[0105] The scaffold input step (S30) is where the scaffold structure for which quantities are to be calculated is input, depending on whether the virtual scaffold installation mode or the on-site scaffold measurement mode is used. Users can input the scaffold structure using the work interface provided in each mode.

[0106] The quantity calculation step (S50) is a step for calculating the quantity of materials required to install a scaffold based on the input scaffold structure. In the quantity calculation step (S50), when the scaffold structure is input, the material calculation method set for the scaffold structure is applied to calculate the quantity of materials. The quantity calculation step (S50) can also calculate the installation cost based on the quantity of materials and the scaffold structure. In the quantity calculation step (S50), the installation cost can be calculated by taking into account the height surcharge. The height surcharge refers to the quantity calculation standard that adds costs to scaffolds that are higher than a certain height, wider than a certain width, or larger than a certain area. Specific details regarding the height surcharge will be described later.

[0107] Below, the virtual ladder installation mode is first described.

[0108] FIG. 7 is a diagram illustrating a work history interface provided when a virtual ladder installation mode is selected according to one embodiment.

[0109] When a user selects a virtual scaffolding installation mode, the processor (10) can display a virtual scaffolding installation history interface as a pop-up window on the display (41). The virtual scaffolding installation history interface may be the initial screen entered when the virtual scaffolding installation mode is selected. The virtual scaffolding installation history interface may display a job number (C1) and a job name (C2) of a job performed in the virtual scaffolding installation mode. The job number may be displayed with 3 digits or less. The job name may be entered with 64 characters or less, and up to 16 characters may be displayed on the job interface. The number of characters allowed for the job number and the job name, and the display method, can be changed. The virtual scaffolding installation history interface may display a list (C3) of virtual scaffolding (4a) installation jobs performed. The virtual scaffolding installation history interface may include an add button (B3) for adding a job, and a delete button (B4) for deleting a job. When the add button is selected, a new virtual scaffolding (4a) installation job can be created. When a new virtual scaffold (4a) installation task is created, a pop-up window (not shown) may be displayed for entering a scaffold name. Selecting a virtual scaffold (4a) installation task from the list and pressing the delete button may delete the selected virtual scaffold (4a) installation task.

[0110] FIG. 7 is a flowchart showing each step of a method for verifying scaffold quantity using augmented reality performed in a virtual scaffold installation mode according to one embodiment.

[0111] When the user selects the virtual scaffold installation mode in the mode selection step (S20), the scaffold input step (S30) may be performed. The scaffold input step (S30) performed in the virtual scaffold installation mode may differ from each step of the scaffold input step (S30) performed in the field scaffold measurement mode.

[0112] According to one embodiment, in the virtual scaffolding installation mode, the scaffolding input step (S30) may include a step of displaying the ground (5) of the site (3) on the display (41) and recognizing the ground (5) (S31), a step of selecting a location to install the virtual scaffold (4a) on the ground (5) (S32), a step of selecting the type of the virtual scaffold (4a) (S33), a step of inputting the size of the virtual scaffold (4a) (S34), a step of displaying the virtual scaffold (4a) according to the type and size on the display (41) (S35), a step of adjusting the virtual scaffold (4a) displayed on the display (41) (S36), and a step of determining the structure of the virtual scaffold (4a) (S37).

[0113] And, the processor (10) can display the ground (5) of the site (3) on the display (41) in order to input the structure of the scaffold in the virtual scaffold installation mode, recognize the ground (5), provide a work interface for selecting a location to install a virtual scaffold (4a) on the ground (5), a work interface for selecting the type of the virtual scaffold (4a), and a work interface for inputting the size of the virtual scaffold (4a), display a virtual scaffold (4a) according to the type and size on the display (41), provide a work interface for adjusting the virtual scaffold (4a) displayed on the display (41), and perform an operation for determining the structure of the virtual scaffold (4a) based on the user's input.

[0114] In the virtual scaffold installation mode, the scaffold input step (S30) is a process of determining the structure of the virtual scaffold (4a) by overlapping the virtual scaffold (4a), which is an augmented reality object, on the field image taken of the field (3) where the scaffold is to be installed and displaying it on the display (41). In the scaffold input step (S30), the location, type, and size of the scaffold can be determined.

[0115] Fig. 9 is a drawing explaining a step of recognizing the ground (5) in a virtual ladder installation mode according to one embodiment.

[0116] When a new virtual scaffold (4a) installation task starts in the virtual scaffold installation mode, a step (S31) of recognizing the ground (5) may be performed first. The step (S31) of recognizing the ground (5) is a step of determining the ground (5) (ground) at the location where the virtual scaffold (4a) is to be installed. In the step (S31) of recognizing the ground (5), the processor (10) may display an on-site image generated by the camera (31) by photographing the on-site (3) in real time on the display (41). In the step (S31) of recognizing the ground (5), the work interface may provide a frame (F1) in the form of a picture frame and a guidance message (M1). The guidance message (M1) may include a method for the user to recognize the ground (5) by adjusting the camera (31). The guidance message (M1) may disappear after a predetermined time (e.g., 5 seconds). The user can adjust the camera (31) so that a portion of the ground (5) on which the ladder is to be installed is positioned within a frame (F1) in the form of a picture frame. Selecting the back button (B5) returns to the mode selection step (S20).

[0117] When a predetermined time has elapsed while the user adjusts the camera (31) to capture a location where the scaffolding is to be installed, the processor (10) can recognize the ground (5) based on the measurement value received from the sensor unit (30) and the on-site image captured by the camera (31). When the processor (10) recognizes the ground (5), a message indicating that the ground has been recognized can be displayed in a pop-up window.

[0118] Fig. 10 is a drawing showing a state in which a mark (K1) indicating a location where a scaffold is to be installed is displayed on the ground (5) in a virtual scaffold installation mode according to one embodiment.

[0119] When the processor (10) recognizes the ground (5) at the location where the ladder is to be installed, a step (S32) of selecting a location on the ground (5) at which the virtual ladder (4a) is to be installed can be performed.

[0120] In the step (S32) of selecting a location to install a virtual scaffold (4a), the processor (10) can display a mark (K1) indicating a location where the scaffold is to be installed on the display (41). The mark (K1) can be displayed in a form attached to the ground (5). The user can move the location of the mark (K1) by adjusting the direction of the camera (31) by moving the scaffold quantity verification device (1) using augmented reality. When the mark (K1) reaches a desired location in the field image displayed on the display (41), the user can select a placement button (B6). The work interface can provide the placement button (B6). When the user selects the placement button (B6), the processor (10) can recognize that the location indicated by the mark (K1) is a location where the virtual scaffold (4a) is to be installed. When the user selects the placement button (B6), the processor (10) can provide a pop-up work interface for selecting a scaffold type.

[0121] Fig. 11 is a drawing showing a step of selecting a type of virtual ladder (4a) in a virtual ladder installation mode according to one embodiment.

[0122] The step (S33) of selecting the type of the virtual scaffold (4a) is a step of providing a work interface including a pop-up window (W1) for receiving input of the type of the virtual scaffold (4a) from the user, and receiving the user's input. The type of the virtual scaffold (4a) may include a square, a hexagon, an octagon, etc. The type of the virtual scaffold (4a) may be in the shape of a bottom surface (BS). The type of the virtual scaffold (4a) may further include other shapes. The work interface may include buttons corresponding to a plurality of types (e.g., a square type button (B7), a hexagon type button (B8), an octagon type button (B9), etc.), a create button (B10), and a close pop-up window button (B11). When the close pop-up window button (B11) is selected, the process may return to the step (S32) of selecting a location for installing the virtual scaffold (4a).

[0123] The user can select one of the buttons (B7, B8, B9) corresponding to the type of the scaffold and select the create button (B10). The processor (10) can input the type of the virtual scaffold (4a) based on the user's button input. When the user selects the create button (B10), the processor (10) can perform a step of inputting the size of the virtual scaffold (4a).

[0124] Fig. 11 is a drawing showing a step of inputting the size of a virtual ladder (4a) in a virtual ladder installation mode according to one embodiment.

[0125] The step (S34) of inputting the size of the virtual scaffold (4a) is a step of providing a work interface including a pop-up window for the user to input the size of the virtual scaffold (4a), and receiving the user's input. The size of the virtual scaffold (4a) may include length, width, and height. The work interface may include an input space (D1) corresponding to the length, width, and height, a create button (B12), and a pop-up window close button (B13). The size of the scaffold may be input in meters (m). The user may adjust the unit of size in the settings of the scaffold quantity verification application (21).

[0126] When a user inputs a value smaller than the minimum size of the virtual ladder (4a), the processor (10) can display a value corresponding to the minimum size in the input space (D1). For example, when the minimum size of the virtual ladder (4a) is 1 m and the user inputs 0.5, the processor (10) can display 1 m in the input space.

[0127] When a user inputs a value smaller than the maximum size of the virtual ladder (4a), the processor (10) can display a value corresponding to the maximum size in the input space (D1). For example, when the maximum size of the virtual ladder (4a) is 60 m and the user inputs 65, the processor (10) can display 60 m in the input space.

[0128] The user can input numbers into the input spaces (D1) corresponding to the length, width, and height and select the Create button (B12). The Create button (B12) may be disabled if the user has not entered all values ​​corresponding to the length, width, and height. The Create button (B12) may be activated if the user has entered all values ​​corresponding to the length, width, and height. The Create button (B12) must be enabled for the user to select it.

[0129] When the processor (10) receives the size of the virtual ladder (4a), it can perform a step (S35) of displaying the virtual ladder (4a) according to the type and size on the display (41).

[0130] FIG. 13 is a drawing showing a state in which a step (S35) of displaying a virtual ladder (4a) according to the type and size input by the user on a display (41) has been performed according to one embodiment.

[0131] In the step (S35) of displaying a virtual scaffold (4a) according to type and size on the display (41), the processor (10) can generate a virtual scaffold (4a) which is an augmented reality object corresponding to the type and size of the virtual scaffold (4a) and display it on the display (41) by overlapping it with the field image. The virtual scaffold (4a) can be generated as an augmented reality object and displayed on the ground (5) where the mark (K1) is displayed. When the virtual scaffold (4a) is displayed on the display (41) as an augmented reality, a step of adjusting the virtual scaffold (4a) can be performed.

[0132] FIGS. 13, 14, 15, and 16 are diagrams illustrating steps for adjusting a virtual scaffold (4a) in a virtual scaffold installation mode according to one embodiment. FIG. 13 is a diagram illustrating a size adjustment step in a virtual scaffold installation mode according to one embodiment.

[0133] The step (S36) of adjusting the virtual scaffold (4a) is a step in which the user checks the virtual scaffold (4a) displayed on the display (41) on the field image, and adjusts the size, position, and rotation of the virtual scaffold (4a) to modify the structure of the virtual scaffold (4a). When the virtual scaffold (4a) generated according to the size of the scaffold input in the step (S34) of inputting the size of the virtual scaffold (4a) is displayed on the display (41), the user can check the virtual scaffold (4a) and the field (3) environment, and modify the size, position, and direction of the scaffold. In the step (S36) of adjusting the virtual scaffold (4a), the user can compare the field (3) environment and the virtual scaffold (4a) to adjust the size, position, and direction of the scaffold, thereby determining the structure of the virtual scaffold (4a) suitable for the field (3) environment.

[0134] According to one embodiment, the step (S36) of adjusting the virtual scaffold (4a) displayed on the display (41) includes a size adjustment step (S36a) of increasing or decreasing the size of a selected surface by selecting a surface button while a size increase button or a size decrease button displayed on the display (41) is selected, a position adjustment step (S36b) of touching the virtual scaffold (4a) displayed on the display (41) and dragging the virtual scaffold (4a) with one finger while the outline of the virtual scaffold (4a) is displayed, and moving the position of the virtual scaffold (4a) in the dragged direction, a rotation adjustment step (S36c) of touching the virtual scaffold (4a) displayed on the display (41) and dragging the virtual scaffold (4a) with two fingers while the outline of the virtual scaffold (4a) is displayed, and rotating the virtual scaffold (4a) in the dragged direction, and a lock button displayed on the display (41) is selected while the touch of the virtual scaffold (4a) is disabled while the direction key button displayed on the display (41) is selected while the virtual scaffold (4a) is rotated. It may include a locking movement step (S36d) for moving the ladder (4a) in the direction of the selected direction key.

[0135] The processor (10) can perform a size adjustment operation to increase or decrease the size of a selected surface by selecting a size increase button or a size decrease button displayed on the display (41) in order to adjust the virtual scaffold (4a), a position adjustment operation to move the position of the virtual scaffold (4a) in the dragged direction by touching the virtual scaffold (4a) displayed on the display (41) and touching and dragging the virtual scaffold (4a) with one finger while the outline of the virtual scaffold (4a) is displayed, a rotation adjustment operation to rotate the virtual scaffold (4a) in the dragged direction by touching and dragging the virtual scaffold (4a) with two fingers while the outline of the virtual scaffold (4a) is displayed, and a lock movement operation to move the virtual scaffold (4a) in the selected direction by selecting a direction key button displayed on the display (41) in order to disable the touch of the virtual scaffold (4a) by selecting a lock button displayed on the display (41).

[0136] The size adjustment step (S36a) is a step in which the user adjusts the size of the virtual scaffold (4a) using buttons provided in the work interface. In the size adjustment step (S36a), the work interface may provide a size increase button (B14), a size decrease button (B15), and a multiple face button (B16). The number of faces provided by the multiple face button (B16) may vary depending on the type of scaffold. In the case of a square type scaffold, the work interface may provide buttons for selecting the top face (B16a), front face (B16b), back face (B16c), left face (B16d), and right face (B16e).

[0137] The user can first select the size increase button (B14) or the size decrease button (B15), and then select the face button (B16). When the face button (B16) is selected while the size increase button (B14) is selected, the processor (10) can increase the size of the virtual scaffold (4a) in the corresponding face direction of the virtual scaffold (4a). For example, when the user selects the size increase button (B14) and the top button (B16a), the processor (10) can increase the height of the virtual scaffold (4a). When the user selects the size decrease button (B15) and the front button (B16b), the processor (10) can reduce the width of the virtual scaffold (4a) so that the front of the virtual scaffold (4a) moves in the back direction.

[0138] The user can repeatedly select the surface button (B16) while the size increase button (B14) or size decrease button (B15) is activated. When the surface button (B16) is repeatedly selected while the size increase button (B14) is selected, the processor (10) can increase the virtual scaffold (4a) in the selected surface direction by the selected number of times in a predetermined unit size. For example, when the top button (B16a) is selected three times while the size increase button (B14) is selected, the processor (10) can increase the height of the virtual scaffold (4a) three times in a unit size (1 m), thereby increasing the height of the virtual scaffold (4a) by 3 m. The unit size can be changed according to the user's setting. The processor (10) can reflect in real time the length, width, and height of the changed virtual scaffold (4a) in the input space (D2) that displays them as numbers.

[0139] FIG. 13 is a drawing showing a position adjustment step and a rotation adjustment step in a virtual ladder installation mode according to one embodiment.

[0140] The position adjustment step (S36b) is a step in which the user touches and drags the virtual scaffold (4a), which is an augmented reality object displayed on the display (41), to move the position of the virtual scaffold (4a). When the user touches the virtual scaffold (4a) in the position adjustment step (S36b), the processor (10) can display an outline (OL) of the virtual scaffold (4a). When the outline (OL) of the virtual scaffold (4a) is displayed, the user can recognize that the virtual scaffold (4a) has been selected. When the outline (OL) of the virtual scaffold (4a) is displayed, the user can touch (T1) the virtual scaffold (4a) with one finger and drag it in a desired direction. The processor (10) can move and display the virtual scaffold (4a) on the field image according to the direction and distance dragged by the user.

[0141] The user can compare the on-site situation (3) shown in the on-site image with the virtual scaffold (4a), which is an augmented reality object, to adjust the position of the virtual scaffold (4a) and position the virtual scaffold (4a) at a desired location.

[0142] The rotation control step (S36c) is a step in which the user touches and drags the virtual scaffold (4a), which is an augmented reality object displayed on the display (41), to rotate the virtual scaffold (4a). When the user touches the virtual scaffold (4a) in the rotation control step (S36c), the processor (10) can display an outline (OL) of the virtual scaffold (4a). The rotation control step (S36c) can be performed while the virtual scaffold (4a) is touched in the position control step (S36b). When the outline (OL) of the virtual scaffold (4a) is displayed, the user can recognize that the virtual scaffold (4a) has been selected. When the outline (OL) of the virtual scaffold (4a) is displayed, the user can touch (T2) the virtual scaffold (4a) with two fingers and drag it in a desired rotation direction. The processor (10) can rotate and display the virtual scaffold (4a) on the field image according to the direction and distance dragged by the user. The virtual scaffold (4a) can rotate about an axis perpendicular to the ground (5). The processor (10) can move the position of the virtual scaffold (4a) when a drag is input in a state where there is one touch point (one finger, T1), and can rotate the virtual scaffold (4a) when a drag is input in a state where there are two touch points (two fingers, T2).

[0143] The user can compare the on-site situation (3) shown in the on-site image with the virtual scaffold (4a), which is an augmented reality object, and rotate the virtual scaffold (4a) to adjust the virtual scaffold (4a) in the desired direction.

[0144] FIG. 14 is a diagram showing a locking movement step in a virtual ladder installation mode according to one embodiment.

[0145] The lock movement step (S36d) is a step of moving the virtual scaffold (4a) while the function of selecting the virtual scaffold (4a) is locked. In the lock movement step (S36d), the operation interface may provide a lock button (B17), an unlock button (B18), and a direction button (B19) provided when the lock button is activated. When the lock button (B17) is selected, input by selecting and dragging the virtual scaffold (4a) is restricted. When the lock button (B17) is selected, even if the user selects the virtual scaffold (4a), the outline (OL) is not displayed, and the scaffold does not move or rotate in the dragging direction. When the user selects the virtual scaffold (4a) while the lock button (B17) is activated, a pop-up window (not shown) including a guidance message indicating that the scaffold cannot be operated by touching it in the locked state may be provided. The pop-up window may disappear after a set period of time.

[0146] When the unlock button (B18) is selected, a position adjustment step (S36b) and a rotation adjustment step (S36c) can be performed by inputting a method of selecting and dragging a virtual ladder (4a).

[0147] The direction buttons (B19) provided when the lock button (B17) is activated may include an up button (B19U), a down button (B19D), a left button (B19L), and a right button (B19R). When the activated direction button (B19) is selected, the virtual scaffold (4a) can be moved in the selected direction. The user can select the lock button (B17) and the direction button (B19) to move the virtual scaffold (4a) in the desired direction by a set distance. The up, down, left, and right of the direction buttons (B19) may be directions on the ground (5) plane. The distance moved each time the direction button (B19) is selected may change according to the settings. When the direction button (B19) is selected once, the virtual scaffold (4a) can be moved by a set unit distance (e.g., 1 m).

[0148] Fig. 16 is a drawing showing a step of determining the structure of a virtual ladder (4a) in a virtual ladder installation mode according to one embodiment.

[0149] The step (S37) of confirming the virtual scaffold (4a) is a step of finally confirming the structure of the scaffold after the user has set the virtual scaffold (4a) to the desired type, size, location, and direction. In the step (S37) of confirming the virtual scaffold (4a), the work interface may provide a confirmation button (B20). The work interface may include a revert button (B21). When the revert button (B21) is selected, the processor (10) may cancel the size adjustment, location adjustment, and rotation adjustment of the virtual scaffold (4a) performed immediately before and return to the previous state. The user may check the adjusted length, width, and height in the input space (D2) indicating the size of the virtual scaffold (4a) and select the confirmation button (B20). When the user selects the confirmation button (B20), the processor (10) may confirm the structure of the virtual scaffold (4a) input by the user and take a picture of the virtual scaffold (4a).

[0150] Fig. 17 is a drawing showing a step of photographing a virtual ladder (4a) in a virtual ladder installation mode according to one embodiment.

[0151] The step of photographing the virtual scaffold (4a) may be performed after the step of determining the structure of the virtual scaffold (4a) (S37). Alternatively, the step of photographing the virtual scaffold (4a) may be performed by the user selecting a button to enter the photographing mode.

[0152] The step of photographing the virtual scaffold (4a) is a step of creating an image in which the virtual scaffold (4a), which is an augmented reality object, is overlapped with the on-site image. In the step of photographing the virtual scaffold (4a), the work interface may only provide a photograph button (B22). The work interface may display an explanatory message (M2) instructing the user to photograph the work content. The user may check the on-site (3) and the virtual scaffold (4a) displayed on the display (41) and select the photograph button (B22) to photograph the virtual scaffold (4a). The photo of the virtual scaffold (4a) may be included in the quantity calculation results.

[0153] When the scaffold input step (S30) is performed, a quantity calculation step (S50) for calculating the quantity of materials used in the scaffold based on the structure of the input scaffold can be performed.

[0154] Fig. 18 is a flowchart showing each step of the quantity calculation step (S50) according to one embodiment.

[0155] The quantity calculation step (S50) is a step for calculating the quantity of materials used in the scaffolding based on the structure of the input scaffolding. The quantity calculation step (S50) can calculate the quantity of the virtual scaffolding (4a) and the quantity of the on-site scaffolding (4b) in the same manner. The quantity calculation step (S50) may include a counting step (S51) for counting the quantity of materials required to install the scaffolding based on the structure of the scaffolding, a quantity calculation result display step (S52) for displaying the structure of the scaffolding and the quantity of the materials, and a summing step (S53) for selecting and summing multiple quantity calculation results that require summing.

[0156] And, the processor (10) counts the quantity of materials required to install the scaffold based on the structure of the scaffold in order to calculate the quantity of materials required for the structure of the scaffold, displays the structure of the scaffold and the quantity of materials, and provides a work interface for selecting and adding up multiple quantity calculation results that require summing, so that the quantity calculation results selected by the user can be added up.

[0157] The counting step (S51) can calculate the quantity of materials used to install the input scaffolding according to a preset scaffolding quantity calculation standard. Here, the scaffolding can include a virtual scaffolding (4a) and an on-site scaffolding (4b). In the counting step (S51), the processor (10) can calculate the quantity of materials required to install the scaffolding by applying the preset scaffolding quantity calculation standard to the structure of the input scaffolding. The counting step (S51) can be performed without user input when the scaffolding input step (S30) is completed. The quantity of materials calculated in the counting step (S51) can be displayed in the work details. The quantity of materials can be expressed as the number of installations, premium (height / width), and total.

[0158] The quantity calculation result display step (S52) is a step of displaying the quantity of materials calculated in the counting step on the display (41). In the quantity calculation result display step (S52), the processor (10) can reflect the calculated quantity of materials in the work details and display it on the display (41).

[0159] Fig. 19 is a drawing showing a work history interface provided when the structure input of a virtual scaffold (4a) is completed in a virtual scaffold installation mode according to one embodiment. See also Fig. 18.

[0160] Fig. 19 and Fig. 7 are the same work history interfaces. Since Fig. 19 shows a state in which the structure of the virtual scaffold (4a) has been input, it can be confirmed that the work history (R1) of the virtual scaffold (4a) displayed in the list (C3) exists. The work history (R1) registered in the list may include the name of the virtual scaffold (4a), a photo of the virtual scaffold (4a), length, width, height, number of installations, surcharge (height / width), total, and a transmit button (B23). The material quantity calculation result display step (S52) may be performed in a form in which the material quantity calculated in the count step (S51) is included in the work history and displayed on the display (41).

[0161] A user can select the Add button (B3) to open a work interface for entering a new virtual scaffold (4a). The newly added virtual scaffold (4a) can be entered according to the scaffold entry step (S30) performed in the virtual scaffold installation mode described above.

[0162] A user can delete an input virtual ladder (4a) by selecting a registered task (R1) in the list and selecting the delete button (B4). When the user selects a task (R1), the processor (10) can activate the delete button (B4). When the task (R1) is not selected, the delete button (B4) may be inactive. When the user selects the activated delete button (B4), the processor (10) may ask whether to delete the selected task (R1) through a pop-up window (not shown) and provide a Yes button or a No button. When the user selects the Yes button, the processor (10) can delete the selected task (R1).

[0163] A user can transmit the work history (R1) to the remote management system (2) by selecting the transmit button (B23) of the work history (R1). The transmit button (B23) of the work history (R1) transmitted to the remote management system (2) may be disabled.

[0164] The work history (R1) transmitted to the remote management system (2) can be stored in the remote management system (2). The remote management system (2) can organize the transmitted work history (R1) into a pre-stored report and output it. The report is stored in the remote management system (2), and the location where the data included in the work history (R1) is to be inserted into the report is determined. The report can include a photograph of the scaffold and data on the structure of the scaffold. The report can be checked on the web when connected to the remote management system (2), and can be downloaded as a PDF file or a spreadsheet file.

[0165] An enterprise resource planning system (ERP) connected to a remote management system (2) can receive work history stored in the remote management system (2) and use it as a basis for payment of installation costs to be provided to a scaffolding installation company.

[0166] FIG. 20 is a diagram illustrating a summation function in a virtual ladder installation mode according to one embodiment. See also FIG. 18.

[0167] The merge step (S53) is a step of merged the results of calculating the quantity of the work history (R1) to be merged among the multiple work histories (R1) displayed in the list of the work history interface. In the merge step (S53), the work interface may provide a merge button (B24). The merge button (B24) may not be activated if any of the work histories (R1, R2) displayed in the work history list (C3) has not been transmitted. If the user selects the merge button (B24) when any of the work histories (R1, R2) displayed in the work history list (C3) has not been transmitted, a pop-up window (not shown) may be displayed, and the pop-up window may include an explanation that merge is possible if all work histories included in the work history list (C3) have been transmitted.

[0168] The sum button (B24) can be activated by the user's selection when all the work histories (R1, R2) displayed in the work history list (C3) are transmitted. When the sum button (B24) is activated, the processor (10) can add up the material quantities of the work histories (R1, R2) displayed in the work history list (C3) and display them as numbers in the grand total (C4). When the sum button (B24) is activated, adding or deleting work histories (R1, R2) can be restricted. When the sum button (B24) is activated, the add button (B3) and the delete button (B4) can be deactivated. When the sum button (B24) is activated, information that the work histories (R1, R2) included in the work history list (C3) are summed data can be provided to the remote management system (2).

[0169] The user can deactivate the Sum button (B24) by re-selecting the activated Sum button (B24). When the Sum button (B24) is deactivated, the Add button (B3) can be activated, allowing the user to select the work history (R1, R2). When the Sum button (B24) is deactivated, information can be provided to the remote management system (2) that the sum of the work history (R1, R2) included in the work history list (C3) has been deactivated.

[0170] A method for verifying scaffolding material quantities using augmented reality according to one embodiment can be used to calculate the quantity of materials used for scaffolding installation based on the scaffold's structure. Even when multiple scaffolds are installed, the quantity can be calculated and confirmed by adding them together. Therefore, compared to manual scaffolding quantity calculations, this method enables faster and more accurate material calculations.

[0171] Figure 21 is a drawing explaining a standard for calculating the amount of ladder material according to one embodiment.

[0172] The scaffolding material quantity calculation standard is used to calculate the material quantity for a virtual scaffold (4a) or an on-site scaffold (4b). The scaffolding material quantity calculation standard can be applied equally to both a virtual scaffold (4a) and an on-site scaffold (4b). The scaffolding material quantity calculation standard may vary depending on the scaffolding installation company.

[0173] The scaffolding quantity calculation standard can be determined using the length (L), width (W), and height (H). For example, the scaffolding quantity calculation standard can calculate the outer twine area by multiplying the length (L) by the height (H), and if the width (W) exceeds 2 m, the scaffolding area can be calculated by adding 50% of the outer twine area for every 2 m. At this time, the length (L), width (W), and height (H) of the scaffold can be measured based on the end of the scaffold. The specific scaffolding quantity calculation standard may vary depending on the scaffolding installation company. The scaffolding quantity calculation standard can be stored in the storage unit (20). The processor (10) can analyze the structure of the scaffold in the counting step (S51) according to the scaffolding quantity calculation standard and count the quantity of materials required for the installation of the scaffold.

[0174] The scaffolding quantity calculation criteria can vary depending on the type of scaffolding, the company installing the scaffolding, and legal requirements. These criteria may vary depending on the site (3) where the scaffolding will be installed. Users can select the scaffolding quantity calculation criteria applicable to their site (3).

[0175] Figure 22 is a drawing explaining a high-altitude surcharge among the standards for calculating the amount of ladder material according to one embodiment.

[0176] The height surcharge is one of the criteria for calculating scaffolding volume. The height surcharge may be applied to scaffolding exceeding a specified height or width. Additional costs may be incurred for the portion of the scaffolding subject to the height surcharge.

[0177] For example, in the case of scaffolding with a high height (H) installed around a tall structure (such as a chimney or tower), a height surcharge may be applied. The height surcharge may be determined as 0% for scaffolding heights less than 10 m, 10% for scaffolding heights of 10 m to 20 m, 20% for scaffolding heights of 20 m to 30 m, 30% for scaffolding heights of 30 m to 50 m, 40% for scaffolding heights of 50 m to 60 m, and 10% for each 10 m increase for scaffolding heights of 60 m or more. If a height surcharge is applied, the installation cost due to the height surcharge may be additionally added when calculating the scaffolding area.

[0178] Similarly, for scaffolds with a wide width (W), a height surcharge may be applied. The height surcharge may add an additional cost proportional to the width of the scaffold.

[0179] Therefore, the cost of installing the scaffolding may increase depending on the surcharge.

[0180] In one embodiment, the counting step can calculate the installation cost based on the quantity of materials by reflecting the stored surcharge. The surcharge can be determined by the contractor requesting the scaffolding installation. The counting step calculates the quantity of materials used for the scaffolding, and then applies the surcharge to calculate the final installation cost. The installation cost can be calculated in monetary terms.

[0181] The high-altitude surcharge may be set differently for each company requesting the installation of the scaffold. The processor (10) may perform the counting step by applying the high-altitude surcharge determined and stored by the company requesting the installation of the scaffold.

[0182] Users can select one of multiple surcharges stored in the storage. The storage can store multiple surcharge data determined by multiple companies. Companies requesting scaffolding installation can store multiple surcharges in the storage to apply different surcharges to each business location. Alternatively, there may be multiple companies requesting scaffolding installation. For example, if multiple companies are grouped as affiliates, each company within the group can determine a different surcharge.

[0183] FIG. 22 is a drawing showing the basic interface displayed when the work history window is closed in a virtual ladder installation mode according to one embodiment.

[0184] The basic interface can display a scaffolding installation button (B25) and a work history button (B26) at the edge of the display (41). The basic interface can display a tool button (B27) that performs the function of displaying or hiding the scaffolding installation button (B25) and the work history button (B26). When the tool button (B27) is selected while the scaffolding installation button (B25) and the work history button (B26) are displayed, the scaffolding installation button (B25) and the work history button (B26) can be changed to a hidden state. In the hidden state, only the tool button (B27) can be displayed. When the tool button (B27) is selected while the scaffolding installation button (B25) and the work history button (B26) are hidden, the scaffolding installation button (B25) and the work history button (B26) can be displayed.

[0185] When the ladder installation button (B25) is selected, the ladder input step (S30) in the virtual ladder installation mode described above can be performed to input the structure of a new virtual ladder (4a).

[0186] When the Work History button (B26) is selected, a work history interface displaying the work history list (C3) described in FIGS. 19 and 20 may be displayed.

[0187] FIG. 24 is a drawing showing a work interface for checking the structure of a scaffold entered in work history in a virtual scaffold installation mode according to one embodiment.

[0188] When measurement data (length, width, height, etc.) is selected in the work history (R1) of the work history interface described in Fig. 19, the augmented reality object of the virtual scaffold (4a) may be displayed on the display (41), and the size of the virtual scaffold (4a) may be displayed on the display (41). The work interface for confirming the structure of the scaffold may include a modification button (B28) and a delete button (B29). When the modification button (B28) is selected, the processor (10) may display a work interface capable of modifying the size described with reference to Fig. 13. The user may modify the size of the virtual scaffold (4a) and select the confirmation button to modify and input the size of the scaffold. When the delete button (B29) is selected, the processor (10) may provide a Yes button or a No button in a pop-up window (not shown) to select whether to delete the corresponding virtual scaffold (4a). If the user selects the Yes button, the corresponding task history will be deleted, and if the user selects the No button, the pop-up window will disappear and the user can return to the task interface where the structure of the ladder entered in the task history can be confirmed.

[0189] Through the described process, the structure of the virtual scaffold (4a) can be input, and the quantity and installation cost of materials required for scaffold installation can be calculated based on the structure of the virtual scaffold (4a) to generate a quantity calculation result, multiple quantity calculation results can be added, and the quantity calculation result can also be transmitted to the remote management system (2).

[0190] FIG. 25 is a diagram showing a work history interface provided when selecting a field scaffold measurement mode according to one embodiment.

[0191] When the user selects the on-site scaffold measurement mode in the mode selection step (S20) described with reference to FIG. 6, the processor (10) can display the on-site scaffold measurement details interface as a pop-up window on the display (41).

[0192] The on-site scaffolding measurement history interface may have the same functionality as the virtual scaffolding installation history interface described with reference to FIG. 7. The on-site scaffolding measurement history interface may be the initial screen entered when the on-site scaffolding measurement mode is selected. The on-site scaffolding measurement history interface may display the job number (C1) and job name (C2) of the work performed in the on-site scaffolding measurement mode. The job number may be displayed with 3 digits or less. The job name may be entered with 64 characters or less, and up to 16 characters may be displayed on the work interface. The on-site scaffolding measurement history interface may display a list (C3) of the on-site scaffolding measurement work performed. The on-site scaffolding measurement history interface may include an Add button (B3) for adding a work, and a Delete button (B4) for deleting a work. Selecting the Add button (B3) may create a new on-site scaffolding measurement work. When a new on-site scaffolding measurement work is created, a pop-up window for entering a scaffolding name may be displayed. The selected field scaffolding measurement work history can be deleted by selecting the field scaffolding measurement work history displayed in the list (C3) and pressing the delete button (B4).

[0193] Fig. 26 is a flowchart showing each step of a method for verifying scaffold quantity using augmented reality performed in a field scaffold measurement mode according to one embodiment.

[0194] The scaffold input step (S30) performed in the field scaffold measurement mode is a step of inputting the structure of the scaffold installed on site (3).

[0195] In the field scaffold measurement mode, the scaffold input step (S30) may include a step (S38) of recognizing the ground (5) on which the field scaffold (4b) is installed, a step (S39) of selecting a point of the field scaffold (4b) displayed on the display (41) to measure the size of the field scaffold (4b), and a step (S40) of determining the structure of the field scaffold (4b).

[0196] The processor (10) provides a work interface for recognizing the ground (5) on which the field scaffold (4b) is installed in order to input the structure of the scaffold in the field scaffold measurement mode, provides a work interface for measuring the size of the field scaffold (4b) by selecting a point of the field scaffold (4b) displayed on the display (41), and can perform an operation for determining the structure of the virtual scaffold (4a) based on the user's input.

[0197] The ground recognition step (S38) for recognizing the ground (5) on which the field scaffold (4b) is installed can be performed while the user points the camera (31) toward the area where the field scaffold (4b) is installed. In the ground (5) recognition step (S38), the processor (10) can recognize the ground (5) that serves as a reference for measuring the size of the field scaffold (4b). The ground recognition step (S38) of the field scaffold measurement mode and the ground recognition step (S31) of the virtual scaffold installation mode are substantially similar.

[0198] The step (S39) of measuring the size of the on-site scaffold (4b) is a step of entering the size of the on-site scaffold (4b) by taking a picture of the scaffold installed on the site (3) with a camera (31) and displaying it on the display (41), selecting multiple points of the on-site scaffold (4b) displayed on the display (41), and adjusting the size of lines, planes, and cubes (CB), which are augmented reality objects formed by connecting the points, to match the on-site scaffold (4b) displayed on the display (41). The step of confirming the structure of the on-site scaffold (4b) is a step of confirming whether the size of the on-site scaffold (4b) and the augmented reality object appearing in the on-site image match, and determining to input the size of the augmented reality object as the size of the on-site scaffold (4b).

[0199] In the field scaffold measurement mode, the scaffold input step (S30) allows the user to measure the size of the field scaffold (4b) by matching the size of the cube (CB), which is an augmented reality object, to the field scaffold (4b) appearing in the field image, so that the size of the field scaffold (4b) can be conveniently and easily input.

[0200] The step (S39) of measuring the size of the field scaffold (4b) is as follows: when the center pointer (CP) is created in the center of the display (41), the center pointer (CP) is positioned at the first vertex of the bottom surface (BS) of the field scaffold (4b) to select the first point (P1), and when a line extending from the first point (P1) to the center pointer (CP) is displayed on the display (41), the center pointer (CP) is positioned at the second vertex of the bottom surface (BS) of the field scaffold (4b) to select the second point (P2), and the length measuring step (S39a) of calculating the length from the first point (P1) to the second point (P2), and when a surface extending from the line connecting the first point (P1) and the second point (P2) to the center pointer (CP) is displayed on the display (41), the center pointer (CP) is positioned at the third vertex of the bottom surface (BS) of the field scaffold (4b) to select the third point (P3), and the first It may include a width measuring step (S39b) for calculating the width from the line connecting the point (P1) and the second point (P2) to the third point (P3), a cube (CB) of a predetermined height perpendicular to the plane where the first point (P1), the second point (P2), and the third point (P3) are located is displayed on the display (41), a height increasing button or a height decreasing button displayed on the display (41) is selected to match the height of the cube (CB) displayed on the display (41) with the field scaffold (4b), and a height measuring step (S39c) for determining the height of the cube (CB) as the height of the field scaffold (4b).

[0201] In order to measure the size of the field scaffold (4b), the processor (10) selects the first point (P1) by positioning the center pointer (CP) at the first vertex of the bottom surface (BS) of the field scaffold (4b) when the center pointer (CP) is generated at the center of the display (41), and a line extending from the first point (P1) to the center pointer (CP) is displayed on the display (41), and a second point (P2) is selected by positioning the center pointer (CP) at the second vertex of the bottom surface (BS) of the field scaffold (4b), and a length measuring operation for calculating the length from the first point (P1) to the second point (P2), and a surface where the line from the first point (P1) to the second point (P2) extends to the center pointer (CP) is displayed on the display (41), and a third point (P3) is selected by positioning the center pointer (CP) at the third vertex of the bottom surface (BS) of the field scaffold (4b), and a length measuring operation for calculating the length from the first point (P1) to the second point (P2) is displayed on the display (41). A width measurement operation for calculating the width from a line connecting a second point (P2) to a third point (P3), a cube (CB) of a predetermined height perpendicular to the plane where the first point (P1), the second point (P2), and the third point (P3) are located is displayed on the display (41), and a height measurement operation for matching the height of the cube (CB) displayed on the display (41) with the field scaffold (4b) by selecting a height increase button or a height decrease button displayed on the display (41), and determining the height of the cube (CB) as the height of the field scaffold (4b) can be performed.

[0202] Fig. 27 is a drawing explaining a step of recognizing the ground (5) in a field ladder measurement mode according to one embodiment.

[0203] When a new field scaffold (4b) measurement task starts in the field scaffold measurement mode, a step (S38) of recognizing the ground (5) may be performed first. The step (S38) of recognizing the ground (5) is a step of determining the ground (5) (ground) at the location where the field scaffold (4b) is installed. In the step (S38) of recognizing the ground (5), the processor (10) may display a field image generated by the camera (31) by photographing the field (3) in real time on the display (41). In the step (S38) of recognizing the ground (5), the work interface may provide a frame (F1) in the form of a picture frame and a guidance message (M1). The guidance message (M1) may include a method for the user to recognize the ground (5) by adjusting the camera (31). The guidance message may disappear after a predetermined time (e.g., 5 seconds). The user can adjust the camera (31) so that a portion of the ground (5) where the field scaffolding (4b) is installed is located within a frame (F1) in the form of a picture frame. Selecting the back button (B5) returns to the mode selection step (S20).

[0204] When a predetermined time has elapsed while the user adjusts the camera (31) to capture a location where the field scaffold (4b) is installed, the processor (10) can recognize the location where the field scaffold (4b) is installed based on the measurement value received from the sensor unit (30) and the field image captured by the camera (31). When the location where the scaffold is installed is recognized, the processor (10) can display a pop-up window indicating that ground recognition is complete on the display (41). The pop-up window disappears when the predetermined time has elapsed, and the scaffold size measurement step (S39) can be performed. In the scaffold size measurement step (S39), the length measurement step (S39a) can be performed first.

[0205] Fig. 28 is a flowchart illustrating a length measurement step (S39a) in a field scaffold measurement mode according to one embodiment. Fig. 29 is a diagram illustrating a state in which a central pointer (CP) is generated in the length measurement step (S39a) according to one embodiment.

[0206] When the length measurement step (S39a) starts, a work interface for measuring the size of the field scaffolding (4b) can be displayed on the display (41). The work interface can include an input space (D3) corresponding to length, width, and height, a guide (M3) explaining that it is a step for measuring length, a confirmation button (B30), and a center pointer (CP). The input space corresponding to the length can calculate and display the length of a line, which is an augmented reality object appearing on the display (41), as a real length, and the input space corresponding to the width can calculate and display the width of a plane, which is an augmented reality object appearing on the display (41), as a real width, and the input space corresponding to the height can calculate and display the height of a cube (CB), which is an augmented reality object appearing on the display (41), as a real height.

[0207] The length measuring step (S39a) may include a step (S39a1) of creating a center pointer (CP) in the center of the display (41), a step (S39a2) of selecting a first point (P1) by positioning the center pointer (CP) at the first vertex of the bottom surface (BS) of the field scaffold (4b), a step (S39a3) of displaying a line extending from the first point (P1) to the center pointer (CP) on the display (41), a step (S39a4) of selecting a second point (P2) by positioning the center pointer (CP) at the second vertex of the bottom surface (BS) of the field scaffold (4b), and a step (S39a5) of calculating a length from the first point (P1) to the second point (P2).

[0208] As illustrated in FIG. 29, when the step (S39a1) of generating a central pointer (CP) is performed, the central pointer (CP) can be generated at the center of the display (41). The central pointer (CP) is a mark displayed at the center of the screen of the display (41). The central pointer (CP) can be displayed at the center of the screen of the display (41) even if the user changes the direction of the camera (31). The user can move the camera (31) so that the central pointer (CP) aligns with one of the plurality of vertices constituting the bottom surface (BS) of the field scaffold (4b). The bottom surface (BS) of the field scaffold (4b) is indicated by hatching in FIG. 29.

[0209] In the step (S39a2) of selecting the first point (P1), when the user positions the central pointer (CP) at the first vertex (BS) of the bottom surface (BS) of the field scaffold (4b) and selects the confirmation button (B30), the first point (P1) can be selected. The first point (P1) can be selected as a position that matches the first vertex of the bottom surface (BS) of the field scaffold (4b). The processor (10) can recognize which position the central pointer (CP) indicates on the field (3) based on the recognized position of the ground (5), the measurement value measured by the sensor unit (30), and the direction of the camera (31), and when the confirmation button (B30) is selected, the point indicated by the central pointer (CP) on the field (3) can be recognized as the first point (P1). The processor (10) can calculate which position the first point (P1) corresponds to on the field (3).

[0210] FIG. 30 is a drawing showing a state in which a line (LN) is created from a first point (P1) to a center pointer (CP) in a length measurement step (S39a) according to one embodiment.

[0211] The step (S39a3) of displaying a line on the display (41) can be performed when the first point (P1) is selected. In the step (S39a3) of displaying a line (LN) on the display (41), the processor (10) can generate a line (LN), which is an augmented reality object connecting the first point (P1) to the central pointer (CP), and display the line (LN) on the display (41). When the user changes the direction of the camera (31) and the position of the scene (3) pointed to by the central pointer (CP) changes, the length and position of the line (LN), which is an augmented reality object connecting the first point (P1) to the central pointer (CP), can also be changed.

[0212] In the step (S39a4) of selecting the second point (P2), the user can align the central pointer (CP) with the second vertex located longitudinally from the first vertex of the bottom surface (BS) of the field scaffold (4b) and select the confirmation button (B30). The distance between the first vertex and the second vertex may be the length of the field scaffold (4b). When the user selects the confirmation button (B30), the processor (10) can recognize the position of the central pointer (CP) as the second point (P2).

[0213] Fig. 31 is a drawing showing a state in which a second point (P2) is selected in a length measurement step (S39a) according to one embodiment.

[0214] When the second point (P2) is selected, a step (S39a5) of calculating a length from the first point (P1) to the second point (P2) can be performed. The line (LN) connecting the first point (P1) to the second point (P2) corresponds to the length of the field scaffold (4b), and the processor (10) can calculate the distance between the location of the field (3) indicated by the first point (P1) and the location of the field (3) indicated by the second point (P2), and display it in the input space (D3) corresponding to the length of the field scaffold (4b).

[0215] When the length measurement step (S39a) of the field scaffold (4b) is completed, the width measurement step (S39b) of the field scaffold (4b) can be performed. Since the length measurement of the field scaffold (4b) is completed, the processor (10) can display a message (M4) on the display (41) to measure the width.

[0216] Fig. 32 is a flowchart illustrating a width measurement step (S39b) in a field scaffold measurement mode according to one embodiment. Fig. 33 is a diagram illustrating a state in which a surface is created from a line (LN) to a center pointer (CP) in a field scaffold measurement mode according to one embodiment.

[0217] The width measurement step (S39b) may be performed after the length measurement step (S39a) is performed. The work interface provided in the width measurement step (S39b) is identical to the work interface provided in the length measurement step (S39a).

[0218] The width measurement step (S39b) may include a step (S39b1) in which a surface (PL) extending from a line (LN) from a first point (P1) to a second point (P2) to a center pointer (CP) is displayed on a display (41), a step (S39b2) in which the center pointer (CP) is positioned at the third vertex of the bottom surface (BS) of the field scaffold (4b) to select a third point (P3), and a step (S39b3) in which the width from a line (LN) connecting the first point (P1) to the second point (P2) to the third point (P3) is calculated.

[0219] The width measurement step (S39b) can be performed based on the length measured in the length measurement step (S39a). In the width measurement step (S39b), the processor (10) displays a plane (PL), which is an augmented reality object, whose width is a vertical line from a line (LN) connecting the first point (P1) and the second point (P2) to the center pointer (CP), on the display (41), and the user can measure the width of the field scaffold (4b) by aligning the center pointer (CP) with the third vertex of the bottom surface (BS) of the actual scaffold.

[0220] In the step (S39b1) where a surface (PL) is displayed on the display (41), the processor (10) can generate a surface (PL), which is an augmented reality object connecting a central pointer (CP) to a line (LN), and display the surface (PL) on the display (41). The line (LN) connects a first point (P1) and a second point (P2) and is fixed to a location on the scene (3). When a user moves the camera (31), a rectangular augmented reality object (PL) can be generated from the line (LN) to the central pointer (CP).

[0221] Fig. 34 is a drawing showing a state in which a third point (P3) is selected in a field ladder measurement mode according to one embodiment.

[0222] In the step (S39b2) of selecting the third point (P3), the user can position the central pointer (CP) at the third vertex of the bottom surface (BS) of the field scaffold (4b) and select the confirmation button. When the confirmation button (B30) is selected, the processor (10) can recognize the location of the field (3) pointed to by the central pointer (CP) as the third point (P3). The processor (10) can calculate the distance of the shortest straight line connecting the line (LN) to the third point (P3) and recognize it as the width of the field scaffold (4b). The processor (10) can display the calculated distance in the input space (D4) corresponding to the width.

[0223] Fig. 35 is a flowchart illustrating a height measurement step (S39c) in a field scaffold measurement mode according to one embodiment. Fig. 36 is a diagram illustrating a state in which an augmented reality object, a cube (CB), is created in a field scaffold measurement mode according to one embodiment.

[0224] The height measurement step (S39c) may include a step (S39c1) of displaying a cube (CB) of a predetermined height perpendicular to the plane (PL) where the first point (P1), the second point (P2), and the third point (P3) are located on the display (41), a step (S39c2) of matching the height of the cube (CB) displayed on the display (41) with the on-site scaffold (4b) by selecting a height increase button (B31) or a height decrease button (B32) displayed on the display (41), and a step (S39c3) of determining the height of the cube (CB) as the height of the on-site scaffold (4b).

[0225] The height measurement step (S39c) may be performed after the width measurement step (S39b) is performed. The height measurement step (S39c) generates a cube (CB), which is an augmented reality object, based on the line (LN) determined in the length measurement step (S39a) and the surface (PL) determined in the width measurement step (S39b), and displays the cube (CB) on the display (41). The user adjusts the height of the cube (CB) displayed on the display (41) so that the height matches the field scaffold (4b) of the field image. The processor (10) may calculate a height converted from the height of the cube (CB) to a height in reality, and determine the calculated height as the height of the field scaffold (4b).

[0226] In the step (S39c1) where the cube (CB) is displayed on the display (41), the processor (10) can generate a cube (CB), which is an augmented reality object, having a base surface (PL) determined in the width measurement step (S39b) and a set height, and display the cube (CB) on the display (41). The cube (CB) can be displayed at a position that matches the base surface (BS) of the field scaffolding (4b) appearing in the field image. The height of the cube (CB) can be a preset height (e.g., 1 m).

[0227] The work interface may include a height increase button (B31) and a height decrease button (B32). When the height increase button (B31) is selected, the processor (10) may increase the height of the cube (CB) by a predetermined unit height and display it on the display (41). When the height decrease button (B32) is selected, the processor (10) may decrease the height of the cube (CB) by a predetermined unit height and display it on the display (41).

[0228] Fig. 37 is a drawing showing a state in which the height of the cube (CB) is adjusted to match the height of the field scaffold (4b) in the field scaffold measurement mode according to one embodiment.

[0229] In the step of matching the height of the cube (CB) with the field scaffold (4b), the user can select the height increase button (B31) and the height decrease button (B32) to adjust the height of the cube (CB), which is an augmented reality object displayed on the display (41), to match the height of the field scaffold (4b) appearing in the field image, and then select the confirmation button (B30). When the height increase button (B31) or the height decrease button (B32) is selected, the processor (10) changes the height of the cube (CB) by a unit height. However, since the unit height is a real height, the processor (10) can adjust and increase the height of the cube (CB), which is an augmented reality object, by using the measurement values ​​of the sensors received from the measuring unit, the recognized position of the ground (5), the direction of the camera (31), etc. The size input space (D5) can display the height being adjusted in real time. The user can select the confirmation button (B30) when the height of the cube (CB), which is an augmented reality object, matches the height of the real scaffold appearing in the real image.

[0230] When the confirmation button (B30) is selected, a step (S39c3) of determining the height of the cube (CB) as the height of the field scaffold (4b) is performed, and the processor (10) can determine the height of the cube (CB) as the height of the field scaffold (4b). When the confirmation button (B30) is selected and the processor (10) determines the height of the cube (CB) as the height of the field scaffold (4b), a step (S40) of determining the structure of the field scaffold (4b) can be performed. The step (S40) of determining the structure of the field scaffold (4b) is a step of determining the length, width, and height of the field scaffold (4b) measured by the user as the structure of the field scaffold (4b). When the user selects the confirmation button (B30), the processor (10) can determine the structure of the field scaffold (4b) measured by the user and take a picture of the field scaffold (4b).

[0231] Fig. 38 is a drawing showing a step of photographing a field scaffold (4b) in a field scaffold measurement mode according to one embodiment.

[0232] The step of photographing the on-site scaffold (4b) may be performed after the step of determining the structure of the on-site scaffold (4b) (S40). Alternatively, the step of photographing the on-site scaffold (4b) may be performed by the user selecting a button to enter the photographing mode.

[0233] The step of photographing the on-site scaffold (4b) is a step of creating an image in which the augmented reality object, the cube (CB), overlaps the on-site scaffold (4b) in the on-site image. In the step of photographing the on-site scaffold (4b), the work interface may only provide a photograph button. The user can check the on-site scaffold (4b) and the cube (CB) displayed on the display (41) and select the photograph button (B33) to photograph the on-site scaffold (4b). The on-site scaffold (4b) photograph may be included in the quantity calculation results.

[0234] When the scaffold input step (S30) is fully performed, a quantity calculation step (S50) for calculating the quantity of materials used in the scaffolding based on the structure of the input scaffolding can be performed. The quantity calculation step (S50) in the field scaffolding measurement mode can be performed similarly to the quantity calculation step (S50) in the virtual scaffold (4a) measurement mode described with reference to FIGS. 17 to 21, and therefore a detailed description thereof will be omitted.

[0235] Fig. 39 is a diagram showing a work interface for confirming the structure of a scaffold entered in the work history in the field scaffold measurement mode according to one embodiment. Fig. 40 is a diagram showing a state in which an augmented reality object is displayed in scaffold mode in the field scaffold measurement mode according to one embodiment. Fig. 39 shows a state in which an augmented reality object is displayed in cube (CB) mode, and Fig. 40 shows a state in which an augmented reality object is displayed in scaffold mode.

[0236] A drawing showing a work interface for checking the structure of a scaffold entered in a work history in a field scaffold measurement mode according to one embodiment.

[0237] Similarly to Fig. 19, when the measurement data of the work history generated by measuring the actual scaffold is selected in the work history interface, the size of the field scaffold (4b) may be displayed on the display (41) while the cube (CB), which is an augmented reality object overlapped with the actual image. The work interface for checking the structure of the scaffold may include a cube (CB) button (B34) and a scaffold button (B35) for changing the display mode of the augmented reality cube (CB). When the user selects the cube (CB) button (B34) to activate the cube (CB) mode, the processor (10) may display the augmented reality object in the form of a translucent cube (CB). When the user selects the scaffold button (B35) to activate the scaffold mode, the processor (10) may display the cube (CB) as a three-dimensional scaffold image.

[0238] When the delete button (B36) is selected, the processor (10) may provide a Yes or No button in a pop-up window to select whether to delete the corresponding real-world scaffold. If the user selects the Yes button, the corresponding work history is deleted, and if the user selects the No button, the pop-up window disappears and the user returns to the work interface for confirming the structure of the scaffold entered in the work history.

[0239] Through the described process, the structure of an actual scaffold can be input, and the quantity and installation cost of materials required for scaffold installation can be calculated based on the structure of the actual scaffold to generate a quantity calculation result, multiple quantity calculation results can be added, and the quantity calculation result can also be transmitted to a remote management system (2).

[0240] Fig. 41 is a flowchart showing a step of measuring the size of a field scaffold (4b) located in the air and spaced apart from the ground (5) according to one embodiment.

[0241] Scaffolding can be installed in the air. An aerial scaffolding installed to float in the air by a building or other scaffolding is a structure in which the bottom surface (BS) of the scaffolding is not supported by the ground (5). An aerial scaffolding is also called a moon scaffolding. In order to measure the structure of an on-site scaffolding (4b) located in the air, a method for verifying the quantity of scaffolding using augmented reality according to an embodiment may include a step (S41) of recognizing the ground (5) located below the on-site scaffolding (4b) located in the air, a step (S42) of measuring the size of a modified on-site scaffolding (4b) to measure the size of a scaffold located in the air and spaced apart from the ground (5), and a step (S43) of determining the structure of the on-site scaffolding (4b).

[0242] According to one embodiment, the step (S42) of measuring the size of the field scaffold (4b) may be performed to measure the size of the field scaffold (4b) located in the air and spaced apart from the ground (5), and when the center pointer (CP) is created in the center of the display (41), the center pointer (CP) is positioned at the first vertex of the surface projected on the ground (5) of the bottom (BS) of the field scaffold (4b) located in the air to select the first point (P1), and when the line extending from the first point (P1) to the center pointer (CP) is displayed on the display (41), the second point (P2) is positioned at the second vertex of the surface projected, and the length measuring step (S42a) of calculating the length from the first point (P1) to the second point (P2), and the surface extending from the line connecting the first point (P1) and the second point (P2) to the center pointer (CP) is displayed on the display (41), and the center A width measurement step (S42b) of selecting a third point (P3) by positioning a pointer (CP) at the third vertex of a projected surface, and calculating the width from a line connecting the first point (P1) and the second point (P2) to the third point (P3), a cube (CB) display step (S42c) of displaying a cube (CB) of a predetermined height perpendicular to the surface where the first point (P1), the second point (P2), and the third point (P3) are located on a display (41), a position control step (S42d) of displaying a position control button for moving the position of the cube (CB) in the length, width, and height directions, a distance selection button for selecting a distance to be moved by selecting the position control button, and a rotation slide bar for rotating the cube (CB) on the display (41), and moving the cube (CB) to match a ladder positioned in the air using the position control button, the distance selection button, and the rotation slide bar,And it may include a size adjustment step (S42e) to match the size of the cube (CB) to a ladder positioned in the air by selecting a face button while selecting a size increase button or a size decrease button displayed on the display (41) to increase or decrease the size of the selected face.

[0243] In order to measure the size of a scaffold located in the air and spaced apart from the ground (5), the processor (10) selects the first point (P1) by positioning the central pointer (CP) at the first point (P1) corresponding to the first vertex of the surface projected on the ground (5) of the bottom (BS) of the scaffold located in the air when the central pointer (CP) is generated at the center of the display (41), and when a line extending from the first point (P1) to the central pointer (CP) is displayed on the display (41), the processor (10) selects the second point (P2) by positioning the central pointer (CP) at the second vertex of the surface projected, and calculates the length from the first point (P1) to the second point (P2), and when a surface on which the line from the first point (P1) to the second point (P2) extends to the central pointer (CP) is displayed on the display (41), the processor (10) selects the third point (P3) by positioning the central pointer (CP) at the third vertex of the surface projected, A width measurement operation for calculating the width from a line connecting a first point (P1) to a second point (P2) to a third point (P3), a cube (CB) display operation for displaying a cube (CB) of a set height perpendicular to the plane where the first point (P1), the second point (P2), and the third point (P3) are located on a display (41), a position control button for moving the position of the cube (CB) in the length, width, and height directions, a distance selection button for selecting a distance to be moved by selecting the position control button, and a rotation slide bar for rotating the cube (CB) are displayed on the display (41), and a position control operation for moving the cube (CB) to match a scaffold located in the air using the position control button, the distance selection button, and the rotation slide bar, and a size control operation for matching the size of the cube (CB) to the scaffold located in the air by selecting a size increase button or a size decrease button displayed on the display (41) and selecting a plane button to increase or decrease the size of the selected plane.

[0244] In order to measure the size of an aerial scaffold (4b) (hereinafter referred to as an "aerial scaffold") located in the air, the length and width of the approximate bottom (BS) of the aerial scaffold are input on the ground (5) where the bottom (BS) of the aerial scaffold is thought to be located when the bottom (BS) of the aerial scaffold is moved vertically downward, a cube (CB) of a set height is generated, and then the position of the cube (CB) is moved to the aerial scaffold and the size of the cube (CB) overlapped with the aerial scaffold is adjusted so that the cube (CB), which is an augmented reality object, matches the aerial scaffold, thereby allowing the size of the aerial scaffold to be measured.

[0245] Fig. 42 is a drawing showing a state of recognizing the ground (5) where the bottom surface (BS) of an aerial ladder according to one embodiment is expected to be located.

[0246] The working interface for recognizing the ground (5) and measuring the length and width may include an input space (D6) for displaying the length, width, height, width surcharge, height surcharge, and ground height, and a confirmation button (B37).

[0247] In the step (S41) of recognizing the ground (5), the user can position the camera (31) toward a part of the ground (5) where the aerial scaffold is expected to be located when the aerial scaffold is moved to the ground. If the camera (31) is maintained toward the same position for a predetermined period of time, the processor (10) can recognize the ground (5) by considering the measurement value of the sensor unit (30), the direction of the camera (31), etc.

[0248] When the ground (5) is recognized, a length measurement step (S42a) can be performed. The length measurement step (S42a) can be performed similarly to the contents described with reference to FIGS. 28 to 30. In the length measurement step (S42a), the processor (10) displays a center pointer (CP) at the center of the display (41), and the user can move the direction of the camera (31) to position the center pointer (CP) at a position corresponding to the first vertex of the surface projected with the bottom (BS) of the aerial scaffold onto the ground (5) and determine the first point (P1). Then, the user can move the direction of the camera (31), and the processor (10) can display a line (LN) connecting the first vertex to the center pointer (CP). The user can position the center pointer (CP) at a position corresponding to the second vertex of the surface projected with the bottom (BS) of the aerial scaffold onto the ground (5) and determine the second point (P2). Once the first point (P1) and the second point (P2) are determined, the processor (10) can calculate a length corresponding to the length of the line (LN) connecting the first point (P1) and the second point (P2).

[0249] FIG. 43 is a drawing showing a surface, which is an augmented reality object created to measure an aerial scaffold according to one embodiment. See also FIG. 42.

[0250] The width measurement step (S42b) may be performed after the length measurement step (S42a) is performed. In the width measurement step (S42b), the processor (10) may generate a rectangular surface (PL) whose width is the shortest distance from the line (LN) to the center pointer (CP), and display the generated rectangular surface (PL) on the display (41). The surface (PL), which is an augmented reality object, may be formed as a rectangle whose length is the line (LN) connecting the first point (P1) and the second point (P2) and whose width is the distance from the line to the center pointer (CP). The user may select the third point (P3) by adjusting the direction of the camera (31) to position the center pointer (CP) at the third vertex of the surface that projects the bottom (BS) of the aerial scaffolding onto the ground (5). When the third point (P3) is selected, the processor (10) can calculate the shortest distance from the line (LN) connecting the first point (P1) to the second point (P2) to the third point (P3) and determine this as the width. The measured length and width can be displayed in the input space (D6).

[0251] FIG. 44 is a drawing showing a state in which a cube (CB), an augmented reality object created to measure an aerial ladder according to one embodiment, is moved in the air.

[0252] The cube (CB) display step (S42c) may be performed after the third point (P3) is selected. The cube (CB) may have a length determined in the length measurement step (S42a), a width determined in the width measurement step (S42b), and a height of a predetermined unit length as an augmented reality object. The processor (10) may generate the cube (CB) and display it on the display (41). In this state, the displayed cube (CB) is generated with the approximate length, width, and predetermined height measured by the user, and therefore may not completely match the actual aerial scaffold. Therefore, it is necessary to move the cube (CB) toward the aerial scaffold so that the cube (CB) overlaps with the aerial scaffold and adjust the size of the cube (CB).

[0253] The position adjustment step (S42d) is a step of moving the cube (CB) formed on the ground (5) in a direction away from the ground (5) and moving it toward the aerial scaffolding. In the position adjustment step (S42d), the work interface may include a position adjustment button (B38) for moving the position of the cube (CB) in the length, width, and height directions, a distance selection button (B39) for selecting a distance to be moved by selecting the position adjustment button (B38), and a rotation slide bar (B40) for rotating the cube (CB). The distance selection button (B39) may include a 0.1 m button, a 1 m button, a 10 m button, etc.

[0254] When the user selects the height increase button (B38a) from the position adjustment button (B38), the processor (10) can move the cube (CB) upwards by the number of times the button has been selected and display it on the display (41). The user can select any one of the height increase button (B38a), the height decrease button (B38b), the first width movement button (B38c), the second width movement button (B38d), the first length movement button (B38e), and the second length movement button (B38f) while selecting the distance selection button (B39) to overlap the cube (CB) with the field scaffold (4b). An arrow object (K3) indicating the same direction as the position adjustment button (B38) can be displayed overlapping the cube (CB). The arrow object (K3) can be moved or rotated together with the cube (CB) depending on the position and direction. The user can check the cube (CB) that has reached a position overlapping with the aerial scaffold and the aerial scaffold of the field image.

[0255] The user can rotate the cube (CB) around an axis perpendicular to the ground by moving the rotation slide bar (B40) left or right. The user can adjust the rotation of the cube (CB) so that the cube (CB) overlaps the aerial scaffolding exactly.

[0256] The size adjustment step (S42e) can be performed in parallel with and independently of the position adjustment step (S42d). The size adjustment step (S42e) is a step for adjusting the size of the cube (CB) similarly to the method described with reference to FIG. 13. In the size adjustment step (S42e), the user can select the face button (B16) while selecting the size increase button (B14) or the size decrease button (B15). The processor (10) can adjust the size of the cube (CB) by increasing or decreasing the size of the selected face according to the user's input and display the adjusted size on the display (41). The user can adjust the size of the cube (CB) so that the cube (CB) overlaps the aerial scaffolding.

[0257] FIG. 45 is a drawing showing a state in which a cube (CB), an augmented reality object created to measure an aerial scaffold according to one embodiment, is adjusted in size and position to match the aerial scaffold.

[0258] As illustrated in Fig. 45, the user can align the cube (CB) displayed on the display (41) with the aerial scaffolding shown in the field image. The user can select the confirmation button (B37) while aligning the cube (CB) displayed on the display (41) with the aerial scaffolding to complete the input of the aerial scaffolding structure. When the user selects the confirmation button (B37), the processor (10) can confirm the structure of the aerial scaffolding input by the user and take a picture of the aerial scaffolding. Once the structure of the aerial scaffolding is confirmed, the scaffolding quantity can be calculated, and the result of the quantity calculation can be reflected in the work details and displayed.

[0259] Fig. 46 is a drawing showing a state in which an obstacle (WA) exists between the camera (31) and the scaffold installation location in a virtual scaffold installation mode according to one embodiment.

[0260] In the virtual scaffolding installation mode, the scaffolding input step (S30) must be performed while capturing the location (A3) where the scaffolding is to be installed with a camera (31). However, an obstacle (WA) may exist between the camera (31) and the location (A3) where the scaffolding is to be installed. The obstacle (WA) may include various structures existing at the site (3). The site (3) may include various temporary or non-temporary structures such as large storage tanks, multiple pipes, temporary buildings, and tents. These obstacles (WA) may block the view toward the location (A3) where the scaffolding is to be installed. In this case, in the virtual scaffolding installation mode, it may be difficult to accurately determine the size and location of the virtual scaffold (4b) because the display (41) is obscured by the obstacle (WA).

[0261] If the camera (31) is in an environment where it is difficult to capture the location (A3) where the scaffold is to be installed, it may be difficult to apply augmented reality. In such a case, a method for verifying the quantity of scaffolding using augmented reality according to one embodiment can utilize a method of installing a virtual scaffold (4a) in a different location without obstacles (WA) and then moving the location of the virtual scaffold (4a).

[0262] Fig. 47 is a drawing illustrating a step of creating and moving a virtual scaffold (4a) in a location (A4) where no obstacle (WA) exists in a virtual scaffold installation mode according to one embodiment.

[0263] In order to install a virtual scaffold (4a) in a space with a blocked view, the user can move (G1) to a space (A4) with an unblocked view and create a virtual scaffold (4a). The step of creating a virtual scaffold (4a) in a space (A4) with an unblocked view has been described with reference to FIG. 8. The created virtual scaffold (4b) can be displayed on the display (41b). After creating a virtual scaffold (4a) in a space (A4) with an unblocked view, the virtual scaffold (4a) can be moved (G2) to a space (A3) with an unblocked view. The step of moving (G2) the virtual scaffold (4a) can use the method described with reference to FIG. 15. After moving the virtual scaffold (4a) to a space with a blocked view (A3), when the user moves to the space with a blocked view (A3) and checks the display (41), the virtual scaffold (4a) can be checked on the display (41c).

[0264] Fig. 48 is a drawing explaining a method of measuring a complex-shaped field scaffold (4b) by dividing it in a field scaffold measurement mode according to one embodiment.

[0265] Depending on the intended use of the scaffold, its structure can be complex. Scaffolds can be installed in complex structures, including tall scaffolds, low scaffolds, aerial scaffolds, and scaffolds with different base shapes. In these cases, measuring the entire scaffold at once can be difficult.

[0266] A method for verifying scaffolding quantity using augmented reality according to one embodiment can divide a single continuous scaffold into multiple scaffolds and measure them. Similar to the description with reference to FIGS. 19 and 20, multiple field scaffolds (4b) can be measured within a single work number, and the work records for measuring multiple field scaffolds (4b) can be combined.

[0267] For example, if a single scaffold has multiple sections with different heights, the field scaffold (4b) illustrated in Fig. 48 can be divided into multiple sections (E1 to E4) and measured. The field scaffold measurement details divided into four sections (E1 to E4) can be added together and treated as the quantity of a single scaffold.

[0268] The present disclosure has been described in detail through specific examples. The above description is merely an example of applying the principles of the present disclosure, and other configurations may be included without departing from the scope of the present invention.
