Description

Latte Art Printing Method by Line Method {LATTEART PRINT METHOD OF LINE TYPE}

The present invention relates to a latte art printing method, and more particularly, to a latte art printing method of a line method for mechanically drawing a latte art of barista level or more through a line method.

Ancient primitive people engrave letters or drawings on stones or shells, and since the invention of paper, they began to paint on paper, which became art. In recent years, painting is done in a variety of ways, and people in the 21st century call coffee and call it "work."

Latte art refers to the drawing of coffee on the coffee using the milk foam. It is a word created by combining the art of art with the Italian latte, which means milk, and the foam and milk produced when making a cafe latte. It can be seen as the art of creating beautiful roses, hair, leaves, etc. Beautifully illustrated coffee made by skilled baristas magically, Latte Art lets you enjoy coffee with your eyes as well as your tongue and nose.

Baristas are Italians that mean in-bar makers, which are distinguished from bartenders who make cocktails, and only refer to experts who make coffee. Baristas choose the best beans and make the most of the coffee machine to maximize their taste. I work to make coffee to give. At the same time, they also perform creative roles such as latte art, and even baristas must make latte art with a sense acquired through long experience and concentration, such as the amount of foam and milk / force control / art sense.

On the other hand, a technology for automating such a latte art to be drawn through a printer has been developed, the base technology for automating such a latte art is in the printer. The printer is an output device that prints the information processed by the computer in a form that can be seen by humans. It is divided into impact type and non-impact type according to the printing method, and classified into serial printer, line printer, page printer, etc. according to the output unit. do.

There have been attempts to develop prototypes for latte art printers using these printer-based technologies. However, the conventional latte art printers cannot print precisely the latte art because the injection control method is not accurate, so it is difficult to draw sophisticated latte art. There was this.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and an object of the present invention is a latte art printing method of a line method that enables an automated drawing of a sophisticated barista level latte art using a printer. To provide.

Latte art printing method of the line method according to the present invention for achieving the above object, the step of inputting an image to be drawn on the coffee surface to the computer, the step of binarizing the image input to the computer to the latte art printer, And performing X, Y matching of the binarized image in a latte art printer and outputting the latte art on the coffee surface in a line manner.

Step of inputting the image to the computer It is preferable to transfer the image possessed by the client or the image taken by the mobile phone to the computer through the external memory or the Bluetooth communication function of the mobile phone to input the image, the image input to the computer by the client I icon image can be added and edited.

In addition, the resolution is changed so that the image input to the computer can be output on the coffee surface, the shape is changed according to the shape of the container containing the coffee, and then binarized through the image processing binarization process.

The latte art printer performs X and Y matching on the binarized image by 12-level dots, and then prints the image in a line manner by adjusting the ejection of the cartridge according to a correction algorithm. It is preferable to print the image in a line manner according to the injection control of the cartridge which moves both the X axis and the Y axis by the stamping motor and outputs 12 nozzles at a time.

The latte art printing method of the line method according to the present invention enables the user to create a latte art by precisely spraying the image transmitted from the computer onto the coffee by the spray control method according to a correction algorithm, thereby creating a sophisticated barista-level sophisticated latte art. It has the effect of drawing.

In addition, the present invention can draw a rapid and sophisticated latte art through a line-type latte art printing method has the effect of enabling the commercialization and popularization of latte art.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall flowchart illustrating a latte art printing process of a line method according to an embodiment of the present invention. 2A is a conceptual diagram illustrating a process of transmitting a picture selected by a client to a computer for latte art printing according to an embodiment of the present invention, and FIG. 2B is a conceptual diagram illustrating a process of editing a picture selected by a client. 2C is a flowchart illustrating a process of binarizing a picture selected by a client.

As shown in Figure 1, the latte art printing process according to the present invention is largely carried out through a three-step process. First, the "Image Acquisition" process of obtaining an image to be output from the outside (S100), the 'Image Processing' process (S200) of changing the size of the image to be printed and the output form (S200), and finally the latte art printer for image output It proceeds to the "LAP Control" process (S300) to control the X / Y-axis motor and the cartridge.

In order for the Latte Art Printer (LAP) to output an image to a latte, an image to be output is required. In the 'Image Acquisition' process (S100), the client selects an image to be output. As shown in FIG. 2A, the client selects an image, such as a photograph already possessed, or an image taken directly on the site through a mobile phone, and then uses an external memory (USB) or a Bluetooth communication function of the mobile phone. Interface (UI) is transmitted to the computer (PC) installed.

The image sent to the computer may be used as is, but the client may add a text or icon image over the selected image, as shown in FIG. 2B.

Once the client has edited the image for output, the edited image is changed in image form so that it can be output on the coffee surface. As shown in Figure 2c, after changing the resolution (252 * 168) that can output the size of the image on the coffee surface in the original image, change the square-shaped image to a round shape to match the coffee shape, and use image processing binarization To change the image form to one color. The changed image is changed into a form that can be stored in the memory (EEPROM) provided in the Latte Art Printer (100).

Figure 3a is a perspective view of a latte art printer according to an embodiment of the present invention, Figure 3b is a plan view of a latte art printer.

As shown in Figs. 3A and 3B, the Latte Art Printer 100 according to the present invention includes two stepping motors (X Axis Moter and Y) for drawing an image in 2D on a coffee surface. Using the Axis Moter (120) 130, the cartridge 110 is configured to move both the X and Y axis, wherein the nozzle of the cartridge 110 is 12 at a time It is configured to output two nozzles. In addition, when outputting an image, the cartridge 110 does not draw one pixel, but moves one line like a picture to shorten the time for drawing an image.

When a person grabbed a pencil and passed a square, the experiment showed how much difference there is in the gap. As the width of the square gets wider, the error rate increases by more than 2.5 times the square area and speed. The size of a regular square mug is 6.5 × 6.5 cm. To reduce the error rate, the printer should spray the printer's line speed proportional powder at the exact X and Y positions at 0.03 second intervals. This is referred to as a 'correction algorithm' in the present invention.

The formula of the correction algorithm according to the present invention is as follows.

CaltechTime = (ThisTime-LastTime)

CaltechTime = ((CaltechTime + DoubleTime) / 2)

Vxp = (Xp-Xpp) / (DoubleTime-LastTime)

Vyp = (Yp-Ypp) / (DoubleTime-LastTime)

Vxo = (Xo-Xp) / (ThisTime-LastTime) 'current speed

Vyo = (Yo-Yp) / (ThisTime-LastTime) 'current speed

Ax = (Vxo-Vxp) / CaltechTime 'acceleration

Ay = (Vyo-Vyp) / CaltechTime 'acceleration

tD = 0.06 'Magic Number (Delay, Delay Time)

xx = Xo + (Vxo * tD + (1/2) * Ax * tD * tD) 'Predicted X value

yy = Yo + (Vyo * tD + (1/2) * Ay * tD * tD) 'Predicted Y value

According to the correction algorithm, the cartridge 110 of the latte art printer 100 can accurately draw the latte art by spraying the powder accurately in proportion to the line speed of the printer at the designated X and Y positions. That is, after the X and Y matching is performed on the binarized image stored in the latte art printer 100 by 12-level dots, the injection of the cartridge 110 outputting 12 nozzles at a time is controlled according to the correction algorithm. The image is printed in a line manner.

As described above, the latte art printing method of the line method according to the present invention performs a process of importing, editing, and binarizing an image selected by a client, and then finely drawing the binarized image through a correction algorithm.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications within the equivalent range of the technical spirit of the present invention and the claims to be described below by those skilled in the art to which the present invention pertains. And of course modifications can be made.
