In bar arrangement inspection using images, in order to accurately measure the diameter and average spacing of reinforcing bars, for example, the length of one side in the image is about several tens of centimeters to several meters in the inspection area of the wall or slab to be inspected. Images are often shot in such a shooting range as On the other hand, the inspection area of a wall or slab to be inspected in one bar arrangement inspection may have a side length of several meters to ten and several meters. For this reason, if the inspection area is larger than the imaging range that can be measured with the desired measurement accuracy, the inspection area is divided into multiple images, the multiple images are measured, and the measurement results are saved. ing.

However, when the inspection area is divided into multiple parts and photographed and measured, image photographing, measurement,
and a series of operations including storage of measurement results are repeated multiple times.

Therefore, when the photographed image and the measurement result for the image are displayed, the information displayed as the measurement result is information such as the size, number, and average spacing of the reinforcing bars in the measured image. Therefore, for example, when the photographed image and the inspection result are displayed, the inspection area is divided into a plurality of areas, photographed, and measured, and the number and average interval of reinforcing bars in the entire inspection area are grasped. difficult.

FIG. 2 is a perspective view for explaining an example of an image capturing method.

FIG. 2 shows an example of an image capturing method when inspecting the reinforcement arrangement of wall reinforcement using the reinforcement arrangement inspection system 1 of the present embodiment. In FIG. 2, the zx plane in the xyz orthogonal coordinates is the horizontal plane, and the y direction is the vertical direction. In the following description, vertically extending rebars 5
are called vertical bars 5, and horizontal reinforcing bars 6 are called horizontal bars 6.

When inspecting reinforcement arrangement using the reinforcement arrangement inspection system 1, for example, as shown in FIG.
A user (inspector) 10 of the bar arrangement inspection system 1 holds the bar arrangement inspection system 1 and captures an image of the wall reinforcement inspection area with the camera 2 . The camera 2 in the bar arrangement inspection system 1 can capture an image of a predetermined angle of view (shooting range) from a viewpoint P. Here, assuming that an area 7 of the executed wall muscles (a plurality of vertical muscles 5 and horizontal muscles 6) is the inspection area, for example, by increasing the distance Z0 from the viewpoint P to the wall muscles, the inspection area 7 can be put in one image. However, by lengthening the distance Z0, the measurement accuracy of the size (for example, diameter) of the reinforcing bars, the average interval, and the like decreases. Therefore, when capturing an image, the distance Z0 is such that the dimension of one side in the capturing range 8 of one image is several tens of centimeters to several meters in the rebar that has been constructed.
to shoot. In this case, the entire inspection area 7 is photographed in a plurality of times, and the size, number, average interval, etc. of the reinforcing bars are measured for each of the plurality of image data acquired by the divisional photographing. For example, in the example shown in FIG. 2, first image data including six reinforcing bars 5 from the left end of 11 vertical bars 5 extending in the vertical direction (y-direction) in the inspection area 7, and A second
, and the size, number, average interval, etc. of reinforcing bars are measured for each of the first image data and the second image data. At this time, in the bar arrangement inspection system 1 of this embodiment,
Character information (for example, "split shooting") indicating that measurement is being performed by split shooting during the period when processing related to measurement is performed for the second image data to be measured among the two image data.
character string) is displayed on the display unit 37 of the information processing device 3 . Further, in the bar arrangement inspection system 1, part of the measurement information for the image data measured second is integrated with the measurement information for the image data measured before (that is, the first) the image data. For example, when the second image data is measured after the measurement of the first image data, the bar arrangement inspection system 1 performs the processing related to the measurement of the second image data (image data acquisition , measurement, and display of the measurement information), a screen including a character string such as "split shooting" is displayed on the display unit 37. FIG. At this time, the bar arrangement inspection system 1 integrates part of the measurement information of the second image data (for example, the number of reinforcing bars and the average interval) with the measurement information of the first image data. Furthermore, in the bar arrangement inspection system 1 of the present embodiment, the integrated measurement information is displayed together with the measurement information of the second image data.

FIG. 3 is a flowchart illustrating an example of processing performed by the information processing device 3 according to one embodiment.

When the power of the camera 2 and the information processing device 3 is turned on to start the rebar measurement process, the information processing device 3 first acquires and displays image data as shown in FIG. 3 (step S1
). The processing of step S1 is performed by the control unit 31, the image acquisition unit 32, and the display unit 37. FIG. When the control unit 31 and the image acquisition unit 32 cooperate to display the image output from the camera 2 as a live view on the display unit 37, the user 10 touches a predetermined area (display unit 37), the control unit 31 causes the image acquisition unit 3
2 to acquire image data. The acquired image data is displayed on the display unit 37 . again,
When divisional photography is being performed, the control section 31 causes the display section 37 to display information indicating that divisional photography is being performed, such as "divided photography being performed", together with image data and the like.

Next, the information processing device 3 sets the measurement range in the acquired image data (step S
2) Predetermined measurements are performed for reinforcing bars within the set measurement range (step S3). The processing of steps S<b>2 and S<b>3 is performed by the measurement unit 33 under the control of the control unit 31 . step S2
and S3 may be the same as the processing in the known bar arrangement inspection system 1 (bar arrangement inspection device 3). For example, in step S2, the user can use the input unit 36 to specify the measurement range. Step S2 or S3 may include a process of normalizing the reinforcing bars in the acquired image data.

When the measurement (step S3) is finished, the information processing device 3 determines whether or not split shooting is being performed (step S4). The determination in step S4 is performed by the control unit 31 . If information indicating that split shooting is being performed is input from the input unit 36 when acquiring image data that is currently being measured, the control unit 31 determines that split shooting is being performed.

If divisional photography is being performed (step S4; YES), the information processing device 3 performs measurement information integration processing (step S5), and then displays the measurement information (step S6). On the other hand, if the split shooting is not being performed (step S4; NO), the information processing device 3 skips the processing of step S5 and displays the measurement information (step S6). Here, measurement information integration processing (step S
5) is a process of integrating a part of the measurement information obtained by the measurement of the image data currently being measured with the measurement information associated with the image data measured before the image data. . It should be noted that if divisional photography is being performed, the measurement information including the integrated measurement information is displayed in step S6.

Next, the information processing device 3 determines whether or not to perform split shooting (step S7). The determination in step S7 is performed by the control unit 31 . The control unit 31 determines which of an instruction to perform divisional imaging and another instruction (for example, an instruction to save the measurement information and terminate) has been input from the input unit 36 . When split shooting is to be performed (step S7; YES), the information processing device 3 changes the shooting direction (
division direction) is accepted (step S8). It should be noted that in step S8, instead of the imaging direction, an input of information indicating the position of the imaging range (reinforcing bars present in the image data) may be accepted. After that, the information processing device 3 saves the measurement information (step S9), step S1
return to the process of At this time, the information processing apparatus 3 causes the display unit 37 to display text information indicating that divisional photography is being performed, such as "divided photography is in progress". On the other hand, when split shooting is not performed (step S7;
NO), the information processing device 3 saves the measurement information (step S10), and ends the reinforcing bar measurement process. In steps S<b>9 and S<b>10 , the information processing device 3 causes the storage unit 38 to store the image data to be measured and the measurement information related to the image data in association with each other.

FIG. 4 is a flowchart illustrating an example of the measurement information integration process (step S5).
As described above, the measurement information integration process (step S5) is performed when the image data obtained by shooting during the divisional shooting is the object to be measured. When the measurement information integration process is started, the information processing device 3 acquires the measurement information associated with the previous image data (step S501
). The immediately previous image data is image data obtained by measuring the reinforcing bar immediately before obtaining the image data that is currently being measured. If the previous image data is the second or subsequent image data acquired by split imaging, the measurement information acquired in step S501 includes integrated measurement information.

Next, the information processing device 3 extracts information on the number of reinforcing bars included in the acquired measurement information, and for each type of reinforcing bar, the extracted number of reinforcing bars and the number of reinforcing bars measured from the image data currently being measured. The total number of reinforcing bars is calculated (step S502). After that, the information processing device 3
Retains the calculation formula for the number of reinforcing bars including the number of reinforcing bars for each image data as integrated measurement information (
step S503). Here, assuming that the number of vertical streaks 5 measured from the i-th acquired image data is Ni, the vertical streaks measured from each image data from the first measured image data to the I-th measured image data. The formula for calculating the total TN of the number of 5 is represented by the following formula (1).
TN=ΣNi=N1+...+NI (1)

Therefore, in step S503, the information processing device 3 holds, for example, information indicating the total number TN of the vertical stripes 5 and the calculation formula "N1+...+NI".

Next, the information processing device 3 extracts information on the average spacing of the reinforcing bars included in the acquired measurement information, and integrates the extracted average spacing with the average spacing measured from the image data currently being measured. Then, the average interval is calculated (step S504). After that, the information processing device 3 holds, as integrated measurement information, a formula for calculating an average interval including the average interval of reinforcing bars for each image (step S505). Here, the number of reinforcing bars measured from the i-th captured image is Ni, and the Ni
Assuming that the interval between the reinforcing bars located at both ends of the reinforcing bars of the book is Li, the calculation formula for the average interval Pi of the reinforcing bars in the i-th image is the following formula (2).
Pi=Li/(Ni-1)=Li/Xi (2)

Therefore, the average interval TP obtained by integrating the average interval measured from each image from the first captured image to the I-th captured image in divisional photography can be calculated, for example, by the following formula (3).
TP = (ΣLi)/(ΣXi)
=(L1+...+LI)/(X1+...+XI) (3)

Therefore, in step S505, the information processing device 3 holds, for example, information indicating the integrated average interval TP of the vertical stripes 5 and the calculation formula "(L1+...+LI)/(X1+...+XI)".

That is, in the bar arrangement inspection system 1 of the present embodiment, when displaying the measurement information for the image data acquired by capturing during the divisional capturing, the number of reinforcing bars and the average interval are expressed by formulas (1) and (3). indicate. As a result, the user 10 can easily understand from the measurement information that the measurement is being performed by split shooting. In addition, the user 10 can, for example, check the number of measured reinforcing bars and unmeasured reinforcing bars and check the average interval during measurement, thereby preventing measurement errors (inspection errors). can.

Specific examples of the inspection method and the display screen by the bar arrangement inspection system 1 according to the present embodiment will be described below with reference to FIGS. 5 to 9. FIG.

FIG. 5 shows an example of an inspection area 7 in a wall muscle and an imaging range 8 (8A to 8C) of one image. The inspection area 7 includes 20 vertical stripes 5 and 4 horizontal stripes 6 . For simplicity of explanation, the following description herein assumes that 20 longitudinal streaks 5 through the inspection area 7
are of the same type (main rebar) and have the same rebar number (for example, F1).
Here, the horizontal dimension in the shooting range 8 of one image set based on the measurement accuracy is, for example, longer than the arrangement interval of eight vertical stripes 5 and larger than the arrangement interval of nine vertical stripes 5. If it is short, it is necessary to take divided shots and measure them. In this case, for example, as shown in FIG. 5, the first image captures an imaging range 8 (8A) including eight vertical streaks 5 from the left end of the inspection area 7. FIG. Also, for example, the second image captures an imaging range 8B that includes the 9th vertical stripe 5 to the 16th vertical stripe 5 from the left end, and the third image includes the 4 vertical stripes 5 from the right end. The photographing range 8C is photographed. Note that the combination of the photographing ranges 8A to 8C of the three images shown in FIG. 5 is merely an example, and other combinations of the photographing ranges of the three images may be used. Also, the number of images to be dividedly photographed can be appropriately changed according to the inspection area 7 and the photographing range of one image.

FIG. 6 is a diagram showing an example of a display screen when the first image data is obtained.

When the power of the camera 2 and the information processing device 3 is turned on and the reinforcing bar measurement process is started, for example, a display screen 101 as shown in FIG. It is displayed in section 37 . The screen 101 includes an image display section 101a, a setting button 101b, a document confirmation button 101c, a shooting button 101d, and a measurement range setting button 1.

The image display section 101a is an area for displaying video data and image data output from the camera 2 . The setting button 101b is a button to be pressed when setting various types of information including information on the reinforcing bars in the inspection area 7 on the bar arrangement diagram. The form confirmation button 101c is a button to be pressed when displaying a form about the inspection result after measurement. The shooting button 101d is a button that is pressed when shooting an image. The measurement range setting button 101e is a button to be pressed when setting the measurement range. The measurement button 101f is a button to be pressed when starting measurement. The split shooting button 101g is a button that is pressed when split shooting is performed after the end of measurement. The save button 101h is a button to be pressed when saving the measurement information. The measurement information display unit 101i
This area displays the type of reinforcing bar to be measured, the design value (value on the bar arrangement diagram), and the actual measurement value (value measured from image data). Note that the types and layout of the buttons in FIG.
This is just one example. For example, the measurement range setting button 101e may be omitted, and the measurement range may be set first when the measurement button 101f is pressed.

The types and design values of reinforcing bars included in the measurement information display section 101i on the display screen 101 of FIG. . The predetermined input operation is, for example, an operation of inputting information designating the contents of the construction work, information designating the reinforcement arrangement diagram, information designating the inspection area 7 on the reinforcement arrangement diagram, and the like. A main bar F1 on the display screen 101 of FIG.

The user 10 of the bar arrangement inspection system 1, for example, finds eight vertical bars 5 (
For example, after adjusting the orientation and position of the camera 2 so that the imaging range 8A) in FIG. (step S1). After that, the user sets the reinforcing bar measurement range in the first image data, and causes the information processing device 3 to execute the reinforcing bar measurement process.

FIG. 7 is a diagram showing an example of a display screen of measurement information for the first image data.

After acquiring the first image data, the user 10 presses the measurement range setting button 101e, and selects the area (measurement range) 12 used for measuring the reinforcing bars in the image displayed on the image display unit 101a.
(step S2). In the example shown in FIG. 7, the measurement range 12 is set so as to include all eight vertical stripes 5 displayed. After specifying the measurement range 12, press the measurement button 1
When 01f is pressed, the information processing device 3 extracts reinforcing bars (vertical bars 5 and horizontal bars 6) within the measurement range 12, and measures the size (for example, diameter), number, average interval, etc. for each type of reinforcing bars. (Step S
3).

After that, the information processing device 3 determines that the image data currently being processed is the first image data, so it determines that the divided shooting is not being performed (step S4; NO), and the measurement information integration processing ( Step S5) is skipped and measurement information is displayed (step S6). At this time, a display showing the extracted reinforcing bars is added to the image display portion 101a on the display screen.
For example, in the image display portion 101a in the display screen 102 shown in FIG. 7, the ends of the extracted reinforcing bars are marked with circles. In addition, the number of reinforcing bars, the average interval, and the like measured from the image data are displayed in the actual measurement value column of the measurement information display section 101i. Vertical bar 5 (
Since there are eight main rebars F1), "8" is displayed in the cell displaying the number of main rebars F1 in the measured value column of the measurement information display section 101i. Also, if the measurement result of the distance of the vertical bars 5 at both ends of the eight vertical bars 5 (main bars F1) within the measurement range 12 is L1, then the distance between the main bars F1 in the measured value column of the measurement information display section 101i is For example, "L1/7=
100” is displayed. Also, although omitted in the screen 102 of FIG. 7, the measurement information display unit 1
Other measurement information, such as information on the diameter of the vertical reinforcement 5 (main reinforcement F1) and information on the number, interval, and diameter of the horizontal reinforcement 6, is displayed in the column of actual measurement values of 01i.

When the user presses the split shooting button 101g after finishing the measurement of the first image data (step S7; YES), for example, a dialog box for selecting the split direction is displayed on the display screen 102. FIG. There are two division directions, for example, the right direction and the downward direction. Figure 5
In the example of , the user 10 selects the right direction as the direction of division in order to photograph the measurement area 7 in the horizontal direction. After that, the information processing device 3 acquires the second image data according to the input operation of the user 10, and performs the reinforcing bar measurement processing on the image data.

FIG. 8 is a diagram showing an example of a display screen of measurement information for the second image data.

When split shooting is selected to acquire the second image data and measurement is performed on the image data, as shown in FIG.
01j is displayed. The display screen 103 also displays, for example, a thumbnail 101k of image data that has been measured. As a result, the user can easily understand that split photography is being performed. When displaying the thumbnail 101k, for example, not only the thumbnail of the image data immediately before the image data currently being processed, but also the thumbnails of a plurality of image data may be displayed.

When the measurement range 12 is set in the image (second image data) displayed on the image display section 101a of the display screen 103 and the measurement button 101f is pressed, the information processing device 3 measures the reinforcing bar within the measurement range 12. Extract and measure the size (e.g. diameter), number, average spacing, etc. for each type of rebar (
step S3). There are eight vertical bars 5 (main bars F1) within the measurement range 12 on the display screen 103 of FIG. 8, and all eight bars have been extracted. The number of F1) is "8". In addition, the eight vertical stripes 5 within the measurement range 12 (
Assuming that the measurement result of the distance between the vertical bars 5 at both ends of the main bar F1) is L2, the average interval between the vertical bars 5 (main bars F1) in the measurement information for the second image data is "L2/7".

After that, the information processing device 3 determines that the divided shooting is being performed (step S4; YES) because the image data currently being processed is the second image data, and the measurement information integration processing ( Step S5) is performed.

In the measurement information integration process, the information processing device 3 extracts information on the number of reinforcing bars included in the measurement information for the first image data, and calculates the total number of reinforcing bars (step S502).
At this time, for example, since the direction of divisional photography is the right direction (horizontal direction), the information processing device 3 selects the type of reinforcing bars for which the total number is calculated as a plurality of horizontally aligned reinforcing bars, i.e., vertical bars. 5 (main bar F1).

As described above, the number of vertical bars 5 (main bars F1) measured from the first image data is "8".
is. Therefore, the information processing apparatus 3 holds, as integrated measurement information related to the number of vertical stripes 5, the total number of vertical stripes 5 "16" and information indicating the total number calculation formula "8+8" (step S503). . The information indicating the calculation formula may be information including a calculation symbol such as "8+8", or may be information such as "8, 8" in which the number of reinforcing bars 5 detected from each image data is indicated by a delimiter such as a comma. Information in CSV (Character Separated Values) format separated by .

Further, the information processing device 3 extracts, for example, the information of the average spacing of the reinforcing bars included in the measurement information for the first image data, and calculates the integrated value of the average spacing of the reinforcing bars (step S50
4). The average interval of the vertical bars 5 (main bars F1) measured from the first image data is "L1/7=
100”. Therefore, the information processing device 3 uses the average interval TP (={L1+L2}/{7+7}) calculated by the above formula (3) as the integrated measurement information regarding the average interval of the vertical streaks 5.
) and information indicating the calculation formula “{L1+L2}/{7+7}” (step S50
5).

After creating and storing the integrated measurement information about the number of vertical bars 5 (main bars F1) and the average interval, the information processing device 3 ends the measurement information integration process and displays the measurement information (step S6).
. At this time, as shown in FIG. 8, the image display portion 101a on the display screen 103 is provided with a display indicating the extracted reinforcing bar (a circle at the end of the reinforcing bar). In addition, the number of reinforcing bars created by the measurement information integration process, the average interval, and the like are displayed in the actual measurement value column of the measurement information display section 101i.

As described above, in the measurement information integration process, the information processing device 3 creates the information indicating the total number “16” and the calculation formula “8+8” as the integrated measurement information regarding the number of vertical bars 5 (main bars 1). holding. Therefore, the main reinforcement F1 in the measured value column of the measurement information display section 101i
"8 + 8 = 16" is displayed in the cell displaying the number of . In addition, in the measurement information integration process, the information processing device 3 uses the integrated average interval TP (for example, TP=101) and the calculation formula “{L1+L2}/{ 7+7}” is created and held. Therefore, "{L1+L2}/{7+7}=101" is displayed in the cell displaying the average interval of the main reinforcements F1 in the measurement information display section 101i.
is displayed.

In this way, by displaying the number of reinforcing bars and the average interval in the measurement information for the second image in an integrated manner with the measurement information for the first image data, the user can understand that the divided shooting is being performed, Also, it is possible to easily grasp whether or not the measurement by the divided photographing can be ended. For example, a user viewing the display screen 103 in FIG. 8 can easily understand that measurement by split shooting must be continued because the measured value of the number of reinforcing bars is smaller than the set value. Moreover, the user who viewed the display screen 103 of FIG. 8 can determine the presence or absence of unsuccessfully extracted reinforcing bars based not only on the reinforcing bar extraction results displayed on the image display unit 101a, but also on the number of reinforcing bars and the measured average spacing of the reinforcing bars. etc. can be confirmed.

When the user presses the split shooting button 101g after the measurement of the second image data is completed (step S7; YES), a dialog box for selecting the split direction is displayed on the display screen 103, for example. When the user 10 selects the right direction as the division direction, the information processing device 3 acquires the third image data according to the input operation of the user 10, and performs the reinforcing bar measurement processing on the image data.

FIG. 9 is a diagram showing an example of a display screen of measurement information for the third image data.

When split shooting is selected to acquire the third image data and measurement is performed on the image data, as shown in FIG.
01j is displayed. The display screen 104 also displays, for example, thumbnails 101k and 101m of image data that has been measured. The upper thumbnail 101k is the thumbnail of the first image data, and the lower thumbnail 101m is the thumbnail of the second image data. As a result, the user can easily understand that split photography is being performed. Note that the thumbnail displayed on the display screen 104 may be only the thumbnail 101m of the image data immediately preceding the image data currently being processed.

When the measurement range 12 is set in the image (the third image data) displayed on the image display section 101a of the display screen 104 and the measurement button 101f is pressed, the information processing device 3 measures the reinforcing bar within the measurement range 12. Extract and measure the size (e.g. diameter), number, average spacing, etc. for each type of rebar (
step S3). There are four vertical bars 5 (main bars F1) within the measurement range 12 on the display screen 104 of FIG. 9, and all four bars have been extracted. The number of F1) is "4". In addition, the four vertical stripes 5 within the measurement range 12 (
Assuming that the measurement result of the distance between the vertical bars 5 at both ends of the main bar F1) is L3, the average interval between the vertical bars 5 (main bars F1) in the measurement information for the third image data is "L3/3".

After that, the information processing device 3 determines that the divided shooting is being performed (step S4; YES) because the image data currently being processed is the third image data, and the measurement information integration processing ( Step S5) is performed.

In the measurement information integration process, the information processing device 3 extracts information on the number of reinforcing bars included in the integrated measurement information associated with the second image data, and calculates the total number of reinforcing bars (step S502). At this time, for example, since the direction of divisional photography is the right direction (horizontal direction), the information processing device 3 selects the types of reinforcing bars for which the total number is calculated as a plurality of horizontally aligned reinforcing bars,
That is, the vertical bar 5 (main bar F1) is specified.

As described above, the information on the number of reinforcing bars in the integrated measurement information associated with the second image data includes the total number of "16" and the information indicating the calculation formula "8+8". For this reason, the information processing device 3 uses the total number of the vertical stripes 5 as "20" as the integrated measurement information regarding the number of the vertical stripes 5,
Information indicating the calculation formula of the total number of threads "8+8+4" is held (step S503).

Further, the information processing device 3 extracts, for example, the information of the average spacing of the reinforcing bars included in the integrated measurement information associated with the second image data, and calculates the integrated value of the average spacing of the reinforcing bars (step S504). ). The average interval of the vertical stripes 5 (main stripes F1) measured from the second image data is "{L1+L2}/{7+7}=100". Therefore, the information processing device 3
As the integrated measurement information related to the average interval of the average interval TP calculated by the above formula (3)
(= {L1 + L2 + L3} / {7 + 7 + 3}) and the calculation formula "{L1 + L2 + L3} / {7
+7+3}” is held (step S505).

After creating and storing the integrated measurement information about the number of vertical bars 5 (main bars F1) and the average interval, the information processing device 3 ends the measurement information integration process and displays the measurement information (step S6).
. At this time, as shown in FIG. 9, the image display portion 101a on the display screen 104 is added with a display indicating the extracted reinforcing bar (a circle at the end of the reinforcing bar). In addition, the number of reinforcing bars created by the measurement information integration process, the average interval, and the like are displayed in the actual measurement value column of the measurement information display section 101i.

That is, "8+8+4=20" is displayed in the cell displaying the number of the main reinforcing bars F1 in the measured value column of the measurement information display section 101i. In addition, in the column of the actual measurement value of the measurement information display section 101i, the cell displaying the average interval of the main reinforcement F1 has "{L1+L2+L3}/{7+7+3
}=100” is displayed.

In this manner, by integrating and displaying predetermined items (for example, the number of reinforcing bars) in the measurement information associated with each of the plurality of pieces of image data obtained by split shooting, the user can easily measure the vertical bars 5. It is possible to easily grasp that the number has reached the number of design values. Therefore, for example, the user viewing the display screen 104 in FIG. 9 can press the save button 101h to end the process after the measurement process for the third image data is completed. This prevents acquisition of image data unnecessary for inspecting the bar arrangement and performing unnecessary measurement when measuring the reinforcing bar by performing divisional photography.

In the above description, as shown in FIG. 5, the horizontally elongated inspection area 7 is divided in the left and right directions for measurement. However, the measurement is not limited to this. Measurement is also possible.
