  The scanner 32 for acquiring image data scans a plan of a building, which is mainly a paper medium, but may be a photograph of a floor surface on which a panel is to be applied besides the plan. The photograph on the floor may be a so-called print printed on a printing paper, or a film on which a negative or positive image is recorded, as long as the scanner 32 can scan a transmission image. In the present embodiment, a paper medium such as a design drawing, a film on which an image is recorded, and a printing paper are collectively referred to as a fixed medium. In addition, instead of the scanner 32, a fixed medium such as a design drawing may be photographed using a digital camera, a smartphone, or a tablet terminal to acquire image data.

  The network 70 is, for example, the Internet, and the work terminal 30 communicates with the member maker 72 and the contractor 74 by https (Hypertext Transfer Protocol Secure), which secures confidentiality by encrypting information related to communication. Alternatively, by performing encrypted communication between the work terminal 30 and the member maker 72 and the contractor 74, a VPN (Virtual Private Network) for constructing a virtual dedicated line may be used.

  FIG. 2 is a block diagram showing a schematic configuration of the work terminal 30 in the floor finish automatic allocation system 10 according to the present embodiment. The work terminal 30 includes a central processing unit (CPU) 12, a hard disk drive (HDD) 14, a random access memory (RAM) 16, a network I / F unit 18, and a read only memory (ROM) 20. Including. The work terminal 30 includes a display unit 22, an operation input unit 24, and a bus 26, and has functions of a terminal for inputting information and a terminal for displaying information.

  The CPU 12 manages the entire operation of the work terminal 30, and also controls the display unit 22 and the operation input unit 24. The HDD 14 is a non-volatile storage device in which a floor finish automatic allocation program, a communication program with the member maker 72 and the contractor 74, an OS (Operating System), data used for executing each program, and the like are recorded. The RAM 16 is a volatile storage device in which an OS, a program or data is deployed. The floor covering automatic assignment program and the communication program with the component maker 72 and the contractor 74 may be independent programs or integrated programs. Note that the communication program with member manufacturer 72 and contractor 74 is added to floor finish automatic assignment program in the form of an add-on or plug-in of floor finish automatic assignment program, and a program that cooperates with floor finish automatic assignment program It may be

  The network I / F unit 18 is for connecting to the network 70, and is configured of an NIC (Network Interface Card) and its driver. The ROM 20 is a non-volatile storage device in which a boot program or the like that operates when the work terminal 30 starts up is stored. The display unit 22 displays information on the design to the user. The operation input unit 24 is used when the user inputs an operation or information of the floor finishing automatic allocation system 10, and as an example, an input device such as a touch panel or a keyboard and pointing such as a trackball, a pen tablet or a mouse Device is included. The bus 26 is used when exchanging information.

  The external interface 28 is an interface for connecting a scanner 32 or the like that acquires image data, and as one example, conforms to any standard such as USB (Universal Serial Bus), IEEE 1394, Thunderbolt, or SCSI.

  FIG. 3 is a flow chart showing an example of the process of the floor finish automatic allocation system 10 according to the present embodiment.

  In step 300, a paper medium such as a plan of a building is read by the scanner 32 to acquire image data of the floor of the building. FIG. 4 is an example of image data of a floor of a building acquired by the scanner 32. When a plan of a building does not remain, image data may be acquired from a picture of the floor of the building. FIG. 5 is a schematic view showing an example of imaging of a floor of a building. In FIG. 5, the floor surface 40 of the building is photographed by a camera 42 attached to the stand 44. The stand 44 holds the camera 42 so that the optical axis of the lens of the camera 42 is perpendicular to the center of the floor surface 40. The camera 42 is not limited by the type of photographic medium (silver-salt film or image sensor) and the size (format) of the photographic medium, but it is desirable that the camera 42 has an elevation mechanism capable of correcting image distortion if possible.

  The stand 44 preferably has a counter weight 44A for securing a weight balance with the camera 42 in order to stably hold the camera 42 having a corresponding weight.

  In addition, since a part of the stand 44 inevitably appears in the image taken as shown in FIG. 5, the image is corrected by bitmap image editing software or the like as needed.

  In step 302, it is determined whether a scale has been set on the acquired image data. FIG. 6 is a schematic diagram showing an example when a scale is set to image data. The setting of the scale is, for example, measuring the distance between DL (Datum Line) of the opposite end face in the unit and setting it on the image data. In FIG. 6, the distance between the left and right DLs of the lower left room is set to 2500 mm. In this embodiment, when a point corresponding to one DL is clicked by a pointing device such as a mouse, a perpendicular to the one DL at the one point is drawn on the image data displayed on the display unit 22. The user sets the scale by setting the reference line of scale setting by clicking the intersection of the DL opposite to one DL and the perpendicular with the mouse or the like, and then inputting the actual measurement value of the reference area. In the present embodiment, it is desirable that the coordinate designation of the end point of the reference line be performed accurately in pixel units, so the image data displayed on the display unit 22 can be enlarged as necessary to enable precise coordinate designation. Let's do it. Alternatively, a portion where the numerical value (pixel value) of the pixel on the image data changes greatly is extracted as DL, and when there is a problem with the accuracy of the user's operation with a mouse etc., it exists near the point specified by the user. Points at which the pixel values greatly change may be used as the start point and the end point of the reference line.

  In step 304, based on the scale setting, the actual size of the building indicated by the image data is calculated. In step 304, the relationship between the number of pixels in the image data and the actual size of the building is extracted by correlating the actual size designated in the scale setting with the number of pixels between the opposing DLs which are reference lines for the scale setting. Based on the relationship, the actual dimensions of the floor surface corresponding to the image data are calculated.

  In step 306, it is determined whether a target area for panel allocation has been selected. FIG. 7 is a schematic diagram showing an example in which a target area of panel allocation is set in image data. For example, as shown in FIG. 7, the target area 60 for panel allocation is set by performing coordinate specification in which each corner of the floor surface is clicked with a mouse or the like. In the present embodiment, since it is desirable to perform coordinate specification accurately in pixel units, the image data displayed on the display unit 22 is enlarged as necessary to enable precise coordinate specification. Alternatively, a point where the numerical value (pixel value) of the pixel on the image data changes greatly is extracted as a corner of the floor, and when there is a problem with the accuracy of the user's operation with the mouse, the vicinity of the point specified by the user The point at which the pixel value present in the image changes greatly may be designated as coordinates.

  In step 308, it is determined whether a member has been selected. The selection of members is selected from a member selection table displayed in a window separate from the display of the image data on the display unit 22. FIG. 8 is a schematic view showing an example of a member selection table in the present embodiment. As shown in FIG. 8, in the member selection table, the width, length, offset dimension and form of each member are described, and the user clicks a row relating to any member with a mouse etc. select. In addition, as shown in the term of "the form" of FIG. 8, the shift dimension has shown the shift | offset | difference of arrangement | positioning in the longitudinal direction of the upper stage in a member, and a lower stage.

  In step 310, it is determined whether the selection of the placement point has been made. The placement point is a position at which panel assignment starts. Generally, approximately the center of the floor surface, a corner of the floor surface, or a point on a side of the floor surface is designated. FIG. 9 is a schematic diagram showing an example of placement point designation in the present embodiment. The user moves the cursor 50 such as a mouse to a position where the arrangement point is to be specified, and specifies the arrangement point by clicking.

  In the case of a positive determination in step 310, panel allocation and the required number of panels are calculated in step 312. FIG. 10 is a schematic diagram showing an example of panel allocation in the present embodiment. As shown in FIG. 10, a state in which the panel is allocated to the target area for panel allocation is displayed, and the number of panels necessary for allocation is specifically displayed in another window.

  The layout of the panels is performed based on the shape of the target area, the actual dimensions and the dimensions of the panels. On the target area 60 extracted as shown in FIG. 7, the area of one panel whose size on the target area 60 is adjusted based on the relationship between the number of pixels of the image data and the actual size of the building described above Divide into each panel and assign panels.

  In the present embodiment, the longitudinal direction of the target area is detected from the distribution of the pixels in the target area, and a straight line parallel to the longitudinal direction passing through the arrangement point is set as the arrangement line. Then, the area for the first panel is set with the arrangement point coincident with the apex of the area for one panel, and with the long side of the area for the panel overlapping the arrangement line, Thereafter, the target area is divided into areas of one panel so as to be adjacent to the area and not to overlap each other.

  In many cases, at the border of the target area, the area of one panel is partially displayed as if it was cut at the border. In this embodiment, as a result of dividing the target area into the area of one panel, interference with the boundary of the target area causes the shape and number of pixels of the area of the panel in which a part remains in the target area. Calculate the shape and size of each of the panels in contact with the

  In the case of a negative determination in step 310, panels are allocated with the arrangement point default value in step 314, and the required number of panels is calculated. The default arrangement point is, for example, approximately the center of the floor surface. Alternatively, when the panels are allocated with the approximate center of the floor surface, the corner of the floor surface, or one point on the floor surface as the arrangement point, the display unit 22 displays the case where the required number of panels is minimum. May be

  At step 316, the calculation result of the type of member, the allocation of panels, and the required number of panels is transmitted to the member maker 72 and the contractor 74, and the process is ended. The member maker 72 prepares and ships the required number of members of the designated type and the construction company 74 installs the panels according to the calculated panel allocation.

  As described above, according to the present embodiment, an image recorded in a design of a building or the like recorded on a fixed medium such as a paper medium is extracted as image data. Further, in the present embodiment, the relationship between the number of pixels of the extracted image data and the actual size of the floor of the building is determined by comparing the number of pixels between any two points on the image data and the floor corresponding to the two points. The actual dimensions of each part of the floor surface can be calculated from the image data by correlating the actual dimensions between the two points.

  Furthermore, in the present embodiment, panels are allocated in the target area based on the calculated actual dimensions of the floor surface and the dimensions of the panels, and the number of panels required for the allocation is calculated. Automatic assignment of panels is possible even when there is no data.
