Abstract
The utility model relates to a concrete surface crack width measuring label paster. The paster comprises a substrate. A standard width scale region and a two-dimension code information region are arranged on the substrate. Standard width scale coatings with different widths are arranged in the standard width scale region. Effective pixels in a digital photo are utilized as a transmitting quantity to compare the standard width scale to an observation crack and therefore the practical width of the crack is calculated. The defects of large work load and dangerous working environment of a traditional method are overcome, and high professional technology threshold, low resolution and the like existed in long-distance measurement based on a graphic processing technology are overcome. In addition, the paster employs the two-dimension code technology to store and identify information of a crack such as a position coordinate, an initial width and the like, the information storage identification efficiency is raised, and the storage content is increased.
Description
Technical field
The utility model belongs to the field of measuring technique of all kinds of concrete structural surface fracture widths in civil engineering work, is specifically related to a kind of concrete surface crack width measure mark paster.
Background technology
Width measure to concrete structural surface crack in civil engineering work, significant to judging structural stability and permanance.At present, conventional measuring method one is to use the instrument contact type measurements such as New Instrument for Crack Width, feeler gauge; The 2nd, based on the telemeasurement of graph processing technique.The parameter such as numbering, position of fracture often adopts marking pen, chalk to carry out mark.But this two class measuring methods exist respectively the disadvantages such as workload is large, working environment is dangerous and professional skill requirement is high, accuracy of identification is low, also there is the defects such as quantity of information is little, easy stained in crack labeling method simultaneously.Therefore, in this field in the urgent need to a kind of technology and equipment of the width of Quick Measurement fracture faces at a distance, simultaneously this technology accurately the information such as fracture position, original width, initial length, types of fractures carry out mark, and can allow line tunnel maintenance personnel grasp fast.
Utility model content
The purpose of this utility model is to provide one can realize concrete structural surface fracture width in remote Quick Measurement civil engineering work, and can fracture position, the information such as original width, initial length, types of fractures carries out mark, the concrete surface crack width measure mark paster of being convenient to fracture long term monitoring or repeatedly measuring.
For achieving the above object, the technological means that the utility model adopts is that a kind of concrete surface crack width measure mark paster, comprises substrate, substrate is provided with normal width groove district and 2 D code information district, is provided with the normal width groove coating of different in width in normal width groove district.
Preferably, the width of described normal width groove district internal standard width groove coating is respectively 0.2mm, 0.5mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm.
Described concrete surface crack width measure mark paster is measured and is known method for distinguishing, comprise the following steps: described concrete surface crack width measure paster is sticked near crack, then carry out longshot with digital camera, calculate the width in crack by the contrast shared pixel number in crack and the shared pixel number of normal width groove coating;
If the shared pixel count of the normal width groove coating of fracture width and a certain width is identical, fracture width and be corresponding normal width line width; If the shared pixel count of the normal width groove coating of the pixel count that fracture width is shared and a certain width approaches, adopt interpolation method and calculate according to following formula:
Wherein:
pX r ---the shared pixel count of fracture width;
pX n ---the shared pixel count of normal width groove coating that width is N;
w n ---the developed width of the normal width groove coating that width is N, the mm of unit;
w r ---fracture width, the mm of unit;
The information exchange of the original width in crack (width while measurement for the first time), initial length (length while measurement for the first time), position, type is crossed to Quick Response Code generating apparatus and generate Quick Response Code, then the Quick Response Code of generation is printed on to 2 D code information district by printer; Read original width, initial length, the position in the crack of recording on Quick Response Code, the information of type by Quick Response Code reading device.
The beneficial effect that the utility model produces is, utilize valid pixel in digital photo as transmission capacity, normal width groove coating and observation crack to be compared, thereby calculate and obtain crack developed width, both avoid the shortcoming that classic method workload is large, working environment is dangerous, avoided again the shortcomings such as the professional technique threshold existing based on the telemeasurement of graph processing technique is high, resolution is lower.Meanwhile, in the utility model, use the information such as planar bar code technology fracture position coordinates, original width to store identification, improved information storage recognition efficiency, increased memory space.
Brief description of the drawings

Fig. 2 is the use constitutional diagram of concrete surface crack width measure mark paster.
Embodiment
As shown in Figure 1, a kind of concrete surface crack width measure mark paster, comprises substrate 1, and substrate is provided with normal width groove district 2 and 2 D code information district 3, is provided with normal width groove coating 4 in normal width groove district 2.Described substrate 1 is aluminium-plastic panel substrate, the thickness of aluminium-plastic panel substrate is 4mm, on aluminium-plastic panel substrate, normal width groove district 2 is of a size of 60mm X 40mm (long X is wide), normal width groove coating 4 length are 30mm, and width is respectively 0.2mm, 0.5mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm; 4 printings of normal width groove coating adopt black or red ink, and wherein width printing precision is ± 0.1mm; Described 2 D code information district 3 is of a size of 40mm X 40mm (long X is wide).
Carry out longshot with digital camera (valid pixel is more than or equal to 1,200 ten thousand), calculate the width in crack by the contrast shared pixel number in crack and the shared pixel number of normal width groove coating; Initial length by the original width in the crack calculating with the crack measuring, and the information exchange of the position in crack, type is crossed Quick Response Code generating apparatus and is generated Quick Response Code, then the Quick Response Code of generation is printed on to 2 D code information district 3 by printer, as shown in Figure 2.
Can read original width, initial length, the position in the crack of recording on Quick Response Code, the information of type by Quick Response Code reading device, can fracture long term monitoring or repeatedly measure.
