1 is a block diagram showing the configuration of a user-customized color makeup printing medium providing apparatus according to an embodiment of the present invention, and FIG. 2 is a user-customized color makeup printing medium providing apparatus according to an embodiment of the present invention. An example implementation is shown.

The user-customized color makeup print media providing device 100 (hereinafter referred to as the device 100 ) includes a camera 110 , a display 120 , a printer module 130 , a print media providing module 140 , and a control unit 170 ). includes Additionally, the device 100 may further include a distance sensor 150 , a communication module 160 , a payment module 180 , and the like.

As in the example shown in FIG. 2 , the apparatus 100 for providing a print media for a user-customized color make-up may be implemented in the form of a kiosk device, but the present invention is not limited thereto, and may be implemented in other forms. In particular, as shown in the example shown in FIG. 11 , it can be implemented in the form of a smart terminal carried by a user.

The camera 110 is used as a means for photographing the user's face, and transmits the captured user's face image to the controller 170 . In addition, the camera 110 may be implemented in a form including two or more camera modules, such as a stereo camera, and may be utilized as a distance sensor 150 for measuring the distance from the device 100 to the user. The stereo camera allows two or more cameras to calculate a distance to an object through images respectively captured by the two or more cameras.

The display 120 is disposed on the front side of the device 100 to output a user interface. The user interface outputs the user's face received through the camera 110 and provides an interface screen 190 that allows the user to select a desired makeup target region and color.

For example, in a state in which the user interface is activated through the display 120 , the face of the user being photographed is displayed in real time through the camera 110 , and the outline of the face or the face is displayed through the face recognition or image recognition algorithm. After recognizing the outline of a major makeup target region, such as eyebrows, eyes, lips, and cheeks, candidate markers for displaying them may be generated and displayed. A user can easily select a makeup target part only by selecting a candidate marker for each makeup target part displayed on the user interface. In addition, the size of the makeup target part may be adjusted through a drag input or the like on the makeup target part on the user interface. For example, by adjusting the horizontal or vertical length of candidate markers displayed in an overlay form on the eyebrows or lips on the user's face image displayed through the user interface, the user can input size information about the makeup target area. can Similarly, the user may select a desired color for each makeup target portion through the user interface.

In this way, the device 100 may select one or more of the plurality of candidate makeup site candidate markers through the user interface, and receive a selection input of a size and a desired color for each makeup target site.

In addition, as shown in (b) of FIG. 2 , the makeup application screen is virtually displayed according to the information set by the user, so that it can be checked whether the input is according to the user's intention. In addition, even if all of the information you have entered is correctly entered, it is checked whether it is reflected harmoniously on your face as a whole, and shape change input to change the shape of the image to be printed, color correction input to change the color, and printing Various feedbacks such as a size correction input for adjusting the size of the target image are inputted.

In addition, through the user interface, it is possible to perform payment, etc. for a service for providing a print media for a user-customized color make-up.

The printer module 130 is a module for printing various color expression materials for color makeup on a printing medium, and in particular, a module for performing printing by an inkjet method. A plurality of ink cartridges each providing different colors are coupled to the printer module 130 . The printer module 130 finally performs printing according to the print command received from the control unit 170 . In particular, a printing operation is performed so that a user-customized color is expressed according to the color determined by the control unit 170. Since the operation of performing color printing in this way itself corresponds to the prior art, a detailed description thereof will be omitted.

The color expression material provided to the printer module 130 may be in the form of any one of solid, powder, liquid, gel, and gas. The color expression material may be composed of a single component material or a composition including a plurality of components, and may have its own color. For example, the color expression material may include all of a pigment, a dye, and a natural or artificial raw material exhibiting color, but the scope of the present invention is not limited thereto.

On the other hand, in the present invention, after the color cosmetics are printed on the print medium, the print medium is attached to the face so that the color cosmetics are applied to the face. It is either a liquid or a solid gel that allows good transfer from the medium to the face, skin, and body hair, or maintains a mixed state.

The print media providing module 140 stores a plurality of print media, supplies them to the printer module 130, and discharges the print media on which the cosmetics are printed in the printer module 130 to the outside of the device 100. Perform the action provided to the user.

In this case, the provided printing medium may be implemented in the form of a mask covering the entire face, as shown in FIG. 10 to be described later. Color cosmetics are printed on the eyebrows, eyelids, cheeks, and tufts, and makeup can be completed by covering and adhering the mask to the user's face.

Also, different from that shown in FIG. 10 , an individual printing medium cut in advance to correspond to the shape of each makeup target area may be provided.

The print medium providing module 140 selects one print medium from a set in which a plurality of print media are regularly gathered, provides the selected print medium to the printer module 130 , and discharges the completed print medium to the outside of the device 100 . Various actuators for the purpose, including a mechanical configuration such as a transport means.

The distance sensor 150 measures the distance between the device 100 and the user and transmits it to the controller 170 . In this way, the measured distance value is used to convert the size of the printed image of the makeup target area to match the size of the user's face.

As the distance sensor 150 , an ultrasonic sensor, an infrared sensor, a LiDAR sensor, a RADAR sensor, or a stereo camera sensor may be used.

Meanwhile, the distance between the device 100 and the user may be initially set to a preset value. That is, when the device 100 is installed, a marker indicating the user's optimal position is displayed on the floor in advance, and the distance between the device 100 and the corresponding marker is used as the reference distance, the distance of the distance sensor 150 . The distance between the device 100 and the user can be roughly estimated without a measurement process.

The communication module 160 supports data communication between various components included in the device 100 , and also supports data communication with other computing devices or servers existing outside the device 100 . For example, when payment is required through the payment module 180 , the communication module 160 supports data communication to enable authentication with various external payment servers.

In addition, the communication module 160 supports external data download, program update, etc. for the execution of the user-customized color make-up print media providing program executed by the control unit 170 .

The payment module 180 supports cost settlement for a user-customized color makeup print media providing service, and provides a cost settlement function based on various payment methods such as cash, credit card, and NFC payment method.

The controller 170 controls the operation of the camera 110 , the display 120 , the printer module 130 , the print medium providing module 140 , the distance sensor 150 , the communication module 160 , or the payment module 180 . do. The control unit 170 includes a memory and computing means such as a processor, executes a user-customized color makeup print media providing program stored in the memory, and provides a print medium on which user-customized color cosmetics are printed to the user.

The control unit 170 executes a user-customized color make-up printing medium providing program, photographs the user's face through the camera 110, extracts a feature area from the photographed user's face image, and the device 100 and the user The actual size of the feature region is calculated using the distance to and a measured size conversion constant defined by the ratio of the actual size of the feature region to the image size of the feature region is calculated. Then, the controller 170 receives the setting information on the makeup target part on the user's face image displayed through the user interface output through the display 120, and converts the actual size of the selected makeup target part into the image size. A printing condition is set by multiplying a constant, a printing condition is provided to the printer module 130 to perform a printing operation, and then a printing medium on which printing is completed is provided to the user.

First, a user's face is photographed through the camera 110 of the device 100, and a feature region is extracted from the photographed user's face image (S310).

In this case, the device 100 may guide the user to be spaced apart by a preset distance or guide the user to wait at a marker previously displayed in front of the device 100 . Through this, the face is photographed in a state in which the optimal reference distance between the device 100 and the user is secured.

Then, a feature region is extracted from the photographed face image.

4 exemplarily illustrates a process of extracting a feature region from a face image in a method of providing a print medium for user-customized color makeup according to an embodiment of the present invention.

Feature area extraction can be extracted through the process of deriving the edge portion through an image processing algorithm. The feature area (indicated by green dots) includes various areas such as the entire face outline, eye border, eyebrow border, and lip border. can be extracted. As such, the size value of the extracted feature region may be determined in units of pixels on the image. However, the size of each feature region on the image may be different from the actual size of each feature region. This is because the distance between the user and the device 100 may vary. Accordingly, in the present invention, even if the distance between the user and the device 100 is different, the actual size of each feature area can be calculated, and based on this, the makeup image printed on the print medium will be output in the same size as each feature area. handle it so that

Referring back to FIG. 3 , the actual size of the feature area is calculated ( S320 ).

Previously, the actual size of the feature region may be calculated using a preset distance between the device 100 and the user or a distance measured by the distance sensor 150 .

5 to 7 are diagrams for explaining the concept of converting the size of a print target image according to the size of the user's face in the apparatus for providing a print medium for a user-customized color make-up according to an embodiment of the present invention.

In the present invention, in order to provide a user-customized print medium, an operation of converting the size of the print target image to fit the size of the user's face is performed.

As described above, the distance between the device 100 and the user is a preset initial value, or the distance between the device 100 and the user is measured through the distance sensor 150 .

First, the process of calculating the actual size by using the preset initial value may calculate the actual size only by multiplying the preset ratio. That is, the size of the feature region on the image may be determined in the form of a pixel value, and the actual size of the feature region is calculated by multiplying each pixel-based size by a preset ratio.

Meanwhile, as shown in FIG. 5 , if the distance measured by the distance sensor 150 is used, the distance between the device 100 and the user (d), the focal length of the camera (f), and the size of the feature area on the image (r) Based on , the actual size R of the feature region may be calculated. That is, by multiplying the size (r) of the feature area on the image by the distance (d) between the device 100 and the user and dividing by the focal length (f) of the camera, the actual size (R) of the feature area can be calculated. . On the other hand, the size r of the feature region on the image is a pixel unit value and is determined by a value output to the image, and does not require measurement using a separate device.

As shown in FIG. 6 , this is based on a phenomenon in which the size of the photographed image changes as the distance between the same subject and the device 100 of the same size changes. Through this process, the actual feature area is You can check the size.

Meanwhile, another method for checking the actual size is shown in FIG. 7 .

When taking a picture, the device 100 guides the user to take a picture together with a reference object such as a credit card whose size is known, and may calculate the actual size using the guide.

That is, the actual size (E) of the feature region may be calculated based on the actual size value (M) of the reference object, the size (m) on the image of the reference object, and the size (e) of the feature region on the image. . That is, if the size (e) of the feature area on the image is multiplied by the actual size value (M) of the reference object and then divided by the size (m) on the image of the reference object, the actual size (E) of the feature area can be calculated. can For reference, FIG. 7 illustrates a process of calculating the actual size by selecting the eye size as a feature region.

Next, an actual size conversion constant defined by the ratio of the actual size of the feature region to the image size of the feature region is calculated ( S330 ).

As described above, this is to solve the problem that the size of each makeup target part specified on the user interface changes due to the difference in the distance between the device 100 and the user, and accordingly, the size of the image actually printed in the future changes. will be.

For example, it is assumed that the length of user A's eyebrows is measured as 300 pixels on the image through the above process, and the actual length of the eyebrows is calculated as 60 mm. In this case, the actual size conversion constant is determined to be 0.2 mm/pixel.

In the case of another user B, it is assumed that the length of the eyebrows is measured as 300 pixels on the image, and the actual length of the eyebrows is calculated as 50mm. In this case, the actual size conversion constant is determined to be 0.166 mm/pixel.

At this time, user A and user B have different eyebrow lengths of 60 mm and 50 mm, respectively, but the distance from the device is 300 mm and 200 mm, respectively, and shooting in different environments. . If printing is performed using only the size of the image as described above, a problem in that a makeup image of the same size is printed despite the actual eyebrow length is different. In order to solve this problem, in the present invention, the measured size conversion constant is calculated as before.

Next, the device 100 receives setting information on the makeup target site through the user interface provided on the display 120 (S340).

While the user's face being photographed through the camera 110 is displayed on the user interface in real time, candidate markers may be displayed for each makeup target area automatically generated through the user's face recognition or image recognition algorithm. In addition, the user may conveniently set the makeup target part by selecting one or more of the plurality of makeup target part candidate markers. In this case, eyebrows, eyes, lips, cheeks, etc. may be set as the makeup target part.

Meanwhile, as shown in FIG. 9 , one or more template images are prepared in advance for each makeup target region. In this case, a plurality of shapes of the template image may be provided for each part. For example, a template image for eyebrows may also be provided in various shapes, and the user may select a preferred template image among them.

Also, it is possible to adjust the size of the template image of the part to be made up on the user interface through a drag input or the like. For example, by adjusting the horizontal or vertical length of a template image indicating candidate markers displayed in an overlay form on eyebrows or lips on the user's face image displayed through the user interface, the user can determine the size of the makeup target area. You can enter information. The template image whose size is adjusted in this way is set as a printing condition after being multiplied by an actual size conversion constant as a size value on the image of the part to be made up. In addition, the user may select a desired color for each makeup target part through the user interface.

Through this process, the user, through the user interface, provides information on the makeup target part set by the user, the color for each makeup target part selected by the user, the shape of the template image selected by the user for each makeup target part, and the size of the template image You can virtually check the state of the transformation applied.

As shown in (b) of FIG. 2 , before printing is performed on a print medium, a pre-printing process is performed so that the user can check whether the information set by the user is input according to his/her own intention. In addition, even if all of the information you have entered is correctly entered, it is checked whether it is reflected harmoniously on your face as a whole, and shape change input to change the shape of the image to be printed, color correction input to change the color, and printing Various feedbacks such as a size correction input for adjusting the size of the target image are inputted.

Next, printing conditions are set by multiplying the image size of the selected makeup target area by the measured size conversion constant, and printing is performed on a print medium according to the printing conditions (S350).

As described above, the actual size conversion constant calculated in step S330 is multiplied by the size on the image of the makeup target area input in step 340 to provide a printing result that matches the actual size of the makeup target area.

On the other hand, there are cases where the print size conversion constant is different for each printer module. The print size conversion constant is defined by the ratio of the pixel length to the actual print length. For example, when an image of 100 pixels is input to the printer module, it may be set to be printed in 10 mm. In this case, the print size conversion constant becomes 10 pixel/mm.

In the example of User A above, if the actual eyebrow length is calculated to be 60 mm, multiplying this by a print size conversion constant, the final print condition is determined to be 600 pixels, and the print job is performed accordingly.

The print size conversion constant may be different depending on the printer module, and the controller 170 may store the print size conversion constant for each printer module and use it separately for each printer module.

As shown, each print target image may be printed on a mask-type printing medium. Alternatively, printing may be performed on individual print media that have been cut in advance to correspond to the shape of the part to be made-up.
