Abstract
The utility model discloses a concrete crack field detection and imaging device. The concrete crack field detection and imaging device includes a calibration frame, a support, a digital camera, a dyeing sprayer and baffles; the calibration frame is pasted on concrete; the outer side of the calibration frame is provided with the dyeing sprayer; the dyeing sprayer and the digital cameras are both fixed on the support; the bottom of the support is provided with moving rolling wheels; and the outer periphery of the calibration frame is provided with the baffles which can prevent the exterior of the calibration frame being dyed. According to the concrete crack field detection and imaging device of the utility model, image processing techniques are utilized to measure the width of a surface crack of a structural object, which is a nondestructive testing method; according to the method, only an ordinary digital camera is needed to acquire one image of the crack, so that the width of the crack can be determined. The concrete crack field detection and imaging device has the advantages of small interference on the measured structural object, high simplicity and easiness in implementation.
Description
Technical field
The utility model relates to distress in concrete detection technique field, be specifically related to a kind of distress in concrete Site Detection and imaging device.
Background technology
The xoncrete structures such as bridge, house, road, due to the effect of the various loads in design, construction and use procedure, all can produce crack, and the width in crack and length have reflected the duty that structure is current.In the time that the width in crack is excessive, will affect its aesthetic property, permanance and even jeopardize the security of structure.Therefore the width of periodic monitor works surface crack is one of important content of works detection
Traditional method based on artificial vision's fracture detection more and more can not adapt to bridge detect development requirement, be mainly because speed is slow, individual subjective degree is large, and spend high, danger.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of distress in concrete Site Detection and imaging device, utilizing image processing techniques to measure works surface crack width is a kind of lossless detection method, the method only needs an ordinary digital camera to gather the image in a width crack, can determine the width in crack, little to tested works interference, equipment is simple, is easy to realize.
To achieve these goals, the utility model is to realize by the following technical solutions: distress in concrete Site Detection and imaging device, comprise and demarcate frame, support, digital camera, dyeing shower nozzle, baffle plate, demarcating frame sticks on concrete, demarcating frame arranged outside has dyeing shower nozzle, and dyeing shower nozzle and digital camera are all fixed on support, and frame bottom is provided with shifting roller, demarcate frame outer ring and be provided with baffle plate, prevent that dyeing is to demarcating outside frame.
As preferably, described baffle plate is pegged graft with demarcating frame, after dyeing completes, removes baffle plate, and carries out image acquisition by digital camera.
It is a kind of lossless detection method that the utility model utilizes image processing techniques to measure works surface crack width, the method only needs an ordinary digital camera to gather the image in a width crack, can determine the width in crack, disturbs little to tested works, equipment is simple, is easy to realize.
Brief description of the drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, this embodiment is by the following technical solutions: distress in concrete Site Detection and imaging device, comprise and demarcate frame 1, support 2, digital camera 3, dyeing shower nozzle 4, baffle plate 5, demarcating frame 1 sticks on concrete, demarcating frame 1 arranged outside has dyeing shower nozzle 4, and dyeing shower nozzle 4 and digital camera 3 are all fixed on support 2, and support 2 bottoms are provided with shifting roller, demarcate frame 1 outer ring and be provided with baffle plate 5, prevent that dyeing is to demarcating outside frame.
It should be noted that described baffle plate 5 and demarcate frame 1 and peg graft, after dyeing completes, removing baffle plate 5, and carry out image acquisition by digital camera.
In addition, described support 2 is for possessing the tripod that has levelling function.
This embodiment bridge, the isostructural surface crack width in house are generally less, and fracture width direction shared pixel in digital image is also less, and therefore the acquisition quality of image can have influence on last accuracy of detection.In order effectively to improve the accuracy of fracture width identification, should adopt the digital camera of high pixel, make crack on Width, obtain more pixel.When shooting, hand-held digital camera, in crack and the dead ahead of demarcating paper, makes crack in center Screen position as far as possible, and becomes vertical state, adopts positive burnt (camera lens vertically oriented fracture plane) to take and reduces distortion.Therefore need constantly slightly to regulate the inclination angle of camera, observe crack plane in magazine imaging, make as much as possible crack plane vertical with camera optical axis, crack should be the widest in magazine imaging.This embodiment adopts to possess has the support of levelling function etc. to fix camera, to obtain better image acquisition quality.
It is a kind of lossless detection method that this embodiment utilizes image processing techniques to measure works surface crack width, the method only needs an ordinary digital camera to gather the image in a width crack, can determine the width in crack, disturbs little to tested works, equipment is simple, is easy to realize.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
