Description

[Technical Field]

[0001] The present invention relates to an information processing device, a display method, and an information processing program. [Background technology]

[0002] Traditionally, bridge as-built measurements have been carried out individually for items such as bridge length, girder warpage, and deflection.The general method is to display the measured values ​​in a comparison table or a two-dimensional graph showing the difference between the measured values ​​and the design values.

[0003] Patent Document 1 discloses that a display data generation unit calculates the difference between the design value and the actual measurement value based on the data acquired by the data acquisition unit, and then generates as-built display data for displaying the difference as a contour diagram (contour map) at a position corresponding to the surface of the three-dimensional structure using the coordinate value data.

[0004] Patent Document 2 discloses that a receiving unit receives actual measurement-related information including actual measurement values, coordinate information of the locations where the actual measurement values ​​are measured, and vector information indicating the extension direction of the actual measurement 3D model. Then, a display processing unit uses the coordinate information and the vector information to display a actual measurement 3D model based on the actual measurement-related information within the space of a target 3D model.

[0006] Patent Document 1 uses coordinate value data to display differences as a contour map (contour line map) at positions corresponding to the surface of a three-dimensional structure. Therefore, while it is possible to display the amount of warpage of a bridge, which is information on the z-axis direction of the three-dimensional structure, it is not possible to display information on the x-axis and y-axis directions of the three-dimensional structure.

[0007] In addition, in Patent Document 2, a display processing unit uses coordinate information and vector information to display a measured value 3D model based on measured value-related information within the space of a target 3D model. However, even if this technology is used, there is a possibility that it will not be possible to accurately grasp the finished state or quickly find defective parts.

[0008] One aspect of the present disclosure has been made in consideration of the above-mentioned conventional problems, and aims to provide a technology that makes it possible to grasp the completed state of a bridge or quickly find defective areas. [Means for solving the problem]

[0014] <Configuration example of information processing device> 1 is a diagram showing an example of the configuration of an information processing system 100 according to one embodiment of the present invention. The information processing system 100 includes an information processing device 1 and a display device 2. The information processing device 1 includes a storage unit 11, an acquisition unit 12, a first extraction unit 13, a second extraction unit 14, a difference calculation unit 15, a rank determination unit 16, and a display control unit 17.

[0015] The storage unit 11 stores in advance planned value data, which is three-dimensional coordinate data of the bridge at the design stage, and actual measurement value data, which is three-dimensional coordinate data of the bridge measured during or during construction.

[0016] The planned value data is expressed as grid data that divides the bridge at regular intervals. The grid data includes, for example, three-dimensional coordinate data for the center point of the grid, and type information that indicates the type of support, lattice point, girder end, etc. By referencing this type information, it is possible to determine which part of the bridge the grid data constitutes.

[0017] The actual measurement value data is converted into grid data so as to correspond to the planned value data and stored in the storage unit 11. The grid data generated from the actual measurement value data includes, like the planned value data, three-dimensional coordinate data of the grid center point and type information indicating the type of support, lattice point, girder end, etc.

[0018] Here, a description will be given of information acquired by the information processing device 1 according to one embodiment of the present invention. The information processing device 1 acquires information relating to the span length of the girder, the alignment of the girder, and the warpage of the girder from each of the planned value data and the actual measurement value data.

[0019] Figure 2 shows an example of a bridge framework structure and is a diagram for explaining the span length of a girder. As shown in Figure 2, for the leftmost girder, the span length is the distance between support Cs and support C2, and the distance between support C2 and support Cg. A support, also known as a bearing, is the connection between the superstructure and substructure of a bridge and has the function of transmitting the weight of the superstructure to the substructure. As shown in Figure 2, the span length can be expressed as a straight line along the X-axis.

[0020] Figure 3 shows an example of a bridge framework structure and is a diagram used to explain girder alignment. Girder alignment is the distance a panel point is separated from the reference line connecting the bridge's reference supports. As shown in Figure 3, for the leftmost girder, the reference supports are Cs and Cg, and the straight line connecting reference supports Cs and Cg is the reference line. The value indicating the distance each panel point (Cs, C1, C2, C3, Cg) is separated from this reference line in the Y-axis direction is called the girder alignment. A panel point is a point where members in a bridge framework structure intersect, and is also called a tangent point.

[0021] Figure 4 shows an example of a bridge frame structure and is a diagram for explaining girder warpage. Girder warpage is a value that indicates how much the girder is displaced in the height direction (Z-axis direction). As shown in Figure 4, for the leftmost girder, the girder warpage is shown based on each of the lattice points Cs to Cg, but it is also possible to calculate the girder warpage for each upper flange.

[0022] The acquisition unit 12 acquires planned value data, which is coordinate data of the bridge at the design stage, and actual measurement value data, which is coordinate data of the bridge measured during or at the time of construction, stored in the storage unit 11. As described above, the planned value data is expressed as grid data. Furthermore, the actual measurement value data is converted into grid data so as to correspond to the planned value data.

[0023] The first extraction unit 13 extracts, as first extracted data, at least one of the planned value of the girder, which is the distance of the lattice points from the reference line connecting the reference supports of the bridge, and the planned value of the span length, which is the distance between the supports, from the planned value data acquired by the acquisition unit 12. In the following explanation, the first extraction unit 13 will be described as extracting the planned value of the girder, the planned value of the span length, and the planned value of the girder warp from the planned value data.

[0024] When extracting a planned value according to the girder, the first extraction unit 13 extracts points whose type information indicates a fulcrum from the grid data of the planned value data. Then, the first extraction unit 13 extracts points that belong to the same framework line based on the grid data of the fulcrum. A framework line is the center line of the framework between the fulcrums.

[0025] The first extraction unit 13 references the type information of the grid data belonging to the same framework line and extracts grid data of the grid points. Then, the first extraction unit 13 calculates the planned value of the girder, which is the distance of the grid points from the reference line connecting the reference supports of the bridge.

[0026] Furthermore, when extracting the planned value of the span length, the first extraction unit 13 extracts points whose type information indicates a fulcrum from the grid data of the planned value data. Then, the first extraction unit 13 calculates the span length based on the grid data of the fulcrums adjacent in the X-axis direction.

[0027] Furthermore, when extracting the planned value of the girder warpage, the first extraction unit 13 extracts points whose type information indicates a fulcrum from the grid data of the planned value data. Then, the first extraction unit 13 extracts points belonging to the same framework line based on the grid data of the fulcrum, and calculates the girder warpage, which is the displacement of each point in the Z-axis direction.

[0028] The second extraction unit 14 extracts, as second extraction data, actual measurement values ​​corresponding to the first extraction data from the actual measurement values ​​of the girders and the span lengths from the actual measurement value data acquired by the acquisition unit 12. Note that in the following explanation, a case will be described in which the second extraction unit 14 extracts actual measurement values ​​of the girders, the span lengths, and the warpage of the girders from the actual measurement value data.

[0029] The second extraction unit 14 extracts the actual measured values ​​of the girder, the actual measured values ​​of the span length, and the actual measured values ​​of the girder warp based on the grid data of the supports extracted from the grid data of the actual measured value data in a manner similar to that of the first extraction unit 13.

[0030] The difference calculation unit 15 calculates the difference between the first extracted data and the second extracted data as a first difference value. The difference calculation unit 15 also calculates the difference between the planned value of girder warp and the actual measured value of girder warp as a second difference value. In the following description, the difference calculation unit 15 calculates the difference value of girder direction, the difference value of span length, and the difference value of girder warp from the planned values ​​of girder direction, the planned values ​​of span length, and the planned values ​​of girder warp extracted by the first extraction unit 13, and the actual measured values ​​of girder direction, the actual measured values ​​of span length, and the actual measured values ​​of girder warp extracted by the second extraction unit 14.

[0031] 5 is a diagram for explaining a method for calculating the difference value of a digit sequence. The difference calculation unit 15 calculates a vector a0 that points from the reference support point Cs, which is the start point of the sequence, to the reference support point Cg, which is the end point, and then normalizes the vector a0 to calculate the vector a. The magnitude of this vector a is set to "1."

[0032] Next, the difference calculation unit 15 calculates a vector b that points from the planned value Ca of the measurement point to the actual measured value Ca'. Then, the difference calculation unit 15 calculates the cross product of vector a and vector b. The magnitude of this cross product is the area of ​​a parallelogram formed by vector a and vector b. Because the magnitude of vector a is "1", the area of ​​the parallelogram is the magnitude of the perpendicular component of vector b relative to vector a. The magnitude of this perpendicular component of vector b is the difference value in digits.

[0033] The difference calculation unit 15 also calculates the difference in span length by subtracting the actual measured value of the span length from the planned value of the span length.The difference calculation unit 15 also calculates the difference in girder warp by subtracting the actual measured value of the girder warp from the planned value of the girder warp.

[0034] The rank determining unit 16 determines which of a plurality of ranks indicating ranges of predetermined difference values ​​the difference value of the span length and the curvature of the girder calculated by the difference calculating unit 15 belongs to.

[0035] Figure 6 is a diagram for explaining the ranks of girder warp, alignment, and span length. The rank determination unit 16 determines the rank by comparing the difference value of girder warp with a separately calculated allowable value (absolute value). For example, if the span length is L (m), the rank determination unit 16 calculates the allowable value of girder warp as 25 + L / 2 (unit: mm).

[0036] If the difference in the warp of a digit is equal to or greater than the +tolerance value, the rank determining unit 16 assigns a rank of "1" to the warp of that digit. If the difference in the warp of a digit is within the range of +tolerance value to +10 mm, the rank determining unit 16 assigns a rank of "2" to the warp of that digit. If the difference in the warp of a digit is within the range of +10 mm to 0 mm, the rank determining unit 16 assigns a rank of "3" to the warp of that digit. If the difference in the warp of a digit is within the range of 0 mm to -10 mm, the rank determining unit 16 assigns a rank of "4" to the warp of that digit. If the difference in the warp of a digit is within the range of -10 mm to -tolerance value, the rank determining unit 16 assigns a rank of "5" to the warp of that digit. If the difference in the warp of a digit is equal to or less than the -tolerance value, the rank determining unit 16 assigns a rank of "6" to the warp of that digit.

[0037] The rank determination unit 16 also determines the color to display the digit warp depending on the rank of the digit warp. For example, the rank determination unit 16 sets red for rank "1", orange for rank "2", yellow for rank "3", green for rank "4", light blue for rank "5", and blue for rank "6".

[0038] If the rank determination unit 16 indicates that the difference value for the digit is shifted to the L side (left side) by more than a separately calculated tolerance, the rank determination unit 16 assigns the rank of that digit to "1." If the rank determination unit 16 indicates that the difference value for the digit is shifted to the L side by a range of 10 mm to 10 mm, the rank determination unit 16 assigns the rank of that digit to "2." If the rank determination unit 16 indicates that the difference value for the digit is shifted to the L side by a range of 10 mm to 0 mm, the rank determination unit 16 assigns the rank of that digit to "3." If the rank determination unit 16 indicates that the difference value for the digit is shifted to the R side (right side) by a range of 10 mm to 0 mm, the rank determination unit 16 assigns the rank of that digit to "4." If the rank determination unit 16 indicates that the difference value for the digit is shifted to the R side by a range of 10 mm to 10 mm, the rank determination unit 16 assigns the rank of that digit to "5." Furthermore, if the difference value for a digit indicates that it is shifted to the R side by more than the allowable value, the rank determination unit 16 assigns the rank for that digit to "6".

[0039] Furthermore, the rank determination unit 16 determines the color to be used to display the digit warp according to the rank of the digit sequence. For example, the color coding for the rank of the digit sequence is the same as the color coding for the rank of the digit warp described above.

[0040] As shown in FIG. 6, the rank determining unit 16 also determines the rank of the span length difference value, from "1" to "6", in the same way as for the girder warpage, and sets a color corresponding to the determined rank.

[0041] The display control unit 17 displays a three-dimensional model of the bridge based on the planned value data on the display device 2, and also displays the first difference value and the second difference value on the three-dimensional model in a distinguishable manner. In the following explanation, the display control unit 17 will be described as displaying the difference value of the girder, the difference value of the span length, and the difference value of the girder warp in a distinguishable manner.

[0042] Fig. 7 is a diagram showing an example of the display of span length difference values. For example, the display control unit 17 displays the span lengths in colors corresponding to ranks according to the span length difference values, as shown in the area P1 surrounded by a dashed line on the left side of Fig. 7. On the left side of Fig. 7, three span lengths are displayed, and the span lengths are displayed as cylinders. The span length difference values ​​are displayed as cylinders so that they can be distinguished from the difference values ​​of the beam lengths and the difference values ​​of the beam curvature, which will be described later.

[0043] Fig. 8 is a diagram showing an example of displaying the difference value of the girder order. For example, the display control unit 17 displays the difference value of the girder order in a color corresponding to the rank according to the difference value of the girder order, as shown in the area P2 surrounded by a dashed line on the left side of Fig. 8. As shown in Fig. 8, the difference value of the girder order is displayed as a sphere. The reason why the difference value of the girder order is displayed as a sphere is to make it possible to distinguish it from the difference value of the span length and the difference value of the girder camber, which will be described later.

[0044] Fig. 9 is a diagram showing an example of the display of the difference in girder warpage. For example, as shown in the area P3 surrounded by the dashed line in Fig. 9, the display control unit 17 displays the difference in girder warpage on the upper surface of the upper flange in a color corresponding to the rank according to the difference in girder warpage. As shown in Fig. 9, the difference in girder warpage is displayed as a surface in the display format. The reason for displaying the difference in girder warpage as a surface is to make it possible to distinguish it from the difference in span length and the difference in girder length.

[0045] The display control unit 17 may display on the display device 2 the difference value of span length shown in Figure 7, the difference value of the girders shown in Figure 8, and the difference value of the girders' camber shown in Figure 9, superimposed on the same screen, or may display each difference value on a separate screen.

[0046] <Processing Procedure of Information Processing Device 1> 10 is a flowchart for explaining the processing procedure of the information processing device 1 according to the embodiment of the present invention. First, the acquisition unit 12 acquires planned value data, which is coordinate data of the bridge at the design stage, and actual value data, which is coordinate data of the bridge measured during or at the time of construction, stored in the storage unit 11 (S11). For example, the acquisition unit 12 extracts planned value data and actual value data of points belonging to the same frame line based on the grid data of the supports.

[0047] Next, the first extraction unit 13 extracts at least one of the planned value of the girder and the planned value of the span length as first extracted data from the planned value data acquired by the acquisition unit 12 (S12). Note that the first extraction unit 13 may extract the planned value of the girder, the planned value of the span length, and the planned value of the girder warp from the planned value data.

[0048] Next, the second extraction unit 14 extracts, as second extraction data, the actual measurement values ​​of the girders and the span lengths that correspond to the first extraction data from the actual measurement data acquired by the acquisition unit 12 (S13). Note that the second extraction unit 14 may also extract the actual measurement values ​​of the girders, the span lengths, and the warpage of the girders from the actual measurement data.

[0049] Next, the difference calculation unit 15 calculates the difference between the first extracted data and the second extracted data as a first difference value. The difference calculation unit 15 also calculates the difference between the planned value of girder warp and the actual measured value of girder warp as a second difference value (S14). At this time, the rank determination unit 16 determines which of a plurality of ranks indicating a predetermined range of difference values ​​the difference values ​​of the girder alignment, span length, and girder warp calculated by the difference calculation unit 15 fall into. The rank determination unit 16 then stores the rank corresponding to the difference value of the girder alignment, the rank corresponding to the difference value of the span length, and the rank corresponding to the difference value of the girder warp in the storage unit 11 in association with the grid data.

[0050] Next, the acquisition unit 12 determines whether or not the processing of all the planned value data and actual measurement value data stored in the storage unit 11 has been completed (S15). If there is any planned value data and actual measurement value data for which processing has not been completed (S15, No), the process returns to step S11, where the acquisition unit 12 acquires the planned value data and actual measurement value data of points belonging to another skeleton line, and repeats the subsequent processing.

[0051] Also, when processing of all planned value data and actual value data has been completed (S15, Yes), the display control unit 17 displays a three-dimensional model of the bridge on the display device 2 based on the planned value data stored in the memory unit 11 (S16).

[0052] Then, the display control unit 17 displays the first difference value and the second difference value on the three-dimensional model in a distinguishable manner (S17). Specifically, the display control unit 17 references the rank associated with the grid data stored in the storage unit 11 and displays them on the three-dimensional model in a color corresponding to the rank. At this time, as described above, the display control unit 17 displays the difference value of the girder, the difference value of the span length, and the difference value of the girder warp on the three-dimensional model in different display forms.

[0053] <Advantages of the information processing device 1 according to this embodiment> As described above, according to the information processing device 1 of this embodiment, the display control unit 17 displays a 3D model of the bridge based on the planned value data on the display device 2, and displays the first difference value on the 3D model in an identifiable manner. This makes it possible to grasp the completed state of the bridge and quickly find defects.

[0054] Furthermore, the display control unit 17 displays the first difference value on the display device 2 in a color corresponding to the rank determined by the rank determination unit 16. This makes it easier to understand the completed state of the bridge and quickly find defective areas.

[0055] Furthermore, the display control unit 17 further displays the second difference value on the three-dimensional model in a distinguishable manner, which makes it easier to grasp the completed state of the bridge and quickly find defective parts.

[0056] Furthermore, the display control unit 17 displays the first difference value corresponding to the girder alignment, the first difference value corresponding to the span length, and the second difference value in different display formats, so that it is possible to display the difference value so that it is possible to distinguish between the girder alignment difference value, the span length difference value, and the girder camber difference value.

[0057] Furthermore, the difference calculation unit 15 calculates the cross product of the normalized first vector and second vector to calculate the difference value exactly to the digit, so that the difference value exactly to the digit can be easily calculated.

[0058] <Software implementation example> The functions of the information processing device 1 (hereinafter referred to as "device") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device.

[0059] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The functions described in each of the above embodiments are realized by executing the program using the control device and storage device.

[0060] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0061] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.
