Description
Technical field
The utility model is related to a kind of apparent check devices of bridge, belong to bridge inspection and maintenance field.
Background technology
Recently as economic rapid development, highway communication flow dramatically increases, well beyond design discharge will
It asks, increases the spoilage of highway bridge, maintenance cycle reduces.Due to Bridge position dispersion, build the age is different, build when make
Technical standard is different, the difference of bridge structure form, and the operating conditions of road network Bridge is caused to there is very big difference.Bridge
The workload of beam inspection also greatly increases.
According to《Highway bridge and culvert Maintenance specification》Regulation, bridge inspection are divided into running check, inspect periodically, special examined.Needle
It to bridge running check and inspects periodically, the prior art is mostly with reference to specification, using estimating or be equipped with simple tool and instrument, needle
To different bridge types, across footpath, headroom, using different ancillary equipments, such as double ladder, bridge-checking vehicle, existing disease is recorded,
And disease is photographed to record using camera.
According to《Highway bridge and culvert Maintenance specification》Regulation, the every month in period of bridge running check must not be less than once, periodically
Inspection cycle determines that longest must not exceed 3 years according to technology status.Newly building bridge was delivered for use after 1 year, carried out complete for the first time
Face checks.Temporary bridge checks no less than primary every year.And it is increasing with bridge quantity in recent years, workload gradually adds
Greatly, the prior art is in bridge inspection, and one is checked using double ladder, and limitation is larger, and landforms are complicated under bridge, difficult in many cases
To set up double ladder, the range that can be observed on ladder is also extremely limited, needs constantly to move ladder, to ensure completion pair
The whole of bridge checks that workload is heavy, less efficient.Two for bridge-checking vehicle, and it is higher to be only applicable to headroom, nothing around bridge
It is used in the case of shelter, and needs to rest on smooth firm ground or works, for some semi-filling and semi-excavating roads
Bridge, the brushy bridge of surrounding of section, the use of bridge-checking vehicle are just restricted.
In addition in terms of economy, practicability, safety, bridge-checking vehicle investment is larger and larger support is needed to put down
Platform, the safety that driving road surface must also have large area enclose the measure of keeping away.Two use double ladder, and the double ladder used at present is mostly 2
In rice to 5 meters of altitude ranges, headroom will be unable to be checked more than 6 meters or so, and ladder erection is higher, landforms are more multiple under bridge
Its miscellaneous safety is greatly reduced.
Finally, photo is analyzed after being shot in the prior art using camera, is often gone wrong during analysis,
For example subtle crack and trace can not be told, it goes wrong so as to cause inspection result, these are all that existing camera is clapped
Take the photograph the problem of technology institute restriction band is come.

In the further preferred embodiment of the utility model, it is necessary first to which explanation in the utility model, uses photograph
Bright lamp carry out floor light be not limited to ambient light it is bad when, it is equally possible when daytime is sunny to need to use
Floor light is carried out to headlamp.It was found that for the subtle crackle in bridge surface and by black or brown material in bridge
The trace that surface is formed is sometimes difficult to make specific differentiation, and in order to correctly be distinguished to this, it is thin to improve bridge surface
The discrimination power of micro-crack, according to the utility model, the brightness of headlamp is adjustable, can not only realize that common floor light is made
With picture more being caused to reach saturation exposure by adjusting the brightness of headlamp, and improve blind crack on this basis
Discovery rate.Specific image pickup method includes the following steps：
Step 1: carrying out the apparent picture shooting of bridge, picture is scanned on the receiver in real time；
Step 2: there are during subtle black lines namely light intensity is significantly lower than neighboring area in sending out existing picture above-mentioned
Tiny black region, the brightness of adjusting illuminating lamp so that at least one pixel reaches saturation exposure on photo captured by camera；
It, will picture corresponding with the subtle black lines Step 3: the image of the interception subtle black lines region
The light intensity value of element is compared with certain pre-stored predetermined value, if the light intensity value of the pixel is less than the predetermined value,
Black lines on picture are defined as doubtful crackle and continue step 4, step 1 is then gone to if greater than the predetermined value,
Shoot the apparent picture of bridge other positions；Certain wherein described predetermined value can be right by what is formed on bridge surface under equal illumination
Bridge generates the picture light intensity value corresponding to the crackle captured by the minimum cracks of harm；
Step 4: it carries out zoom by the camera and is directed at the doubtful crackle on the bridge to be shot again so that
The doubtful crackle at least occupies 5 pixels in the direction of the width, and the light intensity value for then analyzing five pixels in width direction becomes
Change, if the variation of its light intensity value is descending then ascending, then the doubtful crackle is determined as crackle, if its light
Intensity values show as basically identical, it is determined that the doubtful crackle is trace.
Search in wherein described step 1 can be performed by computer, also can be by manually performing namely primarily determining on picture
It is not determined as the black lines of blind crack or trace；
It is carried out in step 2 so that at least one pixel achievees the purpose that saturation exposure is in order to by the black lines area
The light exposure in domain reaches maximum, and saturation exposure can be reached by least one pixel on photo to judge, works as exposure
When amount reaches maximum, be then conducive to the progress of subsequent step, and light exposure can generally be conducive to greatly the interpretation of result accuracy.
Step 3 is that the black lines are further judged, for blind crack, crackle is deeper, then it is clapped
The light intensity for taking the photograph crackle corresponding position after photo is smaller, so can be by being compared to exclude with that can generate the minimum crackle of harm
All crackles not constituted a threat to, so as to can not only further determine that blind crack as a result, and can largely save follow-up
Calculation amount；
Step 4 kind, it is however generally that, crackle is generally all presented v-shaped structure namely is open at surface greatly, with depth
Increase, be open and tapering into, show a v-shaped structure on the whole, the light intensity that such structure generates on picture also can
As change in depth shows corresponding variation namely from big to small, then from small to large, and for trace, since it is
Be made of black or brown material, thus its on the whole for light intensity be not in above-mentioned variation in the direction of the width, light intensity
Value will not generate large change substantially in the direction of the width.
Illustrating just for the utility model above, but can not be construed as a limitation of the present invention.
The deformation of those skilled in the art's precognition is in the scope of protection of the utility model.
