Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a ground subsidence diagnosis system using CCTV data of a sewer line and GPR data of an upper ground,

More particularly, the present invention relates to a system for diagnosing a subsidence in a sewer pipe upper ground, and more particularly, it relates to a system for diagnosing a subsidence in a sewer pipe upper ground by examining drainage, cracks, breakage, The present invention relates to a ground subsidence diagnosis system and method using CCTV data of a sewer line and GPR data of an upper ground, which is used for predicting and evaluating subsidence due to a sewer line by exploring a ground penetrating radar (GPR).

Generally, in order to confirm the internal state of the pipeline buried in the underground, an image acquisition device, for example, CCTV, is mounted on the navigation cruiser that travels inside the channel, A scanning device for receiving and analyzing images has already been introduced and used.

Such a surveying apparatus is disposed in a pipe for transporting various liquids, gases, and slurries. When the inside of the pipe is photographed by using a camera and an illuminating device mounted while moving inside the pipe, and the photographed image is transmitted by wire or wireless, And determines whether or not a defect is present. For example, a sewer pipe exploration device acquires the shape of a sewer pipe while driving a cruise control car capable of CCTV measurement into the sewer pipe. Such a sewer pipe exploration device is a method of video recording of the inside of a sewer pipe using CCTV. The user watches the forward and the side of the abnormal part according to the judgment of the user, captures the abnormal part and creates a report, The grade of the above points can be calculated. Such a sewer pipe exploration device can perform only visible judgment such as relaxation of the joint portion in the sewage pipe and sedimentation of the soil.

FIG. 1 is a view schematically showing a surveying apparatus by a front view according to a conventional technique.

As shown in FIG. 1, in the case of a forward-looking surveying apparatus according to the related art, a camera 20 mounted on the front side of the washing crucible 10 while moving through the sewage line 30 moves the sewage line 30 ) Is taken as an image.

Since the surveying apparatus is advanced while observing only the front side, it is not possible to accurately determine the damage state or the change state of the surface of the inside of the sewage pipe 30, and the focus position of the camera 20 is not located at the center, It is difficult to accurately diagnose the situation of the sewage line 30 because the image values of the upper and lower portions of the acquired image data are not constant.

FIG. 2 is a view schematically showing a conventional scanning apparatus including a fish-eye lens.

As shown in FIG. 2, in the case of a conventional scanning apparatus equipped with a fish-eye lens, a navigation system 10 disposed at the center of the sewer line 30; A camera (20) mounted on the front of the navigation device (10); And a convex fisheye lens 40 coupled to the front of the camera 20. Although the method of acquiring an image in the range of about 180 degrees through the fisheye lens 40 and then expanding the received image data is used in the exploration apparatus having such a fisheye lens, Since a wide range of images are acquired by attaching the image processing unit 40 to the image processing unit 40, the image processing unit 40 includes an unnecessary region. In particular, the image is severely distorted. Accordingly, There is a problem in that it must be processed.

As described above, in the case of the surveying apparatus according to the conventional art, only the front side is observed, or the image of the wall surface of the channel is taken by simply combining the fish-eye lens so that the photographed image on the inner surface of the channel is distorted, There was a problem.

On the other hand, as a prior art, Korean Patent No. 10-939529 discloses an invention entitled " system for simultaneous exploration and analysis on the inside and outside of a pipeline ", which will be described with reference to FIGS. 3 and 4. FIG.

FIG. 3 is a view showing that the pipeline simultaneous exploration analysis system according to the prior art is implemented as a navigation cruise control system, FIG. 4 is an execution view of the survey analysis program of the pipeline simultaneous exploration analysis system shown in FIG. 3 A full image of each of the inner and outer surfaces of the channel, a front image of the area having the abnormal item, a side image, an enlarged image, and an image of the tube outer surface.

Referring to FIG. 3, a conventional pipeline simultaneous exploration / analysis system is a system for exploring the state of a buried underground pipe. The system includes a probe 51, an image acquisition unit 52, a ground penetrating radar 53, an encoder 54, a computer 55, and an optical cable 56.

The drive motor 51 is mounted on the side of the inner side of the duct.

The image acquiring unit 52 is provided with a lens adapter and a digital camera which are installed at the front end of the driving motor 51 to simultaneously acquire the front and side images of the inner surface of the duct.

A Ground Penetrating Radar (GPR) 53 is installed on the upper portion of the vehicle 51. Here, the ground penetrating radar 53 can receive electromagnetic waves to receive electromagnetic waves, analyze the signals according to the medium, and detect submerged or underground cavities such as sewage, waterworks, power pipes, cultural properties buried underground.

The encoder 54 is installed on one side of the ground penetrating radar 53 so as to be in close contact with the upper surface of the conduit when the traveling trolley 51 runs on the inner surface of the conduit, Measure the distance. By accurately measuring the travel distance using the encoder 54 as described above, it is possible to compare the image of the inner surface of the pipe at the same position with the image of the outer surface of the pipe.

The computer 55 includes a field trial program for collecting and storing the image data acquired by the image acquisition unit 52 and the electromagnetic wave data acquired from the ground transmission radar 53, Analysis, and analysis programs that integrate, edit, and analyze data. At this time, the field-sampling program built in the computer 55 presents a tree structure organized by channel numbers on the monitor, and information on channel specifications corresponding to the channel numbers is retrieved from pre-stored Excel data.

The optical cable 56 is connected between the computer 55 and the navigation device 51 so as to transmit the data collected by the navigation device 51 to the computer 55.

4, the survey analysis program is equipped with an image gallery tool that performs editing by designating an area having an abnormal item in one entire image of the inner surface of the duct, The side image and the enlarged image can be displayed at the same time. At this time, the unnecessary data can be deleted again while reviewing the selected ideal item area. In addition, the survey analysis program can identify the structure and condition of the lipid and the underground structure of the external surface of the pipe by analyzing the electromagnetic wave data acquired by the ground penetrating radar 53 and collected and collected by the field survey program.

In the case of the pipeline simultaneous exploration analysis system according to the related art, the image acquisition unit 52 is installed at the front end of the tamper-evident vehicle 51 to simultaneously acquire the front and side images of the inner surface of the pipeline, The ground penetrating radar 53 is installed on the top of the tamper-evident vehicle 51 so as to identify the structure and state of the lipid and the underground structure of the outer surface. Accordingly, the front and side images of the inner surface of the pipe, The structure and state of the structure can be identified and imaged, and the inside and outside surfaces of the pipeline can be superimposed and read out by accurate distance measurement.

However, in the case of the conventional pipeline internal / external surface simultaneous analysis system, since the ground penetrating radar 53 is installed in the upper part of the cruise control main body 51 in the sewer pipe, the efficiency of equipment operation is lowered There is a problem. In addition, the existing GPR method has a problem that the precision of leakage, crack, and pupil measurement around the sewer pipe is inferior, and in particular, it is difficult to superimpose the obstacles and to measure the periphery of the lower part of the sewer pipe.

Meanwhile, the sewer line CCTV survey according to the conventional technique is a method for measuring the state of pipes and defects by entering the equipment equipped with a camera into the pipe, and observing an abnormality occurring in the sewage pipe such as leakage, crack, And determine repair and reinforcement methods. For example, if the fault in the sewer pipe deteriorates, the structural defects will gradually become obsolete and, in the worst case, the sewer pipe will be destroyed, causing ground subsidence or road depression.

Such a sewer pipe CCTV inspection can detect the defect in the sewer pipe, but there is a problem that it is difficult to confirm whether the ground subsidence or the pupil of the sewer pipe which is a problem at present is present. In fact, cracks in the sewer pipe, soil inflow due to damage, loosening and sinking of the ground around the sewer line due to leakage, and whether or not the pupil is causing the subsidence (sinking). In addition, there is a problem of sink hole formation due to the ground pores in the vicinity of the sewer line. Therefore, in order to prevent the subsidence due to the sewer line, it is necessary to investigate the ground deformation that may occur in the sewer pipe defects.
