The three-dimensional catalog distribution system 1 is a computer (hereinafter, referred to as a “server”) 11 on the catalog distribution side. A computer (hereinafter, referred to as a “client”) 12 on the receiving side is connected to the communication network 8. The server 11 is installed in an interior goods sales company such as furniture, and the client 12 is installed in a sales office or an event hall of the goods sales company, or a computer of each home is used as a client. In the three-dimensional catalog distribution system 1, a three-dimensional catalog is distributed from the server 11 to the client 12 based on a distribution request from a browser or the like of the client 12, and an image for a product catalog is displayed on the client 12.

FIG. 3 is a block diagram showing a functional configuration as an image display device realized by the CPU 21, the ROM 22, the RAM 23, the fixed disk 24, and the like when the CPU 21 operates in accordance with the program 80. The functions realized by the above are shown. When the client 12 is a dedicated computer installed in a store or the like, the function of the processing unit 3 may be realized by a dedicated electric circuit, or an electric circuit may be partially used.
[0022]
FIG. 4 is a diagram illustrating a flow of a process in which the client 12 displays a three-dimensional object over a background image. The actual operation of the client 12 is performed by processing an input event by the operator, but is simplified in FIG. Hereinafter, the function and operation of the client 12 will be described with reference to FIG. 3 and along FIG.
[0023]
First, a background image is selected by the operator performing input through the input unit 26 (step S11). For example, in a window on the display 25 illustrated in FIG. 5 (the entire screen may be a single window), the operator selects a desired background image from the background image selection unit 41 and the selected image is selected. The background image data is output from the background image database 82 of the fixed disk 24 to the processing unit 3, and the background image 52 is displayed on the main display unit 42 on the window.
At this time, the display magnification of the background image 52 (corresponding to the size of the image including a part that is not displayed) may be made adjustable by an operator's input. Subsequently, when the operator selects the viewpoint change mode from the operation mode selection unit 43, the three-dimensional coordinate axes 51 are displayed on the background image 52 as shown in FIG.
[0024]
Here, a model of a geometrical positional relationship between the background image 52 and the three-dimensional coordinate axis 51 (hereinafter, referred to as a “view model”) will be described. FIG. 7 is a diagram for explaining a view model. In the view model of the client 12, a virtual camera 53 facing the background image 52 is assumed, and the three-dimensional coordinate axis 51 is provided on the background image 52 side of the virtual camera 53. Then, an image obtained when the virtual camera 53 captures an image with the three-dimensional space defined by the three-dimensional coordinate axes 51 superimposed on the background image 52 is displayed on the main display unit 42.
[0025]
In the client 12, a process corresponding to an operation of changing the distance between the virtual camera 53 and the three-dimensional coordinate axis 51 by the camera operation unit 311 based on the input from the operator is further performed. At this time, the angle of view of the virtual camera 53 may be changed by interlocking the size change of the background image 52 (ie, changing the distance between the background image 52 and the virtual camera 53). In addition, the three-dimensional coordinate axis operation unit 312 performs a process of moving or rotating the three-dimensional coordinate axis 51 based on the input of the operator. In the fusion unit 31, a process of superimposing the background image 52 and the three-dimensional space by the three-dimensional coordinate axes 51 is performed, and the superimposed image is displayed on the display 25.
[0026]
The operator operates the mouse 26b or the like to move and rotate the three-dimensional coordinate axes 51 displayed on the background image 52, and to make the three-dimensional coordinate axes 51 coincide with the state of the background image 52. Is set (step S12). That is, based on an operation input by the operator, a region (hereinafter, referred to as a “floor region”) 521 in the background image 52 and a region (hereinafter, referred to as a “window-side region”) indicating a wall surface on the window 522a side. .) 522 is aligned with the Y-axis of the three-dimensional coordinate axis 51, and the boundary 525 between the window-side region 522 and the region 523 indicating the other wall surface (hereinafter referred to as “wall surface region”) 523. A setting is performed in which the Z-axis of the three-dimensional coordinate axis 51 is aligned, and the X-axis of the three-dimensional coordinate axis 51 is aligned with a boundary 526 between the wall surface area 523 and the floor area 521. Thereby, the regions 521 to 523 in the background image 52 and the regions in which the XY plane, the YZ plane, and the ZX plane in the three-dimensional space defined by the three-dimensional coordinate axis 51 are projected on the background image 52 respectively match.
[0027]
The display of the three-dimensional coordinate axis 51 is performed in real time while the three-dimensional coordinate axis 51 is being operated, so that the operator can easily and accurately set the three-dimensional coordinate axis 51. FIG. 8 is a diagram illustrating a state after the three-dimensional coordinate axis 51 is set for the background image 52.
[0028]
When the three-dimensional coordinate axis 51 is set with respect to the background image 52 as described above, subsequently, the arrangement of the three-dimensional object in the three-dimensional space defined by the three-dimensional coordinate axis 51 and the three-dimensional object The layout change is performed according to the operation of the operator. In the following description, the XY plane, the YZ plane, and the ZX plane defined by the three-dimensional coordinate axes 51 shown in FIG. 8 are referred to as a floor, a window side, and a wall, respectively.
[0029]
In the window shown in FIG. 8, when the operator changes the operation mode selection unit 43 to the object movement mode, the display of the three-dimensional coordinate axis 51 disappears, and the state shifts to a state in which the three-dimensional object is handled. When the client 12 receives a selection of a desired product from the three-dimensional object selection unit 44 in the lower right part of the window via the input unit 26, a three-dimensional object indicating the selected product is displayed in the three-dimensional object preview unit 45. Will be displayed.
[0030]
For example, when “chair A” is selected from the three-dimensional object selection unit 44, a three-dimensional object 61 indicating “chair A” (hereinafter, “chair 61”) is three-dimensional as shown in FIG. It is displayed on the object preview section 45. In FIG. 8, "chair A" in the three-dimensional object selection unit 44 is surrounded by a broken line to indicate that it is in a selected state. Further, the three-dimensional object may be displayed while slowly rotating at the time of preview so that the three-dimensional object can be grasped accurately.
[0031]
Subsequently, the operator performs an operation of moving the chair 61 displayed on the three-dimensional object preview unit 45 from the three-dimensional object preview unit 45 onto the background image 52 (for example, a drag and drop operation using the mouse 26b). As a result, the client 12 recognizes that the operation of adding the three-dimensional object to the background image 52 has been performed (step S13), and the data of the chair 61 is output to the fusion unit 31 from the three-dimensional object database 81 of the fixed disk 24. You.
[0032]
The fusion unit 31 selects the floor surface as the arrangement surface based on the data of the chair 61 (step S14), and the bottom surface of the chair 61 predetermined as the contact surface with the floor surface (that is, the end of the foot of the chair 61). The chair 61 is arranged in the three-dimensional space in a state where the floor (surface formed by the section) and the floor are in contact with each other (step S15). Then, as shown in FIG. 9, the chair 61 is superimposed on the background image 52 of the main display unit 42 and displayed (step S16).
[0033]
In the state shown in FIG. 9, when the operator performs an operation of moving the chair 61 via the mouse 26b (for example, by dragging while clicking the left button of the mouse 26b), the three-dimensional object operation unit in FIG. A signal indicating the movement of the chair 61 is sent from the layout unit 321 to the layout unit 32 (step S18), and the chair 61 moves on the floor in the three-dimensional space in the direction and distance according to the operation in the layout unit 32 (step S19). ). Then, the moved chair 61 is displayed superimposed on the background image 52 (step S16). As a result, the chair 61 moves as if it were along the floor in the background image 52.
[0034]
When the operator performs an input for instructing rotation (for example, an operation of clicking and dragging the right button of the mouse 26b) (step S18), the three-dimensional object operation unit 321 vertically moves the floor. A process of rotating the chair 61 by an angle corresponding to the operation about the predetermined central axis is performed (step S19), and the rotated chair 61 is displayed on the background image 52 via the layout unit 32 (step S19). Step S16).
[0035]
Further, when the operator performs an input for changing the size (for example, an operation of dragging while clicking the middle button of the mouse 26b) (step S18), the three-dimensional object operation unit 321 sets the three-dimensional coordinate axes. A process of changing the scale of 51 is performed (step S19). As a result, the size of the displayed three-dimensional object is relatively changed (step S16). FIG. 10 is a diagram showing a state in which the chair 61 of FIG. 9 has been moved and rotated by the processing in step S19. The manner in which the size of the three-dimensional object is changed will be described later.
[0036]
The process of changing the layout of the three-dimensional object is repeated at high speed during the operation of the operator (steps S18, S19, S16, S17). Therefore, actually, the movement, rotation, and change of the size of the three-dimensional object are performed almost in real time according to the operation of the operator. Thus, the operator can efficiently perform the layout change operation while looking at the main display unit 42.
[0037]
As described above, in the client 12, which is an image display device, the three-dimensional coordinate axes 51 are set in advance in accordance with the background image 52, and the arrangement surface in the three-dimensional space and the contact surface of the three-dimensional object indicating the product come into contact with each other. In this state, the three-dimensional object is arranged in the three-dimensional space. Thereby, the background image 52 and the three-dimensional object can be displayed in a superimposed manner in a natural state. Further, by moving or rotating the placed three-dimensional object on the placement surface, a natural layout change can be easily realized.
[0038]
As shown in FIG. 4, the client 12 can repeat the process of adding a three-dimensional object onto the background image 52 as needed. FIG. 11 is a diagram illustrating a state where a three-dimensional object 62 indicating “chair B” and a three-dimensional object 63 indicating “table A” (hereinafter, referred to as “table 63”) are added.
In the client 12, for example, an operation target is selected based on the position of the cursor when the mouse 26b is clicked, and the operator can move or rotate for each three-dimensional object. Here, the three-dimensional object has an absolute size, and the size of the three-dimensional object in the three-dimensional space is determined by the scale of the three-dimensional coordinate axis 51. As a result, in the client 12, it is realized that the comparison of the size between the three-dimensional objects is easily performed visually.
[0039]
Next, another example of the three-dimensional object arrangement processing (steps S14 and S15 in FIG. 4) in the client 12 will be described.
[0040]
In the window shown in FIG. 11, when the operator selects “wall-mounted television” from the three-dimensional object selection unit 44, a three-dimensional object 64 indicating “wall-mounted television” (hereinafter, “wall-mounted television 64”) is three-dimensional. It is displayed on the object preview section 45. Then, when the operator performs an input (for example, a drag-and-drop operation using the mouse 26b) to specify a desired position on the window side area 522 or the wall area 523 with respect to the arrangement position of the wall-mounted television 64 (step). S13), the wall-mounted television 64 is displayed at the designated position (Steps S14 to S16). That is, by receiving the input of the layout designation position on the background image 52 by the operator, the layout surface in the three-dimensional space is selected from the window side surface or the wall surface, and the position on the selected layout surface is specified. , The wall-mounted television 64 is displayed at the designated position on the background image 52.
[0041]
FIG. 12 is a diagram illustrating an image when a window side surface (window side region 522) is designated as an arrangement surface of the wall-mounted television 64, and FIG. 13 is a diagram illustrating an image when a wall surface (wall surface region 523) is designated. It is. The wall-mounted television 64 in FIGS. 12 and 13 can be further moved or rotated on the arrangement surface, similarly to the chair 61 described above.
[0042]
As described above, depending on the product, the arrangement surface associated with the data of the three-dimensional object can be selected from a plurality of surfaces predetermined based on the three-dimensional coordinate axis 51, and the arrangement surface is determined based on the operation of the operator. Is selected and determined. Thereby, more various product arrangements are realized. In the above example, the description has been made with respect to a product in which the window side surface or the wall surface can be selected. For example, in the case of a product that can be placed on the floor or mounted on the wall, the floor surface, the window side surface and the wall surface can be selected. It is said.
[0043]
Next, still another example of the three-dimensional object arrangement processing will be described. When the operator selects “vase” from the three-dimensional object selection unit 44, a three-dimensional object (hereinafter, referred to as “vase”) 65 indicating “vase” is displayed on the three-dimensional object preview unit 45 as shown in FIG. Is done. Then, the operator uses the mouse 26b or the like to change the arrangement position with respect to the floor area 521 or the area on the background image 52 corresponding to the plane on the already arranged three-dimensional object (for example, the upper surface of the table 63). By performing an input for designating (step S13), the vase 65 is displayed at the designated position (steps S14 to S16).
[0044]
That is, the data of the three-dimensional object indicating the vase 65 specifies that not only the floor surface but also the top surface of the already arranged three-dimensional object can be selected as the arrangement surface. By receiving the input of the arrangement designation position, the arrangement surface of the vase 65 is selected and determined from the top surface and the floor surface of the table 63 in the three-dimensional space, and the contact surface (bottom surface) of the selected arrangement surface and the vase 65 The vase 65 is arranged in a three-dimensional space in a state where the vase 65 is in contact with the vase 65. FIG. 14 shows a case where the upper surface of the table 63 is selected as the arrangement surface of the vase 65.
[0045]
As described above, in the client 12, when a product that can be arranged on the surface that is predetermined with the three-dimensional coordinate axis 51 as a reference and the surface on the already arranged three-dimensional object is selected. The operator selects an arrangement surface from these surfaces, and the three-dimensional object of the product arranged on the arrangement surface and the background image 52 are displayed in a superimposed manner. As a result, a more diverse arrangement of commodities is realized. The arrangement surface on the already arranged three-dimensional object is not limited to the top surface, and may be a side surface or a bottom surface (for example, the bottom surface of an object arranged on a wall).
[0046]
Next, an example in which the size of the three-dimensional object is changed in accordance with the background image 52 will be described. The absolute size of the three-dimensional object is determined as described above, and the size of the three-dimensional object in the three-dimensional space is determined based on the scale of the three-dimensional coordinate axis 51. Therefore, when the operator performs an operation to change the size of the three-dimensional object in a state where the plurality of three-dimensional objects are arranged, the scale of the three-dimensional coordinate axis 51 is changed, and the size and the size of the three-dimensional object are changed. The interval is changed uniformly. Here, in the client 12, a three-dimensional object for comparison is prepared in order to easily change the size of the three-dimensional object to an appropriate size according to the background image 52.
[0047]
In the window shown in FIG. 14, when the operator selects “person (170 cm)” from the three-dimensional object selection unit 44 and performs an object adding operation on the background image 52, the “person (170 cm)” is displayed. A dimensional object (hereinafter, referred to as “person”) is displayed on the main display unit 42 as a comparison object. FIG. 15 is a diagram illustrating a state where a person 66 has been added. The person 66 is a three-dimensional object having a size (that is, height) of 170 cm in the Z direction in a three-dimensional space defined by the three-dimensional coordinate axes 51. Therefore, by superimposing and displaying the background image 52 and the person 66 whose height is known, the person 66 can be easily changed to an appropriate size with respect to the background image 52.
[0048]
For example, by comparing the height of the window 522a on the background image 52 with the height of the person 66, it is possible to determine whether the size of the three-dimensional object is appropriate. If the person 66 in FIG. 15 determines that the height is lower than the height of the window, the operator changes the scale of the three-dimensional coordinate axis 51 by performing an input to increase the size of the three-dimensional object. The size of each three-dimensional object on the image 52 is changed simultaneously. FIG. 16 is a diagram illustrating an image when each three-dimensional object in FIG. 15 is enlarged.
[0049]
As described above, the client 12 includes the comparison object having a known size in the plurality of three-dimensional objects displayed on the background image 52, so that each of the three-dimensional objects has an appropriate size corresponding to the background image 52. It can be easily changed. In particular, in the case of the background image 52 indicating indoors, the scale of the three-dimensional coordinate axis 51 can be accurately adjusted by using an upright person whose height is known as the comparison object.
[0050]
Here, as another function for adjusting the size of the three-dimensional object to the background image 52, a process in which the client 12 measures a desired distance between two points on the background image 52 will be described. FIG. 17 is a diagram showing a flow of the operation of the client 12 in the distance measurement. The operation shown in FIG. 17 is provided as a process executed in response to the operation of the operator in the routine repeated in step S17 in FIG.
[0051]
For example, in FIG. 16, when the specification of the points P1 and P2 on the wall area 523 by the operator is received by the client 12 (step S21), the distance L1 between the points P1 and P2 on the wall defined by the three-dimensional coordinate axis 51 is determined. Is calculated in the processing unit 3 (step S22), and the calculation result is displayed on the display 25 (for example, in another window) (step S23). The measurement of the distance between the two points can be performed in any of the floor area 521, the window area 522, and the wall area 523. As described above, by measuring the distance between the two points input on the reference plane defined by the two coordinate axes of the three-dimensional coordinate axes 51, the operator can determine the position of the three-dimensional coordinate axes 51 set in the background image 52. The scale can be grasped, and the size of the three-dimensional object can be easily adjusted to an appropriate one.
[0052]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible.
[0053]
The program 80, the three-dimensional object database 81, and the background image database 82 do not necessarily need to be downloaded via the communication network 8, but may be read via the recording medium 9 (see FIG. 2). Alternatively, only the program 80 may be stored in the client 12, and only the data of the background image 52 or the data of the three-dimensional object selected by the background image selection unit 41 or the three-dimensional object selection unit 44 may be downloaded from the server 11.
[0054]
The client 12 may be any device having a function as a computer, for example, a portable information terminal.
[0055]
The plane predetermined based on the three-dimensional coordinate axis 51 as the arrangement plane corresponding to the three-dimensional object does not necessarily need to be the floor surface or the wall surface (side surface of the window) as described above, and may be in the three-dimensional space. It may be another fixed surface (for example, a surface separated by a predetermined distance from a wall surface).
[0056]
