Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be understood that, in various embodiments of the present invention, the sequence numbers of the processes do not mean the execution sequence, and the execution sequence of the processes should be determined by the functions and the internal logic of the processes, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
It should be understood that in the present application, "comprising" and "having" and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be understood that in the present invention, "B corresponding to A" means that B is associated with A, from which B can be determined. Determining B from a does not mean determining B from a alone, but may be determined from a and/or other information. And the matching of A and B means that the similarity of A and B is greater than or equal to a preset threshold value.
As used herein, "if" may be interpreted as "at … …" or "when … …" or "in response to a determination" or "in response to a detection", depending on the context.
It should be understood that, in the present invention, the target picture quitting display refers to a situation that the target picture is closed, switched to a background, switched to display of other pictures or interfaces, and the like, and the target picture is moved out of the current display interface so that the target picture is finished being displayed.
The original direction of the target picture is the display direction inherent to the target picture itself, and is usually determined by the position of a reference line of an acquisition device that acquires the target picture. And when the display device does not perform any rotation processing on the target picture or the current rotation angle is 0, displaying the target picture in the original direction of the target picture.
In the invention, the target picture is rotated by the rotation angle according to the rules of positive anticlockwise rotation and negative clockwise rotation, namely, if the rotation angle is a positive value, the target picture is rotated anticlockwise, and if the rotation angle is a negative value, the target picture is rotated clockwise.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The image display method of this embodiment may be applied to an online service system, and fig. 1 is an application scenario provided in the embodiment of the present invention. As shown in fig. 1, when a client transacts an insurance service, the client needs to log in the online service system of the server 130 at the personal client 110 to fill in personal information, and upload personal identification card scan pieces, physical examination report scan pieces and other related photos. Most of the pictures are collected by clients, and the original direction of the pictures is not modified by professional retouching software although the display direction is adjusted during previewing before uploading. After receiving the pictures uploaded by the client, the online service system of the server 130 first displays the application document and the pictures in the application document to the auditor. The auditor logs in the online service system of the server 130 through the computer 120 responsible for the first process. If the auditor finds that the display direction of the picture is wrong, the display direction of the picture can be adjusted, for example, the picture is manually rotated by 90 degrees relative to the original direction by clicking a rotating button, the online service system records the rotated picture for 1 time of rotating operation with the rotating angle of 90 degrees when the picture is quitted to be displayed, and the online service system automatically determines the correct display direction of the picture according to the recorded historical data when the file is subsequently displayed or the rotated picture is to be displayed on other files such as service contracts, payment notices and the like. The subsequent process service personnel logs in the network service system of the server 130 through the computer 120 responsible for the processes two to N.
For example, if a document scanner is displayed at a 90 ° rotation angle with respect to the original direction 3 times but at a 270 ° rotation angle with respect to the original direction 19 times as recorded in the history data, the online service system defaults to display at a 270 ° rotation angle with respect to the original direction when displaying the document scanner at the 20 th time. In the application scene of the picture display, for a client, the client does not need to perform professional processing on the acquired picture, and the system can display the picture correctly no matter how the display direction of the picture is, so that convenience is brought to the client. For business personnel handling business, the business file is usually in a fixed format, and no matter whether the display of the picture submitted by a client meets the file specification or not, the system can adjust the subsequent display direction according to the historical display.
Fig. 2 is a schematic flowchart of a picture display method according to an embodiment of the present invention. The main body of the method shown in fig. 2 is an electronic device, which may be a personal computer terminal, a client, a server, a business processing system, or the like. Further, the terminal may be a mobile terminal or a fixed terminal. The mobile terminal includes, but is not limited to, a mobile device having an image capturing or receiving function, such as a mobile phone, a Personal Digital Assistant (PDA), a tablet computer, a portable device (e.g., a laptop computer, a pocket computer, or a handheld computer). The fixed terminal includes but is not limited to a fixed device with an image capturing or receiving function, such as an entrance guard, a smart phone, a console, and the like. The embodiment of the present invention does not limit the form of the terminal. The method flow shown in fig. 2 specifically includes the following steps:
s101, if the target picture is determined to be the picture to be displayed, the index of the target picture is obtained.
The index of the target picture corresponds to the current rotation angle of the target picture, and the current rotation angle is determined by historical operation data.
Optionally, the target picture may be determined to be a picture to be displayed when the target picture is inserted, or the target picture is previewed, or a document including the target picture is displayed. The method for obtaining the index of the target picture may be to perform Secure Hash Algorithm (SHA) on the target picture to obtain the unique image feature code of the target picture, and use the unique image feature code as the index of the target picture, or may be to bind and store the indexes of the target picture and the target picture in advance, and obtain the index bound and stored with the target picture while obtaining the target picture.
The index of the target picture may be a unique image feature code obtained through a feature code algorithm operation, or a code given to the target picture according to a preset rule, for example, a serial number including time information. The feature code Algorithm for obtaining the unique image feature code from the target picture may include, but is not limited to, Message Digest Algorithm fifth edition (MD 5 for short), or SHA. The index of the target picture and the current rotation angle of the target picture have a mapping relationship, in other words, the current rotation angle of the target picture can be queried according to the index of the target picture.
The current rotation angle is specifically an angle determined by calculation from historical operating data. The historical operation data of the target picture and the current rotation angle of the target picture correspond to the same index. In one implementation, the historical operation data may be historical rotation angles of the final display direction relative to the original direction of the target picture at each display of the target picture, and the number of operations corresponding to each historical rotation angle. For example: historical rotation angle of 270 degrees corresponds to operation times of 19 times; the historical rotation angle is 90 degrees, and the corresponding operation times are 3 times; the historical rotation angle of 30 degrees corresponds to the operation times of 1 time. In another implementation, the historical operation data may include an operation time, such as a last operation time each time the display is exited, in addition to the historical rotation angle and the number of operations. The implementation manner of determining the current rotation angle from the historical operation data may be to determine the historical rotation angle with the largest operation times as the current rotation angle, or may determine the historical rotation angle corresponding to the last operation time as the current rotation angle.
And S102, acquiring the current rotation angle of the target picture according to the index of the target picture.
Optionally, the index of each picture may correspond to the picture itself, the current rotation angle of the picture, and the historical operation data, and then the query relationship among the picture itself, the current rotation angle of the picture, and the historical operation data may be established through the index.
S103, determining the corrected display direction of the target picture according to the current rotation angle and the original direction of the target picture, and displaying the target picture in the corrected display direction.
Alternatively, one implementation manner of determining the correction direction may be to rotate the target picture relative to the original direction by the current rotation angle, and the obtained direction is used as the correction direction. Fig. 3 is an example of modifying a display direction according to an embodiment of the present invention. As shown in fig. 3, the target picture is a portrait picture, the original direction is displayed head to left and body to right, the current rotation angle is 270 °, and the obtained correction direction is head to head and body to down. The rotation direction of all angles of the invention follows the rule of positive anticlockwise rotation and negative clockwise rotation.
According to the picture display method provided by the embodiment of the invention, before the target picture is displayed, if the target picture is determined to be the picture to be displayed, the index of the target picture is obtained, the index of the target picture corresponds to the current rotation angle of the target picture, and the current rotation angle is the angle determined by the historical operation data, so that the most appropriate current rotation angle is fed back according to the historical operation data; acquiring the current rotation angle of the target picture according to the index of the target picture; and determining the corrected display direction of the target picture according to the current rotation angle and the original direction of the target picture, and displaying the target picture in the corrected display direction. The image content of the target picture does not need to be identified, the calculation process is simple, and the current rotation angle is determined according to the learning of historical operation data, so that the target picture can be displayed in the direction meeting the current requirement.
Optionally, the historical operation data may include: historical rotation angle and the operation times for acquiring the historical rotation angle. On the basis of the embodiment shown in fig. 1, after each time the target picture is displayed, the process of updating the current rotation angle is further included:
firstly, when the target picture is detected to quit displaying, the last rotation angle of the target picture relative to the original direction is obtained. And then updating the historical operation data of the target picture according to the last rotation angle. And finally, determining a new current rotation angle according to the updated historical operation data. For example, the user operates the target picture to rotate it by 90 °, 180 ° and 270 ° in sequence from the original direction, and finally exits from the display to obtain the last determined 270 ° as the last rotation angle. 270 ° is added to the historical operating data of the target picture. As an example of optional historical operation data, the original historical operation data in the target picture includes:
historical rotation angle of 270 degrees corresponds to operation times of 19 times;
the historical rotation angle is 90 degrees, and the corresponding operation times are 3 times;
the historical rotation angle of 30 degrees corresponds to the operation times of 1 time.
Then, in the updated historical operation data, include:
historical rotation angle of 270 degrees corresponds to operation times of 20 times;
the historical rotation angle is 90 degrees, and the corresponding operation times are 3 times;
the historical rotation angle of 30 degrees corresponds to the operation times of 1 time.
Optionally, the specific process of updating the historical operation data of the target picture according to the last rotation angle may be: and judging whether the historical rotation angle identical to the last rotation angle exists in the historical rotation angles corresponding to the target picture.
If it is determined that the target picture has been rotated by the same angle in the historical operation and displayed, 1 is added to the number of operations corresponding to the historical rotation angle having the same last rotation angle to accumulate the number of operations for the existing historical rotation angle, as described in the above example of the historical operation data.
If not, the newly obtained last rotation angle is shown to appear for the first time, the target picture is not rotated and displayed at the same angle in the historical operation, the obtained last rotation angle is used as a new historical rotation angle and is stored in the historical operation data, the operation frequency corresponding to the new historical rotation angle is set to be 1, and the initialized assignment of the operation frequency is carried out on the newly added historical rotation angle.
Alternatively, the specific process of determining the new current rotation angle according to the updated historical operation data may be to determine the current rotation angle with the largest number of operations. For example, the maximum operation times among all the operation times of the updated historical operation data is acquired, and then the historical rotation angle corresponding to the maximum operation times is determined as the new current rotation angle. For another example, the current rotation angle may be determined based on a ratio of the number of operations of each historical rotation angle to all the number of operations. Suppose there are only 4 historical rotation angles, 0 °, 90 °, 180 °, and 270 °, respectively, and the number of operations for the 4 historical rotation angles is Mi(i ∈ (0..3)), where i ∈ (0.), 1, 2, and 3 sequentially indicate that the historical rotation angle is 0 °, 90 °, 180 °, and 270 °. The ratio of the number of operations of 4 historical rotation angles is Ri：
Will maximize RiAnd determining the corresponding historical rotation angle as a new current rotation angle.
Optionally, in order to avoid that the current rotation angle meeting the user requirement cannot be updated in time due to too large accumulation of the original historical rotation angles after the user requirement is changed, after the historical rotation angle corresponding to the maximum operation frequency is determined as the new current rotation angle, whether to be cleared may be further detected. Specifically, the zero clearing may be performed periodically, or may be performed when the maximum number of times of operation is far greater than the number of other times of operation. For example, the total number of all the operation times of the updated historical operation data is acquired, and if the ratio of the maximum operation time to the total number is greater than the zero clearing threshold, the historical rotation angle is cleared and the operation times of acquiring the historical rotation angle are acquired.
Optionally, before obtaining the index of the target picture, a process of setting an index for the target picture is further included:
and when the target picture is received and stored, generating a unique image feature code of the target picture according to the image feature code of the target picture. The unique image feature code obtained by the image feature of the target picture is a feature code with uniqueness, and each picture can only obtain one unique image feature code, so that the index taking the unique image feature code as the target picture has uniqueness. The unique image feature code may be generated by a fifth version of the Message Digest Algorithm (MD 5 for short), or by a series of hash algorithms such as SHA.
After the unique image feature code of the target picture is obtained, judging whether an index identical to the unique image feature code exists or not;
if not, the target picture is a new picture which is not stored, the current rotation angle of the target picture is set to be 0 degree, and the unique image feature code is determined as the index of the target picture and the current rotation angle.
And if so, indicating that the target picture is the stored picture, and determining the index of the target picture by using the index which is the same as the unique image feature code.
Optionally, if it is determined that the target picture is displayed in the document, determining a modified display direction of the target picture according to the current rotation angle and the original direction of the target picture, specifically including a process of further determining the modified display direction according to the layout direction of the document:
firstly, determining the typesetting direction of the document according to the display direction of characters in the document. Fig. 4 is an example of vertically displaying the target picture in the document according to an embodiment of the present invention. Fig. 5 is an example of transversely displaying the target picture in the document according to an embodiment of the present invention. When the text is included in the document, the layout direction of the document is determined according to the display direction of the text. In the example shown in fig. 4, the document layout is a vertical layout. In the example shown in fig. 5, the document layout is a landscape layout. And after the typesetting direction of the manuscript is obtained, acquiring a reference rotation angle from the original direction of the target picture to the typesetting direction. For example, the reference rotation angle is 90 ° in the original direction of the target picture shown in fig. 3 and the document layout direction shown in fig. 5. Then, a correction angle is obtained based on the reference rotation angle and the current rotation angle. For example, if the reference rotation angle is 90 ° and the current rotation angle is 270 °, the correction angle of the target picture obtained from 90 ° +270 ° is 360 °. And finally, determining the display direction of the target picture which is rotated by the correction angle relative to the original direction as the correction display direction. And when the correction angle is 360 degrees, determining the direction of the target picture after rotating 360 degrees relative to the original direction as the correction display direction.
