To do. Here, the user surface data is an example of object shape data. The user surface data includes the reference position data of the positioning plate 12, but does not include (converted) the shape data of the positioning plate 12.

  In addition, the computer 14 synthesizes, for example, blank surface data, which is data indicating at least the shape of an appendage that is a ridge, and user surface data. Here, an appendage is any tangible or intangible thing added to an object, and includes a human body and a part of the body. For example, the appendage can be an instrument worn on the body such as a bag, clothes, a decorative window, a fictional character, or a face or body of a person different from the person (user) of the face 16 that is the object. Blank surface data is an example of additional shape data. In the following, an example of an addendum will be described.

  In the computer 14, a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, and a RAM (Random Access Memory) 33 are connected to each other by a bus 34.

  An input / output interface 35 is further connected to the bus 34. The input / output interface 35 includes an input unit 36 including a keyboard, a mouse, and a microphone, an output unit 37 including a display and a speaker, a storage unit 38 including a hard disk and a nonvolatile memory, and a communication unit 39 including a network interface.

The program can be installed in the computer 14 by being received by the communication unit 39 via a wired or wireless transmission medium and stored in the storage unit 38. In addition, the program can be installed in the computer 14 in advance by storing it in the ROM 32 or the storage unit 38 in advance.

  FIG. 3 is a block diagram illustrating an example of a functional configuration realized in the computer 14 that executes the program. That is, when the computer 14 executes the program, the communication control function 61, CAD function 62, CAM function 63, polygon data database (DB) 64 (hereinafter referred to as polygon data DB 64), surface data database (DB) 65 (hereinafter referred to as polygon data DB 64). , Surface data DB 65) and machining program database (DB) 66 (hereinafter referred to as machining program DB 66).

  The communication control function 61 controls the communication unit 39 that is a network interface, and controls communication with the scanner 11 or the machining center 15 via the network 13. The CAD function 62 is realized, for example, by executing a CAD program such as Rapid Form XOR / Redesign (trademark), and generates data describing a shape in a virtual three-dimensional space in accordance with a user operation. .

  The CAD function 62 includes a conversion unit 71 and a synthesis unit 72. The conversion unit 71 converts the data of the position in the three-dimensional space of each point on the surface of the user's face 16 as a target obtained by measurement into surface data expressed by a surface. The synthesizing unit 72 synthesizes the surface data that expresses the shape of the eyelid, which is an additive, with a surface, and the surface data that expresses the shape of the user's face 16, which is an object, with the surface.

  The CAM function 63 generates a machining program for instructing machining in the machining center 15 from data in which a shape is described in a virtual three-dimensional space.

  The polygon data DB 64, the surface data DB 65, and the machining program DB 66 are built directly on a file system provided by the operating system or by a database management system. The polygon data DB 64 records data on the position of each point on the surface of the object in the three-dimensional space. That is, the polygon data DB 64 records the polygon data 73 supplied from the scanner 11 and indicating the position in the three-dimensional space of each point on the surface of the user's face 16 obtained by measuring the user's face 16. .

  The surface data DB 65 records data indicating the shape by at least a surface. That is, the surface data DB 65 records surface data that is generated by the CAD function 62 or synthesized and that expresses the shape with a surface. More specifically, the surface data DB 65 includes blank surface data 74 that expresses the shape of the eyelid as an appendage by a surface, and user surface data 75 that expresses the shape of the user's face 16 as an object by a surface. , And finished product surface data 76 representing the shape of the face of the user who has been wrinkled with a face. The user surface data 75 is generated by conversion from the polygon data 73 by the conversion unit 71 of the CAD function 62, and the finished product surface data 76 is blanked by the combining unit 72 of the CAD function 62. It is generated by combining the surface data 74 and the user surface data 75.

  The machining program DB 66 records a machining program for instructing the machining center 15 to perform machining. More specifically, the machining program DB 66 records a blank machining program 77 and a finished product machining program 78. The blank machining program 77 is a machining program for forming a shape of a ridge that is an appendage generated from the blank surface data 74 by the CAM function 63. The finished product processing program 78 converts the shape of the user's face 16 that is the target object into the blank that is generated from the finished product surface data 76 by the CAM function 63 and in which the shape of the wrinkle that is an additive is previously formed. This is a machining program for molding.

  FIG. 4 is a diagram for explaining the production of blanks and finished products by the production system 1. First, the CAM function 63 uses a tool in each axis of a predetermined coordinate system such as a Cartesian coordinate system from blank surface data 74 that is recorded in the surface data DB 65 and expresses the shape of the ridge that is an addition by a surface. The blank processing program 77 for forming the shape of the ridge which is an appendage is generated by instructing the position of the material 91 or instructing the position of the material 91 made of metal or resin. As shown in FIG. 4, in the blank surface data 74, a sufficient volume is secured in the portion where the shape of the face 16 as the object is formed in consideration of the engraving allowance.

  The generated blank machining program 77 is recorded in the machining program DB 66 and transmitted to the machining center 15 via the network 13.

  The machining center 15 uses the blank machining program 77 to cut the material 91 to form the shape of the ridge, which is an additive, into the blank 92. That is, the machining center 15 drives a built-in servo motor according to a blank machining program 77 that describes the operation of the cutting edge of a cutting tool such as a mill on the basis of a three-dimensional coordinate axis, thereby cutting a cutting tool or material 91. To blank the blank 92 from the material 91.

  Next, when the scanner 11 measures the position in the three-dimensional space of each point on the surface of the face 16 that is projected into the hole of the positioning plate 12, polygon data 73 indicating the position of each point is obtained via the network 13. It is sent to the computer 14. Then, the computer 14 controls the communication unit 39 as a network interface by the communication control function 61 and receives the polygon data 73. The computer 14 records the received polygon data 73 in the polygon data DB 64.

  The conversion unit 71 of the CAD function 62 converts the polygon data 73 recorded in the polygon data DB 64 into user surface data 75 that expresses the shape of the user's face 16 as a target by a surface. For example, the conversion unit 71 detects a boundary (for example, a discontinuous point) of a surface represented by a set of points indicated by the polygon data 73, and indicates the polygon data 73 for each surface delimited by the detected boundary. The polygon data 73 is converted into user surface data 75 by generating data representing the same surface as the surface represented by a part of the set of points. Alternatively, for example, the conversion unit 71 converts the polygon data 73 into user surface data 75 by converting the polygon data 73 into voxel representation and generating data representing the surface represented by the voxel. In addition, after the polygon data 73 is corrected by a CG (Computer Graphics) program such as Free Form (trademark) so as to deform the shape expressed by the polygon data 73, the conversion unit 71 corrects the corrected polygon data 73. May be converted into user surface data 75.

  The CAD function 62 records user surface data 75 in the surface data DB 65.

  The synthesizer 72 of the CAD function 62 provides blank surface data 74 so that a person is wearing a beard, that is, the user's face 16 as an object is placed inside the addendum. And the user surface data 75 are combined to generate the finished product surface data 76. At this time, the synthesizer 72 adjusts the user surface data 75 so as to enlarge or reduce the shape of the user's face 16 that is the object in accordance with the shape of the eyelid that is the addition indicated by the blank surface data 74. Convert. Note that, in the synthesis of the blank surface data 74 and the user surface data 75, the data of the portion of the blank surface data 74 in which the shape of the face 16 that is the object is formed in consideration of the engraving margin is not used. .

  More specifically, in the blank surface data 74, reference positions (cross marks in FIG. 4) in a three-dimensional space are arranged in advance on the X axis and the Y axis. The reference position drawn as an image on the positioning plate 12 is included in the polygon data 73. Even when the polygon data 73 is converted into the user surface data 75, the user surface data is used as the reference position in the three-dimensional space. 75 (circles in FIG. 4). The combining unit 72 combines the blank surface data 74 and the user surface data 75 so that the reference position of the blank surface data 74 matches the reference position of the user surface data 75. By doing in this way, the position of the shape of the user's face 16 that is the object and the shape of the eyelid that is the additional object can be matched so that a person wears the eyelid. In this case, for example, the compositing unit 72 is configured so that the reference position of the user surface data 75 is arranged at a predetermined distance with respect to the reference position of the blank surface data 74. The blank surface data 74 and the user surface data 75 may be synthesized by giving priority to the shape of 16 and matching the shape of the eyelid as an addition to the shape. As described above, the combining unit 72 combines the blank surface data 74 and the user surface data 75 with reference to the reference position of the blank surface data 74 and the reference position of the user surface data 75.

  Note that the eyes and mouth of the user's face 16 can be detected and the eyes and mouth can be used as the reference position. That is, the feature point of the object may be detected and the detected feature point may be used as the reference position.

  More specifically, for example, the combining unit 72 matches the reference positions of the blank surface data 74 and the user surface data 75, and then performs blank surface data in the Z-axis direction orthogonal to the X-axis and the Y-axis. When the surface of 74 and the surface of the user surface data 75 overlap, of the surface portions of the blank surface data 74 and the user surface data 75 on the XY plane defined by the X axis and the Y axis. For each point, the blank surface data 74 and the user surface data 75 are synthesized so as to leave a portion of the surface away from the XY plane and delete the surface close to the XY plane. By doing so, the shape of the eyelid and the shape of the user's face 16 can be combined as in the case where the user wearing the eyelid is viewed from the front.

  Further, for example, a synthesis reference point (or plane) is determined in advance in three dimensions, and the synthesis unit 72 determines the surface of the overlapping blank surface data 74 depending on the distance from the synthesis reference point (or plane). The blank surface data 74 and the user surface data 75 are synthesized by leaving or deleting the portion and the surface portion of the user surface data 75.

  Further, for example, among the surfaces of the blank surface data 74, the surfaces to be left are defined in advance, and the combining unit 72 determines the surfaces to be left as the blank surface data 74 and the user surface data 75. The blank surface data 74 and the user surface data 75 are combined by combining the surfaces. Furthermore, for example, the priority order is defined for each surface of the blank surface data 74, and the combining unit 72 defines a predetermined priority order for the surface of the user surface data 75, and the priority order for each surface. Thus, the blank surface data 74 and the user surface data 75 are synthesized so as to determine the remaining surface portion of the overlapping surface portions.

  The CAD function 62 causes the surface data DB 65 to record the finished product surface data 76 obtained by combining the blank surface data 74 and the user surface data 75.

  The CAM function 63 indicates the position of the tool on each axis of a predetermined coordinate system such as an orthogonal coordinate system or the position of the blank 92 from the finished product surface data 76 recorded in the surface data DB 65. By doing so, a finished product processing program 78 for forming the shape of the user's face 16 as an object on the blank 92 is generated.

  If a machining program is generated directly from only the user surface data 75 and used for machining the blank 92, machining according to the shape of the appendage cannot be performed, so the boundary between the object and the appendage is unnatural. Moreover, in the machining center 15, troubles such as the cutting edge of a cutting tool such as a mill colliding with the blank 92 are likely to occur. Since the finished product processing program 78 is generated from the finished product surface data 76 obtained by synthesizing the blank surface data 74 and the user surface data 75, the shape of the object becomes unnatural. Moreover, the trouble at the time of the process from the blank 92 to the finished product 17 can be prevented.

  The generated finished product machining program 78 is recorded in the machining program DB 66 and transmitted to the machining center 15 via the network 13.

  The machining center 15 cuts the blank 92 using the finished product processing program 78 to shape the shape of the user's face 16 as the object into the blank 92, and the user's face 16 covered with the heel is formed. The completed product 17 is created. That is, the machining center 15 drives a built-in servo motor in accordance with a finished product machining program 78 that describes the operation of the cutting edge of a cutting tool such as a mill on the basis of a three-dimensional coordinate axis, thereby cutting a cutting tool or a blank. 92 is operated to cut the finished product 17 from the blank 92.
