Description

[Technical field]

[0001] The present invention relates to a method for recording an adjustment range and a method for performing an adjustment range recording. [Background technology]

[0002] For example, when tiling an exterior wall, construction records are created and kept. In addition, as construction records, the adjustment range (also called repair range) where a base adjustment coating material is applied to the base concrete is recorded. Conventionally, workers would visually observe the adjustment area and sketch it by hand, or take a photograph of the adjustment area, and then record the position and range of the adjustment area based on the sketch or photograph.

[0003] In relation to recording the position and range of adjustment points, Patent Document 1 describes that when recording the diagnosis results of exterior wall tiles, an image of the wall surface on which diagnosis result information (e.g., discrimination symbols written in chalk) by a worker is photographed, and the position of the diagnosis result information is recorded by analyzing the photographed wall image.

[0004] [Patent Document 1] JP 2014-134470 A Summary of the Invention [Problem to be solved by the invention]

[0005] According to Patent Document 1, when an inspector diagnoses a diagnosis target part on a wall, it is possible to reduce the workload of the inspector. However, for example, when recording the adjustment range adjusted based on the diagnosis, the worker still needs to sketch or photograph the adjustment part and manually record the position and range of the adjustment part on the elevation drawing. For this reason, there has been a demand for reducing the workload when recording the adjustment range.

[0006] Some embodiments of the present invention aim to reduce the workload when recording adjustment ranges of the exterior walls of a structure. [Means for solving the problem]

[0007] Some embodiments of the present invention are Extracting the adjustment range a display step of displaying an image of an elevation view of the wall surface on a display device; an allocating step of allocating the image of the wall surface taken by the camera device onto the image of the elevation view; and a recording step of identifying an area where the material is used from the image of the wall surface taken by the camera device and recording an adjustment range of the wall surface based on the identified area. The adjustment range includes a portion where the base adjustment coating material has been applied and a portion where the base adjustment coating material will be applied, and in the recording step, the adjustment range indicating the color of the base adjustment coating material is extracted by performing a binarization process on the image data based on a difference in saturation between the base and the base adjustment coating material. It is.

[0008] Other features of the present invention will become apparent from the following specification and drawings. Effect of the Invention

[0011] At least the following points will become apparent from the following specification and drawings.

[0012] A method for recording an adjustment range is disclosed that includes a photographing step of photographing a concrete wall surface on which a material for base adjustment has been used using a photographing device, a display step of displaying an image of an elevation view of the wall surface on a display device, an allocating step of allocating the image of the wall surface photographed by the photographing device on the image of the elevation view, and a recording step of identifying an area in which the material is used from the image of the wall surface photographed by the photographing device and recording an adjustment range of the wall surface based on the identified area. According to such a method for recording an adjustment range, the workload when recording the adjustment range of an exterior wall of a structure can be reduced.

[0013] The imaging device is preferably a 360-degree camera, which allows a wide imaging range to be secured even on a narrow platform.

[0014] In the recording step, it is preferable to record a record drawing in which an image of the adjustment range is allocated on an image of the elevation drawing, thereby reducing the workload when recording the adjustment range of the exterior wall of the structure.

[0015] In the recording step, it is preferable to calculate an area of ​​the adjustment range, which can reduce the workload when recording the adjustment range of the outer wall of the structure.

[0016] In the recording step, it is preferable to set a reference length in the elevation view, and calculate the area of ​​the adjustment range based on the reference length, the scale ratio of the image of the wall surface assigned to the image of the elevation view, and the number of pixels of the area of ​​the image of the wall surface corresponding to the adjustment range. This can reduce the workload when recording the adjustment range of the outer wall of a structure.

[0017] The material is preferably an organic base adjustment coating material containing a chromatic color pigment, and in the recording step, the adjustment range is preferably determined by extracting the area to which the base adjustment coating material is applied from the image of the wall surface taken by the photographing device. This can improve the accuracy of recording the adjustment range.

[0018] In the adjustment work step, the material is a chromatic tape that is applied to the wall surface so as to surround the portion of the wall surface to be adjusted, and in the recording step, it is preferable that the area of ​​the tape is identified from the image of the wall surface photographed by the photographing device, and the area surrounded by the area of ​​the tape is set as the adjustment range. This makes it possible to improve the accuracy of recording the adjustment range.

[0019] A construction method is disclosed that includes a base preparation step of preparing the base of a concrete wall surface using a material for preparation of the base, and a tiling step of laying tiles on the wall surface after the base preparation step, and includes a photographing step of photographing the wall surface using a photographing device, a display step of displaying an image of an elevation view of the wall surface on a display device, an allocating step of allocating the image of the wall surface photographed by the photographing device on the image of the elevation view, and a recording step of identifying an area where the material is used from the image of the wall surface photographed by the photographing device and recording an adjustment range of the wall surface based on the identified area. According to such a construction method, the workload when recording the adjustment range of the exterior wall of a structure can be reduced.

[0020] ===First embodiment=== <Exterior wall tiling installation method> FIG. 1 is a flow diagram of an exterior wall tiling construction method according to the first embodiment.

[0021] First, the concrete wall surface is inspected (S001). In this inspection, the surface condition of the base is confirmed and any areas that require adjustment (areas to be adjusted) are identified. In addition, pre-processing such as cleaning is performed on the surface of the base as necessary.

[0022] Next, the base is adjusted in the area where the base needs to be adjusted (S002). In the following description, the range in which the base is adjusted may be called the "adjustment range." The "adjustment range" includes both the area where the base adjustment coating material has been applied (see particularly the first embodiment) and the area where the base adjustment coating material will be applied (see particularly the second embodiment). The base adjustment may be called "repair," and the "adjustment range" may be called the "repair range." In this embodiment, when the base is adjusted (S002), the adjustment range is recorded. The method of recording the adjustment range will be described later.

[0023] After the base is adjusted (S002), tiles are laid on the concrete wall surface (S003). In this embodiment, after the tiles are laid, the joints are filled (S004). The joint filling involves filling the gaps between the tiles with joint material.

[0024] <How to record the adjustment range> · Adjustment Record System 100 2 is an explanatory diagram of the hardware configuration of the adjustment and recording system 100 of the first embodiment. In the following, the adjustment and recording system 100 used to realize each process (various processes in FIG. 5 and the like to be described later) performed in recording the adjustment range described above (adjusting the base: S002) will be described.

[0025] The adjustment and recording system 100 includes an imaging device 1 and an adjustment and recording device 10 .

[0026] The photographing device 1 is a device (camera) for photographing a concrete wall surface. The photographing device 1 of this embodiment is a so-called 360-degree camera. However, the photographing device 1 is not limited to a 360-degree camera, and may be, for example, a camera equipped with a fisheye lens or a semi-spherical camera.

[0027] When recording the adjustment range, a worker may photograph the wall surface from a narrow scaffold (see FIG. 6A and FIG. 6B described later). When a worker photographs the wall surface from a narrow scaffold, the distance between the wall surface and the photographing device 1 becomes narrow. In the case of a camera with a narrower angle of view than the 360-degree camera of this embodiment, it is necessary to photograph the wall surface from an oblique angle or to take multiple photographs while moving the scaffold laterally. However, in this embodiment, by using a 360-degree camera as the photographing device 1, a wide photographing range can be secured even on a narrow scaffold. This makes it possible to photograph the wall surface from the front even on a narrow scaffold. Therefore, in this embodiment, by using a 360-degree camera as the photographing device 1, the wall surface can be easily photographed, and the workload in the photographing work when recording the adjustment range of the outer wall of the structure can be reduced.

[0028] 3A and 3B are perspective views of the photographing device 1 constituting the adjustment and recording system 100 of the first embodiment. The 360-degree camera (photographing device 1) of this embodiment is configured with a plate-shaped housing. FIG. 3A shows one side (front side) of the housing of the photographing device 1, and FIG. 3B shows the other side (back side) of the housing of the photographing device 1. As shown in FIGS. 3A and 3B, the photographing device 1 is provided with wide-angle lenses 2 on both the front and back sides. This allows the photographing device 1 to photograph in all directions, up, down, left, and right, at once. However, the photographing device 1 may have a lens 2 arrangement and configuration other than those shown in FIGS. 3A and 3B.

[0029] The adjustment and recording device 10 is configured by a computer such as a personal computer or a server. The adjustment and recording device 10 may be configured by one computer or multiple computers. The adjustment and recording device 10 (computer) has a CPU 11 and a storage device 12. The CPU 11 is an arithmetic processing device that controls the adjustment and recording device 10. The storage device 12 is a main storage device such as a RAM or an auxiliary storage device such as a hard disk drive or an SSD (Solid State Drive). The storage device 12 stores programs, data, and the like. The CPU 11 reads and executes the programs stored in the storage device 12 to perform various processes described below. The adjustment and recording device 10 also includes a display device 13 (e.g., a display) and an input device 14 (e.g., a keyboard, a mouse). The adjustment and recording device 10 also includes a communication device 15, and is capable of acquiring image data from the photographing device 1 via the communication device 15.

[0030] FIG. 4 is a functional block diagram of the adjustment and recording device 10 constituting the adjustment and recording system 100 of the first embodiment.

[0031] The adjustment and recording device 10 includes a control unit 20 and a data storage unit 30.

[0032] The control unit 20 controls various processes to be performed by the adjustment and recording device 10. The control unit 20 is realized by the CPU 11 executing a control program stored in the storage device 12 to perform various controls. The control unit 20 has an image acquisition unit 21, an image processing unit 22, an allocation processing unit 23, and an adjustment and recording unit 24. Each function will be described later.

[0033] The data storage unit 30 is a storage unit for storing predetermined data. The various data stored in the data storage unit 30 will be described later.

[0034] · Procedure for recording adjustment range 5 is a flow diagram of the adjustment range recording method of the first embodiment. Each process in the diagram (each process of S103 to S107 in the first embodiment) is executed by CPU 11 reading and executing an adjustment and recording program stored in storage device 12 of adjustment and recording device 10.

[0035] In the method for recording the adjustment range of this embodiment, first, a base adjustment coating material is applied to the area of ​​the base to be adjusted (S101). After the base adjustment coating material is applied, an operator photographs the wall surface using the photographing device 1 (S102).

[0036] 6A and 6B are explanatory diagrams of how the wall surface 3 is photographed. Fig. 6A is an explanatory diagram of how the wall surface 3 is photographed as seen from the right to the left of the worker, and Fig. 6B is an explanatory diagram of how the wall surface 3 is photographed as seen from above the worker in a downward direction.

[0037] As shown in FIG. 6A and FIG. 6B, the worker photographs the wall surface 3 from above a narrow scaffold. For example, the height (dimension A) inside the scaffold is about 1700 mm, and the width (dimension B) inside the scaffold is, for example, 600 mm or 900 mm. The distance (dimension C) between the scaffold and the wall surface 3 is 500 mm or less, the photographing height (dimension D) is 800 to 1500 mm, and the distance (dimension E) between the wall surface 3 and the photographing device 1 is equal to or less than the sum (dimension B + dimension C) of the width inside the scaffold and the distance (dimension C) between the scaffold and the wall surface 3. Here, the worker photographs the wall surface 3 using a 360-degree camera as the photographing device 1 as described above, and can photograph at least a range of 1800 mm wide x 1800 mm high of the wall surface 3 in one photographing.

[0038] The photographed wall surface 3 includes the adjustment range where the above-mentioned base adjustment coating material is applied. In the first embodiment, as described later, the adjustment range is recorded based on the image data of the photographed wall surface 3.

[0039] In this embodiment, the worker continuously photographs the wall surface 3 multiple times while moving along the wall surface 3. Note that photographing the wall surface 3 multiple times also includes photographing a video while moving along the wall surface 3. The worker continuously photographs the wall surface 3 multiple times so that at least a portion of the wall surface 3 overlaps. Here, the worker photographs the video while moving along the wall surface 3. The video data includes multiple still images (frames) photographed so that at least a portion of the wall surface 3 overlaps. However, the continuous photographing of the wall surface 3 is not limited to photographing a video, and multiple still images may be photographed. Data (image data) of the image of the wall surface 3 photographed by the photographing device 1 is imported into the adjustment and recording device 10.

[0040] After photographing the wall surface 3 as described above (S102), image data of the wall surface 3 photographed by the photographing device 1 is imported into the adjustment and recording device 10 (S103). The image acquisition unit 21 of the adjustment and recording device 10 stores the image data stored in the photographing device 1 in the data storage unit 30 as original image data. The original image data includes a plurality of still images. Furthermore, at least some of the images of the wall surface 3 overlap among the plurality of still images included in the original image data.

[0041] Next, the image processing unit 22 of the adjustment recording device 10 performs image processing on the original image data to generate image data (processed image data) of one wall surface 3 (S104). Specifically, the image processing unit 22 performs distortion correction processing (e.g., wide-angle correction filter) on each of the multiple still images included in the original image, and then performs a combining process (e.g., mosaicing) to combine the multiple still images into one image using overlapping parts of the multiple distortion-corrected still images. As a result, data (processed image data) of a panoramic image of the horizontally long wall surface 3 is generated. In the following description, this panoramic image (processed image) of the wall surface 3 may be simply called a "processed image". Note that the process of S104 is not limited to performing the combining process after the distortion correction process. For example, the order of the distortion correction process and the combining process may be reversed, the distortion correction process and the combining process may be performed simultaneously, or other processes (e.g., trimming process, etc.) may be performed.

[0042] Next, the allocation processing unit 23 of the adjustment and recording device 10 reads out the elevation data stored in advance in the data storage unit 30, and displays the image of the elevation on the display device 13 (S105). Fig. 7 is an explanatory diagram of the image of the elevation displayed on the display device 13. The elevation includes an image of a drawing of the wall surface.

[0043] Next, the allocation processing unit 23 performs an allocation process for allocating the processed image to the elevation drawing (S106). Fig. 8 is a flow diagram of the allocation process of the processed image in S106. The allocation process of the processed image is executed by the CPU 11 reading and executing the adjustment record program stored in the storage device 12.

[0044] In the allocation process of the processed image, the allocation processing unit 23 reads out the processed image data created in S104 and displays the processed image by superimposing it on the image of the elevation (S201). FIG. 9 is an explanatory diagram of a state in which the size and position of the processed image superimposed on the image of the elevation is adjusted. However, at the stage of S201, the size and position of the wall surface shown in the elevation and the size and position of the wall surface 3 in the processed image data are in a state of mismatch. Therefore, as shown in FIG. 9, the worker operates the input device 14 (e.g., a mouse) of the adjustment recording device 10 to adjust the size and position of the processed image displayed on the display device 13 so that the processed image is aligned with the wall surface on the elevation displayed on the display device 13 (S202). In other words, the allocation processing unit 23 adjusts the size and position of the processed image in response to a signal from the input device 14 (S202). As a result, the processed image is allocated to a predetermined position on the image of the elevation.

[0045] Next, an adjustment range recording process is performed (S107). Fig. 10 is a flow diagram of the adjustment range recording process of S107. The adjustment range recording process is performed by the CPU 11 reading and executing an adjustment recording program stored in the storage device 12. In the adjustment range recording process, first, the allocation processing unit 23 performs an adjustment range extraction process (S301).

[0046] In the extraction process of the adjustment range in S301, the area where the material for adjusting the base is used is identified from the above-mentioned processed image. In this embodiment, the area where the base adjustment coating material is applied is extracted from the above-mentioned processed image.

[0047] Fig. 11A is an explanatory diagram of the state in which the organic base preparation coating material of the first embodiment is applied to the base. Fig. 11B is an explanatory diagram of the state in which the organic base preparation coating material of the same color as the base is applied to the base. Fig. 11C is an explanatory diagram of the binarized image of the wall surface of Fig. 11A.

[0048] In the first embodiment, an organic base preparation coating material is used as the base preparation coating material. The organic base preparation coating material is a base preparation coating material whose main component is a resin such as modified silicone resin. However, the resin constituting the main component is not limited to modified silicone resin, and may be other resins (e.g., urethane resin). The base preparation coating material of this embodiment contains a chromatic color pigment.

[0049] As shown in FIG. 11B, normal organic base preparation coating materials are configured to be the same color (gray or white) as the base concrete. The reason for making the base concrete and the base preparation coating material the same color (gray) is to make the base preparation coating material less noticeable even if the base preparation coating material is visible through the tile joints. For this reason, normal organic base preparation coating materials contain gray coloring pigments so that they are the same color (gray) as the base concrete. However, if the base concrete and the base preparation coating material are the same color (gray), the color difference between the base (concrete) and the base preparation coating material will be small, as shown in FIG. 11B.

[0050] In contrast, the organic base adjustment coating material of the first embodiment contains color pigments of chromatic colors such as red, blue, and yellow. As a result, when the base adjustment coating material is applied, the color difference between the base and the base adjustment coating material becomes large, as shown in FIG. 11A. Note that the organic base adjustment coating material of this embodiment does not contain gray color pigments in order to increase the color difference with the base. Since the organic base adjustment coating material of this embodiment does not contain gray color pigments, the saturation of the base adjustment coating material can be increased. In this embodiment, since the color difference between the base and the base adjustment coating material becomes large, the adjustment range can be extracted with high accuracy by performing binarization processing on the image of the wall surface (see FIG. 11C).

[0051] By the way, even if the lightness (or brightness) of the base adjustment coating material is made different (given a difference) with respect to the color of the base, it is possible to increase the color difference between the base and the base adjustment coating material. However, if only the lightness of the base adjustment coating material is different with respect to the color of the base, it may be difficult to distinguish the base and the base adjustment coating material based on the color difference in a situation where a shadow (for example, a shadow of scaffolding) is formed on the wall surface. In contrast, in the first embodiment, the difference in saturation (chroma difference) between the base and the base adjustment coating material is large. Therefore, in the first embodiment, even in a situation where a shadow (for example, a shadow of scaffolding) is formed on the wall surface, it is easy to distinguish the base and the base adjustment coating material by the chroma difference. Therefore, in the first embodiment, in order to increase the chroma difference with respect to the achromatic color (gray) of the concrete that serves as the base, a chromatic color pigment such as red, blue, or yellow is contained in the base adjustment coating material.

[0052] In the extraction process of the adjustment range (S301), specifically, the allocation processing unit 23 performs binarization processing on the processed image data so as to separate the area showing the color of the concrete base and the area showing the color of the base adjustment coating material in the processed image, and extracts the area showing the color of the base adjustment coating material. The area showing the color of the base adjustment coating material is the area where the base adjustment coating material is applied, that is, it corresponds to the adjustment range. In other words, the allocation processing unit 23 extracts the adjustment range of the wall surface 3 by extracting the area where the base adjustment coating material is applied from the image of the concrete wall surface 3. The allocation processing unit 23 may perform the extraction process of S301 before the allocation process of the processed image in S106. However, as in this embodiment, the extraction process of S301 is performed after the allocation process of the processed image in S106, making it easier to allocate the adjustment range on the elevation drawing.

[0053] In this embodiment, the concrete base is achromatic (gray), whereas the base adjustment coating material contains chromatic pigments, so that the area where the base adjustment coating material is applied is chromatic, such as red, blue, or yellow. As a result, the color difference between the base and the base adjustment coating material becomes large (see FIG. 11A), and in particular the saturation difference becomes large. Therefore, the allocation processing unit 23 of this embodiment performs binarization processing of the processed image data by calculating the saturation of each pixel of the processed image data and comparing the saturation of each pixel with a predetermined saturation threshold value. For example, by performing binarization processing on the image of the wall surface of FIG. 11A, the binarized image shown in FIG. 11C can be generated. In FIG. 11C, pixels with a saturation higher than the threshold value are shown in black, and pixels with a saturation lower than the threshold value are shown in white. As shown in FIG. 11C, the area with a saturation higher than the threshold value (area composed of black pixels) is the area showing the color of the base adjustment coating material, and shows the area where the base adjustment coating material is applied (adjustment range). In addition, in the binarization process, pixels with a saturation higher than the threshold value may be displayed in white, and pixels with a saturation lower than the threshold value may be displayed in black. In this way, in this embodiment, the area (adjustment range) showing the color of the base adjustment coating material can be extracted with high accuracy.

[0054] Note that the saturation difference between the base and the base-adjusting coating material in the image data is maintained large even if a shadow (for example, the shadow of scaffolding) is reflected in the image of the wall surface 3. Therefore, even if a shadow (for example, the shadow of scaffolding) is reflected in the image of the wall surface 3, the allocation processing unit 23 can perform binarization processing of the processed image data based on the saturation difference, thereby making it possible to extract with high accuracy the area (adjustment range) showing the color of the base-adjusting coating material.

[0055] In addition, image identification processing using AI may be performed during the extraction processing of S301. In this case, a large number of data in which an image of a wall surface coated with a base adjustment coating material and its adjustment range are associated are used as learning data, and a judgment model is generated in advance by machine learning using the learning data, in which an image of a wall surface coated with a base adjustment coating material is used as input data and the adjustment range is used as output data. Then, during the extraction processing of S301, the allocation processing unit 23 uses the above-mentioned processed image data as input data and determines the adjustment range corresponding to the processed image data based on the judgment model. In this way, the allocation processing unit 23 may extract the adjustment range by performing image identification processing using AI instead of binarization processing during the extraction processing of S301.

[0056] Next, the allocation processing unit 23 allocates the image of the adjustment range to a predetermined position on the image of the elevation by superimposing the extracted image of the adjustment range on the image of the elevation as shown in FIG. 12 (S302). The image of the adjustment range to be superimposed on the elevation may be the image of the adjustment range on the processed image data (color image before binarization), may be the image after binarization (image composed of black pixels), or may be an image with hatching applied to the area indicating the adjustment range. The allocation processing unit 23 repeats the processes of S201 to S202 and S301 to S302 as necessary. Here, the allocation processing unit 23 repeats the processes of S201 to S202 and S301 to S302 on the wall surface 3 of the first floor, and then repeats the processes of S201 to S202 and S301 to S302 on the wall surfaces 3 of the other floors. As a result, the image of the adjustment range is allocated to all the wall surfaces 3 of the construction target as shown in FIG. 13.

[0057] Finally, the adjustment recording unit 24 of the adjustment recording device 10 generates a record drawing of the adjustment range (S303). Here, the drawing data shown in Fig. 13 (drawing data in which an image of the adjustment range is assigned to an elevation drawing) is stored in the data storage unit 30 as a record drawing of the adjustment range (record drawing of the repair range). Note that, although there is no obligation to report the application area for organic base adjustment coating materials, the adjustment recording unit 24 may record the area of ​​the adjustment range as a record of the adjustment range, as described below.

[0058] 14A and 14B are diagrams illustrating a comparison of the operation time between the method for recording the adjustment range of the first embodiment and the method for recording the adjustment range of the comparative example.

[0059] In the comparative example, the worker makes a handwritten sketch while visually observing the adjustment area, and furthermore, the worker photographs the adjustment area, and records the position and range of the adjustment area based on the sketch and the photograph. In contrast, in the present embodiment, the adjustment area is photographed using a 360-degree camera (photographing device 1), and the adjustment range of the wall surface is recorded based on the area where the material for base adjustment (base adjustment coating material in the first embodiment) is used (area where the base adjustment coating material is applied in the first embodiment). This makes it possible to reduce the time required for handwriting in the comparative example (24 hours in this case), and also to reduce the time required for record creation (46.5 hours in this case). In other words, the workload when recording the adjustment range of the exterior wall of a structure can be reduced.

[0060] Fig. 15 is a flow diagram of the area calculation process for calculating the area of ​​the adjustment range. Fig. 16 is an explanatory diagram of the state of setting the reference length L on the elevation drawing. The area calculation process is executed by the CPU 11 reading and executing the adjustment recording program stored in the storage device 12.

[0061] The area calculation unit 24A sets the reference length L on the elevation drawing as shown in FIG. 16 (S401). Since various dimensions of the construction object are set in advance on the elevation drawing, the worker operates the input device 14 (e.g., a mouse) of the adjustment and recording device 10 to set a reference length (reference length) according to the dimension lines written on the elevation drawing, and sets a dimension (actual dimension) corresponding to the reference length. Here, as shown in FIG. 16, the reference length L is set along the horizontal direction of the wall surface, and an actual dimension (e.g., L=16000 mm) corresponding to the reference length L is set. Note that instead of the worker operating the input device 14 to set the reference length L, the area calculation unit 24A may set the reference length L by analyzing the image of the elevation drawing.

[0062] Next, the area calculation unit 24A specifies the scale ratio R of the processed image with respect to the elevation drawing (S402). Specifically, the area calculation unit 24A specifies the scale ratio R of the processed image with respect to the elevation drawing (the processed image after the adjustment in S202).

[0063] Next, the area calculation unit 24A specifies the size S1 of the adjustment range on the processed image (S403). For example, the area calculation unit 24A specifies the number of pixels in the area of ​​the adjustment range on the processed image (the area on the processed image where the base adjustment coating material is applied; the "high saturation area" in FIG. 11C) as the size S1 of the adjustment range on the processed image.

[0064] Next, the area calculation unit 24A calculates the actual area S2 of the adjustment range based on the reference length L, the scale ratio R, and the size S1 (S404). Specifically, since the area (unit: m2 or mm2) corresponding to one pixel on the processed image is determined based on the reference length L and the scale ratio R, the area calculation unit 24A calculates the actual area S2 (unit: m2 or mm2) of the adjustment range area based on the number of pixels (S1) of the adjustment range area on the processed image. Note that since there are usually multiple adjustment ranges, the area calculation unit 24A repeatedly performs the processes of S403 and S404 for each adjustment range.

[0065] Fig. 17 is an explanatory diagram of another example of a record diagram of the adjustment range. The adjustment record unit 24 assigns an identification number to each adjustment range and records the area of ​​each adjustment range in association with each other. The adjustment record unit 24 can assign an identification number to each adjustment range by, for example, performing a labeling process on the adjustment range on the processed image. The adjustment record unit 24 may record the area of ​​the adjustment range as shown in Fig. 17 as a record of the adjustment range.

[0066] ===Second embodiment=== <Exterior wall tiling installation method> FIG. 18 is a flow diagram of a method for recording the adjustment range according to the second embodiment.

[0067] In the second embodiment, a different adjustment range is recorded for the base adjustment (S002) shown in Fig. 1 from that in the first embodiment. Note that, apart from the base adjustment (S002), the procedure is the same as the procedure for tiling an exterior wall shown in Fig. 1.

[0068] In recording the adjustment range in the second embodiment, first, the worker applies masking tape to the base so as to surround the adjustment range (S501).

[0069] Fig. 19A is an explanatory diagram of a state in which an adjustment range is surrounded by masking tape of the present embodiment, and Fig. 19B is an explanatory diagram of a state in which an adjustment range is surrounded by masking tape of a similar color to the base.

[0070] As shown in Fig. 19B, in the case of transparent curing tape (or white curing tape), the curing tape will be the same color (gray; achromatic) as the underlying concrete. However, if the curing tape is the same color (gray) as the underlying concrete, the color difference between the underlying concrete and the curing tape will be small, as shown in Fig. 19B.

[0071] In contrast, the masking tape of the second embodiment is composed of a tape of a chromatic color, such as green or yellow. That is, the masking tape of the second embodiment is composed of a base material and an adhesive material, and the base material is composed of a chromatic member, such as green or yellow. This increases the color difference between the base material and the masking tape, as shown in FIG. 19A. In the second embodiment, since the color difference between the base material and the masking tape is large, it becomes possible to extract the adjustment range with high accuracy by performing a binarization process on the image of the wall surface (described later: see FIG. 19C).

[0072] Incidentally, even if the lightness (or luminance) of the masking tape is made different (given a difference) with respect to the color of the base, it is possible to increase the color difference between the base and the masking tape. However, if only the lightness of the masking tape is different with respect to the color of the base, it may be difficult to distinguish the base and the masking tape based on the color difference in a situation where a shadow (for example, a shadow of scaffolding) is formed on the wall surface. In contrast, in the second embodiment, the difference in saturation (chroma difference) between the base and the masking tape is large. Therefore, in the second embodiment, even in a situation where a shadow (for example, a shadow of scaffolding) is formed on the wall surface, it is easy to distinguish the base and the masking tape by the chroma difference. Therefore, in the second embodiment, a chromatic masking tape such as green or yellow is used to increase the chroma difference with respect to the achromatic color (gray) of the concrete base.

[0073] After surrounding the adjustment range with masking tape (S501), an operator photographs the wall surface using the photographing device 1 (e.g., a camera) (S502). The photographing process in S502 is similar to S102 in the first embodiment (see FIG. 5). However, in the case of the second embodiment, the photographed wall surface 3 includes the adjustment range surrounded by the masking tape described above. In the second embodiment, the wall surface 3 is photographed before the base adjustment material is applied to the adjustment range, and the adjustment range is recorded based on the image data of the wall surface 3 photographed at this time.

[0074] The configuration of the adjustment and recording system 100 of the second embodiment is similar to that of the first embodiment (see Figs. 2 to 4). Also in the second embodiment, similar to the first embodiment, the adjustment and recording device 10 executes each process in the figure (each process of S503 to S507 in the second embodiment) by the CPU 11 reading and executing the adjustment and recording program stored in the storage device 12. Also in the second embodiment, similar to the first embodiment, the adjustment and recording device 10 executes each process shown in Figs. 8 and 10 during the allocation process of S506 and the adjustment range recording process of S507.

[0075] In the second embodiment, similarly to the first embodiment, image data of the wall surface 3 photographed by the photographing device 1 is imported into the adjusting and recording device 10 (S503), image processing is performed on the original image data to generate one piece of image data of the wall surface 3 (processed image data) (S504), elevation data previously stored in the data storage unit 30 is read out, and an image of the elevation is displayed on the display device 13 (S505). Also in the second embodiment, similarly to the first embodiment, allocation processing is performed to allocate the processed image to the elevation (S506).

[0076] In the second embodiment, the allocation processing unit 23 also performs a recording process of the adjustment range (S507). In the recording process of the adjustment range in S507, similar to S301 in the first embodiment, the allocation processing unit 23 performs an extraction process of the adjustment range. In the extraction process of the adjustment range in the second embodiment, an area where a material for adjusting the base is used is identified from the processed image. In this embodiment, an area where masking tape is applied is identified from the above-mentioned processed image. Then, based on the area where masking tape is applied, it is extracted as the adjustment range of the wall surface 3.

[0077] In the second embodiment, the allocation processing unit 23 performs binarization processing on the processed image data so as to separate an area showing the color of the concrete base from an area showing the color of the masking tape in the image shown by the processed image data, and extracts an area showing the color of the masking tape. The area showing the color of the masking tape is an area where the masking tape is attached. Therefore, an area surrounded by an area showing the color of the masking tape (an area inside the area showing the color of the masking tape; a "low saturation area" inside the "high saturation area" in FIG. 19C) corresponds to an adjustment range. Therefore, the allocation processing unit 23 identifies an area showing the color of the masking tape from an image of the concrete wall surface 3, and extracts an area surrounded by the area showing the color of the masking tape as an adjustment range of the wall surface 3. Note that in the second embodiment, as in the first embodiment, the allocation processing unit 23 may perform the extraction processing before the allocation processing of the processed image in S506.

[0078] In the second embodiment, the concrete base is achromatic (gray), whereas the masking tape is chromatic, such as red, blue, or yellow. As a result, the color difference between the base and the masking tape becomes large (see FIG. 19A), and in particular the saturation difference becomes large. Therefore, the allocation processing unit 23 of the second embodiment performs binarization processing of the processed image data by calculating the saturation of each pixel of the processed image data and comparing the saturation of each pixel with a predetermined saturation threshold value. For example, by performing binarization processing on an image of the wall surface of FIG. 19A, a binarized image shown in FIG. 19C can be generated. In FIG. 19C, pixels with a saturation higher than the threshold value are shown in black, and pixels with a saturation lower than the threshold value are shown in white. As shown in FIG. 19C, the area with a saturation higher than the threshold value (area composed of black pixels) is an area showing the color of the masking tape, and the area inside that area (area composed of white pixels) shows the adjustment range. In the binarization process, pixels with saturation higher than the threshold value may be displayed in white, and pixels with saturation lower than the threshold value may be displayed in black. In this way, in the second embodiment, the adjustment range can be extracted with high accuracy.

[0079] In the second embodiment, the saturation difference between the base and the masking tape in the image data is maintained large even if a shadow (for example, the shadow of scaffolding) is reflected in the image of the wall surface 3. Therefore, even if a shadow (for example, the shadow of scaffolding) is reflected in the image of the wall surface 3, the allocation processing unit 23 performs binarization processing of the processed image data based on the saturation difference, so that the area showing the color of the masking tape can be accurately determined, and as a result, the adjustment range can be extracted with high accuracy.

[0080] Incidentally, after applying the base adjustment coating material to the wall surface 3, the wall surface 3 to which the base adjustment coating material has been applied is photographed, the photographed image is analyzed, and the processed image data is subjected to binarization processing so as to separate the area showing the color of the base concrete from the area showing the color of the base adjustment coating material, thereby extracting the adjustment range. However, when a cement-based base adjustment coating material is used as in the second embodiment, the color difference between the concrete and the base adjustment coating material is small, so it is difficult to perform binarization processing so as to separate the area showing the color of the base concrete from the area showing the color of the base adjustment coating material, and as a result, there is a risk of misrecognizing the adjustment range. In contrast, in the second embodiment, the masking tape is made of a chromatic color, and the color difference (especially the saturation difference) between the base and the masking tape is increased, so that the area showing the color of the masking tape can be accurately identified, and the adjustment range can be extracted with high accuracy.

[0081] In the second embodiment as well, the allocation processing unit 23 allocates the image of the adjustment range to a predetermined position on the image of the elevation by superimposing the extracted image of the adjustment range on the image of the elevation as shown in Fig. 12. Also in the second embodiment, the allocation processing unit 23 repeats the processes of S201 to S202 and S301 to S302 as necessary. As a result, in the second embodiment as well, the image of the adjustment range is allocated to all wall surfaces 3 of the construction target as shown in Fig. 12.

[0082] In the second embodiment, after the extraction process, the adjustment and recording unit 24 of the adjustment and recording device 10 generates a record diagram of the adjustment range. Then, the base adjustment coating material is applied to the area of ​​the base to be adjusted (S508).

[0083] In this embodiment, as in the first embodiment, a 360-degree camera (photographing device 1) is used to photograph the adjustment area, and the adjustment range of the wall surface is recorded based on the area where the material for base adjustment (base adjustment coating material in the first embodiment) is used (area where masking tape is applied in the second embodiment). This makes it possible to reduce the time required for handwriting in the comparative example described above, and also to shorten the time required for record creation. In other words, the workload when recording the adjustment range of the exterior wall of a structure can be reduced.

[0084] Also, in the second embodiment, similarly to the first embodiment, the adjustment record unit 24 may record the area of ​​the adjustment range as the record of the adjustment range (see Figs. 15 to 17). In the above-mentioned first embodiment, the area calculation unit 24A specified the number of pixels in the area of ​​the adjustment range on the processed image (the area on the processed image where the base adjustment coating material is applied; the "high saturation area" in Fig. 2C) as the size S1 of the adjustment range on the processed image (S403). In contrast, in the second embodiment, the area calculation unit 24A may specify the number of pixels in the area of ​​the adjustment range on the processed image (the area surrounded by the masking tape area on the processed image; the "low saturation area" inside the "high saturation area" in Fig. 19C) as the size S1 of the adjustment range on the processed image during the process of S403. And, in the second embodiment, similarly to the first embodiment, the area calculation unit 24A may calculate the actual area S2 of the adjustment range based on the reference length L, the scale ratio R, and the size S1 during the process of S403.

[0085] ===Summary=== In the above-mentioned embodiment (first to second embodiment), the following steps are performed: a photographing step (S102, S502) of photographing a concrete wall surface 3 using a photographing device 1 (for example, a 360-degree camera) on which a material for adjusting the base (for example, an organic base-adjusting coating material or a masking tape) is used; a display step (S105, S505) of displaying an image of an elevation of the wall surface 3 on a display device 13; an allocation step (S106, S506) of allocating the image of the wall surface 3 photographed by the photographing device 1 on the image of the elevation; and a recording step (S107, S507) of identifying an area where a material is used (for example, an area where a base-adjusting coating material is applied or an area where a masking tape is applied) from the image of the wall surface photographed by the photographing device 1 and recording the adjustment range of the wall surface 3 based on the identified area. In the above-mentioned embodiment, the time required for handwriting can be reduced when recording the adjustment range of the exterior wall of a structure. In addition, the time required for record creation can also be reduced when recording the adjustment range of the exterior wall of a structure. In other words, the workload when recording the adjustment range of the exterior wall of a structure can be reduced.
