<Embodiment 1>
1 is a system configuration diagram of a construction and inspection support device for a structure in a building according to Embodiment 1 of the present invention, FIG. 2 (a) is an image diagram of a stereoscopic image of the structure projected by the support device, FIG. 2 (b) is a diagram showing a worker wearing red / blue glasses or polarized glasses, FIG. 2 (c) is an enlarged view of the red / blue glasses, and FIG. 2 (d) is an enlarged view of the polarized glasses. FIG.

In the first embodiment, the following known technique (1) or (2) is used as an image projection technique.
(1) Three-dimensional image projection technology using red-blue method (anaglyph method) This three-dimensional image projection technology using red-blue method produces left and right images in two colors that are complementary to each other. Use color. When the image drawn in red and blue is viewed through a red and blue filter (for example, glasses with a red filter on the left and a blue filter on the right (red and blue glasses) when viewed from the front), the left eye Since only the blue image can be seen and only the red image can be seen with the right eye, the stereoscopic image can be recognized.
(2) Stereoscopic Image Projection Technology by Polarization Method (Polaroid Method) The stereoscopic image projection technology by this polarization method is a method that uses a polarization filter to separate left and right images. A polarizing filter is attached to both the image projection device (projector) and glasses (polarization glasses). The image projection device separates the left and right images by polarizing 90 degrees with the polarization filter, and the glasses use right and left through the polarization filter. Since different images enter the eyes, stereoscopic images can be recognized.

  As shown in FIGS. 1 and 2, the construction construction and inspection support device for a structure in the building of the first embodiment is an image projection device (projector) 1, a 3D image creation device 2, and a keyboard. An input device 3 and red / blue glasses (goggles) 4 or polarized glasses (goggles) 5 are provided. When projecting an image in a plant building 6 such as a power plant or a chemical plant, the image projection device 1, the 3D image creation device 2, and the input device 3 are, for example, a floor surface 10 in the building 6 as shown in FIG. The red / blue glasses 4 or the polarized glasses 5 are attached to the eyes of the operator 11 as shown in FIG. As shown in FIG. 2C, the red / blue glasses 4 are provided with a red filter 12 on the left and a blue filter 13 on the right as viewed from the front. As shown in FIG. 2D, the polarizing glasses 5 are provided with a vertical polarizing filter 14 on the left and a horizontal polarizing filter 15 on the right as viewed from the front.

  The input device 3 is a keyboard connected to the 3D image creation device 2 which is a personal computer, and the building number (information for identifying the building when there are multiple buildings in the plant) with respect to the 3D image creation device 2 In addition to inputting the viewpoint position information of the worker (observer) in the building, etc., information related to construction work and inspection such as the scheduled construction date and work content is also input (information input means). The input device 3 is not limited to a keyboard, and a mouse, a light pen, or the like can be used.

  The 3D image creation device 2 has a 3D image creation function (software stored in a storage unit such as a hard disk) for a red-blue system or a polarization system, and in the building 6 stored in advance in the storage unit. Structures such as pipes and electric wires, pipes embedded in the wall of the building 6, structures such as reinforcing bars and electric wires (buried objects), and pipes constructed in the next building (room) It has 3D-CAD (three dimensions-computer aided design) data 9 such as a structure. When the red / blue method is employed, the 3D image creation apparatus 2 (will be seen) when viewed from the viewpoint position based on the viewpoint position information of the operator (observer) from the input apparatus 3. An image drawn in red and blue of the structure, which is a 3D image for the structure in red and blue, is created from the 3D-CAD data 9, and a signal of the 3D image is transmitted to the image projector 1. Further, when the polarization method is adopted, the 3D image creation apparatus 2 is based on the viewpoint position information of the operator (observer) from the input apparatus 3 and is viewed from the viewpoint position (will be visible). The left and right images of the structure, which are 3D images for the polarization method of the structure, are created from the 3D-CAD data 9, and signals of the 3D image are transmitted to the image projection apparatus 1.

  In addition, the 3D images of the structures for the red and blue systems and the polarization system are, at the time of construction, structures to be provided in the building 6 from now on, structures embedded in the wall surface, and adjacent structures. It is an image of a structure in a building (room) or the like, and is an image of a structure under construction or constructed in the building 6 at the time of inspection.

  In the image projection apparatus 1, when a 3D image signal for red-blue system or polarization system transmitted from the 3D image creation apparatus 2 is input, this 3D image is projected onto an image display unit 16 such as a wall surface in the building 6 ( indicate. That is, when the red-blue system is adopted, an image projection apparatus 1 for the red-blue system is used, and the image of the structure drawn in red and blue by the image projection apparatus 1 is displayed on the image display unit 16. Project. When the polarization method is adopted, the image projection device 1 is used for a polarization method in which a vertical polarization filter and a horizontal polarization filter are attached, and the image projection device 1 allows right and left images of the structure to be obtained. Each of the images is projected onto the image display unit 16 through the vertical polarizing filter and the horizontal polarizing filter.

  In the case of the red / blue system, the worker 11 wearing the red / blue glasses 4 views the image of the red and blue structure projected on the image display unit 16 through the red / blue glasses 4. Thus, a stereoscopic image of the structure can be seen. In the case of the polarization method, the operator 11 wearing the polarizing glasses 5 views the left and right images of the structure projected on the image display unit 16 through the polarizing glasses 5, thereby 3D images can be seen. That is, at the time of construction, a three-dimensional image of a structure (piping, electric wire, etc.) to be constructed in the building 6 can be seen along with the wall surface in the building 6 at the planned construction position of the structure. A three-dimensional image of a structure (piping, reinforcing bar, electric wire, etc.) embedded in the building and a structure (piping, etc.) built in the next room can be seen along with the wall surface at the burying position or construction position of the structure. Further, at the time of inspection, a stereoscopic image of a structure (pipe, electric wire, etc.) under construction or constructed in the building 6 appears to overlap the actual structure.

  At this time, if information related to construction work or inspection (scheduled construction date, work content, etc.) is input from the input device 3 to the 3D image creation device 2, the 3D image creation device 2 uses the information for the red-blue system. Or it writes in the 3D image of the structure for polarization systems, and transmits the 3D image to the image projection apparatus 1, and the image projection apparatus 1 projects the information together with the 3D image of the structure onto the image display unit 16. Therefore, the worker 11 can see the information together with the stereoscopic image of the structure through the red / blue glasses 4 or the polarized glasses 5.

  FIG. 2A shows an example of a stereoscopic image. 2A illustrates the case of a pipe and an electric wire as an example of the structure, and illustrates the case of the wall surface 8 in the building 6 as an example of the image display unit 16. As shown in FIG. 2A, the image projector 1 is installed at a predetermined position in the building 6 in a state of facing the wall surface 8. Then, the image projection device 1 projects a 3D image of the piping and wires for red and blue systems or polarization systems of the piping and wires to be constructed in the building 6 on the wall surface 8, and this projection image is projected on the building 6. When the worker 11 standing at a predetermined position in the image is viewed through the red / blue glasses 4 or the polarized glasses 5, the worker 11 can see the stereoscopic image of the pipe 17 and the electric wire 18 as shown in FIG. However, it can be seen along with the wall surface in the building 6 at these planned construction positions.

  At this time, when another worker 11 operates the input device 3 and inputs, for example, a construction date and work content as information related to the construction work of the pipe 17 and the electric wire 18, the 3D image creation device 2 The planned construction date and the work content are written in a 3D image for red / blue system or polarization system, and the 3D image is transmitted to the image projection apparatus 1. The planned construction date and work contents are also projected. As a result, the worker 11 can confirm the scheduled construction date and the work contents together with the stereoscopic images of the pipe 17 and the electric wire 18 through the red / blue glasses 4 or the polarized glasses 5.

  As described above, according to the construction or inspection support device for a structure in the building of the first embodiment, the 3D image creation device 2, the image projection device 1, the red-blue glasses 4 or the By having the polarizing glasses 5, a structure to be built in the building 6, a buried object embedded in the wall surface of the building 6, or a three-dimensional structure of a structure built in the adjacent building in the building 6 Since the video is displayed in the building 6, the worker 11 can create a construction plan, a process, and the like while viewing the stereoscopic video on the site.

  Further, for example, as shown in FIG. 2, the positional relationship between the duct hole 19 to be provided in the wall surface 8 and the piping 17 to be passed through the duct hole 19 is confirmed, the duct hole 19 and the buried object, It is also possible to easily and reliably check the positional relationship (whether or not to interfere) with the structure in the adjacent building. Furthermore, since the stereoscopic image of the structure built in the building 6 can be displayed on the building 6 so as to overlap the actual image of the structure, the worker 11 can actually display the stereoscopic image of the structure on the site. It is also possible to check the structure by comparing it with the actual structure of the structure easily and reliably.

  Further, since information related to construction or inspection of the structure can be displayed together with the stereoscopic image of the structure, the worker 11 confirms the information (scheduled construction date, work content, etc.) together with the stereoscopic image of the structure. It can be performed easily and reliably, and construction work or inspection work can be performed reliably.

<Embodiment 2>

  In the second embodiment, a known three-dimensional image projection technique using an alternate screening method (anaglyph method) is used as an image projection technique. This alternate-screening 3D image projection technique utilizes the afterimage effect of the human eye, and alternately projects left and right images onto the screen in a time-sharing manner. By viewing the projected image with glasses with an electronic shutter that opens and closes in synchronization with the shutter of the image projection device (projector), the left and right images can be viewed separately with the left and right eyes. Can be recognized.

  As shown in FIGS. 3 and 4, the construction and inspection support device for a structure in the building according to the second embodiment includes an image projection device 21 including two projectors 21 </ b> A and 21 </ b> B, and a 3D image creation device. 22, an input device 23 that is a keyboard, alternating shutter glasses 24, and a signal synchronization device 27. When projecting an image in a plant building 6 such as a power plant or a chemical plant, the image projection device 21, the 3D image creation device 22, and the input device 23 are, for example, a floor surface 10 in the building 6 as shown in FIG. The alternate shutter glasses 24 are attached to the eyes of the worker 11 as shown in FIG. As shown in FIG. 4C, the alternate shutter glasses 24 have electronic shutters 31 and 32 attached to the left and right. FIG. 4C illustrates a state when the electronic shutter 31 is opened and the electronic shutter 32 is closed.

  The input device 23 is a keyboard connected to a 3D image creation device 22 that is a personal computer. The 3D image creation device 22 has a building number (information for identifying a building when there are multiple buildings in the plant). In addition to inputting the viewpoint position information of the operator (observer), etc., information related to construction work and inspection such as the scheduled construction date and work content is also input (information input means). Note that the input device 23 to the 3D image creation device 22 is not limited to a keyboard, and a mouse, a light pen, or the like can also be used.

  The 3D image creation device 22 has a 3D image creation function (software stored in a storage unit such as a hard disk) for an alternate screening method, and piping, electric wires, etc. in the building 6 stored in advance in the storage unit And other structures such as pipes embedded in the wall surface of the building 6, structures such as reinforcing bars and electric wires (embedded objects), and pipes constructed in the next building (room) 3D-CAD data 9 is included. Then, the 3D image creation apparatus 22 uses the viewpoint position information of the operator (observer) from the input apparatus 3 to perform 3D for the alternate screening method of the structure when viewed from the viewpoint position (will be visible). The left and right images of the structure, which are images, are created from the 3D-CAD data 9 and a signal of the 3D image is transmitted to the image projection device 21. The 3D image of the structure for the alternate screening method is an image of the structure to be provided in the building 6 at the time of construction, or a structure embedded in the wall surface or an adjacent building ( It is an image of the structure of the room) and is an image of the structure under construction or constructed in the building 6 at the time of inspection.

  The image projection device 21 includes shutters on the left and right projectors 21A and 21B. When the left and right image signals, which are 3D images for the alternate screening method transmitted from the 3D image creation device 22, are input. These images are alternately projected in time division on the image display unit 16 such as a wall surface in the building 6 by alternately opening and closing the left and right shutters. At this time, in the signal synchronizer 27, the shutters of the two projectors 21A and 21B are alternately opened and closed (that is, the left and right images are alternately projected in time division), and the electronic shutters 31 and 32 of the alternate shutter glasses 24 are switched. Synchronize alternate opening and closing operations.

  Therefore, the worker 11 wearing the alternate shutter glasses 24 views the left and right images of the structure alternately projected on the image display unit 16 through the alternate shutter glasses 24, thereby enabling the stereoscopic video of the structure to be viewed. Can be seen. That is, at the time of construction, a three-dimensional image of a structure (piping, electric wire, etc.) to be constructed in the building 6 can be seen along with the wall surface in the building 6 at the planned construction position of the structure.

FIG. 9 is a system configuration diagram of a construction work and inspection support device for a structure in a building according to Embodiment 5 of the present invention, and FIG. 10 is an image diagram of a stereoscopic image of the structure projected by the support device.

  In the fifth embodiment, a known holography technique is used as an image projection technique. The outline of this technique will be described. First, a laser beam is applied to an object, and the scattered light (object beam) and another laser beam (reference beam) are simultaneously applied to a photographic plate to record interference fringes (hologram creation). When reproducing an image, laser light (reproduction light) is applied to a developed photographic dry plate, and diffracted light due to interference fringes is observed (hologram reproduction). Since both the intensity and the phase of the object light are recorded in the interference fringes, it is possible to reproduce a stereoscopic image. Holography is a hologram manufacturing technique, and a hologram is a photograph in which a three-dimensional image is recorded.

  As shown in FIG. 1, in the construction and inspection support device for a structure in a building according to the fifth embodiment, a laser oscillator 81, a mirror 82, and a photographic plate 83 are used when creating a hologram ( Hologram creation means) When performing hologram reproduction, a laser oscillator 84 and a developed photographic plate 83 are used (hologram reproduction means). The laser oscillation device 81 and the laser oscillation device 84 may be shared.

  First, when creating a hologram, the first laser beam output from the laser oscillation device 81 is applied (irradiated) to the recording object 85 in the plant building 6 such as a power plant or a chemical plant. ), The scattered light (object light) of the first laser light and the second laser light (reference light) output from the laser oscillation device 81 and reflected by the mirror 82 are simultaneously applied to the photographic dry plate 83, whereby the photographic dry plate The interference fringes are recorded at 83. In the interference fringes, both the intensity and phase of the object light are recorded. The recording target 85 is constructed in the building 6 under construction or in a structure such as a pipe or electric wire, or a buried object such as a reinforcing bar or electric wire before being embedded in a wall surface, or in an adjacent building (room). And the like. In addition, when creating a hologram of a structure (pipe, electric wire, etc.) to be built in the building 11 from these, a model of the structure (pipe, electric wire, etc.) is used as the recording object 85. The model of the structure can be created not only by hand, but also by a three-dimensional printer based on the 3D-CAD data of the structure.

  Next, when reproducing the hologram, a developed photographic plate 83 (hologram) is installed in the building 6 in front of the virtual image display section 87 such as a wall surface in the building 6, and laser oscillation is applied to the photographic plate 83. The laser beam (reproduction light) output from the device 84 is applied. As a result, diffracted light due to interference fringes on the photographic plate 83 is observed (a three-dimensional image of the recording object 85 is reproduced). That is, at the time of construction, a three-dimensional image of a structure (piping, electric wire, etc.) to be constructed in the building 6 can be seen along with the wall surface in the building 6 at the planned construction position of the structure. A three-dimensional image of a structure (piping, reinforcing bar, electric wire, etc.) buried in the room or a structure built in the next room can be seen along with the wall surface at the buried position or construction position of the structure. Further, at the time of inspection, a stereoscopic image of a structure (pipe, electric wire, etc.) under construction or constructed in the building 6 appears to overlap the actual object of the structure.

  In addition, a photographic plate (hologram) of information related to construction work and inspection (scheduled construction date, work content, etc.) is created in the same manner as the above-mentioned hologram creation of the structure, and this photographic plate is also placed on the photographic plate 8 in an overlapping manner. For example, when laser light (reproducing light) is applied to these photographic plates, the information can be confirmed together with the stereoscopic image of the structure.

  FIG. 10 shows an example of a stereoscopic image. In FIG. 10, the case of a pipe and an electric wire is illustrated as an example of the structure, and the case of the wall surface 8 in the building 6 is illustrated as an example of the virtual image display unit 87. As shown in FIG. 10, a photographic dry plate 83 (hologram) created using a pipe and electric wire model is installed at a predetermined position in front of the wall surface 8. Then, when laser light (reproduction light) is applied to the photographic dry plate 83 from the laser oscillation device 84, the stereoscopic image of the pipe 17 and the electric wire 18 is displayed to the worker 11 on the wall surface in the building 6 at these planned construction positions. It looks with. At this time, if a photographic dry plate (hologram) of the planned construction date and work content is also placed on the photographic dry plate 83, the worker 11 confirms the planned construction date and the work content together with the stereoscopic images of the piping 17 and the electric wires 18. can do.

  As described above, according to the construction or inspection support device for a structure in the building of the fifth embodiment, the photographic plate 83 and the laser oscillation device 82 serve as the image display means (hologram creation means and hologram reproduction means). , 84, a three-dimensional image of a structure to be built in the building 6, a buried object embedded in the wall surface of the building 6, or a structure built in the adjacent building in the building 6 Therefore, the worker 11 can create a construction plan, a process, and the like while viewing the stereoscopic image on the site.

  Further, for example, as shown in FIG. 10, the positional relationship between the duct hole 19 to be provided in the wall surface 8 and the piping 17 to be passed through the duct hole 19 is confirmed, the duct hole 19 and the buried object, It is also possible to easily and reliably check the positional relationship (whether or not to interfere) with the structure in the adjacent building. Furthermore, since the stereoscopic image of the structure built in the building 6 can be displayed on the building 6 so as to overlap the actual image of the structure, the worker 11 can actually display the stereoscopic image of the structure on the site. It is also possible to check the structure by comparing it with the actual structure of the structure easily and reliably.

  Further, since information related to construction or inspection of the structure can be displayed together with the stereoscopic image of the structure, the worker 11 confirms the information (scheduled construction date, work content, etc.) together with the stereoscopic image of the structure. It can be performed easily and reliably, and construction work or inspection work can be performed reliably.

  In the case of using the holographic technique, a transmissive display such as a transmissive liquid crystal display can be used instead of the photographic dry plate. In this case, piping or electric wires when viewed from the viewpoint position based on the viewpoint position information of the operator (observer) input to the computer from an input device such as a keyboard by a computer. A hologram image of the structure is created from 3D-CAD data (hologram creation means), and this hologram image is displayed on a transmissive display installed in front of the virtual image display unit. Then, laser light (reproduction light) is applied from the laser oscillation device to the hologram image displayed on the transmission display (hologram reproduction means). As a result, the operator can view a three-dimensional image of the structure as in the case of the photographic plate. In this case, if information related to construction work or inspection (scheduled construction date, work content, etc.) is input from the input device, this information is also written in the hologram image. In addition, the information can also be confirmed.
