Description

The present invention relates to a camera mounting jig and a camera device. More specifically, the present invention relates to a camera mounting jig and a camera device that can prevent an unnecessary object from being reflected in an image captured by a camera and can clearly capture a required image.

2. Description of the Related Art In recent years, data can be easily transmitted due to the spread of the Internet. Therefore, for example, a monitor camera installed at a specific place in a remote place and a network-type monitor camera system using the Internet have become popular. These network-type surveillance camera systems are widely used in various places, such as providing information for natural disasters, grasping the progress of work at civil engineering and construction sites, and monitoring suspicious persons in factories and stores. It is used (Patent Document 1).

When such a surveillance camera is installed by embedding it in a ceiling or a wall, a mounting jig as disclosed in Patent Document 2, for example, is used. Specifically, as shown in FIG. 6, an upper frame 501 and a lower frame 502 that are substantially parallel to and spaced apart from the mounting surface of the building are provided, and the upper frame 501 and the lower frame 502 are connected by a connecting member 503. Has been done. The surveillance camera is attached to an attachment member 504 arranged between the upper frame 501 and the lower frame 502. The mounting member 504 can be raised and lowered by the elevating means 505 between the upper frame 501 and the lower frame 502, and is fixed at a predetermined height position.

When installing a surveillance camera outdoors, such as in a river without a ceiling or wall, a tripod (or monopod) 601 is erected at a specific position to be monitored as shown in FIG. A method of firmly fixing the camera 602 at a predetermined height position of 601 is used.

Such a monitoring camera is fixed at a specific position to be monitored and is used to constantly monitor the specific position. On the other hand, in a wide area such as a river or factory, even if an omnidirectional camera that can control pan, tilt, and zoom is used, the target range that can be monitored by one camera is limited. Therefore, it is impossible to monitor every corner of the monitoring target area. Therefore, a monitoring system has been proposed in which a plurality of cameras are installed at regular intervals and each camera captures an image of a tracking target (Patent Document 3).

However, the technique disclosed in Patent Document 3 has a problem that the installation cost of the cameras increases because it is necessary to install a plurality of cameras. Furthermore, the system configuration for linking the cameras becomes complicated, and when a system failure occurs, the linking system is interrupted and it is impossible to track the monitoring target.

To address the above issues, for example, one omnidirectional camera was attached to a patrol vehicle that patrols a river or factory, and the patrol vehicle patrols the site to be monitored, and at the same time, it is attached to the patrol vehicle. It is possible to take a picture of the surroundings with a camera. Then, a dedicated mounting jig is required for mounting the camera on such a patrol vehicle. For example, in Patent Document 4 and Patent Document 5, a mounting jig for mounting the camera on a vehicle as a moving body is used. An ingredient is disclosed.

For example, in the mounting jig disclosed in Patent Document 4, the lower end of the pillar member 701 is mounted on the rear side of the electric cart serving as the vehicle 704 and is higher than the lower end of the pillar member 701, as shown in FIG. 8A. The upper end of the pillar member 701 is located at the position, and a mounting base 702 for mounting the camera 703 is fixed to this upper end. Therefore, according to Patent Document 4, since the camera 703 and the vehicle 704 are separated by the height of the pillar member 701, it is possible to prevent the vehicle 704 and the mount 702 of the camera 703 from being reflected in the image captured by the camera 703. This makes it possible to take clear images in all directions.

Further, as shown in FIG. 8B, in the mounting jig disclosed in Patent Document 5, a slidable mount 801 is mounted on a carrier 803 on a roof surface 805 of a vehicle 804, and a mount 801 mounts a pedestal 802 on the mount 801. The camera 806 is attached to the camera. According to Patent Document 5, as in Patent Document 4, it is possible to prevent the vehicle 804 and the pedestal 802 from being reflected in the image captured by the camera 806, and it is possible to capture a clear image in all directions. Is becoming

JP-A-2009-105799 JP, 2005-65642, A JP, 2003-324720, A JP-A-2002-62579 JP, 2016-223862, A

By the way, the mounting jigs described in Patent Documents 4 and 5 are, for example, hemispherical and light-transmissive dome covers for protecting the camera main body including the lens are in a direction opposite to the installation surface. It is premised that it is installed so that it faces the upper side (empty side). In this way, if the camera is installed so that the transparent dome cover faces upward, as described above, it is possible to prevent the reflection of the vehicle and the mounting jig, but in bad weather etc. You will be exposed to wind and rain.

Mud and dust contained in rainwater and the like adhere to the dome cover directly exposed to wind and rain for a long time, and cause cracks and the like on the surface of the dome cover. The mud, dust, or cracks attached to the dome cover are naturally reflected in the image captured by the camera, and there is a possibility that a clear image cannot be captured.

Therefore, the operator needs to regularly clean the dome cover and check for cracks, but the work burden is very heavy. On the other hand, in order to prevent the dome cover from being directly exposed to weather and the like, it is necessary to attach the camera to the roof surface or the like of the vehicle so that the dome cover faces downward (ground side). However, in order to make the dome cover face downward with respect to the roof surface of a vehicle without a ceiling surface, a mounting jig for suspending the camera from above is required. Since the mounting jig inevitably has an intersecting portion, there is a problem that a part of the mounting jig is necessarily reflected in the image taken by the camera.

The present invention was devised in view of the above points, and a camera mounting fixture that can prevent an unnecessary object from being reflected in an image captured by a camera and can clearly capture a required image. An object of the present invention is to provide a tool and a camera device.

Hereinafter, an embodiment of the present invention relating to a camera mounting jig and a camera device will be described with reference to the drawings to provide an understanding of the present invention. In each drawing, when the camera mounting jig 3 is installed on the installation surface, the upward direction from the installation surface is defined as an upward direction, and the opposite direction to the upward direction is defined as a downward direction for convenience of description. , An upward direction and an downward direction are defined as a vertical direction, and an axial direction perpendicular to the vertical direction is defined as a horizontal direction.

First, the overall configuration of the camera device 1 according to the embodiment of the present invention will be described with reference to FIG. The camera device 1 is installed on a crossbar 42 attached to a roof surface of a vehicle (not shown in FIG. 1), and mainly a camera 2 for remote monitoring and the camera 2 is fixed to an object to be installed. It is composed of a camera mounting jig 3 for.

As shown in FIG. 2, the camera 2 includes a camera body 22 for photographing an object to be photographed in a box-shaped casing 21, a router 23 as a communication device, and a power supply device 24 for driving the camera body 22 and the router 23. An exhaust fan 25 for preventing a temperature rise in the housing 21 and a dome cover 27 attached to an opening 26 formed on one surface of the housing 21 are mainly configured.

The camera body 22 is capable of pan, tilt, and zoom control, and is configured by an omnidirectional camera equipped with a panoramic shooting lens 221 capable of shooting 360° images with one unit.

Here, the camera body 22 does not necessarily have to have the panoramic photographing lens 221. As long as 360° omnidirectional shooting is possible, for example, a fisheye lens or a wide-angle lens can be used instead of the panoramic shooting lens 221.

The router 23 enables wireless communication between the camera body 22 and a communication device (not shown). For example, a video image captured by the camera body 22 is passed through a portable terminal device such as a personal computer, a smartphone, or a tablet. It can be seen at all times. Furthermore, the pan, tilt, and zoom of the camera body 22 can be controlled using a mobile terminal.

In the power supply device 24, for example, a sheet-shaped solar cell 241 attached to the outside of the housing 21 is connected by a power cord (not shown). The solar cell 241 generates electric power almost in proportion to the amount of solar radiation, and supplies power to the camera body 22, the router 23, the exhaust fan 25, and the like.

Here, it is not always necessary to use the solar cell 241 as the power supply device 24. However, by using the solar cell 241, the solar cell 241 can be used outdoors for a long period of time, and wiring for supplying power from the outside is not required, so that its installation and maintenance are easy.

The dome cover 27 is made of translucent transparent resin or plastic and has a substantially hemispherical shape, and is attached to the circular opening 26 formed on one surface of the housing 21 so that the bottom portion 271 thereof fits. Has been. That is, the camera body 22 can shoot an object to be photographed through the dome cover 27, and even if the camera body 22 is installed outdoors for a long time, rainwater and dust are prevented from entering the housing 21, including the camera body 22. Can be prevented.

It should be noted that the camera 2 used in the present invention is presumed to be installed so that the top portion 272 of the dome cover 27 faces the installation surface of the camera 2. In this way, by installing the camera 2 so that the top portion 272 of the dome cover 27 points toward the installation surface, the dome cover 27 is directly exposed to rainwater or dust even when used outdoors for a long time in bad weather. There is no such thing, and you can always shoot clear images.

As shown in FIGS. 1 and 3, the camera mounting jig 3 is attached to a base portion 31 installed on an installation surface, a leg portion 32 standing vertically above the base portion 31, and a housing 21 of the camera 2. It is mainly composed of a flange portion 34 that is in contact with and fixed.

The base portion 31 has a flat plate shape, one surface of which is fixed to the installation surface, and the leg portion 32 is fixed to the other surface by a fixing means such as welding. On one surface of the base portion 31, for example, when the base portion 31 is fixed to the roof surface of the vehicle as an installation location of the base portion 31, a fitting recess 33 for fitting into a crossbar 42 provided on the roof surface of the vehicle. Is fixed by a bolt 35 and a nut 36, and a fitting recess 33 is also integrally formed on the other end side.

Here, the base portion 31 does not necessarily have to be configured as a single flat plate. For example, it may be configured such that it is divided into two flat plates, and a first leg portion 321 and a second leg portion 322 described later are fixed to each of the divided flat plates.

The leg portion 32 has a thin side surface portion 323, and is composed of a first leg portion 321 and a second leg portion 322 which have the same shape, and one end of which is welded and fixed to the other surface of the base portion 31. It is integrated.

Here, the leg portion 32 does not necessarily have to be divided into the first leg portion 321 and the second leg portion 322. For example, it may be composed of one leg portion 32, or may have three or more leg portions 32. However, if the number of legs 32 is one, the rigidity for supporting the heavy camera 2 may be insufficient, and it may not be possible to use the camera for a long time. On the other hand, when the leg portion 32 is composed of three or more parts, the number of parts increases and the installation space of the leg portion 32 may be insufficient when the leg portion 32 is installed in a space-saving manner. Therefore, in order to stably support the camera 2 in a space-saving manner, it is preferable that the leg portion 32 is composed of two legs.

Further, the first leg 321 and the second leg 322 do not necessarily have to be fixed to the base 31 by welding. For example, one end of the first leg portion 321 and the second leg portion 322 may be inserted and fixed in the slit hole formed in the base portion 31, and may be appropriately selected from other known fixing means. be able to.

Further, the first leg portion 321 and the side surface portion 323 of the second leg portion 322 do not necessarily need to be thin. In this respect, the thicker the side surface portion 323 is, the more advantageous it is in terms of rigidity, but on the other hand, the range of reflection on the image by the camera 2 is also large. In the present invention, it is preferable that the side surface portion 323 be as thin as possible from the viewpoint of minimizing the area of the camera mounting jig 3 reflected in the image.

On the other ends of the first leg portion 321 and the second leg portion 322 which are erected from the base portion 31, a flange portion 34 having a bolt insertion hole 341 formed at a predetermined position is installed. The flange portion 34 is brought into contact with the casing 21 so that the bolt insertion hole 341 formed in the flange portion 34 and the bolt insertion hole (not shown) formed in the casing 21 of the camera 2 are aligned with each other, and the bolt 4 is attached. By inserting it, the camera mounting jig 3 and the camera 2 can be firmly fixed.

FIG. 4 is a plan view of the camera 2 mounted on the camera mounting jig 3. As shown in FIG. 4, the first leg portion 321 and the second leg portion 322 extend along the radial direction of the bottom portion 271 of the dome cover 27 in which the respective side surface portions 323 are attached to the opening 26 of the housing 2. Are arranged as follows. As described above, the side surfaces 323 and 323 of the first leg 321 and the second leg 322 are arranged along the radial direction of the bottom portion 271 of the dome carver 27, so that the camera body 22 is horizontally oriented. When taking a picture of an object while rotating (panning) 360 degrees, the reflection of the first leg 321 and the second leg 322 on the camera 2 can be avoided as much as possible, so that a clear image is taken. It is possible.

As shown in FIG. 4, the first leg portion 321 and the second leg portion 322 are arranged such that the side surface portions 323 and 323 of the first leg portion 321 and the second leg portion 322 are arranged on the base portion 31. It is set in the range of 30° to 70° in plan view.

Here, the angle formed by the side surfaces 323 and 323 of the first leg 321 and the second leg 322 does not necessarily have to be set in the range of 30° to 70°. However, when the angle formed by the side surfaces 323 and 323 of the first leg 321 and the second leg 322 is set in the range of 30° to 70°, the camera 2 is supported even in a space-saving manner. In addition, it is possible to minimize reflection of the first leg 321 and the second leg 322 on the camera 2. Therefore, it is preferable that the angle formed by the side surface portions 323 and 323 of the first leg portion 321 and the second leg portion 322 is 30° to 70°.

FIG. 5 is a diagram showing a state in which the camera device 1 is attached to the roof surface 41 of the vehicle 4. A crossbar 42 is provided on the roof surface 41 of the vehicle 4. The fitting recess 33 fixed to one surface of the base portion 32 of the camera mounting jig 3 is fitted to the crossbar 42, so that the camera mounting jig 3 is firmly fixed to the vehicle 4.

The power supply to the camera 2 may be supplied from the solar cell 241 attached to the housing of the camera 2 as described above. For example, as shown in FIG. It may be configured to be supplied from a lithium ion battery 43 connected to a lead battery (not shown). In addition, when the vehicle 4 to be installed is an electric vehicle, power can be directly supplied from a lithium-ion battery mounted on the vehicle.

As described above, when the camera device 1 is mounted on the vehicle 4, by receiving power supply from the lithium-ion battery 43, even when the power supply by the solar cell 241 becomes unstable, for example, in bad weather, Since the power can be stably supplied to the camera 2, it is possible to shoot a clear image for a long time without interruption in the shooting operation.

The image captured by the camera 2 installed in the vehicle 4 is constantly sent by the router 23 mounted in the camera 2 to, for example, a mobile terminal device mounted in the vehicle 4. The driver or fellow passenger of the vehicle 4 can monitor the surroundings while checking the image sent to the mobile terminal, and can early detect a suspicious person or a change in the surrounding environment that cannot be visually confirmed. Become.

As described above, the camera mounting jig and the camera device to which the present invention is applied can prevent unnecessary objects from being reflected in the image captured by the camera, and can clearly capture the required image. ing.
