Description

  The present invention relates to a system for performing a simulation of placing a three-dimensional model on a dedicated sheet on which a coded pattern is printed and placing an object.

  There is known a system for acquiring entry contents by filling in a dedicated paper or the like on which a coded pattern such as a dot pattern is printed using a dedicated pen type device. The pen-type device calculates the position coordinates on the dedicated paper by reading the dot pattern on the dedicated paper and performing a predetermined calculation process or the like.

  Pen-type input devices called “electronic pens” and “digital pens” have emerged as an example of devices that apply the above-mentioned principle, and representative examples of such devices include “Anot Pen” developed by Anoto in Sweden. (Anoto pen) "is known. Anotopen is used as a pair with dedicated paper on which a predetermined dot pattern is printed. In addition to the normal ink-type pen tip, the Anoto pen is equipped with a small camera for reading the dot pattern on the dedicated paper and a data communication unit. When a user writes characters on the special paper with an annotation pen, or puts a check mark on the image designed on the special paper, the small camera displays the dot pattern printed on the special paper as the pen moves. Detect and calculate the position coordinates of the pen on the dedicated paper. Based on the movement of the calculated position coordinates, entry information such as characters and images written by the user is acquired. Patent Documents 1 and 2 describe examples of coordinate calculation methods in Anotopen.

  By the way, it is known to perform a simulation as to whether or not an actual object can be placed at a place by placing a three-dimensional model on a two-dimensional drawing. Examples of such a method are described in Patent Documents 3 and 4.

  There has also been proposed a method for determining whether a vehicle can pass through a road by software calculation. For example, the emergency vehicle route search system described in Patent Document 5 allows an emergency vehicle to pass based on data such as road width, general vehicle width, and emergency vehicle width stored in the map information database. It is determined whether or not.

  Further, Patent Document 6 proposes a game apparatus configured to read a dot pattern by providing a camera with a lens facing downward in a figure used as a board game piece.

  As described above, it is often performed to simulate whether a real object can be placed at a place by placing a three-dimensional model on a two-dimensional drawing. Specifically, the following examples are given. One example is a case where a furniture model is placed on a floor plan of a room, and “whether it can be arranged at the place”, “whether it is in harmony with other furniture”, or the like is checked. The second example is a case where a model of an emergency vehicle is placed on a house map, and “how many vehicles can be stopped”, “how many vehicles can be stopped”, etc. are confirmed at the time of the earthquake disaster.

  However, as in Patent Documents 3 and 4 and the like, a mere model has only to visually confirm the relationship with the drawing, and thus the positional information is not accurate. In addition, since the previous position information cannot be recorded, it was not possible to look back and review again.

  Software that simulates movement on a computer has also appeared as in Patent Document 5, but the intuition of moving a model with a human hand has been lost, and those who are not used to operating computer software can confirm it. There is a problem of being unable to concentrate on.

  On the other hand, since the example described in Patent Document 6 does not have information such as the size of a figure, it cannot be applied to applications that require accurate simulation.

  An object of the present invention is to provide an object arrangement simulation system, method, program, and a three-dimensional model used therefor, which can accurately determine whether or not an actual object can be arranged using a three-dimensional model and dedicated paper. And

[Basic principle]
First, the basic principle of the present invention will be described. A technique for encoding position coordinates in a virtual space in the form of a dot pattern and expressing it on a medium such as paper is known. A typical example using this technology is the Anoto digital pen. The coordinate reading technology (device) used in this digital pen is embedded in a three-dimensional model and moved on a dedicated sheet on which a dot pattern is printed. The terminal device processes the information read by the device at that time, and displays the screen or outputs the sound, so that the user can accurately grasp the location of the model placed on the dedicated paper.

  In addition, by holding information such as the shape and size of this three-dimensional model using various methods described later, there is a mismatch between the relationship with other models. It is possible to accurately check whether or not it exists. Thus, it can be determined whether or not an actual object corresponding to the three-dimensional model can be placed in an actual place or space indicated by the dedicated sheet. In addition, the presentation method of the determination result does not ask | require the form, such as an image display to a display apparatus, and an audio | voice output.

  Hereinafter, a plurality of embodiments distinguished according to the method for retaining shape information of the three-dimensional model will be described.

[First Embodiment]
In 1st Embodiment, a some coordinate detection device (coordinate detection means) is provided in a solid model, and arrangement | positioning and a shape of a solid model are specified based on the some coordinate obtained from them. Specifically, the first embodiment has the following basic configuration.
(1) A plurality of coordinate detection devices are provided along the outline of the three-dimensional model.
(2) The coordinate detection devices are grouped for each three-dimensional model.
(3) When arranged on a sheet on which a dot pattern (coded pattern) is printed, each coordinate detection device obtains coordinates on the sheet and transmits the coordinate data to an external device.
(4) The external device calculates an area in which the three-dimensional model is arranged based on the coordinate data transmitted from each grouped coordinate detection device, and displays the calculated area on a display (display device) or the like. Further, if the arrangement of the three-dimensional model is inappropriate, the notification is made by voice or display.

  Hereinafter, the first embodiment will be described in detail. In the first embodiment, the present invention is applied to a simulation in which furniture is arranged in a room layout. FIG. 1 shows a schematic configuration of an object arrangement simulation system (hereinafter also simply referred to as “simulation system”) according to the first embodiment. As illustrated, the simulation system 100a includes a furniture model (three-dimensional model) 20a, a sheet (dedicated sheet) 30a on which a floor plan is printed, and an external device 50a. In addition, the scale of floor plan and the scale of the furniture model 20a are the same.

  A dot pattern (coded pattern) 32 is printed on the paper 30a, and a room floor plan is printed thereon. The dot pattern 32 is printed with ink containing carbon that absorbs infrared rays. On the other hand, the floor plan is printed with ink having no absorption in the infrared region. The dot pattern 32 and the floor plan may be printed on the paper at the same time, or one of them may be printed separately first.

  Here, the dot pattern 32 will be described in detail. FIG. 2 is a diagram for explaining the relationship between the dots of the dot pattern 32 printed on the paper 30a and the values to which the dots are converted. As shown in FIG. 2, each dot of the dot pattern 32 is associated with a predetermined value depending on its position. That is, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left and right are shifted from the reference position of the grid (intersection of the vertical and horizontal lines). The value of each dot can be further converted into a first bit value for the X coordinate and a second bit value for the Y coordinate. The position coordinates on the paper 30a are determined by the combination of the information thus associated.

  FIG. 3A shows an arrangement of a certain dot pattern 32. As shown in FIG. 3 (a), 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a unique pattern can be obtained no matter which part of the paper 30a is taken 6 × 6 dots. . The dot pattern 32 formed by these 36 dots holds position coordinates (for example, on which position the dot pattern is located on the dedicated paper). FIG. 3B is a diagram in which each dot shown in FIG. 3A is converted into a value associated with the regularity shown in FIG. 2 according to the shift direction from the reference position of the lattice. This conversion is executed by the coordinate detection device 10 described later.

  The furniture model 20 a is a furniture model such as a chiffon, for example, and includes a plurality of coordinate detection devices (coordinate detection means) 10. Specifically, four coordinate detection devices 10 are provided in the vicinity of the four corners of the furniture model 20a that is a substantially rectangular parallelepiped. Thereby, the furniture model 20a acquires the coordinates of the four corners of the position where the furniture model 20a is arranged on the paper 30a. The furniture model 20a is formed of, for example, resin.

  A schematic configuration of the coordinate detection device 10 is shown in FIG. The coordinate detection device 10 includes a communication unit (transmission means) 11, a memory (storage unit) 13, an image processor 14, a pressure sensor 15, a CMOS camera (hereinafter simply referred to as “ It is called a "camera".) 16 and LED17 which irradiates infrared rays.

  The pressure sensor 15 detects that the coordinate detection device 10 is placed on the paper 30a by detecting the pressure with which the coordinate detection device 10 is pressed against the paper 30a, and outputs a signal indicating that to the image processor 14. Send to.

  When the pressure sensor 15 detects that it is arranged on the paper 30a and the image processor 14 receives and activates a signal corresponding thereto, the image processor 14 activates the LED 17 to emit infrared rays and Then, the sheet 30a is driven to image at a predetermined cycle (about 50 to 100 times / second). The camera 16 images the dot pattern 32 printed on the paper 30 a at a predetermined cycle and transmits it to the image processor 14.

  When the image processor 14 receives a dot pattern image obtained by capturing the dot pattern 32 from the camera 16, the image processor 14 executes predetermined processing based on the dot pattern 32 to generate position coordinate data on the paper 30 a.

  Here, since carbon absorbs infrared rays, the infrared rays irradiated by the LED 17 are absorbed by the carbon contained in the dots at the dot portions. Therefore, the dot portion has a small amount of infrared reflection, and the portion other than the dot has a large amount of infrared reflection. Therefore, the area of the dot containing carbon and the other area can be distinguished from the difference in the amount of reflected infrared light by photographing with the camera 16. Even if a ruled line or a frame is printed in the photographing region, the ink such as the ruled line or the frame has no absorbability in the infrared region, so that the dot pattern 32 can be recognized. Note that the shooting area by the camera 16 is a range including a size of about 2 mm × about 2 mm as shown in FIG.

  The memory 13 stores identification information (ID) of each coordinate detection device 10 provided in the furniture model 20a. This ID is used to group a plurality of coordinate detection devices 10 provided on the same furniture model 20a in the external device 50a.

  The communication unit 11 transmits data to the external device 50a using, for example, the Bluetooth (registered trademark) system. In the present embodiment, each communication unit 11 of the four coordinate detection devices 10 provided in the furniture model 20 a is stored in advance in the memory 13 and the position coordinate data of the coordinate detection device 10 obtained by the image processor 14. The ID of the coordinate detection device 10 being transmitted is transmitted to the external device 50a. Therefore, the external device 50a receives the position coordinate data and the ID from each of the four communication units 11 in the furniture model 20a.

  The external device 50a is configured as a terminal device such as a personal computer (PC). FIG. 5 shows a functional configuration of the external device 50a. As illustrated, the external device 50a includes a receiving unit 51, an arrangement determining unit 52, a storage unit 53, a display unit 54, and a notification unit 55. Physically, an antenna device, a processor such as a CPU, a ROM, a RAM, and a hard disk Are constituted by a memory, a display, a speaker and the like.

  The receiving means 51 receives position coordinate data and ID from each coordinate detection device 10 of the furniture model 20a.

  The storage unit 53 stores arrangement environment data indicating an arrangement environment of objects in the floor plan printed on the paper 30a. For example, in the floor plan shown in FIG. 1, the arrangement environment data is data indicating the position and range of a veranda, a beam, a front door, a wall, and the like. Moreover, the memory | storage part 53 has linked | related and memorize | stored ID memorize | stored in each memory 13 of the some coordinate detection device 10 provided in one furniture model 20a. Therefore, the storage unit 53 stores the IDs of the plurality of coordinate detection devices 10 provided in the furniture model 20a in groups for each furniture model 20a.

  The arrangement determining unit 52 groups the position coordinate data for each furniture model 20a based on the received ID. In other words, when receiving the ID, the arrangement determining unit 52 collates with the IDs grouped and stored for each furniture model 20a in the storage unit 53, and a plurality (four) provided in the same furniture model 20a. The position coordinate data of the coordinate detection device 10 is grouped and stored in the storage unit 53. The four position coordinate data thus obtained indicate the position of the furniture model 20a on the paper 30a. That is, the rectangular area formed by connecting the four position coordinate data corresponds to the area where the furniture model 20a is arranged on the paper 30a. Therefore, the arrangement determining means 52 determines the arrangement of the furniture model 20a on the paper 30a based on the position coordinate data and the ID received from each coordinate detection device 10 of the furniture model 20a. In addition, since coordinate data is acquired from each of the four coordinate detection devices 10, the arrangement | positioning determination means 52 can also specify the direction by which the furniture model 20a is arrange | positioned.

  The display means 54 displays the image corresponding to the floor plan printed on the paper 30a on the screen of the display using the layout environment data. Furthermore, the display means 54 displays the arrangement of the furniture model 20a determined by the arrangement determining means 52 on the floor plan. A display example of the floor plan is shown in FIG. In this example, a floor plan is displayed on the display screen of the display, and a hatched area 70 indicating the arrangement of the furniture model 20a is further displayed.

  The notification means 55 collates the arrangement of the furniture model 20a with the arrangement environment data, and determines whether or not the arrangement of the furniture model 20a is appropriate. When the furniture model 20a is arranged in an area without an obstacle as in the example of FIG. 6, the notification unit 55 determines that the arrangement of the three-dimensional model is appropriate and does not output a warning. On the other hand, when the arrangement of the furniture model 20a is inappropriate in light of the arrangement environment indicated by the arrangement environment data, for example, when the furniture model 20a is arranged so as to overlap the position of the veranda or the beam, the notification unit 55 Issues a warning that the placement is incorrect. This warning may be displayed on the display screen of the display or may be output by sound output from a speaker. Examples of warnings include text messages and voices such as “Furniture model is improperly placed!”.

  FIG. 7 shows a flowchart of the object arrangement simulation process according to the first embodiment. Here, for convenience of explanation, the four coordinate detection devices 10 provided in the furniture model 20a are referred to as coordinate detection devices A to D.

  First, in each of the coordinate detection devices A to D, the pressure sensor 15 detects that the furniture model 20a is placed on the paper 30a (step S101), and the camera 16 and the image processor 14 detect the coordinate detection devices A to D. Are calculated (step S102). Then, the communication unit 11 transmits the position coordinate data of the coordinate detection devices A to D and the IDs of the coordinate detection devices A to D stored in the memory 13 to the external device 50a (step S103).

  In the external device 50 a, the receiving unit 51 receives the position coordinate data and the IDs of the coordinate detection devices A to D from the coordinate detection devices A to D, and the arrangement determination unit 52 refers to the storage unit 53 while referring to the storage unit 53. Based on the ID of D, the received position coordinate data is grouped (step S104). Thereby, a set of position coordinate data corresponding to one furniture model 20a is obtained, and the arrangement of the furniture model 20a is determined. Next, as illustrated in FIG. 6, the display unit 54 displays a floor plan on a display (display device) (step S105) and displays the arrangement of the furniture model 20a (step S106).

  Further, the notification means 55 refers to the layout environment data to determine whether or not the furniture model 20a is improperly arranged (step S107), and if it is improper, issues a warning to that effect. Notification is made (step S108). Thus, the object arrangement simulation process is completed.

  Thus, according to this 1st Embodiment, arrangement | positioning of the furniture model 20a can be determined correctly by utilizing the position coordinate of the some coordinate detection device 10 provided in the furniture model 20a. In addition, by checking the layout environment corresponding to the floor plan, it is determined whether or not the furniture model 20a is properly positioned, and if it is inappropriate, a warning is issued to notify the user. Can do.

  In the present embodiment, as illustrated in FIG. 6, after the position of the furniture model 20a is displayed on the display screen, if the furniture model 20a is moved on the paper 30a, the position data of the moved furniture model 20a and the like are obtained. It is transmitted to the external device 50a, and the position 70 of the furniture model 20a on the display screen can be moved almost in real time. And if the notification means 55 notifies that the arrangement of the furniture model 20a is inappropriate, the inappropriate notification can be canceled by moving the furniture model 20a. Therefore, by arranging a plurality of furniture models 20a on the paper 30a on which the floor plan is drawn so that improper notification is not made, the user can easily arrange the furniture on the ideal floor plan. Can be arranged.

  Hereinafter, the second embodiment will be described in detail. In the second embodiment, the present invention is applied to a simulation for determining whether an emergency vehicle can pass through a road on a map. Hereinafter, differences from the first embodiment will be described.

  FIG. 8 shows a schematic configuration of a simulation system according to the second embodiment. As illustrated, the simulation system 100b includes an emergency vehicle model 20b (hereinafter simply referred to as a “vehicle model (three-dimensional model)” 20b), a paper (dedicated paper) 30b on which a map is printed, and an external device 50b. Is provided.

  On the paper 30b, a dot pattern 32 is printed with ink containing carbon, and a map is printed with ink containing no carbon.

  As shown in FIG. 9, the vehicle model 20b includes four coordinate detection devices 10 at substantially four corners. The configuration of each coordinate detection device 10 is the same as that of the first embodiment shown in FIG. Therefore, the vehicle model 20b acquires the position data of the four corners from the four coordinate detection devices 10 when placed on the paper 30b. Further, the memory 13 of each coordinate detection device 10 stores an ID for grouping the four coordinate detection devices 10 provided in the same vehicle model 20b. The map printed on the paper 30b and the scale of the vehicle model 20b are the same.

  The external device 50b is configured similarly to the external device 50a of the first embodiment, and the functional configuration is shown in FIG.

  FIG. 10 shows an example of a display screen on the display displayed on the external device 50b in the second embodiment. The external device 50b stores data corresponding to the map printed on the paper 30b as arrangement environment data in the storage unit 53, and the display means 54 displays the map on the display screen using this data. Further, the arrangement determining means 52 determines the arrangement (including position and orientation) of the vehicle model 20b based on the position data from the four coordinate detection devices 10, and the hatched area indicating the position of the vehicle model 20b on the map 71 is displayed.

  FIG. 11 shows a flowchart of an object arrangement simulation process according to the second embodiment. Here, for convenience of explanation, the four coordinate detection devices 10 provided in the vehicle model 20b are referred to as coordinate detection devices A to D.

  First, in each of the coordinate detection devices A to D, the pressure sensor 15 detects that the vehicle model 20b is placed on the paper 30b (step S201), and the camera 16 and the image processor 14 detect the coordinate detection devices A to D. Is calculated (step S202). Then, the communication unit 11 transmits the position coordinate data of the coordinate detection devices A to D and the IDs of the coordinate detection devices A to D stored in the memory 13 to the external device 50b (step S203).

  In the external device 50b, the receiving unit 51 receives the position coordinate data and the IDs of the coordinate detecting devices A to D from the respective coordinate detecting devices A to D, and the arrangement determining unit 52 refers to the storage unit 53 and the coordinate detecting devices A to D. Based on the ID, the received position coordinate data is grouped (step S204). Thereby, a set of position coordinate data corresponding to one vehicle model 20b is obtained, and the arrangement of the vehicle model 20b is determined. Next, as illustrated in FIG. 10, the display unit 54 displays a map on the display screen (step S205) and displays the arrangement of the vehicle model 20b (step S206).

  Further, the notification means 55 refers to the arrangement environment data to determine whether or not the arrangement of the vehicle model 20b is improper (step S207), and if it is improper, issues a warning to that effect. Notification is made (step S208). Examples of the improper arrangement of the vehicle model 20b include a case where the vehicle width of the vehicle model 20b exceeds the road width, and a case where the vehicle model 20b straddles the road and the building. In addition, as a warning when the vehicle model 20b is improperly arranged, a display such as “emergency vehicle cannot pass by that arrangement!” Or voice output may be mentioned. Thus, the object arrangement simulation process is completed.

  Also in the second embodiment, once the vehicle model 20b is arranged on the paper 30b and displayed on the display screen as shown in FIG. 10, the vehicle model 20b is moved to move the position of the vehicle model 20b on the display screen (hatched area). 71) can be moved in real time.

  In the second embodiment as well, an information system in which common information (group information) is included in the ID stored in the memory 13 of each coordinate detection device A to D (10) provided in one vehicle model 20b. If the group information of the ID stored in the memory 13 is included for each vehicle model 20b, the storage unit 53 of the external device 50b does not store the IDs of the coordinate detection devices A to D in groups. However, the arrangement determining means 52 recognizes that the same group information included in the received ID is the coordinate detection devices A to D provided in the same vehicle model 20b, and the position coordinate data thereof. Can be grouped.

[Third Embodiment]
In the third embodiment, one coordinate detection device is provided in the three-dimensional model, and information such as the shape and size of the three-dimensional model is stored in the coordinate detection device. Then, the arrangement and shape of the three-dimensional model are specified based on the position coordinate data detected by the coordinate detection device and information such as the shape. Specifically, the third embodiment has the following basic configuration.
(1) One coordinate detection device is provided in the three-dimensional model.
(2) The memory of the coordinate detection device stores the shape and size occupied by the three-dimensional model, and the position of the coordinate detection device in the model shape (hereinafter collectively referred to as “shape related information”). .
(3) When the coordinate detection device is arranged on a paper on which a dot pattern (coded pattern) is printed, the coordinate detection device obtains coordinates on the paper and obtains an arrangement angle of the coordinate detection device with respect to the paper.
(4) The coordinate detection device transmits coordinate data, an arrangement angle, and shape related information to an external device.
(5) The external device calculates a region where the three-dimensional model is arranged based on each data transmitted from the coordinate detection device, and displays it on a display device or the like. Further, if the arrangement of the three-dimensional model is inappropriate, the notification is made by voice or display.

  Hereinafter, the third embodiment will be described in detail. In the third embodiment, the present invention is applied to a simulation in which furniture is arranged in a room layout. FIG. 12 shows a schematic configuration of the simulation system according to the third embodiment. As illustrated, the simulation system 100c includes a furniture model (three-dimensional model) 20c, a sheet (dedicated sheet) 30c printed with a floor plan, and an external device 50c.

  The paper 30c is configured similarly to the paper 30a in the first embodiment. That is, a dot pattern (coded pattern) 32 is printed on the paper 30c, and a room floor plan is further printed thereon. The dot pattern is printed with ink containing carbon that absorbs infrared rays. On the other hand, the floor plan is printed with normal ink not containing carbon.

  The furniture model 20 c includes one coordinate detection device 10. The configuration of the coordinate detection device 10 is basically the same as that of the first embodiment shown in FIG. 4, but differs in the following points.

  First, the image processor 14 generates the position coordinate data on the paper 30c using the dot pattern 32, and detects the arrangement angle of the coordinate detection device 10 with respect to the paper 30c. Here, the “arrangement angle” is a rotation angle of the coordinate detection device 10 arranged on a plane defined by the paper 30c. This will be described with reference to FIG. FIG. 13 is a schematic diagram in plan view of the arrangement of the two coordinate detection devices 10a and 10b on the paper 30c. Now, let one radial direction of the coordinate detection device 10 be a reference direction D. Further, the arrangement angle when the coordinate detection device 10 is arranged in a state where the reference direction D coincides with the Y direction of the X and Y coordinates is set to “0 degree”, and the arrangement angle is defined in the clockwise direction therefrom. In this case, in FIG. 13, the arrangement angle of the coordinate detection device 10a is “0 degree”. On the other hand, the arrangement angle of the coordinate detection device 10b is “90 degrees” because the reference direction D is rotated 90 degrees in the clockwise direction. Note that the above-described method for defining the arrangement angle is an example, and other defining methods may be adopted.

  Next, a method for determining the arrangement angle will be briefly described. As described above, the dot pattern 32 is printed so as to be unique at any position on the paper 30c. Accordingly, when the dot pattern 32 including a predetermined number (for example, 6 × 6) of dots is read by the camera 16, the dot pattern 32 corresponds to one place on the paper 30c and is disposed relative to the paper 30c. Is also uniquely determined.

  In principle, the dot pattern 32 read by the coordinate detection device 10 at an arrangement angle of 0 degree with respect to the paper 30c is the same as the dot pattern 32 formed in one place on the paper 30c as it is (that is, without being rotated). Match. Further, the dot pattern 32 read by the coordinate detection device 10 at a relative arrangement angle of 90 degrees with respect to the paper 30c does not coincide with the dot pattern 32 formed on the paper 30c as it is, but if rotated 90 degrees the paper It coincides with the dot pattern 32 formed at one place on 30c. Therefore, a process of detecting pattern matching is performed while rotating the dot pattern 32 read by the coordinate detection device 10 relative to the dot pattern 32 on the paper 30c, and coordinate detection when pattern matching is obtained. The rotation angle of the device 10 may be set as the arrangement angle. Note that the above-described Patent Document 2 describes a specific method for detecting the arrangement angle of the digital pen with respect to the paper, and this method may be applied to the arrangement angle detection method in the present embodiment.

  The memory 13 stores the ID of the coordinate detection device 10 and the shape related information of the furniture model 20c. The ID of the coordinate detection device 10 is used to distinguish the data received from the plurality of furniture models 20c on the external device 50c side for each furniture model. The shape related information includes the shape and size occupied by the furniture model 20c (that is, the projection shape and size from the top to the bottom of the furniture model 20c) and the position of the coordinate detection device 10 in the shape of the furniture model 20c. Since these pieces of information are known when the furniture model 20 c provided with the coordinate detection device 10 is created, the information is stored in the memory 13 of the coordinate detection device 10 in advance.

  The communication unit 11 collects the position coordinate data of the coordinate detection device 10 generated by the image processor 14, the arrangement angle with respect to the paper 30 c, and the ID and shape related information of the coordinate detection device 10 stored in the memory 13. To 50c.

  Except for the above points, the function of each component of the coordinate detection device 10 is the same as that of the first embodiment.

  The external device 50c basically has the same configuration as the external device 50a of the first embodiment shown in FIG. 5, but the function of the arrangement determining means 52 is different from that of the first embodiment. As described above, the furniture model 20c is provided with only one coordinate detection device 10, and the external device 50c receives the position coordinate data, the arrangement angle, and the shape related information of the one coordinate detection device 10. Therefore, the arrangement determining means 52 determines the arrangement of the furniture model 20c on the paper 30c based on these. Specifically, the arrangement determining unit 52 determines the position on the paper 30c based on the position coordinate data. Next, the arrangement determining means 52 determines an area occupied by the furniture model 20c on the paper 30c based on the arrangement angle, the position of the coordinate detection device 10 on the furniture model 20c, and the shape and size occupied by the furniture model 20c.

  The external device 50c is the same as the external device 50a of the first embodiment except for the points described above. Therefore, when the arrangement of the furniture model 20c on the paper 30c is determined, the display unit 54 displays the floor plan and the area 70 of the furniture model 20c on the display screen as in FIG. Further, when the arrangement of the furniture model 20c is inappropriate with respect to the floor plan, the notification means 55 notifies that fact.

  FIG. 14 shows a flowchart of an object arrangement simulation process according to the third embodiment.

  First, in the coordinate detection device 10 provided in the furniture model 20c, the pressure sensor 15 detects that the furniture model 20c is arranged on the paper 30c (step S301), and the coordinate detection device is detected by the camera 16 and the image processor 14. Ten position coordinates and arrangement angles are calculated (step S302). Then, the communication unit 11 transmits the position coordinates and the arrangement angle of the coordinate detection device 10 and the ID and shape related information of the coordinate detection device 10 stored in the memory 13 to the external device 50c (step S303).

  In the external device 50c, the receiving means 51 receives the above data from the coordinate detection device 10, and the display means 54 displays a floor plan on a display (display device) based on the layout environment data (step S304). Next, as described above, the arrangement determination unit 52 determines the paper 30c based on the position coordinates and the arrangement angle of the coordinate detection device 10 and the ID and shape related information of the coordinate detection device 10 stored in the memory 13. The arrangement of the furniture model 20c is determined. Next, the display means 54 displays the arrangement of the furniture model 20c as illustrated in FIG. 6 (step S305).

  Further, the notification means 55 refers to the layout environment data to determine whether or not the furniture model 20c is improperly arranged (step S306), and if it is improper, issues a warning to that effect. Notification is made (step S307). Thus, the object arrangement simulation process is completed.

  Thus, according to 3rd Embodiment, the arrangement | positioning of the furniture model 20c can be determined correctly by utilizing the position coordinate and arrangement | positioning angle of the one coordinate detection device 10 provided in the furniture model 20c. . Also, by checking the layout environment corresponding to the floor plan, it is determined whether or not the layout of the furniture model 20c is appropriate, and if it is inappropriate, a warning is issued to notify the user. Can do.

  In the present embodiment, as illustrated in FIG. 6, after the position of the furniture model 20c is displayed on the display (display device), if the furniture model 20c is moved on the paper 30c, the position of the furniture model 20c after the movement is displayed. Data or the like is transmitted to the external device 50c, and the position 70 of the furniture model 20c on the display (display device) can be moved in real time.

  Further, as described above, when the position of the furniture model 20c is changed on the paper 30c, the position of the furniture model 20c at any time of the user is stored in the external device 50c. This is convenient when comparing several arrangements.

The paper 30f is the same as the paper 30d of the fourth embodiment.
The vehicle model 20f is basically the same as the vehicle model 20d of the fourth embodiment. However, only the ID of the coordinate detection device 10 is stored in the memory 13, and no shape related information is stored. Therefore, the communication unit 11 transmits the position coordinates and the arrangement angle detected by the coordinate detection device 10 and the ID of the coordinate detection device to the external device 50f.

  The external device 50f is basically the same as the external device 50d of the fourth embodiment. However, the storage unit 53 stores the shape-related information of each vehicle model 20f in association with the ID of the vehicle model 20f.

  FIG. 22 shows a flowchart of an object arrangement simulation process according to the sixth embodiment.

  First, in the coordinate detection device 10 provided on the vehicle model 20f, the pressure sensor 15 detects that the vehicle model 20f is placed on the paper 30f (step S601), and the camera 16 and the image processor 14 detect the coordinates. The position coordinates and the arrangement angle of the device 10 are calculated (step S602). Then, the communication unit 11 transmits the position coordinates and the arrangement angle of the coordinate detection device 10 and the ID of the coordinate detection device 10 stored in the memory 13 to the external device 50f (step S603).

  In the external device 50f, the receiving unit 51 receives each data from the coordinate detection device 10, and the display unit 54 displays a map on a display (display device) based on the layout environment data (step S604). Next, the arrangement determination unit 52, as described above, based on the position coordinates and the arrangement angle of the coordinate detection device 10, the ID of the coordinate detection device 10, and the shape related information stored in the storage unit 53, The arrangement of the vehicle model 20f on the paper 30f is determined. Next, the display means 54 displays the arrangement of the vehicle model 20f as illustrated in FIG. 17 (step S605).

  Further, the notification means 55 refers to the arrangement environment data to determine whether or not the arrangement of the vehicle model 20f is inappropriate (step S606), and if not appropriate, issues a warning to that effect. Notification is made (step S607). Examples of the improper arrangement of the vehicle model 20f include a case where the vehicle width of the vehicle model 20f exceeds the road width and a case where the vehicle model 20f straddles the road and the building. Further, as a warning when the vehicle model 20f is improperly arranged, a display such as “emergency vehicle cannot pass by the arrangement!” Or voice output may be mentioned. Thus, the object arrangement simulation process is completed.

  Also in the sixth embodiment, once the vehicle model 20f is placed on the paper 30f and displayed on the display (display device) as shown in FIG. 17, the vehicle model 20f is moved to move the vehicle model on the display (display device). The position 20f (shaded area 72) can be moved in real time.

  Further, the sixth embodiment can be applied to a case where a plurality of vehicle models 20f are arranged on a sheet 30f corresponding to a parking lot and a plurality of vehicles are simulated for parking.

  The present invention can be applied to a system that simulates whether or not an object can be placed in various environments.
