Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, which is a schematic flow chart illustrating an implementation process of a method for determining repeated strokes according to an embodiment of the present invention, where the method is applied to a terminal device, as shown in the figure, the method may include the following steps:
step S101, acquiring characters written by a user.
In the embodiment of the present invention, the character written by the user refers to a character handwritten by the user, for example, a character handwritten by the user through a touch and talk pen, and specifically, may refer to a dot matrix formed by combining tracks of strokes input by the user. The characters written by the user can be obtained locally from the terminal device or from a server. The characters written by the user can be pre-stored or can be collected in real time through an input collection device. For example, after the terminal device starts a character writing function, if the terminal device receives an instruction to acquire a character written by a user, the terminal device acquires the character written by the user from the terminal device locally or from a server, or if the terminal device receives operation information of the character written by the user, the terminal device acquires the character written by the user. It should be noted that the terminal device may detect at preset time intervals or detect in real time whether an instruction to acquire a character written by a user is received, or receive operation information of the character written by the user. The characters include, but are not limited to, characters (e.g., chinese characters), numbers, letters, etc., and are not limited thereto.
For example, after the point reading machine is started, a character writing function is started, the exercise book is placed on a sensing panel of the point reading machine, and when characters input on the exercise book by a user through a point reading pen are detected, all stroke tracks input by the user are collected to obtain a dot matrix formed by all the stroke tracks.
Step S102, recognizing the characters written by the user to obtain standard characters matched with the characters written by the user.
In the embodiment of the present invention, after obtaining a character written by a user, normalization processing may be performed on the character written by the user, and the size of the character written by the user is adjusted to a preset standard size so as to reduce an error when the character written by the user is recognized, and then the character written by the user is recognized, specifically, each standard character in a character database locally stored in the terminal device is matched with the character written by the user one by one, so as to determine a standard character corresponding to the character written by the user, that is, a standard character matched with the character written by the user. It should be noted that, in the embodiment of the present invention, the character written by the user may also be recognized in other ways, which is not limited herein.
Optionally, the recognizing the character written by the user to obtain a standard character matched with the character written by the user includes:
and acquiring the matching degree of the characters written by the user and standard characters in a character database, and taking the standard character with the highest matching degree with the characters written by the user as the standard character matched with the characters written by the user.
In the embodiment of the present invention, the character database refers to a database in which standard characters of all existing characters are stored.
Optionally, the recognizing the character written by the user to obtain a standard character matched with the character written by the user includes:
acquiring the matching degree of the characters written by the user and standard characters in a character database, and taking the standard characters with the matching degree of the characters written by the user within a preset range as candidate standard characters;
selecting one standard character from the candidate standard characters as a standard character matched with the character written by the user.
In the embodiment of the present invention, when the terminal device uses a standard character whose matching degree with the character written by the user is within a preset range as a candidate standard character, the candidate standard character may be displayed on a screen of the terminal device for the user to select, receive a standard character selected by the user from the candidate standard character, and use the selected standard character as a standard character matching with the character written by the user. The preset range may be set according to actual needs, for example, 70% to 100%, and is not limited herein.
Optionally, the selecting a standard character from the candidate standard characters as a standard character matching the character written by the user includes:
and if a certain standard character in the candidate standard characters is detected in the scene that the user writes the characters, taking the standard character as a standard character matched with the characters written by the user.
In the embodiment of the present invention, the scene in which the user writes the character may refer to a screen of the terminal device or a textbook placed on an induction panel of the terminal device when the user writes the character. For example, before the user writes the character, a standard character of the character to be written by the user is displayed on the screen of the terminal device, and if the standard character of the character to be written by the user on the screen of the terminal device is detected in the candidate standard characters, the standard character is used as a standard character matched with the character written by the user. Or before the user writes the characters, placing the textbook on a sensing panel of the terminal equipment, and if one standard character in the candidate standard characters is detected on the current page of the textbook, taking the standard character as the standard character matched with the characters written by the user.
Step S103, respectively obtaining the stroke number of the user writing the character and the stroke number of the standard character.
In the embodiment of the present invention, the terminal device respectively obtains the number of strokes when the user writes the character and the number of strokes of the standard character matched with the character written by the user, and compares the number of strokes when the user writes the character with the number of strokes of the standard character (that is, the number of strokes of the standard character matched with the character written by the user), and if the number of strokes when the user writes the character is greater than the number of strokes of the standard character, it is detected whether at least two strokes in the character written by the user are the same; if the number of strokes of the user writing the character is equal to the number of strokes of the standard character, determining that the character written by the user is correct, namely the character written by the user is the standard character; and if the stroke number of the user writing the character is smaller than that of the standard character, determining that the character written by the user is not the standard character.
After the fact that the characters written by the user are correct is determined, the characters written by the user are subjected to normative judgment so as to detect whether the characters written by the user are normative or not, a normative recognition result of the characters written by the user is obtained, and the normative recognition result is displayed on a screen of the terminal equipment so that the user can know whether the characters written by the user are normative or not. The normative recognition result comprises a normative recognition sub-result for each stroke in the character handwritten by the user. The normative recognizer result includes metric values describing whether the stroke relative position, length, width, radian and/or stroke shape are normative. The relative position of the stroke includes, but is not limited to, the spacing between the stroke and other adjacent strokes, the spacing between the architecture in which the stroke resides and other architectures in the character written by the user. Stroke length refers to the distance a user travels during the writing of the stroke from the start of the stroke to the end of the stroke. The stroke width refers to the thickness of the stroke when the user writes the stroke. The stroke radian is the radian of a hook and/or a break hook contained by a stroke. The stroke gesture refers to the starting, stopping and front of a stroke.
It should be noted that the case that the number of strokes of the user writing the character is smaller than the number of strokes of the standard character does not generally occur, because when the standard character matched with the character written by the user is obtained in step S102, the standard character is generally recognized according to the stroke track of the user writing the character, and if the user writes one less stroke or more than one stroke when writing the character, the recognized standard character is different. For example, when the user writes a 'king', the user writes the top horizontal less, and the recognized standard character is 'soil', but not 'king', namely the user writes a mistake.
And step S104, if the number of strokes of the character written by the user is different from the number of strokes of the standard character, extracting the same strokes from the character written by the user.
In this embodiment of the present invention, if the number of strokes when the user writes the character is greater than the standard character (i.e., the standard character matching the character written by the user), it is detected whether the same strokes exist in the character written by the user, and if it is detected that the same strokes exist in the character written by the user, it is detected whether the same strokes extracted from the character written by the user are adjacent in order of strokes, and whether the same strokes extracted from the character written by the user overlap, where the overlap includes, but is not limited to, partial overlap and full overlap.
Step S105, if the stroke orders of the same strokes extracted from the characters written by the user are adjacent and the same strokes are overlapped, determining that the same strokes extracted from the characters written by the user are repeated strokes.
In this embodiment of the present invention, after determining that the same stroke extracted from the character written by the user is a repeated stroke, the terminal device may send a prompt to the user to write a repeated stroke, where the prompt includes, but is not limited to, what kind of stroke the repeated stroke is and location information of the repeated stroke in the character written by the user. The prompt message may be sent out in the form of voice, pop-up window, or label, which is not limited herein.
The repeated strokes may refer to strokes that are re-modified after a user writes one stroke. For example, when the user writes the uppermost 'cross' of the 'king', the 'cross' is not correct for the first time, and modification optimization is performed on the 'cross' for the second time.
According to the embodiment of the invention, when the number of strokes of the user writing the character is different from the number of strokes of the corresponding standard character, the same strokes are extracted from the character written by the user, and whether the stroke orders of the extracted same strokes are adjacent and whether the same strokes are overlapped is detected, so that whether repeated characters exist in the character written by the user is detected, and the writing of the user is standardized.
Referring to fig. 2, which is a schematic view of an implementation flow of a method for determining repeated strokes provided in the second embodiment of the present invention, where the method is applied to a terminal device, as shown in the figure, the method may include the following steps:
in step S201, a character written by a user is acquired.
The step is the same as step S101, and reference may be made to the related description of step S101, which is not repeated herein.
Step S202, recognizing the characters written by the user to obtain standard characters matched with the characters written by the user.
The step is the same as step S102, and reference may be made to the related description of step S102, which is not repeated herein.
Step S203, respectively obtaining the stroke number of the user writing the character and the stroke number of the standard character.
The step is the same as step S103, and reference may be made to the related description of step S103, which is not described herein again.
Step S204, if the number of the strokes of the user writing the character is different from the number of the strokes of the standard character, extracting the same strokes from the character written by the user.
The step is the same as step S104, and reference may be made to the related description of step S104, which is not repeated herein.
Step S205, if the same strokes extracted from the characters written by the user are adjacent in stroke order and overlap, determining that the same strokes extracted from the characters written by the user are repeated strokes.
The step is the same as step S105, and reference may be made to the related description of step S105, which is not repeated herein.
And step S206, pushing the correct writing demonstration information of the repeated strokes to the user.
In the embodiment of the invention, the terminal equipment can push the demonstration information of the correct writing of the repeated strokes to the foreground for displaying, so that a user can conveniently check the correct writing process of the repeated strokes. Wherein the demonstration information of the correct writing of the repeated strokes may refer to a demonstration video of the correct writing of the repeated strokes.
The embodiment of the invention adds the correct writing demonstration information of the same stroke extracted from the character written by the user to the user on the basis of the first embodiment, thereby facilitating the user to check the correct writing process of the repeated strokes and improving the user experience.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
