Description

Distance setting device for structure shooting {SPACER FOR STRUCTURE PHOTOGRAPHY}

The present invention relates to an auxiliary device for photographing, which sets a constant distance between a smartphone 10 and a subject in photographing performed during diagnosis and inspection of various structures, and is attached to a case 20 to which the smartphone 10 is coupled. By installing a pair of support plates 30 and extension plates 40 that protrude, and shooting in a state where the tip of the support plate 30 or extension plate 40 is in close contact with the surface of the subject, the shooting distance is set constant.

Photographing of a structure is a basic work that is performed first and foremost along with a visual inspection by an inspector in safety diagnosis and inspection, etc. Various phenomena that can be confirmed externally, such as cracks, peeling, peeling, etc., as well as deformation and deterioration formed on the subject It can be useful in identifying and recording.

On the other hand, as high-resolution digital cameras are miniaturized and lightweight with the development of digital camera technology, small digital cameras are actively used even in structure photography, and related prior art includes Patent No. 2157308.

Conventional equipment for photographing structures, including Patent No. 2157308, focuses on the ease of close-up photography of high-rise structures, etc., and has a disadvantage in that it is difficult to miniaturize and lighten as well as have a complicated configuration.

In particular, since the photographing distance of the camera, that is, the distance between the objective lens of the camera and the subject cannot be grasped at all after or in advance, there is a serious problem in that the actual size of the subject cannot be confirmed in the photographed picture.

Therefore, a method in which a separate target with dimensions is prepared is prepared, and a worker other than the inspector who performs the photographing takes a picture so that the target is included in the picture in a state where the target is closely attached to the subject. At least two people had to perform the filming of the structure, which required confirmation of the actual dimensions.

Accordingly, a method of shooting with a target attached to the surface of the subject is also applied so that one person can work, but in this case, the work of attaching the target before shooting and removing the attached target after shooting is required, which delays the work time. In addition, a serious problem of damage to the subject in the process of attaching and detaching the scale was inevitable.

In particular, unlike detailed inspections in which a large number of personnel are mobilized according to a pre-established plan and schedule, using various instruments and exploration equipment, or by taking samples, exterior inspections need to be routinely performed by a single inspector. Bar, it can be said that miniaturization, light weight, operation and portability of shooting equipment, which is a key recording means of appearance inspection, are urgently required.

In view of the above-mentioned problems, the present invention can grasp the dimensions of a subject in a captured image by setting a constant shooting distance while using a conventional smartphone 10, which is easy to carry and has a familiar operation method, as a photographing device for external inspection. In the distance setting device for structure imaging, an opening 21 is cut in the case 20 coupled to the smartphone 10 so that the camera 15 of the smartphone 10 can pass through the opening 21 Exposed through and bonded to the surface of the case 20 on both sides of the opening 21, the support plate 30 protruding toward the subject is bonded, and a long hole 31 is cut and formed at the end of the support plate 30 on the bonding side of the case 20. An annular coupling groove 33 with one side open is formed at the other end, and an extension plate 40, which is a columnar plate, is coupled to the support plate 30, and the support shaft ( 41) is formed, and a detachable shaft 43 is formed at a position spaced from the support shaft 41 toward the center of the expansion plate 40, so that the support shaft 41 is freely movable in the long hole 31. The diameter of the support shaft 41 and the width of the long hole 31 match, the diameter of the detachable shaft 43 and the width of the coupling groove 33 match, and the distance between the support shaft 41 and the detachable shaft 43 is the long hole Matching the distance between the rear end of the case 20 side of (31) and the coupling groove 33, in a state where the support shaft 41 is located at the rear end of the long hole 31, the detachable shaft 43 is attached to the coupling groove 33 It is a distance setting device for structure imaging, characterized in that the extension plate 40 is fixed to the support plate 30 as it is coupled.

In addition, in the present invention, the side plate 36 protruding outward is formed at the joint between the support plate 30 and the case 20, the binding shaft 37 is formed at the distal end of the side plate 36, and the extension plate 40 Between the support shaft 41 and the detachable shaft 43, a coupling groove 47 is recessed, and the coupling groove 47 moves along the coupling shaft 37 in a state in which the extension plate 40 is rotated to the side of the case 20. It is a distance setting device for structure shooting, characterized in that the extension plate 40 is fixed and the other end of the case 20 of the support plate 30 is exposed as coupled to.

Through the present invention, it is possible to accurately set a photographing distance when photographing a structure, and thus it is possible to accurately determine the size of a subject in a photographed image afterwards.

In particular, the setting of the shooting distance of the present invention can be performed extremely easily by a normal smartphone 10 and a single inspector without expensive shooting and ranging equipment or the mobilization of a plurality of inspectors of 2 or more people. The convenience and efficiency of investigation can be maximized.

In addition, since most users can utilize the smartphone 10, which is familiar with how to use, without any modification, the convenience of the inspector can be increased, as well as the cost required for equipping the equipment can be drastically reduced, Even in daily inspections with minimal equipment mobilization, dimension acquisition structure photography can be performed at any time, so the quality and reliability of structure safety diagnosis or maintenance work can be improved.

The detailed configuration and use method of the present invention will be described through the accompanying drawings.

First, FIGS. 1 and 2 illustrate a state in which the present invention is mounted on a smartphone 10, and among these drawings, FIG. 1 is a state in which the present invention is mounted on a smartphone 10 and photographing a concrete wall as a test subject. is shown from the point of view of an inspector who is a user of the present invention, and FIG. 2 is shown from a reverse point of view of FIG. 1 .

As shown, the present invention is a case 20 to which the smartphone 10 is coupled, and a pair of support plates 30 protruding from the case 20 to the front of the smartphone 10 and the camera 15, that is, toward the subject. and an extension plate 40.

3 and 4 are perspective views showing the configuration of the present invention in detail, except for the smartphone 10, in the present invention, the case 20 to which the smartphone 10 is coupled is a case for a conventional smartphone 10 As in (20), the rear and side surfaces of the smartphone 10 equipped with the camera 15 are covered, but the touch screen, which is an input/output device, has a one-sided open enclosure structure.

In addition, an opening 21 is cut in the case 20, and the main camera 15 on the back of the smartphone 10 as shown in FIG. 2 in a state where the smartphone 10 is coupled to the case 20. ) is exposed to the subject side through the opening 21, and as shown in FIG. 1, the entire touch screen on the front surface of the smartphone 10 is completely exposed to the outside, enabling the user to manipulate and check the screen.

2 to 4, support plates 30, which are plates protruding toward the subject, are bonded to the surface of the case 20 on both sides of the opening 21, where the support plate 30 is orthogonal to the surface of the case 20. It does not protrude in the direction, but is bonded to have an inclination extending outward on a plane, so that a pair of support plates 30 on both sides of the opening 21 form a V shape on a plane.

The V-shaped protrusion of the support plate 30 is intended to prevent the configuration of the present invention from covering the subject or a main part in the subject in consideration of the angle of view of the camera 15, and when photographing by the camera 15, the support plate ( 30) is located outside the angle of view or at the boundary of the angle of view, so that the components of the present invention, such as the support plate 30 and the extension plate 40 to be described later, are excluded from the captured image or only partially displayed on the outer edge of the image.

That is, in the present invention, in photographing a subject, which is a subject, with a smartphone 10 in tasks such as structure safety diagnosis, the photographing distance, which is the distance between the camera 15 of the smartphone 10 and the surface of the subject, is kept constant. This is to keep the magnification of the photographed image constant by performing the photographing in the state, so that the actual size of the subject in the image can be accurately grasped even after the fact, which is to the front side of the case 20 as shown in FIG. This can be achieved by photographing in a state where the ends of both protruding extension plates 40 are brought into close contact with the surface of the subject. It is to give an enlarged structure.

In particular, the present invention does not simply protrude the long plate body or bar body forward of the smartphone 10, but the extension plate 40 protrudes forward as shown in FIGS. 1 to 3 as well as the extension plate as shown in FIG. 4 40 is rotated backward to expose the support plate 30 and can be adjusted even in a forward protruding state, the above-described shooting distance is the relative distance of the extension plate 40 protruding and the extension plate 40 is retracted and the support plate ( 30) can be set in various ways with a relatively short distance exposed.

That is, when the area required to be photographed is relatively wide, such as peeling or flaking of the surface layer or paint surface of the structure, the expansion plate 40 protrudes forward to enlarge the photographing distance, thereby reducing the photographing magnification, and reducing the relative magnification such as micro cracks or deformations. When the shooting area is narrow and detailed dimensions need to be obtained, the extension plate 40 is rotated and withdrawn as shown in FIG. It is possible to proceed with close-up photography while doing so.

The operation of the support plate 30 and the extension plate 40 of the present invention may be performed through a coupling structure as shown in FIGS. 5 and 6, and related structures are described in detail as follows.

The support plate 30, which is bonded to the surface of the case 20 on both sides of the opening 21 and protrudes toward the subject side with an outwardly enlarged inclination on a plane, is a plate body having a shorter length than the expansion plate 40 as shown in FIG. At the junction side end of the case 20 of (30), a long hole 31 is cut in a direction parallel to the center line of the support plate 30, and at the other end of the support plate 30, an annular coupling groove 33 with one side open. ) is formed.

In addition, as described above, the extension plate 40, which is a columnar plate, is coupled to the support plate 30, and the support shaft 41 is formed at the rear end of the case 20 side of the extension plate 40, and the support shaft 41 A detachable shaft 43 is formed at a position spaced apart from the center of the expansion plate 40, and the support shaft 41 is coupled to the long hole 31 so as to be freely movable.

In the illustrated embodiment, the extension plate 40 is configured by overlapping a pair of plate bodies on a plane. The pair of plate bodies are coupled to both ends of the detachable shaft 43 and the support shaft 41, respectively, and The support plate 30 is coupled between the plate bodies in a sandwich form, and the support shaft 41 penetrates the long hole 31, so that the extension plate 40 is prevented from leaving the support plate 30, and even in this coupled state, the support shaft 41 ) Free sliding in the long hole 31 is guaranteed.

In addition, as shown in FIGS. 5 and 6, the diameter of the support shaft 41 and the width of the long hole 31 match, the diameter of the detachable shaft 43 and the width of the coupling groove 33 match, and the support shaft ( 41) and the detachable shaft 43 are identical to the distance between the rear end of the long hole 31 on the case 20 side and the coupling groove 33, but the front end of the long hole 31 on the other side of the case 20 and the front end of the support plate 30 The distance between them is less than the distance between the support shaft 41 and the detachable shaft 43.

That is, in a state in which the support shaft 41 is maximally retracted in the long hole 31 and is close to the case 20, the detachable shaft 43 is captured and coupled to the coupling groove 33, but the support shaft 41 is in the long hole In a state where it moves forward as much as possible within (31) and is separated from the case 20, even if the extension plate 40 is rotated around the support shaft 41, the detachable shaft 43 is not captured by the coupling groove 33, and the detachable shaft The free rotation of the extension plate 40 is possible in a state in which (43) is spaced outward from the front end of the support plate 30.

Through this characteristic configuration of the present invention, it is possible to firmly fix the extension plate 40 in a forward protruding state and to easily release the fixed state of the extension plate 40 as shown in FIG. In a state where the shaft 41 is located at the rear end of the long hole 31 and the detachable shaft 43 is coupled to the coupling groove 33, the extension plate 40 is stably fixed to the support plate 30, the top of the same drawing As shown by a solid line in , when the extension plate 40 is slightly rotated around the support shaft 41 as an axis, the detachable shaft 43 is separated from the coupling groove 33, and then as shown by a virtual line at the bottom of the same figure. Similarly, when the extension plate 40 is rotated outward in a state in which the extension plate 40 is drawn forward and the support shaft 41 is moved forward along the long hole 31, the attachment/detachment shaft 43 of the support plate 30 While transcending the front end, the expansion plate 40 is completely rotated to the outside of the support plate 30 and the support plate 30 can be exposed.

In this way, in a state in which the tip of the extension plate 40 is in close contact with the surface of the subject and a long-range shooting distance is set, the extension plate 40 can be withdrawn and the tip of the support plate 30 is in close contact with the surface of the subject by simply taking the above-mentioned steps. , the shooting distance can also be easily adjusted from a long distance to a short distance.

In addition, it is necessary to fix the extension plate 40 in the withdrawal state to prevent unnecessary shaking of the extension plate 40 in the rotation and withdrawal state of the extension plate 40 and to enable the support plate 30 to come into close contact with the subject stably. In the present invention, the side plate 36 protruding outward is formed at the junction between the support plate 30 and the case 20, the binding shaft 37 is formed at the distal end of the side plate 36, and the support shaft of the extension plate 40 A coupling groove 47 is recessed between the 41 and the detachable shaft 43 so that the coupling groove 47 is coupled to the coupling shaft 37 in a state where the extension plate 40 is rotated to the side of the case 20. Accordingly, the expansion plate 40 is fixed, and the front end of the other side of the case 20 of the support plate 30 is stably exposed.

On the other hand, FIG. 7 is an embodiment in which one set of extension plate 40 and support plate 30 is added so that a more accurate and stable distance can be maintained in setting the shooting distance by the extension plate 40 and the support plate 30, In this case, it is advantageous for portability and ease of use to install the additional expansion plate 40 and support plate 30 on the surface of the case 20 below the camera 15 .
