Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow chart of a content synchronization method according to an embodiment of the present invention, where this embodiment is applicable to a situation where a user determines a specific page number of a read content in an electronic book and jumps to a corresponding page number according to the read content in the paper book, so as to implement read content synchronization, and the method may be executed by a content synchronization apparatus, where the apparatus may be implemented in a form of software and/or hardware, and the hardware may be an electronic device, and the electronic device may be a mobile terminal or a PC terminal, and the like.
Before introducing the technical solution, a specific application scenario may be exemplarily described. With the popularization of electronic books, users can read not only paper books but also electronic books. Generally, the reading software may be installed on an electronic device, such as a mobile terminal. A large number of electronic books exist in the reading software, and a user can trigger the corresponding electronic books to read. In the actual reading process, the user can adjust the size of the fonts in the electronic book according to actual requirements. Therefore, the corresponding page numbers of the same contents are different between the electronic book and the paper book. The embodiment may be a scheme of determining reading content corresponding to a certain page number of a paper book, determining a target reading page number in an electronic book, and presenting the target reading content of the target reading page number.
As shown in fig. 1, the method of this embodiment includes:
and S110, acquiring a target image and extracting target reading content in the target image.
When the specific page number of the current reading content in the electronic book needs to be determined, an image including the current reading content can be shot based on the camera device, and the image is taken as a target image. Correspondingly, the target image includes the content that the user reads on the paper book currently, so the target reading content is the content that the user reads on the paper book currently.
For example, a user may generally read a paper book, and when the user needs to read the book on the electronic device, in order to continue reading the content of the paper book on the electronic device, the content currently read on the paper book may be obtained, for example, the current reading content of the user on the paper book is captured, so as to obtain a target image. Furthermore, the text information of the target image can be extracted, and the text information is used as the target reading content.
In this embodiment, the extracting the target reading content in the target image includes: determining a line area containing text information in the target image, and identifying the text information in the line area; and generating the target reading content based on the text information in each line area.
In the process of practical application, there may be a situation that the characters of the same text line in the target image are not on the same horizontal line, and at this time, there may be a problem that the specific character content cannot be identified. To avoid this problem, the target image may be preprocessed. The pre-treatment may be: and performing inclination correction on the target image to enable the contents of the same text line to be positioned on the same horizontal line, thereby facilitating subsequent text extraction. After the correction is finished, a line region containing characters can be identified through a character detection algorithm such as MSER or CTPN, and specific contents in the text line are extracted by adopting a character identification algorithm such as CRNN or Seq2Seq to obtain target reading contents.
And S120, determining a target reading page number of the target reading content in the target electronic book by matching the target reading content with the book content of the target electronic book corresponding to the paper book.
It should be noted that the number of words displayed in each line of the paper book is usually fixed, and the user can adjust the size of the font on the electronic book, so that the number of words displayed in each line is different from the number of words displayed in each line of the paper book. That is, the corresponding page numbers of the same content in the electronic book and the paper book are different; furthermore, the user can also adjust the font size of the displayed electronic book, so that when different sizes of fonts are selected for the same content, the corresponding page numbers of the same content in the electronic book are also different.
After the display word size of the electronic book is determined, the specific page number of the target reading content in the electronic book is determined as the target reading page number.
Specifically, after the target reading content in the target image is extracted, matching processing may be performed based on the target reading content and the content in the electronic book corresponding to the paper book, and a specific page number of the target reading content in the electronic book, that is, a target reading page number, may be determined according to a matching processing result.
In the present embodiment, the matching process includes a matching process based on the directory information and/or a matching process based on the content similarity. The matching processing based on the catalog information can be to determine whether the target reading content includes a catalog or not, and if the target reading content includes the catalog, the reading position of the target reading content in the electronic book can be determined according to the catalog information, so that the target reading page number is determined; the content similarity processing may be to determine a similarity between the target reading content and the content displayed by each page number of the electronic book to determine the target reading page number. Or, whether the target reading content includes the directory or not may be determined, if so, the corresponding page number to be read may be determined, and further, if the user marks the corresponding content, the similarity between the target reading content and each page number content may be determined starting from the marked position and the content corresponding to the page number to be read, so as to determine the target reading page number.
S130, jumping the target electronic book from the current reading page to a target reading page corresponding to the target reading page number.
It should be noted that, if the user has previously used the mobile device to read the electronic book, the user may jump to the page number read last time when triggering the electronic book on the same terminal device.
And the page staying in the electronic book after the previous reading of the user is finished is used as the current reading page. The target reading page number is a specific page number of target reading contents in the electronic book.
Specifically, a user can trigger a control of a content synchronization function on the electronic book, and when the button is detected to be triggered, the user can jump from the current reading page number to the target reading page number, so that the technical effect of reading content synchronization is realized.
According to the technical scheme of the embodiment of the invention, the target image comprising the target reading content and the book content of the electronic book are matched, the target reading page number of the target reading content in the electronic book is determined, and the target reading page number is jumped to continue reading the content of the paper book, so that the technical effect of automatically synchronizing the reading content of the paper book and the reading content of the electronic book is realized.
