Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary reading, and in particular to an auxiliary reading device and method based on image code shielding. Background Art

[0002] The auxiliary reading device detects and recognizes the text part of the image on the reading table with the help of text recognition technology, forms text data, converts it into sound signals and outputs the sound signals, mainly providing text reading assistance for the blind, the visually impaired and the visually impaired, the elderly and children. However, the current auxiliary reading device still requires the user to put the object to be read on the reading table, and then notify the auxiliary reading device to start the image recognition on the reading table through the user's key input, voice input or other input methods, which increases the difficulty of operating the auxiliary reading device. For example, Chinese patent CN210955115U discloses a desktop auxiliary reading device, which uses a bracket to fix an electronic reader, and includes: a bracket; an electronic reader fixed on the bracket, which is configured to recognize the text in the image to be recognized and generate text data; and a control component, which includes a body and an input control arranged on the body, and the input control is electrically connected to the electronic reader so that the user can control the operation of the electronic reader through the input control. The auxiliary reading device controls the operation of the reader through the user's operation control parts, and the user needs to be familiar with the functions and usage methods of all the control parts. This is very inconvenient for the blind, the visually impaired, the elderly and the children, and is not convenient for such people to use. For example, Chinese patent CN211632405U discloses an intelligent auxiliary reading device, which includes an automatic book picking device for automatically clamping books, a book transport device for transporting books on the bookshelf to the reader, a reading board device for assisting reading, and an automatic book placing device and a control device for putting the books that the reader has read back to the bookshelf; an intelligent auxiliary reading device that can automatically and integratedly realize the picking up of books, transporting books, assisting in page turning and putting back books.

[0024] The details of the present invention can be more clearly understood with reference to the accompanying drawings and the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only used for the purpose of explaining the present invention and cannot be understood as limiting the present invention in any way. Under the guidance of the present invention, technicians can conceive of any possible variations based on the present invention, which should all be deemed to belong to the scope of protection of the present invention.

[0025] like Figure 1-3 As shown, an auxiliary reading device based on image code of the present invention comprises a central processor 1, a voice unit 2, an image acquisition unit 4, a reading platform 5 and an image code 6; wherein the central processor 1 and the voice unit 2 are arranged on the reading platform 5; the central processor 1 is connected to the image acquisition unit 4 and the voice unit 2; the image code 6 is arranged on the reading platform 5 or on the surface of the object to be read 7; the image acquisition unit 4 acquires the image of the image code 6 and sends the acquired image of the image code 6 to the central processor 1. The image code 6 is provided with an invalid shielding area, and the invalid shielding area corresponds to the position information of the object to be read 7 on the reading platform 5, and the position information of the object to be read 7 is acquired by the image acquisition unit 4 and recognized by the central processor 1; the recognized position information of the object to be read 7 is played through the voice unit 2. The voice unit 2 plays the voice according to the received voice information. The voice unit 2 can play languages ​​or dialects of different countries.

[0026] The image acquisition unit 4 is selected from a fixed camera, a mobile terminal camera or other types of camera equipment.

[0027] like Figure 1-3 As shown, the reading platform 5 is provided with a side panel 3, which is arranged at the periphery of the image code 6 to define the boundary position of the object to be read 7. The side panel 3 can be in the form of a planar plate, a strip plate or a plate of other shapes; the side panel 3 can be used as a baffle for the object to be read, so that the object to be read is limited to a certain position range. The side panel 3 and the image code 6 together define and identify the position of the object to be read.

[0028] like Figure 4-5 As shown, the image code 6 can be a barcode, a two-dimensional code or a three-dimensional code. A part of the image code 6 is provided with an invalid shielding area, which is provided in a part of the image code 6. The image acquisition unit 4 can recognize the whole image code 6 including the invalid shielding area. When the object to be read shields the invalid shielding area of ​​the image code 6, the image acquisition unit 4 cannot recognize the image code 6. In this way, the invalid shielding area of ​​the image code 6 corresponds to the position information of the object to be read 7 on the reading station 5. The position information of the object to be read 7 is collected by the image acquisition unit 4 and recognized by the central processor 1; the recognized position information of the object to be read 7 is played through the voice unit 2.

[0029] The image code 6 can be set to one or more, and can also include a boundary positioning image code and an internal identification image code. The boundary positioning image code is distributed around the internal identification image code; the internal identification image code is distributed inside the boundary positioning image code. Among them, the geometric center connection line of the said blocked invalid area of ​​at least three image codes 6 is a straight line; preferably, the straight line is a horizontal straight line, a vertical straight line or a straight line in other directions. The types of multiple image codes 6 can be the same, such as bar codes; or different types, such as a combination of bar codes and QR codes.

[0030] In addition, the auxiliary reading device further comprises a storage unit and a remote transmission unit, wherein the storage unit stores the voice information corresponding to the image code 6. The remote transmission unit transmits the auxiliary reading related information to the host computer.

[0031] The present invention provides an auxiliary reading method based on image code, which is based on the previous auxiliary reading device, and the auxiliary reading steps include:

[0032] Place the object to be read 7 on the reading table 5;

[0033] The image acquisition unit 4 acquires an image of the image code 6 and sends the information of the image code 6 to the central processor 1;

[0034] like Figure 4-5 As shown, when the blocked invalid area of ​​the image code 6 is blocked, the central processor 1 determines that the object to be read 7 is on the image code 6; when the blocked invalid area of ​​the image code 6 is not blocked, the central processor 1 determines that the image code 6 is not blocked by the object to be read 7, thereby determining the position information of the object to be read. The voice unit 2 plays the position information of the object to be read.

[0035] After the position of the object 7 is determined by the auxiliary reading device, the image acquisition unit 4 starts to acquire the text on the object 7 and transmits it to the central processor 1 for reading, and the voice unit 2 plays it.

[0036] In addition, the image code 6 is set to one or more, and the position information of the object to be read 7 can also be determined through the blocked information of multiple image codes 6. Figure 1 The number of image codes 6 in is one, Figure 2 The number of image codes 6 in is multiple.

[0037] Among them, Figure 2As shown, the geometric center line connecting the blocked invalid areas of at least three image codes 6 is a straight line; preferably, the straight line is a horizontal straight line, a vertical straight line or a straight line in other directions. The types of multiple image codes 6 can be the same, such as barcodes; or different types, such as a combination of barcodes and QR codes. After determining the position information of the object to be read 7, the central processor 1 identifies the angle between the outline of the object to be read 7 and the straight line to determine the angle of rotation and / or the direction of movement required for adjusting the object to be read 7 to a suitable position for auxiliary reading, and the voice unit 2 broadcasts the required angle of rotation and / or direction of movement.

[0038] The image code 6 may also include a boundary positioning image code and an internal identification image code, wherein the boundary positioning image code is distributed around the internal identification image code; and the internal identification image code is distributed inside the boundary positioning image code. When the object to be read 7 blocks the boundary positioning image code, the central processing unit 1 determines the position information of the object to be read 7 based on the invalid boundary positioning image code. In addition, when the object to be read 7 blocks the boundary positioning image code and the internal identification image code, the central processing unit 1 determines the position information of the object to be read 7 based on the invalid boundary positioning image code and the invalid internal identification image code; and determines the angle of rotation and / or the direction of movement required to adjust the object to be read 7 to a suitable position for auxiliary reading, and the voice unit 2 broadcasts the required rotation angle and / or direction of movement.
