Description

  The present invention relates to a structure inspection support system that supports inspection of deformation of a concrete structure.

  Over time, the surface of the concrete structure will be deformed, such as cracks. If left untreated, there is a risk that the concrete will peel off and cause damage to third parties. There is a risk of deteriorating the strength and function of the structure.

  For this reason, in concrete structures, inspections and inspections for surface deformation are conducted immediately after completion, and inspection inspections are repeated periodically thereafter, and changes from the initial stage of occurrence such as the distribution range, size, and width of deformations are repeated. It is required to record and grasp over time and to analyze and diagnose the strength and functional soundness of structures.

For example, Patent Literature 1 (Japanese Patent Laid-Open No. 2005-207044) discloses a tunnel health diagnostic system that collectively judges the health against peeling and the mechanical health due to external force.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is a structure inspection support system 1 that supports inspection of deformation of a concrete structure. Here, the deformation of concrete structures is cracking, peeling, peeling, floating, leaking water, rust, bean plate, slip, rebar exposure,
This refers to free lime and other damages and deterioration. Hereinafter, a case where the structure inspection support system 1 checks “cracks” will be described as an example. However, the structure inspection support system 1 can cope with the listed enumerations as described above.

FIG. 1 is a diagram showing a system configuration of a structure inspection support system 1 according to an embodiment of the present invention. As the server 10, a general-purpose server having functions such as a data processing function, a data storage function, and a data transmission / reception function can be used, and an office where an inspection engineer having a skill capable of inspecting the deformation of a concrete structure works. It is assumed that it will be installed in

  The tablet-type terminal 30 can use a general-purpose information processing terminal having functions such as a data processing function, a photographing function, and a communication function. In the present embodiment, for example, a tablet-type terminal 30 such as iPad (registered trademark) is used as such an information processing terminal, but an information processing terminal such as a notebook computer or a spurphone may be used. Such a tablet-type terminal 30 is assumed to be carried by an operator who photographs the deformation of a concrete structure.

  Further, the tablet terminal 30 and the server 10 can perform data communication with each other via the network relay device 20 and the communication network 5 such as the Internet.

  Next, a method of using the structure inspection support system 1 according to the embodiment of the present invention will be described. FIG. 2 is a diagram illustrating a state where an operator takes a picture of a cracked portion of a concrete structure (tunnel T) with the tablet-type terminal 30.

  When photographing the cracked portion with the tablet terminal 30, the unique code 50 is always photographed together. The unique code 50 has unique unique information and a predetermined length D. FIG. 3 is a diagram illustrating an example of the unique code 50. As shown in FIG. 3, the unique code 50 having a substantially square shape is always used with one side having a predetermined length D.

  In the structure inspection support system 1 according to the present invention, the image of the size of the cracked portion and the like is analyzed by imprinting the unique code 50 having a predetermined length D in the photographing data. In addition, the unique data of the unique code 50 is always associated with one cracked portion so as to acquire the photographing data, so that the photographing data can be managed over time.

  In the present embodiment, a QR code (registered trademark) is used as the unique code 50, but a barcode or the like may be used. In short, any unique code 50 may be used as long as it has unique identification information that can be photographed.

  The unique code 50 may be arranged on the concrete structure every time the photographing data is acquired, but may be always attached in the vicinity of the cracked portion. In that case, it is preferable to provide a surface coating having high weather resistance on the surface of the unique cord 50.

  Next, an operation process of the tablet terminal 30 when the cracked part is photographed by the tablet terminal 30 will be described. FIG. 4 is a flowchart of the photographing data acquisition process performed by the tablet terminal 30.

  In FIG. 4, when the photographing data acquisition process is started in step S100, an assist screen shown in FIG. 5 is displayed on the touch function compatible display 32 of the tablet terminal 30 in the subsequent step S101.

A touch function compatible display 32 is provided on one main surface of the tablet terminal 30, and a photographing unit 33 is provided on the other main surface. In the shooting mode of the tablet terminal 30, the video acquired by the shooting unit 33 is displayed on the touch function display 32 in real time. Further, on the touch function compatible display 32, after the angle of the image acquired by the photographing unit 33 is determined, a shutter icon 40 for displaying the photographing data by the photographing unit 33 when the user presses or touches is displayed. Has been. As a function of such a tablet-type terminal 30, any known technique can be used.

  Further, the display 32 corresponding to the touch function displays two displays, a first frame display 41 and a second frame display 42. In the first frame display 41, it is assumed that the angle of the tablet terminal 30 is adjusted so that the unique code 50 to be photographed together with the cracked portion is accommodated. Further, it is assumed that the angle of the tablet terminal 30 is adjusted so that the entire cracked part is accommodated in the second frame display 42.

  In the assist screen display shown in FIG. 5, for the first frame display 41, a message such as “Please enter the unique code within the frame” is notified to the user by the first balloon display 43. ing. In addition, for the second frame display 42, a message such as “Please make the shooting target part fall within this frame” is notified to the user by the second balloon display 44.

  In step S102, it is determined whether or not a predetermined time has elapsed. If the determination in this step is YES, the process proceeds to step S103, and the balloon display such as the first balloon display 43 and the second balloon display 44 is erased, and actual shooting is performed. On the other hand, while the predetermined time has not elapsed and the determination in step S102 is NO, the process returns to step S101, and the assist screen display is continued.

  When the assist display as described above is finished, the user sets an angle so that a crack is included in the second frame display 42 while the unique code 50 is stored in the first frame display 41 in order to acquire shooting data. It is assumed that it is determined and the shutter icon 40 is touched. FIG. 6 is a diagram showing a screen display when shooting data is acquired by the tablet terminal 30.

  Returning to the flowchart, in step S104, it is determined whether or not the shutter icon has been touched. If the determination in this step is yes, the process proceeds to step S105, and acquisition of shooting data is executed.

  Subsequently, in step S106, it is determined whether or not the unique code 50 can be analyzed (readable). If the determination in step S106 is NO, the photographing data is not appropriate, so the process proceeds to step S108, and a message prompting re-shooting is displayed. In step 109, it is determined whether or not a predetermined time has elapsed. If this determination is YES, the process proceeds to step S110, the message prompting re-shooting is deleted, and the process returns to step S104 to prepare for re-shooting.

  On the other hand, if the determination in step S106 is YES, it is determined that appropriate shooting data has been acquired, and the process proceeds to step S107, where the unique code 50, shooting date / time data, and shooting data are transmitted to the server 10, and subsequent step S111. End the process.

  In the present embodiment, the unique code 50, the shooting date / time data, and the shooting data are transmitted from the tablet terminal 30 to the server 10 by communication. However, these data are stored in the memory from the tablet terminal 30. A configuration may be adopted in which data is stored in a card (not shown) or the like, and data stored in the memory card is input to the server 10.

  Next, an algorithm for processing each data transmitted from the tablet terminal 30 on the server 10 side as described above will be described. FIG. 7 is a flowchart of received data analysis / storage processing by the server 10.

  In FIG. 7, the reception data analysis / storage process flowchart is started when the server 10 receives the unique code 50, imaging date / time data, and imaging data from the tablet terminal 30 (step S <b> 201).

  Now, the structure inspection support system 1 according to the present invention automatically analyzes the imaging data received from the tablet-type terminal 30 or whether the inspection engineer having a deformed inspection skill analyzes manually. It is configured to be selectable.

  In step S202, it is determined whether or not a mode for automatically analyzing shooting data has been selected. If the determination in step S202 is YES, in step S203, analysis image data relating to the cracked portion is automatically generated based on the imaging data. As a technique for obtaining such analysis image data, a known image analysis technique can be used.

  Note that the analysis image data refers to data obtained by extracting the shape and size of the crack portion in the photographic data from the background.

  If manual image analysis is selected and the determination in step S202 is NO, the process proceeds to step S206, and the image data displayed on the display of the server 10 is traced with a pointing device or the like to create analysis image data. A message for prompting is displayed on the display or the like. Thereby, it is assumed that the inspection engineer inputs the analysis image data. In step S207, it is determined whether or not such input work has been completed. If completed, the process proceeds to step S204.

  In step S204, the crack length and crack width are calculated based on the analysis image data. At this time, the crack length and the crack width related to the size of the crack portion are calculated from the predetermined length D of the unique code 50 in the photographing data. Data such as crack length and crack width is defined as deformation scale data.

  In step S205, the imaging date / time data, imaging data, analysis image data, and deformation scale data are stored in a storage element (not shown) of the server 10 in accordance with the unique code. FIG. 8 is a diagram schematically showing the structure of data stored by the server 10.

  As shown in FIG. 8, the history of imaging date / time data, imaging data, analysis image data, and deformation scale data is accumulated corresponding to the unique code 50. Note that the association between the unique code 50 and the location data of the cracked portion is appropriately performed.

  In step S208, the received data analysis / storage process ends.

  As described above, each data corresponding to the unique code 50 stored on the server 10 side can be transmitted from the server 10 side to the tablet terminal 30 side in response to a request from the tablet terminal 30 side. Configure. FIG. 9 is a diagram illustrating a screen display example of the tablet terminal 30 when each data corresponding to the unique code 50 is transmitted to the tablet terminal 30 side. With such a display, the operator can grasp the progress of the inspection object at the time of acquiring the shooting data, and can acquire more appropriate shooting data.

As described above, in the structure inspection support system 1 according to the present invention, the server 10 captures the shooting date / time data, the shooting data, the analysis image data, and the deformation scale data corresponding to the unique code 50 in the received shooting data. The storing step is executed, and according to the structure inspection support system 1 according to the present invention as described above, the photographer having the deformation need not be the inspection engineer, and the evaluation by the inspection engineer from a remote location. This makes it possible to carry out simple maintenance work without the need for an inspection engineer to go to the site, thereby improving the efficiency of the inspection. In addition, the shortage of inspection engineers can be compensated.

  Further, since a history in which shooting date / time data, shooting data, analysis image data, and deformation scale data are stored corresponding to the unique code 50 is left, centralized management can be performed for a long time and continuously. And maintenance work can be performed efficiently.
