Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The photographing method according to the embodiment of the present application may be executed by a control device or a terminal (hereinafter referred to as "terminal device"). When the photographing method is executed by the terminal equipment, the execution main body is the terminal equipment.
Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a photographing method provided in an embodiment of the present application, including:
The certificate shooting operation is generally an operation for determining to shoot a certificate. The credential capture operations described above may include, but are not limited to, at least one of: clicking a setting key, sliding the setting key, executing a setting gesture, continuously touching a current interface, sliding on the current interface according to a set operation track, and the like. The setting keys may be hardware keys, such as "volume plus" key, "volume-" key, etc., or software keys, such as [ √ ] control, and [ … ] control, etc. The gesture of setting may be a fist-to-palm gesture, an "O" gesture, a "V" gesture, or the like. The set operation trajectory may include, but is not limited to: straight line segments, arcs, broken lines or curves extending in a preset direction, and the like. The continuous touch generally refers to a continuous touch time period greater than or equal to a preset time period, for example, 5 seconds.
The photographing guide frame is generally a wire frame for guiding a user to present a document image of a document to be photographed in a target area of a photographing interface. The line of the photographing guide frame can be a dotted line, a solid line or other forms of lines. The shape of the photographing guide frame can be various shapes, such as a circle, a rectangle, a hexagon, a cloud and the like. The embodiment does not limit the specific style of the photographing guide frame. The document to be photographed is typically a document to be photographed. The target area is generally defined by the photographing guide frame.
In the present embodiment, the execution main body may detect the certificate photographing operation using a mounted sensor (e.g., a gravity sensor, a distance sensor, a fingerprint sensor, a hall sensor, a GPS position sensor, an accelerator sensor, etc.). And if the certificate shooting operation is detected, presenting a shooting guide frame.
In practical application, a user can execute certificate shooting operation on a shooting interface. In this way, the terminal device for taking pictures, such as a camera, can detect the certificate shooting operation through the sensor installed on the terminal device, and then present the shooting guide frame. The user can present the certificate image of the certificate to be shot in the target area of the shooting interface.
Among other things, the credential type is typically information that indicates the type of credential. The types of documents may include, but are not limited to, identification cards, health cards, driver's licenses, and the like.
Here, the execution main body may extract the document image presented by the target area and identify the document type of the document image using a related art or a future development technology. In practice, in the case of position determination of the photographing guide frame, the execution subject described above may extract the document image of the target area directly from the position of the photographing guide frame. The execution subject can then identify the credential type of the credential indicated by the credential image using machine learning.
And 103, determining the privacy area of the certificate image according to the certificate type obtained by identification and the mapping relation between the certificate type and the position of the privacy area stored in advance.
Here, since a certificate generally has a fixed layout format, and the relative position of the privacy zone of the certificate is generally fixed for the same type of certificate, the mapping relationship between the certificate type and the privacy zone position may be stored in advance for each type of certificate. In this way, the privacy zone can be determined from the certificate image based on the mapping relationship.
The target image is usually a preset image. As an example, the target image may be a mosaic image, a smile image, or the like.
Here, after the privacy area of the certificate image is obtained, the target image may be directly overlaid on the privacy area, so that a new certificate image that protects privacy may be obtained.
According to the method provided by the embodiment, when the certificate is photographed, the type of the photographed certificate image is judged, so that the target image is directly covered at the position of the privacy area of the certificate image based on the certificate type, and the privacy content in the certificate image can be protected from being leaked. The method has the advantages that the certificate image is directly edited during photographing, and the efficiency of editing the certificate image can be improved.
In some optional implementations of the present embodiment, the presenting the photographing guide frame may include:
firstly, the position and the size of the photographing guide frame are determined according to the photographing direction and the interface size ratio of the photographing interface.
Wherein, the above-mentioned direction of shooing can include horizontal screen direction of shooing and vertical screen direction of shooing. The landscape photographing direction generally refers to a direction in which the long side of the screen is placed parallel or nearly parallel to the landscape direction. The portrait photographing direction generally refers to a direction in which the long side of the screen is placed parallel or nearly parallel to the longitudinal direction.
The above-mentioned interface size ratio of the photographing interface generally refers to the length ratio of the long side and the short side of the photographing interface. In practice, the interface size ratio of the camera interface is typically 4:3 or 16: 9.
Here, the execution body may determine an appropriate position and size for the photographing guide frame according to the current photographing direction and the interface size ratio. As an example, when the photographing direction is a landscape photographing direction, the execution main body may determine the centered position as the position of the photographing guide frame. As another example, when the photographing direction is the vertical screen photographing direction, the execution main body may match the size of the long side of the photographing guide frame with the size of the short side of the screen.
Then, the photographing guide frame of the determined size is presented at the determined position of the photographing guide frame.
Here, the execution main body may present the photographing guide frame after determining the position and size of the photographing guide frame. For example, if the position of the photographing guide frame is determined to be L, the size of the photographing guide frame is determined to be m × n, where m is the width of the photographing guide frame and n is the height of the photographing guide frame. At this time, the execution subject in the above may present the photographing guide frame having a size of m × n at the position L. The implementation mode can realize flexible presentation of the photographing guide frame.
In some optional implementations of the present embodiment, the presenting the photographing guide frame may include: firstly, the photographing guide frame is presented on the first display layer, and the photographing interface is presented on the second display layer. The first display layer is then laminated over the second display layer.
The display layer where the photographing guide frame is located above the display layer where the photographing interface is located, and therefore a user can display a certificate image of a certificate to be photographed in a target area of the photographing interface under the guidance of the photographing guide frame.
Optionally, before the step of laminating the first display layer on the second display layer, the method may further include the following steps: and adjusting the transparency of the first display layer.
Here, since the display layer on which the photographing guide frame is located above the display layer on which the photographing interface is located, when the user photographs the certificate to be photographed, the display layer on which the photographing guide frame is located, which is present above the display layer on which the photographing interface is located, may block part of the contents of the photographing interface. Therefore, the realization mode adjusts the transparency of the first display layer, and is beneficial to realizing that a user better photographs the certificate to be photographed.
In some optional implementations of the embodiment, the overlaying the target image on the privacy area of the document image to generate a new document image includes:
the size of the target image is transformed to fit the size of the privacy zone. And overlaying the size-converted target image on a privacy area of the certificate image to generate a new certificate image.
Here, the execution subject may scale the target image based on a size of the privacy area before overlaying the target image on the privacy area of the document image. In particular, the size of the target image may be transformed to fit the size of the privacy zone. Here, the conversion of the size of the target image to be matched with the size of the privacy area may mean that the sizes of the two are the same or that the sizes of the two are close to each other. As an example, if the privacy area is rectangular and the target image is also rectangular, the size of the target image may be transformed to be consistent with the size of the privacy area. The realization mode can realize accurate protection of the privacy content in the certificate.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of a photographing method according to an embodiment of the present application. The photographing method provided by the embodiment may include the following steps:
And step 203, determining the privacy area of the certificate image according to the certificate type obtained by identification and the mapping relation between the certificate type and the position of the privacy area stored in advance.
In the present embodiment, the specific operations of steps 201-204 are substantially the same as the operations of steps 101-104 in the embodiment shown in fig. 1, and are not repeated herein.
And step 205, in response to detecting the editing operation aiming at the target image in the new certificate image, presenting operation guide information for guiding the user operation.
The editing operation is generally an operation for determining to edit a target image in a new certificate image. The editing operation may include, but is not limited to, at least one of: clicking a setting key, sliding the setting key, executing a setting gesture, continuously touching a current interface, sliding on the current interface according to a set operation track, and the like. The setting keys may be hardware keys, such as "volume plus" key, "volume-" key, etc., or software keys, such as [ √ ] control, and [ … ] control, etc. The gesture of setting may be a fist-to-palm gesture, an "O" gesture, a "V" gesture, or the like. The set operation trajectory may include, but is not limited to: straight line segments, arcs, broken lines or curves extending in a preset direction, and the like. The continuous touch generally refers to a continuous touch time period greater than or equal to a preset time period, for example, 5 seconds.
It is to be noted that the execution procedure of the editing operation in the present embodiment is different from the execution procedure of the aforementioned certificate photographing operation. As an example, if the editing operation is a continuous touch operation, the credential capture operation may be a sliding operation from left to right.
The operation guidance information is generally various information for guiding the user operation. As an example, the operation guidance information may be: "the long-press target image can generate two sub-target images". As another example, the operation guidance information may also be: "pressing two sub-target images at the same time can be merged into one target image".
And step 206, in response to detecting the interactive operation of the user based on the operation guide information, executing a processing step corresponding to the interactive operation on the new certificate image.
The interactive operation may be one operation or a series of operations. In practice, the interaction may include, but is not limited to, at least one of: zooming operation, splitting operation, merging operation and dragging operation.
The zoom operation is generally an operation for instructing reduction or enlargement of a target image. As one example, the zoom operation may implement zooming out of the target image at one click of the target image area and zooming in of the target image at two clicks of the target image area. As another example, the zooming operation may be a movement of two fingers touching the target image area in a direction away from each other to enlarge the target image, and a movement of two fingers touching the target image area in a direction close to each other to reduce the target image.
The splitting operation is generally an operation for instructing splitting of a target image. As an example, the splitting operation may be an operation that slides along a trajectory line that intersects the target image, enabling splitting of the target image along the trajectory line that intersects the target image. As another example, the splitting operation may also be an operation of sliding along the closed trajectory line within the target image area, enabling splitting of the target image along the closed trajectory line. It should be noted that the above-mentioned trajectory line penetrating the target image and the above-mentioned closed trajectory line are generally trajectory lines arbitrarily drawn by the user.
The merge operation is generally an operation for instructing to merge a plurality of sub-target images. As an example, the merging operation may be a movement of a plurality of fingers touching the plurality of sub-target image areas in a direction of moving toward each other, so as to merge the plurality of sub-target images.
Among them, the drag operation is generally an operation for instructing to move the target image. As an example, the drag operation may be an operation of continuously touching the target image for a period of time and then moving along the trajectory, so as to drag the target image.
The processing procedure corresponding to the interactive operation is usually a preset processing procedure corresponding to the interactive operation.
Optionally, if the interactive operation includes a splitting operation and a dragging operation, the processing steps corresponding to the interactive operation may be: firstly, a target image is split into a number of sub-target images indicated by the splitting operation, and then all the sub-target images are sequentially moved to the positions indicated by the corresponding dragging operations. For example, the processing step corresponding to the interactive operation may be to split the target image into three sub-target images, and then move the three sub-target images to the position indicated by the dragging operation.
Optionally, if the interactive operation includes a zoom operation, the processing step corresponding to the interactive operation may be: and scaling the target image to the size indicated by the scaling operation.
Here, the execution main body may detect an interactive operation of the user based on the operation guidance information through a sensor installed in the execution main body, and then, may process a new certificate image using a processing step corresponding to the interactive operation.
Here, the execution main body may present a new certificate image after processing. In this way, the user can visually view the processed new document image.
Note that the new document image is an image obtained by overlaying the target image on the original document image, and the new document image may be written as a processed document image for the purpose of description distinction. The processed new certificate image is an image processed by the primary processing certificate image by adopting a processing step, and the processed new certificate image can be recorded as a secondary processing certificate image for distinguishing description.
According to the method provided by the embodiment, if the user is not satisfied with the automatically overlaid target image, the user can manually edit the target image. In this way, the terminal device can present operation guidance information for guiding the user operation based on the editing operation. The user can edit the certificate image rapidly under the guidance of the operation guide information, and the efficiency of editing the certificate image can be improved. Due to the fact that editing can be conducted according to the intention of the user, the efficiency of editing the certificate image is improved, and meanwhile the privacy content is further protected accurately. In addition, when the certificate image is edited, only one editable item, namely the target image, is introduced, and excessive edibles do not need to be introduced, so that the user can conveniently, quickly and accurately edit the certificate image under the condition of not increasing the size of the application package.
In all embodiments of the application, the terminal device may present the photographing guide frame when detecting a certificate photographing operation, so as to guide a user to present a certificate image of a certificate to be photographed in a target area of a photographing interface. The document image presented by the target area is then extracted, and the document type of the document indicated by the document image is identified. And then, determining the privacy area of the certificate image according to the certificate type obtained by identification and the mapping relation between the certificate type and the position of the privacy area, which is stored in advance. Finally, overlaying the target image on the privacy zone of the credential image to generate a new credential image may overlay the target image on the privacy zone of the credential image to generate the new credential image. The terminal equipment can upload the generated new certificate image to the block chain, so that the safety and the fair transparency to the user can be guaranteed. The user equipment may download the data information from the blockchain to verify whether the data information is tampered. The blockchain referred to in this example is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. The block chain (Blockchain), which is essentially a decentralized storage server, is a string of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, which is used for verifying the validity (anti-counterfeiting) of the information and generating a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
