The displayed guide image is an image for guiding the hair cutter to the hair cutting line. Further, the image is displayed superimposed on the head of the person whose hair is being cut.
The cut line guided by the guide image is a line indicating the length of hair to be left (in other words, the length of hair to be cut) and the angle at which the hair is to be cut. This cut line is determined according to the hairstyle selected by the person whose hair is being cut and the shape of the person's head. Moreover, this cut line includes not only the cut line for the base process but also the cut line for the thinning cut.

The section identification module 318 inputs the photographed image taken by the camera unit 360 into the section estimation model, and identifies the section corresponding to the hair being held by the person cutting the hair. The section estimation model into which the photographed image is input is generated by having a machine learning model such as a neural network learn a large amount of teacher data. The teacher data referred to here is data consisting of a photographed image of a person holding hair and an ID of a section where the hair to be held grows. The generated section estimation model inputs the photographed image taken by the camera unit 360 and outputs the section ID.
For the section specified by the section specifying module 318, a guide image is displayed by the guide display module 317.

The uncut identifying module 319 refers to the process management table 700 and identifies sections where the hair has not been cut by the hair cutter. For the identified section, a guide image is displayed by the guide display module 317 in order to prompt the hair cutter to cut the hair.

1-2. Operation The presetting sequence 800, first process control flow 900, guide display flow 1000, and second process control flow 1100 will be described below as operations of the haircut support system 100.

1-2-1. Preset sequence 800
FIG. 8 shows an example of a preconfiguration sequence 800. A presetting sequence 800 shown in the figure is a sequence executed in order for the smart glasses 300 to acquire various data necessary for a haircut from the data management server 200. This sequence is executed while the user (specifically, the person cutting hair) is wearing the smart glasses 300.

First, the information acquisition module 311 of the smart glasses 300 requests a hairstyle selection screen from the data management server 200 (step 801). In response to this request, the information providing module 211 of the data management server 200 transmits the hairstyle selection screen data 221 to the smart glasses 300 (step 802). The information acquisition module 311 of the smart glasses 300 that has received this data displays a hairstyle selection screen based on the data (step 803). On the displayed screen, the user selects an image of the hairstyle desired by the person whose hair is being cut by voice operation.

When any hairstyle image is selected on the screen, the information acquisition module 311 transmits the hairstyle ID corresponding to the selected image to the data management server 200 (step 804). The information providing module 211 of the data management server 200 that received this ID then transmits the head shape selection screen data 222 to the smart glasses 300 (step 805). The information acquisition module 311 of the smart glasses 300 that has received this data displays a head shape selection screen based on the data (step 806). On the displayed screen, the user selects an image of the shape of the head of the person whose hair is to be cut by voice operation.

When any head shape image is selected on the screen, the information acquisition module 311 transmits the head shape ID corresponding to the selected image to the data management server 200 (step 807). The information providing module 211 of the data management server 200 that has received this ID refers to the scalp model table 500 and specifies the scalp model ID corresponding to the ID. The module then acquires the scalp model data 223 identified by the specified ID from the auxiliary storage device 220 (step 808).

The module also refers to the cut recipe table 600 and identifies the cut recipe ID corresponding to the acquired pair of hairstyle ID and scalp model ID. The module then acquires the cut recipe data 400 identified by the specified ID from the auxiliary storage device 220 (step 809).

The module also refers to the acquired cut recipe data 400 and acquires the explanatory video data 224 identified by the explanatory video ID of the data from the auxiliary storage device 220 (step 810).
The data module transmits the acquired scalp model data 223, cut recipe data 400, and explanatory video data 224 to the smart glasses 300 (step 811).

The information acquisition module 311 of the smart glasses 300 that has received the data stores the received scalp model data 223 and explanatory video data 224 in the auxiliary storage device 320 (step 812). The module also stores the received cut recipe data 400 in the process management table 700 (step 813).
The above is a description of the presetting sequence 800.

According to the preset sequence 800 described above, the user can obtain the cut recipe data 400 and explanatory video data 224 for achieving a desired hairstyle. In addition, the user can obtain scalp model data 223 that matches the head shape of the person whose hair is being cut.

1-2-2. First process control flow 900
FIG. 9 shows an example of a first process control flow 900. A first process control flow 900 shown in the figure is a processing flow executed by the smart glasses 300 to support haircuts after the preset sequence 800 is executed. This sequence is executed while the user (specifically, the person cutting hair) is wearing the smart glasses 300.

First, the process management module 313 of the smart glasses 300 sets, among the area IDs registered in the process management table 700, the area IDs associated with the cut completion flag "false" as processing targets (step 901). . The section ID set as a processing target here becomes a target of a guide display flow 1000 described later.

Next, the module refers to the process management table 700 and identifies the explanatory video ID corresponding to the section ID to be processed. Then, the module acquires the commentary video data 224 identified by the specified commentary video ID from the auxiliary storage device 320 (step 902). The module then displays an explanatory video based on the acquired data (step 903) (see FIG. 13). By watching this explanatory video, the user can learn specifically how to cut hair corresponding to the section.

Next, the module determines whether the haircut for the section is completed (step 904). More specifically, the module determines whether a voice operation notifying completion of the haircut in the section has been received. As a result of this determination, if the haircut in the section has not been completed (No in step 904), the module waits. On the other hand, if the result of this determination is that the haircut for the section has been completed (Yes in step 904), the module updates the process management table 700 (step 905). Specifically, the module changes the cut completion flag associated with the processing target section ID in the process management table 700 from "false" to "true".

Next, the module refers to the process management table 700 and determines whether all the partition IDs have been processed (step 906). Specifically, the module determines whether all section IDs are associated with the cut completion flag "true" in the process management table 700. As a result of this determination, if all the partition IDs are not subject to processing (No in step 906), the module returns to step 901. As a result of this determination, if all partition IDs are to be processed (Yes in step 906), the module ends this processing flow.
The above is a description of the first process control flow 900.

According to the first process management flow 900 described above, the section IDs registered in the process management table 700 are sequentially targeted for the guide display flow 1000.

1-2-3. Guide display flow 1000
FIG. 10 shows an example of a guide display flow 1000. A guide display flow 1000 shown in the figure is a processing flow that is repeatedly executed by the smart glasses 300 when a section ID is set as a processing target. This sequence is executed while the user (specifically, the person cutting hair) is wearing the smart glasses 300.

First, the head detection module 315 of the smart glasses 300 acquires a captured image captured by the camera unit 360 (step 1001). Then, the module analyzes the acquired captured image and three-dimensionally detects the inclination and size of the head of the person whose hair is being cut (step 1002).

Next, the scalp model display module 316 of the smart glasses 300 generates a scalp model image to be displayed over the head, based on the detected inclination and size of the head (step 1003). Specifically, this module acquires the scalp model data 223 stored in the auxiliary storage device 320. The module then generates a translucent image representing a scalp model viewed from the same perspective as the head and resized to overlap the head.

After generating this image, the module displays the image superimposed on the head (step 1004). As a result, the user can see the scalp model superimposed on the head. This scalp model has scalp compartments. Therefore, the user can easily grasp the range of hair strands that should be held in one haircut.

Next, the guide display module 317 of the smart glasses 300 refers to the process management table 700 and identifies the length and angle of the hair corresponding to the section ID to be processed (step 1005). The module then generates a guide image based on the specified hair length and angle and the detected head inclination and size (step 1006). The generated guide image will be described later. The module then displays the generated guide image (step 1007).
The above is the explanation of the guide display flow 1000.

FIG. 13 shows an example of a screen displayed on the smart glasses 300 as a result of the guide display flow 1000 described above. However, in the screen shown in the figure, the scalp model image is omitted to avoid complicating the drawing.

The screen shown in FIG. 13 has a guide image 1301. This guide image 1301 is a translucent image of a substantially rectangular plate. The plate indicated by this guide image 1301 extends at a predetermined angle from the section identified by the section ID to be processed, and its tip indicates a hair cut line. The cutting line indicated by the tip of this plate indicates the length of hair to be left (in other words, the length of hair to be cut) and the angle at which the hair should be cut. The hair length indicated by this cut line is determined based on the hair length specified above. More specifically, the hair length is determined based on the value obtained by multiplying the specified hair length (ratio) by a reference length specified in advance by the user, for example. . Further, the angle at which the hair is cut indicated by the cut line is determined based on the specified angle.

The user cuts hair with reference to this guide image 1301. Specifically, the user first identifies a section of the guide image 1301 that is the starting point of the plate, and grasps a strand of hair extending from that section. Next, the user stacks the gripped hair bundles along the plate. Then, the user cuts the hair bundle along the cut line of the guide image 1301 in this state. As a result, the user can cut the hair growing from the section to be treated according to the specified length and angle.

The screen shown in FIG. 13 also has an explanatory video 1303. By viewing this explanatory video 1303, the user can learn specifically how to cut hair corresponding to the section to be processed.

1-2-4. Second process control flow 1100
FIG. 11 shows an example of a second process control flow 1100. The second process management flow 1100 shown in the figure is different from the first process management flow 900 described above, and realizes a user-initiated haircut. More specifically, in the first process control flow 900 described above, the order of haircuts is determined in advance, whereas in this second process control flow 1100, the order of haircuts is determined by the user. Can be done.
This second process management flow 1100 and the first process management flow 900 described above are selectively executed by the user.

In this second process control flow 1100, first, the section identification module 318 of the smart glasses 300 acquires a captured image captured by the camera unit 360 (step 1101). Then, the module inputs the acquired captured image into the section estimation model and identifies the ID of the section corresponding to the hair held by the user (step 1102).

Once the section ID is specified, the process management module 313 of the smart glasses 300 sets the specified section ID as a processing target (step 1103). The section ID set as the processing target here becomes the target of the guide display flow 1000 described above.

Next, the module refers to the process management table 700 and identifies the explanatory video ID corresponding to the section ID to be processed. Then, the module acquires the commentary video data 224 identified by the specified commentary video ID from the auxiliary storage device 320 (step 1104). Then, the module displays an explanatory video based on the acquired data (step 1105) (see FIG. 13). By watching this explanatory video, the user can learn specifically how to cut hair corresponding to the section.

Next, the module determines whether the haircut for the section is completed (step 1106). More specifically, the module determines whether a voice operation notifying completion of the haircut in the section has been received. As a result of this determination, if the haircut in the section has not been completed (No in step 1106), the module waits. On the other hand, if the result of this determination is that the haircut in the section has been completed (Yes in step 1106), the module updates the process management table 700 (step 1107). Specifically, the module changes the cut completion flag associated with the processing target section ID in the process management table 700 from "false" to "true".

Next, the module determines whether the user has completed all haircut work (step 1108). More specifically, the module determines whether a voice operation notifying that all haircut work is completed has been received. As a result of this determination, if it is determined that the user has not completed all haircut work (No in step 1108), the module returns to step 1101. On the other hand, as a result of this determination, if it is determined that the user has completed all haircut work (Yes in step 1108), the uncut identifying module 319 determines whether there is any uncut hair (step 1109). ).

Specifically, the module refers to the process management table 700 and determines whether all section IDs are associated with the cut completion flag "true". As a result of this determination, if there is any uncut hair (Yes in step 1109), the module sets a section ID that is not associated with the cut completion flag "true" to be processed (step 1110). The section ID set as the processing target here becomes the target of the guide display flow 1000 described above. Therefore, a guide image is displayed to prompt the user to cut the hair in the section where the hair is left uncut.

On the other hand, if the result of the above determination is that there is no uncut hair (No in step 1109), the module ends this processing flow.
The above is the description of the second process control flow 1100.

According to the second process control flow 1100 described above, the user can determine the order of haircuts. In addition, it is possible to prevent hair from being left uncut.

2. Modifications The above embodiment may be modified as follows. Note that the following modifications may be employed in combination.
(1) As described above, the haircut support system 100 is intended to support haircuts by general users who are not hairdressers or barbers. However, users of this system are not necessarily limited to general users, and may be used by beauticians and barbers as a system to support their work.

(2) In the above embodiment, smart glasses are used as the user terminals. However, the smart glasses are just one example of a user terminal, and other head-mounted computers (for example, head-mounted displays) may be used instead of the smart glasses.

(3) In the above embodiment, smart glasses are used as the user terminals. Therefore, the scalp model image and guide image are displayed in front of the user's eyes. However, this display method is just an example, and another display method may be adopted. For example, a stationary display may be placed near the user, and the scalp model image and guide image may be displayed on this display. In that case, the user terminal does not necessarily have to be a head-mounted type, and may be a stationary or portable computer. This stationary or portable computer wirelessly receives captured images from a camera attached to the user's head, and displays the captured images with scalp model images and guide images superimposed on a stationary display. good.

(4) In the above embodiment, an image of a substantially rectangular plate is displayed as the guide image (see FIG. 13). However, this image is just an example, and any other image may be used as long as the cut line and the corresponding section can be identified.

(5) In the above embodiment, the cutting angle is also represented in the guide image in addition to the hair length. However, the display of the cutting angle is not necessarily essential, and may be omitted.

(6) In the above presetting sequence 800, the user is asked to select the shape of the head of the person whose hair is being cut. However, instead of this, the user may be allowed to upload measurement data of the head shape of the person whose hair is being cut. The measurement data uploaded here is, for example, head shape data measured by the person having their hair cut using a special device.

The data management server 200 that has received this measurement data may select a scalp model that is close to the shape of the head of the person whose hair is being cut, based on the received measurement data. Alternatively, the data management server 200 may generate a custom-made scalp model based on the measurement data.

(7) In the above embodiment, the hair length in the cut recipe data 400 is expressed as a ratio. However, this ratio is just one example of a parameter representing hair length. Instead of a relative value such as this ratio, the hair length may be represented by an absolute value.

(8) In the above embodiment, the angle of the cut line is determined based on the angle of the cut recipe data 400. However, instead of this, the angle of the cut line may be determined based on the hair length in the cut recipe data 400.

For example, assume that one section is identified by the section identification module 318 in the second process control flow 1100 described above. In that case, the guide display module 317 may calculate the angle of the cut line based on the identified section and the lengths of hairs associated with sections adjacent to the specified section. With this method as well, the cut lines between adjacent sections can be made linear instead of step-like.

As another example, suppose that two or more divisions are identified by the division identification module 318 in the second process control flow 1100 described above. In that case, the guide display module 317 may calculate the angle of the cut line based on the lengths of the plurality of hairs associated with the two or more identified sections. In this case as well, the cut lines between adjacent sections can be straight rather than stepped.

(9) In the above embodiment, the smart glasses 300 accept voice operations. However, the voice operation is just one example of the operation method, and other operations (for example, line-of-sight operation or touch operation) may be accepted.

(10) The smart glasses 300 may determine whether to display a guide image for a thinning cut depending on the amount of hair on the head of the person whose hair is being cut. More specifically, the smart glasses 300 may display a guide image for a thinning cut when the amount of hair of the person whose hair is being cut satisfies a predetermined condition.

Here, specifically, the case where the amount of hair on the head satisfies the predetermined condition is the case where the amount of hair on the head is large. More specifically, this case is a case where a variable indicating the amount of hair, which is preset in the smart glasses 300, indicates that there is a large amount of hair. A user with a large amount of hair sets the variable in advance to a value indicating that the user has a large amount of hair.

The smart glasses 300 refer to the variable and display a guide image for thinning cut if the value of the variable indicates a large amount of hair. On the other hand, if the value of the variable does not indicate a large amount of hair, the smart glasses 300 omit displaying the guide image for thinning cut.

(11) A hairdresser or barber may create the cut recipe data 400 by themselves and upload it to the data management server 200. The uploaded cut recipe data 400 is stored in the auxiliary storage device 320 of the data management server 200, and can be freely downloaded by the user.
The data management server 200 may manage the number of downloads for each cut recipe data 400, and the administrator of the server may pay royalties to the creator of the cut recipe data 400 according to the number of downloads.

(12) In the above embodiment, the scalp model data 223 is prepared for each head shape. Alternatively, scalp model data 223 may be prepared for each combination of head shape and hairstyle.

In that case, in the scalp model table 500, a combination of a head shape ID and a hairstyle ID will be associated with a scalp model ID. When using this table, the data management server 200 specifies the scalp model ID corresponding to the combination of head shape ID and hairstyle ID selected by the user. The server then transmits the scalp model data 223 identified by the specified ID to the smart glasses 300.

The smart glasses 300 display a scalp model image on a transparent display based on the scalp model data 223. The shape of each section shown in the scalp model image is determined according to the head shape and hairstyle of the person whose hair is being cut.

(13) Haircut support system 100 may be made compatible with multiple languages. Specifically, the user may be able to select the language in which the smart glasses 300 can be operated by voice. Further, the explanatory video data 224 stored in the data management server 200 may be prepared for each language, and the server may transmit the explanatory video data 224 corresponding to the language used by the user to the smart glasses 300.

(14) In the above embodiment, the cut recipe data 400 is prepared for each combination of hairstyle and scalp model. Alternatively, the cut recipe data 400 may be prepared for each combination of hairstyle, head shape, and forehead shape.

In that case, in the cut recipe table 600, a combination of a hairstyle ID, a scalp model ID, and a forehead shape ID will be associated with the cut recipe ID. When using this table, the data management server 200 specifies a cut recipe ID corresponding to the hairstyle ID and forehead shape ID selected by the user, and the scalp model ID specified by its own server. The server then transmits the cut recipe data 400 identified by the specified ID to the smart glasses 300.

The smart glasses 300 display a guide image on a transparent display based on the cut recipe data 400. The cut line indicated by the displayed guide image is determined according to the hairstyle, scalp model, and forehead shape.

Note that in the above example, the data management server 200 prepares the cut recipe data 400 for each forehead shape in advance. However, instead of this, the server may modify the cut recipe data 400 corresponding to the hairstyle and head shape according to the user's forehead shape, particularly for the section corresponding to the forehead.
