DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the information processing device, the information processing method, and the information processing program according to the present application will be described in detail with reference to the drawings. Note that the information processing device, the information processing method, and the information processing program according to the present application are not limited to the embodiments. In addition, the same parts in the following embodiments are given the same reference numerals, and duplicated explanations are omitted.

[0010] (Embodiment) A service using a three-dimensional model of a user is conceivable for custom-made clothing, etc. For example, a three-dimensional model of a user can be created using clothing for custom-made clothing, etc. For example, such clothing for measuring body size has elasticity and has predetermined marks or patterns arranged at predetermined positions, and a method for generating a three-dimensional model of a user by analyzing images taken from multiple directions of a user wearing such clothing for measuring body size is conceivable. In addition, in the method using clothing for measuring body size as described above, it may not be possible to obtain measurement values ​​of parts not covered by the clothing for measuring body size, such as the head and fingertips. For this reason, a method for obtaining measurement values ​​of each part by a technique for estimating body size from direct input of data or video data (e.g., images, videos, etc.) is also conceivable. Hereinafter, clothing for measuring body size according to the embodiment may cover each part of the body, such as the head and fingertips. In addition, the body size measurement method according to the embodiment may be a method for obtaining measurement values ​​of each part by a technique for estimating body size from direct input of data or video data. In addition, the body size measurement method of the embodiment may be a method using a measurement technology capable of measuring foot size by photographing the circumference of the foot (e.g., ZOZOMAT), a measurement technology capable of measuring finger size by photographing the circumference of the hand (e.g., ZOZOMAT for Hands), or a measurement technology capable of measuring chest size by photographing the circumference of the chest (e.g., ZOZOBRA).

[0011] Here, when generating a 3D model from a captured image of a user wearing such body size measurement clothing, in order to accurately match the positional relationship of each part of the 3D model with the user, it is necessary to measure the positional relationship (e.g., in which direction and how much it is shifted) for all points on the user's body. However, it is not practical to measure the positional relationship of all points on the user's body in this way.

[0012] Therefore, a method is conceivable in which the positional relationship of predetermined marks, i.e., the positional relationship of only a finite number of points, among the marks attached to the clothing for measuring body size, is measured, and a 3D model is generated based on the measurement results. When a 3D model is generated using such a method, the shape of the entire 3D model is estimated based on the shape of a general human being, so that there is an error between the positions of points other than the points where the positional relationship was actually measured and the actual positions. Furthermore, without such interpolation, the data will only be of the measured positions, and the 3D model will not be smooth, reducing the useful value of the 3D model.

[0013] When such a 3D model is used, depending on the measurement location, the exact size cannot be determined, which may cause discrepancies when used for custom-made products. In particular, when estimating the overall shape of the 3D model, the estimation is based on the general shape of a human being, so that, for example, when a part of the body has changed due to various types of patients such as hallux valgus, a fracture, or labor, the difference between the actual body shape of the user and the 3D model becomes even larger. Therefore, in the present application, a model for correcting the size is generated. In particular, such a model is generated for each business operator and for each group of users who use the business operator.

[0014] [1. Configuration of information processing system] An information processing system 1 shown in Fig. 1 will be described. As shown in Fig. 1, the information processing system 1 includes a business operator terminal 10, a first user terminal 20, a second user terminal 30, and an information processing device 100. The business operator terminal 10, the first user terminal 20, the second user terminal 30, and the information processing device 100 are connected to each other via a predetermined communication network (network N) so as to be communicable by wire or wirelessly. Fig. 1 is a diagram showing an example of the configuration of the information processing system 1 according to an embodiment.

[0015] The business operator terminal 10 is an information processing device used by a business operator (vendor) who wishes to properly grasp the body size of a user. A business operator using the business operator terminal 10 is, for example, a business operator who has applied for a service provided by the information processing device 100. For example, a business operator using the business operator terminal 10 is a business operator who sells clothes, used clothes, etc. in a predetermined online shopping mall. The business operator terminal 10 may be any device as long as it can realize the processing in the embodiment. In addition, the business operator terminal 10 may be a device such as a smartphone, a tablet terminal, a notebook PC, a desktop PC, a mobile phone, or a PDA.

[0016] The first user terminal 20 is an information processing device used by a user who provides the length of a line segment of a measurement target estimated from a three-dimensional model and the actual measured value of the length of the line segment of the measurement target in order to learn an estimation model that estimates the user's body size. The user who uses the first user terminal 20 is, for example, a collaborator for data collection who has a cooperative relationship with a business operator. The first user terminal 20 may be any device that can realize the processing in the embodiment. In addition, the first user terminal 20 may be a device such as a smartphone, a tablet terminal, a notebook PC, a desktop PC, a mobile phone, or a PDA.

[0017] The second user terminal 30 is an information processing device used by a user who uses the service provided by the information processing device 100. The user who uses the second user terminal 30 is, for example, an end user. The second user terminal 30 may be any device that can realize the processing in the embodiment. In addition, the second user terminal 30 may be a device such as a smartphone, a tablet terminal, a notebook PC, a desktop PC, a mobile phone, or a PDA.

[0018] The information processing device 100 is an information processing device intended to enable appropriate measurement of the body size of a user for each business operator, and may be any device capable of implementing the processes in the embodiment. The information processing device 100 is implemented, for example, by a server device or a cloud system. For example, the information processing device 100 issues an account in response to a subscription to a service of a business operator. Also, for example, the information processing device 100 provides various services to end users.

[0019] [2. An example of information processing] FIG. 2 is a diagram showing an example of information processing of the information processing system 1 according to the embodiment. In the following embodiment, the three-dimensional model is a model in which the overall size is estimated by measuring the size of a part. For example, the three-dimensional model according to the embodiment is a three-dimensional model in which the overall size of a user is estimated based on data acquired from a body size measurement garment that can measure the size of a specific part by being worn by the user. The three-dimensional model according to the embodiment may be a three-dimensional model of a first user or a three-dimensional model of a second user. The business operator V1 is a business operator who applies for the service according to the embodiment. The first user A1 is a user (cooperator) who has a cooperative relationship with the business operator V1 in data collection. The second user U1 is a user (end user) who uses the service provided by the information processing device 100. Hereinafter, the first user and the second user may be collectively referred to as "users" as appropriate. The range to be measured according to the embodiment may be any part of the user's body as long as it is a range that can be specified from the three-dimensional model, and may not be particularly limited. For this reason, it may be possible to set any part as the range to be measured for each business operator. Furthermore, the range to be measured according to the embodiment may be a position, and hereinafter, the range to be measured may be read as "the position to be measured" as appropriate.

[0020] When the information processing device 100 accepts an application for a service from the business operator V1, the information processing device 100 issues an account for the business operator V1 and provides the business operator V1 with application information for using the service (step S101).

[0021] The business entity V1 provides an application based on the application information provided by the information processing device 100 to the first user A1 who is a collaborator for data collection (step S102).

[0022] The first user A1 measures his / her body size and provides the measurement result to the business operator V1 via an application based on the application information provided by the business operator terminal 10 (step S103). For example, the first user terminal 20 transmits the measurement result of the body size of the first user A1 to the business operator terminal 10.

[0023] When the business operator terminal 10 acquires the measurement results of the body size of the first user A1, the business operator terminal 10 displays a three-dimensional model of the body type of the first user A1 based on the acquired measurement results via the application provided by the information processing device 100 (step S104). Fig. 3A is a diagram showing an example of the display of the three-dimensional model according to the embodiment.

[0024] When the business operator V1 specifies a range for measuring the length from the three-dimensional model displayed on the business operator terminal 10 via an application provided by the information processing device 100, the business operator terminal 10 accepts the range specification by the business operator V1 (step S105). FIG. 3B is a diagram showing an example of range specification according to an embodiment. The business operator V1 may specify the range from the image on the left side, or may specify the range from the input field on the right side. Note that in FIG. 3B, the range from the wrist to the shoulder of the right arm of the three-dimensional model is selected, so this range is specified.

[0025] The business operator terminal 10 estimates the length of the line segment within the range specified from the three-dimensional model via the application provided by the information processing device 100 (step S106). In addition, the business operator V1 measures the actual value of the length of the line segment that is the measurement target of the first user A1 (for example, by measuring with a hand tape measure, etc.) and inputs the measurement result to the business operator terminal 10, whereby the business operator terminal 10 accepts the actual value of the length of the line segment that is the measurement target of the first user A1.

[0026] The information processing device 100 acquires information indicating the range to be measured designated by the business operator V1 and data on the length of the line segment to be measured of the first user A1 (the estimated value of the length of the line segment estimated from the three-dimensional model and the actual measured value of the length of the line segment to be measured) (step S107). Then, the information processing device 100 trains an estimation model that estimates the length of the line segment to be measured from the three-dimensional model so that the length of the line segment estimated from the three-dimensional model becomes the actual measured value of the length of the line segment to be measured (step S108). Note that the information processing device 100 may train the estimation model by acquiring information indicating the range to be measured designated by the business operator V1 and data on the length of the line segments to be measured of multiple first users. For example, the information processing device 100 may train the estimation model so as to output the actual measured value of the length of the line segment to be measured when the range to be measured designated by the business operator V1 and the measured value of the length estimated from the three-dimensional model are input. That is, the information processing device 100 may learn an estimation model using information indicating the range to be measured designated by the business operator V1 and data on the length of the line segments of the measurement target of a plurality of first users as teacher data. The information processing device 100 may also learn an estimation model for each business operator, or may learn an estimation model for each purpose. Even for the same business operator, the measurement condition may be different when, for example, measuring the length of the waist part when tailoring a suit jacket and when measuring the length of the waist part when tailoring pants for a suit. For example, when the pants are measured more closely than the jacket, it is assumed that the measurement result of the length of the waist part of the pants tends to be thinner than the measurement result of the length of the waist part of the jacket. The information processing device 100 may learn an estimation model that estimates the length of the line segment of the measurement target used for a purpose from a three-dimensional model by acquiring data on the length of the line segment of the measurement target of the first user, which is length data according to the purpose used for a specific purpose.

[0027] For example, when the information processing device 100 proposes to the second user U1 a size suitable for the second user U1 among the sizes of products sold by the business V1, the information processing device 100 provides the second user U1 with a service of estimating the length of a line segment of a measurement target from a three-dimensional model using an estimation model that estimates the length of a line segment of a measurement target specified by the business V1 among estimation models learned for each business (step S109). For example, once the second user U1 measures his / her own body size once, the information processing device 100 stores the measurement information and provides a service that allows the second user U1 to use the services of each business.

For example, the acquisition unit 131 acquires data on the length of the line segment to be measured that is estimated from the three-dimensional model. Also, for example, the acquisition unit 131 acquires data on the actual measurement value of the length of the line segment to be measured.

[0064] (Generation unit 132) The generation unit 132 receives the 3D model of the user as an input and generates an estimation model that estimates the length of a line segment of a measurement target specified for each business operator. For example, the generation unit 132 generates an estimation model for each business operator based on teacher data collected by collecting teacher data for each business operator. The generation unit 132 may also generate an estimation model that estimates the length of a line segment of a measurement target for each purpose.

[0065] (Learning Section 133) The learning unit 133 trains the estimation model generated by the generation unit 132 so that the length of the line segment estimated from the three-dimensional model of the first user becomes the actual measurement value of the length of the line segment of the measurement target of the first user. The learning unit 133 may also train the estimation model generated by the generation unit 132 so that the length of the line segment estimated from the three-dimensional model of the second user becomes the actual measurement value of the length of the line segment of the measurement target of the second user. The learning unit 133 may train the estimation model every time the amount of teacher data increases, or may train the estimation model every time the number of data of the teacher data reaches a predetermined threshold value for a predetermined period. In this way, the learning unit 133 may repeatedly perform training to improve the accuracy of the estimation model. The number of teacher data may be set for each business operator, and the business operator may freely change the number of teacher data to increase if it is necessary to improve the accuracy. The learning unit 133 may also train the estimation model including physical characteristics such as place of origin and race, and external characteristics such as measurement time period. For example, in the case of external features, since swelling is more likely in the morning than in the evening, the learning unit 133 may generate an estimation model for mornings and an estimation model for evenings separately and perform learning on them separately. Also, in the case of physical features, since the legs of athletes are thicker than the legs of non-athletes, the learning unit 133 may generate an estimation model for athletes and an estimation model for non-athletes separately and perform learning on them separately.

[0066] (Estimation part 134) The estimation unit 134 estimates the length of a line segment in the range of the measurement target specified by a specific business operator from the three-dimensional model of the second user, using the estimation model learned by the learning unit 133. For example, the estimation unit 134 estimates the length of a line segment in the range of the measurement target specified by a business operator according to the service selected by the second user.

[0067] (Provider 135) The providing unit 135 transmits various information to the business operator terminal 10, the first user terminal 20, and the second user terminal 30. For example, the providing unit 135 provides information on the length of the line segment estimated by the estimating unit 134 to the second user.

[0068] [7. Information processing flow] Next, the procedure of information processing by the information processing system 1 according to the embodiment will be described with reference to Fig. 10 and Fig. 11. Fig. 10 and Fig. 11 are flowcharts showing the procedure of information processing by the information processing system 1 according to the embodiment.

[0069] As shown in FIG. 10, the information processing device 100 acquires, from the business operator, information indicating a range within which the length is to be measured from the three-dimensional model of the user, and data on the length of the line segment to be measured (step S201).

[0070] The information processing device 100 trains an estimation model that estimates the length of the line segment of the measurement target from the three-dimensional model so that the length of the line segment estimated from the three-dimensional model becomes the actual measured value of the length of the line segment of the measurement target (step S202).

[0071] The information processing device 100 provides an estimation result estimated using the estimation model (step S203).

[0072] As shown in FIG. 11, the information processing device 100 acquires information indicating the range to be measured for length from the user's three-dimensional model, and data on the length of the line segment to be measured, which is length data according to a specific purpose to be used for a specific purpose (step S301).

[0073] The information processing device 100 trains an estimation model that estimates the length of a line segment of a measurement object used for a purpose from a three-dimensional model so that the length of the line segment estimated from the three-dimensional model becomes the actual measured value of the length of the line segment of the measurement object (step S302).

[0074] The information processing device 100 provides an estimation result estimated using the estimation model (step S303).

[0075] 8. Application Examples The above embodiment is expected to be particularly applicable when, for example, the line segment information of each part of the body has changed due to an illness or the like. For example, it may be applied to estimating the length of a line segment of a measurement target of a patient with a symptom in which a specific part is swollen due to an illness or the like (for example, a patient with a symptom in which lymph fluid accumulates under the skin and causes swelling). By applying it to estimating the length of a line segment of a measurement target of a user in which only the line segment information of a specific part has changed due to an illness or the like, it becomes possible to appropriately estimate the length of the line segment of the measurement target of such a user. In addition, since it is possible to estimate the length of a line segment of a measurement target of a user in which only such a specific part is swollen unlike normal, it is also possible to apply it to the production of costumes or costumes for such users. Note that such an application example is merely an example and need not be particularly limited.

[0076] [9. Effects] As described above, the information processing device 100 according to the embodiment includes the acquisition unit 131 and the learning unit 133. The acquisition unit 131 acquires, from the business operator, information indicating a range to be measured for length from a 3D model of the user and data on the length of the line segment to be measured. The learning unit 133 trains an estimation model that estimates the length of the line segment to be measured from the 3D model such that the length of the line segment estimated from the 3D model becomes the actual measured value of the length of the line segment to be measured.

[0077] As a result, the information processing device 100 according to the embodiment acquires information indicating the range to be measured and data on the length of the line segment to be measured from the business operator and trains an estimation model, thereby enabling appropriate measurement of the user's body size for each business operator.

[0078] The data acquired by the acquisition unit 131 includes information indicating the length of a line segment estimated from a three-dimensional model and information indicating the actual measured value of the length of the line segment to be measured, and is collected for each user.

[0079] This allows the information processing device 100 according to the embodiment to appropriately improve the accuracy of the estimation model for estimating the body size of the user.

[0080] In addition, a three-dimensional model is a model whose overall size is estimated by measuring the sizes of a portion of it.

[0081] This allows the information processing device 100 according to the embodiment to appropriately generate a three-dimensional model.

[0082] In addition, the user is a collaborator who provides the length of the line segment of the measurement target estimated from the three-dimensional model and the actual measured value of the length of the line segment of the measurement target in order to train the estimation model.

[0083] As a result, the information processing device 100 according to the embodiment can appropriately improve the accuracy of an estimation model for estimating the body size of a user based on the data of the user who is a collaborator in data collection.

[0084] Furthermore, the learning unit 133 learns the lengths of the line segments of the measurement target estimated from the three-dimensional models of a plurality of users and the actual measured values ​​of the lengths of the line segments of the measurement target as teacher data.

[0085] As a result, the information processing device 100 according to the embodiment can appropriately improve the accuracy of the estimation model for estimating the body size of the user by learning the training data.

[0086] Furthermore, the acquisition unit 131 acquires information indicating a range determined by the business operator specifying a range to be measured on the user interface on which the three-dimensional model is displayed.

[0087] As a result, the information processing device 100 according to the embodiment can specify the range to be measured on the user interface, thereby promoting improvement in usability.

[0088] In addition, the information processing device 100 according to the embodiment further has an estimation unit 134 that estimates the actual measured value of the length of the line segment of the measurement target of the target user by inputting the length of the line segment of the measurement target estimated from a three-dimensional model of a target user different from the user into an estimation model learned by the learning unit 133.

[0089] As a result, the information processing device 100 according to the embodiment can appropriately estimate the length of the line segment to be measured for the target user by using the trained estimation model.

[0090] The user is a user who has edema in the measurement subject due to a predetermined symptom. The target user is a user who has edema in the measurement subject due to a predetermined symptom.

[0091] As a result, the information processing device 100 according to the embodiment can appropriately estimate the length of the line segment of the measurement target of the target user even if the target user has edema and there is swelling in the range of the measurement target.

[0092] [10.
