Specifically, as shown in fig. 3 and 4, the second information acquisition unit transmits the acquired information including the bibliographic information, the page number information, and the user reading position information of the book to the second information identification unit, the second information identification unit determines the audio information corresponding to the current reading position of the user according to the bibliographic information, the page number information, and the user reading position information and notifies the audio unit, and the audio unit outputs the corresponding audio information in an audio form, so that the reading process is completed, and the reading type reading for the book is realized. Specifically, the audio information corresponding to the corresponding current reading page or the audio information corresponding to the position in each page of the book that can be read by the user may be audio information pre-stored in a memory, or audio information obtained by text conversion after character recognition, and when the current reading position or the current reading page of the user is determined, the audio information corresponding to the current reading position or the current reading page is sent to an audio unit, and the audio unit plays the audio information through a speaker, so that the reading of the reading position or the reading page content in the book is realized. Further, the corresponding audio information may be information directly corresponding to the text content (i.e. directly reading the text content), or may also be interpretation information, background music, background sound, etc. for the text content, for example, the audio information may be audio information for interpreting a current reading page or audio information for interpreting the text content at a current reading position, or audio information of a book name or a page number, or may also be any sound for the current reading position, for example, the current reading position is a key, and a click sends a corresponding musical instrument sound, for example, the current reading position is an animal, and a click sends a corresponding animal sound, etc.

And relative to the second information acquisition unit and the second information identification unit, the processing functions of the corresponding first information acquisition unit and the corresponding first information identification unit only omit the processes of acquiring the reading position information of the user and identifying the reading position information of the user, but directly identify the current reading page and determine the audio information corresponding to the current reading page. Therefore, the implementation of the first book reader provided by the embodiment of the present invention will not be separately described in detail in the following description.

In the process of identifying the current reading position of the user, the information (i.e. the information collected by the information collection unit) to be used as the basis can be image-text information, infrared information or ultrasonic information. And the reading user can transmit the reading requirement information of the reading user to the book reader through the operation action of the object (such as a stick-shaped object) or the limb action (such as the pointing direction and the sliding of a hand) in the reading process, such as the appointed reading position or the instruction of interacting with the book reader, and at the moment, the information acquisition unit can acquire the object operation action information or the limb action information of the reading user to assist the realization of the corresponding reading process.

In the book reader, the corresponding information collecting unit may specifically include a bibliographic information collecting module for collecting bibliographic information of a book, a page number information collecting module for collecting page number information corresponding to a current reading position, and a reading position information collecting module for collecting reading position information of a user, and the corresponding information collecting module may be disposed in the same processing chip or in different processing chips. Further, as shown in fig. 4, the bibliographic information collecting module may include, but is not limited to, a camera module or a radio frequency signal collecting module or a weight detecting module for collecting image information, radio frequency signals or weight information, the page number information collecting module includes a camera module or a weight detecting module or a radio frequency signal collecting module or an ultrasonic wave detecting module or an infrared detecting module for collecting image information, weight information, radio frequency signals, ultrasonic waves or infrared rays, and the reading position information collecting module includes a camera module or an ultrasonic wave detecting module or an infrared detecting module for collecting image information, ultrasonic waves or infrared rays. If the book information acquisition module, the page number information acquisition module and the reading position information acquisition module adopt cameras to acquire image information, the acquisition of the image information for each module can be respectively carried out through one or a group of cameras uniformly arranged in a book reader; similarly, if the book information collection module, the page number information collection module and the reading position information collection module need other modules with the same function to collect the same type of information, the modules with the corresponding functions uniformly arranged in the book reader can collect the information, such as collecting object operation action information or limb action information of a reading user to assist in realizing the corresponding reading process.

In the book reader, the corresponding camera module may adopt a multi-point image information collecting unit capable of taking multi-angle and/or multi-position multi-point images of the book, and for this purpose, the corresponding camera module may be implemented in any one of the following ways:

(1) the camera module comprises at least one movable camera, and the movable camera controls the movable camera to move based on a preset control mode or received control information so as to shoot multi-angle and/or multi-position multi-point images of the book. For example, the angle and/or position of the movable camera may be automatically adjusted according to feedback automatic control (e.g., automatic adjustment according to feedback after recognition of the captured image), such as when the finger position is out of range or part of the text is out of range or the page number is out of range, so that the product requires no or little manual intervention during the work process, or the camera may be controlled to rotate or move according to control information input by the user (e.g., specific actions performed by the user or predetermined control information input by the user through operating keys, etc.), or the camera may be automatically controlled to rotate or move according to a preset time interval, so as to perform multi-angle and/or multi-position multi-point capturing for the book.

Specifically, the movable camera comprises a rotatable camera and/or a movable camera, that is, the movable camera is rotatable or movable and rotatable; or the movable camera comprises one or more movable lenses; if the movable cameras comprise a plurality of cameras, each camera contained in the movable cameras is used for collecting image-text content information of all or part of scenes; the movable camera can set up in needs gather the position in image information's region includes: above the edges of the area and/or obliquely above and/or directly above.

(2) The camera module comprises a plurality of cameras, namely two or three or four or more than four cameras, the cameras are used for completing multi-angle and/or multi-position multi-point image shooting, each camera is a fixed camera or a movable camera, and the movable camera is used for performing multi-angle and/or multi-position multi-point image shooting on a book based on a preset control mode or based on received control information or manually controlling the movement of the movable camera. For example, the camera is controlled to rotate or move according to control information input by the user (such as specific actions performed by the user or predetermined control information input by the user through operating keys, etc.), or the camera can be automatically controlled to rotate or move according to a preset time interval to perform multi-angle and/or multi-position multi-point shooting for the book.

Specifically, the fixed camera includes one or more lenses, and if the fixed camera includes multiple lenses, the fixed camera controls each lens to acquire the image-text content information based on a predetermined control manner or received control information, and the predetermined control manner includes controlling all or part of the multiple lenses to perform multi-angle and/or multi-position multi-point image shooting to acquire the image-text content information;

each camera included in the plurality of cameras is used for collecting image-text content information of all or part of scenes;

in the scheme (2), the position where the camera module can be arranged in the area where the image information needs to be acquired includes: the cameras may be fixed or movable above and/or diagonally above and/or directly above the edge of the area where the book is located, and the position of the cameras need not affect the reader in reading the book, which is shown in fig. 17, 18, 19 and 20. Meanwhile, due to the fact that the multiple cameras are adopted, shooting coverage required for each camera is greatly reduced, the multiple cameras can shoot respectively to conduct respective recognition work, and shooting results can be integrated for recognition.

(3) The camera module comprises a fixed camera, the fixed camera comprises a plurality of lenses, each lens contained in the plurality of lenses is controlled to collect the image-text content information based on a preset control mode or received control information, so that multi-angle and/or multi-position multi-point image shooting can be carried out on a book through the plurality of lenses, and the preset control mode comprises the step of controlling all the lenses or part of the lenses in the plurality of lenses to carry out multi-angle and/or multi-position multi-point image shooting so as to collect the image-text content information. For example, according to feedback automatic control (e.g. automatic adjustment according to feedback after recognition of the taken images), such as when the finger position exceeds the range or part of the characters exceeds the range or the page number exceeds the range, the angle and/or position of the movable camera is automatically adjusted, so that the product requires no or little manual intervention during the work process, or according to control information input by the user (e.g. fixed actions performed by the user or predetermined control information input by the user through operating keys, etc.), the various lenses are controlled to take multiple angles and/or multiple positions of the book, or the various lenses are controlled to take according to a preset manner that the various lenses acquire image information of multiple angles and/or multiple positions of the book (e.g. the various lenses can be set to take the book in sequence to obtain corresponding image information, it is also possible to set each lens to photograph the book at the same time to obtain corresponding image information, or it is also possible to set a part of the lens to photograph the book to obtain corresponding image information, etc.).

Specifically, in the scheme (3), the position where the fixed camera may be disposed in the area where the image information needs to be acquired includes: above the edges of the area and/or obliquely above and/or directly above, as can be seen in particular with reference to fig. 17, 18, 19 and 20.

The fixed camera usually has a fixed view, but a plurality of cameras can form comprehensive coverage, and the movable camera has a fixed view in a certain angular position, but it changes the view through the activity, therefore can also form comprehensive coverage, in the concrete implementation, if the fixed camera is not flexible, can not regard as the movable camera, likewise, even if the camera is movable, but if the work process does not depend on the activity to obtain the required special effect, such as comprehensive coverage, etc., then still belong to the fixed camera scheme in fact. For example, if the movable camera is adjusted to a proper angle position in advance, but the movable camera does not need to be moved in actual use, or the effect of the movable camera on special effects such as overall coverage is small, the movable camera still belongs to a fixed camera solution in practice.

Specifically, according to different implementation manners of the bibliographic information acquisition module, the specific implementation structures of the corresponding information identification units may also be different, that is, the structures of the information identification units need to be set according to the specific implementation manners of the structure of the bibliographic information acquisition module, as shown in fig. 4, the implementation manners of the corresponding information identification units under different bibliographic information acquisition module structures will be further described below:

(1) if the corresponding book information acquisition module comprises a camera module, the book information acquisition module acquires image information of a book cover (comprising a front cover, a back cover and the like) as book information through the camera module, at the moment, the first information identification unit or the second information identification unit comprises a character identification module or an image identification module or a label identification module, the character identification module identifies characters in the image information of the book cover to determine the book information, namely, the corresponding book name, the image identification module identifies the book name through the image information of the book cover, and the label identification module identifies the book name through a label contained in the image information of the book cover.

Because the front cover image and the back cover image of each book are different, the book can be identified by comparing the shot image information or by extracting characteristic comparison, and the specific book is identified, so that the corresponding book name is determined. In addition, for the convenience of identification, a corresponding label convenient for identification can be further arranged in the book, so that the specific book name of the current book can be determined according to the label, the corresponding label can be a label printed on the book or a label pasted on the book, and the corresponding label can be content information such as pictures, codes or characters. Since the specific image recognition technology is already the prior art, it will not be described in detail here.

Corresponding character recognition has already gradually entered the practical stage, and the corresponding recognition processing procedure may include: firstly, preprocessing a photographed image, wherein the preprocessing mainly comprises binarization, noise removal, inclination correction and the like, and then extracting character features, namely thinning a character image, obtaining the number and the positions of stroke end points and cross points of characters or taking stroke segments as features, and matching a comparison method for comparison so as to recognize the characters. Since the text recognition technology is already the prior art, it will not be described in detail here.

(2) If the corresponding book information acquisition module comprises a weight detection module, the book information acquisition module acquires weight information of the book as book information through the weight detection module, at the moment, the first information identification unit or the second information identification unit comprises a weight identification module, and the weight identification module determines the corresponding name of the book according to the weight information of the book.

Specifically, the weights of different books are usually different from each other, and as long as the weights of the books and the names of the books are stored in a memory of the book reader in advance, the names of the books can be determined according to information stored in the memory after the weights of the books are known through the weight detection module.

(3) If the corresponding book information acquisition module comprises the book information acquisition module, the book information acquisition module acquires electronic tag information arranged in books through the radio frequency signal acquisition module, the first information identification unit or the second information identification unit comprises an electronic tag identification module, the electronic tag identification module determines corresponding book names according to the acquired electronic tag information arranged in the books, namely information of the current books is recorded in the corresponding electronic tag information, and the names of the books can be determined through the identification of the electronic tag information.

Further, in the book reader, the implementation structures of the corresponding information identification units may be different according to different implementation manners of the page number information acquisition modules, and referring to fig. 2, different implementation structures of the corresponding information identification units under different page number information acquisition module structures will be specifically described below:

(1) if the page number information acquisition module comprises a camera module, the page number information acquisition module acquires image information of an inner page of a book as page number information through the camera module, at the moment, the first information identification unit or the second information identification unit comprises an image identification module, a character identification module or a label identification module, the image identification module determines the currently read page number by identifying the image information of the inner page of the book, the character identification module determines the currently read page number by identifying characters or digital page numbers in the image information of the inner page of the book, and the label identification module determines the currently read page number by identifying label information in the image information of the inner page of the book; the image of each page in each book is different, so that the image information can be shot for comparison and identification, or the image information can be extracted for comparison so as to identify which page in which book specifically is, and the scheme that the image identification module identifies the image information of each page in the book to determine which page in the book is the current page can be realized.

(2) If the page number information acquisition module acquires image information of a page turning action of a user through the camera module included in the page number information acquisition module as information containing the page number information or the ultrasonic detection module or the infrared detection module acquires reflection or blocking of ultrasonic waves or infrared rays of the page turning action of the user as information containing the page number information, the first information identification unit or the second information identification unit comprises a page turning action identification module, and the page turning action identification module determines a currently read page number according to the image information of the page turning action of the user and current page information determined before page turning.

The page number of each time of turning of the reader can be defaulted to be one page in the process of recognizing the page turning action, and based on the page number, the page number of the current reading can be determined by counting the page turning number of the reader according to the set counter after the page turning action of the reader is recognized. Or, during the process of recognizing the page turning action, the current page turning number can be determined according to the image of the page turning action (such as according to the information of the thickness of the paper turned over in the image) and the current reading page number can be determined according to the previous reading page.

(3) If the page information acquisition module comprises a weight detection module, the page information acquisition module acquires weight distribution information of the opened book as page information through the weight detection module, the first information identification unit or the second information identification unit comprises a weight identification module, and the weight identification module determines the page number of the current reading according to the weight distribution information of the opened book. Specifically, the weight detection module can be arranged at the position pressed by the book back cover in the book reader, so that when a reader turns over each page of a book, the weight of the book back cover acting on the position of the corresponding weight detection module in the book reader can be changed, and the page number read by the reader at present can be obtained according to the change.

Specifically, along with turning over the page or leaf, books or other picture and text data read the page number of one side more and more, and weight is more and more heavy, and the page number of the other side is less and more, and the weight is more and more light, and weight distribution when weight sensor gathers and detects books or other picture and text data and turns over, converts the signal of telecommunication into and can detect this kind of weight distribution change through analog-to-digital conversion, thereby later with the books that store in advance when turning over weight distribution change information contrast can discern the page number that turns over at present. Further, the identification of different books may also be formed for books of different weights.

(4) If the page number information acquisition module comprises a radio frequency information acquisition module, the page number information acquisition module acquires electronic tag information arranged in a page through the radio frequency signal acquisition module, at the moment, the first information identification unit or the second information identification unit comprises an electronic tag identification module, the electronic tag identification module determines the page number read currently according to the acquired electronic tag information arranged in the page, namely the page number information of the current page is recorded in the corresponding electronic tag information, and the page number read currently can be determined through the identification of the electronic tag information.

Further, in the book reader, the implementation structures of the corresponding information identification units may be different according to different implementation manners of the reading position information acquisition module, and referring to fig. 2, different implementation structures of the corresponding information identification units under different reading position information acquisition module structures will be specifically described below:

(1) if the reading position information acquisition module comprises the camera module, the reading position information acquisition module acquires image information of the reading operation of the user as the reading position information of the user through the camera module, at the moment, the second information identification unit comprises a position identification module, and the position identification module determines the current reading position through identifying the image information of the reading operation of the user; the user reading operation comprises a reading operation performed through limb actions (such as gestures and the like), and also comprises a reading operation performed through actions of an operation object (such as a stick-shaped object and the like); the corresponding position identification module can determine the current reading position by directly identifying the image information of the reading operation of the user, or can determine the current reading position according to the interaction result by identifying the interaction (or called interaction) between the image information of the reading operation of the user and the reading user.

In the processing process of identifying the reading position according to the image information of the reading operation of the user, the reading indication action performed by the hand or the handheld object in the reading process can be specifically identified, including the reading indication action performed by the hand or the handheld object and the coordinate position thereof, so that the reading position of the reader is determined. Specifically, pointing and sliding are two actions commonly used when reading books, usually to point to show attention to a certain place, and gradually read the contents of each page in the book as the finger slides; therefore, the coordinates of the pointing position of the finger can be identified, the voice of the characters corresponding to the pointing position of the finger can be sent out, the coordinate range of the sliding track of the finger can be identified, and the voice of the characters corresponding to the sliding track can be sent out, so that the voice of the corresponding characters can be sent out step by step according to the reading habit of a reader (namely, along with the sliding of the finger of the reader on the book), and the reading of the book can be realized; alternatively, the hand or hand-held object indicates reading of a whole page, or a segment, or a sentence, or a word; in addition, the book reader can also perform interactive operation in the reading process according to gesture actions of the reading user or actions of an operation object, for example, when the reading user is identified to execute a certain preset gesture action or a certain operation, the book reader can inquire whether the reading user performs the reading operation through voice or a display screen, or inquire whether the page number currently read by the reading user is a certain page, and the like, and at the moment, the user can interact with the book reader through operating keys or preset gesture actions in the book reader so as to complete the corresponding reading operation process.

Furthermore, the shot image information of the user reading operation can be subjected to filtering and noise reduction processing, converted into HSV (hue, saturation and brightness) by an RGB (red, blue and green mode) space, a threshold segmentation model is established to perform primary identification on the gesture image, the noise is removed after digital morphology processing and segmentation, and then the positions of the gesture and the fingertip can be identified through searching and geometric identification of a connected domain. Since recognition of gesture motions is a known technique, it is not described in detail here. The identification process for the reading position of the stick is similar to the process of identifying the reading position of the finger, and is simpler than the process of identifying the reading position of the finger, because the stick is simpler than the shape of the hand, has obvious geometric characteristics, and the color or pattern can be customized according to the identification requirement.

For example, for a fixed camera, it is necessary to ensure that a hand or hand-held object falls within the acquisition range of its camera. Considering that the hand or the hand-held object can be at any position of the book, a plurality of photographing cameras or movable photographing cameras can be adopted to collect and cover a plurality of positions of the book, so that the hand or the hand-held object falls in the collection range of the photographing cameras, the hand or the hand-held object is convenient to be photographed and identified, and meanwhile, the corresponding identification accuracy can be improved for more image information collected by the plurality of cameras. And the movable photographing camera can be moved to a proper angle position to photograph and carry out corresponding recognition.

(2) The reading position information acquisition module can also acquire character image information of a user reading operation position as the user reading position information through the camera, the second information identification unit comprises a character identification module and a position identification module, the character identification module is used for identifying the character content of the character image information of the user reading operation position, and the position identification module determines the current reading position according to the character content identified by the character identification module; specifically, information convenient for identification, such as a text position, an image, or content, may be stored in advance as identification reference information, so that the text identification module may match the text after identifying the text, and if the text is matched, the current reading position may be determined.

For example, the corresponding text recognition may include recognition of page numbers, and for a fixed camera, it is necessary to ensure that the page numbers fall within the acquisition range of the camera, so as to ensure that the current page can be turned through the shooting recognition. Considering that the page number may be at any position around the book, a plurality of photographing cameras or movable photographing cameras can be adopted to collect and cover a plurality of positions of the book, so that the page number falls in the collection range of the photographing cameras, the corresponding current page turning and reading can be conveniently photographed and identified, and meanwhile, the corresponding identification accuracy can be improved for more image information collected by the plurality of cameras. And for the movable photographing camera, the movable photographing camera can be moved to a proper angle position for photographing and carrying out corresponding identification on the current page to be turned over.

(3) If the reading position information acquisition module comprises the ultrasonic detection module or the infrared detection module, the reading position information acquisition module acquires the moving position information of the hands or the objects in the book pages as the user reading position information through the ultrasonic detection module or the infrared detection module, at the moment, the second information identification unit comprises a position identification module, and the position identification module identifies the moving position information of the hands or the objects in the book pages to determine the current reading position.

Similarly, the first information identification unit or the second information identification unit may also be applied to other functional modules with the same name and similar functions in the process of identifying the name of the book, the currently read page number or the reading position, and for the situation, the corresponding processing function can be realized through the same functional module without respectively arranging a plurality of modules with similar functions.

For the purpose of facilitating an understanding of the embodiments of the present invention, a detailed description will be given below of an implementation structure of the embodiments of the present invention in a specific application process with reference to the accompanying drawings.

The book reader provided by the embodiment of the invention is shown in fig. 5, and specifically comprises a sensing part, an identification processing part and a sounding part, wherein the sensing part, the identification processing part and the sounding part are electrically connected; the sensing part is a first information acquisition unit or a second information acquisition unit and is used for acquiring sensing information; the recognition processing part is a first information recognition unit or a second information recognition unit and is used as a central processing part for receiving the sensing information collected by the sensing part, finishing recognition processing according to the sensing information and calling corresponding audio information according to a recognition result to send to the sounding part; the sound production part is contained in the audio unit and is used for producing sound corresponding to the content of the reading position of the user so as to realize the corresponding book reading function.

Referring to fig. 5, 6 and 7, the corresponding sensing section may comprise: for example, the system may include only the corresponding optical photographing and shooting module, may also include both the optical photographing and shooting module and the radio frequency identification module, or may also include each module at the same time. The specific functional roles of the respective modules will be described below.

(1) The infrared or ultrasonic detection module, namely the infrared detection module or the ultrasonic detection module, comprises one or more groups of infrared or ultrasonic transmitting and receiving devices, and judges the movement of the user for turning the book and the hand, such as page turning, pointing or sliding and the like, by detecting the reflection or blockage of the infrared or ultrasonic waves. Referring to fig. 6, the turned-up page or hand reflects the infrared or ultrasonic waves emitted by the infrared or ultrasonic sensor group included in the infrared or ultrasonic detection module to the sensor group receiving part included in the infrared or ultrasonic detection module, so as to implement the detection of the corresponding infrared or ultrasonic waves, and perform the identification of page turning and the like based on the detection result.

In fig. 5, two groups of infrared or ultrasonic sensors are specifically adopted and sequentially triggered, so that misjudgment caused by triggering of a single group of infrared or ultrasonic sensors is avoided. In the process of recognizing the page turning action, the page is turned from the right side to the left side along with the progress of the page turning action, and the right sensor group and the left sensor group are sequentially triggered; and then, judging the current page after page turning according to the read page number.

In the process of identifying the specific position of the finger or other object in the reading page, when the finger or other object is placed on the left page, the sensor group arranged on the left side is triggered, and when the finger or other object is placed on the right page, the sensor group on the right side is triggered, so that the reading position is identified; further, if a plurality of groups of infrared or ultrasonic sensors are arranged around the book, the sliding process is identified by triggering the corresponding plurality of groups of sensors at intervals when the fingers slide, and then the sliding position of the fingers can be determined. The recognition effect for the position of finger sliding can be improved if the number of sensor groups is increased around the book.

(2) The radio frequency identification module, i.e., the radio frequency signal acquisition module or RFID chip, as shown in fig. 7, is used to read the electronic tag attached to or made in the book, and the electronic tag may store book information, so that the radio frequency identification module can obtain the bibliographic information of the book after reading the electronic tag, i.e., determine which book is currently read and the specific page number information of the current reading. At present, the electronic tag can be very thin, so that the electronic tag can be pasted or directly made into a book page; moreover, the information storage capacity of the electronic tag is more and more, and the electronic tag can store information such as book names, page numbers and audio information corresponding to contents, so that the radio frequency identification module can conveniently obtain corresponding information.

(3) An optical photographing and shooting module, as shown in fig. 9, fig. 10 and fig. 11, may include a photographing camera, i.e., a camera, which may be fixed or movable, and may be disposed on the upper portion of the book reader and face the book, and the disposed position does not affect the reader to read the book; further, the arrangement of the camera may only be to shoot a part of the covered book, or may also be to shoot by rotating or moving the camera so as to achieve the maximum shooting coverage without distortion in a short distance, in addition to considering the long-distance shooting or the wide-angle lens solution which is usually used to achieve the required shooting coverage, in order to make the shooting distance practical and avoid the image distortion caused by the wide-angle lens.

The corresponding optical photographing and shooting module may also include a plurality of photographing cameras, as shown in fig. 12, 13 and 14, that is, a plurality of cameras, and similarly, the corresponding plurality of cameras may be fixed or movable and disposed on the upper portion of the book reader facing the book, and the disposed position does not affect the reader reading the book; due to the fact that the plurality of photographing cameras are adopted, photographing coverage required by each photographing camera is greatly reduced, the plurality of photographing cameras can respectively photograph and carry out respective recognition work, and photographing results can be integrated for recognition.

In a word, the corresponding shooting process of optical recognition through the optical photographing and camera shooting module can only cover one part of the book and can also cover the whole book. In the process of identifying the book, the book may be identified by identifying an identification code (such as a bar code in fig. 15) printed on the book, or the book may be identified by identifying characters on the book, or the book may be identified by extracting image features of the book, or the book may be identified by identifying a tag attached to the book. The optical photographing and camera shooting module can also identify the page number of the book through optical photographing, for example, the page number can be identified through identifying the page number (as shown in fig. 16), or the page number can be identified through identifying characters on the page, or the page number can be identified through extracting image features of the page. In addition, the optical photographing and camera shooting module can also be used for identifying the action of a hand or a handheld object on a book, including identifying whether the current action is a book turning action, identifying the coordinate position of the action in a book page to determine the current reading position, identifying the sliding area of the action in the book page to determine the current sliding range, and taking the corresponding sliding range as the range of the current reading content.

Still referring to fig. 5, the corresponding recognition processing part is a central processing module, i.e. a first information recognition unit or a second information recognition unit, for completing the recognition processing of information by the corresponding CPU part, performing the storage processing of book information and other processing information by the corresponding storage part, and performing the communication processing with other modules by using the corresponding communication interface and input/output part, and the recognition processing part may further include a display part for displaying information during the processing, such as currently read page information or book order information. The identification processing part can also comprise an expansion storage part for expanding the storage space so as to be convenient for storing more book information. The recognition processing part can receive the information of the sensing part and complete recognition processing, and then call the corresponding audio information from the storage part and send the audio information to the sound production part, or the recognition processing part can directly recognize the text content of the content part according to the information transmitted by the sensing part, convert the corresponding text content into the audio information and send the audio information to the sound production part.

As shown in fig. 5, the sound generating portion is included in the audio unit, and includes a sound generating module and a speaker, where the sound generating module may include a codec unit and a driving unit, and is configured to receive information audio information of the central processing module, process the information audio information and transmit the processed information audio information to the speaker, so as to generate audio sound through the speaker, and the corresponding speaker may be an earphone or a sound box. The corresponding codec unit is set only when the audio information stored in the recognition processing part needs to be codec, and the codec unit may be set in the recognition processing part if necessary.

The audio information of the books stored in the recognition processing part can be any kind of voice, such as Chinese, English and the like, so that the book reader provided by the embodiment of the invention can be used for reading books of various languages. Meanwhile, the sound emitted may be a sound corresponding to the text content, or may be other preset sounds, such as a sound content, such as an explanation of the text content, and the like.

The implementation of the embodiment of the invention provides a book reader which can read common books in a natural way, and is convenient for people who cannot read the books directly to read the common books.

Furthermore, multipoint image acquisition can be realized through the book reader, and the object to be acquired can be covered by the corresponding multipoint image acquisition in a close range without distortion. Specifically, a plurality of focal lengths are provided for the corresponding movable camera or cameras, so that all parts of the collected object are at the best focal length to ensure that the images of all parts are clear. For example, referring to fig. 21, 22, 23, 24 and 25, since a multi-camera or a movable camera (e.g. a rotatable camera) is adopted, a curved surface (e.g. a large curved surface in the middle of a book) can always have a proper shooting angle and position, so that the curved surface can be effectively shot and recognized, the shooting object can be effectively shot by the corresponding shooting angle whether the shooting angle is right above or inclined from the side, and each part is in a good focal distance to obtain a clear image and good resolution. Moreover, the corresponding multi-point image acquisition has lower requirement on the resolution of the camera, or the camera with the same resolution can shoot the shot object to achieve higher resolution (more beneficial to identification).

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
