12000000 pixels；End of taking pictures obtains crack photo；
5, the photo of shooting is extracted, and placed in a computer, using image processing software to the crack of acquisition
Photo carries out image procossing, and image processing software is Image Pro Plus, first opens Image Pro Plus softwares, then open
The crack photo of shooting；Then it sets scale, opens measurement-calibration-spatial calibration dialog box, create calibration title, click the
One image, enlarged photograph drag and carry out selection scale on the green scale to the graduated scale of crack photo occurred in photo
Length inserts physical length in scaling dialog boxes, when selecting the length of 10mm on graduated scale, talks in scaling
10 are inserted in frame, clicks ok, are returned again to spatial calibration dialog box and are clicked apply, close box, scale setting is completed；Then
Rectangle AOI tools are clicked, frame selects crack area in photo, creates AOI, when rift portion in the photo of crack and other parts aberration
When comparing unobvious, contrast enhancing operation can be carried out, in order to identify edge of crack；Editor-duplication/clipping tool is selected,
Generate crack area picture；Measurement-automatic measurement/counting is opened, measurement parameter is set in the measurements, including area and length,
Editor-draw/merge objects are selected, range and smooth numerical value is set, using automatic tracing or magic stick identification of function
The edge in crack creates AOI, and when the marginal existence deviation in the crack of automatic identification, edge of crack is set using manual trace
Create AOI；It completes after creating AOI, program can be calculated automatically, correlation calculation result be checked in view, including obtain
The area A and length L of region internal fissure, are calculated We, formula is by formula：We=A/L；
When needing to be monitored, by detection device pressing in the marked region of crack wall, then repeats shooting and split
Stitch photo and analysis crack photo to get to monitoring data, pass through the comparison of monitoring data, you can the variation of fracture make compared with
Accurately to judge.
Above-mentioned length L is the straight length at region internal fissure both ends, and the crack in Practical Project is simultaneously non-fully linear,
But it is close to straight line in a certain range.The length of curve in crack can be measured by increasing image procossing, it is long with curve
Degree etc. is all straight length, although having deviation using the result that length of curve replaces straight length to be calculated, compared to
It is negligible for the error of traditional detection method itself.And what this method was finally calculated is equivalent width
The specific width of degree rather than a certain measuring point improves working efficiency, obtained fracture number so as to simplify image processing process
According to can more embody crack actual conditions.
In order to improve the data accuracy of monitoring, monitoring platform is transferred data to using sensor and wireless transmission, with
Achieve the effect that monitor in real time, the building in the neutral gear for detecting and monitoring is avoided substantive and irreversible injury occur；Wherein

Gradient；Monitoring terminal is laid, monitoring terminal is the fracture width sensor being connected with NB-IOT wireless transport modules, inclination angle biography
Sensor, hydrostatic level etc.；Wherein fracture width sensor is used to measure the change width situation of monitored wall body slit, lays
Maximum width in surveyed crack；Obliquity sensor is used to measure the gradient situation of change of surveyed wall, is generally laid in
On the larger bearing wall of gradient；Hydrostatic level lays several for measuring building settlement situation according to house build
At the same absolute altitude of house surrounding, it is observed using the principle of connection liquid；The sensor has been wirelessly transferred with NB-IOT
Module is integrated, self-powered, need not also connect up transmission signal, install convenient.Monitoring terminal carries out data by the frequency of setting and adopts
Collection, long-range monitoring platform is sent data to by NB-IOT networks.NB-IOT network services are provided by network operator；Monitoring
Platform is analyzed and is handled to monitoring data, and prison is checked in PC computer ends or communication terminal APP implementations by internet
Measured data.
According to house investigation or qualification result, fracture width, gradient and settling amount threshold are set in a data processing system
Value；When fracture width, gradient and the settling amount acquired is more than the threshold value of design, monitoring platform passes through internet or movement
Communication network sends alarm or short message to pc computer ends and communication terminal.After receiving warning message, Yong Huan
Drainage technique personnel confirm monitoring terminal operating situation, and whether there is or not other environmental impact factors for understanding to the field reconnaissance of house scene.
As really changed for this body structure of house, then building safety situation is further assessed, emergency trouble shooting measures is taken when necessary, reaches
To more safe and reliable construction.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art on the basis of the present invention made by equivalent substitute or transformation, in the present invention
