Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.

It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.

The term "include" and variations thereof as used herein are open-ended, i.e., "including but not limited to". The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions for other terms will be given in the following description.

It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.

It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.

In some current touch and talk pens, a camera is mounted in a pen head, so that information written on paper with fine squares can be stored in the pen in a data manner and can be transmitted through bluetooth or a Universal Serial Bus (USB). The touch and talk pen can input writing information and character tracks, but cannot be used for text recognition, and the biggest problem is that a writing book needs to be customized and needs to have fine-grid stripes because the principle is that dot matrix recognition of a camera is adopted.

Based on this, the present disclosure provides a text processing method and apparatus that may not be limited by a book.

As shown in fig. 1, an embodiment of the present disclosure provides a text processing method, including a step S101 of acquiring a target image of a text in response to a preset operation event. In some embodiments, the embodiments of the present invention are applicable to image processing apparatuses, such as a stylus with a camera, a mobile terminal, and the like. In some embodiments, the preset operation event includes a manual trigger event and an automatic trigger event, the manual trigger event may be triggered by a text recognition key/button, the automatic trigger event may be automatically triggered when a camera on an image processing device (e.g., a touch-and-talk pen) is focused successfully, or triggered by receiving a voice instruction sent by a user. In some embodiments, this is automatically triggered when the image processing device (e.g., a stylus) writes on a book or paper.

The method further comprises the step S102 of carrying out image splicing on the target image to obtain a spliced image. The image stitching technology is a technology for stitching a plurality of images with overlapped parts (which may be obtained at different times, different viewing angles or different camera sensors) into a seamless panoramic image or a high-resolution image. The splicing method based on feature template matching feature points is used more. The method allows the images to be spliced to have certain inclination and deformation, overcomes the problem that the axes of the images must be consistent when the images are obtained, and simultaneously allows certain chromatic aberration between the adjacent images. The splicing of the panoramic image mainly comprises the following four steps: pre-splicing the images, namely determining the accurate position of the superposition of two adjacent images, and laying a foundation for searching the characteristic points; extracting the characteristic points, namely finding the characteristic points to be matched after the basic coincidence position is determined; image matrix transformation and splicing, namely establishing a transformation matrix of the image according to the matching points and realizing the splicing of the image; and finally, smoothing the image. It is to be understood that the above description is intended to be illustrative, and not restrictive, of the present disclosure. In some embodiments, image integration of a whole page of text may be performed while writing, by stitching of images, similar to taking with a panoramic camera.

In some embodiments, the method of the present disclosure further includes modifying the stitched image to obtain a modified text image. In some embodiments, because the stylus is typically tilted, the image captured by the stylus is typically tilted and does not facilitate viewing or recognition of the captured text. Thus, modifications, e.g., distortion correction algorithm processing, can be made to the stitched image to make the text image more convenient for viewing and later text recognition.

By adopting the method disclosed by the invention, the whole page of image can be acquired without being limited to a special book, and the corresponding writing track can be recorded for teaching analysis. In addition, after the job or the writing scene is finished on the book, the image data of the whole page of text can be obtained without a third-party shooting device (such as a mobile phone or a high-speed camera).

The method of the present disclosure may further include performing text recognition on the text image to obtain a recognized text. In some embodiments, the text image is text recognized by an optical character recognition algorithm. In some embodiments, the text in the text image is recognized by an Optical Character Recognition (OCR) algorithm to obtain corresponding text data, which includes all characters, all words/single words, coordinates of the characters or words/words with respect to the upper left corner of the target image, all line texts, and so on. By adopting the method disclosed by the invention, the text recognition can be carried out on the image of the existing document, the text recognition can also be carried out on the image of the writing track, and a special book is not needed.

In some embodiments, the method of the present disclosure further comprises: while acquiring a target image of the text, acquiring an angle between a longitudinal extension direction of the device and a gravitational force direction, and performing text recognition on the spliced image by using the angle assistance. In some embodiments, the device may include a regular pen, a point-and-read pen, a smart pen, and the like. In some embodiments, the method of the present disclosure further comprises: while acquiring a target image of the text, acquiring an angle between a longitudinal extension direction and a horizontal direction of the device, and using the angle to assist text recognition of the stitched image. It should be understood that the paper may be considered to be at a horizontal angle when writing or reading is normally performed. Through the introduction of the angle factor, the image can be better corrected by correction processing (such as distortion correction algorithm processing). Because the angle of the pen grip may vary from person to person, but is within a reasonable range.

As shown in fig. 3, a paper sheet 20, a device 21 and an assembly 22 are shown. In some embodiments, the device 21 and the assembly 22 may be separate, in which case the device 21 may be a conventional ball-point pen, fountain pen, or the like, and the assembly 22 may be secured to the device 21 using a clip or the like.

In some embodiments, the device 21 and the component 22 may be integrated, constitute a smart pen, both for normal writing and capturing writing traces, etc. In some embodiments, as shown in fig. 3, direction 23 is the direction of longitudinal extension of device 21, and direction 24 may be a horizontal direction parallel to the plane of the paper or other direction set as desired, e.g., any suitable direction closer to direction 23 than to direction 24.

In some embodiments, the angle of the device 21 and the gravity direction is obtained by using an angle sensor, and the angle is used for the auxiliary component 22 (including a camera) and a corresponding algorithm to perform recognition processing of characters and pictures.

In some embodiments, obtaining the target image of the text comprises: an image of the object within a viewing angle between a longitudinal extension direction of the device and a horizontal direction is acquired. As shown in fig. 3, the target image may be obtained within a viewing angle between the direction 23 and the direction 24. In some embodiments, the cameras of the assembly 22 may surround the entire device 21, so that the target image can be acquired from various angles without dead angles, and then a complete text image is obtained through image stitching, and then a more complete and accurate text is identified.

In some embodiments, the present disclosure further comprises: and responding to another preset operation event, and performing voice broadcast on part or all of the recognized text. For example, the component 22 may include a microphone, speaker, etc., which in turn may enable speech playback of recognized text. Additionally, in some embodiments, the component 22 may engage in voice interaction with the user. In some embodiments, the reading function may be implemented by recognizing the text of the image at the reading position, i.e., the recognized text is instantly broadcasted by voice. Therefore, the method can realize the point reading, scanning and recording of the existing document, can also realize the recording of the writing track, and can also carry out text recognition on the existing document or the writing track.

In some embodiments, the method of the present disclosure further includes projecting infrared projected light or visible projected light onto the paper surface 20 of the text for assisting in the recognition of the text. For example, the assembly 22 may include an infrared projection lamp, a visible projection lamp, and the like, may project a dot matrix light source, and the like, to assist in text recognition of the image.

The method disclosed by the invention can be used for splicing the target images firstly and then correcting the target images, as shown in fig. 2, the method disclosed by the invention can also be used for correcting the target images firstly and then splicing the corrected target images. Accordingly, another method of the present disclosure may include steps S101, S202, and S203. Step S202, correcting the target image to obtain a corrected target image; and step S203, carrying out image splicing on the corrected target image to obtain a spliced text image. Namely, the difference from the previous method is that the order of modification and splicing is different, and other related steps are the same as the description of the previous method and are not repeated here.

In some embodiments, the processor 43 is further configured to identify a target image of the stitched and/or modified text, resulting in an identified text.

In some embodiments, the text processing device may further include a wireless communication component for data transmission of the text processing device with an external component. In some embodiments, the acquired text image may be processed and identified in the text processing device, or may be sent to the cloud for processing through a wireless communication device such as bluetooth. That is, the wireless communication component can facilitate communication with cloud services or other devices.

In some embodiments, the text processing apparatus may include a gyroscope, and a relative angle between the device and the paper surface may be known through the gyroscope, so that the relative angle is fed back to the processing chip, and through an increase in an angle coefficient, a distortion correction algorithm in text image recognition may better perform distortion processing on the text image. Because the included angles of the pen-holding of different people are different but are within a relatively reasonable range. The relative angle can assist in the recognition of the text image.
