Description

Target distance adjustment type scale display for structure shooting {OBJECT DISTANCE ADJUSTMENT TYPE SCALE MARKER FOR STRUCTURE PHOTOGRAPHY}

The present invention relates to an auxiliary device for photographing used in the diagnosis and inspection of various structures, in which a case 20 coupled to a smartphone 10 and a seating plate 40 in close contact with a subject are connected by a curved rod 30. , The targeting part 43 displayed on the seating plate 40 is taken together with the subject.

Photographing of a structure is a basic first step in safety diagnosis and inspection, etc., in identifying and recording various phenomena that can be confirmed externally, such as cracks, peeling, peeling, etc., as well as deformation and deterioration formed on the subject. can be put to good use.

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 in advance as well as after the fact, 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 view of the above-mentioned problems, the present invention was devised so that a shooting including a target can be easily performed as a one-person operation without attaching or detaching the subject of the target for shooting, as well as utilizing a smartphone 10 that is easy to carry and use. Thus, in the targeting display device for photographing a structure, an opening 21 is incised in the case 20 coupled to the smartphone 10, and the camera 15 of the smartphone 10 is exposed through the opening 21. , The support part 23 is bonded to the upper surface of the case 20 on one side of the opening 21, and the arc-shaped curved rod 30 is connected to the end of the support part 23, so that the support part 23 of the curved rod 30 The other end protrudes toward the front side of the camera 15 of the smartphone 10, and the end of the curved rod 30 is connected to a seating plate 40 having a front face 43 displayed, the seating plate ( 40) is laminated on the back surface of the soft contact plate 48, and the case 20 to which the smartphone 10 is coupled is placed in a state in which the soft contact plate 48 on the rear surface of the seating plate 40 is in close contact with the subject. It is a target display device for photographing a structure, characterized in that the curvature of the curved bar 30 changes according to proximity or separation.

In addition, in the present invention, a mounting plate 51, which is an L-shaped plate, is bonded to the lower end of the mounting plate 40, and a circular bubble level 50 is installed on the lower horizontal plate body of the mounting plate 51, and the mounting plate ( 51) is a target display device for photographing a structure, characterized in that an inclined reflector 53 is installed on the upper vertical plate body, and an image of the circular bubble level 50 is expressed through the inclined reflector 53.

Through the present invention, it is possible to conveniently perform a structure photographing in which actual dimensions can be obtained without an operation of attaching or detaching a target to a subject, thereby dramatically improving the convenience and speed of the structure photographing operation.

In particular, since the process of attaching and removing a target to the surface of the target structure, which is the subject, can be excluded, damage and contamination of the target that may occur during the attaching and detaching of the target can be prevented in advance, and even without an additional operator other than the photographer. As it is possible to shoot with a target only by one person, the efficiency of structure shooting work can be improved and the cost required can be reduced at the same time.

In addition, it is extremely easy to carry and operate, and most users can use the smartphone 10, which is familiar with how to use, without any modification, thereby increasing operator's convenience and reducing the cost of equipment. can be drastically reduced, and dimension acquisition structure photography can be performed at any time even during daily inspections with minimal equipment mobilization, so the quality and reliability of structure safety diagnosis or maintenance work can be improved.

First, FIGS. 1 and 2 illustrate a state in which the present invention is mounted on the smartphone 10, and as shown, the present invention includes a case 20 to which the smartphone 10 is coupled, and a table part ( 43) and a curved bar 30 connecting the case 20 and the seating 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), it has a one-sided open enclosure structure covering the rear and side surfaces of the smartphone 10, and the seating plate 40 in close contact with the subject surface is a rectangular plate body, and the surface has a protrusion 43 ) is displayed.

As shown in FIGS. 3 and 4, the case 20 has an opening 21 cut, and the case 20 has the smartphone 10 coupled to the case 20, as shown in FIG. 2, the rear surface of the smartphone 10 The main camera 15 is exposed through the opening 21, and as shown in FIG. 1, the entire touch screen on the front side of the smartphone 10 is completely exposed to the outside, so that the user's operation and screen confirmation are possible. It becomes possible.

As shown in FIGS. 2 and 4 , a support part 23 is bonded to the upper surface of the case 20 on one side of the opening 21, and an arc-shaped curved rod 30 is connected to the end of the support part 23. The other end of the support portion 23 of (30) protrudes toward the front side of the camera 15 of the smartphone 10, where the support portion 23 is configured in the form of a pipe to which the curved rod 30, which is a small diameter rod, can be coupled. The other end of the coupling part of the curved bar 30 of the support part 23 is firmly fixed to the case 20.

In addition, as shown in FIGS. 1 to 4, an upward curve is formed in the support 23 to which the curved rod 30 is coupled and connected, so that when the curved rod 30 is coupled, the support 23 of the curved rod 30 ) Give a gentle upward slope to the end of the coupling side.

In the present invention, the curved rod 30 is a small-diameter, long-barreled rod with a diameter of 5 mm or less made of metal or synthetic resin, and has appropriate strength and elasticity. ) And it is gently curved by the weight of the bending rod 30 to form an arc shape as a whole, and the other end of the support part 23 of the bending rod 30 has the front part 43 displayed. The seating plate 40 is connected through a hinge 41, and the connection portion is located above the seating plate 40, so that the seating plate 40 in a free state has a vertical or near-vertical posture.

Therefore, as shown in FIG. 5, when the smartphone 10 equipped with the present invention is gradually brought closer to the subject, the rear surface of the seating plate 40 is in close contact with the subject, and the elasticity of the curved bar 30 and the seating plate ( 40) The mounting plate 40 on which the leveling part 43 is displayed can be temporarily fixed to the subject without a separate adhesive or fixing means by the frictional force between the rear surface and the surface of the subject. In this way, the mounting plate 40 is temporarily fixed. When taking a picture with the smartphone 10 in , as shown in the excerpted enlarged part of the same figure, it is possible to obtain a picture in which the profiling part 43 is accompanied at the upper part.

As shown in FIGS. 2 and 4, a soft adhesion plate 48 is laminated on the back surface of the seating plate 40 to promote close adhesion between the seating plate 40 and the subject, and at the same time increase frictional force to seat the hard plate body. The plate 40 suppresses the sliding phenomenon on the surface of the subject. The soft contact plate 48 is a soft contact plate as in the dictionary meaning, and an elastic material such as rubber or sponge is applied.

In the accompanying drawings, including FIG. 5, the curved bar 30 and the mounting plate 40 are used in a state in which they have postures close to horizontal and vertical, respectively, which assumes a situation where the subject is mainly a vertical surface such as a wall or pillar The invention can be said to be used on the premise of taking pictures of vertical or near-vertical slopes where it is difficult to temporarily mount a scale.

That is, if the subject has a horizontal or near-horizontal surface, the position of the target can be maintained even if the target is simply mounted, but in the case of a vertical or near-vertical inclined surface, it is impossible to simply mount the target, utilizing the present invention As shown in FIG. 5, as shown in FIG. 5, the smartphone 10 can be freely operated while the mounting plate 40 on which the pointing part 43 is displayed is temporarily fixed to the subject. Rather, a single inspector can perform all of these tasks alone.

In particular, as shown in FIG. 6, when the case 20 to which the smartphone 10 is coupled is brought closer to or separated from the subject in a state in which the soft contact plate 48 on the rear surface of the seating plate 40 is in close contact with the subject, As the curvature of the curved rod 30 changes, the shooting distance between the subject and the mounting plate 40 and the smartphone 10 and the camera 15 can be freely adjusted. (40) can be stably maintained in its position.

In this way, by performing photographing in a state in which the seating plate 40 configured with the leveling part 43 is seated on the surface of the subject, it is possible to take a photograph of the subject as in the enlarged excerpt of FIG. Through the included targeting unit 43, it is possible to accurately grasp the actual dimensions of the subject, such as the cracked portion of the illustrated embodiment.

In addition, as in the illustrated embodiment, a blank space may be formed on the front portion of the seating plate 40 in addition to the targeting portion 43 to write the name of the shooting site or a date in the blank space.

On the other hand, Figure 7 is an embodiment of the present invention to which a level is applied, through which not only the actual size of the subject but also the fine angle of inclination of the subject surface can be checked and photographed.

That is, as shown in the enlarged excerpt from the left of FIG. 7, a mounting plate 51, which is an L-shaped plate body, is bonded to the lower end of the mounting plate 40, and a circular bubble level 50 is attached to the upper surface of the lower horizontal plate body of the mounting plate 51. ) is installed, and an inclined reflector 53 is installed on the upper vertical plate body of the mounting plate 51, and when the subject is photographed by the smartphone 10 camera 15, as shown in the enlarged portion excerpted from the right of FIG. It is so that the image of the bubble level 50 can be expressed through the inclined reflector 53.

Conventional levels, including the circular bubble level 50, are mainly manufactured so that the user can observe the bubble on the upper part of the level while mounted on a horizontal or near-horizontal inclined surface, and simply mount the level on a vertical or near-vertical surface. In the case of attaching and photographing, the level itself may be photographed, but the bubble position, which is the result of measuring the level, cannot be photographed.

Therefore, in the present invention, by installing the inclined reflector 53 inclined forward on the camera 15 side on the upper side of the circular bubble level 50, the image of the upper part of the circular bubble level 50 is on the inclined reflector 53. By doing so, the position of the bubble in the circular bubble level 50 can be accurately photographed, so that not only the size of the subject but also the inclination angle can be grasped through photographing.
