The user may set an external open right for social information posted by the user, including setting the same or different open rights for users having all or part of social relationships such as friends relationship with the user and users not having all or part of social relationships. For example, a partial open right may be set to allow users without social relationships to expose dynamic information or partial personal information that they post, and so on.
The terminal can acquire social information associated with the user identifier corresponding to the matched user image, the social information is the social information allowed to be acquired by the open authority corresponding to the user identifier, and the social information is displayed on the frame image in the scanning visible area.
In one embodiment, the frame image acquired in the scanning state can be used as a background image for displaying the related social information, the acquired social information is displayed in a superimposed manner on the background image, the social information is combined with the real scene in the image scanning state, the social information is displayed in an augmented reality manner, the social information of the person can be projected out of the periphery of the face, and the display diversity of the social information is improved.
In one embodiment, step S302 includes: detecting whether the similarity between the continuously generated preset number of frame images is larger than a similarity threshold value, if yes, acquiring one frame image containing a face image in a preset area of a scanning visual area from the continuously generated preset number of frame images.
In one embodiment, frame images may be generated at a default lower frame rate, the currently generated frame images are compared to their previous preset number of frame images, and the similarity between the currently generated frame images and the previous preset number of frame images is detected.
The terminal is further provided with a similarity threshold value, the detected similarity is compared with the similarity threshold value, and if the similarity between the current frame image and the previous preset number of frame images is larger than the similarity threshold value, the current image scanning state is judged to be in a stable state. Selecting one frame image from the current frame image and the previous preset number of frame images, and detecting that the frame image contains a face image in a preset area.
And acquiring one frame image containing the face image in a preset area of the scanning visual area from the preset number of frame images when the similarity is larger than the preset similarity. The stability of image scanning can be improved.
In one embodiment, step S302 includes: detecting whether the offset of a camera of a target object in a scanning visual area is smaller than an offset threshold value within a preset duration, and if so, acquiring a generated frame image containing a face image in a preset area of the scanning visual area from the plurality of frame images within the preset duration.
In one embodiment, the terminal may obtain the offset of the camera detected in real time by a detection device of camera offset data associated with the camera. The offset is used for reflecting real-time variation of the camera in spaces such as front, back, upper, lower, left, right and the like. The detection device may be a gyroscope built into the terminal. And comparing the detected offset of each part between preset time periods with a preset offset threshold value, and judging that the terminal is in a current image scanning state of the terminal and is in a stable state when the detected offset of each part is smaller than the offset threshold value.

When the ratio of the face image in the preset area exceeds the preset proportion and the definition exceeds the preset definition threshold, the face characteristic data of the face image are extracted, so that the quality of the extracted face characteristic data is ensured.
In one embodiment, as shown in fig. 4, another method for presenting social information of a user is provided. The method specifically comprises the following steps:
in step S402, an image scanning portal provided by the social network application enters an image scanning state.
In one embodiment, the terminal may provide a control for opening face scanning to view social information on an interface of the social application, where the control is an image scanning entry that enters an image scanning state. When the clicking operation acted on the control is detected, a scanning instruction can be generated, a camera associated with the terminal is started according to the scanning instruction, an image scanning state is entered from the image scanning entrance, and the real scene in the scanning visible area is scanned. And presenting the scanned live-action in a frame image on a display screen of the terminal.
For example, as shown in FIG. 5, the image scan portal may be presented by being presented on an interface of a social type portal selection of a social application. The personal information display area 510 may display personal information of the user of the social application logged in by the terminal, and the area 520 may provide entries of social types including "say", "photo", "video", "live", "check-in", "dynamic album", "log", and "AR camera", and display in the form of corresponding controls. And entering a viewing interface of the corresponding social type from a corresponding entry by receiving clicking operation of the controls of the social types, and displaying social information of relevant types of friends and/or non-friends of the logged-in user. The AR camera is an image scanning portal provided by the social network application. By receiving a click operation on the "AR camera" control, an image scanning state may be entered from the portal. It should be noted that the various social type entries shown in FIG. 5 are merely one example, and the present embodiment is not limited to this particular social type presentation. Social types may also be increased or decreased based on the embodiment shown in FIG. 5. While "AR camera" is just one of the social type names that one embodiment provides, in other embodiments it may be presented in other forms, such as using a normal camera as an image scanning portal.
Step S404, obtaining a frame image of which the preset area in the scanning visible area contains a face image in an image scanning state.
In one embodiment, the terminal scans the scanning visible area in an image scanning state, generates a frame image in real time according to a preset frame rate, and displays the frame image in a display screen of the terminal. The terminal can perform augmented reality processing on the real scene in the scanning visible area in a presentation form of augmented reality (Augmented Reality, AR), generate a frame image according to the processed real scene, cache the frame image, and present the frame image in a display screen of the terminal.
Specifically, the real scene in the scanned visible area is the real scene containing the face in the preset area presented on the terminal display interface, and the frame image is generated in real time according to the preset frame rate. As shown in fig. 6, in the scanning state, the terminal projects a prompt message for aiming at the scanning of the face image. For example, the projected prompt is "please aim the viewfinder at the face of the friend to be scanned and start scanning". The "viewfinder" is the predetermined area 610 in the scan-visible area. The user may aim the camera at the face 620 to be identified in the live view so that it is presented in the preset area 610 of the presentation interface.
In one embodiment, the extraction of the face feature data of the face image included in the frame image may be performed when the current scanning state is detected to be in a stable state. Wherein, whether the current image scanning state of the terminal is in a stable state can be determined by detecting the similarity between the continuously generated preset number of frame images. Or whether the current image scanning state is in a stable state is judged by detecting the offset of the camera.
Specifically, the user can keep the camera aligned to the face to be recognized for a preset time period, the terminal can detect whether the similarity between the continuously generated frame images with preset number exceeds a preset similarity threshold value within the preset time period, and if so, the current image scanning state is judged to be in a stable state. Or, whether the offset of the camera is smaller than the offset threshold value within the preset time period can be detected, and if yes, the current image scanning state is judged to be in a stable state. When it is determined that the operation is not in the steady state, the routine returns to the step S404 described above. And when the frame image is judged to be in a stable state, extracting face characteristic data of a face image contained in the preset area.
In one embodiment, step S404 includes: detecting whether the similarity between the continuously generated preset number of frame images is larger than a similarity threshold value or not in an image scanning state, and if so, acquiring one frame image containing a face image in a preset area of a scanning visual area from the continuously generated preset number of frame images.
The preset number may be 10, 20, etc., and may be determined according to a frame rate, for example, the number of frame images generated within a preset time period (for example, 1 second, 1.5 seconds, 2 seconds, etc.).
The terminal may calculate a degree of similarity between a currently generated frame image and a buffered preset number of previous generation thereof in an image scanning state. If the calculated similarity between the current frame image and the previous preset number of frame images is larger than the preset similarity threshold value, judging that the current image scanning state is in a stable state. Selecting one frame image from the current frame image and the previous preset number of frame images, and detecting that the frame image contains a face image in a preset area. Specifically, the currently generated frame image may be used as the selected frame image. Or the frame image with the clearest face image contained in the preset area in the generated preset number of frame images can be used as the selected frame image.
In one embodiment, step S404 includes: detecting whether the offset of a camera of a target object in a scanning visible area is smaller than an offset threshold value in an image scanning state, and if so, acquiring a generated frame image containing a face image in a preset area of the scanning visible area from the preset time.
The method can detect the offset of the camera within the preset time period in real time through a gyroscope built in the terminal in the image scanning state, and if the offset is smaller than a preset offset threshold value, the current image scanning state is judged to be in a stable state. And acquiring one of the generated frame images including the face image in the preset area of the scanning visual area from the preset time length.
The preset duration may be a default or custom duration, for example, 1.5 seconds. The currently generated frame image may be taken as the selected frame image. Or the frame image with the clearest face image contained in the preset area can be used as the selected frame image in the generated plurality of frame images.
Step S406, extracting face feature data of a face image contained in the frame image.
In one embodiment, a scanning instruction may be received in an image scanning state, and face feature data of a face image included in a frame image may be extracted according to the scanning instruction.
Specifically, a control for starting a scanning instruction of face recognition scanning can be displayed on a display interface in an image scanning state, when a clicking operation of the control is received, a scanning instruction is generated, and face feature data of a face image contained in a preset area of a generated frame image is extracted from the preset area after the scanning instruction is received. As shown in fig. 6, when a click operation on the "start scanning" control 630 is detected, a scanning instruction is generated, and face feature data of a face image included in the preset area 610 in the frame image is extracted.

If yes, the user identification corresponding to the locally matched user head portrait is obtained. Otherwise, the face feature data can be uploaded to a connected background server of the social application, whether one user head portrait of one user is matched with the face image or not is inquired through the server, and a user identification corresponding to the user head portrait matched on the server is obtained.
Specifically, the matching degree between the face feature data of the face image and the face feature data contained in the user image to be compared can be achieved through comparison. When the face feature data contained in one of the user head portraits is detected for the first time, and the matching degree between the face feature data and the face feature data of the face image exceeds a preset matching degree threshold value, the face feature data and the face feature data are judged to be matched. And obtaining the corresponding user identification according to the corresponding relation between the user head portrait and the user identification. The terminal or the server can also directly store the face characteristic data contained in each user head portrait, so that the face characteristic data of the user head portrait can be directly obtained without repeated extraction from the user head portrait when the matching degree comparison is carried out.
If the matched user head portraits are not found, prompt information of the users which are not found to be matched can be displayed on the scanning interface. For example, a prompt message "do not find a corresponding friend, please rescan" may be projected on the scanned interface.
