All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the process of learning Chinese characters by using the teaching interactive terminal, the Chinese characters to be recognized need to be input in the teaching interactive terminal, the Chinese characters to be recognized are searched in the Chinese character library, and then the Chinese characters are displayed or played in voice through the teaching interactive terminal, but the Chinese characters are searched only by depending on the handwriting input mode of parents, so that the use convenience is low.
Therefore, the technical problem is solved, the target Chinese character in the voice input information can be identified by acquiring the voice input information of the user, the Chinese character to be recognized is searched in the Chinese character library, and the strokes of the target Chinese character can be displayed according to the stroke sequence, so that the user can conveniently check and learn interaction.
The first embodiment is as follows:
according to the above content, the present application provides a teaching interactive terminal, as shown in fig. 3, including a housing, and a voice input unit, a main control unit and a display unit arranged in the housing, wherein a power module for providing the teaching interactive terminal is further arranged in the housing.
In this application, the speech input unit is used for acquireing user's speech input information, and the speech input unit adopts the adapter, and the speech input unit sets up on the casing, and speech input unit electric connection is in the main control unit, and the speech input unit is used for transmitting the speech input information who acquires to the main control unit.
As shown in fig. 4A, the main control unit includes a voice module for parsing and extracting a target chinese character to be queried from the voice input information, and a search module for traversing a preset chinese character library to search for the target chinese character, where strokes corresponding to each chinese character are stored in the chinese character library.
The main control unit is also connected with a storage unit, a Chinese character library is stored in the storage unit, and strokes and stroke sequences corresponding to each Chinese character are stored in the Chinese character library. As shown in fig. 4B, the voice module includes a voice conversion module and a chinese character extraction module. The voice conversion module is used for analyzing the voice input information to convert and generate character input information; the Chinese character extraction module is used for matching according to the preset language character string sequence based on the character input information so as to extract the target Chinese character to be inquired. It is noted that the predetermined language string includes a sequence-based combination of the target kanji and the key string.
Specifically, the following examples are given. If the user uses the teaching interactive terminal, the user speaks 'how the ox listens and how the ox character is written', therefore, the voice input unit acquires the voice input information 'how the ox listens and how the ox character is written', the voice conversion module converts the voice input information into the character input information 'how the ox listens and how the ox character is written', and therefore the Chinese character extraction module can identify the character input information so as to be matched according to the preset language character string sequence to extract the target Chinese character 'ox' to be inquired. The preset language character string includes a combination of a target Chinese character and a key character string based on sequence, for example, the target Chinese character is 'ox', the key character string is 'how to write a word', and the key character string can be set by a user, for example, the key character string includes but is not limited to 'how to write a word', and the like.
It should be noted that a plurality of key character strings may be set for matching, and after one of the key character strings is matched, the text input information may be extracted according to a preset language character string.
Therefore, the target Chinese character can be accurately extracted only according to the arrangement sequence of the target Chinese character and the key character string. Therefore, the target chinese character is arranged before the key character string or after the key character string, and is set by the user according to the requirement, which is not limited in this embodiment.
After the voice module extracts the target Chinese character from the voice input information, the search module traverses a preset Chinese character library in the storage unit to search the target Chinese character, and correspondingly obtains the stroke and stroke sequence of the target Chinese character. Therefore, the display unit is used for displaying the target Chinese character and the strokes of the target Chinese character according to the stroke sequence. In one embodiment, the display unit is an LED display screen arranged on the shell; in another embodiment, the display unit is a liquid crystal display disposed on the housing, and the display unit is connected to the master control unit.
It should be noted that if the search module traverses the chinese character library and does not search for the target chinese character, i.e., the chinese character library does not store the target chinese character, the search failure will be displayed on the display unit and the user will be prompted to make up in the chinese character library.
According to the method and the device, the target Chinese character in the voice input information can be extracted by acquiring the voice input information of the user, and then the strokes of the target Chinese character can be displayed according to the stroke sequence, so that the user can conveniently check and learn interaction, the user does not need to perform hand-typing and knocking input, and the convenience in use of the user is improved.
The teaching interactive terminal is used for further improving the use convenience of the teaching interactive terminal and the interest and the ability of the user for learning Chinese characters. After the target Chinese character to be learned is extracted, the current writing image of the user can be collected to further recognize the writing handwriting of the user, whether the user writes according to the stroke and stroke sequence of the target Chinese character is judged, and therefore the use convenience of the user is further improved, and the interestingness of interaction is further improved.
Specifically, as shown in fig. 3, the teaching interactive terminal further comprises an image acquisition unit, the image acquisition unit adopts a camera, the image acquisition unit is arranged on the shell, and the image acquisition unit is connected to the main control unit. If the teaching interactive terminal is placed on the desktop, the image acquisition unit shoots the image of the desktop at an inclined angle.
The image acquisition unit is used for acquiring a current writing image of a user, wherein the current writing image carries a current writing, therefore, after a target Chinese character to be learned is extracted, the teaching interaction terminal enters a teaching mode, the user (children) writes on the desktop paper at the front side of the teaching interaction terminal in contrast to the target Chinese character, and a writing tool can adopt a ball pen, a fountain pen or a writing brush, therefore, the current writing of the user is formed on the paper, the image acquisition unit of the teaching interaction terminal acquires the current writing image of the user in real time, the acquisition interval of the image acquisition unit is between 0.1s ~ 0.5.5 s,
in this embodiment, the collection interval of the image collection unit is 0.2s, but the collection interval of the image collection unit is not specifically limited, and can be set according to the needs of the user, the writing speed of the user (children) is slow, and the collection interval of the image collection unit can be adaptively increased according to the actual situation. Therefore, the current writing image acquired by the image acquisition unit carries the current writing.
As shown in fig. 5A, the main control unit further includes a stroke extracting unit and a stroke matching unit. The stroke extraction unit is used for analyzing the current writing image and extracting writing handwriting in the current writing image to be used as the current writing stroke; the stroke matching unit is used for matching and comparing the current writing stroke with the stroke based on the stroke sequence of the target Chinese character, and eliminating the current writing stroke when the current writing stroke is not matched with the stroke sequence of the target Chinese character.
Specifically, if the target Chinese character extracted by the user according to the above technical scheme is "ox", and the user writes on the paper based on the stroke of the target Chinese character "ox", and leaves a written handwriting on the paper, and leaves a current written handwriting in the current written image. The stroke extraction unit is used for analyzing the current writing image to extract the writing in the current writing image as the current writing stroke. The following description is given by taking a 'cattle' as an example, such as strokes and stroke sequences of 'cattle' words as 'horizontal', 'horizontal' and 'vertical', therefore, when a user writes the first stroke of 'cattle' words, the current writing left on paper is 'horizontal', therefore, the current writing is taken as the current writing stroke to match and pair with the current writing stroke according to the first stroke of 'cattle' words, and when the current writing stroke is matched with the stroke sequence of a target Chinese character, the teaching interactive terminal sends out 'correct' prompt information. On the contrary, when the current writing stroke is not matched with the stroke sequence of the target Chinese character, the current writing stroke is eliminated so as to facilitate the user to rewrite the first stroke of the 'cattle' character, and the 'error' prompt message is sent out so as to facilitate the user to know.
When a user is a child of an appropriate age and writes on paper with a pen, the current written notes left on the paper may be skewed or written in an abnormal manner, so that the current written handwriting is recognized with low accuracy.
In order to solve the above technical problem and improve the recognition accuracy of the current written handwriting, in the present application, as shown in fig. 5B, the stroke extracting unit includes an image processing module, a stroke matching module, and a stroke generating module.
The image processing module is used for carrying out binarization processing on the current writing image based on the current writing image of the current frame so as to obtain the current writing in the current writing image; the stroke matching module is used for matching and comparing the current writing handwriting with strokes in a standard stroke library; and the stroke generation module is used for replacing the current writing handwriting with the corresponding stroke in the standard stroke library as the current writing stroke after the current writing handwriting is successfully matched with the stroke in the standard stroke library.
Specifically, since the user writes on the paper is a continuous process, the current writing in each current writing image will be a continuous and simple process, i.e. the current writing in the next current writing image will have a larger amount of content than the current writing in the previous current writing image.
Therefore, the image processing module performs binarization processing on the current writing image based on the current writing image of the current frame, so as to obtain the current writing according to the gray value of each pixel in the current writing image after binarization processing, and further to obtain the situation that the current writing may be inclined or incomplete, such as the first stroke of the Chinese character 'niu' or 'le', the situation that the current writing only writes two thirds or 'le', or the disorder of the writing.
At this time, the stroke matching module matches and compares the current writing with the strokes in the standard stroke library, and when the matching degree between the current writing and the strokes in the standard stroke library reaches a preset ratio, the matching is successful, and in this embodiment, the preset ratio is set to 80%. Therefore, the stroke generation module is used for replacing the current writing handwriting with the corresponding stroke in the standard stroke library as the current writing stroke after the current writing handwriting is successfully matched with the stroke in the standard stroke library.
Therefore, the current writing stroke is replaced by the stroke in the standard stroke library to serve as the current writing stroke, and the problems that the current writing stroke is not standard or the writing integrity is not enough can be solved.
Through the technical scheme, after the target Chinese character to be learned is extracted, the writing of the user can be recognized, and then whether the user writes according to the stroke and stroke sequence of the target Chinese character is judged, so that the use convenience of the user, the interest of interaction and the convenience of learning the writing of the target Chinese character are further improved.
