Description

The present invention relates to a method and apparatus for manufacturing a personalized mask pack,

The present invention relates to a personalized mask pack manufacturing method and apparatus therefor.

Existing disposable mask packs do not accurately reflect the position and area of different eyes, nose, and mouth for each person. Since the mask pack is made of a flexible material such as paper, the pack can be brought into contact with the eyes, nose, and mouth by pulling a part by hand when worn. However, when one side of the mask pack is pulled, the other side is rotated. Therefore, the effect of the mask pack can be expected in a portion where the skin is less flexed, such as a cheek or a forehead portion. However, The effect of the mask pack can not be properly transmitted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing the overall configuration of a mask system according to the present invention. FIG.

Referring to FIG. 1, the information storage and design apparatus 110 receives two-dimensional or three-dimensional face images of each user from at least one user terminal 100, stores the personalized face images, The position or the length of the face portion of the user, etc., and design a personalized mask pack based on the position or length. For example, the information storage and design device 110 designs a mask pack to match personalized facial features.

The manufacture of the mask pack and the addition of the serum can be realized through the three-dimensional printer 120. For example, the three-dimensional printer 120 may include a nozzle for spraying a cosmetic liquid and a laser or a blade for cutting. The three-dimensional printer 120 can cut a plurality of mask packs at once using a laser. According to an embodiment, the 3D printer 120 may not be in the same space as the information storage and design apparatus 110. For example, the information storage and design apparatus 110 can convert a file for designing a mask pack into an IGES (Initial Graphics Exchanges Specification) standard file and transmit it to an individual or an enterprise having the 3D printer. In this case, mask packs can be dispersed and manufactured through a plurality of individuals or corporations, which can reduce the investment cost of production facilities.

The information storage and design apparatus 110 may perform bidirectional communication with the user terminal 100. [ Through bi-directional communication, the user of the user terminal 100 can be provided with personalized beauty and skin care consultation, recommended management, etc. from an expert.

The information storage and design apparatus 110 stores and manages information of users who have requested the personalized mask pack production in a database. For example, the information storage and design apparatus 110 may receive facial images of each person and cosmetic treatment requirements (e.g., requirements for cosmetic effects, cosmetic essence, etc.) from the user terminal 100, . The information storage and design apparatus 110 can use the Big Data Analysis technique to identify face information and beauty treatment preference information by country, age, and race, and to utilize it in new product development, effect analysis, and trend analysis. This is worth the enterprise's high-value information assets.

The three-dimensional printer 120 of the present embodiment may include various types of two-dimensional printers for printing on a two-dimensional plane, as well as a printer for producing a general three-dimensional shape without depending on its name.

Although the present embodiment shows one three-dimensional printer 120 for performing cutting and adding a serum, the apparatus for cutting and the apparatus for adding a serum may be implemented as separate apparatuses. At this time, the apparatus for cutting can be implemented not only as a three-dimensional printer but also as a conventional various kinds of cutting apparatuses.

The user terminal 100 includes various types of terminals including a camera function, a three-dimensional scanner function, and a wired / wireless communication function, for example, a smart phone, a tablet PC, and a computer. Here, the camera function or the three-dimensional scanner function may be embedded or externally mounted on the user terminal 100. [

FIGS. 2 to 5 are views illustrating an example of a method for acquiring a face image through a user terminal according to the present invention.

2 and 3, various types of guide lines 200 and 300 for photographing a face image may be displayed on the screen of the user terminal 100. [ For example, the user terminal can display a guide line 200 for front face image pickup and a guide line 300 for lateral face image pickup on the screen, respectively.

The guide lines 200 and 300 may be in various forms that can indicate a shooting distance, a direction, and the like when photographing a face image. For example, the guide line 200 for photographing a frontal face image in FIG. 2 may include a guide line indicating at least one of eye, nose, and mouth in addition to a simple round shape.

Referring to FIGS. 4 and 5, an example of face photographing using the guide lines 200 and 300 of FIGS. 2 and 3 is shown. The user photographs his or her front face 400 and the side face 500 on the guide line displayed on the screen of the user terminal.

The face image captured by the user terminal 100 may be a two-dimensional image of a still image or a moving image photographed through a general camera, or a three-dimensional image photographed through a three-dimensional camera or a three-dimensional scanner. The user terminal 100 can receive a three-dimensional image captured by using a separate scanner or a three-dimensional camera for capturing a three-dimensional image, or an external three-dimensional scanner or a three-dimensional camera. Here, the two-dimensional image means an image having coordinate values in the x-y plane, and the three-dimensional image means an image having spatial coordinate values of x-y-z.

FIG. 6 is a view showing a configuration of a user terminal for photographing a face image for manufacturing a mask pack according to an embodiment of the present invention.

6, the user terminal 600 includes a guide display unit 610, a photographing unit 620, an editing unit 630, a beauty request setting unit 640, and a transmitting unit 650. The configuration of the user terminal 600 may be implemented as a smartphone application. For example, the user terminal can download the application prepared for the present embodiment from an external server and install it, thereby implementing the configuration of FIG.

The guide display unit 610 displays a guide line for photographing the face image in FIGS. 2 to 5 on the screen of the user terminal 600. The guide line 200 for the front face image of FIG. 2 and the guide line 300 for the side face image of FIG. 3 may be sequentially displayed.

The photographing unit 620 photographs a two-dimensional or three-dimensional face image. For example, when the user terminal 600 has a built-in camera or a built-in camera, the photographing unit 620 controls the camera to take two-dimensional face images of front and side. As another example, if the 3D scanner is built in or enclosed in the user terminal, the photographing unit 620 captures the 3D face image by controlling the 3D scanner.

The editing unit 630 provides a tool that can modify the face image photographed by the photographing unit 620 to fit the guide line. For example, the editing unit 630 may reduce or enlarge the photographed face image to fit the guide line when the face image photographed by the photographing unit 620 is larger or smaller than the guide line, If they do not match, provide various tools to rotate the face image. The editing unit 630 may be omitted according to the embodiment. Or the editing unit 630 may be implemented in an information storage and design apparatus.

The beauty request setting unit 640 sets the beauty request setting unit 640 to allow the user to set a beauty treatment request (e.g., whitening, pore management, moisturizing, etc.) And the like): wrinkle reduction, etc.). For example, the beauty request setting unit 640 can receive beauty treatment requirements that show different cosmetic effects for various parts of the face such as eyes, nose, mouth, forehead, and the like. The beauty request setting unit 640 displays a captured face image or a virtual face image on the screen of the user terminal so that the user can easily input a beauty treatment requirement for each specific area using the face image displayed on the screen . The beauty request setting unit 640 may be omitted according to the embodiment.

The transmitting unit 650 transmits the two-dimensional or three-dimensional face image photographed by the photographing unit 620 and the beauty treatment request set by the beauty request setting unit 640 to the information storing and designing apparatus 110.

FIG. 7 is a flowchart illustrating an example of a method of photographing a face image for manufacturing a mask pack according to the present invention.

Referring to FIG. 7, the user terminal displays a guide line on the screen so that the face image can be captured in a predetermined size and direction (S700). The user captures the face with the guide line displayed on the screen of the user terminal (S710). The user terminal may receive a cosmetic treatment request relating to a serum or the like to be added to the mask pack from the user (S720). The user terminal can select one serum from the user or select different serum for each part such as eyes, nose, and mouth. According to the embodiment, the user terminal may omit the process of receiving the beauty treatment request (S720). The user terminal transmits the photographed face image and the cosmetic treatment requirements to the information storage and design apparatus (S730).

FIG. 8 is a diagram showing a configuration of an embodiment of an information storage and design apparatus according to the present invention.

8, the information storing and designing apparatus 110 includes a receiving unit 800, a database storing unit 810, a holding unit 820, and a designing unit 830.

The receiving unit 800 receives a two-dimensional or three-dimensional face image from a user terminal or the like. Here, the two-dimensional face image may include at least one face front image and at least one face side image. The receiving unit 800 does not necessarily receive the facial image from the user terminal, but can receive the two-dimensional or three-dimensional facial image in various paths. According to the embodiment, the receiving unit may further receive information on cosmetic processing requirements for each part of the mask pack from the user terminal.

The database storage unit stores database images of facial images received by the receiving unit 800, beauty treatment requirements, and the like. By analyzing the information stored in the database, it can be used for new product development, effect analysis, and trend analysis by grasping face information, beauty treatment preference information by country, age, and race.

Since the mask pack has a two-dimensional plane shape and a face has a three-dimensional solid shape, it is possible to use a mask pack such that when the mask pack is worn on the face, the position and area of various parts of the actual face (e.g., eyes, nose, mouth, forehead, The position of eyes, nose, mouth, etc. should be cut.

For this, the grasping unit 820 grasps various characteristic values related to the position or length of the face parts such as eyes, nose, mouth, etc. for cutting the two-dimensional mask pack based on the face image received by the receiving unit 800 . An example of characteristic values is shown in Fig. These characteristic values are different from person to person.

Since the three-dimensional face image includes spatial information of (x, y, z), it is possible to accurately grasp the various characteristic values of FIG. 9 for the two-dimensional mask pack design using various conventional three-dimensional image processing algorithms. For example, the determination unit 820 can analyze the three-dimensional facial image to grasp the actual width when the nose region is spread in two dimensions. The determining unit 820 detects various characteristic values of the face from the three-dimensional face image, corrects the characteristic values to fit the two-dimensional mask pack (minus correction), and grasps the position or the length when the respective parts are spread on the plane . Here, the negative correction means that the correction value is applied to the x, y, z information by removing the z value.

However, since the two-dimensional face (x, y) photographs do not include spatial information, in order to fit the mask pack to the three-dimensional face, the various characteristic values shown in FIG. Here, the positive correction means that the correction value is applied to the x, y information by reflecting the z value.

Therefore, the present embodiment provides a method for grasping various characteristic values for mask pack cutting from a two-dimensional face image that can be easily obtained through a camera or the like of a conventional smart phone.

The grasping unit 820 grasps the positions or lengths of the face parts such as eyes, nose, mouth, forehead, and ball based on the frontal face image. Since the front face image is a two-dimensional projection of the three-dimensional face, the height information is not reflected, and the position or the length of various face parts recognized in the front face image is determined by the position and length Lt; / RTI > For example, looking at the nose, the length of the nose obtained from the frontal face image is shorter than the actual length when the nose is two-dimensionally expanded because the nose is not reflected in the height information because it is an image projected in two dimensions .

In order to correct the error of the position or the length, the side face image is used in this embodiment. That is, the grasping unit 820 corrects the positions or lengths of the face parts for cutting using the inclination or height information of various facial parts such as eyes, nose, and mouth, which are grasped through the side face images. For example, when looking at the eye, the length of the tail detected in the frontal face image is shorter than the length of the tail of the two-dimensional plane because the height information of the tail is not reflected. Therefore, the grasping unit 820 grasps the position of the eye for cutting by correcting the length of the fingernail observed in the frontal face image by using the slope or height information of the fingernail region grasped through the lateral face image. Such correction will be described in detail again with reference to FIG.

The designing unit 830 designes a two-dimensional mask pack based on the positional values or the lengths of characteristics of various parts of the face grasped by the grasping unit 820.

9 and 10 are views showing an example of characteristic values and correction values for designing a personalized mask pack according to the present invention.

9 and 10, the information storing and designing apparatus includes an eye position and a lateral length (a), a distance between foreheads (b) from a two-dimensional or three-dimensional face image for producing a personalized mask pack 900, The distance between the nose and under the nose, the distance between the nose and the nose, the distance between the nose and the mouth, the width of the mouth, the length of the fingers, The distance between the under eye and the lower border of the mask, the width of the nose (k), and the face front length (l).

(A), the distance between the eyes (b), the width (k) of the nose, the mouth (k) of the mouth, The length (e), the face front length (l), and the length (g) of the face side of the face. The y-axis direction information includes a distance (c) between the under-eye and the under-nose, a distance (d) between the under-nose and the under-mouth, a distance (i) between the upper and lower sides of the mask, And the vertical length (f) of the human being.

Since the mask pack is in the form of a two-dimensional plane, it can not reflect the z-axis direction of the face. Therefore, in order to facilitate attachment of the two-dimensional mask pack to the three-dimensional face, a mask pack having a predetermined length (for example, Add a cal line (that is, a cut line). An example of a knife line is shown in Fig.

The information storage and design apparatus expands the outline 910 of the face, which is grasped through the front face image or the like, using the characteristic values to reflect the lateral length g of the face, and the position and length of the eye (a) Adjust the eyes and mouth according to position and length (e), and design the nose to match the nose width (k).

The characteristic values of the present embodiment are examples for helping understanding of the present invention, and some of the characteristic values may be used or other characteristic values may be used according to the embodiment.

11 is a view showing an example of a positive correction method of characteristic values for manufacturing a mask pack according to the present invention.

Referring to FIG. 11, the information storage and design apparatus grasps the slope degree (.theta.) Or height (h) information of each part from the face image. For example, the information storage and design apparatus can model the three-dimensional images based on the images taken at different angles with respect to the same object as the frontal image and the side image of the face, thereby determining the inclination and the like of each portion. At this time, the information storage and design apparatus can convert the three-dimensional curvature of the face into a convex shape or a concave simple form and calculate the inclination ([theta]) for easy calculation. Since there are various conventional methods of three-dimensionally modeling based on a plurality of two-dimensional images, detailed description thereof will be omitted. As another example, the information storage and design device can determine the height information of the nose that appears on the side image of the face, such as the nose.

The information storing and designing apparatus recognizes the length information when the inclination or the height information of each part of the face is recognized and based on the inclination or the height information, the part is spread in two dimensions. For example, if the three-dimensional curvature 1100 shown in FIG. 11 is a simplified form for the half portion of the nose, the width of the half of the nose in the frontal image of the face is l, . Therefore, the information storage and designing device determines the inclination of the nose or the height information of the nose and then calculates the characteristic value (2 * (1 + 1 (1 / cos? -1)) of the actual width 9) is obtained. Correction of the various characteristic values shown in Fig. 9 is performed by this method.

12 is a view showing an example of a method of adding a curved line when cutting a mask pack according to the present invention.

As shown in FIG. 9, since the mask pack is implemented on a two-dimensional plane, it can not be satisfactorily attached to a face having a three-dimensional curvature. Therefore, it is possible to add certain curved lines 1200, 1210, 1220, and 1230 to the eyes, nose, mouth, and face contour so as to be adhered to the three-dimensional curvature. In this case, it is preferable that the length of the curl line is determined in proportion to the magnitude of the characteristic value in FIG. In other words, if the size of the nose is small, the length of the nose line is also made small accordingly. If the size of the nose is large, the length of the nose line is made longer.

FIG. 13 is a flowchart illustrating a method of storing and designing information according to an embodiment of the present invention.

Referring to FIG. 13, the information storage and design apparatus receives a two-dimensional face image (S1300). The information storage and design apparatus stores the received two-dimensional face image in the database (S1310), analyzes it, and analyzes the characteristic values related to the positions and sizes of the face parts such as eyes, nose, and mouth (S1320). Then, the identified characteristic value is subjected to positive correction (S1330), and a two-dimensional mask pack is designed using a three-dimensional printer or the like based on this value (S1340).

FIG. 14 is a flow chart of an embodiment of a method for manufacturing a two-dimensional mask pack from three-dimensional face data according to the present invention.

14, the information storage and design apparatus stores 3D face data (S1400), stores it in a database (S1410), and stores characteristic values related to positions or lengths of face parts such as eyes, nose, and mouth (S1420). Then, the information storage and design apparatus performs negative correction (S1430) to design a two-dimensional mask pack based on the three-dimensional face image.

15 is a view showing an embodiment of a three-dimensional printer for manufacturing a mask pack according to the present invention.

Referring to FIG. 15, a plurality of three-dimensional printers 1500, 1510, 1520, and 1530 are disposed on a conveyor belt 1540 of a sort. The first three-dimensional printer 1500 cuts the two-dimensional mask pack based on the characteristic values for the cutting as shown in FIG. 9 according to the control of the information storing and designing apparatus. The cut mask pack is moved to the position of the next second three-dimensional printer 1510 through the conveyor belt 1540. The second three-dimensional printer 1510 adds the serum A to a specific portion of the mask pack under the control of the information storage and design apparatus. Thereafter, the mask pack sequentially moves to the three-dimensional printers 1520 and 1530 at the next position, and the serum of each part is added. In this way, different cosmetic liquids can be added to the mask pack as shown in Fig.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium.
