Description
Technical field
The invention belongs to municipal infrastructure project field, specially a kind of Crack Detection side of piping lane concrete structure
Method.
Background technology
Piping lane is the parking space of all kinds of comprehensive pipelines of Urban Underground (water, electricity, warm, communication etc.), with social economy
Gradually development, urban land is more and more nervous, reasonable development and be the important directions of construction of future cities using the underground space.Pipe
The construction of corridor is advantageous to the rational deployment of all kinds of pipelines, and prolonged operation maintenance, thus in recent years China built it is more
The city integrated piping lane of bar.
Piping lane typically uses reinforced concrete structure, because construction, load, temperature change, differential settlement, concrete are received
The factors such as contracting, when the deformation energy inside concrete material is excessive, macrocrack will be produced, reduces the durability and safety of structure
Property, bring great hidden danger.Therefore, in construction and O＆M stage, the detection in piping lane crack, for its quality control and maintenance side
The selection of method, all it is vital.
The content of the invention
To improve the detection efficiency of piping lane distress in concrete, the present invention proposes a kind of detection side using graphical analysis as means
Method.IMAQ is carried out to piping lane first, the processing such as is then filtered, sharpens, strengthen with computer, afterwards progress slit width meter
Calculate, and with ultrasonic pulse method detect the penetration of fracture, finally collect crack information for the maintenance of fracture unit and piping lane provide according to
According to.
To achieve the above object, the present invention provides a kind of detection method in underground pipe gallery crack, and piping lane is entered first
Row IMAQ, the processing such as then it is filtered, sharpens, strengthening with computer, carries out slit width calculating afterwards, and use ultrasonic pulse
Method detects the penetration of fracture, finally collects crack information, comprises the following steps：
Step 1, the piping lane there may be crack is taken photo by plane using unmanned plane, and the image collected is inputted and counted
In calculation machine；
Step 2, utilize computer disposal crack pattern picture；
Step 3, to treated crack pattern picture, according to the Pixel Information of fracture width and piping lane width in figure, with reference to
Known actual piping lane width, pro rata calculate actual fracture width；
The location of step 4, global coordinate is established, determined according to crack pattern picture per crack center, use at the scene
Ultrasonic pulse method detects the penetration of fracture；
Step 5, the information such as the position in whole cracks, width, depth are collected, complete detection.
Preferably, for the image collected, the gray value of computer extraction image is utilized.
Preferably, wavelet transformation is carried out to image, to HFS threshold denoising, then carries out Wavelet image reconstruct.
Preferably, rim detection is carried out using Laplace operator fracture image.
Preferably, image enhaucament is carried out using histogram equalization method.
As can be seen from the above technical solutions, compared with prior art, present invention has the advantages that：
IMAQ is carried out to piping lane using unmanned plane, the flexibility ratio of Collecting operation is improved, saves manpower and materials, greatly
The big efficiency for improving information gathering；Image analysis process can realize that program has good transplantability with computer programming, can nothing
Limit time uses, and detection method automation, intellectuality, testing result is accurately and reliably.
Brief description of the drawings
Fig. 1 illustrates the implementing procedure figure of the present invention；
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with, to the present invention enter advance
One step describes in detail.It should be appreciated that it is described herein specific only to explain the present invention, it is not intended to limit the present invention.
The application principle of the present invention is further described below in conjunction with the accompanying drawings and specifically：
As shown in figure 1, a kind of detection method in underground pipe gallery crack, implementation process include following steps.
First, piping lane IMAQ.The piping lane there may be crack is taken photo by plane with unmanned plane, the image that will be collected
Input in computer.
Second, piping lane image is handled.Because detection crack information does not need coloured image, first to image zooming-out
Gray value, it is stored as two-dimensional matrix；Then wavelet transformation is carried out to the matrix, threshold denoising is carried out to HFS, reduces figure
As noise, then carry out Wavelet image reconstruct；Then rim detection is carried out to image with Laplace operator, due to crack both sides figure
The brightness of picture has mutation, it is possible to detects edge of crack；Finally image enhaucament is carried out with histogram equalization method.
3rd, to by handling and the crack pattern picture of enhancing, according to fracture width and piping lane width (Pixel Information) in figure,
With reference to known actual piping lane width, pro rata calculates actual fracture width.
The location of 4th, global coordinate is established, determined according to crack pattern picture per crack center, at the scene with super
Ping method detects the penetration of fracture.
5th, according to information such as the position of every crack, width, depth, collect the crack full detail of piping lane, be piping lane
Maintenance provides reference.
By the application of the inventive method, the Crack Detection of piping lane concrete structure can be efficiently realized, for crack
Mending option and the maintenance of the piping lane in O＆M stage play the role of positive, and the inventive method can improve informationization technology and build
The application of engineering is built, is worth in industry promoting.
It should be noted that herein, term " comprising ", "comprising" or its any other variant are intended to non-row
His property includes, so that process, method, article or equipment including a series of elements not only include those key elements, and
And also include the other element being not expressly set out, or also include for this process, method, article or equipment institute inherently
Key element.In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that including institute
State in process, method, article or the equipment of key element and other identical element also be present.
Described above is only the embodiment of the present invention, is made skilled artisans appreciate that or realizing this hair
It is bright.A variety of modifications to these will be apparent to one skilled in the art, as defined herein general former
Reason can without departing from the spirit or scope of the present invention, in other middle realizations.Therefore, the present invention will not be limited
In it is shown in this article these, and be to fit to the most wide scope consistent with principles disclosed herein and features of novelty.
