3 is a flow chart showing a drawing method according to an embodiment of the present invention. Further, FIG. 4A is a detailed conceptual diagram of a preprocessing process according to an embodiment of the present invention. In addition, FIG. 4B is an exemplary view of the result of a pre-processing process according to an embodiment of the present invention.

The computing device 100 may recognize the handwriting of a character from the input character image 401 (310). Recognizing the handwriting of a character includes converting the inputted character image 401 into a black and white image expressed only in black and white, and recognizing the handwriting of the character from a black and white image as one of the preprocessing steps. Can include.

In addition, the gray scale step 402 refers to a step of converting the input text image 401 into a black and white image expressed only in black and white. The gray scale step 402 may convert an image having a chromatic color to an image having an achromatic color. This step only works for images with chromatic colors and can be omitted for images with only achromatic colors.

More specifically, the step of converting the input character image 401 to a black and white image includes a brightness value of each pixel constituting the achromatic character image and a threshold value that is a preset threshold brightness value when the input character image is an achromatic character image. Comparing the values 403 and converting the color of each pixel to black or white. In addition, when the input character image 401 is a chromatic character image, the step of converting the chromatic character image to an achromatic character image and the brightness value of each pixel constituting the converted achromatic character image and a threshold value that is a preset threshold brightness value Comparing (403) may include converting the color of each pixel into black or white. That is, the steps to be performed vary depending on whether the input image 401 is an achromatic image or a chromatic image. In particular, when the input text image 401 is an achromatic color, since the step of converting the chromatic text image to an achromatic text image is omitted, the amount of calculation is reduced, so that processing can be performed at a high speed. For example, when the original image 451 is a chromatic color image, the gray scale step 402 to easily recognize the handwriting of a character may result in an image such as 452 of FIG. 4B. In addition, when the original image 451 is an achromatic image, an image such as 452 of FIG. 4B may be recognized from the input image 401 by omitting the gray scale step 402. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

In addition, the step of recognizing the handwriting of a character in a black and white image may further include a Gaussian blur (404) step. More specifically, the Gaussian blur step 404 is one of the pre-processing processes. After the step of the gray scale 402, the image that stands out clearly is converted to blur, thereby attenuating noise and You can use the image more effectively. In other words, an image in which noise is attenuated may be obtained through Gaussian blur.

In addition, the step of recognizing the handwriting of a character in a black and white image may include a Canny edge step 405 and a step 406 of determining a pixel width. More specifically, the Canny edge step 405 is a step of extracting a boundary line of a character image. In addition, the step 406 of determining the pixel width is a step of determining the pixel width of the text image after extracting the boundary line of the text image. The width of the pixel of the text image from which the boundary line is extracted is determined by referring to the stroke length and width of the previously input characters. Through the above steps, the form of letters is established. For example, the image after the Gaussian blur step 404 and the Canny edge step 405 may be an image as shown in 454 of FIG. 4B, and the step 406 for determining the pixel width The shape of the image may be an image such as 456 of FIG. 4B. The text image after passing through the above steps becomes a form of text that we commonly recognize. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

Further, the computing device 100 may generate a font 409 corresponding thereto based on the recognized handwriting (320). In addition, the method may further include generating information on a path on which the pen of the drawing device moves based on the handwriting recognized in parallel with the step of generating a corresponding font. The step of generating a font corresponding to the recognized handwriting based on the recognized handwriting may include a thinning step 407 and a pruning step 408 as another partial step of the preprocessing process.

More specifically, the thinning step 407 is a step for drawing after passing through the above steps, and is a step of making the width of the pixel 1. The above step is to create a path through which the pen of the drawing device moves. For example, in an image such as 456 of FIG. 4B, an image such as 457 of FIG. 4B may be obtained by passing through a thinning process 407 in which a pixel width is 1 as a step for creating a drawing path of a drawing device. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

In addition, the pruning step 408 is a step for removing noise pixels around the boundary line of the character image generated during the thinning step 407. The pruning step 408 refers to a step of removing noise pixels around a boundary line of a character image generated in the thinning step. In particular, the pruning step 408 may serve to enhance the completeness of the text image by removing noise around the boundary line of the text image. By increasing the completeness of the text image, an effect close to that of handwritten can be obtained. For example, in the process of passing through the thinning step 407, it can be seen that noise is finely generated around a character boundary, as shown in the image 457 of FIG. 4B. When drawing in the above-described state, the drawing apparatus 200 may perform drawing by recognizing noise around the boundary line as text. In that case, the object of the present invention to obtain an effect from what was written by hand may be halved. To solve this problem, through the pruning step 408, an image such as 458 of FIG. 4B is obtained, and characters with higher degree of completion can be drawn. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

In addition, the computing device 100 may convert the input character into the generated font 409 (330). For example, after inputting a character to be created using an existing document writing program, the font 409 generated in the above step may be selected and converted in the same manner as the font replacement format. As a result of converting to the generated font 409, an image such as 520 of FIG. 5 may be obtained. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

In addition, the computing device 100 may transmit the converted character to the micro computing board (MCB) 210 of the drawing device 200 (340 ). More specifically, the computing device 100 may transmit the expected output image 520 displayed on the display device 250 to the microcomputing board (MCB) 210 of the drawing device 200. The micro computing board (MCB) 210 may track the drawing line of the transmitted expected output image 520.

In addition, the micro-computing board (MCB) 210 may draw the converted character transmitted from the computing device 100 (350). More specifically, the microcomputing board (MCB) 210 may transmit a signal of the converted character to the microcontroller unit (MCU) 220. The microcontroller unit (MCU) 220 may operate the motor 230 with the received signal. For example, when the motor 230 receives a signal from the microcontroller unit (MCU) 220 and draws the expected output image 520, a clean image such as 530 of FIG. 5 may be obtained. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

In addition, the computing device 100 may add a step of displaying the converted character on the display 250 after passing through the step of converting to the generated font. The displaying on the display 250 is a step for checking whether the converted document is a result expected by the user before drawing with the drawing device 200. The user may check the expected output result 520 displayed on the device of the display 250 and input a correction command. The computing device 100 may further include determining whether a correction command has been received from the outside for the text output to the display 250 device.

More specifically, this is a process for confirming the content that the user outputs before drawing with the drawing device 200. The computing device 100 may further include determining whether a correction command has been received from the outside for the text output to the display 250 device. When the correction command is received in the determining step, the step of correcting the character output on the display 250 according to the correction command may be further included. That is, the step of fine-tuning the image of the character of the expected output image 520 displayed on the display 250 may be further included. By adding this step, you can make the desired output image more complete. For example, if the document desired by the user is'its team calligrapher', the computing device 100 may display the converted character using the generated font 409 on the display 250 in the form of an expected output image 520. I can. Here, the user may fine-tune, such as correcting some characters or adjusting the size of some characters by viewing the image of the expected output image 520. When drawing with the drawing device after the above fine adjustment step is performed, the image 530 of FIG. 5 may be obtained. Image 530 of FIG. 5 is the same image as created by an actual user, and is a result meeting the object of the present invention. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

5 is an exemplary view showing results of actual use of a drawing system according to an embodiment of the present invention. For example, when a text image 510 is input to the computing device 100, the computing device 100 recognizes the text image 510 through the aforementioned pre-processing process and generates a specific font 409 corresponding thereto. I can. The computing device 100 may display the expected output data 520 on the display 250 when the character to be output is converted into the generated font 409. When the user inputs an approval signal to the expected output data 520, the computing device 100 may send a signal to the drawing device 200 to perform a drawing operation to obtain an output result 530. The above example is only an example for describing the present disclosure, and the present disclosure is not limited thereto.

As described above, when using a conventional plotter bot or tablet PC, only fonts stored in the computer could be used. The use of existing cursive writing can also achieve some of the effects written by hand, but it is definitely different from documents written by hand. On the other hand, the output according to the disclosed embodiments of the present invention can obtain an effect of delivering the printed output manually written by the user.
