1. Structure FIG. 1 is a diagram illustrating an appearance of a 3D scanner 1 according to an embodiment. The 3D scanner 1 is a three-dimensional modeling data generation device that photographs a subject and generates three-dimensional modeling data that is a three-dimensional model of the subject. The 3D scanner 1 generally uses a structure that forms a shooting room (booth or space) for shooting a subject, a group of sensors that shoot the subject, and three-dimensional modeling data using data acquired by these sensors. Has a computer device for generating. Each sensor group includes an image sensor and a distance sensor. The image sensor captures an image of a subject and outputs it as gradation data (image data) of a predetermined color component (for example, three colors of RGB) for each spatial unit (pixel). The distance sensor outputs the distance to the surface of the subject as distance data for each spatial unit (pixel). It can be said that the image sensor measures the color of the subject and the distance sensor measures the unevenness (surface shape).

  FIG. 1 mainly shows a structure that forms an imaging room. This structure has a frame (frame body) formed of a rod-shaped member, and a panel (plate material or decorative plate) fixed to the frame. The frame is a structure for giving mechanical strength to the 3D scanner 1 and for fixing the sensor group. The frame is made of metal, for example. The panel is a plate material for preventing the subject being photographed from being seen from the outside and improving the aesthetic appearance of the entire apparatus. The panel is formed of, for example, metal, resin, wood, paper, or a combination thereof.

  In this example, the 3D scanner 1 has a structure without a floor and a ceiling. As described above, the simple structure without the floor and the ceiling is easier to install or remove as compared with the structure having the floor and the ceiling.

  FIG. 2 is a diagram illustrating a frame structure of the 3D scanner 1. The 3D scanner 1 includes a plurality of panel components (panel components 11, 12, 13, 14, 15, and 16). Here, for the sake of explanation, these panel components are shown in two states at the same time, a pre-assembled state and a post-assembled state. A panel component is a structure that combines a panel and a frame. In this embodiment, the panel components 11, 12, 13, 14, and 15 have a double structure in which a frame is formed on each of an inner surface side and an outer surface side. Two adjacent panel components are fixed to each other by using a bracket (fixing member) in at least one place. Each panel component has a shape combining a rectangular frame and a cross frame. These frames are obtained by fixing pipes or rods to each other with bolts and nuts or by welding.

  Sensor towers 111 and 112 are attached to the panel component 11. Each of the sensor towers 111 and 112 is a member (bar material) to which a plurality of sensor groups are attached. Similarly, panel components 12, 13, 14, and 15 have sensor towers 121 and 122, 131 and 132, 141 and 142, and 151 and 152.

  FIG. 4 is a diagram illustrating the structure of the sensor tower 111. In this example, the sensor tower 111 is provided with five sensor groups 20. The sensor tower 111 is fixed to the panel component 11 at predetermined positions (for example, upper and lower ends). The same applies to sensor towers other than the sensor tower 111.

  Thus, since each panel component is formed by the combination of the panel and the frame, the 3D scanner 1 is lightweight and easy to carry, assemble, and disassemble.

  FIG. 5 is a diagram showing a top view of the frame structure. The top view is a view seen from a position vertically moved upward from the assumed center position C of the subject (viewed from the vertically upward direction). In this example, the top view shows the 3D scanner 1 from a position higher than the 3D scanner 1 on an axis extending vertically upward from the center C (center of the circumscribing rectangle (square) defined by the frame) in the horizontal direction of the imaging room. The shape when looking down. In this example, when viewed from the top, the outer shape of the frame structure of the 3D scanner 1 has a shape in which the circumscribed rectangle having the smallest area is a square. From another point of view, the outer shape of the frame structure of the 3D scanner 1 has a pentagonal shape in which one corner is cut out from a square. In one example, the length of one side of this square is 2.0-2.5 m. The height of the 3D scanner 1 is about 2.0 to 2.5 m. In this example, the gap between the panel component 11 and the panel component 15 corresponds to a notch. A frame 16 is provided between the panel component 11 and the panel component 15. The frame 16 has a rectangular outer shape (smaller than the panel components 11 and 15), and has one end fixed to the panel component 11 and the other end fixed to the panel component 15. The frame 16 is fixed to a position corresponding to only a part of the upper portion of the opening (gap) between the panel component 11 and the panel component 15, and the subject enters and leaves the imaging room of the 3D scanner 1 through this opening. Function as a gateway for

  As for the subject, the direction facing the panel component 13 is assumed to be the front. Since the panel component 13 is in the front direction when entering the photographing room through the entrance, it is rational to position the panel component 13 in the front direction in the positional relationship with the entrance. A monitor 17 is installed on the inner peripheral side of the panel component 13. The monitor 17 is a display device for providing the UI of the 3D scanner 1. A video source (for example, a computer device) that supplies a video signal to the monitor 17 is installed, for example, in the space 139 of the panel component 13 (the computer device is not shown).

  The sensor groups 20 are installed in eight directions when viewed from the center C of the imaging room in a top view. In this example, the arrangement of a plurality of (eight groups in this example) sensor groups 20 is asymmetric before and after the diagonal line X that does not include the panel component 13 (the panel component 13 side is the front and the frame 16 side is the rear). . This is because there is no space (doorway) between the panel component 11 and the panel component 15 so that there is no structure to which the sensor group 20 can be attached. However, the panel group 13 that is symmetrical to the doorway has a sensor group. 20 is installed. Since the panel component 13 corresponds to the front of the subject, it is rational to arrange the sensor group 20 at a position closer to the front. The arrangement of the sensor group 20 is symmetrical with respect to a diagonal line Y (diagonal line of the circumscribing rectangle of the frame) including the panel component 13 and the opening (that is, left and right of the diagonal line X (left and right when the subject faces the front)). .

  The 3D scanner 1 has a frame whose outer edge has a predetermined shape in a top view (including a frame which is integrated with a panel as a panel component). The predetermined shape is, for example, a polygon, more specifically, a rectangular or square pentagon with one corner cut out. The outer edge here can also be called a circumscribed polygon. The circumscribed polygon is one that circumscribes the panel component and has the smallest area. In the example of FIG. 5, the outer edge (= circumscribing polygon) of the panel component is a pentagon, which is a cutout of one corner of the circumscribing rectangle.

  Although only the top view is shown here, one sensor group 20 includes a plurality of sets of image sensors and distance sensors. In one example, each sensor group 20 includes 3-6 sets of image sensors and distance sensors. These plural sets of image sensors and distance sensors are arranged vertically.

  Further, in a top view, the plurality of sensor groups 20 are arranged at a non-equidistant distance from the center C of the photographing room (that is, the ideal position of the subject). In an apparatus for shooting a subject by installing a plurality of sensor groups in a shooting room, it is possible to arrange the sensor groups equidistant from the center of the shooting room or the shooting table. However, when a plurality of sensor groups 20 are arranged at the same distance as that of the sensor group 20 according to the present embodiment, which has the shortest distance from the center C (about 80 cm in one example), the imaging room becomes (in a top view) ) It becomes a circle having a radius similar to the shortest distance, and becomes narrower than the imaging room of the 3D scanner 1 of the present application. Similarly, when a plurality of sensor groups 20 are arranged at the same distance as that of the sensor group 20 according to the present embodiment that has the longest distance from the center C (about 100 cm in one example), the imaging room is In this case, the radius is approximately the same as the longest distance, and the space required for installation becomes large as compared with the imaging room of the 3D scanner 1 of the present application. In general, when the imaging room has a circular shape (when viewed from the top), the entire 3D scanner (when viewed from the top) is often a circular shape or a regular n-gon (n ≧ 5). When the external shape of the device is circular or regular n-sided, the space corresponding to the corner of the circumscribed rectangle is often wasted. On the other hand, the 3D scanner 1 according to the present embodiment has a shape in which a part of a rectangular parallelepiped is cut out as a whole, and a shape in which a part of a square is cut out in a top view. Is excellent. Further, since the frame structure can be simplified as compared with a circular or regular n-sided structure, manufacturing and assembly costs can be reduced.

  In addition, in a 3D scanner, in general, when the position of the camera (sensor) is too close to or far from the subject, the human body (or the one close to the human body), which is the main subject, has a flat (flat) shape. By using the shape of the subject, the sensor group 20 is asymmetrically arranged. Further, in many situations in which a human body is photographed, there is a demand to photograph a face with high image quality. For example, by arranging the sensor group 20 in the panel component 13 at high density, the face can be photographed with high image quality. You can

  Further, the circumscribed ellipse E of the sensor group 20 is flat, and the flatness is greater than 0 (0.2 to 0.3 in one example). It can be said that the monitor 17 is arranged in the vicinity of the short radius of the circumscribed ellipse E.

  Further, a monitor 18 is installed on the outer surface of the 3D scanner 1 (the surface not facing the imaging room). The video source of the monitor 18 is, for example, the same computer device as the video source of the monitor 17. Alternatively, the video source of the monitor 18 may be a device different from the video source of the monitor 17. The monitor 18 is used, for example, to display a waiting time and a caution for a customer (user) before entering the photographing room.

2. Function FIG. 6 is a diagram illustrating a functional configuration according to an embodiment of the 3D scanner 1. The 3D scanner 1 includes a photographing unit 101, a processing unit 102, a model generation unit 103, and a UI providing unit 104. The photographing unit 101 photographs a subject and outputs it as data. The sensor group 20 shown in FIG. 5 and the like is included in the imaging unit 101. The processing unit 102 processes various types of data provided by the image capturing unit 101 and the like. The processing performed by the processing unit 102 includes, for example, detection of a gesture described below. The model generation unit 103 uses the image data output from the sensor group 20 to generate three-dimensional modeling data of the subject. The UI providing unit 104 provides a user interface. The processor and the memory of the computer device (not shown) that functions as the video source of the monitor 17 mentioned in the description of FIG. 5 are examples of the processing unit 102 and the model generation unit 103. The processor and memory, the monitor 17 and the monitor 18 are examples of the UI providing unit 104.

  In this example, the photographing unit 101 starts photographing a subject before receiving an instruction to generate three-dimensional modeling data. Before generating the three-dimensional modeling data, the image capturing unit 101 captures an object for gesture detection. That is, when the shooting unit 101 starts shooting in the shooting room, the subject (user) can give an instruction to the computer apparatus by gesture input. The instruction by the gesture input includes, for example, an instruction to start shooting for generating three-dimensional modeling data, an instruction to display a three-dimensional model using the generated three-dimensional modeling data, and an instruction to end shooting.

3. Operation FIG. 7 is a flowchart illustrating the operation of the 3D scanner 1. More specifically, FIG. 7 is a flowchart illustrating the operation of the computer device installed in the 3D scanner 1. An application program relating to the operation of the present invention is installed in this computer device, and the flow of FIG. 7 is implemented by the processor of the computer device executing this application program. In the following, for simplicity of description, the subject of processing is simply “3D scanner 1”.

  In step S101, the 3D scanner 1 determines whether the subject has entered the photographing room. In one example, the 3D scanner 1 has a motion sensor, and detects that a subject has entered the photographing room based on the output signal of the motion sensor. Alternatively, in the 3D scanner 1, the image capturing unit 101 may always capture an image of the image capturing room while the power is turned on, and by analyzing this image, it may be detected that the subject has entered the image capturing room. When it is detected that the subject has entered the photographing room (S101: YES), the 3D scanner 1 moves the process to step S102. When it is not detected that the subject has entered the shooting room (S101: NO), the 3D scanner 1 waits until the subject enters the shooting room.

  In step S102, the 3D scanner 1 starts photographing a subject for gesture detection. In step S103, the 3D scanner 1 determines whether the subject has made a predetermined gesture. The 3D scanner 1 stores gestures of a plurality of patterns in association with respective instructions. For example, the gesture of "raise your right hand above your head and lower it to the bottom" and the instruction to "start shooting", the gesture "to raise your hands horizontally" and the instruction to "rotate the 3D model", and "left hand to the head". The gesture of "raise up" is associated with the instruction of "end of shooting". When it is determined that the subject has made a predetermined gesture (S103: YES), the 3D scanner 1 moves the process to step S104. When it is determined that the subject does not perform the predetermined gesture (S103: NO), the 3D scanner 1 waits until the subject performs the predetermined gesture.

  In step S104, the 3D scanner 1 performs processing according to the gesture. For example, when “start shooting” is instructed, the 3D scanner 1 starts shooting for generating 3D modeling data. When “Rotate 3D model” is instructed, the 3D scanner 1 displays an image of the 3D model of the subject on the monitor 17 using the generated 3D modeling data, and rotates the 3D model within the screen. When the “imaging end” is instructed, the 3D scanner 1 performs a process for outputting the generated 3D modeling data.

  In step S105, the 3D scanner 1 determines whether the subject has left the photographing room. The method of detecting that the subject has left the shooting room is the same as the method of detecting that the subject has entered the shooting room. When it is detected that the subject has left the photographing room (S105: YES), the 3D scanner 1 moves the process to step S101. When it is not detected that the subject has left the photographing room (S105: NO), the 3D scanner 1 moves the process to step S102.

  According to this example, the imaging unit 101 forms a sensor group for grasping where the point group (positional coordinate) of the subject occupies in the imaging room (3D space). The photography for grasping the pose of the subject in the 3D space by these sensor groups can be used for the gesture input. Since the subject can check his / her own pose on the monitor 17 in almost real time, it is easy to optimize the pose. According to this example, it is possible to easily provide guidance (guidance) for taking an optimal pose.

  Further, according to this example, the space inside the photographing room is widened (the space is effectively used) as compared with an example in which an input device (button or the like) for instruction input is used separately from a computer device for generating 3D modeling data. )be able to. Further, for example, it is conceivable that the monitor 17 is used as a touch screen and an instruction to start shooting is input through the touch screen. However, compared to such a configuration, the subject moves from an ideal position (center C). It has the advantage that instructions can be entered without doing so. Moreover, since the 3D scanner 1 acquires the surface shape and color information of the subject in the photographing room with high spatial resolution, it is possible to take a highly precise pose.

  Further, according to this example, it is possible to generate a 3D model using so-called AR (Augmented Reality) technology. Specifically, the subject can be made to have a virtual 3D object (balloon as an example). Also in this case, the 3D object can be exchanged with another object, the position and the size can be corrected, and various adjustments can be made in almost real time.

4. Operation Example FIG. 8 is a diagram illustrating a service menu displayed on the monitor 18. Hereinafter, a more specific operation example of the 3D scanner 1 will be described. For example, the menu of FIG. 8 is displayed on the monitor 18. In this example, it is shown that the stationary model is generated for 500 yen and the movable model is generated for 1000 yen. The stationary model refers to a model with a fixed pose, and the movable model refers to a model in which some joints can be moved and different poses can be taken. The monitor 18 is a touch screen, and when the user touches a portion where a desired item is displayed, the 3D scanner 1 is instructed to execute the item. When the menu is selected, the user enters the shooting room through the doorway.

  FIG. 9 is a diagram illustrating a screen displayed on the monitor 17. When the user selects a menu item via the monitor 18, a screen corresponding to the selected menu item is displayed on the monitor 17. In this example, the explanation "Please stand up to the mark on the floor. When you're ready, raise your right hand above your head and lower it down. The picture will be taken in 3 seconds." To be done. At this time, the 3D scanner 1 is in the state of waiting for the gesture input in step S103. The user looks at the mark on the floor to check his or her standing position, and when ready, raises his right hand above his head and then lowers it. When this gesture is detected, the 3D scanner 1 starts the countdown of shooting. On the monitor 17, the count until shooting (shutter) is displayed. That is, this gesture is an example of a gesture that specifies the shooting timing. When photographing is performed, the 3D scanner 1 processes the image data and the distance data output from the sensor group 20 with a predetermined algorithm to generate 3D modeling data of the subject.

  FIG. 10 is a diagram illustrating a screen displayed on the monitor 17 after the generation of 3D modeling data. Here, the image of the 3D model formed according to the generated 3D modeling data is displayed (preview display). In addition, the explanation "The model rotates when you raise both hands horizontally. If this model is good, please raise your right hand above your head. If you want to start over, please raise your left hand above your head." To be done. For example, when the user raises both hands horizontally here, the 3D model displayed on the monitor 17 rotates (that is, the viewpoint of the 3D model is changed). In another example, when the movable model is generated in the 3D scanner 1, the pose of the movable model may change in association with the gesture of the user. For example, when the user raises the right hand, the 3D model also raises the right hand within the screen of the monitor 17. Through the display of the 3D model (which may include changing the viewpoint and changing the pose), the user can confirm on the spot whether the requested 3D model has been generated.

  When the shooting is completed, the process proceeds to transfer the generated 3D modeling data. In one example, the passing of 3D modeling data is done via the monitor 18. Specifically, for example, the 3D scanner 1 uploads the generated 3D modeling data to a predetermined server on the Internet. The 3D scanner 1 displays on the monitor 18 information for downloading this 3D modeling data. The information for downloading the 3D modeling data includes, for example, at least one of a URL for downloading, an IDS for accessing the server, and a password. These pieces of information may be displayed as characters or may be coded and displayed as an image (for example, a QR code (registered trademark)).

  Alternatively, the 3D scanner 1 has a writing device (not shown) for writing data in a storage medium (CD-ROM, USB memory, etc.), and the storage medium in which the 3D modeling data is written is written via the writing device. The 3D modeling data may be provided to the user by outputting.

5. Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made. Hereinafter, some modified examples will be described. Two or more of the following modifications may be used in combination.

  The frame structure of the 3D scanner 1 is not limited to the one exemplified in the embodiment. For example, the doorway may be formed not at a position corresponding to a corner of a circumscribing rectangle having the smallest area in a top view but at a position corresponding to a side. However, considering that a human being is a subject (a human being is wide laterally), it is better to use the space at a position corresponding to the corner of the circumscribing rectangle having the smallest area as in the example of FIGS. .

  FIG. 11 is a diagram illustrating a frame structure of the 3D scanner 1 according to the modification. Although the example in which the 3D scanner 1 has only one entrance / exit has been described in the embodiment, in this modification, the 3D scanner 1 has an entrance and an exit different from this entrance. Further, in this example, the inlet and the outlet are provided on the diagonal line of the circumscribed rectangle. The subject can enter the shooting room from the entrance, shoot, and then exit the exit without changing direction (walk-through format). For example, if this 3D scanner 1 is installed at the entrance of a store, the 3D scanner 1 can generate a 3D model of a customer when entering the store, and the customer can enter the store as it is. In this case, the monitor 17 and the sensor group 20 cannot be installed because the front of the subject is the exit. However, for example, in the panel components 12 and 14, many sensor groups 20 are arranged at positions close to the subject's face, or the height of the panel component in front of the subject is made higher than the human body, and a margin is provided above the exit, You may install the monitor 17 or the sensor group 20 in this margin part.

  In this example, the outer edge of the 3D scanner 1 has a shape (a hexagon as a whole) in which two opposite corners are cut out in a circumscribed square having the smallest area. Of these two notches, one corner (lower left corner) is the entrance and the other corner (upper right corner) is the exit.

  Further, the frame of the 3D scanner 1 may not have the double structure as exemplified in the embodiment. However, considering the structural strength and stability of the 3D scanner 1 after installation and the ease of processing the interior and exterior, it is preferable to make the frame a double structure as in the examples of FIGS. Further, the 3D scanner 1 may have a structure in which, for example, a box-shaped member is combined to form a wall instead of a structure in which an external or internal plate member is attached to a frame in which pipes or rods are combined.

  Further, the panel component of the 3D scanner 1 is not limited to the planar shape (plate shape) exemplified in the embodiment. For example, each panel component may have a profile shape, and the 3D scanner 1 may be, for example, an oval or ellipsoid as a whole.

  Further, the 3D scanner 1 is not limited to the booth type as exemplified in the embodiment. The 3D scanner 1 may have a configuration in which the sensor tower is directly placed on the floor surface without the panel component. In this case, the sensor tower has a structure such as a pedestal that can stand on its own.

  The mounting position of the sensor group 20 is not limited to the one exemplified in the embodiment. In the embodiment, five sensor groups 20 are attached to one sensor tower, and the attachment positions of these five sensor groups 20 are common to all the sensor towers (that is, in each sensor tower, from the bottom n The positions of the second sensor group 20 are all the same). However, the position of the nth sensor group 20 from the bottom in each sensor tower may be different from the position of the sensor group 20 in another sensor tower.

  The functional configuration and hardware configuration of the 3D scanner 1 are not limited to those exemplified in the embodiment. Some of the functions illustrated in the embodiments may be omitted, or hardware different from those illustrated in the embodiments may be used. For example, different computer devices may be used for detecting the gesture and generating the 3D modeling data, respectively.

  The method of inputting an instruction to the 3D scanner 1 is not limited to gesture input. For example, a method other than the gesture input such as voice input may be used.

  The subject of the 3D scanner 1 is not limited to the human body (human). For example, the subject may be clothes. In this case, the computer device of the 3D scanner 1 may measure the size of the clothes in addition to (or instead of) generating the 3D model of the clothes. The size of the clothes is represented by a set of predefined lengths such as neck, chest, waist, sleeve length, and dress length.
