Description

Technology Field

[0001] The present invention relates to a special facility report content sharing system, and more specifically, to a special facility report content sharing system that allows for the sharing of report content regarding special facilities such as tunnels, namely 3D image information, crack photo information, and report information regarding the facility, online while maintaining security. Background Technology

[0002] Tunnel construction can proceed in the order of tunnel excavation, reinforcement, and concrete lining installation. That is, reinforcing shotcrete is poured onto the rock face of the excavated tunnel to level the excavation surface, and then a non-woven fabric or waterproof sheet is attached to the outer surface of the shotcrete. After attaching the non-woven fabric or waterproof sheet to the outer surface of the shotcrete, concrete is poured on the inner side and cured to form the tunnel lining.

[0003] Cracks can occur in tunnel linings due to various causes. For example, cracks in the tunnel lining may occur due to repeated contraction and expansion caused by changes in ambient temperature. Cracks in the tunnel lining may include vertical cracks occurring on the lower part of the inner surface and longitudinal cracks occurring on the ceiling surface.

[0004] When performing a precise tunnel safety inspection to diagnose cracks in the tunnel lining, particularly in diagnosing longitudinal cracks in the ceiling surface, a method utilizing mobile trolleys, motor cars, or aerial work platforms may be used.

[0005] However, the mobile trolley method poses a risk of safety accidents during installation, such as ladder tipping, falls by investigators, and entrapment (collision) between trolleys. The motorcar method has the problem of high costs associated with motorcar contracts. The aerial work platform method suffers from work inefficiency due to administrative procedures. Furthermore, since all of these methods rely solely on visual inspection, they have limitations regarding the accuracy of the diagnosis.

[0006] In addition, to overcome these limitations, a method has been disclosed for preparing a report on tunnel safety diagnosis using mobile imaging and analysis means for precise tunnel safety diagnosis.

[0007] However, even in the case of such conventional tunnel safety inspections, there are limitations in that the report content obtained from the inspection results is printed and stored or shared in paper form, making it difficult to ensure the continuity of safety management for special facilities such as tunnels and posing a problem where safety management itself is difficult. The problem to be solved

Specific details for implementing the invention

[0019] Specific embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0020] The special facility report content sharing system (1) according to the present embodiment is configured to include a report content generation unit (100), a database unit (200), and a report content sharing unit (300), as shown in FIG. 1.

[0021] First, the above-mentioned report content generation unit (100) is a component that generates report content including a condition assessment and maintenance plan for special facilities, such as tunnels. That is, the above-mentioned report content generation unit (100) quickly and accurately secures image information of the inner wall of a tunnel based on tunnel specification information identified in advance for special facilities such as tunnels, automatically analyzes this information to diagnose the safety condition of the tunnel, such as cracks and deterioration, and generates it as report content.

[0022] To this end, the report content generation unit (100) according to the present embodiment is configured to include a tunnel specification identification means (110), a tunnel image information securing means (120), a data storage means (130), and a tunnel condition analysis means (140), as shown in FIG. 1.

[0023] First, the tunnel specification determination means (110) is a component that determines the overall specifications of the tunnel while moving continuously from one side of the tunnel to the other. In order to quickly and accurately secure image information of the inner surface of the tunnel by the tunnel image information securing means (120), the specifications, such as the height and width of all sections of the tunnel, must be accurately determined.

[0024] Although the height and width of the tunnel are roughly determined during construction, the height and width of each section are not accurately determined, so it is necessary to determine them accurately. Therefore, the means for determining tunnel specifications (110) accurately determines the internal specifications of the tunnel to be safety diagnosed in advance to secure tunnel specification information.

[0025] However, in order to determine the internal dimensions of the tunnel without obstructing traffic flow, such as blocking traffic in the tunnel, the report content generation unit (100) according to the present embodiment is configured with a vehicle mobile mapping system (MMS) that determines the dimensions while moving the tunnel dimensions determination means (110). The vehicle MMS is equipped with devices such as GPS, INS, odometer, and digital compass, which are sensors for determining the position and attitude of the vehicle, and sensors such as a CCD camera and SAR, which are sensors for collecting information related to the shape of terrain features for mapping.

[0026] In particular, it is desirable that the vehicle MMS according to the present embodiment is based on LiDAR and can obtain accurate tunnel specification information by scanning the height and width of each part of the tunnel while moving at high speed inside the tunnel without blocking traffic.

[0027] Next, the tunnel image information securing means (120) is a component that secures image information of the inner wall surface of the tunnel by scanning the inner surface of the tunnel while moving from one side to the other of the tunnel according to the tunnel size information identified by the tunnel size identification means (110). That is, the tunnel image information securing means (120) secures accurate tunnel image information by utilizing the tunnel size information obtained by the tunnel size identification means (110) and adjusting the camera in real time to an accurate focal length for individual sections and points while moving at a high speed like the tunnel size identification means (110).

[0028] To this end, in this embodiment, the tunnel image information securing means (120) is specifically composed of a moving means (122) and a camera (124) as shown in FIGS. 2 and 3. First, the moving means (122) is a component that moves at a constant speed while equipped with the camera (124), such as a car.

[0029] Next, the camera (124) is a component mounted on the vehicle (122) to photograph the inner surface of the tunnel. Of course, multiple cameras (124) may be installed, and in order to stably install and operate multiple cameras (124), the vehicle (122) may be further equipped with a camera installation part (126).

[0030] At this time, the camera installation unit (126) is installed at a predetermined angle so that the plurality of cameras (124) can photograph different ranges of the inner wall of the tunnel, as shown in FIGS. 2 and 3.

[0031] Meanwhile, in the tunnel safety diagnosis system (100) according to the present embodiment, the camera (124) preferably includes a visible image camera that captures a visible image and an infrared camera that captures an infrared thermal image. The image information captured by the visible image camera and the infrared camera, respectively, is used to diagnose different elements among the tunnel safety diagnosis elements.

[0032] Next, the data storage means (130) is a component that stores data such as tunnel specification information and tunnel image information obtained by the tunnel specification identification means (110) and the tunnel image information securing means (120). Accordingly, the data storage means (130) is installed in a separate space separated from the tunnel specification identification means (110) or the tunnel image information securing means (120), and may be installed together in a server room for stable retention and storage of data. Additionally, the data storage means (130) may be replaced by the database unit (200).

[0033] In this case, the data obtained by the tunnel specification identification means (110) and the tunnel image information securing means (120) may be transmitted in real time via a wired or wireless communication method, or provided in a state stored in a storage means after the data securing operation is completed.

[0034] Next, the tunnel condition analysis means (140) is a component that analyzes the deterioration state of the tunnel by analyzing the tunnel image information of the data storage means (130). That is, the tunnel condition analysis means (140) diagnoses the deterioration state that may occur in the tunnel by analyzing the tunnel image information stored in the data storage means (130) or directly transmitted by the tunnel image information securing means (120).

[0035] To this end, in this embodiment, the tunnel condition analysis means (140) is configured to include a crack extraction unit (141) and a deterioration extraction unit (142), as shown in FIG. 4. First, the crack extraction unit (141) is a component that automatically extracts crack occurrence sections from the tunnel image information. Specifically, as shown in FIG. 5, the crack extraction unit (141) automatically extracts cracks by varying the crack color tone of the visible image among the tunnel image information, and automatically measures the length and width information of the cracks.

[0036] In particular, in this embodiment, the crack extraction unit (141) has the advantage of being able to obtain an accurate crack width value regardless of changes in crack width according to each point by measuring the average value of the crack widths for 5 to 15 pixels as the crack width, rather than measuring the width of a single point when measuring the crack width.

[0037] In addition, the crack extraction unit (141) according to the present embodiment is preferably further equipped with a distortion correction unit (141a), a vertical / horizontal correction unit (141b), an image joining unit (141c), and an unfolded image creation unit (141d) to secure accurate tunnel image information, as shown in FIG. 6.

[0038] First, the distortion correction unit (141a) is a component that corrects image distortion caused by a lens in the tunnel image information. That is, as shown in FIG. 7, the distortion correction unit (141a) corrects distortion caused by a lens used in a camera and creates a correction file according to the camera used.

[0039] Next, the vertical / horizontal correction unit (141b) is a component that corrects an image taken on a slope among the tunnel image information into a frontal image. That is, as shown in FIG. 8, the vertical / horizontal correction unit (141b) specifies an arbitrary rectangle and inputs a length to transform it into a rectangle with the correct scale, thereby measuring the accurate length and area.

[0040] Next, the image joining unit (141c) is a component that joins multiple images captured separately from the tunnel image information. That is, as shown in FIG. 9, the image joining unit (141c) designates four common points in two images captured separately, and modifies and combines the two images while they are joined based on these points. By joining multiple images captured separately by the image joining unit (141c) in this way, there is an advantage of being able to process a large area.

[0041] Next, the above-mentioned unfolded image generation unit (141d) is a component that generates an unfolded image using an image corrected by a distortion correction unit (141a), a vertical / horizontal correction unit (141b), and an image joining unit (141c), as illustrated in FIG. 10. By generating an unfolded image using the above-mentioned unfolded image generation unit (141d), there is an advantage in being able to determine the accurate location and length of tunnel structures and cracks, etc.

[0042] Furthermore, it is preferable that the crack extraction unit (141) further comprises a drawing output unit (141e) that extracts cracks from the unfolded image created by the unfolded image creation unit (141d) and outputs the crack extraction result in a dxf file format. By outputting the crack automatic extraction result in a dxf file format by the drawing output unit (141e) in this way, there is an advantage of being directly compatible with CAD drawings.

[0043] In addition, in this embodiment, it is preferable for the crack extraction unit (141) to output crack information regarding crack length and crack width in a CSV file format. When the crack information identified by the crack extraction unit (141) is output in a CSV file format, it is easy to create a crack distribution map, which has the advantage of making it easy to determine the degree of aging and the degree of crack progression.

[0044] Next, the deterioration extraction unit (142) is a component that extracts deteriorated parts, such as white film, leakage, and spalling, from the tunnel image information. That is, the deterioration extraction unit (142) extracts deterioration phenomena occurring on the inner wall of the tunnel, other than cracks, from the tunnel image information.

[0045] Therefore, in this embodiment, it is preferable that the deterioration detection unit (142) detects lifting and peeling phenomena as thermal images among the tunnel image information.

[0046] Meanwhile, the report content generation unit (100) according to the present embodiment may be configured to include a tunnel specification identification means (110), a tunnel image information securing means (120A), a tunnel condition analysis means (140A), and a crack data insertion means (150), as shown in FIG. 11.

[0047] First, the tunnel specification determination means (110) is a component that determines the overall specifications of the tunnel while moving continuously from one side of the tunnel to the other, as described above. In order to quickly and accurately secure image information of the inner surface of the tunnel by the tunnel image information securing means (120A), the specifications, such as the height and width of all sections of the tunnel, must be accurately determined.

[0048] Next, the tunnel image information securing means (120A) is a component that secures three-dimensional image information by photographing a certain width of the inner surface of the tunnel at a specific location on one end of the two ends of the tunnel, based on the tunnel size information identified by the tunnel size identification means (110). In this case, the tunnel image information securing means (120A) is not installed on a moving means such as a vehicle, but is installed in a fixed state at a specific point of the tunnel to secure image information for a certain section of the tunnel, and then secures three-dimensional image information by moving to the next point and securing image information for the next section again.

[0049] Next, the tunnel condition analysis means (140A) is a component that analyzes the deterioration state of the tunnel by analyzing the three-dimensional image information obtained by the tunnel image information securing means (120A). Here, the tunnel condition analysis means (140A) is also a component that analyzes the deterioration state of the tunnel by analyzing the tunnel image information, as described above. That is, the tunnel condition analysis means (140A) diagnoses the deterioration state that may occur in the tunnel by analyzing the tunnel image information directly transmitted by the tunnel image information securing means (120A), and the specific analysis method is as described above.

[0050] Next, the crack data insertion means (150) is a component that overlays crack data analyzed by the tunnel condition analysis means (140A) onto the three-dimensional image information. As shown in FIG. 12, the shape overlaid with the crack data analyzed by the crack data insertion means (150) has a portion displaying crack data overlaid on the existing tunnel image information.

[0051] Next, the VR conversion means (160) is a component that converts the three-dimensional image information, overlaid with the crack data by the crack data insertion means (150), into VR content. The VR content converted by the VR conversion means (160) is provided to members through the report content sharing unit (300) as content that can be indirectly experienced through avatars.

[0052] Next, the database unit (200) is installed by connecting online to the report content generation unit (100) as shown in FIG. 1, and is a component that stores report content provided by the report content generation unit (100). That is, the database unit (200) stores report content provided by the fraud report content generation unit (100) by content, and performs the function of updating existing content when new content is provided to the content.

[0053] In addition, the database unit (200) also stores data provided by the report content sharing unit (300) for each data type.

[0054] Accordingly, in this embodiment, the database unit (200) can be configured to include a member information database (210), a facility-specific 3D image information database (220), a facility-specific report database (230), a VR content database (240), and a crack photo information database (250), as specifically illustrated in FIG. 1.

[0055] First, the member information database (210) is a component that stores member information of a member who can share the report content online through the report content sharing unit (100). The member information stored in the member information database (210) is used in the member authentication process by the report content sharing unit (100).

[0056] Next, the three-dimensional image information database (220) for each facility is a component that stores three-dimensional image information for each special facility. That is, the three-dimensional image information database (220) for each facility stores image information for each special facility, including image information taken to obtain specification information for each individual special facility and three-dimensional image information taken to evaluate the condition.

[0057] The 3D image information stored in this way for each facility is provided so that the image information can be shared with members authenticated by the report content sharing unit (300) above.

[0058] Next, the facility-specific report database (230) is a component that stores reports containing status evaluations and maintenance plans for each special facility. That is, the facility-specific report database (230) stores reports in the form of computer programs converted into PDF or similar formats when status evaluations and maintenance services for the relevant special facilities are performed.

[0059] The facility-specific reports stored in the facility-specific report database (230) are provided to be shared online with members authenticated by the report content sharing unit (300).

[0060] Next, the VR content database (240) is a component that stores VR content for each special facility. That is, the VR content database (240) stores video information in which crack data is superimposed on 3D video information for each facility, converted into VR content.

[0061] Next, the crack photo information database (250) is a component that stores crack photo information for each special facility. That is, the crack photo information database (250) stores facility-specific crack photo information obtained through condition evaluation and maintenance service work for each special facility, classified by the span of each facility.

[0062] Next, the report content sharing unit (300) is installed in connection with the database unit (200) as illustrated in FIG. 1, and is a component that shares report content stored in the database unit (200) with members online. That is, the report content sharing unit (300) shares requested information online with respect to various information stored in the database unit (200), but only with members whose membership status has been verified for each facility.

[0063] To this end, in this embodiment, the report content sharing unit (300) can be configured to include an information receiving module (310), a member authentication verification module (320), a content sharing module (330), and an information update module (340), as specifically illustrated in FIG. 1.

[0064] First, the information receiving module (310) is a component that receives report content information generated by the report content generation unit (100) and information stored in the database unit (200) through an information communication network.

[0065] Next, the member authentication verification module (320) is a component that verifies the member information of a member who wishes to access the report content sharing unit (300), registers the member, and then verifies the member status upon a login request. That is, the member authentication verification module (320) verifies the member information provided by the initial member to determine whether the member is allowed to access information for each facility, verifies the membership registration, and verifies whether permission is granted when the member logs in and requests information sharing, such as report content for each facility.

[0066] At this time, the member authentication verification module (320) preferably classifies member authentication by facility and verifies it separately in order to maintain security.

[0067] Next, the content sharing module (330) is a component that shares report content requested by a member who logs in, for a member whose membership status has been verified by the member authentication verification module (320).

[0068] Specifically, in this embodiment, it is desirable for the content sharing module (330) to share three-dimensional image information of the special facility as shown in FIG. 13, or to share deep zoom-in image information that provides a zoom-in image of a specific part of the three-dimensional image information as shown in FIG. 14, so that the status of each facility can be identified and verified without visiting the facility site.

[0069] In addition, in this embodiment, the content sharing module (330), as shown in FIG. 15, is desirable for individually sharing reports containing status evaluation and maintenance plans for special facilities, as this eliminates the need to create paper reports and allows for checking various field data for each facility online.

[0070] Next, the information update module (340) is a component that updates the report content information received by the information receiving module (310) for each database of the database unit (200). Explanation of the symbols
