Description

  The present invention relates to a virtual 3D body creation system used for creating clothes according to a customer's request, and a custom-made pattern creation system including the virtual 3D body creation system.

  Conventionally, when creating custom-made clothes, the store clerk measures the dimensions of the customer's body, and based on this, the pattern is created and modified to create the clothes.

  Here, when measuring the figure of the customer (subject), the store clerk directly measured the bust etc. with a measure. However, there are problems such as that skill is required for accurate measurement at the major, that there are differences depending on the person to measure, and that some customers hate to be touched by others.

  On the other hand, if the customer's body shape is measured by a 3D scanner system (also referred to as “three-dimensional scanner system”), the customer's body shape can be accurately measured. However, the 3D scanner system has about 10 million, and there is a problem that it is difficult to install in each store. Further, when measuring with a 3D scanner system, there is a problem that a hole is formed in the shadowed portion of the measurement data or the boundary portion is broken.

  Therefore, the present invention has been devised, and the present invention can easily and inexpensively obtain customer 3D body data according to the customer's body shape without installing a 3D scanner system for each store. Providing a custom 3D body creation system and a custom 3D body creation system that can produce paper patterns that match the customer's body shape without using a 3D scanner system. The purpose is to do.

The following description focuses on independent claims.
(Virtual 3D body creation system)
The virtual 3D body creation system according to claim 1 is used to create a custom-made garment, and includes a photographing means for photographing a customer from the front and side, and a customer based on a photographing result of the photographing means. 2D showing silhouettes from the front and side of the customer (2D, the same applies to the present specification and claims) Silhouette extracting means for creating silhouette body data, and customer 2D extracted by the silhouette extracting means Reference point extraction means for extracting reference point data from silhouette body data, and a plurality of reference body 3D bodies obtained in advance by measurement using a 3D scanner system based on the reference point data extracted by the reference point extraction means From the 3D body database storing data, the customer 2D silhouette body data and Approximate data selection means for selecting similar reference body 3D body data, and deformation means for deforming the approximate reference body 3D body data based on the reference point data extracted by the reference point extraction means. It is characterized by that.

  According to a second aspect of the present invention, there is provided a virtual 3D body creation system that captures customer 2D silhouette body data indicating 2D silhouette body data from the front and side of a customer based on a photographing result of photographing the customer and a photographing result of the photographing means. From a 3D body database that stores a plurality of reference body 3D body data obtained in advance by measurement using a 3D scanner system based on the silhouette extracting means to be created and the 2D silhouette body data extracted by the silhouette extracting means Approximation data selection means for selecting the customer 2D silhouette body data and the approximate reference body 3D body data, and transforming the approximate reference body 3D body data based on the 2D silhouette body data extracted by the silhouette extraction means And having deformation means to It is a symptom.

  According to the virtual 3D body creation system having the above-described configuration, the customer 2D silhouette body data is obtained by converting the photographing results from the front and side of the customer into a silhouette. Thereafter, the reference body 3D body data that is most similar to the customer 2D silhouette body data is selected from the reference body 3D body data obtained in advance by measurement using the 3D scanner system and stored in the 3D body database. Thereafter, the reference body 3D body data is deformed based on the 2D silhouette body data. For this reason, in creating customer 3D body data, there is no difficulty in deformation. Therefore, 3D body data conforming to the customer's body shape (matching with the customer's body shape) can be obtained without using the 3D scanner system. Here, when trying to obtain various customer 3D body data with only one 3D body data, the deformation should theoretically work, but in reality, the deformation is impossible and does not match the customer's body shape. The inventor of this application has confirmed that it becomes body data.

The virtual 3D body creation system according to the third to fifth aspects refers to at least one of the first or second aspect and exhibits the same operation as the virtual 3D body creation system according to the first or second aspect.
(Custom-made pattern making system)
In order to achieve the object, a custom-made pattern making system described in the claims is obtained from the virtual 3D body creating system according to any one of claims 1 to 5 and the virtual 3D body creating system. And a paper pattern creating means for creating a paper pattern based on the customer 3D body data.

  According to the made-to-order pattern making system configured as described above, since the customer 3D body data conforming to the customer's body shape can be obtained without using the 3D scanner system, the pattern making means is based on such data. Create a pattern.

  According to the virtual 3D body creation system of the present invention, body data equivalent to the case of using the 3D scanner system can be obtained without installing the 3D scanner system for each store. In other words, there is an effect that it is possible to easily and inexpensively obtain customer 3D body data according to the customer's body shape without installing a 3D scanner system for each store. Further, when the customer's body shape is measured by the 3D scanner system, the correction is required because the boundary portion is broken or a hole is formed. However, this correction work can be omitted.

  On the other hand, the made-to-order pattern making system of the present invention has an effect that a pattern conforming to the customer's body shape can be manufactured at low cost without using a 3D scanner system.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, an example (example) of a preferred embodiment of the present invention will be described with reference to the accompanying drawings. Of course, the technical scope of the present invention is not limited to the following examples.

  FIG. 1 is a schematic diagram of a tailor-made system 100, and FIG. 2 is a diagram illustrating processing of the tailor-made system. As shown in FIG. 1, the made-to-order system 100 includes a camera 110 and a personal computer (hereinafter referred to as “store side PC”) 120 installed in each store A, B, C (three in the figure). ), A personal computer (hereinafter referred to as “administrator-side server PC”) 130 serving as a server installed on the administrator K side, and a personal computer (hereinafter referred to as “administrator-side server PC”) 130 installed in each factory X, Y, Z. "Factory PC") 140 (three in the figure) are connected by the Internet I. The virtual 3D body creation system according to claims 1 to 5 of the claims includes a camera 110, a store side PC 120, and an administrator side server PC 130, and the claim 3 of the claims. The custom-made pattern making system includes a camera 110, a store-side PC 120, an administrator-side server PC 130, and a factory-side PC 140. Of course, the administrator-side server PC 140 may be the same PC as the store-side PC 120, or may be a PC installed in the same location (specifically, in the same store). Similarly, the factory-side PC 120 may be the same PC as at least one of the store-side PC 120 and the administrator-side server PC 130, or may be a PC installed at the same location.

  The camera 110 is installed in each of the stores A, B, and C, and is used to capture images of customers (subjects) who have visited the stores A, B, and C. (Hereinafter referred to as “Claims”)).

  Photographing of the customer by the camera 110 is performed in front of a plain wall or screen. Here, by photographing only the lattice-shaped calibration screen in advance, it becomes possible to grasp the degree of distortion of the lens of the camera 110 and to correct the image photographed by the camera 110. This image correction data is stored in the storage unit of the store-side PC 120 described later. Once the calibration screen is photographed, this is basically necessary unless the distance between the camera 110 and the subject is changed, the lens of the camera 110 is changed, or the camera 110 itself is changed. There is no. Of course, the camera 110 may be a digital camera or an analog camera. In the case of an analog camera, it may be read by a scanner (not shown).

  The store side PC 120 includes an arithmetic processing unit (not shown), a storage unit (not shown), a display unit (not shown), an operation unit (not shown), and a communication control unit (not shown). The image data of the front view and the side view of the customer photographed by the camera 110 is captured, the captured image data is converted into a silhouette to create customer 2D silhouette body data, and the customer 2D silhouette body data More reference point data is extracted. That is, the store-side PC 120 corresponds to the customer 2D silhouette creation unit and the reference point extraction unit described in the claims.

  Next, with reference to FIG. 3 to FIG. 5, the process executed on the store side PC 120 will be specifically described. First, a process for creating customer 2D silhouette body data from photographed image data showing the front and side surfaces of the customer photographed by the camera 110 will be described in detail.

  In creating the customer 2D silhouette body data, first, using the correction data, the captured image data stored in the storage unit of the store side PC 120 is corrected. That is, the distortion caused by the camera lens is corrected. Next, 2D silhouette body data is created based on the contrast ratio with the background.

  Details of how to create 3D body data from 2D silhouette body data will be described later, but in each store A, B, and C, it is only necessary to install the camera 110, and a large 3D scanner system is installed. No need to do. Thereby, the three-dimensional body data of the customer (subject) can be manufactured inexpensively and easily.

  Next, a specific example of extracting a reference point from 2D silhouette body data will be described. First, the front 2D silhouette body data is scanned horizontally from above to derive the highest part (head vertex) and the lowest part (floor point). Next, the magnification of the front 2D silhouette body data is calculated from the height input via the operation unit. Here, the X axis is a vertical line passing through the head apex, that is, the center line of the body.

  Thereafter, a combination of background part-body part-background part is searched, and the crotch point is derived. For derivation of the crotch point, when the front 2D silhouette body data is scanned horizontally from below, the background part-body part-background part-body part-background part is obtained. When this is raised, the position immediately before becoming the background part-body part-background part becomes the position of the crotch point derived. However, if there is a hand below the crotch point, there is a possibility that hand data may enter outside the above point, so it is assumed that there is a crotch point near the X axis derived in the previous section, and the hand data is exclude.

  Thereafter, a side neck point (also referred to as a side neck point, hereinafter referred to as “SNP”) is derived. It scans from the X axis of the body to the left and right in the upper third (1/3) part of the front 2D silhouette body data. In the vicinity of the center line, the background part is the body part from the top, but when moving left and right, there is a place that becomes the background part-body part-background part-body part. And the place of the background pinched | interposed into a body part becomes a SNP.

  Then, shoulder points are derived. From the SNP, the front view is scanned horizontally from top to bottom. From the right, there is a point of background part-body part-background part, but the body part gradually increases. When the amount of increase is examined, the point at which the amount of increase decreases is the shoulder point.

  Furthermore, a side point is derived. If the above shoulder point scanning is continued, there will be a place of background part-body part-background part-body part-background part-body part-background part. Here, the place of the background sandwiched between the body parts is a side point. However, it is not always the case that there is a side at a symmetrical point, so that a point at which either side is derived first is considered.

  As described above, the reference point can be easily derived by scanning the front 2D silhouette body data and detecting the combination of the background portion and the body portion. In particular, when compared with the case of directly deriving three-dimensionally from the 3D body data obtained from the three-dimensional scanner system, there is a remarkable effect. Of course, if the reference point cannot be automatically derived, it can also be derived by manual input.

  Next, the search for the reference point of the body using the side surface 2D silhouette body data will be described. First, the hip point is derived. The position of the crotch point previously derived from the front 2D silhouette body data is projected onto the side 2D silhouette body data. Then, scanning is performed within 30 cm upward from the crotch point position projected on the side surface 2D silhouette body data, and the position that protrudes most backward (the most convex position) is the hip point.

  Next, a bust point is derived. The position of the shoulder point previously derived from the front 2D silhouette body data is projected onto the side 2D silhouette body data. Then, scanning is performed within 30 cm downward from the shoulder point position projected on the side surface 2D silhouette body data, and the position that protrudes most forward is the bust point.

  Furthermore, a waist point is derived. Scan between the bust point and the hip point previously derived from the side 2D silhouette body data. The place where the length of the body part is the narrowest (the most recessed position) is the waist point. This completes the derivation of all reference points.

  As described above, the reference point can be easily derived by scanning the side surface 2D silhouette body data and detecting the unevenness.

  Of course, if the reference point cannot be automatically derived from the front 2D silhouette body data or the side surface 2D silhouette body data, the reference point can be derived by manual input. Then, these 2D silhouette body data and reference point data are transmitted to the administrator-side server PC 130 via the communication control unit.

  Further, in the customer-side PC 120, the customer's favorite clothing is virtualized to the customer 3D body data (body data conforming to the customer's body shape (very close)) created by the administrator-side server PC 130, which will be described in detail later. Try on. If clothing is finally determined, clothing information data (information data on shape, pattern, size, fabric, etc.) is transmitted again to the administrator-side server PC 130 via the communication control unit.

  Similarly to the store-side PC 120, the manager-side server PC 130 also includes an arithmetic processing unit (not shown), a database (a kind of storage means, not shown), a display unit (not shown), and an operation unit (not shown). The communication control unit (not shown) is configured to create customer 3D body data from the customer 2D silhouette body data transmitted from the store-side PC 120, and the created customer 3D body data to the store-side PC 120. It is transmitted (including enabling browsing from the store side PC 120). The administrator-side server PC 130 corresponds to the approximate data selection means, deformation means, and pattern creation means in the claims. The approximate data selection means and the deformation means can be realized by the customer-side PC 120, and the pattern creating means can also be realized by the factory-side PC 140.

  Here, a method (procedure) for creating customer 3D body data from customer 2D silhouette body data will be described. First, using a three-dimensional scanner system, three-dimensional measurement of the body (body shape) of a plurality of people of all ages who are the basis of deformation is stored in the database of the administrator server PC 130. Keep it. Next, the reference body stored in the database based on the customer 2D silhouette body data and the reference point data transmitted from the store side PC 120, and also the height data, gender data and age data input via the operation unit. The closest body data is selected from the 3D body data. Here, in order to perform selection processing based on the 2D silhouette body data, first, the height of the 2D silhouette body data is adjusted to the height of the reference body 3D body data based on the height data (conversely, the reference body 3D body data). May be adjusted to the height of 2D silhouette body data). Next, it is executed based on the ratio of the overlapping area (at least one of each part or the whole) and the non-overlapping area between the 2D silhouette body data and the reference body 3D body data. On the other hand, the selection process based on the reference point data is performed based on the body type information obtained from the reference point of the 2D silhouette body data. As a specific example, the waist width (bust width, bust width, obtained by applying the waist point (bust point, hip point) obtained from the silhouette body data of at least one of the front and side surfaces to the other silhouette body data, etc. Hip width) is compared with the body shape information of the reference body 3D body data. The body type information includes the length around the neck obtained from the length between both SNPs and the shoulder width calculated from both shoulder points. Then, based on both comparison results, the closest reference body 3D body data is selected.

  Further, the selected reference body 3D body data is deformed based on at least one of the above-described customer 2D silhouette body data and reference point data. Thereby, 3D body data (customer 3D body data) conforming to the customer's body shape (in other words, very close) can be obtained. Then, the transformed 3D body data is sent back to the store-side PC 120 as the transmission source.

  In this way, it is possible to obtain body data according to the customer's body shape by installing a 3D scanner system only in one place (without installing it at each store), and making the entire system inexpensive. It becomes possible. In addition, by measuring the bodies of people with a wide range of ages and various body shapes in this way, even if deformation processing is performed, unreasonable deformation can be avoided, and very approximate 3D body data can be obtained without falling down theoretically. It becomes possible. Further, when a body is measured using a three-dimensional scanner system, correction is required such that the boundary portion collapses or a hole is formed, but such correction work is not required every time. Furthermore, if the body data previously measured by a third party using a three-dimensional scanner system can be obtained, the three-dimensional scanner system can be eliminated from the entire system.

  Furthermore, when the manager-side server PC 130 receives clothing information data from the customer-side PC 120, a pattern (customer) corresponding to the customer based on the clothing information data, customer 3D body data, and reference point data is received. Dedicated paper pattern) data is created. Specifically, one standard pattern paper data is stored in advance in the storage unit in association with a plurality of reference body 3D body data having similar body shapes, and the customer 3D body data is received when the clothing information data is received. And the reference body 3D body data are compared. Then, based on the comparison result (difference), the standard pattern paper data is corrected, more specifically, the standard pattern paper data is partially or entirely enlarged or reduced (in other words, similar). The customer-specific paper pattern data is created. Therefore, it is possible to realize a pattern conforming to the customer's body shape at low cost and easily (simple program).

  The factory-side PC 140 issues a command to the pattern making device (not shown) and the clothing manufacturing device (not shown) based on the sewing information (clothing information data and corresponding customer-specific pattern data) sent from the administrator-side server PC 130. It is something to be issued. The clothes created at the factory are delivered to customers (consumers).

  Next, with reference to FIG.1 and FIG.2, the process performed in this custom-made system 100 is demonstrated in order.

  First, in the store A (or B, C), the front and side surfaces of the customer (subject) are photographed by the camera 110 (D1). Thereafter, the store side PC 110 extracts a silhouette from the photographing result of the camera 110 (D2). Thereafter, the store side PC extracts the reference point from the customer 2D silhouette body data (D3). Thereafter, the customer 2D silhouette body data and the reference point data are transmitted from the store-side PC 120 to the manager-side server PC 130, and the manager-side server PC 130 creates customer 3D body data (D4, D5). Thereafter, when the customer 3D body data is transmitted to the customer side PC 120 and the clothing is selected, the clothing information data is transmitted from the customer side PC 120 to the manager side server PC 130. Thereafter, the administrator-side server PC 130 modifies the standard pattern based on the difference between the standard 3D body data and the customer 3D body data, and creates a customer-specific pattern (D6). Thereafter, the customer-specific pattern data is transmitted by the administrator-side server PC 130 to the factory-side PC 140 installed in any one of the factories X, Y, and Z.

  The present invention has been described based on the embodiments. However, it goes without saying that the above embodiments can be variously improved and modified without departing from the spirit of the present invention. These modifications are also included.

  For example, in the above-described embodiment, only the lattice-shaped calibration screen is photographed in advance before the customer 110 photographs with the camera 110. However, such precondition processing is not necessarily performed, and the customer may be photographed together with the calibration screen, or the customer may be photographed together with the predetermined mark. As a result, it is possible to take a picture without considering the distance between the camera 110 and the customer (without worrying about it). In this case, however, it is necessary to input data on the shape and size of the grid of the calibration screen and the shape and size of the predetermined mark.

  Further, in the above embodiment, the creation of the customer 3D body data is based on the 2D silhouette body data and the reference point data (excluding data input via the operation unit from consideration). It is executed by performing selection processing and transformation processing. However, the reference body 3D body data selection process and the deformation process may be executed based on only one of the 2D silhouette body data and the reference point body data. Here, if the reference body data is selected and deformed based only on the 2D silhouette body data, for example, when the customer is photographed by the photographing means, the photographing process is performed without photographing from the front and the side. Can be simplified. Specifically, there is an advantage that it is only necessary to shoot from only the front side, only the side surface, and diagonally (not only laterally diagonally, but also diagonally upward and downward). Of course, in addition to the front and side surfaces, oblique and upward directions may be taken. Furthermore, when the reference body data is selected and deformed based only on the 2D silhouette body data, the process of extracting the reference point (the process of D3 in FIG. 2) may be omitted.
