Description

TECHNICAL FIELD [0001] The present invention relates to a device for measuring cracks in a smart phone,
The present invention relates to a structure crack measuring apparatus, and more particularly, to an apparatus for measuring a crack of a structure based on an image photographed by a camera, comprising: a smart phone having a crack- To a smartphone-coupled structure crack measurement device for assembling a fixture and a smartphone case in a cracked state in order to combine the smartphone and the smartphone case together.
Generally, if the structure is affected by vibration or subsidence, cracks are likely to occur. If such cracks become severe, the risk of collapse of the structure will be increased. Therefore, safety check should be periodically performed to measure changes in crack width.
BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a view illustrating a crack width measuring instrument according to a conventional technique.
FIG. 1 shows a crack width measuring instrument (or a measuring card) for measuring a crack width of a structure. The crack width measuring instrument 10 has a rectangular transparent plate shape having a thin thickness. . Therefore, the crack width can be measured by placing the crack width measurer 10 on the crack region 20.
However, the crack width measurer 10 according to the conventional technique is not only difficult to accurately measure minute cracks, but also requires a separate lighting device in a dark place.
On the other hand, in general, when performing precise survey work such as concrete crack measurement of a building to be constructed when a construction work is performed at a construction site, a concrete lens crack detector is provided with a magnifying lens A crack is used.
For this kind of inspection work, we used a magnifying lens to inspect the cracked area and then measure the degree of cracking again by measuring a straight line or a tape measure. In addition, when the inspection operation is carried out at night or in a dark building, the measurement state of the crack is recorded under dark internal illumination in order to precisely check the measurement state of the crack. And the accuracy of the measurement value is deteriorated. As a result, the efficiency of the detection operation is lowered.
2 is a view showing a crack width for crack width measurement according to a conventional technique.
2, the crack light 30 for measuring the crack width according to the prior art includes an enlarged lens body 31, a magnifying lens 32, a scale portion 33, and a lighting device 34 do.
The crack width of the structure can be measured by forming the scale portion 33 on the enlarged lens 32 in the case of the crack light 30 for measuring the crack width according to the conventional technique, There is a problem in that it is difficult to grasp the crack width of the structure accurately through the scale part 33. [
On the other hand, since microcracks may appear in structures such as buildings, bridges, and tunnels, safety assessments are regularly conducted to evaluate the degree of damage and stability of structures. For example, it is difficult to precisely diagnose a safety diagnosis by the operator, and even if a crack measurement gauge is used as a crack inspection equipment, it is difficult to manage the measurement data, so that the captured image can be analyzed A crack inspection apparatus is preferred.
There has been used a method of observing the image taken by the crack inspection apparatus according to the conventional technique and recording the measured value obtained by converting the degree of cracking of the structure into a numerical value to grasp the progress of the crack. In the case of the crack inspection apparatus according to the conventional technique, since the image magnification obtained by the photographing equipment differs from the actual image, the crack size shown in the shot image may be different from the actual measurement value. Therefore, And the measured value of the cracked portion of the photographed image is calculated based on the measured value, and the detected value is input to the input device.
The crack inspection apparatus according to the related art directly measures the actual measurement value by the operator and thus it is troublesome to perform the measurement of the actual measurement value and also it takes a lot of time to convert the crack portion shown in the captured image into the actual measurement value .
Also, in order to prepare for the case where the cracks of the structure proceed from relatively early in the initial stage, it is necessary to continuously monitor the cracks, and a function of efficiently managing the measurement data for such cracks is required.

[
The housing 41 surrounds the image acquisition camera 45, the illumination device 46 and the magnifying lens 44 to keep the measurement distance of the image acquisition camera 45 constant so as to enable a quantitative conversion of the crack width.
The knob 42 is a handle that facilitates portability, and an image acquisition switch 43 and a screen display unit 47 are attached.
The memory 48 and the CPU operation unit 49 are embedded in the handle 42 for storage of the acquired image, image processing, and calculation of the crack width.
The magnifying lens 44 allows enlargement and reduction by a constant magnification in order to facilitate measurement of a minute crack.
The image acquisition camera 45 is embedded in the handle 42 to acquire an image and the illumination device 46 facilitates measurement even in a dark place such as a tunnel and provides light to secure resolution of the photographed image data And the screen display unit 47 displays the calculated crack width in a digital value.
The portable crack measuring apparatus 40 using the image processing technique according to the related art is capable of not only acquiring image data of a crack by the operation of the image acquiring switch 43, Can be automatically calculated / stored, providing fast, systematic and objective inspections regardless of the skill of the tester.
However, in the case of the portable crack measurement apparatus 40 using the image processing technique according to the related art, the image capture camera 45, the screen display unit 47, the memory 48, and the CPU operation unit 49 are separately manufactured There is a problem in that it is expensive in terms of cost and complex in implementation.
