Abstract
Description
Technical Field
[0001] This invention relates to a 3D-printed face-shaped mask, and more particularly to a 3D-printed face-shaped mask formed in the same shape as a human face, thereby providing protection against dust and infectious bacteria. Background Technology
[0002] Recently, as air pollution has become more severe, more and more people are suffering from respiratory diseases such as bronchitis and lung diseases. For example, in the case of rhinitis, damage to the nasal mucosa caused by immune system disorders, imbalances in body temperature, organ dysfunction, and toxins can lead to symptoms such as nasal congestion, sneezing, runny nose, headache, and decreased sense of smell.
[0003] In addition, COVID-19 infection, a respiratory disease caused by the novel coronavirus, occurs when droplets from an infected person penetrate the respiratory system or the mucous membranes of the eyes, nose, and mouth. After an incubation period of 2 to 14 days, respiratory symptoms such as high fever, cough, or difficulty breathing, as well as pneumonia symptoms, appear.
[0004] Therefore, people are actively seeking various solutions to prevent and eliminate the aforementioned novel coronavirus and other infectious diseases. Face masks are hailed as the most basic and effective means of protecting humans from air pollution, including the novel coronavirus.
[0005] Generally, masks are made of fibrous materials such as cotton and are worn to cover the lower part of the face. However, these ordinary masks are stuffy to wear because they cover the wearer's face, leading to resistance to wearing them in regions like Europe and the Americas where the face is considered a part of one's identity. Therefore, there is an urgent need to develop new types of masks that can solve these problems. Summary of the Invention
[0006] The problem the invention aims to solve
[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a 3D-printed face-shaped mask that is formed in the same shape as a human face, thereby preventing dust and infection of infectious bacteria.
[0008] Problem Solving Methods
[0009] To achieve the above objectives, according to one aspect of the present invention, a face-shaped mask is provided. The face-shaped mask includes: a mask body corresponding to the lower face shape of a user's face, with the user's lower face shape marked on its exterior; at least one filter portion installed on at least one side of the mask body; and ear loops for securing the mask body to the user's ears. The mask body is 3D printed based on a 3D mask model corresponding to the lower face shape of a face including the user's nose and mouth; at least one of the filter portions is installed corresponding to at least one of the lower part of the nose and the mouth.
[0010] The aforementioned filter section includes a first filter section; a first filter section mounting portion for mounting the first filter section is formed at least at a position corresponding to the nostrils on the aforementioned mask body. The aforementioned first filter section is detachable from the aforementioned first filter section mounting portion. The aforementioned first filter section and the aforementioned mask body are joined to the aforementioned first filter section mounting portion by any of the following methods: interference fit, screw connection, and sliding connection.
[0011] The first filter section includes: a right nostril filter section corresponding to the right nostril of the mask body; and a left nostril filter section corresponding to the left nostril of the mask body. The mask body includes: a right nostril filter section mounting section for mounting the right nostril filter section; and a left nostril filter section mounting section for mounting the left nostril filter section.
[0012] The aforementioned filter section further includes a second filter section; a second filter section mounting portion for mounting the second filter section is formed at a position corresponding to the opening on the aforementioned mask body. The aforementioned second filter section can be detached from the aforementioned second filter section mounting portion.
[0013] The aforementioned second filter section and the aforementioned mask body are connected to the aforementioned first filter section mounting section by any of the following connection methods: interference fit, screw connection, Velcro connection, snap-fit connection, and sliding connection.
[0014] The aforementioned at least one filter unit includes a filter installed on the user's face in a breathing-related part to provide ventilation and to block at least one of droplets, yellow sand, smoke, toxic gases, smog, and viruses from entering the human body.
[0015] The aforementioned 3D mask model is generated by receiving multiple 2D images of the face being used and transforming these multiple 2D images into 3D images.
[0016] The process of receiving the aforementioned multiple 2D images includes: receiving access information from the SNS server corresponding to the user's account from the user terminal, and collecting multiple 2D images, including the user's face, from the SNS server corresponding to the user's account.
[0017] The aforementioned multiple 2D images are 2D images of the user's face received from the user terminal, including images captured during or stored on the user terminal. The multiple 2D images include a frontal image, a left side image, and a right side image of the user.
[0018] The process of generating the 3D model includes: extracting multiple feature points corresponding to the user's face from the received multiple 2D images; transforming the reference 3D face model into a 3D face model corresponding to the user's face based on the extracted multiple feature points; and separating the lower face shape portion corresponding to the transformed 3D face model of the user's face.
[0019] The aforementioned face-shaped mask also includes a snug fit that is formed along the inner and outer periphery of the mask body, and fits snugly against the user's face when the user wears the mask; through the snug fit, a space is formed between the mask body and the user's face when the mask is worn.
[0020] Invention Effects
[0021] As described above, according to the present invention, a 3D-printed face-shaped mask is provided, formed in the same shape as a human face, thereby providing dust protection and preventing infection from infectious agents. Because the face-shaped mask has a shape and image corresponding to the user's face, it can be worn aesthetically without any discomfort. Furthermore, according to the present invention, visually seamless filters are formed in breathing-related areas such as the nostrils and mouth, and these filters are replaceable, thus providing an aesthetically pleasing and economical mask.

[0043] This invention can be modified and has various embodiments, with specific embodiments illustrated in the accompanying drawings and described in detail. However, this invention is not intended to be limited to a particular mode of implementation, but rather to include all modifications, equivalents, and even substitutions that fall within the scope of the invention's ideas and techniques.

The purpose of these terms is to distinguish one structure from another. For example, without exceeding the scope of this invention, a first structure can be named a second structure, and similarly, a second structure can be named a first structure. "And / or" indicates a combination of multiple related descriptions or one of multiple related descriptions.
[0045] The terminology used in this application is merely illustrative of specific embodiments and not intended to limit the invention. Where there is no explicit indication of singularity in the context, the singular designation includes the meaning of plural. In this application, terms such as "comprising" or "possessing" indicate the presence of the features, numbers, steps, actions, structures, components, or combinations thereof described in the specification, rather than precluding the existence or additional possibilities of one or more other features, numbers, steps, actions, structures, components, or combinations thereof.
[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the process of describing the present invention, for ease of understanding, the same reference numerals are used for the same components in the drawings, and repeated descriptions of the same components are omitted.
[0047] Figure 1 This is a block diagram illustrating the configuration of a system for manufacturing a 3D-printed face-shaped mask according to a preferred embodiment of the present invention.
[0048] like Figure 1 As shown, the system may include a server 100, a 3D printer 30, a mask production unit 40, etc. The server 100 may be implemented based on one or more computer terminals. The server 100 can be linked with the 3D printer 30 and the mask production unit 40.
[0049] Furthermore, server 100 can be connected to user terminal 10, SNS (Social Networking Service) server 20, etc., via a communication network. For example, user terminal 10 can be a user's mobile phone or PC. SNS server 20 can be a server that operates and manages users' SNS accounts. SNS can be, for example, Instagram, Facebook, Twitter, TikTok, Kakao Page, etc.
[0050] Server 100 receives multiple 2D images of a user's face from user terminal 10 or SNS server 20, and can generate a 3D mask model corresponding to the lower part of the user's face through 3D modeling based on the received multiple 2D images. Here, the 3D mask model may include at least the lower part of the user's nose and mouth.
[0051] Figure 2 For illustrative purposes Figure 1 A detailed block diagram of the server 100 is shown below. Figure 2 As shown, the server 100 may include: a receiving unit 110, which receives multiple 2D images of a user's face; and a mask model generation unit 120, which generates a 3D mask model corresponding to the lower face shape of the user's face based on the received multiple 2D images through 3D modeling.
[0052] 3D printer 30 can perform 3D printing based on a 3D mask model generated by server 100 to produce a mask body corresponding to the lower face shape of the user. Here, the mask body corresponds to the lower face shape of the user, thus covering the lower face according to the curvature of the user's face, and an image of the user's lower face is printed on the outside, i.e., the front of the mask. Therefore, even when the user is wearing a mask, it appears as if the user is not wearing one. The mask body can be made of a plastic material that maintains its shape while possessing a certain degree of elasticity.
[0053] Furthermore, according to another embodiment of the present invention, the mask body covers the lower part of the user's face in a curve that conforms to the shape of the user's face, and can be made of a transparent material to correspond to the shape of the lower part of the user's face. For example, the mask body can be a transparent plastic material that is elastic while maintaining its shape. In this case, if the user wears the mask, the mask has the same curve as the user's face, perfectly matching the lower part of the user's face, and because it is transparent, the user's face is visible, thus appearing as if the user is not wearing a mask.
[0054] The mask production unit 40 can produce a mask corresponding to the user by attaching at least one filter and ear loops to the mask body. The mask production unit 40 may, for example, include production equipment for attaching the filter and ear loops.
[0055] Figure 3 For illustrative purposes Figure 1 The flowchart shown illustrates the operation process of a 3D-printed face-shaped mask manufacturing system, and describes a face-shaped mask manufacturing method according to a preferred embodiment of the present invention.
[0056] Please see Figures 1 to 3 First, the server 100 receives multiple 2D images of the user's face from at least one of the user terminal 10 and the SNS server 20 (step S1).
[0057] For example, server 100 can receive a 2D image of a user's face captured by user terminal 10. For example, server 100 can receive a 2D image of the user's face captured or captured and stored on user terminal 10.
[0058] To this end, server 100 may invite user terminal 10 to capture a 2D image of the user's face. When inviting the 2D image, server 100 indicates to the user interface that the user terminal 10 can choose to activate the camera for live shooting or select a photo pre-saved on the user terminal 10. Depending on the user's choice, the camera that can be used for live shooting will be activated or a preview list of photos pre-saved on the user terminal 10 will be displayed.
[0059] For example, server 100 can also receive 2D images of a user's face from SNS server 20, which manages the user's SNS account. For example, server 100 can receive access information from user terminal 10 to the SNS server 20 corresponding to the user's account, thereby allowing the SNS server 20 corresponding to the user's account to collect multiple 2D images including the user's face. That is, server 100 collects photos posted by the user on Instagram, Facebook, Twitter, KakaoStory, etc.
[0060] Next, server 100 can generate a 3D mask model corresponding to the lower part of the user's face based on the received plurality of 2D images through 3D modeling (step S2). The 3D mask model may include at least the parts related to the user's breathing, such as the lower part of the nose including the nostrils and the mouth. The plurality of 2D images may include a frontal image, a left side image, and a right side image of the user.
[0061] Figure 4 For detailed explanation Figure 3 The flowchart shown is a process for generating a 3D mask model. Figure 4 The action can be performed by the mask model generation unit 120 of server 100.
[0062] like Figure 4 As shown, firstly, server 100 can extract multiple feature points corresponding to the user's face from the received multiple 2D images (step S11). For example, server 100 can extract multiple feature points corresponding to the user's face by analyzing the user's frontal image, left side image, right side image, etc.
[0063] Next, based on the extracted feature points, the server 100 can transform the reference 3D face model into a 3D face model corresponding to the user's face (step S12). Therefore, the server 100 can generate a 3D face model corresponding to the user's face.
[0064] Then, server 100 can generate a 3D mask model corresponding to the lower face shape of the user's face from the 3D face model corresponding to the transformation (step S13). The 3D mask model can be the part of the mask covering in the user's 3D face model. For example, the 3D mask model can correspond to at least the parts of the 3D face model related to the user's breathing, such as the lower part of the nose including the nostrils and the lower face part of the mouth.
[0065] Please refer to it again. Figure 3After generating the 3D mask model, the 3D printer 30 can generate the mask body corresponding to the lower face shape of the user's face based on the generated 3D mask model (step S3).
[0066] The 3D printer 30 generates a mask body that corresponds to the lower face shape of the user. For example, the mask body has the same shape as the lower face of the user, so that when the mask is worn, it can completely fit and cover the lower face of the user. In addition, an image of the user's lower face can be printed on the front of the mask body. Therefore, even when the user is wearing a mask, it appears as if the user is not wearing a mask. The mask body can be made of a plastic material that has a certain degree of elasticity while maintaining its shape.
[0067] In another embodiment of the invention, the mask body may be formed of a transparent material. For example, the mask body has a shape that is the same as the lower face shape of the user, so that when the mask is worn, it can completely fit the lower face of the user and cover the lower face of the user's face. Moreover, because it is transparent, the lower face of the user can be exposed to the outside, so that it is as if the user is not wearing a mask.
[0068] Subsequently, the mask production unit 40 produces a mask corresponding to the user by attaching at least one filter and ear loops to the mask body (step S4). The mask production unit 40 may, for example, include production equipment for attaching the filter and ear loops.
[0069] The shape and composition of the aforementioned face-shaped mask are described in detail below.
[0070] Figure 5 A perspective view of the main body of a mask to roughly represent the shape of a face.
[0071] like Figure 5 As shown, the shape of the mask body 200 corresponds to the lower face shape of the user, and an image of the user's lower face can be marked on the front. The mask body 200 may include at least the parts related to the user's breathing, such as the lower part 210 of the nose including the nostrils and the mouth part 220.
[0072] On at least one side of the mask body 200, a filter mounting portion is formed for mounting at least one filter portion. For example, the at least one filter mounting portion may be a breathing-related part, such as the lower part 210 of the nose and the mouth part 220. In addition, on the other side of the mask body, ear loops for securing to the user's ears are formed or attached.
[0073] The filter section includes a portion of the mask related to the user's breathing to ensure breathability and prevent at least one of droplets, sand, smoke, toxic gases, smog, and viruses from entering the body. It is mounted on a filter section mounting section. The filter section is detachably mounted on the filter section mounting section, allowing for replacement.
[0074] The following is a detailed description of the installation structure of various filter sections for face-shaped masks.
[0075] Figure 6 This is a perspective view illustrating the mounting structure of a first filter portion formed on the lower part of the nose of a face-shaped mask according to an embodiment of the present invention.
[0076] like Figure 6 As shown, first filter mounting portions 210a and 210b are formed at the positions of the nostrils on the lower part 210 of the nose of the mask body 200. The first filter mounting portions 210a and 210b may include a right nostril filter mounting portion 210a corresponding to the right nostril and a left nostril filter mounting portion 210b corresponding to the left nostril. The right nostril filter mounting portion 210a and the left nostril filter mounting portion 210b are cylindrical sections formed at a certain height at the positions of the right and left nostrils on the lower end 210 of the nose of the mask body 200, respectively, with a through hole formed in the center.
[0077] The right nostril filter section 310a can be detachably installed on the right nostril filter section mounting section 210a. The right nostril filter section 310a may include a connecting section 314a, a hook section 316a, and a filter 210a.
[0078] The connecting portion 314a is formed as a cylinder that inserts into the through hole of the right nostril filter mounting portion 210a. The outer peripheral surface of the connecting portion 314a can be inserted into the through hole of the right nostril filter mounting portion 210a in an interference fit manner. The connecting portion 314a has a through hole for air circulation at its center. The hook portion 316a extends from the end of the connecting portion 314a and has a diameter larger than that of the connecting portion 314a. The through hole of the connecting portion 314a extends the hook portion 316a, which can form an air passage that enables air communication through the connecting portion 314a and the hook portion 316a. The hook portion 316a prevents the right nostril filter portion 310a from detaching from the outside, such as the front of the mask, when it is inserted into the right nostril filter mounting portion 210a, and facilitates the removal of the filter portion 310a when it is replaced.
[0079] The filter 312a is located on one side of an air passage formed by a through hole in the center of the aforementioned joint 314a and hook-on portion 316a, and air flowing through the air passage formed by the through hole will definitely pass through the filter 312a. The filter 312a is breathable and can block at least one of droplets, yellow sand, smoke, toxic gases, smog, and viruses from entering the human body.
[0080] The left nostril filter section 310b also has the same function as the right nostril filter section 310b described above, and the left nostril filter section 310b can be detachably installed on the left nostril filter section mounting section 210b. The left nostril filter section 310b may include a connecting part 314b, a hook part 316b, and a filter 312b.
[0081] The connecting portion 314b is formed as a cylinder that inserts into the through hole of the left nostril filter mounting portion 210b. The outer peripheral surface of the connecting portion 314b can be inserted into the through hole of the left nostril filter mounting portion 210b in an interference fit manner. The connecting portion 314b has a through hole for air circulation at its center. The hook portion 316b extends from the end of the connecting portion 314b and has a diameter larger than that of the connecting portion 314b. The through hole of the connecting portion 314b can be extended to the hook portion 316b to form an air passage through which air can flow through the connecting portion 314b and the hook portion 316b. The hook portion 314b prevents the left nostril filter portion 310b from detaching from the outside, such as the front of a mask, when inserted into the left nostril filter mounting portion 210b, and facilitates the removal of the filter portion 310b during replacement.
[0082] The filter 312b is located on one side of an air passage formed by a through hole in the center of the connecting portion 314b and the hanging portion 316b, and air flowing through the air passage formed by the through hole will definitely pass through the filter 312b. The filter 312b is breathable and can block at least one of droplets, yellow sand, smoke, toxic gases, smog and viruses from entering the human body.
[0083] Figure 7 To indicate in Figure 6 The diagram shows the state in which the right nostril filter mounting part 210a and the left nostril filter mounting part 210b are installed, and the diagram shows the lower part 210 of the nose of the mask when viewed from below in the wearing state.
[0084] like Figure 7As shown, by inserting the right nostril filter 310a and the left nostril filter 310b into the right nostril filter mounting portion 210a and the left nostril filter mounting portion 210b at the lower part 210 of the nose of the face-shaped mask, from the point of view of airflow, the filter 312a of the right nostril filter 310a and the filter 312b of the left nostril filter 310b are exposed to the outside.
[0085] Figure 8 This is a perspective view used to illustrate the mounting structure of a first filter portion formed on the lower part of the nose of a face-shaped mask according to another embodiment of the present invention, showing a schematic diagram of the structure for mounting the first filter portion based on a screw structure.
[0086] like Figure 8 As shown, a thread is formed in the through hole of the right nostril filter portion 410a, and a thread is formed on the outer peripheral surface of the connecting portion 514a of the right nostril filter portion 510a that engages with the thread of the through hole of the right nostril filter portion 410a. Therefore, the right nostril filter portion 510a can be screwed onto the right nostril filter mounting portion 410a. In addition, the hook portion 516a of the right nostril filter portion 510a has multiple grooves to facilitate turning the screw when screwed on.
[0087] Figure 9 This is a perspective view used to illustrate the mounting structure of a first filter portion formed on the lower part of the nose of a face-shaped mask according to another embodiment of the present invention, showing a structural schematic diagram of the first filter portion formed as a single unit.
[0088] like Figure 9 As shown, a first filter mounting portion 610 is formed at the lower part of the nose of the face-shaped mask. The first filter mounting portion 610 is an elliptical cylinder with a certain height (i.e., a cylinder with an elliptical cross-section), and a through hole is formed in the center.
[0089] The first filter section 710, detachably attached to the first filter section mounting section 610, has a convex cylindrical connecting portion formed to be inserted into a through hole of the first nostril filter section mounting section 610. The outer peripheral surface of the connecting portion can be inserted into the through hole of the first filter section mounting section in an interference fit manner. The connecting portion has two through holes for air circulation, and two filters 710a and 710b, corresponding to the right nostril and the left nostril, are provided in the through holes. As described above, when a face-shaped mask has one first filter section 710, it is not necessary to replace the filters corresponding to the two nostrils separately; the filter section 710 can be replaced all at once, thus making replacement easy.
[0090] Figure 10This is a perspective view for illustrating the mounting structure of the second filter portion formed on the mouth portion of a face-shaped mask according to an embodiment of the present invention.
[0091] like Figure 10 As shown, a second filter mounting portion 810 is formed at a position corresponding to the mouth portion 220 of the mask body. The second filter mounting portion 810 is a cylinder of a certain height, with a through hole formed in its center. At least a portion of the through hole can be exposed to the front of the mask body. In the mouth portion 220 of the mask body, the portion 812 that exposes the through hole is covered. For example, if the mouth portion 220 of the mask body is marked with an image of a slightly open mouth, the mouth portion 814 is covered, and in the open mouth portion, the portion other than the portion exposing the through hole is covered, for example, if it is an image of a natural mouth, an image of teeth may be marked.
[0092] The second filter section 910 can be detachably mounted to the second filter section mounting section 810, and may include a connecting part 914, a hook part 916, and a filter 912. The connecting part 914 is formed as a cylinder that inserts into the through hole of the left nostril filter section mounting section 810. The outer peripheral surface of the connecting part 914 can be inserted into the through hole of the left nostril filter section mounting section 810 in an interference fit manner. The connecting part 914 has a through hole for air circulation at its center.
[0093] The connecting portion 916 extends from the end of the connecting portion 914 and has a diameter larger than that of the connecting portion 914. The connecting portion 916 extends from the through hole of the connecting portion 914, forming an air passage through which air is communicated between the connecting portion 914 and the connecting portion 916. The connecting portion 914 prevents the second filter portion 910 from disengaging to the outside when inserted into the second filter portion mounting portion 810, making it easy to remove the second filter portion 910.
[0094] The filter 912 is located on one side of an air passage formed by a through hole in the center of the aforementioned joint 914 and hook-on portion 916. From the viewpoint of airflow, it is exposed to the outside, and the air flowing through the air passage formed by the through hole will definitely pass through the filter 912. The filter 912 is breathable and can block at least one of droplets, yellow sand, smoke, toxic gases, smog, and viruses from entering the human body.
[0095] Figure 11 To indicate Figure 10 This is a schematic diagram showing the state in which the second filter section 910 is installed on the second filter section mounting section 810.
[0096] like Figure 11As shown, by inserting the second filter portion 910 into the second filter portion mounting portion 810 formed in the mouth portion 220 of the face-shaped mask, from the viewpoint of airflow, at least a portion of the filter 912 having a through hole in the second filter portion 910 is exposed to the outside. In the mouth portion 220 of the mask body, the portion except for the portion exposing the filter 912 is covered. For example, the mouth portion 220 of the mask body is marked with an image of a slightly open mouth, and the portion marking the lip image is covered. In the portion marking the open mouth image, the remaining portion except for the portion exposing the through hole is covered. For example, for an image of a natural mouth, an image of teeth may be marked.
[0097] In addition, the aforementioned references Figures 6 to 11 The described detachable connection between the filter section and the filter section mounting section is an embodiment using an interference fit or a screw connection. However, according to other embodiments of the present invention, there may be various forms of connection between the filter section and the filter section mounting section, such as a Velcro connection, a sliding connection, or a snap-fit connection.
[0098] Figure 12 An oblique view showing the shape of a face mask with ear loops attached. (Example) Figure 12 As shown, ear loops 1100 for securing the mask 2000 to the user's ears can be installed at both ends of the mask body 200.
[0099] In addition, on the inner surface of the mask body 200 (i.e. the surface adjacent to the user's face), a fitting part is formed along the outer peripheral surface so that it fits snugly against the user's face when the user wears the mask 2000.
[0100] Figure 13 This is a cross-sectional view used to illustrate the fitting portion formed on the inner surface of the mask body 200.
[0101] like Figure 13 As shown, a snug fit 1200 is formed at the edge of the mask body 200. Through this snug fit 1200, when the mask is worn, the mask body 200 is separated from the user's face UF at a certain distance, forming a space 1220 between the mask body 200 and the user's face UF. This space 1220 prevents obstruction when the user speaks or makes facial expressions.
[0102] In addition, the fitting part 1200 is made of a flexible material, which improves the fit of the UF to the user's face, thereby preventing air from circulating in parts other than the filter while wearing the mask, thus improving the protective effect of the mask.
[0103] Figure 14 This is a perspective view illustrating the state of a user wearing a face-shaped mask according to an embodiment of the present invention.
[0104] like Figure 14 As shown, the face-shaped mask 2000 has a shape identical to the lower part of the user's face, allowing it to completely fit and cover the lower part of the user's face when worn. Furthermore, an image of the user's lower face is printed on the front of the mask body, thus creating the appearance that the user is not wearing a mask even when wearing it. From an airflow perspective, filters 312a, 312b, and 912 are exposed to the outside at the nostrils and mouth area below the nose of the face-shaped mask, allowing the user to breathe safely through the filters.
[0105] Figure 15 This is a perspective view used to illustrate the state of a user wearing a face-shaped mask according to another embodiment of the present invention.
[0106] like Figure 15 As shown, according to another embodiment of the present invention, the mask body 200' may be formed of a transparent material. For example, the mask body 200' has a shape identical to the lower part of the user's face, so that when wearing the mask, it can completely fit snugly against the lower part of the user's face, covering the lower part of the user's face, and because it is transparent, the lower part of the user's face can be exposed to the outside, thus appearing as if the user is not wearing a mask. In this embodiment, the mask's fitting portion, filter mounting portion, filter portion, etc., may be formed of a transparent material.
[0107] Figure 16 This is a block diagram illustrating the system structure of a method for manufacturing a face mask according to another embodiment of the present invention.
[0108] like Figure 16 As shown, the system may include interconnected servers 2100 and printers 2030, etc. Server 2100 may be implemented based on one or more computer terminals.
[0109] Furthermore, server 2100 can be linked with user terminal 2010, SNS (Social Networking Service) server 2020, etc., via a communication network. For example, user terminal 2010 can be a user's mobile phone or PC. SNS server 2020 can be a server that operates and manages users' SNS accounts. SNS can be, for example, Instagram, Facebook, Twitter, TikTok, Kakao Page, etc.
[0110] Server 2100 receives multiple 2D images of a user's face from user terminal 2010 or SNS server 2020. It extracts multiple 2D images related to the user's face from the received images, and generates a 3D mask image corresponding to the lower part of the user's face using 3D modeling based on the extracted images. The generated 3D mask image is then fitted onto the front of the mask. Here, the 3D mask image may include at least the lower part of the user's nose and mouth, corresponding to the mask's covering portion.
[0111] Figure 17 For detailed explanation Figure 16 The detailed block diagram of server 2100 shown is as follows: Figure 17 As shown, the server 2100 may include: a receiving unit 2110 that receives multiple 2D images of a user's face; an image generation unit 2120 that extracts multiple 2D images related to the user's face from the received multiple 2D images and generates a 3D mask image corresponding to the lower part of the user's face through 3D modeling based on the extracted multiple 2D images; and an image matching unit 2130 that matches the generated 3D mask image to the front of the mask.
[0112] The printer can perform the function of printing the 3D mask image matched by the server 2100 onto the front of the mask to form the face display part of the mask.
[0113] Figure 18 For illustrative purposes Figure 16 The flowchart shown illustrates the operation process of the mask manufacturing system, and describes a mask manufacturing method according to another preferred embodiment of the present invention.
[0114] Please see Figures 16 to 18 The server 2100 can receive multiple 2D images of the user's face from at least one of the user terminal 2010 and the SNS server 2020 (step S21).
[0115] For example, server 2100 can receive a 2D image of a user's face captured by user terminal 2010. For example, server 2100 can receive 2D images of the user's face captured or captured and stored in user terminal 2010 from user terminal 2010.
[0116] To this end, server 2100 may invite user terminal 2010 to capture a 2D image of the user's face. When inviting the 2D image, server 2100 indicates to the user interface whether to activate the user terminal 2010's camera for live capture or select a photo pre-saved in the user terminal 2010, and activate the camera for live capture or display a preview list of photos pre-saved in the user terminal 2010 according to the user's selection.
[0117] For example, server 2100 can also receive 2D images of a user's face from SNS server 2020, which manages the user's SNS account. For instance, server 2100 can receive access information from user terminal 2010 for the SNS server 2020 corresponding to the user's account, thereby allowing the SNS server 2020 corresponding to the user's account to collect multiple 2D images including the user's face. That is, server 2100 collects photos posted by the user on Instagram, Facebook, Twitter, KakaoStory, etc.
[0118] Next, the server 2100 can extract multiple 2D images related to the user's face from the received multiple 2D images (step S22). The multiple 2D images may include a frontal image of the user, a left side image, and a right side image, etc.
[0119] Server 2100 can generate a 3D mask image corresponding to the lower part of the user's face based on the extracted multiple 2D images through 3D modeling (step S23). Here, the 3D mask image includes at least the lower part of the user's nose and mouth, corresponding to the cover part of the mask.
[0120] Figure 19 For detailed explanation Figure 18 The flowchart shown illustrates the process of generating a 3D mask image. Figure 19 The action can be performed by the image generation unit 2120 of the server 2100.
[0121] like Figure 18 As shown, firstly, server 2100 can extract multiple feature points corresponding to the user's face from the received multiple 2D images (step S31). For example, server 2100 can extract multiple feature points corresponding to the user's face by analyzing the user's frontal image, left side image, right side image, etc.
[0122] Next, the server 2100 can transform the reference 3D face model into a 3D face model corresponding to the user's face based on the extracted feature points (step S32). Therefore, the server 2100 can generate a 3D face model corresponding to the user's face.
[0123] Then, server 2100 can generate a 3D mask image corresponding to the lower face shape of the user's face from the 3D face model corresponding to the transformed face (step S33). The 3D mask image can be a 3D image representing the user's lower face, corresponding to the mask cover in the user's 3D face model. For example, the 3D mask image can correspond to at least the parts related to the user's breathing, such as the lower part of the nose including the nostrils and the lower face portion of the mouth.
[0124] Please refer to it again. Figure 18 The server 2100 can match the generated 3D mask image to the front of the mask (step S24). The printer can form the face display part of the mask by printing the matched 3D mask image to the front of the mask (step S25).
[0125] Figure 20 This is a diagram illustrating a face mask with a face display area formed on the front using a printer.
[0126] like Figure 20 As shown, a face display section 3100 is formed on the front of the mask 3000, which is printed with a 3D mask image corresponding to the shape of the user's lower face, including the user's nose and mouth. The mask is breathable and can block at least one of droplets, sand, smoke, toxic gases, smog, and viruses from entering the human body.
[0127] The above embodiments are merely illustrative of the present invention and not intended to limit it. Those skilled in the art should understand that modifications, variations, or equivalent substitutions can be made to the present invention without departing from its spirit and scope, and all such modifications and substitutions should be covered within the scope of the claims. Therefore, any future changes to the embodiments of the present invention should not exceed the technical scope of the present invention.
