1 is a schematic diagram of a system 10 for measuring a body size and recommending a clothing size using an image according to an embodiment of the present invention.

Referring to FIG. 1 , a system 10 for measuring a body size using an image and recommending a clothing size will be schematically described.

An embodiment of the present invention is operated based on the server 100 and is affiliated with a custom clothing manufacturer and an online shopping mall.

The server 100 provides a service application to obtain an image for measuring the user's body size. Then, the user joins the server 100 and installs the service application in the terminal 300, then takes a body image of the user and provides it to the server 100, and the server 100 uses the body size measurement model The user's body size is measured.

The user's body size measured in this way is provided to a custom clothing manufacturer and used to manufacture the user's custom clothing.

In addition, the server 100 provides the body size measurement model to the affiliated online shopping mall, and when the user purchases specific clothing, compares the corresponding clothing with the user's measured body size and recommends a size suitable for the user.

As described above, the system 10 for measuring body size and recommending clothing size using an image according to an embodiment of the present invention measures and manages the user's body size using only the user's image, and manufactures affiliated customized clothing The company will provide the user's body size to the online shopping mall.

Hereinafter, with reference to other drawings, an embodiment of the present invention will be described in more detail.

2 and 3 are flowcharts of a method of measuring a body size using an image and recommending a clothing size according to an embodiment of the present invention.

A method of measuring a body size and recommending a clothing size using an image according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3 .

First, the measurement unit 110 measures the body size of the user from the user image taken from the user terminal 300 using the body size measurement model. (Step S100)

Step S100 will be dealt with in more detail below, but will be briefly described.

In an embodiment of the present invention, the user terminal 300 refers to a terminal 300 having a 2D camera in a device, such as a general mobile phone, smart phone, or tablet PC.

In recent years, shopping for clothing in online stores has become just as common as buying clothing offline.

To that extent, it was decided that any user (consumer) who wants to purchase clothes should be able to measure their body size without restrictions, and it is recently that most people have smartphones (mobile phones) that can implement this. it was

In addition, most smartphones of the present age do not have a professional function such as a 3D camera, but have a 2D image shooting function, so in an embodiment of the present invention, the user's body size is measured based on the 2D image. .

In addition, the measurement unit 110 of the server 100 stores the body size of the user measured in step S100 in the database 170 .

After step S100, the information providing unit 140 provides the measured body size of the user to the customized clothing manufacturer for the production of the customized clothing ordered by the user. (Step S200)

This means that the user places an order for customized clothing with a customized clothing manufacturer in order to produce customized clothing, and the information providing unit 140 of the server 100 provides information about the user's body size to the customized clothing manufacturer. .

For this reason, the user can visit the custom clothing manufacturer directly to measure the body size once more accurately, but it is also possible to use the body size received from the information providing unit 140 of the server 100 .

In addition, the customized clothing manufacturer manufactures the ordered customized clothing using the user's body size received from the information providing unit 140 of the server 100 .

After step S200, the server 100 receives information on the fitting or temporary sewing of the user's ordered custom clothing from the customized clothing manufacturer. (Step S300)

Fitting of customized clothing means that the production of customized clothing is completed and the user puts on the completed customized clothing, and temporary fitting of customized clothing means checking in the middle whether the customized clothing is being produced properly.

Since Gabon may vary depending on the circumstances of the customized clothing manufacturer, the server 100 receives the fitting result or the Gabon result.

At this time, the information the server 100 receives from the custom clothing manufacturer is, for example, whether the customized clothing manufactured based on the body size, such as the left arm length 2 mm short, shoulder length 2 mm ? If it does not match, it may be information including how much it does not match, and the like.

After step S300, the learning module 150 of the server 100 learns the body size learning module 150 using the information received in step S200. (Step S400)

In this way, the server 100 measures the user's exact body size from the user's image by using the body size measurement model, and provides this to a customized clothing manufacturer to assist in the production of customized clothing.

And, every time customized clothing is manufactured, information on the fitting or temporary fitting of the customized clothing is received, and the body size measurement model is learned using the received information, so that the accuracy of measuring the body size gradually improves.

According to an embodiment of the present invention, the server 100 may provide the body size measurement model to the online shopping mall affiliated with the server 100 .

More specifically, the server 100 provides a size recommendation function to an affiliated online shopping mall using a body size measurement model. (Step S500)

Accordingly, when a member (user) who uses an online shopping mall uses the web or app to view an online shopping mall and purchases a specific product, and selects a size recommendation function, the size recommendation module of the server 100 is ) and the actual size of the product to recommend a suitable size for the user.

The step of providing the size recommendation function (step S500) will be described in more detail with reference to FIG. 3 .

The measuring unit 110 of the server 100 measures the body size of the member from the user image obtained from the mobile device of the member of the online shopping mall using the body size measurement model. (Step S510)

Step S510 is the same as step S100 except that the member is an online shopping mall member.

In step S510 , when the member of the online shopping mall is a subscriber of the service provided by the server 100 , the user information is checked and the body size of the user stored in the database 170 is loaded. (Step S515)

Therefore, if a member of the online shopping mall is already a subscriber of the service provided by the server 100 and has a history of measuring body size, it means that the user's body size stored in the database 170 is loaded and used in the online shopping mall.

Accordingly, step S510 may be replaced with step S515 depending on whether the online shopping mall member has subscribed to the server 100 .

After step S510 or S515, when the size recommendation module of the server 100 selects the size recommendation function from the member on the page of a specific product in the online shopping mall, the actual size of the specific product and the body size of the member (user) are matched. . (Step S530)

For example, when the clothing selected by the member (user) is a top, sizes such as neck circumference, chest width, waist circumference, arm length, and total length may be matched.

After step S530, the size recommendation module of the server 100 recommends the size of a specific product to the member as a result of the matching. (Step S550)

According to an embodiment of the present invention, since a body size accurately measured using a body size measurement model is matched with an actual size of clothing to recommend a size, the user can trust and purchase the corresponding size.

In an embodiment, the server 100 may re-learn the body size measurement model using a review (feedback) of a member (user) purchasing clothes using a size recommendation function in an online shopping mall.

In more detail, the server 100 receives information about a fitting result of the specific product from the member who ordered the specific product. (Step S570)

Then, the learning module 150 of the server 100 learns the body size measurement model by using the information on the fitting result of a specific product. (Step S590)

For this reason, the server 100 can learn the body size measurement model using an actual product purchase case to further improve its accuracy.

In one embodiment, the server 100 recommends the size of the specific product to the member in consideration of the fitting style of the specific product input from the member in the size recommendation step (step S550).

In this case, the fitting style refers to a fitting style such as whether to wear a perfect fit, such as a skinny, regular size, semi-overfit, or overfit, to wear a regular size, to wear a slightly large size, or to wear a large size.

Accordingly, the size recommendation module recommends the size of the clothing by matching the measured body size of the user (member) with the actual size of the specific clothing, and recommends the size down or up in consideration of the fitting style selected by the user.

Through this, when the user wants to purchase clothes with a fitting style other than the normal size, he or she can select a fitting style and receive a size recommendation.

In one embodiment, the size recommendation module of the server 100 may refer to size review information input by the member for one or more products previously purchased in the online shopping mall for size recommendation.

Therefore, the size recommendation module of the server 100 compares the actual size of the clothing that the member has previously purchased with the actual size of the member, and refers to how the member evaluated the size of the corresponding clothing, Accuracy can be improved by referring to size recommendations.

4 is a flowchart illustrating in more detail the step of measuring the user's body size in FIG. 2 , and FIG. 5 is a diagram illustrating the guiding line 200 displayed on the shooting screen of the user terminal 300 in the image acquisition process. , FIG. 6 is a diagram illustrating that the user proceeds to photograph the body using the terminal 300, and FIG. 7 illustrates the user's 3D standard body model selected by the image analysis module 130 using the user's photographed image It is a diagram, and FIG. 8 is a diagram illustrating a result of measuring each size of a user's body part using a user's photographed image.

The step of measuring the user's body size (step S100 ) will be described in more detail with reference to FIGS. 4 to 8 .

The server 100 acquires the front and side images of the user photographed through the photographing means of the user terminal 300 . (Step S110)

In this case, the image is taken while the user's body in the shooting screen of the terminal 300 is positioned within the range of the guiding line 200 displayed on the shooting screen of the user terminal 300 .

In one embodiment, the guiding line 200 is located at a specific distance from the user's horse to induce the user to take a specific posture, and has the shape of the front or side of the person's body, and the front guiding line 200 is the user's It is a shape that induces the arms to open at a predetermined angle to the torso, and the user's legs to open at a predetermined angle, and the server 100 considers the user's body information, It is characterized by adjusting the size.

More specifically, first, the guide providing module 115 of the server 100 displays the guiding line 200 on the shooting screen of the user terminal 300 .

Then, the image acquisition module 120 of the server 100 acquires the front and side images of the user photographed through the photographing means of the user terminal 300 .

Referring to FIG. 5 , the front and side images of the user acquired by the image acquisition module 120 of the server 100 are located within the range of the guiding line 200 of the user's body being photographed within the shooting screen of the terminal 300 . It was filmed in

At this time, the guiding line 200 is displayed as a shooting screen of the terminal 300 , and it is located at a specific distance from the terminal 300 to the user so that the user's body is included in the guiding line 200 . to induce it to do so. (When the guiding line 200 is displayed on the shooting screen of the terminal 300 , it means that the display is overlapped with the shooting screen of the terminal 300 .)

As mentioned above, the server 100 according to the embodiment of the present invention provides a service application stored in the medium to execute the method according to the embodiment of the present invention.

Accordingly, in the following embodiments of the present invention, things performed by the terminal 300 may mean being performed through a service application.

When the user executes the service application and activates the photographing function, the camera of the terminal 300 is activated and the photographing screen is turned on as shown in FIG. 6 . And, the service application displays the guiding line 200 on the shooting screen of the terminal 300 as programmed in advance.

At this time, in the embodiment of the present invention, when the guide line 200 is displayed as a shooting screen, the guide providing module 115 may be programmed in the service application provided by the server 100, and when the service application is driven. Each guide providing module 115 of the server 100 may control this.

The implementation of the guide providing module 115 as described above can be easily selected by the practitioner according to the situation.

When the user installs the service application to measure the body size and drives it, the guide providing module 115 displays the guiding line 200 on the shooting screen of the terminal 300 through the service application.

5 (A) is a view illustrating a front guiding line 200 for allowing a user to take a frontal picture of the body, (B) is a side guiding line 200 for taking a side picture It is a drawing.

The user checks the front guiding line 200 displayed on the shooting screen of the terminal 300 with his eyes, and adjusts his/her posture so that his/her body is located within the guiding line 200 as shown in FIG. 6 , and guiding The providing module detects that the user's body is accurately positioned within the guiding line 200 and takes an image of the user.

In addition, when it is determined that the user's front image is properly obtained, the guide providing module 115 displays the side guiding line 200 on the shooting screen of the terminal 300 to induce the user to change the ritual, and the user's body If it is determined that the side is located within the guiding line 200, the user's side image is acquired.

At this time, the method for the server 100 to obtain the user's image may be obtained by automatically capturing the user's posture as described above, but may also be photographed with a timer set, and another user may click the photographing button Various methods may be applied, such as being able to be photographed by the user, or remotely controlled by the user himself/herself.

In addition, the order in which the server 100 acquires the front image and the side image is not limited, and the number of images for acquiring the front image or the side image may also vary according to the implementation of the present invention.

For example, the image acquisition module 120 of the server 100 may acquire both the left side image and the right side image of the user, or may acquire only one side image.

The reason that the guiding line 200 has such a shape is that when the user's arm is attached to the body, it is difficult to separate the arm and the body on the image, and many errors occur in this process.

In addition, in this process, if the angle between the user's arm and the torso is set too large, it is difficult to separate the user's torso and the arm from the shoulder, this is because an error occurs again in this process.

Therefore, the server 100 according to the embodiment of the present invention does not simply display the guiding line 200 to allow the user to take a specific posture by being located at a specific distance from the terminal 300, but a front image later It is to provide and display the guiding line 200 by the algorithm calculated to accurately measure the user's body size using the lateral image.

In one embodiment, the server 100 may receive the height and weight of the user through the terminal 300 for this implementation, and the server 100 considers this and determines the shape and size of the guiding line 200 . can be adjusted

Accordingly, the server 100 adjusts the arm angle of the guiding line 200 in consideration of the user's body information input through the terminal 300 .

More specifically, the server 100 may set the width and thickness of the guiding line 200 to be wider as the value of the weight input from the user is higher, and may greatly adjust the angle of the arm and the torso.

For example, if a person weighing 100 kg stands with his arms spread apart from the torso in the same way as a person weighing 45 kg, the torso and arms may overlap due to the thickness of the torso and arms.

In addition, in the case of a user who weighs more than the average, an error may occur because the body exceeds the guiding line 200, so for a user with a weight exceeding the reference range, the guiding line 200 is corrected and displayed as a shooting screen. means that

While the present applicant proceeds with shooting with the guiding line 200 and conducting an experiment to measure the body size, most of the people with normal body conditions are accurately photographed and the body size is also accurately measured, but the standard In the case of a person without physical condition, it was found that it was somewhat difficult to position the body within the guideline, and the above solution was obtained as a way to solve this.

Through the above description, the server 100 has acquired an image for measuring the user's body size.

After step S110, the edge extraction unit 125 of the server 100 recognizes an area corresponding to the user's body from the front and side images of the user, and extracts the recognized area by separating it from the background. (Step S130)

In more detail, although the user's front and side images are acquired using the guiding line 200, the image includes a background other than the user's body, so the edge extraction unit 125 for measuring the user's body size ) means to extract the edge part corresponding to the user's body region from the background.

At this time, since the edge extraction unit 125 recognizes that the user's body is located within the guiding line 200 in the image, the accuracy is greatly improved compared to extracting the user's body edge from a general image. have.

In one embodiment, step S130 may further include the step of the edge extraction unit 125 determining the image of the clothes worn by the user as noise in the body region of the user recognized in step S130 and removing the image.

The ideal shooting method is for the user to take front and side images wearing clothes that clearly show the outline of the body, but if the photo is taken wearing clothes that do not, the process of judging the image of the clothes as noise and removing them as above is performed it might be

Step S130 Next, the image analysis module 130 analyzes the edge extracted in step S130 and selects a 3D standard body model corresponding thereto. (Step S150)

At this time, the image analysis module 130 receives front and side images and 3D images of the body of the model with different body conditions, and learns how to generate a 3D standard body model using the front and side images of the body. has been

More specifically, the image analysis module 130 generates a 3D standard body model when the front and side images of a specific user are input by inputting the front and side images of the model wearing clothes that clearly reveal the appearance of the body together with the 3D image. The method is learned, and the accuracy is secured as this learning is performed multiple times (hundreds, thousands or more) through images of models with different body conditions.

Through this process, the image analysis module 130 selects the 3D standard body model of the user as shown in FIG. 7 .

In one embodiment, when the server 100 fails to recognize a region corresponding to the user's body in the image or the extracted edge does not correspond to a normal body shape, the server 100 provides the user with posture correction and then re-photographing or re-photographing after conversion. you can request

More specifically, if the user's body area recognition fails or the extracted edge does not correspond to a normal human body shape as above, the user's shooting posture is incorrect or the user is wearing clothes that are difficult for the computer to recognize. It means making a judgment and requesting the user to take a picture again after correcting the posture, or to take a picture again after changing to a different outfit.

After step S150, the image analysis module 130 corrects the 3D standard body model selected in step S230 in consideration of at least one of the user's body information analysis result or the extracted edge analysis result. (Step S170)

More specifically, correcting the 3D standard body model selected by the image analysis module 130 in step S150 into a 3D model optimized for the user in consideration of at least one of the user's body information analysis result or the extracted edge analysis result it means.

Accordingly, the 3D standard body model corrected in step S170 may be a more accurate model than the 3D standard body model selected in step S150.

An object of the present invention is to measure the body size by using the 2D camera of the terminal 300 without using a professional photographing apparatus such as a 3D photographing apparatus.

At this time, since the image analysis module 130 is trained through numerous models, it generates a sufficiently accurate 3D standard body model with only the extracted edge, but other conditions other than the edge information extracted from the 2D image are not involved. Therefore, it was necessary to improve the accuracy a little more.

Therefore, through various tests, it is possible to further improve the accuracy by using the analysis results of the user's body information (eg height, weight, physical condition, body specifics, etc.) and the analysis results of Edge. became

As described above, in the present invention, more accurate results can be obtained by correcting the selected 3D standard body model using the user's body information analysis result and edge analysis result.

After step S170, the calculator 135 obtains the user's body size using the 3D standard body model or the corrected 3D standard body model. (Step S190)

Since the 3D standard body model was obtained from the 2D image of the user through the above-described steps, the calculator 135 was able to obtain the sizes of all body parts of the user by using the 3D standard body model.

8 exemplifies obtaining the body size of various body parts of the user using the 3D standard body model or the corrected 3D standard body model.

Conventionally, in the case of tops, only fragmentary actual size information such as chest measurement, total length, arm length, and in the case of bottoms, total length, hem width, waist circumference, and thigh circumference was provided.

In this method, an error occurred in many cases because the user had to measure the user's body size himself, and this resulted in failure to select the size in many cases.

However, when the present invention described above is used, accurate data on the user's body can be obtained by forming an accurate 3D standard body model for the user, thereby enabling accurate size selection.

In addition to this, it is possible to calculate the exact size of all body parts of the user using the 3D standard body model, and furthermore, it is possible to actually fit the clothes virtually.

In one embodiment, the server 100 requests the user accessing the server 100 to input whether or not the weight has changed at regular intervals, and when there is a change in the user's weight by more than a threshold ratio, requesting the user to re-photograph the body. It is characterized in that the user's body size is re-acquired by using the first method or the second method of re-correcting the corrected 3D standard body model in consideration of the user's weight change.

For example, in a state in which the critical ratio is set to 10% in the server 100 and a corrected 3D standard body model is obtained in a state where the user's weight is 60 kg, the weight received from the user 5 months after that is If it was 68kg, it would exceed the critical ratio of 10%.

Accordingly, the server 100 responds to the user's weight change by re-acquiring the user's body size using the above-described first method or the second method. effect to be obtained.
