The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the application may be practiced without one or more of the specific details, or with other methods, units, modules, steps, etc. In other instances, well-known aspects have not been shown or described in detail to avoid obscuring aspects of the application.
In an exemplary embodiment of the present application, first, an electronic output system for a hand-drawn image is provided, as shown in fig. 1, where the electronic output system for a hand-drawn image in this embodiment includes a layer recognition module 110, a handwriting conversion module 120, and an output module 130, specifically:
the layer recognition module 110 is configured to perform layer division on the hand-drawn text according to handwriting attributes of the hand-drawn text in the output instruction.
In this embodiment, since the hand drawing text may include multiple handwriting attributes, in order to facilitate subsequent electronic output of the hand drawing text with different handwriting attributes, the hand drawing text is first divided into layers according to the handwriting attributes in the hand drawing text. The handwriting attribute comprises handwriting color, handwriting line width and/or handwriting line type, wherein the handwriting color is black, blue, red, yellow, red and other single colors or mixed colors formed by combining at least two colors; handwriting line types include straight lines, arcs, spiral lines, and the like. For example, if a handwritten signature of a party is black, dividing the handwritten signature into one layer; for another example, if a handwritten signature of a party includes black and blue, dividing the handwritten signature picture into two layers, corresponding to black and blue, respectively; for another example, if the principal wants to output an image, dividing the image into a plurality of layers according to each handwriting attribute in the image, wherein the layers correspond to different handwriting attributes respectively; that is, the present application can be applied to the output of text or images.
In some possible embodiments, the layer identification module 110 may be located on a host computer (e.g., a client with a hand-drawing or picture importing function), and may be a web page, an APP applet or public platform, etc. In some possible embodiments, the layer identification module 110 may be disposed on a server, and of course, the layer identification module 110 may be disposed on other positions, such as an output component (drawing robot), according to actual needs, and the present application includes, but is not limited to, the disposing position of the layer identification module 110.
The handwriting conversion module 120 is configured to convert the handwriting in each layer into a stroke path, and convert the stroke path into a computer language.
In this embodiment, the handwriting conversion module may include a node recognition unit, a node connection unit, and a conversion unit, where the node recognition unit is configured to recognize handwriting in the layer as a plurality of nodes; the node connection unit is used for connecting the plurality of nodes obtained by the node identification unit to form a stroke path; the conversion unit is used for converting the stroke path into a computer language.
Specifically, the node recognition unit and the node connection unit may be an automatic unit or may be a unit that can be independently operated by a user, so that handwriting in the handwriting drawing can be recognized as a plurality of nodes manually or automatically, and then the recognized plurality of nodes are connected to form a stroke path; the manual mode may manually outline nodes on the hand-drawn graph by using drawing software, which may be Photoshop, autoCAD, adobe image or Paper 53, to form a stroke path. The automatic mode can automatically outline the nodes on the hand-painted pictures and texts to form stroke paths by adopting a character track recognition algorithm. The recognition algorithm of the text track includes, but is not limited to, iDT algorithm or CSDN algorithm, and the corresponding text track recognition algorithm can be selected according to actual needs, which is not particularly limited in the present application.
In some possible implementations, the handwriting conversion module 120 may be located at a host computer (client), which may be a web page, an APP applet or public platform, or the like. In some possible embodiments, the handwriting conversion module 120 may be disposed on a server, and of course, the handwriting conversion module 120 may be disposed on other positions according to actual needs, such as an output component (e.g. a drawing robot), etc., which includes but is not limited to the disposed position of the handwriting conversion module 120.
Further, referring to fig. 2, the electronic output system of the hand-drawn text may further include an adjustment module 140 for adjusting nodes on the stroke path and/or adjusting node connection lines on the stroke path. When the node or node connecting line in the stroke path obtained by the handwriting conversion module 120 is found to be different from the original hand-drawn text, the real-time adjustment can be performed through the adjustment module 140, so that the lines of the hand-drawn text are smoother and are closer to the text which is drawn by the principal in a pen, the accuracy of the stroke path conversion is further ensured, of course, the adjustment module 140 can also automatically adjust the node or node connecting line according to the identification result, and can also perform manual adjustment by a user.
Of course, as with the layer recognition module 110 and the handwriting conversion module 120, the adjustment module 140 may be located on a host computer (such as a client), or may be disposed on a server or an output component, which is not limited in this disclosure.
And the output module 130 is used for sequentially carrying out electronic drawing output of each layer according to a computer language after the output instruction passes the security verification.
In this embodiment, after the output command is ensured to pass the security verification, the output module 130 performs the drawing output of the corresponding layer with the drawing medium as the medium, that is, when the output module 130 performs the electronic drawing output of the hand drawing text according to the computer language, it is required to switch to different drawing mediums according to the different layers.
For example, if the text in the hand-drawn text includes two colors (such as blue and black), the hand-drawn text is divided into two layers corresponding to blue and black, and when the output module 130 outputs the electronic hand-drawn text, the electronic hand-drawn text is first switched to a blue pen for writing, and after the blue corresponding layer is written, the electronic hand-drawn text is written by switching to a black pen, so that the electronic hand-drawn text is completed. Based on this, the output module 130 selects the drawing medium corresponding to each layer based on the computer language to perform drawing, and ensures that each layer obtained uses the similarity with the original hand-drawn image on the drawing medium.
In some possible embodiments, the handwriting conversion module 120 and the output module 130 may be located in a lower computer (for example, a writing device), and when the output of the hand-drawn text is required, the lower computer converts the stroke path corresponding to the hand-drawn text into a computer language, and performs the electronic drawing output according to the computer language. Based on the above, the lower computer has the function of converting the stroke path into the computer language, so when the hand-drawn image and text needing to be output electronically exists, the lower computer can flexibly convert the corresponding stroke path into the computer language, thereby enabling the use of the lower computer to be more flexible and easy to control.
It should be noted that, the conversion from the stroke path to the computer language may also be completed at an upper computer (such as a client) or a server, and the output module 130 directly performs the electronic drawing output of each layer based on the obtained computer language, which is not limited in particular by the present application.
Further, referring to fig. 3, the electronic output system of the hand-drawn text may further include a security verification module 150 for confirming the operator's use authority through security verification of the output instruction.
In this embodiment, the user right of the operator may be determined by outputting the user identification information included in the instruction, where the user identification information may be registration information that the user has, such as a number, a character, other characters or code information of a combination of a number, a character and other characters, or code information including a device number of the corresponding output component, or fingerprint information, face image identification information, and the like collected during user registration. Further, if the security verification module 150 determines that the output command fails to pass the security verification, for example, if the signature output this time differs greatly from the signature handwriting stored last time, the user needs to perform the security verification again, for example, the manner of inputting the user identification information again, the verification code, and the like.
In some possible embodiments, the security verification module 150 may be disposed on a host computer (such as a client), or may be disposed on a server or an output component, but it is required to ensure that the output command is securely verified before the output module performs the electronic drawing output.
In addition, referring to fig. 4, the electronic output system of the hand-drawn image and text may further include a storage module 160, configured to store the hand-drawn image and text, and the stroke path corresponding to the hand-drawn image and text for browsing and downloading by the user, where, of course, when the same hand-drawn image and text needs to be repeatedly output again, the electronic output system of the hand-drawn image and text may also be directly invoked, thereby improving the electronic output efficiency of the hand-drawn image and text.
When the stroke path of the hand-drawn picture and text is stored, encryption can be performed to ensure the safety of the hand-drawn picture and text and prevent misuse and counterfeiting, and the hand-drawn picture and text can be realized by setting fingerprints, short message verification or starting passwords, facial recognition and other modes; in addition, the stroke path of the hand-drawn image and text is saved, and when necessary, the stroke path is converted into a computer language at any time through the handwriting conversion module 120, so that the device for deploying the handwriting conversion module is more convenient and rapid to use and high in flexibility.
In some possible embodiments, the storage module 160 may be disposed in a server, and each time the obtained hand-drawn text and the corresponding stroke path are stored in the storage module 160 in the server, so as to facilitate multiple uses of the stroke path corresponding to the same hand-drawn text.
Further, with continued reference to fig. 4, the electronic output system of the hand-drawn text may further include a main control module 170, configured to issue an output instruction of the hand-drawn text, and display an output progress of the electronic drawing of the output module; and before issuing the output instruction of the hand-drawn image, comparing the current hand-drawn image with the hand-drawn image pre-stored in the storage module 160, and calling a target stroke path corresponding to the current hand-drawn image from the storage module 160 according to the comparison result.
In some possible embodiments, the main control module 170 may be located at a client, such as a web page, an APP applet or a public platform, etc., and the output progress of the electronic drawing of the output module 130 may also be displayed at the client by the main control module 170, so as to monitor the working dynamics of the output module 130 at any time.
Further, the main control module 170 can be linked with the layer recognition module 110, the handwriting conversion module 120 and the output module 130 at any time and any place, the handwriting path of the corresponding hand-drawn image can be called out by directly inputting the hand-drawn image or the picture of the hand-drawn image into the main control module 170, and the output module 130 can output the electronic hand-drawn image at any time and any place, wherein each module can be linked in any conventional networking mode (wired or wireless networking), and the application does not have special requirements on the hand-drawn image.
Further, the main control module 170 may further include a registration unit for registering an account, and the electronic output system of the hand-drawn text is started by inputting the account, so that remote control of the system can be realized, including sharing the hand-drawn text, sharing a path corresponding to the hand-drawn text, storing the hand-drawn text in the storage module 160, and the like, and meanwhile, each user is ensured to have an account, and the security of electronic output is ensured. The account registration can be set according to the actual encryption requirement, for example, only by single-password encryption or multiple-password double-encryption mode, and the like.
In addition, the main control module 170 may further include a charging unit, and may call the hand-drawn text uploaded by the other person through the payment function.
In summary, the electronic output system of hand-drawn pictures and texts can provide the picture and text output result which has extremely high similarity with the handwriting of the principal or is completely the same with the handwriting of the principal under the condition that the principal is not on site and the principal needs to sign or draw, so that the transaction processing efficiency is prevented from being influenced by the fact that the principal is not on site, manpower and material resources are saved, and when the electronic output of the hand-drawn pictures and texts is carried out, the hand-drawn pictures and texts can be divided into a plurality of picture layers to be output, thereby realizing the output of pictures and texts with various colors and formats, and in addition, the function of converting stroke paths into computer languages through the handwriting conversion module enables the flexibility of the output equipment provided with the handwriting conversion module to be higher, and any hand-drawn pictures and texts can be output anytime and anywhere; in addition, the user permission is ensured through the safety verification module, and the phenomenon that the hand-drawn image and text is misappropriated and output is avoided.
According to an aspect of the present application, there is also provided an electronic output method for hand-drawing graphics, as shown in fig. 5, the method comprising the steps of:
step S510, dividing the hand-drawn text into layers according to the handwriting attribute of the hand-drawn text in the output instruction.
In this embodiment, the handwriting attribute includes handwriting color, handwriting line width, and/or handwriting line type; the handwriting attribute comprises handwriting color and/or handwriting line type, wherein the handwriting color is black, blue, red, yellow, red and other single colors or mixed colors formed by combining at least two colors; handwriting line types include straight lines, arcs, spiral lines, and the like.
Dividing the hand drawing text into different layers according to different handwriting colors and/or handwriting line types. For example, if a handwritten signature of a party includes black and blue, the handwritten signature picture is divided into two layers, corresponding to black and blue, respectively.
Step S520, converting the handwriting in each divided layer into stroke paths respectively, and converting the stroke paths into computer languages.
In this embodiment, handwriting in the layer is identified as a plurality of nodes, and the resulting plurality of nodes are connected to form a stroke path, which is converted into a computer language.
Optionally, handwriting in the layer is identified as a plurality of nodes, which can be automatically identified or manually identified, wherein a manual mode can manually outline nodes on the hand-drawn image by using drawing software to form a stroke path, and the drawing software can be Photoshop, autoCAD, adobe image or Paper 53. The automatic mode can automatically outline the nodes on the hand-painted pictures and texts to form stroke paths by adopting a character track recognition algorithm. The recognition algorithm of the text track includes, but is not limited to, iDT algorithm or CSDN algorithm, and the corresponding text track recognition algorithm can be selected according to actual needs, which is not particularly limited in the present application.
Furthermore, when the node or node connecting line in the obtained stroke path is found to be different from the original hand-drawn text, the node or node connecting line can be manually adjusted to enable the lines of the hand-drawn text to be smoother and closer to the text which is personally drawn by a person, the accuracy of the conversion of the stroke path is further ensured, and of course, the node or node connecting line can be automatically adjusted according to the identification result.
Step S530, sequentially carrying out electronic drawing output of each layer according to the computer language.
In this embodiment, the stroke path may be converted into a computer language corresponding to the hand-drawn text by engraving control software such as Grbl Controller software or Artcam software.
In this embodiment, the drawing medium corresponding to each layer may be selected based on a computer language, and the drawing medium is used as a medium to perform drawing output of the corresponding layer.
For example, if the text in the hand-drawn text includes two colors (such as blue and black), the hand-drawn text is divided into two layers corresponding to blue and black respectively, and when outputting the electronic hand-drawn text, the hand-drawn text is first switched to a blue pen for writing, and after the blue corresponding layer is written, the hand-drawn text is switched to a black pen for writing, so that the electronic writing of the whole hand-drawn text is completed. Based on the above, the drawing medium corresponding to each layer can be selected based on the computer language to carry out drawing, and the similarity between each obtained layer and the original hand drawing image can be ensured on the drawing medium.
It should be noted that before sequentially performing drawing and writing output of each layer according to the computer language, the method may further include: and carrying out safety verification on the output instruction to confirm that the operator has the use authority.
Specifically, the user permission of the operator can be judged by outputting the user identification information contained in the instruction, wherein the user identification information can be registration information of the user, such as number, character, other character or code information of combination of number, character and other character, or code information containing the corresponding equipment number of the output component, or fingerprint information collected during user registration, face image identification information and the like. Further, if it is determined that the output command fails to pass the security verification, for example, if the difference between the signature output this time and the signature handwriting stored last time is large, the user needs to perform the security verification again, for example, the manner of inputting the user identification information again and the verification code again.
Furthermore, the hand-drawn pictures and texts and the stroke paths corresponding to the hand-drawn pictures and texts can be compared and stored for browsing and downloading by a user, and of course, when the same hand-drawn pictures and texts need to be repeatedly output again, the same hand-drawn pictures and texts can be directly called, so that the output efficiency of the hand-drawn pictures and texts is improved.
When the stroke path of the hand-drawn picture and text is stored, encryption can be carried out to ensure the safety of the hand-drawn picture and text and prevent misuse and falsification, and the hand-drawn picture and text can be realized by setting fingerprints, short message verification or starting passwords, facial recognition and other modes.
Further, an output instruction of the hand-drawn image and text can be issued through a visual interface of a client (such as a web end and an APP end), and the output progress of the hand-drawn image and text is displayed; in addition, when a hand-drawn picture is obtained, the current hand-drawn picture and the pre-stored hand-drawn picture can be compared at first, and a target stroke path corresponding to the current hand-drawn picture is called according to the comparison result, so that repeated work is avoided, and the output efficiency of the electronic hand-drawn picture is improved.
