BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 is a flow chart of a method for processing book information in an embodiment of the present invention;

[0041] Figure 2 It is a schematic diagram of the structure of a book information processing device in an embodiment of the present invention. DETAILED DESCRIPTION

[0042] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a book information processing method, comprising the following steps:

[0044] Step 101, obtaining barcode data and cover data of a paper book;

[0045] Step 102, obtaining first characteristic data of the paper book according to the barcode data;

[0046] Step 103, matching the first characteristic data of the paper book with a plurality of pre-stored codes to obtain a matching result;

[0047] Step 104: Obtain a target electronic book corresponding to the paper book according to the matching result and the cover data.

[0048] The book information processing method proposed in the embodiment of the present invention first obtains the barcode data and cover data of the paper book, then obtains the first feature data of the paper book through the obtained barcode data of the paper book, and then matches the first feature data of the paper book with multiple pre-stored codes, and obtains the target electronic book corresponding to the paper book based on the matching results and the cover data, thereby improving the accuracy of searching for electronic book resources corresponding to the paper book.

[0049] In an optional embodiment of the present invention, the obtained barcode data of the paper book and the cover data of the paper book can be images, such as images of the barcode of the paper book and the cover of the paper book captured by an image acquisition device (such as a mobile phone, a camera, etc.). It should be noted that although the barcode data is used as an example in this embodiment, it should be understood that it is not limited to a barcode, and can also be a QR code or other code that can identify the book number of the paper book (such as the International Standard Book Number ISBN code).

[0050] In an optional embodiment of the present invention, step 102 includes:

[0051] Step 1021, preprocessing the barcode data to obtain preprocessed barcode data;

[0052] Specifically, if the barcode data is image data, the image data needs to be preprocessed such as filtering and smoothing. The image data can be filtered first to eliminate noise, reduce image details and improve image quality; then the image data can be smoothed by using a smoother or convolution kernel to eliminate noise and jagged effects (the image edges are not smooth and appear jagged).

[0053] Step 1022, correcting the preprocessed barcode data to obtain standard barcode data;

[0054] Specifically, the barcode in the image can be located first to obtain the position and length, width and other size information of the barcode in the image, and then the image rotation algorithm can be used to rotate the barcode to the correct direction according to the tilt angle of the barcode, so that it is aligned with the horizontal or vertical direction. The specific method is: use the contour detection algorithm to find the contour of the barcode in the image, and find the largest contour representing the barcode from the detected contours; use the minimum area enclosing rectangle algorithm (or similar algorithm) to find the enclosing rectangle of the barcode; calculate the tilt angle of the enclosing rectangle, that is, the angle between the barcode and the horizontal direction; according to the calculated tilt angle (that is, the angle between the barcode and the horizontal direction), use the image rotation algorithm to rotate the barcode to the correct direction so that it is aligned with the horizontal or vertical direction. If the barcode image is distorted (such as perspective distortion), image processing techniques such as affine transformation and perspective transformation can be used to correct the distortion of the image. Correcting the pre-processed barcode data can improve the processing efficiency and the accuracy of subsequent interpretation results.

[0055] Step 1023: Decode the standard barcode data to obtain first characteristic data of the paper book.

[0056] Specifically, you can use existing open source libraries or commercial libraries that support barcode decoding, such as ZXing (barcode image processing library), LEADTOOLSSDK (image processing development toolkit), etc., input the standard barcode data into one of the decoding libraries, call the decoding function of the decoding library, decode the standard barcode data, and extract the book number (ISBN code) from the decoding result as the first feature data of the paper book.

[0057] In an optional embodiment of the present invention, step 103 includes:

[0058] The first characteristic data of the paper book is matched according to a plurality of pre-stored codes. If there is a pre-stored code identical to the first characteristic data of the paper book, the matching result is the same pre-stored code; otherwise, the matching result is empty.

[0059] Specifically, a preset e-book database (which can be a database, a platform or a website, etc., as long as it can realize the function of storing e-book resources) stores a large number of e-book resources and codes corresponding to e-books (pre-stored codes). Generally, one e-book uniquely corresponds to one pre-stored code. Therefore, you can search in the preset e-book database according to the first characteristic data of the paper book (i.e., the ISBN code). If you can find a pre-stored code that is consistent with it, it means that there may be an e-book corresponding to the paper book in the preset e-book database. Therefore, the matching result at this time is the pre-stored code that is consistent with the first characteristic data of the paper book. If the pre-stored code that is consistent with the first characteristic data of the paper book cannot be found in the preset e-book database, it means that there is no e-book corresponding to the paper book in the preset e-book database. At this time, the matching result is empty.

[0060] In an optional embodiment of the present invention, step 104 includes:

[0061] Step 1041, when the matching result is the same pre-stored code, obtaining a target electronic book corresponding to the paper book according to the same pre-stored code;

[0062] Specifically, the corresponding electronic book may be retrieved from a preset electronic book database according to a pre-stored code consistent with the first characteristic data of the paper book, and provided to the user as a target electronic book corresponding to the paper book.

[0063] Step 1042: when the matching result is empty, obtain a target electronic book corresponding to the paper book according to the cover data.

[0064] Specifically, when the matching result is empty, it means that the preset e-book database may not contain the e-book corresponding to the paper book, or the pre-stored code of the corresponding e-book in the preset e-book database may be inconsistent with the code of the paper book. Therefore, it is necessary to further search and confirm in the preset e-book database through the cover data.

[0065] In an optional embodiment of the present invention, step 1041 includes:

[0066] Step 10411, retrieve corresponding e-book data from a preset e-book database according to the same pre-stored code;

[0067] Specifically, the corresponding e-book and its related information, such as author, publisher, publication date, etc., are retrieved from a preset e-book database according to the same pre-stored code. The e-book data includes the e-book and the author, publisher, publication date, etc.

[0068] Step 10412, verifying the electronic book data to obtain a verification result;

[0069] Specifically, the author, publisher, publication date and other information in the electronic book data can be compared with the author, publisher, publication date and other information in the cover data. If each piece of information is consistent with each piece of information in the cover data, the verification result can include: consistent author, consistent publisher, consistent publication date, etc. If there is one inconsistency, the verification result can include inconsistent information, such as at least one of inconsistent author, inconsistent publisher, inconsistent publication date, etc.

[0070] It should be noted that the method of verifying the electronic book data is not limited to the above method, and a certain section of the content in the electronic book data can also be extracted and compared with the content extracted from the paper book. If they are consistent, the verification result is that the content is consistent. This application is only for example.

[0071] Step 10413: When the verification result meets the preset qualification condition, the electronic book data is determined as a target electronic book corresponding to the paper book.

[0072] Specifically, the preset qualification conditions may include: consistent author, consistent publisher, consistent publication date, etc. When the verification result matches the preset qualification conditions, it means that the obtained e-book is the electronic resource corresponding to the paper book. At this time, the e-book can be confirmed as the target e-book corresponding to the paper book and provided to the user. If the verification result does not match the preset qualification conditions, that is, the verification result is at least one of the following: the author of the e-book does not match the author of the paper book, the publisher of the e-book does not match the publisher of the paper book, and the publisher of the e-book does not match the publisher of the paper book, it means that the e-book is not the e-book corresponding to the paper book. At this time, the preset information (such as "no e-book corresponding to the paper book was found") can be provided to the user to inform the user of the search result.

[0073] In an optional embodiment of the present invention, step 1042 includes:

[0074] Step 10421, identifying the cover data to obtain second characteristic data of the paper book;

[0075] Specifically, information such as the author, publisher, and publication date of a paper book can be identified from the cover data, and this information is used as the second characteristic data of the paper book for subsequent search of the corresponding e-book.

[0076] Step 10422, determining keywords according to the second characteristic data of the paper book;

[0077] Specifically, the second characteristic data of the paper book can be extracted according to the preset keywords or preset types or preset formats, and the words or numbers consistent with the preset keywords can be extracted as keywords. If the type of the preset keyword is digital, the digital data in the second characteristic data of the paper book is extracted as the keyword; if the preset keyword is "Author: XXX", "Author: A" in the second characteristic data of the paper book is extracted as the keyword. Here, there can be multiple preset keywords or preset types or preset formats, and there can also be multiple determined keywords, which facilitates the subsequent accurate retrieval of the corresponding e-book data from the preset e-book database and improves the accuracy.

[0078] Step 10423, retrieve corresponding e-book data from a preset e-book database according to the keyword;

[0079] Specifically, e-book data consistent with the keywords are retrieved from the preset e-book database. For example, if the keywords are "April 5, 2020", "Author: A", "Publisher: B Publisher", etc., the e-book data that matches "April 5, 2020", "Author: A", "Publisher: B Publisher" in the preset e-book database will be retrieved for subsequent verification.

[0080] Step 10424, verifying the electronic book data to obtain a verification result;

[0081] Specifically, the author, publisher, publication date and other information in the electronic book data can be compared with the author, publisher, publication date and other information in the cover data. If each piece of information is consistent with each piece of information in the cover data, the verification result can include: consistent author, consistent publisher, consistent publication date, etc. If there is one inconsistency, the verification result can include inconsistent information, such as at least one of inconsistent author, inconsistent publisher, inconsistent publication date, etc.

[0082] It should be noted that the method of verifying the electronic book data is not limited to the above method, and a certain section of the content in the electronic book data can also be extracted and compared with the content extracted from the paper book. If they are consistent, the verification result is that the content is consistent. This application is only for example.

[0083] Step 10425: When the verification result meets the preset qualification condition, the electronic book data is determined as a target electronic book corresponding to the paper book.

[0084] Specifically, the preset qualification conditions may include: consistent author, consistent publisher, consistent publication date, etc. When the verification result matches the preset qualification conditions, it means that the obtained e-book is the electronic resource corresponding to the paper book. At this time, the e-book can be confirmed as the target e-book corresponding to the paper book and provided to the user. If the verification result does not match the preset qualification conditions, that is, the verification result is at least one of the following: the author of the e-book does not match the author of the paper book, the publisher of the e-book does not match the publisher of the paper book, and the publisher of the e-book does not match the publisher of the paper book, it means that the e-book is not the e-book corresponding to the paper book. At this time, the preset information (such as "no e-book corresponding to the paper book was found") can be provided to the user to inform the user of the search result.

[0085] In an optional embodiment of the present invention, step 10421 includes:

[0086] Step 104211, adjusting the cover data to obtain adjusted cover data;

[0087] Specifically, the cover data may be a collected cover image of a paper book, and the method for adjusting the cover image may be at least one of the following:

[0088] By enhancing the contrast and brightness of the cover image, the text in the cover image is made clearer, which is convenient for subsequent feature extraction and recognition; the cover image is converted into a black and white binary image, that is, the pixels in the cover image are only black and white, which helps to simplify the subsequent processing process; remove noise in the cover image, such as spots, scratches, etc., to improve the quality of the cover image; correct the tilted cover image to keep the text horizontal and avoid errors in subsequent recognition.

[0089] Step 104212, extracting features from the adjusted cover data according to a preset extraction method to obtain feature information;

[0090] Specifically, by extracting features from the adjusted cover data, relevant information about the paper book in the cover, such as the author, publisher, publication date, etc., is obtained for subsequent recognition. Here, the feature information can be an image, such as an image with the author, an image with the publisher, an image with the publication date, etc., and the type or format of the feature information can be selected according to the recognition method used later.

[0091] The default extraction method can be any of the following:

[0092] Structure-based feature extraction: By analyzing the structural features of text / numbers, such as strokes, radicals, etc., the features of text / numbers in the cover data are extracted. This method is suitable for identifying text / numbers with clear and standardized structures.

[0093] Feature extraction based on statistics: The features of text / numbers are extracted by counting the pixel distribution, grayscale value and other features of the text / numbers. This method is suitable for identifying complex and changeable text / numbers.

[0094] Step 104213: Identify the characteristic information according to a preset identification method to obtain second characteristic data of the paper book.

[0095] Specifically, the identification of the characteristic information mainly identifies the text or numbers in the characteristic information as the second characteristic data of the paper book, so as to facilitate the subsequent rapid and accurate retrieval of the corresponding electronic book data from the preset electronic book database according to the second characteristic data of the paper book.

[0096] The preset identification method can be any of the following:

[0097] (1) Preset recognition method of template matching

[0098] This method is to compare the extracted text features (ie, feature information) with the pre-stored character templates one by one, find the most similar character template, and thus recognize the text / number. This recognition method is simple and intuitive.

[0099] (2) Preset recognition method using preset recognition model

[0100] First, collect multiple characters or digital features extracted from the image as input, and the corresponding character or digital labels as output, so as to obtain a training data set, and divide the training data set into a training set and a validation set. Then set the initial parameters of the preset network model, such as the initial parameters include: the initial learning rate is 0.001 or 0.01, the batch size (the number of training data processed by the preset network model each time) is 32 or 64 or 128 or 256, the number of iterations is 50 or 100, etc. According to the preset network model used, set the parameters specifically, such as the initial parameters also include weights and bias items. Then use the training set to train the preset network model with various parameters set, and adjust the parameters of the preset network model so that the output of the preset network model is close to the true label.

[0101] The method of adjusting the parameters of the preset network model is as follows:

[0102] Input the training set into the input layer of the preset network model; weight and sum the output of the input layer through the activation function to generate the output of at least one processing layer; weight and sum the output of the last processing layer again, and generate the final output through the activation function; use the loss function Calculate the error between the predicted value output by the preset network model and the true label; calculate the partial derivative of the loss function with respect to the final output to obtain the gradient of the output layer; use the chain rule to propagate the gradient of the output layer backward to at least one processing layer, and calculate the gradient of each processing layer. This step is also repeated in each processing layer of the preset network model until the input layer is reached; based on the gradient of each processing layer, calculate the gradient of all parameters in the preset network model, including weights and bias terms. Using the formula: The adjusted parameters are obtained. Among them, the learning rate is a preset hyperparameter that controls the step size of each parameter update. According to the change of the loss function and the performance on the validation set, the learning rate, batch size and other parameters are adjusted, and appropriate stop conditions (such as the number of iterations, loss threshold, etc.) are set to end the training process. According to the final adjusted parameters, the preset recognition model is obtained.

[0103] Among them, L is the loss function, N is the total number of samples in the training set, C is the total number of corresponding character or digital labels, and y i,c is the value of the cth category in the true label of the ith sample (0 or 1), is the value of the cth category in the predicted value of the i-th sample. t+1 is the parameter at the t+1th iteration, θ t is the parameter at the tth iteration, η is the learning rate, is the gradient of the loss function with respect to the parameters, x i is a randomly selected sample, y i are the labels of randomly selected samples.

[0104] The preset recognition model obtains the second feature data of the paper book according to the input feature information. The specific process includes, that is, step 104213 includes the following steps:

[0105] Step 1042131, inputting the feature information into the input layer of the preset recognition model to obtain a first output result;

[0106] Here, the input layer mainly converts the feature information into a format or type that can be recognized and processed by the preset recognition model. If the feature information is an image with an author, publisher, or publication date, the input layer can be The feature information is processed to obtain a first output result, where N is the first output result, W is the feature information, F is the size of the filter, P is the padding size, that is, the number of layers of zeros filled on the boundary of the feature information, which is used to control the size of the first output result, and S is the step size, that is, the distance the filter slides on the input feature information.

[0107] Take a specific example to illustrate, assuming that the feature information is an image with the author, the length and width are both 227, there are 3 color channels (RGB), the length and width of the filter are both 11, the step size is 4, and the padding size is 0. Then, according to the above formula, the size of the first output result can be calculated as: N = (227-11 + 2 × 0) / 4 + 1 = 55, that is, the length and width of the first output result are both 55.

[0108] Step 1042132, inputting the first output result into at least one processing layer of a preset recognition model to obtain a second output result;

[0109] It should be noted that the preset recognition model may include multiple processing layers, and the first output result is sequentially input into the multiple ordered processing layers for processing. The processing process of the processing layer on the first output result includes:

[0110] Use multiple filters to perform local connection and feature extraction on the first output result. Each filter slides on the first output result, calculates the dot product between the filter and the local area of ​​the first output result, and generates a feature map;

[0111] Downsample the feature map to reduce the dimension and computational complexity of the data while retaining important feature information as features to be processed;

[0112] All the features to be processed are integrated together to obtain a vector of a fixed size as the second output result. The second output result includes all the important features extracted from the feature information.

[0113] Step 1042133, input the second output result into the output layer of the preset recognition model to obtain the second feature data of the paper book.

[0114] Specifically, by calculating the dot product of the input second output result and the weight vector of each neuron in the output layer, and adding the bias term, we get the score or probability corresponding to the category, and then use the softmax function The scores are converted into probability distributions. Therefore, for character or number recognition, the prediction result of the preset recognition model is usually a probability distribution, which indicates the possibility of each character or number appearing.

[0115] Among them, y i is the value of the ith element in the second output after the softmax function, that is, the probability prediction of the ith category, x i is the i-th element in the second output result, is the index value of the i-th element in the second output result, is the sum of the index values ​​of all elements in the second output result.

[0116] A specific embodiment of the book information processing method proposed in the embodiment of the present invention is:

[0117] Step 111, obtaining paper book data.

[0118] The barcode image and the cover image of the paper book are collected by an image collection device (such as a mobile phone, a camera, etc.) as the barcode data and the cover data of the paper book respectively.

[0119] Step 112: first characteristic data of the paper book.

[0120] The barcode image is pre-processed by filtering, smoothing, etc., and then corrected. After that, it is interpreted to obtain the ISBN code of the paper book, that is, the first characteristic data of the paper book.

[0121] Step 113: Match the first characteristic data of the paper book with a plurality of pre-stored codes.

[0122] The pre-stored code that is consistent with the ISBN code of the paper book is searched from the e-book resources stored in the preset e-book database. If found, the matching result is the same pre-stored code; otherwise, the matching result is empty.

[0123] Here, the preset e-book database is a database containing e-book resource information, including cover information of each e-book (such as author, publisher and publication date, etc.). For example, the cover size of each e-book is set to 300x400 pixels for easy storage.

[0124] Step 114, determining the target electronic book.

[0125] First, if the matching result is the same pre-stored code, the e-book corresponding to the pre-stored code is directly retrieved from the preset e-book database; if the matching result is empty, the author, publisher, publication date and other information of the paper book are identified from the cover data as the second characteristic data of the paper book, and the e-book consistent with the second characteristic data of the paper book is searched from the preset e-book database. After the e-book is found, it needs to be verified according to the author, publisher, publication date, chapter / paragraph content and other information. If the verification is passed, the found e-book is determined to be the target e-book.

[0126] Here, if no e-book consistent with the second characteristic data of the paper book can be found in the preset e-book database, the e-book with the highest similarity can be selected as the target e-book based on the similarity between the cover of the e-book in the preset e-book database and the second characteristic data of the paper book.

[0127] Afterwards, the target e-book may be displayed in a preset display mode (such as displaying only the cover of the e-book), or the target e-book may be sent to the client for the user to view.

[0128] The book information processing method proposed in the embodiment of the present invention combines cover character recognition and image similarity matching to improve the accuracy of book recognition, and supports book cover recognition and back ISBN barcode recognition at the same time, adapting to different situations.

[0129] The paper book identifier includes a barcode, which includes the ISBN code of the paper book. The barcode corresponds to the paper book and is unique. The e-book corresponding to the paper book is searched through the ISBN code. Since the same book title corresponds to different paper books and has different ISBN numbers, when the corresponding e-book cannot be found through the ISBN number, the information contained in the book cover can be extracted, including text information and image element information. The valid text content is identified based on the extracted information, and the e-book is matched in the preset e-book database.

[0130] The book information processing method proposed in the embodiment of the present invention obtains the barcode data and cover data of the paper book by scanning the cover and barcode of the paper book, and preferentially matches the electronic book according to the ISBN number and book cover information in the barcode data, so that the paper book is associated with the online electronic book, thereby improving the accuracy of searching for the electronic book corresponding to the paper book and solving the problem of incompatibility between paper book and electronic book resources.

[0131] like Figure 2 As shown, the embodiment of the present invention provides a book information processing device 200, comprising:

[0132] An acquisition module 201 is used to acquire barcode data of a paper book and cover data of a paper book;
