[0016] The embodiments will be described in detail below with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection configurations of components, steps, and the order of steps shown in the following embodiments are examples only and are not intended to limit the present invention. Furthermore, components in the following embodiments that are not described in an independent claim will be described as optional components.

[0017] Please note that each figure is a schematic diagram and not necessarily a strictly accurate representation. Furthermore, in each figure, substantially identical components are denoted by the same reference numerals, and redundant explanations may be omitted or simplified.

[0018] (Embodiment) [composition] First, the configuration of the inspection support system according to the embodiment will be described. FIG. 1 is a block diagram showing the configuration of the inspection support system according to the embodiment.

[0019] The inspection support system 10 is a system that can support the reinforcement inspection by workers at the construction site. The reinforcement inspection is an inspection to confirm whether the arrangement of steel bars, the thickness of steel bars (bar diameter), and the number of steel bars, etc. in a building under construction match the design information (design drawings). FIG. 2 is a diagram showing a worker who performs the reinforcement inspection using the inspection support system 10. The worker can perform the reinforcement inspection relatively easily by taking an image of the steel bar structure to be inspected using the portable inspection support device 20.

[0020] As shown in FIG. 1, the inspection support system 10 includes an inspection support device 20 and a server device 30.

[0021] The inspection support device 20 is a portable information terminal used by workers to perform the reinforcement inspection. The inspection support device 20 is realized, for example, by attaching a dedicated adapter to a general-purpose information terminal such as a smartphone or a tablet terminal, but it may also be a dedicated information terminal. Specifically, the inspection support device 20 includes an operation reception unit 21, a display unit 22, an information processing unit 23, a storage unit 24, a communication unit 25, an imaging unit 26, and an acceleration sensor 27.

[0022] The operation reception unit 21 receives the input (manual operation) of the worker. The operation reception unit 21 is realized, for example, by a touch panel.

[0023] The display unit 22 displays an image. The display unit 22 is realized, for example, by a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel.

[0024] The information processing unit 23 performs information processing to support the worker's inspection of the reinforcement bar. The information processing unit 23 is implemented by, for example, a microcomputer, but may also be implemented by a processor. The information processing unit 23 includes, as functional components, an acquisition unit 23a, a generation unit 23b, a grouping unit 23c, a display control unit 23d, and an inspection unit 23e. The functions of the acquisition unit 23a, the generation unit 23b, the grouping unit 23c, the display control unit 23d, and the inspection unit 23e are realized, for example, by the microcomputer or processor constituting the information processing unit 23 executing a computer program stored in the storage unit 24. The detailed functions of the acquisition unit 23a, the generation unit 23b, the grouping unit 23c, the display control unit 23d, and the inspection unit 23e will be described later.

[0025] The memory unit 24 is a storage device that stores computer programs executed by the information processing unit 23, as well as various information necessary for the information processing unit 23 to perform the above processing. The memory unit 24 is implemented, for example, by semiconductor memory.

[0026] The communication unit 25 is a communication module (communication circuit) that enables the inspection support device 20 to communicate with the server device 30 via a wide-area communication network 90 such as the Internet. The communication performed by the communication unit 25 is, for example, wireless communication. The communication standard used for communication is not particularly limited.

[0027] The imaging unit 26 captures an image. The imaging unit 26 is a stereo camera capable of measuring, for example, the distance from the position of the inspection support device 20 when capturing an image to the subject appearing in the image.

[0028] The acceleration sensor 27 detects the acceleration applied to the inspection support device 20. The acceleration sensor 27 is used to detect the position (displacement), orientation, and vertical direction of the inspection support device 20 when an operator takes an image using the inspection support device 20.

[0029] The server device 30 communicates with the inspection support device 20 (communication unit 25) to receive login information entered by the worker into the inspection support device 20, and performs authentication of the received login information (in other words, user authentication). If user authentication is successful, the server device 30 sends a usage permission notification to the inspection support device 20. Upon receiving the usage permission notification, the inspection support device 20 becomes ready to perform rebar inspection. The following example of operation is assumed to occur after successful user authentication.

[0030] [Example of operation] Next, we will describe an example of the operation of the inspection support device 20, which assists workers in inspecting the reinforcement bar placement. Figure 3 is a flowchart of the operation example of the inspection support device 20.

[0031] When a predetermined input screen (not shown) is displayed on the display unit 22 of the inspection support device 20, the operator performs a selection operation to select design information corresponding to the reinforced concrete structure to be inspected from among multiple design information stored in the storage unit 24. The operation reception unit 21 receives the design information selection operation (S11), and the acquisition unit 23a acquires the selected design information from the storage unit 24 (S12). Figure 4 is a diagram showing an example of design information. The design information shown in Figure 4 is information that shows the design reinforcement arrangement of a column in a building, and specifically, it shows the types of reinforcement bars (main reinforcement and stirrups) included in the column and the arrangement of each type of reinforcement bar. Specifically, the design information shown in Figure 4 shows the arrangement of multiple main reinforcement bars that are long in the vertical direction and multiple stirrups that are processed into a rectangle to surround the main reinforcement bars. In step S12, design information showing the reinforcement arrangement of a column as shown in Figure 4 is acquired. Examples of parts other than columns include beams, walls, or slabs.

[0032] Next, the worker performs a shooting operation to photograph the reinforcing steel structure to be inspected, and the operation reception unit 21 receives the shooting operation (S13). Based on the received shooting operation, the acquisition unit 23a uses the imaging unit 26 to capture an image (still image) of the reinforcing steel structure and acquires the image information of the captured image (S14). As described above, the imaging unit 26 is a stereo camera, and in step S14, image information of two images taken from different shooting positions is acquired in a single shooting operation. In other words, the image information includes the actual image data of the two images (stereo images) and viewpoint information (information indicating the distance between the shooting positions). Here, it is assumed that the reinforcing steel structure of a column, as shown in Figure 2, is to be photographed. Image capture may be performed multiple times, for example, by changing the shooting position, but it is sufficient to perform it at least once.

[0033] Next, the generation unit 23b generates a three-dimensional model of the reinforcing bar structure shown in the image based on the image information acquired in step S14 (S15). Specifically, the generation unit 23b can determine the distance from the inspection support device 20 to each part of the reinforcing bar structure based on the two actual image data and viewpoint information included in the image information, and can generate a three-dimensional model of the reinforcing bar structure based on the determined distance. A detailed explanation of the method for generating the three-dimensional model is omitted.

[0034] In step S15, the 3D model generated may contain reinforcing bars that are not intended for inspection. For example, when taking images at a construction site, unintended reinforcing bars may be captured in the images, resulting in the 3D model containing actual reinforcing bars that are not intended for inspection. In addition, the 3D model may contain non-existent reinforcing bars that are not intended for inspection due to false detection.

[0035] In order to exclude reinforcing bars that have been incorrectly detected by the inspection support device 20 from the inspection, the following steps S16 to S18 are performed, and the worker selects the reinforcing bar to be inspected from among the multiple reinforcing bars included in the 3D model.

[0036] The grouping unit 23c detects multiple reinforcing bars (more specifically, 3D models of multiple reinforcing bars) from the 3D model generated in step S15, and groups the detected multiple reinforcing bars (S16).

[0037] For example, if column design information is selected in step S12, the grouping unit 23c detects vertically long reinforcing bars from the 3D model, assigns individual identification information to each detected reinforcing bar, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects main reinforcing bars from the 3D model and manages the detected main reinforcing bars as a single group. The vertical direction can be detected using the acceleration sensor 27.

[0038] Furthermore, the grouping unit 23c detects reinforcing bars that intersect perpendicularly with the main reinforcement (reinforcing bars that are long horizontally), assigns individual identification information to each detected reinforcing bar, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects stirrups from the 3D model and manages the detected stirrups as a single group.

[0039] Next, the display control unit 23d displays a selection screen on the display unit 22 for the worker to select the reinforcing bars to be inspected (S17). Figure 5 shows an example of the selection screen. The selection screen in Figure 5 includes a first area 22a where the image taken in step S14 is displayed, a second area 22b where second objects (buttons) for selecting reinforcing bars are arranged, and a third area 22c where a cross-sectional view of the 3D model is displayed.

[0040] The image displayed in the first region 22a is superimposed with a first object 22d for selecting reinforcing bars. The first object 22d is assigned individual identification information (numbers 0 to 11 in Figure 5) that was assigned in step S16. The display control unit 23d can assign identification information of reinforcing bars detected in the 3D model to the corresponding reinforcing bars in the image, based on the correspondence between the reinforcing bar structure shown in the image and the 3D model of the reinforcing bar structure.

[0041] In the second area 22b, multiple second objects corresponding to the individual identification information assigned in step S16 are displayed.

[0042] The third area 22c displays a cross-sectional view of the 3D model. The cross-section displayed is automatically determined according to the design information (parts such as columns) acquired in step S12. In other words, different design information will result in different displayed cross-sections. If the design information for a column (Figure 4) is acquired in step S12, the third area 22c displays a cross-section cut in a horizontal plane (i.e., a cross-section of the main reinforcement). The main reinforcement displayed in the cross-sectional view of the third area 22c is also assigned the individual identification information assigned in step S16.

[0043] The display control unit 23d can switch the display and hiding of the first object 22d and the second object 22e on a group basis. When the first toggle switch 22f at the top of the second area 22b is turned on and off, the display of the first object 22d and the second object 22e of the main reinforcement detected in step S16 is turned on and off, and when the second toggle switch 22g is turned on and off, the display of the first object 22d and the second object 22e of the stirrups detected in step S16 is turned on and off.

[0044] In Figure 5, the first toggle switch 22f is ON and the second toggle switch 22g is OFF, so only the first object 22d and second object 22e of the main reinforcement are displayed, and the first object 22d and second object 22e of the stirrups are not displayed. If the second toggle switch 22g is turned ON in addition to the first toggle switch 22f, the selection screen will display the first object 22d and second object 22e of the main reinforcement, as well as the first object 22d and second object 22e of the stirrups. In other words, more objects will be displayed on the selection screen than shown in Figure 5, making it difficult for the worker to quickly select the desired object.

[0045] When the selection screen described above is displayed, the operator performs a selection operation to select the reinforcing bar to be inspected, and the operation reception unit 21 accepts the selection operation for the reinforcing bar (S18). The selection operation here includes both the selection operation for the first object 22d and the selection operation for the second object 22e. For example, when the operator selects the first object 22d to which individual identification information "0" has been assigned, the first object 22d to which individual identification information "0" has been assigned, the reinforcing bar corresponding to individual identification information "0" shown in the image in the first region 22a, the second object 22e to which individual identification information "0" has been assigned, and the reinforcing bar in the third region 22c (cross-sectional view) to which individual identification information "0" has been assigned become active (indicated as selected). Figure 6 shows an example of the selection screen when one reinforcing bar is actively displayed. Active display means that the selected object is displayed in a different manner from the unselected object, and specifically means that the selected object is displayed in a different color from the unselected object.

[0046] Furthermore, if the operator selects the second object 22e to which individual identification information "0" has been assigned, the first object 22d to which individual identification information "0" has been assigned, the reinforcing bar corresponding to individual identification information "0" shown in the image within the first region 22a, the second object 22e to which individual identification information "0" has been assigned, and the reinforcing bar in the cross-sectional view to which individual identification information "0" has been assigned will all be displayed as active. In other words, the operator is allowed to both select the reinforcing bar by manipulating the first object 22d and to perform the reinforcing bar operation by manipulating the second object 22e.

[0047] In step S18, if the worker wants to select the main reinforcement for inspection, they simply turn on the first toggle switch 22f and turn off the second toggle switch 22g. This displays only the first object 22d and second object 22e of the main reinforcement, while the first object 22d and second object 22e of the stirrups are not displayed, allowing the worker to quickly select the main reinforcement and reducing the likelihood of incorrect selection.

[0048] Next, the inspection unit 23e inspects the reinforcement structure by comparing a 3D model containing only the reinforcement bars selected in step S18 with the design information acquired in step S12 (S19). If main reinforcement bars were selected in step S18, the inspection unit 23e compares the 3D model containing only the main reinforcement bars with the design information to check whether the arrangement of the main reinforcement bars, the thickness of the main reinforcement bars, and the number of main reinforcement bars match the design information (design drawings). The inspection unit 23e then displays the inspection results on the display unit 22 and stores them in the storage unit 24.

[0049] As described above, the inspection support device 20 can assist workers in inspecting reinforcement bars. The inspection support device 20 groups multiple reinforcing bars included in the 3D model of the reinforced concrete structure and has a function to switch the display and hiding of multiple objects (multiple first objects 22d or multiple second objects 22e) on the display unit 22 for selecting the reinforcing bars to be inspected, on a group-by-group basis. With such an inspection support device 20, workers can quickly select the reinforcing bars to be inspected by hiding the objects corresponding to the reinforcing bars that are not to be inspected.

[0050] [Variations in the method of grouping reinforcing bars] The above example illustrates the case where the reinforced concrete structure being inspected corresponds to a building column. Here, we will provide supplementary information on the grouping method when the reinforced concrete structure being inspected is a beam, wall, or slab.

[0051] When a reinforced concrete structure corresponds to a beam in a building, the structure includes multiple main reinforcement bars that are long horizontally, and multiple stirrups that are rectangular in shape and surround the main reinforcement bars.

[0052] In this case, the grouping unit 23c detects long reinforcing bars in the image from within the 3D model, assigns individual identification information to each detected reinforcing bar, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects main reinforcing bars from within the 3D model and manages the detected main reinforcing bars as a single group.

[0053] Furthermore, the grouping unit 23c detects reinforcing bars that intersect perpendicularly with the main reinforcement (reinforcing bars that are long in the vertical direction in the image), assigns individual identification information to each detected reinforcing bar, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects stirrups from the 3D model and manages the detected stirrups as a single group.

[0054] When a reinforced concrete structure corresponds to a building wall, the reinforced concrete structure includes multiple vertically long reinforcing bars and multiple horizontally long reinforcing bars.

[0055] In this case, the grouping unit 23c detects vertically long reinforcing bars from the 3D model, assigns individual identification information to each detected reinforcing bar, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects vertical reinforcing bars from the 3D model and manages the detected vertical reinforcing bars as a single group. The vertical direction can be detected using the acceleration sensor 27.

[0056] Furthermore, the grouping unit 23c detects reinforcing bars that intersect perpendicularly with the main reinforcement (reinforcing bars that are long horizontally), assigns individual identification information to each detected reinforcing bar, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects horizontal reinforcement from the 3D model and manages the detected horizontal reinforcement as a single group.

[0057] When the reinforced concrete structure corresponds to the slab of a building, the reinforced concrete structure includes a plurality of main reinforcements, each long in a first direction along the horizontal plane and aligned in the same plane, and a plurality of distribution reinforcements, each long in a second direction along the horizontal plane and perpendicular to the first direction, and aligned in the same plane.

[0058] In this case, the user performs a direction specification operation to specify either the first direction or the second direction in the image, and the operation reception unit 21 accepts the direction specification operation. This determines the first and second directions in the image.

[0059] Subsequently, the grouping unit 23c detects reinforcing bars that are long in the first direction in the image from within the 3D model, assigns individual identification information to each of the detected reinforcing bars, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects main reinforcing bars from within the 3D model and manages the detected main reinforcing bars as a single group.

[0060] Furthermore, the grouping unit 23c detects long reinforcing bars in the second direction, assigns individual identification information to each detected reinforcing bar, and also assigns common group identification information to the detected reinforcing bars. In other words, the grouping unit 23c detects distribution reinforcing bars from the 3D model and manages the detected distribution reinforcing bars as a single group.

[0061] In this way, the grouping section 23c can change the grouping conditions (reinforcement detection conditions) according to which part of the building the reinforced concrete structure belongs to, and can group multiple reinforcements included in the 3D model according to the type of reinforcement defined in the design information (main reinforcement, stirrups, vertical reinforcement, horizontal reinforcement, and distribution reinforcement, etc.).

[0062] Furthermore, the grouping (detection) of reinforcing bars may be performed based on the diameter of the reinforcing bar (the thickness of the reinforcing bar). In other words, the grouping section 23c may group reinforcing bars of the same diameter into the same group.

[0063] [Variations in the method of selecting reinforcing bars] In the above example, the selection of multiple reinforcing bars included in the 3D model was performed one by one by the operator. However, the inspection support device 20 may have an operating mode that allows the operator to select two or more reinforcing bars at once.

[0064] For example, in the selection screen of Figure 5, if the worker selects a reinforcing bar with individual identification information "0" and a reinforcing bar with individual identification information "9", in addition to these two reinforcing bars, a reinforcing bar with individual identification information "1" and a reinforcing bar with individual identification information "5", which are located on the same plane as these two reinforcing bars, may also be selected.

[0065] Furthermore, if a worker selects a reinforcing bar with individual identification information of "0" and a reinforcing bar with individual identification information of "9", all other reinforcing bars with the same diameter as these two may also be selected. Similarly, if a worker selects a reinforcing bar with individual identification information of "0" and a reinforcing bar with individual identification information of "9", all other reinforcing bars with the same longitudinal direction as these two may also be selected.

[0066] In other words, the display control unit 23d may have a mode in which, when two objects are selected from a plurality of objects (a plurality of first objects 22d or a plurality of second objects 22e), in addition to the two objects, other objects that satisfy the conditions determined by the two objects are actively displayed (displayed in a different manner from the unselected objects). Here, "satisfying the conditions determined by the two objects" can be rephrased as "similar in orientation or specifications to the two objects," etc.

[0067] Such an inspection support device 20 allows the worker to select two or more reinforcing bars at once. Therefore, the worker can quickly select the reinforcing bars to be inspected.

[0068] [Other variations] In the above embodiment, multiple first objects 22d and multiple second objects 22e were displayed on the selection screen. However, it is sufficient for at least one of the multiple first objects 22d and multiple second objects 22e to be displayed, and it is not necessary for both the multiple first objects 22d and multiple second objects 22e to be displayed.

[0069] In the above embodiment, image information from images captured by a stereo camera was used to generate a three-dimensional model of the reinforced concrete structure. However, the inspection support device 20 may be equipped with a ToF (Time of Flight) camera as the imaging unit 26, and the generation unit 23b may generate a three-dimensional model of the reinforced concrete structure based on image information from images (distance images) captured by the ToF camera.

[0070] Furthermore, the inspection support device 20 may be equipped with a 3D scanner such as LiDAR (Light Detection And Ranging), and may generate a 3D model of the reinforced concrete structure based on point cloud data showing the unevenness of the reinforced concrete structure acquired by the 3D scanner.

[0071] In the above embodiment, the specifications of the GUI (Graphical User Interface) on the confirmation screen are merely an example. For instance, the display and hiding of multiple objects on the display unit 22 may be performed using tabs or the like instead of toggle switches.

[0072] In the above embodiment, some of the processes described as being performed by the inspection support device 20 may be performed by the server device 30. For example, the 3D model generation process may be performed by the server device 30.

[0073] [Effects, etc.] The following describes examples of inventions that can be obtained from the disclosures in this specification, and explains the effects and other benefits that can be obtained from these examples.

[0074] Invention 1 is an inspection support system 10 for assisting in the inspection of a reinforced concrete structure, comprising: an acquisition unit 23a for acquiring image information of an image showing the reinforced concrete structure; a generation unit 23b for generating a three-dimensional model of the reinforced concrete structure based on the acquired image information; a grouping unit 23c for grouping multiple reinforced concrete bars included in the generated three-dimensional model of the reinforced concrete structure; a display unit 22; and a display control unit 23d for selecting multiple reinforced concrete bars from among multiple reinforced concrete bars, which switches the display and hiding of multiple objects corresponding to multiple reinforced concrete bars on the display unit 22 for each group. Each of the multiple first objects 22d and multiple second objects 22e in the above embodiment is an example of multiple objects.
