Reflected.

  That is, the functions of these modules 5a to 5d are combined to realize the image processing means and the GUI function in the reform support system of the present embodiment.

  Next, the operation of the system of this embodiment will be described based on the flowchart of FIG. 2 and the screen displayed on the display 1a.

  FIG. 3 shows an initial screen displayed on the display 1a immediately after the system is started by executing the software installed in the computer apparatus 4. The initial screen includes a title bar 10, a toolbar 20, an operation guide. 30, a work area 40 and an operation panel 50 are displayed.

  Three buttons 11 to 13 arranged at the right end of the title bar 10 are buttons for screen operation, and are a minimize button 11, a maximize button 12, and an end button 13 from the left.

  The toolbar 20 is provided with an image reading button 21, an initial setting button 22, an area button 23, a mask button 24, a paste (pasting) button 25, a shadow button 26, a save button 27, a print button 28, and a scale button 29. These buttons 21 to 29 function as effective buttons according to the progress of work.

  Here, the image reading button 21 is a button for reading image data in which a building to be processed is imaged. When the button is clicked with the mouse 2a which is one of the input devices 2, the building image data is stored. The screen for opening the file is displayed, and the image data of the building to be renovated is taken or read by specifying the location of the image file, the image file name, and the file type, and opening the file. Are displayed in the work area 40. In the system of the embodiment, the image data stored in the storage device 3 is selected in advance, but it is attached to each from a digital camera or a memory card read / write device connected via the input / output interface 4c. It is also possible to select image data in a memory card. The image data may be a picture of a house taken with a silver salt film and digitized with a scanner.

  The initial setting button 22 is effective after the image data is read, and is a switching button for performing initial setting of specifications when an operation for image replacement is performed. The region button 23 is a switch button to the region creation step S10 (see FIG. 2) for designating a range to be changed. The mask button 24 is a switch button to the mask creation step S11 (see FIG. 2) for designating a range that is not desired to be changed in the designated area.

  The pasting (pasting) button 25 is a switching button to the image pasting step S12 in which the image data of the material or the member is arranged in the designated area. The shadow button 26 is a switch button to the shadow effect adding step S13 (see FIG. 2) for adjusting the brightness and shadow of the pasted material. The save button 27 is a button operated when saving the work state in a predetermined format. When the file (V) on the menu bar is clicked, an operation called “export” can be performed. In this “export”, only the edited image can be saved in the JPEG or BMP format.

  The print button 28 is an operation button for printing the image at that time displayed in the work area 40 by the printer 1b which is one of the output devices 1, and the scale button 29 is an image displayed in the work area 40. It is an operation button used when measuring the dimension on 42.

  A display magnification setting column 201 is provided at the right end of the toolbar 20, and the display magnification of an image displayed in the work area 40 can be changed in the display magnification setting column 201.

  The operation guide 30 displays, in a simple sentence, an explanation for guiding the user what to do in the current step, and the contents of the explanatory sentence are sequentially switched and displayed as the step proceeds.

  The work area 40 is an area where a building image 41 (see FIG. 4A) is displayed. After the area creation and mask creation steps, the image is edited in the image pasting step S12, the shadow adding step S13, and the like. It is an area where the state of being applied is displayed.

  The operation panel 50 displays an operation procedure in a visually easy-to-understand manner so that even a user who is a beginner can easily operate it, and only the operation buttons necessary for the current step appear. In the initial screen of FIG. 3, an image reading button 210 is displayed. That is, this initial screen is a screen corresponding to the image reading step S1 in FIG. 2. In this initial screen, the image reading button 210 is displayed on the operation panel 50, and the “image reading button is clicked to call the image. The explanation “Please” is only displayed on the image reading button 210, and the initial setting guide screen 52 (see FIG. 4A) is not displayed.

  The function of the image reading button 210 is exactly the same as the function of the image reading button 21 on the toolbar 20, and the user can read an image by operating either button. It should be noted that the image reading button 210 does not appear on the operation panel 50 in the steps after the area creation step S10 described later, and therefore, if it is desired to edit another image at this stage, the image reading button 21 on the toolbar 20 is used. It will be.

  When the image reading button 21 or 210 is used to read image data obtained by color-imaging the building to be processed with a digital camera or the like, or image data consisting of a drawing created by a CAD device, the work area 40 is displayed in FIG. ), An image 41 obtained by photographing the building is displayed. The displayed image 41 is actually displayed in color.

  When the image 41 is read, the initial setting button 22 of the tool bar 20 is enabled, and the operation guide 30 displays a guide sentence for creating a reference plane. The processing step on the initial setting screen corresponds to the three-dimensional information input step S2 in FIG.

  On the operation panel 50 of the initial setting screen, first, the type of the building display form displayed in the image 41 shows the appearance (the appearance with the outer corner (corner) in the center) or the inside. Selection buttons 221 to 222 for selecting whether the object or the front is displayed, and a guidance screen 52 are displayed. The initial setting screen immediately after starting is in a state in which the selection button 221 corresponding to the type of appearance state is operated, and the initial setting guide screen 52 displayed below the selection buttons 221 to 223 includes A picture showing the exterior of the building (housing) seen from the corner is displayed, and the text “Add the direction of the reference by clicking on the corner of the building in the order of 1, 2, and 3 in the figure below” is added. Is done.

  Here, when the type of the display form of the building displayed in the image 41 is internal (interior), the selection button 222 may be clicked with the mouse 2a. In this case, the operation panel 50 as shown in FIG. The guide screen 52 displays a picture in a state where a corner (corner) inside the building is viewed. Furthermore, when the display state of the building displayed in the image 41 is front (for example, image data corresponding to a front view generated by a CAD device or image data captured from the front), the selection button 223 is clicked with the mouse 2a. In this case, as shown in FIG. 4C, a picture of the building as viewed from the front is displayed on the guide screen 52 of the operation panel 50. In the case of this front, the text “Add the direction of the reference by clicking on the corner of the building in the order of 1 to 4 in the figure below” is added.

  The operation guide 30 on the initial screen displays an explanatory note “Let's create a wire surface by specifying three points in the order of the numbers on the operation panel”. It can be easily understood that the corner of the building in the image 41 displayed in the work area 40 should be clicked with the mouse 2a in the order of → 3 (or number 1 → 2 → 3 → 4). When the selection operation of the display state type is completed, the user performs an operation of designating and inputting a point on the image 41 corresponding to the above numbers 1 to 3 or 1 to 4 using the mouse 2a. The point that is specified and input becomes the reference point for creating the reference plane.

  Next, the operation for inputting the reference point will be described with reference to FIG. FIG. 5 is a diagram in which the image 41 in FIG. 4A is replaced with a line drawing for easy understanding, and shows a case where the appearance is selected as the type of display form.

  First, in order to designate and input the reference point corresponding to the number 1, when the mouse 2a is placed on the upper end of the vertical line where the left side surface and the right side surface of the building intersect, and the mouse 2a is left-clicked, FIG. As shown in a), under the control of the modules 5a to 5d of the CPU unit 4, the origin O is displayed at the position where the mouse cursor has been placed, and a line segment of a certain length hanging from the origin O is displayed. OH is automatically displayed by the drawing control module 5d.

  By the way, when analyzing the photograph of the building, the upper end of the vertical line where the left side and the right side of the building intersect generally appears in many cases. Something is placed, planted, or the car is parked, so it may not be visible. Even if it sees Fig.5 (a), although the upper end of the perpendicular line where the left side surface and right side surface of a building cross | intersect is visible, the lower end is not visible.

  In consideration of the characteristics peculiar to the photograph which photographed such a building, in this system, as the 1st point (origin O) for 3D information input, the vertical where the left side and the right side of the building intersect I am going to get the top of the line. Further, the length of the line segment OH hanging from the origin O can be adjusted later.

  Here, the line segment OH in FIG. 5A completely overlaps the vertical line where the left side and the right side of the building intersect, but this is because the lower end H is input as the second point. If the origin O is determined as described above, the lower end H is automatically displayed. The reason why this automatically displayed line segment OH conveniently overlaps the vertical line where the left side and the right side of the building intersect will be explained. This is because most people shoot such that the vertical line where the left side surface and the right side surface intersect is the vertical direction on the image. If you read an image in which the vertical line that intersects the left and right sides of the building is not vertical on the image (the building itself is tilted), drag the wire frame as described below. Can be moved and adjusted. Further, it can be dealt with by adjusting the orientation of the image by using the image rotation function and the inclination correction function and by finely adjusting the wire frame.

  In this way, where the line segment OH is automatically drawn so that a perpendicular line of an appropriate length descends from the input first point (origin O), the building has many vertical lines, When taking a picture, it is used to determine the length and breadth along the vertical line.

  Next, input of the second point will be described. When the input of the first point (origin O) is completed and the mouse button is released, the image of FIG. 5B is displayed, and the second line different from the first line segment OH extending from the origin O is displayed. A second point (left end L) is displayed on the minute. This second point (left end L) is interlocked with the mouse cursor, and when the mouse 2a is moved, a quadrangle having two adjacent sides of line segment OL and line segment OH is shown in FIG. → FIG. 5 (c) → Deformation as shown in FIG. 5 (d). As shown in FIG.5 (d), after adjusting so that the upper side of the left side of a building and line segment OL may correspond, when the mouse 2a is left-clicked, the 2nd point (left end L) is input. Is completed. Note that a quadrangle having two adjacent sides of the line segment OL and the line segment OH is a vertical line that divides the line segment OL into five equal parts and a diagonal line that divides the line segment OH into five equal parts. A grid line (grid) is formed, and a quadrangle including the grid line is referred to as a reference plane made of a wire frame. The number of grid lines constituting the wire frame of the reference plane is not limited in the embodiment, but the number is such that plane information can be grasped.

  Next, input of the third point will be described. When the input of the second point (left end L) is completed and the mouse button is released, the image of FIG. 5E is displayed, and the first line segment OH and the second line segment O- extending from the origin O are displayed. A third point (right end R) is displayed on a third line segment different from L. This third point (right end R) is interlocked with the mouse cursor, and when the mouse 2a is moved, a quadrangle having a line segment OR and line segment OH adjacent to each other is shown in FIG. → FIG. 6 (f) → Deformation as shown in FIG. 6 (g). As shown in FIG. 6 (g), after adjusting so that the upper side of the right side of the building coincides with the line segment OR, when the mouse 2a is left-clicked, the third point (right end R) is input. Is completed. In addition, the quadrangle having the line segment O-R and the line segment OH adjacent to each other has a vertical line that divides the line segment O-R into five equal parts and a diagonal line that divides the line segment OH into five equal parts. Constitutes a grid line. A quadrangle including the grid lines is set as a second reference plane. Further, when the reference plane shown in FIGS. 5B to 5D is the first reference plane, the first and second reference planes are hinged with the line segment OH as the pivot. It can be seen that a solid figure that can be deformed is shown. The first surface (first reference surface) of the three-dimensional figure is attached to the left side surface of the building as shown in FIG. 5 (d), and the second surface (second reference surface) is shown in FIG. 6 (g). Line segment O where the first and second reference planes intersect with the vertical line where the left side and right side of the building intersect as shown in FIG. 5 (a). By matching -H, the present system can acquire the three-dimensional information copied in the read two-dimensional image data.

  By the way, in the system of the present embodiment, when the appearance is selected by selecting the type of display mode described above, the length of the line segment OH corresponding to the first point as shown in FIG. By setting the lengths of the vertical line segment LL ′ on the left side of the first reference plane and the vertical line segment RR ′ on the right side of the second reference plane to be short, A reference plane with a sense of perspective is automatically drawn. When the interior (interior) is selected, the first point is designated and input to the upper end of the interior corner of the room. The vertical line segment O displayed when the first point is designated and input is displayed. With respect to −H, the vertical line segment LL ′ corresponding to the second point and the third point designated and input with respect to the upper end of one side of both sides and the right side of the second reference plane By setting the length of the side line segment RR ′ to be long as shown in FIG. 7B, a reference plane having a perspective as viewed from the photographing point is automatically drawn. That is, by providing a variable according to the type of display form of the building displayed in the image 41 and referring to the variable according to the type of display form selected, the designated input positions of the second point and the third point Whether to create a reference plane located in the depth direction of the screen or a reference plane located in the forward direction with respect to the position of the first point is determined.

  When the type of display form is a plane (such as a plan view created by a CAD device), a vertical line segment corresponding to the first point, that is, the origin O, as shown in FIG. The length is set by the position L ″ of the fourth point, and the length of the vertical line segment corresponding to the second point (R) is set by the position (R ″) of the third point. .

  In the image showing the interior (interior) as shown in FIG. 7D, when there are three or more wall surfaces, the vertical length of the side of the wall surface corresponding to the position of the second point is shown. Since the length is shorter than the length in the vertical direction of the side edge of the wall surface located at the first point, it can be dealt with in the fine adjustment surface editing step S3 to be described later after the reference surface is created.

  When the input of the first point to the third point is completed as described above, the display of the operation guide 30 and the operation panel 50 is switched as shown in FIG. As shown in FIG. 8, the initial setting guide screen 52 disappears on the operation panel 50 and a reference screen fine adjustment setting screen 53 is displayed.

  Further, the operation guide 30 displays “Let's finely adjust the created wire surface and input the dimension between light blue arrows.”

  Here, the light blue arrow is displayed corresponding to the “left side width”, “right side width”, and “height” selected on the operation screen 54, for example, “left side width”. 6 is displayed in correspondence with the line segment OL in FIG. 6G, and if the “right side width” is selected on the operation screen 54, the image of the work area 40 is shown in FIG. 6 (h), and the arrow between the line segments OR is displayed in light blue. Similarly, if “height” is selected on the operation screen 54, the image of the work area 40 is shown in FIG. 6 (i). It switches as follows. In this way, after selecting one of them, the measured dimension of the selected object may be input as a numerical value.

  If the input of the first point (origin O), the second point (left end L), and the third point (right end R) is an input of three-dimensional angle information, line segments OR, OL, The input of the length of OH is input of three-dimensional dimension information, and in this system, the three-dimensional angle information and dimension information imprinted in the read two-dimensional image data are acquired. It can be done. Although the input of dimensions can be omitted, in order to calculate the estimate by automatically calculating the pasting area of the exterior material, or to automatically calculate the tiling pitch and scaling factor of the object to be pasted, the dimension must be selected. It is better to enter.

  In some cases, the 3D information input step can be completed, but was the focal length setting when shooting with the digital camera set to the telephoto side or wide angle side from the standard, or was the shooting position looking up at the building? Depending on whether the position is looking down, fine adjustment of the reference surface may be necessary. Therefore, the angle of the lower side of each reference plane is adjusted to the angle of the left and right sides of the building as shown in FIG. In addition, when the lower side of the building is hidden behind a shadow and cannot be seen well, a member including information parallel to the lower side of the building, such as a window frame or a door frame, and a plurality of grid lines of the wire frame constituting the reference plane Just set the direction.

  FIG. 9 is an explanatory diagram for explaining the functions of the three slide bars 53a to 53c provided on the installation screen 53 (see FIG. 8) for fine adjustment of the wall surface. For example, with respect to the reference plane shown in FIG. 9C, the lower sides L′-H and R′-H of both the left and right reference planes are lengthened as shown in FIG. 9A and looked down from above. Sometimes, the center slide bar 53b is operated downward. On the contrary, the lower sides L′-H and R′-H of the left and right reference planes are shortened as shown in FIG. 9B with respect to the reference plane shown in FIG. If desired, the center slide bar 53b is operated upward.

  Further, when it is desired to reduce the angle between the vertical line OH and the lower side L′-H of the left reference plane with respect to the reference plane shown in FIG. 9C, as shown in FIG. The slide bar 53a is operated upward. Conversely, when it is desired to return from the state of FIG. 9D to the state of FIG. 9C, the slide bar 53a is operated downward.

  Furthermore, when it is desired to reduce the angle between the vertical line OH and the lower side R′-H of the right reference plane with respect to the reference plane shown in FIG. 9C, as shown in FIG. The right slide bar 53c is operated upward. Conversely, when it is desired to return from the state of FIG. 9E to the state of FIG. 9C, the slide bar 53c is operated downward.

  Thereby, the angle of the lower side of each reference plane is accurately adjusted to the angle of the left side surface and the right side surface of the building from the state of FIG. 6 (i) as shown in FIG. 6 (j).

  In addition, the vertical and horizontal grid lines are dragged with the mouse 2a and moved on the reference plane in correspondence with the window position and wall position of the wall of the building that overlaps the reference plane. By dropping at a position that matches the boundary line, it is possible to display a reference plane in which the user can intuitively understand the deviation between the building and the reference plane. In addition, operations such as area creation, mask creation, material pasting, and part placement, which are performed later, can be easily performed along the angle and part of the building. Furthermore, in this embodiment, a grid line can be added on the reference plane by operating the mouse 2a.

  In the example of FIGS. 8 and 9, the left slide bar 53a and the right slide bar 53c can be operated separately with emphasis placed on easy understanding of the operation. However, as described above, this operation is digital. Supports fine adjustment when the focal length setting when shooting with the camera is shifted to the telephoto side or wide angle side from the standard, so if either one is combined, the other can be automatically linked and adjusted. It doesn't matter if you do.

  The principle will be described with reference to FIG. The solid lines in the figure represent the left and right sides of the building as an origin O, a lower end H, a left upper end L, an upper right end R, a left lower end L ', and a right lower end R'. The elongated dotted line is a straight line obtained by extending line segments OL, OR, H-L ', and H-R' toward the infinity point. The point where the extension lines of the line segments OL and H-L ′ intersect exists on the horizon indicated by the thick dotted line. Moreover, the point where each extension line of line segment O-R and H-R 'crosses also exists on the horizon. Accordingly, when the angle formed by the line segment HL ′ and the line segment OH is determined, the height of the horizon line on the image is determined. Therefore, the line segment HR ′ and the line segment OH are formed. The angle is also uniquely determined. Therefore, instead of the slide bars 53a and 53c in FIG. 8, a slide bar 53d for viewing angle adjustment as shown in FIG. 10B is provided, and the focal length at the time of shooting of the digital camera is set to the telephoto side from the standard or It may be adjusted only to shift to the wide angle side.

  In the above description, it is preferable to carry out the dimension input and the fine adjustment of the reference plane (wall surface), but the fine adjustment of the reference plane is not necessarily required depending on the image of the building. The dimension input may be omitted. Further, it is preferable that the angle between the lower side of the reference surface and the line segment is initially set in advance so that the fine adjustment of the reference surface (wall surface) can be almost omitted under standard imaging conditions.

  In the process of creating the reference plane as described above, when it is desired to input the three-dimensional information from the beginning, if the reset button 56 provided below the operation panel 50 in FIG. 8 is operated, FIG. You can return to the state.

  By the way, in the display type image corresponding to the appearance and the interior (interior) as described above, two adjacent reference planes are automatically created by designating and inputting three reference points. As shown in FIG. 11, in the case of a building having three or more wall surfaces, the reference plane surface editing (addition) step S3 is added to the three-dimensional information input step S2 so that the reference plane can be added. Next to FIG. 2, it is provided.

  In this surface editing step S3, for example, an angle input is performed regarding the positional relationship with respect to the adjacent reference surface, and when this angle is input, the drawing control module displays the provisional position of the additional reference surface X on the image 41. And a step S4 of a reference surface addition process including a step of adjusting the provisional position of the additional reference surface X in the screen by dragging with the mouse 2a on the screen or a slide bar for displaying the angle on the operation panel 50. In the case of four or more surfaces, the above-described steps are repeated so that additional reference surfaces X can be sequentially created.

  When the creation of the desired reference plane is completed as described above, the input of the three-dimensional information is completed as shown in FIG. 6 (j) of the step switching process 1 as shown in FIG. When the user wants to move, the user moves to the state shown in FIG. 12 by operating the “Next” button 57 provided below the operation panel 50 in FIG. 4A or the region button 22 on the toolbar 20.

  Basically, it is possible to move to the next step by operating the “Next” button 57 on the operation panel 50, so the button on the toolbar 20 is operated when moving forward only. Although it is not necessary, when you want to return to the previous step, it is devised so that you can return to any step by using the button on the toolbar 20 instead of returning one step at a time using the “Return” button. is there. In addition, since any one of the buttons 21 to 28 on the toolbar 20 is highlighted (displayed in a different color or displayed in a depressed state, preferably both), which step is the current step. It also has a function to display what it is.

  Now, a case where the above-described button 57 or area button 22 is operated and the process proceeds to area creation step S10 will be described.

  FIG. 12 shows a screen in the initial state of the region creation step S10, and the region button 22 on the toolbar 20 is displayed in a color different from other buttons. The operation guide 30 is instructed to “select buttons on the operation panel and specify areas to be reformed in order.”

  Looking at the top of the operation panel 50, “Please create a pasting area” is displayed. Below that, there is a picture of the building with the left side painted in the first color as “Create left side”. It is displayed. Below that, a picture of a building with the right side painted in the second color is displayed as “Create right side”. Below that, a picture of the building as the “other side” is displayed.

  Buttons 501 to 506 labeled “rectangle” and “polygon” are arranged on the right side of the picture of each building.

  A button 501 is a button for creating a rectangular region belonging to the left side of the building, and a button 502 is a button for creating a polygonal region belonging to the left side of the building. The area created after operating these buttons is displayed in the first color indicating that the area belongs to the left side.

  A button 503 is a button for creating a rectangular region belonging to the right side of the building, and a button 504 is a button for creating a polygonal region belonging to the right side of the building. The area created after operating these buttons is displayed in the second color indicating that the area belongs to the right side.

  Button 505 is a button for creating a rectangular area that does not belong to the left or right side of the building, and button 506 creates a polygonal area that does not belong to the left or right side of the building. It is a button to do. The area created after operating these buttons 505 and 506 is displayed in a third color indicating that the area does not belong to the left side or the right side.

  When the button 501 or 502 is clicked, in order to inform the user that an area belonging to the left side will be created, the vertical and horizontal straight lines on the left side are displayed in a grid pattern in the work area 40 as shown in FIG. Is displayed.

  When the button 503 or 504 is clicked, in order to inform the user that an area belonging to the right side will be created, the vertical and horizontal straight lines on the right side are displayed in a grid pattern in the work area 40 as shown in FIG. Is displayed.

  When the button 505 or 506 is clicked, a grid-like horizontal line and vertical line are not displayed in the work area 40 in order to inform the user that an area that does not belong to the left side or the right side will be created.

  When any one of buttons 501, 503, and 505 for creating a rectangular area is operated, only that button is highlighted, and then any two points (start point and end point) on the image of the work area 40 are designated. Only one rectangular area with these two points in the diagonal direction can be created. The created area is displayed in a fourth color indicating that it is the currently selected area. When one area is created, the reverse display of the button is canceled, and when the next area is created, it is created after clicking any of the buttons 501 to 506 again.

  When one of the buttons 502, 504, and 506 for creating a polygonal area is operated, only that button is highlighted, and then, by specifying any of a plurality of points on the image of the work area 40, Only one polygonal region having the plurality of points as vertices can be created. The created area is displayed in a fourth color indicating that it is the currently selected area. When one area is created, the reverse display of the button is canceled, and when the next area is created, it is created after clicking any of the buttons 501 to 506 again.

  When the Nth area (N ≧ 2) is created, only the Nth area is displayed in the fourth color indicating that the area is currently selected, and the first to (N−1) areas are displayed. The eye area is the first color for the area belonging to the left side, the second color for the area belonging to the right side, and the third color for the area not belonging to either the left side or the right side. Is displayed. By color-coding the regions created in this way, the currently selected region and the unselected region can be distinguished, or the region belonging to the left side and the region belonging to the right side, and also belonging to either the left or right side. Consideration is given so that it is possible to grasp at a glance which areas are not present.

  The first color indicating that the region belongs to the left side, the second color indicating that the region belongs to the right side, and the region that does not belong to the left side or the right side. Needless to say, the third color and the fourth color indicating the currently selected region are different from each other.

  FIG. 14A is an explanatory diagram showing a procedure for creating a rectangular region. Fig. (A) shows the creation of a rectangle belonging to the left side, Fig. (B) shows the creation of a rectangle belonging to the right side, and Fig. (C) shows how to create a rectangle that does not belong to either the left or right side. ing. The figure (a) or (b) in FIG. 14A is a figure which cannot be created unless all four points of a rectangle (strictly speaking, a quadrangle) are designated. Based on the three-dimensional information acquired in the dimension information input step S2, the rectangle belonging to the left side is created along the grid line of FIG. 13A, and the rectangle belonging to the right side is shown in FIG. 13B. Since it is created along a grid line, it can be created simply by specifying two diagonal points (start point a and end point b).

  The points a and b can be specified by clicking and dragging the start point a and releasing it at the end point b. Since any vertex of the rectangle can be used as the start point, the area can be easily created. It is said.

  FIG. 14B is an explanatory diagram showing a procedure for creating a polygonal region. As shown in (b) of FIG. 14B, when a plurality of points b, c, d, and e are designated starting from the starting point a and the end point f is double-clicked, each point is set as a vertex. The polygon is completed. Instead of double-clicking the end point f, the start point a may be clicked again. A complex polygon can also be created by first creating a polygon with a small number of vertices and then adding vertices. For example, as shown in (b) of FIG. 14B, first, a polygon having points a, c, d, and f as vertices is created, and this already created polygon area is clicked with the mouse 2a. When the button 507 for “add polygon vertex” is clicked, only one polygon vertex can be added thereafter. For example, when the line segment a-c is clicked with the mouse 2a, a polygonal vertex is added at the position b '. Drag this to the position of point b. In the same manner, after clicking the “add polygon vertex” button 507 and clicking the line segment df with the mouse 2a, a polygon vertex is added at the position of e ′. Drag this to the position of point e. In this way, when creating a complex polygon, even if one or two points are forgotten to be specified, they can be added later.

  Further, in order to deform the figure composed of the vertices a, b, c, and d in (c) of FIG. 14B, each vertex must be moved one by one. When the function is turned ON, by dragging one of the vertices α, β, γ, and δ of the frame surrounding the polygon as shown in (c) of FIG. As shown in (d) of b), a deformed polygon can be created by simultaneously moving a plurality of vertices a, b, c, and d. In the example of (d) in FIG. 14B, only one vertex γ of the frame is moved to γ ′, but a plurality of vertices a, b, c, and d are simultaneously moved and crushed as a whole. It can be seen that it can be transformed into a figure as shown.

  If there is an area to be deleted among the already created areas, the area is selected by clicking with the mouse 2a, and when the “delete” button 509 is operated, one of the areas displayed in the fourth color is displayed. Only the area is deleted. When a plurality of areas are selected by clicking the “group” button 508, these areas are grouped and can be deleted at once.

  When it is desired to redo the area creation step S10 from the beginning, if the reset button 56 provided below the operation panel 50 is operated, it is possible to return to the state at the time of the first transition to that step.

  By the way, in the system of the present invention, each region of the box indicating the top surface, the floor surface, the roof surface, the furniture, etc. can be created in the region creation step S10, and the operation panel 50 in FIG. A button 510 corresponding to the ceiling surface, a button 511 corresponding to the floor surface, a button 512 corresponding to the roof surface, and a button 513 corresponding to the box are provided.

  For example, when the button 512 corresponding to the roof surface is clicked with the mouse 2a, a dialog box BX1 as shown in FIG. 15A is displayed on the work area 40, for example. In the dialog box BX1, an input field 600 for inputting an angle with respect to a wall surface serving as a reference surface, radio buttons 601a and 601b for selecting a wall surface serving as a reference when creating a roof, a confirmation button 602, and a cancel button 603 are displayed. Has been. In the dialog box BX1, the user selects a wall surface serving as a reference when creating the roof with the radio button 601a or 601b and inputs an angle in the input field 600. This angle input is performed by gradient input (base: height = 10: X) or degree input (notation of 360 degrees). The gradient input may of course be an input format such as a fractional gradient (base / height = 10 / X).

  Thus, when the input confirmation button 602 is clicked to confirm the input, the dialog box BX1 disappears, and the same mouse 2a operation is performed as in the polygonal area designation described above, so that the roof area is matched with the image 41. create. Note that the inclination angle input in the roof region creation step is applied as the drawing direction when the material is pasted in the pasting mode described later.

  In addition, the roof area can be created by the procedures of eaves entrance / exit, roof shape selection such as a gable, gable, and the like, and the roof gradient input procedure, and the creation of the roof area in the area creation system 10 can be omitted.

  When creating a ceiling or floor area, click the button 510 or 511 to select the attribute of the area to be created, and then perform the same mouse 2a operation as the polygon area designation described above. Thus, a ceiling surface area or a floor surface area is created in accordance with the image 41. Note that an angle is applied to the drawing direction when the material is pasted in the pasting mode to be described later in the step of creating the ceiling surface area or the floor surface area. That is, the drawing control module 5d performs a material pasting process on the lower surface side of the region corresponding to the ceiling surface, and displays it in a drawing direction orthogonal to the wall surface. For the area corresponding to the floor surface, the material is pasted on the upper surface side and displayed in a drawing direction orthogonal to the wall surface.

  The box button 513 is a button for creating a rectangular parallelepiped on the assumption that it is orthogonal to the wall surface, and for creating an area for simplifying the creation of an extension room or a veranda area. For example, instead of the dialog box BX1 in FIG. 15 (a), as shown in FIG. 15 (b), an input field 604 for inputting the width, depth, and height of the box in mm units and a wall surface serving as a reference plane are selected. A dialog box BX2 provided with radio buttons 605a and 605b, an input confirmation button 602, and a cancel button 603 is displayed on the work area 40. The user inputs the width, depth, and height of the box in mm in the input field 604 of this dialog box 2 and selects the wall surface as the reference plane on which the box is to be placed with the radio button 605a or 605b and clicks the button 602. Then, the dialog box BX2 disappears, and a picture of a box (not shown) is displayed in a form arranged in parallel adjacent to the selected reference wall. FIG. 16A shows a case where the type of display mode selected at the time of initial setting is an external appearance.

  After this placement, the mouse 2a can be used to drag the box picture, translate it along the reference wall and drop it at the desired position, and change the placement position. Reference plane).

  When the material is pasted in the image pasting step S12 described later, the same material may be pasted on the entire surface of the box, or another material may be pasted separately for each surface. For example, it is possible to create an extension room or a veranda for the exterior type, and to create furniture such as a chiffon by attaching different materials for each surface in the interior (interior) type.

  If it is desired to fix the area every time the above-mentioned area is created, it can be fixed at the creation position by clicking the area fixing check field 59a of the operation unit 59, and if the check field 59b is clicked, the two areas are connected. If you drag and move one area with the mouse 2a and drop it in the vicinity of the other area, even if the drop position is a little rough, the automatically dropped area becomes the other area. It can be automatically connected by adsorption. Similarly, if the check column 59b is clicked also when connecting the line segments at the time of area creation, the adsorption connection can be automatically performed by the same operation.

  When it is desired to move to the next step, when the “next” button 57 provided below the operation panel 50 or the mask button 23 of the tool bar 20 is operated, the state shifts to the state shown in FIG.

  FIG. 16A corresponds to the mask creation step S11. Next, the mask creation step S11 will be described. In the mask creation step S11, when it is not desired to attach an exterior material to a part (for example, a window, an entrance door, a rain part, etc.) in the region specified in the region creation step S10, the region is cut through that region. This cut-out area is called a mask.

  FIG. 16A is a screen in the initial state of the mask creation step S11, and the mask button 23 of the tool bar 20 is displayed in a color different from other buttons. The operation guide 30 is instructed to “Specify the area of the window or door with a mask. It is displayed in color.” Looking at the upper part of the operation panel 50, “Please create a mask area” is displayed, and an “add” button 514 and a “delete” button 515 are arranged below it. One of these buttons 514 and 515 is in an operated state. In an initial state, an “add” button 514 is in an operated state. If a mask area is specified while the “add” button 514 is operated, the mask is added to the specified area. Also, when a mask area is specified while the “delete” button 515 is operated, the mask is deleted from the specified area. The functions of the buttons 501 to 506 shown in the figure used for creating or deleting a mask are the same as the functions of the buttons 501 to 506 used for creating an area. Note that the mask color selection unit 516 can select any of the three primary colors so that the mask color can be easily distinguished from the surrounding colors. Further, the mask may be displayed in different colors depending on whether it belongs to the left side, the right side, or any other region. Further, a button 517 for selecting a brush for painting an arbitrary area by operating the mouse 2a is provided. With the button 517 selected by clicking the brush, the mouse 2a is filled with the left button pressed. When the cursor placed on the area is moved, the brush size line input in the input field 518 is drawn under the control of the drawing control logic 5d so that the area can be filled.

  Here, the reason for providing separate mask creation and mask deletion functions is to create a large mask that covers all windows, for example, when multiple windows of the same height are arranged in a row. Then, it is possible to easily create a high-precision mask by deleting the mask between windows, or create a mask along a complicatedly shaped member such as a rain gutter or a ventilation hood. Since it is cumbersome to do, cover the whole with a large mask, and then scrape the surroundings little by little using the mask deletion function, so that even masks with complex shapes can be created easily It is. If the display magnification of the image 41 in the work area 40 is set to a large value such as 200% or 400% in the display magnification setting field 201, the fine part of the mask can be easily corrected by repeating addition and deletion. .

  If it is desired to start over from the beginning of the mask creation step, the reset button 56 provided below the operation panel 50 can be operated to return to the state at the time of initial transition to that step. When it is desired to move to the next step, when the “next” button 57 provided below the operation panel 50 or the sticking button 24 of the toolbar 20 is operated, the state shifts to the state shown in FIG.

  FIG. 16B corresponds to the image pasting step S12. Next, the image pasting step S12 will be described.

  In this image pasting step S12, an image of an exterior material or a roof material is pasted in the region specified in the region creating step S10 described above. In addition to attaching exterior and roofing materials, exterior parts such as entrance doors, windows, rain gutters, lights, and trees can also be placed.

  FIG. 16B is a screen in the initial state of the image pasting step S12, and the pasting button 24 of the toolbar 20 is displayed in a color different from the other buttons. The operation guide 30 is instructed that “Please click on the area where you want to change the image data. If you select a material from the operation panel, the image will change.” On the operation panel 50, a screen for selecting a material is displayed. First, a category such as exterior material, roofing material, rain gutter, color, etc. is selected using the category selection column 521 of the pasting material, and when any material is selected from the material name selection column 522, the display of the material is displayed. The material is displayed in a column 523. When the mouse cursor is placed on the displayed material, the product name, size, and remarks are displayed in the material description column 524. If a favorite material is found, any area on the image 41 in the work area 40 is clicked with the mouse 2a so that one area is selected, and then the material displayed in the material display field 523 is selected with the mouse. When the user clicks 2a, an image of the material can be pasted on the selected area. Clicking the grouping button 526 and then clicking a plurality of areas with the mouse 2a allows a plurality of areas to be selected at the same time, and the same material is pasted to the plurality of areas in one operation. You can also. Furthermore, the same material may be pasted to a plurality of areas collectively grouped according to the surface direction in the area creation step S10 described above.

  Since the three-dimensional angle information is input in the above-described three-dimensional information input step S2, the stretched exterior material and roof material also follow the grid lines as shown in FIG. 13 (a) or FIG. 13 (b). Drawn using perspective. That is, when there are repeated patterns on the exterior material and the roofing material, the pattern is drawn larger as it approaches the near side, and the pattern is drawn smaller as it moves farther away. Thereby, a feeling of depth is given to the image after pasting.

  Further, since the three-dimensional dimension information is input in the above-described three-dimensional information input step S2, images of the exterior material and the roof material can be pasted in a pattern close to the actual size. Furthermore, by multiplying the unit price per dimension by the pasting area, it is possible to estimate the renovation cost by calculating the material cost and labor cost. With regard to this estimation function, an “estimate” button may be added to the toolbar 20 or the operation panel 50 so that the estimate of the renovation cost can be displayed at any time during the editing operation. Either the save button 27 or the end button 13 can be displayed. When you click or, the dialog "Do you want to display the renovation cost estimate? (Yes: Y / No: N)" is displayed, and the estimate is displayed only when "Yes" is entered. It may be configured.

  FIG. 16C shows a screen in which an estimate list is displayed by a pop-up window. The estimate list can be edited on the display screen, and file writing is also possible. The display area, the number of sheets, the amount of money, and the total amount of money are not editable items. As for the correction area, the same value as the display area is displayed at the first display, and after the second correction, this correction area is displayed. Also, the number of sheets is calculated based on the area and the shape of the created area, how many standard areas (material size of the material) can be pasted, and the amount is calculated by multiplying the unit price per number of areas and the number of parts. , Not only the area but the number of hot springs. When the “estimate” button is operated, the CPU unit 4 calculates an estimate list under the control of each module 5a to 5d, displays the total number of display areas in units of materials, and corrects the estimate list. The displayed estimate list is edited, a value is entered in an input box (not shown), and the list is recalculated simultaneously with the confirmation. When the “export” button 610 is clicked, the contents of the estimate list are written in a separate file in the CSV format and stored in the storage device 3. When a “close” button 611 in FIG. 16C is clicked, the pop-up window is closed and the estimate list disappears from the screen.

  Now, even when the dimension input is omitted in the above-described three-dimensional information input step S2, if the enlargement / reduction button 525 of the pasting magnification is used, the pasting (pasting) magnification can be enlarged or reduced by the designated magnification. For example, when the enlargement or reduction button is clicked from the state shown in (b) of FIG. 16D, the pasting material is enlarged or reduced as shown in FIGS.

  By the way, when it is necessary to adjust the joint between the materials when the material image is pasted in the image pasting step S12, the top / bottom / left / right buttons of the joint adjusting button section 527 can be adjusted by clicking with the mouse 2a. it can. In this case, the state of the joint can be confirmed on the screen.

  By the way, in the above-mentioned area creation step S10, it is possible to designate an area as shown in FIG. 14A that does not belong to the right side or the left side as shown in FIG. 14C. For example, parts such as lights and trees around the building Can also be arranged. In the pasted image, the vertical and horizontal sizes are registered for parts such as lights and trees, and a flag indicating that the parts are displayed without tiling is shown in FIG. It is recorded in the image setting file in such a format. Therefore, if the three-dimensional dimension information is input in the above-described three-dimensional information input step S2, the enlargement / reduction ratio when these parts are pasted on the image can be automatically calculated, and the actual size is displayed on the image. Can be displayed. As a result, after selecting an image, it is possible to paste the image on a portion where no area has been created, such as dropping it in the work area. In addition, by storing the shape data of the 3D object, even when the orientation of the part is changed, it is possible to project and display the two-dimensional image at the actual size.

  In addition, when the dimension input is omitted in the above-described three-dimensional information input step S2, it is effective to change the size after arrangement in order to make it appear more realistic. To change the size, the display mode switching operation unit 58 switches the display mode to “wire frame” and moves the points a and b in the area (c) of FIG. Change the size of. After that, if the display mode is returned to “texture”, the parts whose display magnifications in the vertical and horizontal directions are changed are displayed. In addition, when parts are attached to the areas shown in (a) and (b) of FIG. 14 (a), a perspective is given along the grid lines of FIG. 13 (a) or FIG. 13 (b), respectively. Needless to say, the displayed parts are displayed.

  In the image display in the work area 40, only the original image is displayed in the image reading step S1, the three-dimensional information input step S2, and the region creating step S10, the mask creating step S11, the image pasting step S12, and a shadow effect adding step S13 described later. Then, three types of original image, wire frame, and texture can be selected.

  For example, when “original image” is selected, the image read in the image reading step S1 is displayed, and when “wire frame” is selected, the region designated in the region creating step S10 or the mask creating step S11 is placed on the original image. When the “texture” is selected, an image with the material pasted in the image pasting step S12 is displayed on the original image.

  Again, if the reset button 56 provided below the operation panel 50 is operated, it is possible to return to the state at the time of the first transition to that step. When it is desired to move to the next step, when the “next” button 57 provided below the operation panel 50 or the shadow button 25 of the toolbar 20 is operated, the state shifts to the state shown in FIG.

  FIG. 17A corresponds to the shadow effect adding step S13. Next, the shadow effect adding step S13 will be described. In this step S13, the brightness and shadow of the pasted exterior material and roof material are adjusted.

  FIG. 17A is a screen in an initial state of the shadow effect adding step S13, and the shadow button 25 of the tool bar 20 is displayed in a color different from other buttons. The operation guide 30 is instructed to “adjust brightness and shading and adjust to the original image”. The operation panel 50 is provided with a slide bar 531 for adjusting the brightness and a slide bar 532 for adjusting the shadow, and on top of that, “Drag and drag to adjust brightness and shadow” is displayed.

  One area on the image 41 of the work area 40 is clicked with the mouse 2a to select one area.

  When this area is selected, the original image is converted into a grayscale image, and the process of transmitting the selected area through the converted image as a background is performed under the control of the drawing control module 5d. Next, when the slide bar 531 for adjusting brightness is adjusted, the opacity of the area is adjusted and the reflection of the gray value of the background changes.

  Here, when the opacity is changed by operating the slide bar 531 with respect to the gray scale of the original image, the threshold value setting column 533 is used to cut the reflected value with a certain gray value. Is set by moving the pointer shown in FIG. By repeating the opacity adjustment by the slide bar 531 and the threshold setting, when the original image is dark or the wall is dirty, only the shadow to be reflected can be extracted and reflected in the selected area. It is.

  When the shadow adjustment slide bar 532 is adjusted, the luminance value of the three primary colors of each point of the material pasted on the selected region is changed to a value modulated by the average luminance value of the original image in the region, When the modulation degree is deep, the shadow becomes deep, and when the modulation degree is shallow, the shadow becomes light.

  This will be described with reference to an image of a building shown in FIG. Since there are irregularities in the building, a shadow is always produced when it is exposed to light. However, if the material is pasted only in the above-described image pasting step S12, both the shadow part and the bright part of the building have the same brightness. . In order to make this a more realistic and beautiful finish, the brightness and shadow are adjusted.

  First, looking at the roof portion of the building in FIG. 17B, it can be seen that there are a high-lightness portion and a low-lightness portion. Therefore, even if the same roofing material is pasted, it is possible to obtain an image with no sense of incongruity by lowering the brightness of the shadowed portion of the building and increasing the brightness of the portion exposed to light.

  In addition, when looking at the wall portion of the building shown in FIG. 17B, it can be seen that there is a shadow directly under the roof or under the bay window. Further, when the shadows formed on the roof and the wall are seen, it can be seen that dark portions and thin portions are mixed. This means that shadows are darker in areas where there are double shadows. In such a case, it is not possible to adjust a realistic shadow only by adjusting the brightness. Therefore, the average luminance value of each point of the original image is acquired as an average value of luminance of several points to several tens of points, for example, and the luminance value of the pasted material image is modulated with the average luminance value of each point of the original image. As a result, the shadow in the original image is reflected on the image of the material superimposed on it. As a result, the material after pasting can be shaded.

  Clicking the grouping button 526 and then clicking a plurality of areas with the mouse 2a makes it possible to select a plurality of areas at the same time. An effect can be imparted.

  Again, if the reset button 56 provided below the operation panel 50 is operated, it is possible to return to the state at the time of the first transition to that step. Further, when it is desired to move to the next step, if the “Next” button 57 provided below the operation panel 50 or the save button 27 on the toolbar 20 is operated, the work up to that point is saved as a file in a predetermined format. can do. When the end button 28 on the toolbar 20 or the end button 13 on the title bar is operated, the program can be ended.

  The image 41 is provided with a step of inputting the position where the sun is arranged, and the position of the sun as the light source for the building shown in the image 41 is displayed by the sub window by the T0P view or the SIDE view. A function to enter and determine by the user in the input field, or a function to automatically determine the position of the sun from the longitude and latitude of Japan by inputting the direction and date and time for the building, and a function to input the brightness of the sun Based on these inputs, the position of the shadow due to sunlight on the building on the image 41 is drawn so as to overlap the shadow region on the building and presented to the user. good. When the solar position is automatically determined based on the longitude and latitude, brightness data corresponding to the sun position is stored in the storage device 3 in advance, and the sun brightness is automatically set by searching this data. You can also. In addition, by adding a color (transparent gray) to the shadow area, the brightness of the light area and the shadow area can be manipulated without deteriorating the original color accuracy of the pasting material. Of course, the color of the material pasted on the area may be directly operated to display light and dark.

  Now, in the flowchart of FIG. 2, the step switching process is automatically performed using a variable Step. If there is a step switching button pressing event, it is first checked whether the reset button 56 is clicked. If the reset button 56 is clicked, the process returns to the three-dimensional information input step S3, and the variable Step also returns to the initial value. If not, the process proceeds to a step with a variable Step. If, for example, Step = 1 which is an initial value is set, the process proceeds to an area creation step S10. When the “Next” button 57 is pressed on the operation panel 50 in each step, the variable Step is incremented by 1 and Step = 2, and the process proceeds to the mask creation step S11. When the “Next” button 57 is pressed, the variable Step is incremented by 1 and Step = 3, and the process proceeds to the image pasting creating step S12. When the “Next” button 57 is pressed, the variable Step is incremented by 1 and Step = 4, and the process proceeds to the shadow effect adding step S13. When the “Next” button 57 is pressed, the variable Step is incremented by 1 and Step = 5, and the process is terminated. The processing is also terminated when the end button 13 or the save button 27 is pressed. Of course, when the reset button 56 is clicked, the process returns to the three-dimensional information input step S3. As described above, when any of the step switching buttons 22 to 25 of the toolbar 20 is pressed halfway, the value of the variable Step is forcibly set to n = m-21 according to the number m of the pressed button. , You can go back to the previous step.

  When the image reading button 21 on the toolbar 20 is clicked, the process returns to the image reading step.

  FIG. 18A is an explanatory diagram showing an outline of the area creation processing in the area creation step S10. Here, a case where a rectangular region is created will be described. First, get the face information. For example, if the button 501 is pressed, a rectangular area on the left side is created. At this time, by acquiring plane information on the left side as shown by the grid lines in FIG. 13A, a rectangular region can be created simply by specifying two diagonal points. As the two-dimensional information of the object, when the point a in FIG. 14A (A) is clicked with the mouse 2a on the screen, this is acquired as the start point coordinates (xa, ya). Next, when point b in FIG. 14A is clicked with the mouse 2a on the screen, this is acquired as end point coordinates (xb, yb). If a line passing through these start point coordinates (xa, ya) and end point coordinates (xb, yb) is drawn along the plane information of the left side figure, a rectangle on the left side can be created, and this is registered as area information. . At the same time, a rectangular figure on the left side is drawn over the original image on the image 41 in the work area 40. Specifically, the luminance information RGB of the three primary colors at each coordinate (x, y) is changed to a specific color. In addition, the process of color-coding the area with the above-described first, second, and third colors is as follows. For each figure, figure 1 = (left side, rectangle, start point coordinate a, end point coordinate b), figure 2 = (right side) , Polygon, coordinate a, coordinate b, coordinate c, coordinate d), figure 3 = (others, rectangle, start point coordinate a, end point coordinate b), etc. For the left side figure, it is the first color, the right side figure is the second color, the left side and the right side are the third color, and the selected figure is the second color. The four colors of luminance information RGB (,,) of the three primary colors of each point constituting the figure are switched and displayed.

  FIG. 18B is an explanatory diagram showing an outline of the mask creation process in the mask creation step S11. Almost the same as the area creation process described above, but with the addition of a process for obtaining a flag for distinguishing between mask addition and deletion, logical addition when adding a mask, and negation when deleting a mask. The only difference is that masks are added and deleted in the logical product operation.

  FIG. 18C is an explanatory diagram showing an outline of the shadow effect adding process in the shadow effect adding step S13. A flag for identifying whether the slide bar 531 or 532 is selected is “change in brightness” or “change in shadow”, and the intensity of change in brightness based on the height of the selected slide bar The brightness or shadow is changed by multiplying the luminance information RGB (,,) of the three primary colors of each point in the bitmap information of the work area by a predetermined coefficient (<1) according to the acquired information. is there.

In addition, the screen configuration illustrated in the accompanying drawings is merely an example, and is not intended to be limited to the illustrated screen configuration.

  The image replacement method in the architectural image of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.

  In the description of the present embodiment, the “side surface” in the case of the left side surface and the right side surface of a house means a substantially vertical wall surface that constitutes a building, but it is not necessarily an outer wall surface. The present invention can also be applied to the wall surface. In other words, the method of the present invention may be applied not only to the replacement simulation of outer walls and roof materials, but also to the replacement simulation of interior wall materials, floor materials, and ceiling materials.
