Description

  The present invention relates to a damage diagram editing apparatus and a damage diagram editing method for editing a damage diagram illustrating a damage state of a structure, and more particularly to a damage diagram illustrating a damage state viewed from the side opposite to an imaging side of a structure. The present invention relates to a damage diagram editing apparatus and a damage diagram editing method that enable accurate and easy editing.

  Structures such as bridges and tunnels exist as social infrastructure. Since these structures are damaged, and the damage has the property of proceeding, regular inspections are required.

  The investigator who inspected the structure needs to prepare a check form in a predetermined format as a form indicating the result of the check, and there is a damage diagram illustrating the damage state of the structure as one of the check forms. By looking at the damage map created in the prescribed format, even if it is an expert who is different from the inspector who actually inspected, understand the progress of damage to the structure and formulate a maintenance plan for the structure. It becomes possible.

  Patent Document 1 discloses a CAD (computer aided design) drawing showing a building and an outside wall surface of the building when creating a figure (corresponding to the above “damage map”) showing a crack on the outer wall surface of the building. The captured image is displayed in a different display area of the computer device, and when a crack image in the displayed captured image is traced by the operation device, a trace diagram corresponding to the trace operation is mapped onto the CAD drawing. It is described.

  In Patent Document 2, when creating a development showing the uneven shape of the inner wall surface of the tunnel, an uneven shape figure is generated based on measurement data obtained by measuring the inner wall surface of the tunnel with a laser scanner, It is described that an image pattern is drawn on a concavo-convex figure. This development view can be created as a diagram showing the uneven shape when the inner wall surface is seen through the tunnel from above.

  As a predetermined type of damage diagram, it may be required to create a damage diagram illustrating a damage state viewed from the side opposite to the viewing side of the structure. For example, an investigator who visually inspects a floor deck of a bridge actually sketches the damaged state of the floor slab from the lower side of the bridge as a damaged state viewed from the upper side of the bridge. It is necessary to create a form of damage diagram.

  In addition, when the floor slab is imaged by an imaging device such as a digital camera instead of visual observation, according to the floor slab image obtained from the lower side of the bridge, the imaging side (the lower side of the bridge) and It is necessary to create a predetermined form of damage diagram to illustrate the state of damage as seen from the opposite side (above the bridge).

  However, since the shape and position of the damage look different when viewed from the bottom of the bridge and from the top of the opposite bridge, the load to create a damage diagram that accurately reflects the damage state It takes. For example, when creating a damage diagram illustrating the state of cracks, it is necessary not only to enter numerical values such as the width of cracks and the distance between cracks into the damage diagram, but also to accurately enter the shape and position of the cracks in the damage diagram. It is done. Here, when the actual crack state is not accurately reflected in the damage diagram, it is difficult to accurately grasp the progress of damage to the structure, and it is also difficult to formulate an appropriate maintenance management plan.

  According to the technique described in Patent Document 1, the investigator traces the crack image in the captured image displayed on the computer device, thereby mapping the trace diagram corresponding to the crack image on the CAD drawing. However, the damage state viewed from the opposite side to the imaging side of the structure cannot be mapped on the CAD drawing. In the first place, since the object to be inspected is the outer wall surface of the building in the embodiment of Patent Document 1, it is considered sufficient if it is possible to create a cracked view as seen from the imaging side (outside the building).

  According to the technique described in Patent Document 2, it is possible to create a developed view showing the uneven shape when the inner wall surface is seen through the tunnel from above the tunnel, but the uneven shape of the inner wall surface of the tunnel is measured with a laser scanner. If it is necessary and a laser scanner is not used, it is not possible to create a developed view showing the uneven shape of the inner wall surface when viewed from above the tunnel.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments for carrying out a damage diagram editing apparatus and a damage diagram editing method according to the present invention will be described with reference to the accompanying drawings.

[Example of structure]
FIG. 1 is a perspective view showing a structure of a bridge as an example of a structure to which the present invention is applied, and is a perspective view when the bridge is viewed from below. The bridge 1 in this figure has a main girder 2, a cross girder 3, an inclined frame 4, and a horizontal frame 5. On the upper part of the main girder 2, a floor slab 6 which is a concrete member is provided. The main girder 2 is a member that is passed between the abutment or the pier and supports the load on the floor slab 6. The cross beam 3 is a member for connecting the main beams 2 in order to support the load by the plurality of main beams 2. The anti-tilting structure 4 and the horizontal structure 5 are members that connect the main beam 2 in order to particularly resist lateral loads.

  The bridge 1 shown in FIG. 1 is an example of a structure introduced for use in the description of the present invention, and the “structure” in the present invention is not limited to such a bridge. The structure in the present invention may be a tunnel, for example.

[First Embodiment]
FIG. 2 is a block diagram illustrating a configuration example of the damage diagram editing apparatus according to the first embodiment.

  The imaging device 10 is configured by an imaging device that images a structure to be inspected. Examples of the imaging device include a digital camera and a smartphone. An imaging device other than these may be used.

  The damage diagram editing apparatus 20 includes a display unit 22 that can display an image, an operation unit 24 that receives a user's operation, and an image input unit 26 that inputs an image obtained by imaging the structure to be inspected by the imaging device 10. And a drawing input unit 28 for inputting a CAD (computer aided design) drawing showing the structure to be inspected, a CPU (central processing unit) 30 for executing the program, and a program and information necessary for executing the program are stored. Storage unit 50.

  The display unit 22 is configured by a display device such as a liquid crystal display device. The operation unit 24 can be configured with a keyboard and a mouse. The operation unit 24 may be configured by an operation device other than these, for example, a touch panel. The image input unit 26 and the drawing input unit 28 can be configured by an input device that inputs a digital signal. As such an input device, for example, a communication device that performs wireless communication or wired communication may be used. An interface device with a storage medium such as a memory card may be used as an input device. The CPU 30 may be composed of a plurality of CPUs. The storage unit 50 is configured by a memory device.

  The CPU 30 includes a display control unit 32 that controls the display unit 22, an image correction unit 34 that performs image correction, a mirror inversion unit 36 that mirrors and inverts an image to obtain a mirror image, and an image that performs image composition. The combination part 38, the damage detection part 40 which detects a damage image from a mirror image (or image before mirror reversal), and the damage figure which shows the damage state of a structure, Comprising: The damage figure corresponding to a mirror image And an editing unit 42 for editing the.

  The display control unit 32 causes the display unit 22 to display the mirror image superimposed on the CAD drawing. Further, the display control unit 32 causes the display unit 22 to display a mirror image and a damage diagram.

  The image correction unit 34 performs necessary image processing among enlargement / reduction, tilt correction, and rotation on the image. That is, the correction regarding the mismatch of the distance or the angle between the imaging target surface of the structure and the imaging device 10 over a plurality of divided images is performed. “Enlargement / reduction” in this example is a scale correction related to a mismatch in distance between the imaging apparatus 10 and the floor slab 6 (which is the imaging target surface) over a plurality of divided images. The image correction unit 34 in this example performs image processing for matching the scales of a plurality of images by enlarging or reducing the images. The “tilt correction” in this example is a correction related to the mismatch of the inclination angle of the floor slab 6 (which is the imaging surface) with respect to the imaging direction of the imaging apparatus 10 over a plurality of divided images. The image correction unit 34 in this example performs image processing for reducing or matching image distortion according to the inclination angle of the floor slab 6 with respect to the imaging direction. The “rotation” in this example is a correction related to a mismatch in the azimuth angle of the imaging apparatus 10 with respect to the floor slab 6 (which is the imaging target surface) over a plurality of divided images. The image correcting unit 34 in this example performs image processing for matching the angles of the floor slab 6 in the image between the plurality of images. Each correction parameter can be input from the operation unit 24. For example, the operation unit 24 receives inputs such as distance information, tilt angle information, and azimuth angle information. Correction parameters may be acquired from the imaging device 10. For example, the image correction unit 34 acquires coordinate values in the local coordinate system based on the imaging device 10, converts the coordinate values in the global coordinate system based on the bridge 1, and based on the coordinate values in the global coordinate system. Determine correction parameters. When correction parameters are added to the image, image correction may be performed using the correction parameters added to the image. Correction parameters may be derived based on the image. For example, it is possible to detect the edge of the case from the image, further calculate the shape, size, and angle of the edge region in the image based on the image, and derive the correction parameter based on the calculation result. When the above-described “enlargement / reduction”, “tilting correction”, and “rotation” are combined, it can be performed as a single image processing. As the image processing, a known projective transformation can be used.

  The mirror inversion unit 36 performs mirror inversion, which is image processing for converting the image input by the image input unit 26 into a mirror image. A “mirror image” is also referred to as a “mirror image”. “Mirror reversal” is also called “mirroring”. The direction of the axis serving as the center of mirror reversal (hereinafter referred to as “mirror reversal axis”) is not limited to the vertical direction of the image. That is, mirror reversal is not limited to so-called left-right reversal. The mirror inversion includes inversions other than left-right inversion (eg, upside-down inversion). The mirror reversal in the present invention can be said to be image processing for reversing an image around the mirror reversal axis. The direction of the mirror reversal axis can be determined, for example, by analyzing the input image. Further, the mirror inversion of the present invention includes an aspect in which the direction of the mirror inversion axis is fixed and an aspect in which the direction of the mirror inversion axis is variable. In the present specification, the latter variable direction mode will be described in detail later.

  Such mirror reversal will be described with reference to FIGS. As shown in FIG. 3, if the letter “F” drawn on the upper surface of the floor slab 6 is seen through from the lower side of the floor slab 6, it actually looks like a vertically inverted shape of “F”. This is because “F” has a non-axisymmetric shape. Similarly, since a general damage (for example, a crack) has a non-symmetrical shape, the shape of the damage in the image obtained by imaging the floor slab 6 from the lower side of the bridge 1 and the upper side of the bridge 1. Thus, it can be seen that the shape of the damage when seen through the floor slab 6 is in a mirror-inverted relationship with each other. Therefore, as shown in FIG. 4, an image IMG1 obtained by imaging from the lower side of the bridge 1 is converted into a mirrored image IMG2 corresponding to an image viewed from the upper side of the bridge 1 by mirror inversion. Then, the shape of the damage is from the shape when viewed from the lower side of the bridge 1 (the shape in which “F” is turned upside down in FIG. 4) to the shape viewed from the upper side of the bridge 1 (the shape of “F” in FIG. 4). ). It can be seen that the position of damage in the image can also be converted from the position seen from the imaging side to the position seen from the side opposite to the imaging side by mirror inversion. In addition, the case where divided imaging is performed a plurality of times will be described in detail later.

  In the example shown in FIG. 4, since the direction of the coordinate axis Gx of the global coordinate system with reference to the bridge 1 matches the left-right direction (x direction) of the image IMG1, the image IMG1 is inverted upside down as a mirror inversion. However, for example, when the direction of the coordinate axis Gx of the global coordinate system matches the vertical direction (y direction) of the image IMG1, the image IMG1 is reversed left and right as mirror reversal.

  When a plurality of images (hereinafter referred to as “divided images”) obtained by dividing and capturing the structure multiple times are input to the image input unit 26, the image composition unit 38 displays these divided images as one sheet. To the image. Such an image composition mode includes a first image composition mode for synthesizing a plurality of mirror-inverted divided images (which are mirror images), and a plurality of segmented images (non-mirror movie) before mirror inversion. A second image composition mode for synthesizing the image. Details of each synthesis mode will be described later.

  In the first image composition mode, the mirror inversion unit 36 mirrors and inverts each of the plurality of divided images. Further, in the first image composition mode, the display control unit 32 superimposes each of the mirror-inverted divided images on a region to be imaged in a CAD drawing showing a structure viewed from the side opposite to the imaging side. be able to. In the second image composition mode, the mirror reversing unit 36 mirror-inverts the composite image obtained by combining the plurality of divided images by the image composition unit 38. Further, in the second image composition mode, the display control unit 32 can superimpose each divided image before mirror reversal on an imaged area in a CAD drawing showing a structure viewed from the imaging side.

  The damage detection unit 40 detects a damaged image from a mirror image (or an image before mirror reversal). For example, an image of damage (damage image) such as cracks, peeling, rebar exposure, free lime, and water leakage is detected from the mirror image of the floor slab 6 of the bridge 1, and the detected damage image is extracted from the mirror image.

  The editing unit 42 has a damaged graphic generation function for generating a damaged graphic corresponding to the damaged image detected by the damage detection unit 40. The display control unit 32 causes the display unit 22 to display a damaged graphic corresponding to the detected damaged image on the damaged image in the mirror image. For example, damage figures such as cracks, peeling, reinforcing bar exposure, free lime, and water leakage shown in FIG. 5 are generated. The shape of each damaged figure corresponds to the shape of the damaged image in the mirror image. The editing unit 42 adds the generated damaged graphic to the damage diagram.

  Further, the editing unit 42 can generate a damaged graphic corresponding to the trace operation on the operation unit 24. The operation unit 24 receives a trace operation for a damaged image in the mirror image while the mirror image is displayed on the display unit 22. The display control unit 32 causes the display unit 22 to display the damaged figure corresponding to the trace operation on the damaged image in the mirror image. The editing unit 42 adds a damaged figure corresponding to the trace operation to the damage diagram. In addition to addition, it is preferable to accept various editing operations such as “deletion” and “correction”.

  In addition, the editing unit 42 adds various information input by the operation unit 24 to the damage diagram. The operation unit 24 receives input of inspection result information for damage in a state where a mirror image is displayed on the display unit 22. The display control unit 32 causes the display unit 22 to display the input inspection result information and the mirror image. The editing unit 42 adds the input inspection result information to the damage diagram. For example, when the type of damage and the evaluation category (also referred to as “rank information”) of the damage level are input from the operation unit 24, the damage is added to the damage diagram. The “input” of the inspection result information may be “selection input” that is an input in a format for selecting from predetermined candidates.

  The editing unit 42 has a feature amount measurement function for measuring a feature amount of damage based on a mirror image (or an image before mirror reversal). The editing unit 42 adds information indicating the measured feature amount to the damage diagram. For example, the width, length, and interval of the crack image in the mirror image of the floor slab 6 of the bridge 1 are detected as the dimensions of the local coordinate system, and the dimensions of the local coordinate system are converted into the dimensions of the global coordinate system. The display control unit 32 causes the display unit 22 to display the measured feature amount of damage and the mirror image.

  FIG. 6 is a diagram illustrating an example of a damage diagram. This damage diagram shows the damage figure that shows damage such as cracks, water leakage, and free lime, and the name of each member (in this example, “floor slab”) for each damage that occurred on the floor slab 6 of the bridge 1 to be inspected. ”), Element numbers (Ds0101 to Ds0104, Ds0201 to Ds0204), damage type (“ crack ”,“ water leakage ”,“ free lime ”, etc.), and damage evaluation grade (also referred to as“ rank information ”) And the characteristic amount of damage (for example, the width and interval of cracks). In this figure, the evaluation classification is represented by five alphabets “a” to “e” as the degree of damage.

  Further, the CPU 30 includes a damage diagram reversing unit 44 that reverses the damage diagram. FIG. 7 shows an example of an inversion damage diagram obtained by inverting the damage diagram shown in FIG. As shown in FIG. 7, the damage diagram inversion unit 44 of the present example shows the damage diagram of FIG. 6 showing the state of damage viewed from the side opposite to the imaging side of the structure, as viewed from the imaging side of the structure. This is converted into the reverse damage diagram of FIG.

  The damage diagram inversion unit 44 of this example mirrors and inverts non-text components such as CAD drawings and damaged figures by the mirror inversion unit 36, while the member name, element number, damage type, rank information, and damage feature amount. This is preferable in that the position in the figure is changed without mirror-inverting the text component. However, the present invention includes a case where the text component is mirror-inverted similarly to the non-text component. By reversing the CAD drawing and damaged figure of the non-text component, it becomes easy to visually recognize at least whether the shape and position of the damaged figure are correct. For example, it becomes possible to compare with a sketch of a damaged state when the bridge 1 is viewed from below.

  The operation unit 24 receives a reversing operation related to the damage diagram. The display control unit 32 switches between the state where the damage diagram shown in FIG. 6 is displayed on the display unit 22 and the state where the reverse damage diagram shown in FIG. .

  Next, an example of damage diagram editing processing to which the damage diagram editing method of the present invention is applied will be described.

  FIG. 8 is a flowchart showing the flow of the first damage diagram editing process example in the first embodiment. This process is executed by the CPU 30 according to a program stored in the storage unit 50.

  First, a CAD drawing showing the bridge 1 is input by the drawing input unit 28 (step S2). The input CAD drawing is displayed on the display unit 22 by the display control unit 32 (step S4). FIG. 9 shows an example of a CAD drawing. “DsXXXX” (Ds0101 to Ds0104 and Ds0201 to DS0204) in the figure is an element number for identifying a space that is an element of the floor slab 6 of the bridge 1. Here, “Ds” is a symbol representing “floor slab”, and “XXXX” is a grid-like array position of a space that is a range surrounded by the main beam 2 and the horizontal beam 3 of the floor slab 6 It is a number which shows. In other words, the floor slab 6 of this example is composed of a plurality of spaces in a lattice arrangement, and an element number is assigned to each space. The CAD drawing 80 of this example includes rectangular frame information of a case. The element number DsXXXX in the drawing may be omitted from the display unit 22. The coordinate axes Gx, Gy, and Gz of the global coordinate system with the bridge 1 as a reference are described in the drawing for later explanation, and the display on the display unit 22 may be omitted.

  Next, the image of the floor slab 6 is input by the image input unit 26 (step S6). That is, an image obtained by imaging the floor slab 6 to be inspected by the imaging device 10 for each space of the grid arrangement is input. In this example, an image is input for each case, but a plurality of images may be input collectively.

  Next, the image correction unit 34 performs necessary image correction among enlargement / reduction (scale correction), tilt correction, and rotation on the image of the case (step S8). That is, the correction regarding the mismatch in the distance or angle between the floor slab 6 and the imaging device 10 across a plurality of spaces is performed. Note that this step can be omitted when there is no mismatch in distance and angle across a plurality of cases.

  Next, the mirror inversion unit 36 performs mirror inversion on the image of the case (step S10). FIG. 10 shows an image IMG11 between the elements having the element number Ds0101. This image IMG11 is an image showing a damaged state viewed from the lower side of the bridge 1, and is an image showing a damaged state of one of the floor slabs 6. FIG. 11 shows a mirror image IMG12 obtained by mirror-inverting the image IMG11 of FIG. In this example, since the coordinate axis Gx of the global coordinate system with the bridge 1 as a reference matches the left-right direction (x direction) of the image IMG11, the mirror image is inverted by using the image IMG11 as the mirror inversion. IMG 12 is acquired. That is, the direction of the mirror reversal axis MAx in this example is the left-right direction (x direction) of the image IMG11.

  Next, the display control unit 32 causes the mirror image IMG12 to be superimposed on the CAD drawing 80 and displayed on the display unit 22 (step S12). 12 shows an example in which the mirror image IMG12 shown in FIG. 11 is superimposed and displayed on the CAD drawing 80 shown in FIG. In the mirror image IMG12, unnecessary portions are trimmed. In this example, the edge of the case in the mirror image IMG 12 is aligned with the edge of the case in the CAD drawing 80.

  Next, the damage detection unit 40 analyzes the mirror image IMG12 and detects a damage image from the mirror image IMG12 (step S14). For example, a cracked image is detected from the mirror image IMG12.

  Next, the feature amount of damage is measured by the editing unit 42 based on the mirror image IMG12 (step S16). For example, the width and interval of cracks are measured as feature quantities.

  Next, the editing unit 42 edits each element of the damage diagram (step S18). FIG. 13 shows a display example of an editing screen related to a case to which the element number Ds0101 of the floor slab 6 is assigned. In this example, the CAD drawing 80 and the mirror image IMG12 are displayed on the display unit 22, and at the same time, the damage list 82 is displayed. In this example, since a crack is detected in the above-described step S14 between the element numbers Ds0101, the “type” (type of damage) “crack” is automatically added to the damage list 82 by the editing unit 42. Will be filled in. Further, as the feature amount of the “crack” between the element numbers Ds0101, the width and interval of the “crack” are measured in the above-described step S16, so the editing unit 42 puts them in the “dimension” column of the damage list 82. Completed automatically. Items that are not automatically entered by the editing unit 42 can be input by the operation unit 24. For example, when water leakage and free lime can be visually recognized in the mirror image IMG 12, the type “water leakage + free lime” can be input by the operation unit 24.

  Further, when an undetected crack is automatically visible in the mirror image IMG 12, the type and size of the crack can be input by the operation unit 24. Although not shown in FIG. 13, a scale image for measuring the size of a crack can be displayed on the display unit 22, and the size of an undetected crack can be measured using the scale image. It is. In order to reflect the undetected crack in the damage diagram, the operation unit 24 can perform a tracing operation on the damaged image in the mirror image IMG12. For example, when the operation unit 24 is configured by a touch panel, if a cracked image in the mirror image IMG12 is traced with a finger or a pen, the trace of the trace is added to the damage diagram as a damaged figure. Here, the shape and position of the crack image in the mirror image IMG12 in the CAD drawing 80 correspond to the shape and position of the actual crack when the bridge 1 is viewed from the upper side (the side opposite to the imaging side). Therefore, it is possible to input easily and accurately.

  The “classification” in the damage list 82 is a column for inputting an evaluation classification (also referred to as “rank information”) of the degree of damage. FIG. 14 is a diagram schematically illustrating an example of a crack progression model in the floor slab 6. In this progression model, the evaluation category RANK is expressed in five stages from “a” to “e”. The correspondence relationship between each evaluation category RANK and the crack state STATE is as follows.

  a: No damage.

  b: A state in which a plurality of cracks are generated in parallel along the lateral direction (short direction perpendicular to the direction of vehicle travel). This is the stage where multiple cracks due to drying shrinkage become parallel beams.

  c: A state in which a crack in the vertical direction (longitudinal direction parallel to the vehicle traveling direction) and a crack in the horizontal direction intersect each other. This is a stage in which a plurality of cracks are formed in a lattice shape due to a live load, and the crack density in the lattice-shaped region increases. In the second half, cracks penetrate in the vertical direction of the floor slab (vertical direction perpendicular to the floor slab lower surface).

  d: The crack density in the lattice-shaped region exceeds the specified value, and the fracture surfaces of the plurality of cracks that have penetrated are in a smoothed state. This is the stage where the slab loses shear resistance due to the polishing action.

  e: State in which dropout has occurred. Dropout occurs due to wheel load exceeding the reduced punching shear strength.

  Next, it is determined whether or not editing for all elements has been completed (step S20). In this example, it is determined whether or not editing has been completed for all the spaces constituting the floor slab 6 (in this example, element numbers Ds0101 to Ds0104 and Ds0201 to Ds0204).

  If there is an unedited element (NO in step S20), the process returns to step S6. When editing for all elements has been completed (YES in step S20), editing for the entire damage diagram is performed (step S22). In this step, for example, a soundness determination category related to the entire floor slab 6 is input by the operation unit 24.

  Next, the damage diagram that has been edited is output (step S24). The damage diagram can be displayed on the display unit 22 by the display control unit 32, or can be printed out by a printer (not shown) via the network. For example, the damage diagram shown in FIG. 6 is printed out by a printer. The damage diagram can be uploaded to a database (not shown) via a network.

  The damage diagram shown in FIG. 6 does not include a mirror image, but the present invention is not limited to such a case. A mirror image may be included in the damage diagram. In addition, a mirror image may be embedded in the damage diagram instead of entering the damage graphic. That is, the editing content of the damage diagram by the editing unit 42 may be changed as appropriate according to the format of the required or allowed damage diagram.

  As mentioned above, although the processing example at the time of inputting the image for every space of floor slab 6 was explained, when a plurality of divided images taken by dividing the space into multiple times are input, a plurality of divided images are input. It is preferable to compose one composite image for each case. Hereinafter, an example of damage diagram editing processing will be introduced, divided into a case where a plurality of divided images are combined after mirror reversal and a case where a plurality of divided images are mirrored after reversal.

  FIG. 15 is a flowchart illustrating a flow of a second damage diagram editing process example according to the first embodiment. This process is executed by the CPU 30 according to a program stored in the storage unit 50. The same steps as those in the first damage diagram editing process example shown in FIG. 8 are denoted by the same reference numerals, and the description thereof will be omitted below.

  In this example, the image input unit 26 inputs a plurality of divided images of the floor slab 6 of the bridge 1 (step S102). Next, the image correction unit 34 performs necessary image correction on each divided image (step S104). Next, the mirror reversing unit 36 mirrors each divided image (step S106). Next, a plurality of the mirror-inverted divided images (mirror images) are displayed on the display unit 22 in a superimposed manner on the CAD drawing showing the bridge 1 viewed from the side opposite to the imaging side (step S108). . Next, the image synthesizing unit 38 synthesizes a plurality of mirror-inverted divided images (step S110).

  FIG. 16 is a flowchart illustrating a flow of a third damage diagram editing process example according to the first embodiment. This process is executed by the CPU 30 according to a program stored in the storage unit 50. The same steps as those in the first damage diagram editing process example shown in FIG. 8 are denoted by the same reference numerals, and the description thereof will be omitted below.

  In this example, the image input unit 26 inputs a plurality of divided images of the floor slab 6 of the bridge 1 (step S202). Next, the image correction unit 34 performs necessary image correction on each divided image (step S204). Next, a plurality of divided images (non-mirrored images) are displayed on the display unit 22 so as to be superimposed on the CAD drawing showing the bridge 1 viewed from the imaging side (step S206). Next, the image composition unit 38 composes a plurality of divided images (step S208). Next, the composite image is mirror-inverted by the mirror inversion unit 36 (step S210). The CAD drawing can be mirror-inverted with the composite image.

[Second Embodiment]
FIG. 17 is a block diagram illustrating a configuration example of the damage diagram editing apparatus 200 according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same component as the damage drawing editing apparatus 20 in 1st Embodiment shown in FIG. 2, and the content already demonstrated is abbreviate | omitted.

  The damage diagram editing apparatus 200 according to the second embodiment includes a damage diagram input unit 60 that inputs a damage diagram indicating a state of damage viewed from the side opposite to the imaging side of the structure.

  The damage diagram inversion unit 44 of this example converts the damage diagram input by the damage diagram input unit 60 into an inversion damage diagram showing the state of damage viewed from the imaging side of the structure.

  The display control unit 32 of the present example displays the first existing damage diagram display function for simultaneously displaying the input damage diagram and the mirror image on the display unit 22, and the reverse damage diagram and the non-mirror image. And a second existing damage diagram display function to display simultaneously.

  According to the first existing damage diagram display function, the progress of damage is compared with the past damage state viewed from the side opposite to the imaging side of the structure (for example, the upper side of the bridge 1) and the current mirror image. You can check the situation.

  According to the second existing damage map display function, the progress of damage is confirmed by comparing the past damage state viewed from the imaging side of the structure (for example, the lower side of the bridge 1) with the current image. Can do.

[Variation of mirror reversal]
In the first embodiment and the second embodiment described above, the case where the direction of the mirror reversal axis is fixed has been described as an example in order to facilitate the understanding of the present invention. It is not limited to the case where the direction of the mirror reversal axis is fixed. The present invention may have a configuration in which the direction of the mirror reversal axis is variable.

  The mirror reversing unit 36 has a function of determining the direction of the mirror reversal axis based on various information. The mirror reversing unit 36 performs mirror reversal around the mirror reversal axis in the determined direction.

  First, there is a mode in which an image input by the image input unit 26 (an image before mirror reversal) is subjected to image analysis, and the direction of the mirror reversal axis is determined based on the result of the image analysis.

  For example, it is assumed that an image IMG21 for each space of the floor slab 6 shown in FIG. 18 is acquired. This image IMG21 includes an image EG (hereinafter referred to as an “edge image”) of the edge of the case. In the real space, the shape of the edge portion of the case is a rectangle, and the two sides that form a rectangle are generally different in length. That is, the edge rectangle has a long side and a short side orthogonal to each other. In the real space, two sides of the edge rectangle that are orthogonal to each other have the same direction as the two coordinate axes Gx and Gy in the overall coordinate system with the bridge 1 as a reference. Therefore, the mirror reversing unit 36 detects an edge image from an image before mirror reversal (or a composite image in the case of divided imaging), and after projecting and converting the edge image into a rectangle as necessary. The direction of the mirror reversal axis can be determined based on the direction of one of the long side and the short side of the rectangle orthogonal to each other. However, the imaging target of the present invention (which is the target of inspection) is not limited to the floor slab, and the direction of the mirror inversion axis may be determined based on the geometric characteristics of the other imaging target. Needless to say.

  Second, the coordinate axes of the overall coordinate system (which is the “first coordinate system”) based on the structure and the local coordinate system (the “second coordinate system”) based on the imaging device 10 that captured the image. There is a mode in which the direction of the mirror reversal axis is determined based on the angle formed by the coordinate axis.

  For example, as shown in FIG. 19, an image obtained by imaging by the imaging device 10 mounted on the robot device 70 is input by the image input unit 26, and imaging device control information according to the imaging device control of the robot device 70 is obtained. Is input by the image input unit 26. As shown in FIG. 20, the imaging apparatus control information includes coordinate axes Gx, Gy, Gz of the global coordinate system with the bridge 1 as a reference, and coordinate axes Lx, Ly, Lz of a local coordinate system with the imaging apparatus 10 as a reference. Angle information indicating an angle formed by and is included. In the local coordinate system of this example, one of the three coordinate axes Lx, Ly, and Lz orthogonal to each other is the imaging direction (also referred to as the optical axis direction) of the imaging apparatus 10 and the floor slab 6 of the bridge 1. Orthogonal to (the surface to be imaged). In other words, in this example, the direction of one coordinate axis Gz in the overall coordinate system and the direction of one coordinate axis Lz in the local coordinate system coincide.

  The robot apparatus 70 of this example is a suspended robot suspended from a bridge, and FIG. 19 shows only the main part related to imaging. The suspended robot may be a robot that hangs on a traveling body (vehicle) on the bridge instead of hanging on the bridge. Further, the present invention can also be applied to a case where an unmanned flying robot such as a drone (unmanned flying vehicle) is used instead of the suspended robot.

  The robot apparatus 70 of this example includes an imaging apparatus control mechanism 72 that controls the movement and rotation of the imaging apparatus 10. The imaging device control mechanism 72 rotates the imaging device 10 in the pan direction P and the tilt direction T, respectively, and an XYZ movement mechanism that can move the imaging device 10 in the Gx direction, the Gy direction, and the Gz direction orthogonal to each other. It also serves as a possible pan / tilt mechanism.

  The mirror reversing unit 36 determines the direction of the mirror reversal axis based on angle information indicating an angle formed by the coordinate axis Gx (or Gy) of the global coordinate system and the coordinate axis Lx (or Ly) of the local coordinate system. Is possible.

  When the imaging device 10 is rotated in the pan direction P, that is, when the azimuth angle of the imaging device 10 is variable with respect to the overall coordinate system with respect to the bridge 1, the mirror reversing unit 36 uses the overall coordinate system. The direction of the mirror reversal axis can be determined based on the azimuth angle of the imaging device 10 with respect to the coordinate axis Gx or Gy.

  Since there are various setting modes of the coordinate axes Lx, Ly, and Lz of the local coordinate system with respect to the coordinate axes Gx, Gy, and Gz of the global coordinate system and pan / tilt modes (angle control modes) of the imaging apparatus 10, the local coordinates What is necessary is just to acquire the angle information according to the setting mode of the coordinate axis of the system and the angle control mode of the imaging device 10 and determine the direction of the mirror reversal axis based on the angle information.

[Client server type]
In the client server type system, the damage diagram editing device may be configured by at least one of the client device and the server device. In other words, the damage diagram editing apparatus of the present invention may be configured by one or a plurality of computer apparatuses of a client server type system.

  As mentioned above, although the form for implementing this invention has been demonstrated, this invention is not limited to embodiment and the modification which were mentioned above, A various deformation | transformation is possible in the range which does not deviate from the main point of this invention.
