Description

The present invention relates to a photographing device for photographing the surface of an object such as a wall surface of a structure, and a photographing jig.

Structures such as tunnels and bridges require regular inspections to check for damage. Such inspections are carried out, for example, by taking images of the walls of structures, such as taking pictures of the inside of a tunnel while driving a vehicle equipped with a large camera, or attaching a camera to an arm to under the girder of a bridge. I was shooting.

Patent Document 1 includes a guide rail installed in a tunnel along a road and a mobile TV camera that moves on the guide rail, and serves as a civil engineering structure based on image information from the mobile TV camera. A road tunnel comprehensive monitoring and control device that manages tunnels and roads is described.

Japanese Unexamined Patent Publication No. 11-44200

However, in the technique described in Patent Document 1, it is necessary to permanently install a guide rail in the tunnel which is the object to be inspected, and to install a mobile TV camera moving on the guide rail on the guide rail. For this reason, the cost for installing these facilities becomes high, and the work becomes large.

When the inside of the cave is the object to be inspected, the cable is laid near the wall surface in the cave, and the space between the cable and the wall surface is very narrow. Therefore, even if you try to take a picture of the wall surface in the cave, the cable becomes an obstacle and it becomes difficult to take a picture.

Even if you can take a picture of the wall surface in the cave, if you do not take a picture at a certain distance and a certain angle with respect to the wall surface, when comparing the image of the taken wall surface with the surrounding image to check for damage etc. , The reliability of the inspection becomes low. It should be noted that the large-scale equipment as described in Patent Document 1 cannot be used in the narrow space between the cable and the wall surface, and the wall surface cannot be photographed.

In view of such a problem, an object of the present invention is to provide a photographing device and a photographing jig that can reliably photograph the surface of an object such as a wall surface of a structure even in a place where only a narrow space can be secured. There is.

In order to solve the above problems, a typical configuration of the photographing device according to the present invention is a photographing device for photographing an image of the surface of an object, and the camera, a trolley supporting the camera, and traveling on the trolley. A rail to be provided, a leg having a predetermined length extending from the vicinity of both ends of the rail, and a foot provided at the tip of the leg to fix the leg at a predetermined angle to the surface of an object. It is a feature.

In the above configuration, the rail on which the dolly supporting the camera travels has a certain distance from the surface of the object to be photographed (inspection object) by the legs having a predetermined length extending from the vicinity of both ends thereof. The rail is further angled to the surface of the object by the foot, which secures the legs to the surface of the object at a predetermined angle. That is, the rail is maintained at a constant distance and at a constant angle with respect to the surface of the object. Therefore, a camera supported by a dolly traveling on a rail can photograph the surface of an object at a constant distance and a constant angle.

As an example, a case where a cable is laid near the wall surface and the inside of a cave where only a narrow space can be secured between the wall surface and the cable is set as an inspection target will be described. In such a case, the operator advances the legs near both ends of the rail and the feet provided at the tips of the legs toward the wall surface so as to avoid the cable, and further presses the feet against the wall surface. In this way, the rail can be maintained at a constant distance and a constant angle from the wall surface. Then, by running the dolly on the rail, the camera can take a picture of the wall surface in the cave at a certain distance and a certain angle. Therefore, according to the photographing apparatus having the above configuration, the surface of an object such as a wall surface of a structure can be reliably photographed even in a place where only a narrow space can be secured.

Moreover, since the structure is simple and small, no large-scale equipment is required and the cost is low. Since it can be made even lighter, it is also excellent in portability and handling during shooting.

The above camera should be supported by a dolly together with the light and run on the rail. In this way, since the camera is driven together with the light that is the light source, the surface of the object can be photographed even in a dark place with the minimum light source.

In order to solve the above problems, a typical configuration of the photographing jig according to the present invention is a photographing jig for photographing an image of the surface of an object, which is a rail for traveling a camera and a rail. It is characterized by including a leg portion having a predetermined length extending from the vicinity of both ends and a foot portion provided at the tip of the leg portion and fixing the leg portion at a predetermined angle with respect to the surface of an object.

The components corresponding to the above-mentioned technical idea in the photographing apparatus and the description thereof can also be applied to the photographing jig. That is, according to the shooting jig having the above configuration, the rail can be maintained at a constant distance and a constant angle with respect to the surface of the object even in a place where only a narrow space can be secured, so that the camera can be driven on the rail. By doing so, the surface of the object can be photographed at a constant distance and a constant angle.

It is preferable that the foot portion is a long member that comes into contact with the surface of the object, extends from the leg portion in both directions or only in one direction, and forms a right angle to the rail. In this way, the foot is a long member that forms a right angle to the rail and extends from the leg in both directions or only in one direction, so it is easy to enter a place where only a narrow space can be secured. Further, it can be brought into contact with the surface of an object.

The above-mentioned foot is a member that comes into contact with the surface of an object, and one side of the leg is rotatable so as to fold, and the other side is restricted from rotation smaller than a right angle. good. As a result, by folding the foot on one side of the leg, it is easy to enter a place where only a narrow space can be secured. In addition, after the foot is made to enter a narrow space, the foot is brought into contact with the surface of the object by abutting the tip of the foot against the surface of the object (wall surface, etc.) and raising (rotating) the foot to further the object. The legs can be fixed at right angles to the surface.

The foot portion is a metal fitting provided with a bolt hole, and may be fixed to an existing structure with bolts to fix the leg portion at a predetermined angle. As a result, the rail can be reliably maintained at a constant distance and a constant angle with respect to the surface of the object simply by fixing the foot and the existing structure with bolts.

The foot portion may be a clip type, and the leg portion may be fixed at a predetermined angle by sandwiching the existing structure. In this way, the legs can be fixed at a predetermined angle by a simple operation of sandwiching the existing structure with the clip-type feet. In addition, since the foot is a clip type, it is easy to put on and take off, and workability can be improved.

According to the present invention, it is possible to provide a photographing jig capable of reliably photographing the surface of an object such as a wall surface of a structure even in a place where only a narrow space can be secured.

The "surface of an object", which is an object to be inspected in the present embodiment, will be described by using the wall surface of a cable tunnel as an example. However, the present invention is not limited to this, and the surface of various objects can be an object to be inspected. The most typical example is the wall surface of a structure, but it can also be applied to the floor surface and ceiling of a structure, the surface of a structure such as a bridge, and the like. Further, it can be suitably applied not only to artificial structures but also to the surfaces of natural objects such as the ground and strata.

(First Embodiment)
FIG. 1 is a diagram showing a state in which a wall surface 104 in a cable tunnel 102 is photographed by using the photographing apparatus 100 according to the first embodiment of the present invention. FIG. 2 is a diagram showing a photographing device 100.

The cable tunnel 102 is a structure excavated by, for example, a shield method, and its wall surface 104 is reinforced with a plate called a segment. Since the segment is a concrete block, it may crack due to aging. Therefore, in the cable tunnel 102, periodic inspection is required to confirm whether or not the wall surface 104 is damaged.

The inspection of the cable tunnel 102 is carried out by photographing the wall surface 104. As an example, a plurality of images of the photographed wall surface 104 are combined, and the photographed image is mapped to a map of a cable tunnel to confirm the presence or absence of damage.

In the cable tunnel 102, a plurality of cables 106 such as power cables and communication cables are accommodated and laid near the wall surface 104. A vertical metal fitting 108 extending in the vertical direction is installed near the wall surface 104. An arm 110 is attached to the vertical hardware 108. The arm 110s are provided in a plurality of stages separated from each other in the vertical direction, and extend horizontally so as to be away from the wall surface 104. The cable 106 is installed on the arm 110 attached to the vertical hardware 108, and is laid along the vicinity of the wall surface 104 in the cable tunnel 102 as shown in the figure.

Therefore, in the cable tunnel 102, there is a place 112 where only a narrow space can be secured between the cable 106 and the wall surface 104. Therefore, even if the worker 114 tries to photograph the wall surface 104 in order to inspect the wall surface 104, the cable 106 becomes an obstacle and the photographing becomes difficult.

Even if the wall surface 104 in the cable tunnel 102 can be photographed, if the wall surface 104 is not photographed at a constant distance and at a constant angle, when comparing the images of the wall surface 104 to confirm the presence or absence of damage, etc. The reliability of the inspection will be low. Moreover, in the place 112 where only a narrow space can be secured, large-scale equipment cannot be used, and the wall surface 104 cannot be photographed.

Therefore, in the present embodiment, by using the photographing device 100, even in the place 112 where only a narrow space can be secured, the distance is constant with respect to the wall surface 104 in the cable tunnel 102 which is the object to be photographed (the object to be inspected). The wall surface 104 can be reliably photographed at a constant angle.

The photographing device 100 is a device for photographing the surface of an object such as the wall surface of a structure (here, the wall surface 104 in the tunnel 102). The photographing apparatus 100 includes a photographing jig 101 as shown in FIG. The photographing jig 101 includes a rail 118 for traveling the camera 116, a pair of legs 120 and 122, and a pair of feet 124 and 126. The pair of legs 120, 122 extend in a predetermined direction (here, as an example, the shooting direction of the camera 116) from the vicinity of both ends 128, 130 of the rail 118, and have a predetermined length.

The pair of foot portions 124, 126 are provided at the tips 132, 134 of the pair of leg portions 120, 122, and the leg portions 120, 122 are provided at a predetermined angle (here, a right angle) with respect to the wall surface 104 in the tunnel 102. Fix it. Specifically, the pair of foot portions 124 and 126 extend in a direction orthogonal to any longitudinal direction of the rail 118 and the pair of leg portions 120 and 122, and further bidirectionally (both directions) from the pair of leg portions 120 and 122. It extends to form a T-shape.

Here, in order to securely fix the legs 120 and 122 to the wall surface 104 at a predetermined angle, it is necessary to form a plane (quadrilateral) including the pair of foot portions 124 and 126 as two sides. Therefore, if this plane can be formed, the longitudinal direction of the pair of foot portions 124 and 126 does not necessarily have to be orthogonal to the longitudinal direction of the rail 118.

However, if the longitudinal direction of the pair of foot portions 124 and 126 becomes parallel to the longitudinal direction of the rail 118, a flat surface cannot be formed and the leg portions 120 and 122 cannot be stably fixed to the wall surface 104. Therefore, the pair of foot portions 124 and 126 are set to extend in a direction that is not parallel to the longitudinal direction of the rail 118.

The photographing apparatus 100 further includes a camera 116 and a trolley 136 in addition to the photographing jig 101. The camera 116 is mounted on a dolly 136 capable of traveling on the rail 118. The dolly 136 is further equipped with lights 138 and 140 near both sides of the camera 116. Therefore, the camera 116 can travel on the rail 118 together with the lights 138 and 140, which are light sources, and can photograph the wall surface 104 in the cable tunnel 102 even in a dark place with the minimum light source.

Here, the distance and angle of the rail 118 with respect to the wall surface 104 in the cable tunnel 102, which is the object to be photographed, will be described. The rail 118 has a certain distance from the wall surface 104 in the cable tunnel 102 by the legs 120 and 122 having a predetermined length extending from the vicinity of both ends 128 and 130 in the shooting direction of the camera 116.

The rail 118 is further set at a constant angle with respect to the wall surface 104 in the cable tunnel 102 by the foot portions 124 and 126 that fix the legs 120 and 122 to the wall surface 104 in the cable tunnel 102 at a predetermined angle. Therefore, the rail 118 is maintained at a constant distance and at a constant angle with respect to the wall surface 104 in the cable tunnel 102.

Hereinafter, a procedure for photographing the wall surface 104 in the cable tunnel 102 will be described using the photographing apparatus 100 shown in FIG. First, the operator 114 (see FIG. 1) causes the legs 120, 122 and the feet 124, 126 to enter toward the wall surface 104 so as to avoid the cable 106, and further presses the feet 124, 126 against the wall surface 104. ..

By doing so, the rail 118 is maintained at a constant distance and a constant angle from the wall surface 104 even in the place 112 where only a narrow space can be secured between the cable 106 and the wall surface 104. Next, the worker 114 photographs the wall surface 104 in the cable tunnel 102 at a constant distance and at a constant angle by running the camera 116 on the rail 118.

The images of the wall surface 104 taken are continuously taken by the traveling camera 116 at a certain distance and at a certain angle. Therefore, it is possible to perform a highly reliable inspection when synthesizing a plurality of captured images and confirming the presence or absence of damage to the wall surface 104.

As described above, the photographing apparatus 100 according to the first embodiment has a constant distance and a constant angle in the cable tunnel 102 by the camera 116 traveling on the rail 118 even in the place 112 where only a narrow space can be secured. The wall surface 104 can be reliably photographed.

Further, since the photographing device 100 has a simple structure and is small in size, it does not require large-scale equipment and is inexpensive. Further, since the photographing device 100 can be made lightweight, it is also excellent in carrying and handling at the time of photographing.

(Second Embodiment)
FIG. 3 is a diagram showing a photographing device 100A according to the second embodiment of the present invention. It should be noted that the figure shows a state in which the photographing device 100A is viewed from the side, and further shows a procedure for photographing the wall surface 104 in the cable tunnel 102 using the photographing device 100A.

The photographing apparatus 100A is different from the above-mentioned photographing apparatus 100 in that the photographing jig 101A includes the leg portion 120A and the foot portion 124A forming an L shape. The foot portion 124A is a long member that comes into contact with the wall surface 104 in the tunnel 102. Further, the foot portion 124A is attached to the tip 132A of the leg portion 120A, extends from the leg portion 120A in only one direction, forms a right angle to the longitudinal direction of the rail 118 (see FIG. 2), and forms an L-shape. are doing.

When the wall surface 104 in the cable tunnel 102 is photographed by using such an imaging device 100A, the operator 114 first shows the foot portion 124A forming an L-shape together with the leg portion 120A as shown in FIG. 3A. (See arrow A) while rotating the cable 106 so as to avoid it and approaching the wall surface 104. Next, as shown in FIG. 3B, the operator 114 slightly rotates the photographing device 100A toward the foot portion 124A and presses the foot portion 124A against the wall surface 104 (see arrow B).

By doing so, the rail 118 can be maintained at a constant distance and a constant angle from the wall surface 104 as shown in FIG. 3B even in the place 112 where only a narrow space can be secured. Then, the worker 114 takes a picture of the wall surface 104 in the cable tunnel 102 at a certain distance and a certain angle by running the camera 116 on the rail 118.

Therefore, even in the place 112 where only a narrow space can be secured by the photographing device 100A, the wall surface 104 in the tunnel 102 can be reliably photographed at a constant distance and a constant angle. In particular, since the foot portion 124A forms a right angle to the rail 118 and extends from the leg portion 120A in only one direction, it is easy to enter the place 112 where only a narrow space can be secured, and the foot portion 124A is further brought into contact with the wall surface 104. Can be done.

(Third Embodiment)
FIG. 4 is a diagram showing a photographing device 100B according to a third embodiment of the present invention. It should be noted that the figure shows a state in which the photographing device 100B is viewed from the side, and further shows a procedure for photographing the wall surface 104 in the cable tunnel 102 using the photographing device 100B.

The photographing device 100B is different from the above-mentioned photographing devices 100 and 100A in that the photographing jig 101B is provided with a movable foot portion 124B with respect to the leg portion 120B. The foot portion 124B is a long member that comes into contact with the wall surface 104 in the cable tunnel 102, and is rotatably attached to the tip 132B of the leg portion 120B. However, the shape of the foot portion 124B is not limited to this as long as it can abut on the wall surface 104, and may be, for example, a circular shape (see FIG. 5).

More specifically, the foot portion 124B is rotated clockwise as shown in FIG. 4A in the clockwise direction (one side) in which one end 142 thereof approaches the leg portion 120B from below the leg portion 120B. It is movable.

Further, the foot portion 124B is provided with a rotation restricting portion 146 provided on the upper side of the tip 132B of the leg portion 120B in the counterclockwise direction (on the other side) in which the other end 144 approaches the leg portion 120B from above the leg portion 120B. , Rotation smaller than a right angle is restricted.

When the wall surface 104 in the cable tunnel 102 is photographed by using such an imaging device 100B, the worker 114 first sets the foot portion 124B in a folded state with respect to the leg portion 120B, and sets the foot portion 124B in this state. As shown in FIG. 4A, the cable 106 is avoided and entered toward the wall surface 104 (see arrow C).

Next, the operator 114 abuts the other end 144 of the folded foot portion 124B against the wall surface 104 and rotates the foot portion 124B, and then lightly presses the foot portion 124B so that the foot portion 124B is solidified at a right angle as shown in FIG. 4 (b). See arrow D). As a result, the leg 120B of the photographing apparatus 100B is fixed at a right angle to the wall surface 104.

By doing so, the rail 118 can be maintained at a constant distance and a constant angle from the wall surface 104 as shown in FIG. 4B even in the place 112 where only a narrow space can be secured. Then, the worker 114 takes a picture of the wall surface 104 in the cable tunnel 102 at a certain distance and a certain angle by running the camera 116 on the rail 118.

Therefore, even in the place 112 where only a narrow space can be secured by the photographing device 100B, the wall surface 104 in the tunnel 102 can be reliably photographed at a constant distance and a constant angle. In particular, the foot portion 124B can be rotated so as to be folded on one side of the leg portion 120B, and rotation smaller than a right angle is restricted on the other side, so that even in a place 112 where only a narrow space can be secured. Easy to enter.

(Fourth Embodiment)
FIG. 5 is a diagram showing a photographing apparatus 100C according to the fourth embodiment of the present invention. FIG. 5A is a perspective view showing the entire photographing apparatus 100C. FIG. 5B is an enlarged view showing a part of the photographing apparatus 100C shown in FIG. 5A.

The photographing device 100C is different from the above-mentioned photographing devices 100, 100A and 100B in that the photographing jig 101C includes the leg portions 124C and 126C which are movable with respect to the legs 120C and 122C. The feet 124C and 126C are members that come into contact with the wall surface 104 in the cable tunnel 102, and are rotatably attached to the tips 132C and 134C of the legs 120C and 122C as shown in FIG. 5A. There is.

More specifically, the disc-shaped foot portion 124C is folded as shown in FIG. 5B in the direction (one side) in which the upper edge 143 approaches the leg portion 120C from above the leg portion 120C. (See arrow E).

Further, the foot portion 124C is smaller than a right angle by the rotation restricting portion 147 provided at the tip 132C of the leg portion 120C in the direction (the other side) in which the lower edge 145 approaches the leg portion 120C from below the leg portion 120C. Rotation is restricted. As shown in FIG. 5B, the rotation control unit 147 is notched upward so as to allow rotation of the tip 132C to one side. Similarly, the foot portion 126C shown in FIG. 5A is rotatable so as to be folded on one side of the leg portion 122C, and rotation smaller than a right angle is restricted on the other side.

Therefore, in the photographing jig 101C, the vertical dimension can be reduced by folding the disc-shaped feet 124C and 126C to one side of the legs 122C. Therefore, when the wall surface 104 in the cable tunnel 102 shown in FIG. 1 is photographed by using the photographing apparatus 100C, the worker 114 first sets the legs 124C and 126C in a folded state with respect to the legs 120C and 122C, and in this state. The feet 124C and 126C of the above are made to enter toward the wall surface 104 while avoiding the cable 106.

Next, the worker 114 abuts the lower edges 145 of the folded feet 124C and 126C against the wall surface 104 and rotates them, and lightly presses the feet 124C and 126C so that they are solidified at a right angle. As a result, the legs 120C and 122C of the photographing apparatus 100C are fixed at right angles to the wall surface 104.

By doing so, the rail 118 can be maintained at a constant distance and a constant angle from the wall surface 104 even in a place 112 where only a narrow space can be secured. Then, the worker 114 takes a picture of the wall surface 104 in the cable tunnel 102 at a certain distance and a certain angle by running the camera 116 on the rail 118.

Therefore, even in the place 112 where only a narrow space can be secured by the photographing device 100C, the wall surface 104 in the tunnel 102 can be reliably photographed at a constant distance and a constant angle. In particular, the feet 124C and 126C can be rotated so as to be folded on one side of the legs 120C and 122C, and rotation smaller than a right angle is restricted on the other side, so that only a narrow space can be secured. It is easy to enter the place 112.

(Fifth Embodiment)
FIG. 6 is a diagram showing a state in which the wall surface 104 in the cable tunnel 102 is photographed by using the photographing apparatus 100D according to the fifth embodiment of the present invention. The photographing device 100D is different from the above-mentioned photographing devices 100 and 100A to 100C in that the photographing jig 101D is fixed to the vertical hardware 108 and 148 with bolts 150. The vertical hardware 108 and 148 are existing structures installed at regular intervals in the cave 102.

The photographing jig 101D includes a rail 118 for traveling the camera 116, a pair of legs 152, 154, and a pair of feet 156, 158. As shown in the figure, the pair of legs 152 and 154 are directed in a predetermined direction from the vicinity of both ends 128 and 130 of the rail 118 (here, as an example, in the direction opposite to the shooting direction of the camera 116, that is, toward the vertical hardware 108 and 148. It extends in the direction) and has a predetermined length.

The pair of foot portions 156 and 158 are metal fittings provided with bolt holes, and are fixed to the vertical metal fittings 108 and 148 with bolts 150 as shown in the figure, so that the legs are attached to the wall surface 104 in the tunnel 102. The portions 152 and 154 are fixed at a predetermined angle (here, a right angle).

In this way, in the photographing jig 101D, the rail 118 is fixed at a constant distance and constant with respect to the wall surface 104 in the cable tunnel 102 by simply fixing the feet 156 and 158 to the vertical hardware 108 and 148 with bolts 150. Can be reliably maintained at an angle. Therefore, even in the place 112 where only a narrow space can be secured by the photographing device 100D, the wall surface 104 in the tunnel 102 can be reliably photographed at a constant distance and a constant angle.

The pair of foot portions 156 and 158 are fixed to the vertical metal fittings 108 and 148 with bolts 150, but instead, they are fixed to the edge metal fittings 160 and 162 installed along the wall surface 104 with bolts 150. May be good. The edge hardware 160 and 162 are existing structures installed at regular intervals in the cave 102, and are located at positions facing, for example, the vertical hardware 108 and 148.

Even in such a case, the legs 152 and 154 can be fixed at a predetermined angle by simply fixing the feet 156 and 158 to the existing structure, that is, the rims 160 and 162 with bolts 150, and the rail 118 can be fixed. It can be reliably maintained at a constant distance and a constant angle with respect to the wall surface 104. Therefore, even in the place 112 where only a narrow space can be secured, the wall surface 104 in the cable tunnel 102 can be reliably photographed at a constant distance and a constant angle.

(Sixth Embodiment)
FIG. 7 is a diagram showing a state in which the wall surface 104 in the cable tunnel 102 is photographed by using the photographing apparatus 100E according to the sixth embodiment of the present invention. The photographing apparatus 100E is different from the above-mentioned photographing apparatus 100, 100A to 100D in that the photographing jig 101E is clipped to the edge metal objects 160, 162 which are existing structures.

Specifically, the photographing jig 101E includes a rail 118 for traveling the camera 116, a pair of legs 164 and 166, and a pair of feet 168 and 170. As shown in the figure, the pair of legs 164 and 166 extend from the vicinity of both ends 128 and 130 of the rail 118 toward the shooting direction of the camera 116 and have a predetermined length.

The pair of foot portions 168 and 170 are clip-type and are connected by a pan head 172 and 174 installed at the tips of the pair of leg portions 164 and 166, and the angle can be adjusted. That is, the pair of foot portions 168 and 170 sandwich the edge metal fittings 160 and 162, which are existing structures, and fix the leg portions 164 and 166 at a predetermined angle.

As described above, in the photographing jig 101E, the legs 164 and 166 can be fixed at a predetermined angle by a simple operation of sandwiching the metal edges 160 and 162 by the clip-type feet 168 and 170.

Therefore, even in a place 112 where only a narrow space can be secured by the photographing device 100E, the rail 118 is surely maintained at a constant distance and a constant angle with respect to the wall surface 104 in the cable tunnel 102, and at a constant distance. The wall surface 104 in the cable tunnel 102 can be reliably photographed at a certain angle. In particular, since the feet 168 and 170 are clip-type, they can be easily attached and detached, and workability can be improved.

The pair of foot portions 168 and 170 are clipped to the edge metal fittings 160 and 162, but instead of this, they may be clipped to the vertical metal fittings 108 and 148 (see FIG. 6).

Even in such a case, the legs 164 and 166 can be fixed at a predetermined angle by simply clipping the feet 168 and 170 to the existing structure, that is, the vertical hardware 108 and 148, and the rail 118 can be attached to the wall surface 104. Can be reliably maintained at a constant distance and at a constant angle. Therefore, even in the place 112 where only a narrow space can be secured, the wall surface 104 in the cable tunnel 102 can be reliably photographed at a constant distance and a constant angle.

(7th Embodiment)
FIG. 8 is a diagram showing a state in which the wall surface 104 in the cable tunnel 102 is photographed by using the photographing apparatus 100F according to the seventh embodiment of the present invention. It should be noted that the figure shows a state in which the photographing jig device 100F is viewed from the side.

As shown in the figure, the above-mentioned vertical hardware 108, 148 and edge hardware 160, 162 are not installed in the cave 102. Therefore, it is possible to adopt a configuration in which anchor bolts 176 are embedded in the wall surface 104 and plate-shaped mounting brackets 178 are installed in segment units with anchor bolts 176. The anchor bolt 176 and the mounting bracket 178 may be constantly installed on the wall surface 104 or may be removable.

The photographing jig 101F includes a rail 118 for traveling a camera (not shown), a leg 180, and a foot 182 provided at the tip of the leg 180. The leg 180 extends from the rail 118 toward the shooting direction of the camera and has a predetermined length. The foot portion 182 is a clip type, and holds a plate-shaped mounting bracket 178 to fix the leg portion 180 to the wall surface 104 at a predetermined angle (here, a right angle). However, the fixing method is not limited to this as long as the leg 180 can be fixed to the wall surface 104 at a predetermined angle. An appropriate fixing method may be used, such as fixing to the attached mounting bracket 178 with bolts.

As described above, in the photographing jig 101F, the rail 118 is attached to the wall surface 104 in the cable tunnel 102 even when the vertical hardware 108, 148 and the edge hardware 160, 162 are not installed in the cable tunnel 102. It can be reliably maintained at a constant distance and a constant angle. Therefore, according to the photographing device 100F, the wall surface 104 in the tunnel 102 can be reliably photographed at a constant distance and a constant angle. In particular, since the foot portion 182 is a clip type, it is easy to put on and take off, and workability can be improved.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the claims, which naturally belong to the technical scope of the present invention. Understood.

INDUSTRIAL APPLICABILITY The present invention can be used as a photographing device and a photographing jig for photographing the surface of an object such as a wall surface of a structure.
