is displayed in a first preset area of ​​the display interface, and the first target information is associated with the target facial image through a guide mark.

[0085] When displaying the first target information, the head-mounted device may display the first target information at a position that is less than a preset distance threshold from the position of the target facial image. Exemplarily, any position of a facial image may be used as the position of the target facial image. This embodiment does not limit the position of the target facial image, and the user may set it according to specific needs. During the movement of the target facial image, the text box used to display the first target information also moves accordingly. That is, during the movement of the user corresponding to the target facial image, the display position of the first target information in the display interface of the head-mounted device will also move with the movement of the user corresponding to the target facial image, thereby allowing the wearer to observe the first target information at a position close to the target facial image, and the relationship between the first target information and the target facial image is more intuitive. Figure 2 As shown, the first target information is displayed above the target face image and is relatively close to the target face image. This embodiment does not impose any restrictions on the size of the preset distance threshold.

[0086] In one embodiment, the first target information may also be displayed in a first preset area of ​​the display interface corresponding to the near-eye display component. The first preset area is an area pre-set in the display interface of the head-mounted device. For example, the first preset area may be a specific area in the display interface, such as Figure 3 As shown, the first preset area can be the lower right corner area of ​​the display interface. After the head mounted device determines the first target information, the head mounted device displays the first target information in the first preset area of ​​the display interface, and associates the first target information with the target face image through a guide mark, wherein the guide mark can include an arrow or a guide line. It can be understood that Figure 2 , 3 The current face image in includes face A and face B, wherein face A does not belong to the target face image, and face B belongs to the target face image.

[0087] This embodiment provides a display method for associating multiple first target information with target facial images, so that when there are multiple faces in the display interface of the head-mounted device, it is convenient for the wearer to quickly identify which face the first target information belongs to, thereby improving the recognizability of the first target information.

[0088] In some implementations, displaying the first target information and the target face image in association with each other on a display interface of the head mounted device includes:

[0089] When the target facial image is located in a second preset area of ​​the display interface, the first target information and the target facial image are associated and displayed in the display interface.

[0090] The camera component of the head-mounted device may recognize multiple current facial images, and there may be multiple target facial images in the multiple current facial images. However, if the first target information corresponding to the multiple target facial images is displayed in the display interface of the head-mounted device, it will block the field of view of the wearer of the head-mounted device, and may also block other content displayed on the display interface of the head-mounted device. In order to solve the above problems, the head-mounted device in this embodiment will only associate the first target information with the target facial image and display it in the display interface when the target facial image is located in the second preset area of ​​its display interface. Among them, the second preset area can be the central area of ​​the display interface. Exemplarily, the center point of the display interface can be used as a reference, and the area within the preset range of the center point is the second preset area of ​​the display interface. This embodiment does not limit the shape and size of the second preset area. For example, the second preset area can be a rectangle or a circle.

[0091] This embodiment displays the first target information corresponding to the target facial image only when the target facial image falls within the second preset area of ​​the head-mounted device display interface, thereby avoiding displaying the first target information corresponding to each target facial image and avoiding blocking the line of sight of the wearer of the head-mounted device due to the display of the first target information.

[0092] See also Figure 4 , Figure 4 It is a schematic diagram of an information display device provided in one embodiment of the present application. The information display device can be configured in a head-mounted device to execute the aforementioned information display method.

[0093] like Figure 3 As shown, the information display device includes: a face recognition module 110, an information acquisition module 120, and an information display module 130.

[0096] The information display module 130 associates the first target information with the target face image and displays it in a display interface of the head mounted device.
