Description

[Technical Field]

[0001] The present invention relates to a partitioned space projection system that breaks down three-dimensional models of objects such as buildings and furniture into three-dimensional views and projects them onto partitioned surfaces within a partitioned indoor space, allowing objects such as buildings and furniture to be perceived with a sense of presence and reality. [Background technology]

[0002] Conventionally, a partitioned space projection system has been known that uses projection mapping technology to project the interior of a building as a three-dimensional view onto the floor and walls of a partitioned indoor space, allowing the internal structure of the building to be perceived with a sense of presence and reality, and is useful for designers or purchasers when designing or purchasing a building (see Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-164003 [Patent Document 2] Japanese Patent Publication No. 2020-096243 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] The partitioned space projection system described in Patent Document 1 projects the floor and wall surfaces of an indoor space such as an office in life-size onto the floor and wall surfaces of a virtual indoor space, and allows virtual components such as desks, chairs, and shelves to be freely positioned within the virtual indoor space, making it possible to easily and quickly set or change the position of components such as desks, chairs, and shelves in an indoor space such as an office.

[0005] In addition, the compartment space projection system described in Patent Document 2 projects at least a portion of the target data from architectural design data onto the floor or wall surfaces within a building, and when used as a guide for drawing marking lines, is designed to reduce the preparation work required to project the target data onto the floor or wall surfaces within a building by providing a distance measuring unit in the projection device.

[0006] However, neither of the compartment space projection systems described in Patent Documents 1 and 2 uses a three-dimensional model of an object such as a building or furniture, cuts its external or internal structure into appropriate cross sections, decomposes it into three-view drawings, and projects them onto the floor and walls, nor is it possible to project the object at life-size or at an appropriate magnification.

[0007] Furthermore, it was not possible to decompose furniture and other components installed in a building into three-dimensional views and recognize them three-dimensionally from each side.

[0008] The present invention has been made in consideration of the above-mentioned conventional problems, and aims to provide a partitioned space projection system that uses a three-dimensional model of an object such as a building or furniture, cuts its external or internal structure at appropriate cross sections, breaks it down into three-dimensional views, and can project them onto floors and walls, and can project the projection object at life-size or at an appropriate magnification, and further breaks down furniture and other components installed within a building into three-dimensional views so that they can be recognized three-dimensionally from each side. [Means for solving the problem]

[0009] In order to achieve the above object, the partitioned space projection system of the present invention is a partitioned space projection system comprising a partitioned space, a projection device, and an information processing device, The compartmented space is formed by a floor surface and two walls erected perpendicular to the floor surface, The projection device is composed of three projection devices supported by appropriate support members, and is configured to project images onto the floor and two walls, respectively. The information processing device comprises a computer main body, an input device, and an output device, The auxiliary storage device (hard disk) of the computer main body stores a partition space projection program and three-dimensional model data of the building model, The partition space projection program reads three-dimensional model data of the building model, draws the building model at a specified magnification, decomposes the building model into three-view drawings of a plan view, a front view, and a side view, draws the three-view drawing data, transmits the three-view drawing data to the projection device, and projects the three-view drawing onto the floor and two walls by the projection device.

[0010] Furthermore, the partition space projection program is characterized in that it decomposes an architectural model into three-view drawings of a plan view, a front view, and a side view, cuts the drawings at a specified cross section, creates a cross-section, transmits the three-view drawing or cross-section drawing data to the projection device, and projects the three-view drawing or cross-section drawing onto the floor and two walls by the projection device.

[0011] The partition space projection system is also characterized in that it can also create images of three-view drawings or cross-sectional view data of a building model.

[0012] Furthermore, the partition space projection system is further characterized by being able to appropriately cut the external or internal structure of a component model, such as furniture, to be installed in a building, into cross sections, decompose it into three-view drawings, and project it onto the floor and two walls.

[0013] Here, a position / rotation angle detection sensor may be installed on a component such as furniture to be installed in a building, and an observer may grasp the component within the compartmented space and hold it in a predetermined position and tilted state, causing the position / rotation angle detection sensor to detect the position and tilted state of the component.

[0014] Furthermore, the partitioned space projection system further stores a mixed reality space formation program and three-dimensional model data of furniture and other structural components in the auxiliary storage device (hard disk) of the computer main body, and is characterized in that the observer can view the real structural components and the virtual objects (images) superimposed on each other through MR goggles worn on the head. [Effects of the Invention]

[0015] According to the partitioned space projection system of the present invention, the external or internal structure of an object such as a building or furniture can be cut into appropriate cross sections, broken down into three-dimensional views, and projected onto the floor and two wall surfaces.The object can also be projected at life-size or at an appropriate magnification.Furthermore, furniture and other components installed within the building can be broken down into three-dimensional views and recognized three-dimensionally from each side, allowing objects such as buildings and furniture to be recognized with a sense of presence and reality, which can be of great use to designers or purchasers when designing or purchasing a building, or when selecting components such as furniture.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the partitioned space projection system of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The partitioned space projection system 100 of the present invention comprises a partitioned space 10, a projection device 20, and an information processing device 30, as shown in FIGS.

[0019] The compartment space 10 is defined by a floor surface 11 and a wall surface 12 (front surface) and a wall surface 13 (side surface) that are erected perpendicularly to the floor surface 11. In addition, in order to properly illuminate the compartment space 10 when necessary, a lighting device 15 consisting of a fluorescent lamp or the like is installed above the compartment space 10.

[0020] Projection device 20 is composed of three projection devices 21, 22, and 23 suspended and supported from the ceiling or the like by appropriate support members, and are configured to project images onto floor surface 11, wall surface 12 (front), and wall surface 13 (side), respectively.

[0021] The information processing device 30 comprises a computer main body 40 installed in a housing 40A, an input device 50 such as a keyboard 51 and a mouse 52, and an output device 60 such as a display 61 and a printer 62.

[0022] As shown in FIG. 5, the computer main body 40 is made up of a control device 41, an arithmetic unit 42, a main memory 43, an auxiliary memory device (hard disk) 44, and the like.

[0023] The auxiliary storage device (hard disk) 44 stores a partition space projection program 200, three-dimensional model data 310 of a building model 300, three-dimensional model data 510 of a component model 500 such as furniture, and the like.

[0024] 6, the partition space projection program 200 first reads the three-dimensional model data 310 of the building model 300 and draws the building model 300 by enlarging or reducing it to a specified magnification. Next, the building model 300 drawn at the specified magnification is decomposed into three views, namely, a plan view 321, a front view 322, and a side view 323, and drawn.

[0025] Furthermore, as shown in FIG. 6, a specified cross section is set in the three-view drawing, the building model 300 is cut at the specified cross section, cross sections 331, 332, and 333 are created, and the three-view drawing data or cross section data is transmitted to each of the projection devices 21, 22, and 23.

[0026] By receiving the three-view data or cross-sectional view data, the three projection devices 21, 22, and 23 project images corresponding to the three-view views of the building model 300, namely, the plan view 321, the front view 322, and the side view 323, onto the floor 11, the wall 12, and the wall 13 of the partitioned space 10, as shown in Figure 6.

[0027] Next, the information processing steps performed by the partitioned space projection program 200 will be explained in order for each processing step.

[0028] First, the power supply to the computer main body 40 of the information processing device 30 is turned on, the computer main body 40 is operated, the partitioned space projection program 200 stored in the auxiliary storage device (hard disk) 44 is read into the main storage device (main memory) 43, and the partitioned space projection program 200 is started.

[0029] Next, the three-dimensional model data 310 of the building model 300 stored in the auxiliary storage device (hard disk) 44 is read into the main storage device (main memory) 43 and temporarily stored in the main storage device (main memory) 43.

[0030] Next, on the magnification specification screen on the display 61, by inputting and specifying the drawing magnification of the building model 300 using an input device 50 such as a keyboard 51 or a mouse 52, the building model 300 can be enlarged or reduced and the magnification at which the image is projected can be determined.

[0031] Next, on the drawing creation screen on the display 61, click the three-orthographic drawing creation button, etc., to decide to create a three-orthographic drawing. As shown in Figure 6, three-orthographic drawing data is created that breaks down the building model 300 into three orthographic drawings of a plan view 321, a front view 322, and a side view 323 at the specified magnification, and can then be drawn.

[0032] Next, on the cross-section designation screen on the display 61, three views of a plan view 321, a front view 322, and a side view 323 are displayed, and the cross-section designation axes Xo, Yo, and Zo are displayed and designated as shown in FIG. 6 using an input device 50 such as a keyboard 51 or a mouse 52, and the planes containing these cross-section designation axes Xo, Yo, and Zo can be determined as the designated cross sections Pz (plane containing axes Xo and Yo), Py (plane containing axes Xo and Zo), and Px (plane containing axes Yo and Zo).

[0033] Next, on the drawing creation screen, click the cross-section creation button, etc., to decide to create a cross-section, and cross-section data will be created and drawn, cutting the building model 300 at the specified magnification along the specified cross sections Pz, Py, and Px of the plan view 321, front view 322, and side view 323, as shown in Figure 6.

[0034] Then, by storing this three-dimensional view data and cross-sectional view data in the auxiliary storage device (hard disk) 44, the three-dimensional view data or cross-sectional view data can be read out from the auxiliary storage device (hard disk) 44 as needed and transmitted to each projection device 21, 22, 23, thereby projecting images corresponding to the three-dimensional views or cross-sectional views of the plan view 321, front view 322, and side view 323 of the building model 300 onto the floor surface 11, wall surface 12, and wall surface 13 of the partitioned space 10, as shown in Figure 6.

[0035] Here, an information processing process is executed using the partition space projection program 200, and cross-sectional data 370 is created by specifying cross-sectional axis lines Xo, Yo, and Zo based on the three-dimensional model data 360 of the building model 350 as shown in Figure 7, and cutting the plane containing the cross-sectional axis lines Xo, Yo, and Zo at a cross section with the specified cross sections Pz, Py, and Px as the planes containing the cross-sectional axis lines Xo, Yo, and Zo.

[0036] Then, by transmitting the cross-sectional view data 370 to the three projection devices 21, 22, and 23, it was possible to project images corresponding to cross-sections of the floor plan 371, front view 372, and side view 373 of the building model 350 onto the floor surface 11, wall surface 12, and wall surface 13 of the partitioned space 10, as shown in Figure 8.

[0037] As shown in Figure 8, when images corresponding to three-dimensional views or cross-sectional views of the building model 350, namely, a plan view 371, a front view 372, and a side view 373, are projected, the cross-sectional designated axes Xo, Yo, and Zo are also projected and displayed on the plan view, front view, and side view, superimposed on the images corresponding to these three-dimensional views or cross-sectional views. Furthermore, by operating the controller 71 described later, these cross-sectional designation axes Xo, Yo, Zo can be moved parallel to the axis Yo, Zo direction in the case of axis Xo, or in the direction of axis Xo, Zo direction in the case of axis Yo, or in the direction of axis Xo, Yo direction in the case of axis Zo, or in the direction of axis Xo, Zo direction in the case of axis Yo.

[0038] Therefore, by operating the controller 71, the cross-section designated axes Xo, Yo, Zo can be translated in an appropriate direction, and new cross-section designated axes Xa, Ya, Za can be designated, and new designated cross sections Pz, Py, Px can be set as planes containing the cross-section designated axes Xa, Ya, Za. Furthermore, since the position data of the cross-sectional specified axes Xa, Ya, Za is synchronized with image data corresponding to a three-dimensional view or a cross-sectional view of the building model 350, images corresponding to cross-sectional views of the plan view, front view, and side view of the building model 350 at the newly specified cross sections Pz, Py, and Px can be projected onto the floor 11, wall surfaces 12, and wall surfaces 13 of the partitioned space 10.

[0039] Furthermore, the partition space projection system 100 of the present invention can project not only still images such as three-view drawings or cross-sections of the building model 300, but also images that change over time, that is, so-called video.

[0040] When projecting an image of a three-dimensional view or a cross-sectional view of the building model 300, an image projection program 400 such as that shown in Figure 9 can be added to the partition space projection program 200, or the image projection program 400 can be stored separately in an auxiliary storage device (hard disk) 44, and image data of the three-dimensional view or cross-sectional view of the building model 300 can be created in advance.

[0041] In this video projection program 400, a single moving image created for a three-orthographic view is read as video data, and in the same manner as the still image, the video data is divided into three-orthographic views or cross-sectional views to create each piece of video data. Also, considering that it may be difficult to understand what kind of building or object the image is about when it is projected, a preview image can also be projected on the three-view drawing for confirmation. This preview image is displayed as a small external image of the building model 300, for example, at an upper corner of one end of the wall surface 12 or 13 where it is easily visible to an observer.

[0042] When projecting images of three-dimensional views or cross sections of the building model 300, the image data projected onto the floor surface 11, wall surface 12, and wall surface 13 by the three projection devices 21, 22, and 23 are synchronized.

[0043] The partitioned space projection system 100 of the present invention can also place an actual component F, such as furniture, in a predetermined position, create three-dimensional view data of the component model 500 in place, and project images corresponding to the plan view, front view, and side view of the component model 500 onto the floor 11, wall 12, and wall 13 of the partitioned space 10.

[0044] Furthermore, it is also possible to form a so-called mixed reality (MR) space in which a real component F such as furniture is placed in a predetermined position, and images corresponding to the plan view, front view, and side view of the component model 500 are projected onto the floor 11, wall 12, and wall 13 of the partitioned space 10, and a virtual object G is superimposed and displayed within the partitioned space 10.

[0045] In this case, the mixed reality space formation program 600 and three-dimensional model data 510 of a component model 500 corresponding to a component F such as furniture are stored in the auxiliary storage device (hard disk) 44, and this can be realized by using MR goggles 70 and a controller 71 as shown in FIG. 10, and a tracker 75 and a base station 76 as shown in FIG. 11.

[0046] Here, as shown in FIG. 12, an observer P wears MR goggles 70 on his / her head, holds a controller 71 in both hands, and operates and controls the controller 71 appropriately, thereby being able to observe a real structure F and a virtual object G, which is an image, superimposed through the MR goggles 70.

[0047] On the other hand, as shown in FIG. 12, if a tracker 75 is attached and fixed at an appropriate position on the actual component F, and two base stations 76, 76 are installed on the upper wall surface or the like at both ends of the diagonal line of the compartmented space 10, infrared rays or other light rays L will be irradiated from these base stations 76, 76, and the light rays will be received by a position and rotation angle detection sensor S built into the tracker 75.

[0048] As shown in FIG. 13, the tracker 75 transmits the detection data signal generated by the position and rotation angle detection sensor S built into the tracker 75 to the computer main body 40 via a receiving device 80 installed at an appropriate position in the compartmented space 10, whereby the computer main body 40 is supplied with position and rotation angle data of the structure F, and based on this, the position and tilt state of the structure F can be recognized and acquired.

[0049] From the position and tilt state data of this component F and the three-dimensional model data 510 of the component model 500, the position and tilt state of the component F are created as initial data in the computer main body 40.

[0050] Then, based on this initial data, three-dimensional view data is created, and images corresponding to the initial plan view, front view, and side view of the component model 500 are projected onto the floor 11, wall 12, and wall 13 of the partitioned space 10.

[0051] Next, when the observer P grasps the structure F within the partitioned space 10 and moves it to a predetermined position and tilt state, the tracker 75 transmits a detection data signal to the computer main body 40, as described above, and the position and tilt state data of the structure F are created as movement data in the computer main body 40 from the position and tilt state data of the structure F and the three-dimensional model data 510 of the structure model 500.

[0052] Then, based on this movement data, three-dimensional view data is created, and images corresponding to the plan view, front view, and side view of the component model 500 when it is moved are projected onto the floor 11, wall 12, and wall 13 of the partitioned space 10.

[0053] Here, an information processing step was executed by the virtual space creation program 600, and a mixed reality (MR) space was created based on the three-dimensional model data 560 of the component model 550 corresponding to the chair C as shown in FIG.

[0054] As shown in FIG. 14, images corresponding to cross-sectional views of a plan view 571, a front view 572, and a side view 573 of the component model 550 could be projected onto the floor 11, wall 12, and wall 13 of the partitioned space 10.

[0055] Here, from the viewpoint of a third person N, a chair C is placed in the partitioned space 10, and an observer P is observed standing upright, as shown in FIG. On the other hand, from the viewpoint of an observer P, a state in which a human H, which is a virtual object G, is seated on a chair C placed in the partitioned space 10 is observed, as shown in FIG.

[0056] As described above, according to the partitioned space projection system of the present invention, the external or internal structure of an object such as a building or furniture can be cut into appropriate cross sections, broken down into three-dimensional views, and projected onto the floor and wall surfaces.The object can also be projected at life-size or at an appropriate magnification.Furthermore, furniture and other components installed within a building can be broken down into three-dimensional views and recognized three-dimensionally from each side, allowing objects such as buildings and furniture to be recognized with a sense of reality, which can be of great use to designers or purchasers when designing or purchasing a building, or when selecting components such as furniture.

[0057] Furthermore, the partition space projection system of the present invention allows for three-dimensional recognition of furniture and other components placed within a building, and by forming a mixed reality (MR) space and moving the components appropriately, it is possible to simulate the optimal placement of the components, the state in which a person would be seated, etc., which can be of great help to buyers when selecting furniture and other components.
