Description

カメラ取付治具、およびカメラ装置Camera mounting jig and camera device
　本発明は、カメラ取付治具、およびカメラ装置に関する。詳しくは、カメラにより撮影される映像に不要な対象物が映り込むことを防止し、必要な映像を鮮明に撮影することができるカメラ取付治具、およびカメラ装置に係るものである。 The present invention relates to a camera mounting jig and a camera device. Specifically, the present invention relates to a camera mounting jig and a camera device that can prevent unnecessary objects from being reflected in an image captured by a camera and can capture a necessary image clearly.
　近年、インターネットの普及により簡易にデータを送信できることから、例えば遠隔地の特定の場所に設置した監視カメラとインターネット網を利用したネットワーク型の監視カメラシステムが普及している。これらネットワーク型の監視カメラシステムは、特に自然災害などの情報提供や土木建築現場の作業進捗状況の把握のための情報提供、あるいは工場、店舗内での不審者等のモニタリングなど種々の場所で広く用いられている（特許文献１）。 In recent years, since data can be easily transmitted due to the spread of the Internet, for example, a surveillance camera installed at a specific place in a remote place and a network-type surveillance camera system using the Internet network have been widely used. These network-type surveillance camera systems are widely used in various places such as providing information on natural disasters, providing information for grasping work progress at civil engineering construction sites, and monitoring suspicious persons in factories and stores. (Patent Document 1).
　このような監視カメラは、天井や壁に埋め込んで設置する場合には、例えば特許文献２に開示されているような取付治具が使用される。具体的には、図６に示すように、建物の取付面に対して略平行かつ離間配置された上枠５０１と下枠５０２を有し、上枠５０１と下枠５０２は連結部材５０３により連結されている。監視用のカメラは上枠５０１と下枠５０２との間に配置される取付部材５０４に取り付けられる。そして、この取付部材５０４は、上枠５０１と下枠５０２との間において昇降手段５０５により昇降可能であり、所定の高さ位置において固定されるものとなっている。 When installing such a surveillance camera embedded in a ceiling or a wall, for example, a mounting jig as disclosed in Patent Document 2 is used. Specifically, as shown in FIG. 6, an upper frame 501 and a lower frame 502 are arranged substantially parallel to and spaced from the mounting surface of the building, and the upper frame 501 and the lower frame 502 are connected by a connecting member 503. Has been. The monitoring camera is attached to an attachment member 504 disposed between the upper frame 501 and the lower frame 502. The mounting member 504 can be moved up and down between the upper frame 501 and the lower frame 502 by the lifting means 505, and is fixed at a predetermined height position.
　また、監視用のカメラを天井や壁のない河川等の屋外に設置する場合には、図７に示すように監視対象となる特定位置に三脚（または一脚）６０１を立設させ、この三脚６０１の所定の高さ位置でカメラ６０２を強固に固定する方法が用いられている。 Further, when the surveillance camera is installed outdoors such as a river without a ceiling or a wall, a tripod (or a 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 601 is used.
　このような監視用のカメラは、監視対象となる特定位置に固定され、常時その特定場所の監視を行うために用いられているものである。一方、河川や工場のような広範囲の敷地内においては、パン、チルト、およびズームの制御が可能な全方位型のカメラを使用しても、１台のカメラで監視できる対象範囲は限られてしまい、監視対象領域の隅々まで監視することはできない。そのため、複数のカメラを一定間隔毎に設置し、各カメラが追跡対象の映像を捕捉する監視システムが提案されている（特許文献３）。 Such a camera for monitoring is fixed at a specific position to be monitored and is used to constantly monitor the specific location. 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 not possible to monitor every corner of the monitoring target area. Therefore, a monitoring system in which a plurality of cameras are installed at regular intervals and each camera captures an image to be tracked has been proposed (Patent Document 3).
　しかしながら、特許文献３に開示の技術においては、複数のカメラを設置する必要があるため、カメラの設置コストが増加するという課題がある。さらに、各カメラを連携させるためのシステム構成も複雑となり、システム障害が発生した際には、連携システムが途絶えてしまい、監視対象の追跡ができなくなるという課題も有している。 However, in the technique disclosed in Patent Document 3, since it is necessary to install a plurality of cameras, there is a problem that the installation cost of the cameras increases. Furthermore, the system configuration for linking the cameras is complicated, and when a system failure occurs, the linked system is interrupted, and there is a problem that the monitoring target cannot be tracked.
　以上のような課題に対して、例えば河川や工場内を巡回する巡回車に１台の全方位型のカメラを取り付け、監視対象となる敷地内を巡回車により巡回すると同時に、巡回車に取り付けたカメラにより周囲の状況を撮影することが考えられる。そして、このような巡回車へのカメラの取り付けに際しては専用の取付治具が必要となるが、例えば特許文献４、および特許文献５には、移動体としての車両にカメラを取り付けるための取付治具が開示されている。 In response to the above problems, for example, one omnidirectional camera is attached to a patrol car that patrols a river or factory, and the patrol car patrols the site to be monitored and is attached to the patrol car at the same time. It is conceivable to photograph the surrounding situation with a camera. For mounting the camera on such a patrol car, a dedicated mounting jig is required. For example, Patent Document 4 and Patent Document 5 disclose an mounting jig for mounting the camera on a vehicle as a moving body. A tool is disclosed.
　例えば、特許文献４に開示の取付治具は、図８（ａ）に示すように、柱部材７０１の下端が車両７０４としての電動カートの後部側に取り付けられ、柱部材７０１の下端よりも高い位置に柱部材７０１の上端が位置し、この上端にカメラ７０３を取り付けるための取付台７０２が固定されている。従って、特許文献４によれば、柱部材７０１の高さ分だけカメラ７０３と車両７０４とが離れるため、カメラ７０３により撮影される映像に車両７０４やカメラ７０３の取付台７０２が映り込むことを回避でき、全方位において鮮明な映像を撮影することが可能なものとなっている。 For example, in the mounting jig disclosed in Patent Document 4, the lower end of the column member 701 is attached to the rear side of the electric cart as the vehicle 704 and is higher than the lower end of the column member 701 as shown in FIG. The upper end of the column member 701 is positioned at a position, and a mounting base 702 for mounting the camera 703 is fixed to the upper end. Therefore, according to Patent Document 4, since the camera 703 and the vehicle 704 are separated from each other by the height of the column member 701, it is avoided that the vehicle 704 and the mounting base 702 of the camera 703 are reflected in the video imaged by the camera 703. It is possible to shoot clear images in all directions.
　また、特許文献５に開示の取付治具は、図８（ｂ）に示すように、車両８０４のルーフ面８０５のキャリア８０３にスライド可能なマウント８０１が取り付けられ、このマウント８０１に台座８０２を介してカメラ８０６が取り付けられる構造となっている。この特許文献５によれば、特許文献４と同じく、カメラ８０６により撮影される映像に車両８０４や台座８０２が映り込むことを回避でき、全方位において鮮明な映像を撮影することが可能なものとなっている。 Further, as shown in FIG. 8B, the mounting jig disclosed in Patent Document 5 has a slidable mount 801 attached to a carrier 803 of a roof surface 805 of a vehicle 804, and a pedestal 802 is attached to the mount 801. Thus, the camera 806 is attached. According to Patent Document 5, as in Patent Document 4, it can be avoided that the vehicle 804 and the base 802 are reflected in the image captured by the camera 806, and a clear image can be captured in all directions. It has become.

　ところで、特許文献４、および特許文献５に記載の取付治具は、レンズを含むカメラ本体を保護するための、例えば半球体状であり透光性のドームカバーが設置面とは反対方向である上方（空側）を向くように設置されることを前提としたものである。このように、透明なドームカバーを上方に向けるようにカメラを設置すると、前記した通り、車両や取付治具の映り込みを防止することはできるものの、悪天候時等においては、ドームカバーは直接に風雨等に曝されることになる。 Incidentally, the mounting jigs described in Patent Document 4 and Patent Document 5 are, for example, hemispherical and have a translucent dome cover in a direction opposite to the installation surface for protecting the camera body including the lens. It is assumed that it is installed so as to face upward (empty side). As described above, when the camera is installed so that the transparent dome cover faces upward, the reflection of the vehicle and the mounting jig can be prevented as described above. You will be exposed to wind and rain.
　長時間にわたって風雨等により直接に曝されたドームカバーには、雨水等に含まれる泥や埃が付着するとともに、ドームカバー表面の亀裂発生等の原因となってしまう。そして、ドームカバーに付着した泥や埃または亀裂は、当然ながらカメラにより撮影された映像に映り込んでしまうため、鮮明な映像を撮影することができない虞がある。 The dome cover that has been directly exposed to wind and rain over a long period of time will adhere to mud and dust contained in rainwater and cause cracks on the surface of the dome cover. And since mud, dust, or a crack adhering to the dome cover is reflected in the video imaged by the camera as a matter of course, there is a possibility that a clear video image cannot be taken.
　そのため作業者は、定期的にドームカバーの清掃や亀裂の有無を確認する必要があるが、作業上の負担が非常に大きいものとなっている。一方、ドームカバーが風雨等に直接曝されないようにするには、ドームカバーを下向き（地面側）になるようにカメラを車両のルーフ面等に取り付ける必要がある。しかしながら、天井面の存在しない車両のルーフ面に対して、ドームカバーが下向きに向くようにするには、カメラを上方から吊り下げるための取付治具が必要となるが、この場合、カメラ本体と取付治具は必然的に交差部分が生じるため、カメラにより撮影される映像には、必ず取付治具の一部が映り込むことになるという課題を有している。 Therefore, it is necessary for the worker to periodically clean the dome cover and check for cracks, but the work burden is very large. On the other hand, in order to prevent the dome cover from being directly exposed to wind and rain, it is necessary to attach the camera to the roof surface of the vehicle so that the dome cover faces downward (on the ground side). However, in order for the dome cover to face downward with respect to the roof surface of the vehicle where there is no ceiling surface, a mounting jig for hanging 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 always reflected in an image taken by the camera.
　本発明は、以上の点に鑑みて創案されたものであり、カメラにより撮影される映像に不要な対象物が映り込むことを防止し、必要な映像を鮮明に撮影することができるカメラ取付治具、およびカメラ装置を提供することを目的とする。 The present invention was devised in view of the above points, and it is possible to prevent unnecessary objects from being reflected in an image captured by a camera and to capture a necessary image clearly. It is an object to provide a tool and a camera device.
　前記の目的を達成するために、本発明のカメラ取付治具は、対象物を撮影するカメラ本体を含み所定の位置に開口部が形成された筐体と、底部が該筐体の開口部に嵌合されるとともに、前記カメラ本体を覆う透光性の半球体状のドームカバーとを有するカメラのカメラ取付治具であって、一面が設置面に固定され、他面が前記ドームカバーの頂部と所定の距離だけ離間して対峙するベース部と、前記ドームカバーの底部の半径方向に沿った側面部を有し、一端が前記ベース部、他端が前記筐体に固定された薄板状の脚部とを備える。 In order to achieve the above object, a camera mounting jig according to the present invention includes a camera body for photographing an object, a housing having an opening formed at a predetermined position, and a bottom portion at the opening of the housing. A camera mounting jig for a camera having a translucent hemispherical dome cover that is fitted and covers the camera body, wherein one surface is fixed to the installation surface and the other surface is the top of the dome cover And a base portion that is opposed to and spaced apart by a predetermined distance, and a side surface portion along the radial direction of the bottom portion of the dome cover, one end being a base plate and the other end being fixed to the housing And a leg.
　ここで、カメラが、対象物を撮影するカメラ本体を含み所定の位置に開口部が形成された筐体を備えていることにより、カメラ本体を筐体内に取り付けることができるとともに、カメラ本体を外力から保護することができる。 Here, since the camera includes a camera body that shoots an object and includes a housing having an opening formed at a predetermined position, the camera body can be mounted in the housing and the camera body can be externally applied. Can be protected from.
　また、カメラが、底部が筐体の開口部に嵌合されるとともに、カメラ本体を覆う透光性の半球体状のドームカバーを備えていることにより、カメラ本体を外力から保護することができるとともに、透光性のドームカバーを通じて撮影対象を撮影することができる。 In addition, the camera body can be protected from external force by including a translucent hemispherical dome cover that covers the camera body while the bottom is fitted into the opening of the housing. At the same time, the subject can be photographed through the translucent dome cover.
　また、カメラ取付治具が、一面が設置面に固定されるベース部を備えることにより、このベース部を設置面に対して固定することができる。 Also, the camera mounting jig includes a base portion whose one surface is fixed to the installation surface, so that the base portion can be fixed to the installation surface.
　また、ドームカバーの頂面とベース部の他面が、所定の距離だけ離間して対峙するように配置されていることにより、カメラを固定したカメラ取付治具を設置面に固定した場合、ドームカバーが上方（空側）とは反対方向の地面方向である設置面を指向するため、ドームカバーが雨水や埃に直接曝されず、ドームカバーへの泥や埃の付着を低減することができる。 In addition, since the top surface of the dome cover and the other surface of the base portion are arranged so as to face each other with a predetermined distance, the dome is fixed when the camera mounting jig that fixes the camera is fixed to the installation surface. Since the cover is directed to the installation surface, which is the ground direction opposite to the upper side (empty side), the dome cover is not directly exposed to rainwater and dust, and adhesion of mud and dust to the dome cover can be reduced. .
　また、一端がベース部、他端が筐体に固定された脚部を備えることにより、カメラを設置面に対して強固に固定することができる。 Moreover, the camera can be firmly fixed to the installation surface by providing a leg portion with one end fixed to the base and the other end fixed to the housing.
　また、脚部が、その側面部がドームカバーの底部の半径方向に沿うように配置された薄板状から構成されることにより、カメラにより対象物を撮影する際に、脚部のカメラ本体への映り込みを最小限に抑えることができる。 Further, when the leg portion is formed of a thin plate shape whose side surface portion is arranged along the radial direction of the bottom portion of the dome cover, when the object is photographed by the camera, the leg portion is attached to the camera body. Reflection can be minimized.
　また、脚部が互いに離間した位置でベース部の他面から鉛直上方に立設する第１の脚部と第２の脚部を含む場合には、より安定した状態でカメラを支持することができるため、撮影時のブレ等が少なく、鮮明な映像を撮影することができる。 Further, when the first leg portion and the second leg portion standing vertically upward from the other surface of the base portion at positions where the leg portions are separated from each other, the camera can be supported in a more stable state. Therefore, it is possible to shoot a clear image with little blurring during shooting.
　また、第１の脚部の側面部、および第２の脚部の側面部がベース部の平面視において互いに略３０°～７０°をなすように配設されている場合には、省スペース内においてもカメラを支持することができるとともに、脚部のカメラ本体への映り込みを最小限におさえることができる。 Further, when the side surface portion of the first leg portion and the side surface portion of the second leg portion are arranged so as to form approximately 30 ° to 70 ° with respect to each other in a plan view of the base portion, space saving is achieved. It is possible to support the camera at the same time and to minimize the reflection of the legs on the camera body.
　なお、第１の脚部の側面部、および第２の脚部の側面部のなす角度がベース部の平面視において３０°よりも小さい場合には、カメラを支持する安定度が劣り、７０°よりも大きい場合には、比較的広い取付スペースが必要となり、省スペース内でのカメラの設置が困難なものとなる。 In addition, when the angle formed by the side surface portion of the first leg portion and the side surface portion of the second leg portion is smaller than 30 ° in plan view of the base portion, the stability of supporting the camera is inferior, and 70 ° If it is larger than that, a relatively wide mounting space is required, which makes it difficult to install the camera in a space-saving manner.
　また、ベース部の一面に、設置面に嵌合可能な嵌合凹部を有する場合には、例えばカメラ取付治具を車両のルーフ面に取り付ける場合、ルーフ面に設置されたクロスバーに対して、この嵌合凹部を嵌合することで、容易、かつ強固にカメラ取付治具を設置することができる。 In addition, when having a fitting recess that can be fitted to the installation surface on one surface of the base portion, for example, when attaching the camera mounting jig to the roof surface of the vehicle, the crossbar installed on the roof surface By fitting the fitting recess, the camera mounting jig can be easily and firmly installed.
　また、第１の脚部と第２の脚部の所定の高さ位置に架設され、筐体に当接されるフランジ部を有する場合には、このフランジによりカメラの筐体に対する設置面積が増大し、カメラとカメラ取付治具の取付強度を高め、より安定した状態でカメラを支持することができるとともに、撮影時のブレ等が少なく、鮮明な映像を撮影することができる。 In addition, when the first leg portion and the second leg portion are provided at a predetermined height position and have a flange portion that comes into contact with the housing, the flange increases the installation area of the camera with respect to the housing. In addition, the mounting strength between the camera and the camera mounting jig can be increased, the camera can be supported in a more stable state, and a clear image can be captured with less blurring during shooting.
　また、フランジ部には、取付ボルトが挿通可能な貫通孔が形成されている場合には、ボルトを介してカメラとカメラ取付治具を脱着することができるため、カメラのカメラ取付治具への脱着作業が容易なものとなる。 In addition, when the through hole into which the mounting bolt can be inserted is formed in the flange portion, the camera and the camera mounting jig can be attached and detached via the bolt, so that the camera can be attached to the camera mounting jig. Desorption work is easy.
　前記の目的を達成するために、本発明のカメラ装置は、対象物を撮影するカメラ本体を含み所定の位置に開口部が形成された筐体、底部が該筐体の開口部に嵌合されるとともに、前記カメラ本体を覆う透光性の半球体状のドームカバーを有するカメラと、一面が設置面に固定され、他面が前記ドームカバーの頂面と所定の距離だけ離間して対峙するベース部、前記ドームカバーの底部の半径方向に沿った側面部を含み、一端が前記ベース部、他端が前記筐体に固定された薄板状の脚部を有するカメラ取付治具とを備える。 In order to achieve the above object, a camera device of the present invention includes a camera body for photographing an object, a housing having an opening formed at a predetermined position, and a bottom portion fitted into the opening of the housing. And a camera having a translucent hemispherical dome cover that covers the camera body, and one surface is fixed to the installation surface, and the other surface is opposed to the top surface of the dome cover with a predetermined distance. A camera mounting jig including a base portion and a side surface portion along the radial direction of the bottom portion of the dome cover, one end of which is a base portion and the other end is a thin plate-like leg portion fixed to the housing;
　ここで、カメラが、対象物を撮影するカメラ本体を含み所定の位置に開口部が形成された筐体を備えていることにより、カメラ本体を筐体内に取り付けることができるとともに、カメラ本体の一部を外力から保護することができる。 Here, since the camera includes a camera body that shoots an object and includes a housing having an opening formed at a predetermined position, the camera body can be mounted in the housing and one of the camera bodies can be mounted. The part can be protected from external force.
　また、カメラが、底部が筐体の開口部に嵌合されるとともに、カメラ本体を覆う透光性の半球体状のドームカバーを備えていることにより、カメラ本体を外力から保護することができるとともに、ドームカバーを通じて撮影対象を撮影することができる。 In addition, the camera body can be protected from external force by including a translucent hemispherical dome cover that covers the camera body while the bottom is fitted into the opening of the housing. At the same time, the subject can be photographed through the dome cover.
　また、カメラ取付治具が、一面が設置面に固定されるベース部を備えることにより、このベースを設置面に対して固定することができる。 Further, the camera mounting jig includes a base portion whose one surface is fixed to the installation surface, whereby the base can be fixed to the installation surface.
　また、ドームカバーの頂面とベース部の他面が、所定の距離だけ離間して対峙するように配置されていることにより、カメラを固定したカメラ取付治具を設置面に固定した場合、ドームカバーが上方（空側）とは反対方向の地面方向である設置面を指向するため、ドームカバーが雨水や埃に直接曝されず、ドームカバーへの泥や埃の付着を低減することができる。 In addition, since the top surface of the dome cover and the other surface of the base portion are arranged so as to face each other with a predetermined distance, the dome is fixed when the camera mounting jig that fixes the camera is fixed to the installation surface. Since the cover is directed to the installation surface, which is the ground direction opposite to the upper side (empty side), the dome cover is not directly exposed to rainwater and dust, and adhesion of mud and dust to the dome cover can be reduced. .
　また、一端がベース部、他端が筐体に固定された脚部を備えることにより、カメラを設置面に対して強固に固定することができる。 Moreover, the camera can be firmly fixed to the installation surface by providing a leg portion with one end fixed to the base and the other end fixed to the housing.
　また、脚部が、その側面部がドームカバーの底部の半径方向に沿うように配置された薄板状から構成されることにより、カメラにより対象物を撮影する際に、脚部のカメラ本体への映り込みを最小限に抑えることができる。 Further, when the leg portion is formed of a thin plate shape whose side surface portion is arranged along the radial direction of the bottom portion of the dome cover, when the object is photographed by the camera, the leg portion is attached to the camera body. Reflection can be minimized.
　また、脚部が互いに離間した位置でベース部の他面から鉛直上方に立設する第１の脚部と第２の脚部を含む場合には、より安定した状態でカメラを支持することができるため、撮影時のブレ等が少なく、鮮明な映像を撮影することができる。 Further, when the first leg portion and the second leg portion standing vertically upward from the other surface of the base portion at positions where the leg portions are separated from each other, the camera can be supported in a more stable state.

It is possible to support the camera at the same time and to minimize the reflection of the legs on the camera body.
　なお、第１の脚部の側面部、および第２の脚部の側面部のなす角度がベース部の平面視において３０°よりも小さい場合には、カメラを支持する安定度が劣り、７０°よりも大きい場合には、比較的広い取付スペースが必要となり、省スペース内でのカメラの設置が困難なものとなる。 In addition, when the angle formed by the side surface portion of the first leg portion and the side surface portion of the second leg portion is smaller than 30 ° in plan view of the base portion, the stability of supporting the camera is inferior, and 70 ° If it is larger than that, a relatively wide mounting space is required, which makes it difficult to install the camera in a space-saving manner.
　本発明に係るカメラ取付治具、およびカメラ装置は、カメラにより撮影される映像に不要な対象物が映り込むことを防止し、必要な映像を鮮明に撮影することができる。 The camera mounting jig and the camera device according to the present invention can prevent unnecessary objects from being reflected in an image captured by the camera and can capture a necessary image clearly.

　以下、カメラ取付治具、およびカメラ装置に関する本発明の実施の形態について、図面を参照しながら説明し、本発明の理解に供する。なお、各図においては、説明の便宜上、カメラ取付治具３を設置面に設置した際の、設置面から上方に向かう方向を上方向と定義し、上方向の反対方向を下方向と定義し、上方向、および下方向により表される軸方向を鉛直方向と定義し、鉛直方向と垂直な軸方向を水平方向とそれぞれ定義する。 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 for understanding of the present invention. In each figure, for convenience of explanation, when the camera mounting jig 3 is installed on the installation surface, the upward direction from the installation surface is defined as the upper direction, and the opposite direction of the upper direction is defined as the lower direction. An axial direction represented by an upward direction and a downward direction is defined as a vertical direction, and an axial direction perpendicular to the vertical direction is defined as a horizontal direction.
　まず、本発明の実施形態に係るカメラ装置１の全体構成について図１を用いて説明する。カメラ装置１は、図１には図示しない車両のルーフ面に取り付けられたクロスバー４２に設置されるものであり、主に遠隔監視用のカメラ２と、このカメラ２を設置対象物に固定するためのカメラ取付治具３から構成されている。 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 fixes a camera 2 for remote monitoring and the camera 2 to an installation object. It is comprised from the camera mounting jig 3 for this.
　カメラ２は、図２に示すように、箱型の筐体２１内に撮影対象を撮影するカメラ本体２２、通信用機器としてのルータ２３、カメラ本体２２とルータ２３を駆動するための電源装置２４、筐体２１内の温度上昇を防止するための排気ファン２５、および筐体２１の一面に形成された開口部２６に取り付けられたドームカバー２７から主に構成されている。 As shown in FIG. 2, the camera 2 includes a camera body 22 that captures a subject 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. The exhaust fan 25 for preventing temperature rise in the housing 21 and the dome cover 27 attached to the opening 26 formed on one surface of the housing 21 are mainly configured.
　カメラ本体２２は、パン、チルト、およびズーム制御が可能なものであり、１つのユニットにて３６０°の映像を撮影することができるパノラマ撮影レンズ２２１を搭載した全方位カメラによって構成されている。 The camera body 22 is capable of panning, tilting, and zooming control, and is composed of an omnidirectional camera equipped with a panoramic shooting lens 221 that can shoot a 360 ° video with one unit.
　ここで、必ずしも、カメラ本体２２はパノラマ撮影レンズ２２１を有している必要はない。３６０°の全方位の撮影が可能なものであれば、例えばパノラマ撮影レンズ２２１に代えて、魚眼レンズ、または広角レンズを用いることもできる。 Here, the camera body 22 does not necessarily need to have the panoramic photographing lens 221. For example, a fish-eye lens or a wide-angle lens can be used instead of the panoramic photographing lens 221 as long as 360 ° omnidirectional photographing is possible.
　ルータ２３は、カメラ本体２２と図示しない通信機器との間で無線通信を可能とするものであり、例えばカメラ本体２２により撮影された映像を、パーソナルコンピュータ、スマートフォン、またはタブレット等の携帯端末機を通じて常時見ることができるものとなっている。さらに、携帯端末機を使用してカメラ本体２２のパン、チルト、ズーム制御も可能なものとなっている。 The router 23 enables wireless communication between the camera body 22 and a communication device (not shown). For example, an image captured by the camera body 22 is transmitted through a portable terminal such as a personal computer, a smartphone, or a tablet. It can be seen at any time. Furthermore, panning, tilting, and zooming control of the camera body 22 can be performed using a portable terminal.
　電源装置２４は、例えば筐体２１の外側に貼着されたシート状の太陽電池２４１が図示しない電源コードで接続される。太陽電池２４１は日射量にほぼ比例して電力を発生し、カメラ本体２２、ルータ２３、および排気ファン２５等に電源を供給する。 For example, a sheet-like solar cell 241 attached to the outside of the housing 21 is connected to the power supply device 24 by a power cord (not shown). The solar cell 241 generates 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.
　ここで、必ずしも、電源装置２４として太陽電池２４１を使用する必要はない。但し、太陽電池２４１を使用することにより、長期間の屋外での使用が可能になるとともに、外部からの電源供給のための配線も不要となるため、その設置やメンテナンスが容易なものとなる。 Here, it is not always necessary to use the solar cell 241 as the power supply device 24. However, the use of the solar battery 241 enables outdoor use for a long period of time and eliminates the need for wiring for supplying power from the outside, which facilitates installation and maintenance.
　ドームカバー２７は透光性のある透明な樹脂、またはプラスチック製の略半球体状からなり、筐体２１の一面に形成された円形の開口部２６に、その底部２７１が嵌合するように取り付けられている。即ち、カメラ本体２２は、このドームカバー２７を通じて撮影対象を撮影可能となっているとともに、例え屋外に長時間設置したとしても、カメラ本体２２を含め、筐体２１内に雨水や埃の侵入を防止することができる。 The dome cover 27 is made of a translucent transparent resin or plastic substantially hemispherical, and is attached so that the bottom portion 271 fits into a circular opening 26 formed on one surface of the housing 21. It has been. In other words, the camera body 22 can shoot a subject to be photographed through the dome cover 27, and even if it is installed outdoors for a long time, rainwater and dust intrude into the housing 21 including the camera body 22. Can be prevented.
　なお、本発明において使用するカメラ２は、ドームカバー２７の頂部２７２がカメラ２の設置面を指向するように設置されるものを前提とする。このように、ドームカバー２７の頂部２７２が設置面を指向するようにカメラ２を設置することで、悪天候時に屋外で長時間使用したとしても、ドームカバー２７が雨水や埃に直接曝されることがなく、常に鮮明な映像を撮影することができるものとなっている。 It should be noted that the camera 2 used in the present invention is premised on being installed such that the top 272 of the dome cover 27 is directed to 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 faces the installation surface, the dome cover 27 is directly exposed to rainwater and dust even when used outdoors for a long time in bad weather. There is no, and it can always shoot clear video.
　カメラ取付治具３は図１、および図３に示すように、設置面に設置されるベース部３１、ベース部３１から鉛直方向上方に立設する脚部３２、カメラ２の筐体２１に当接され固定されるフランジ部３４から主に構成されている。 As shown in FIGS. 1 and 3, the camera mounting jig 3 contacts the base portion 31 installed on the installation surface, the leg portion 32 erected vertically from the base portion 31, and the housing 21 of the camera 2. It is mainly comprised from the flange part 34 which is contact | connected and fixed.
　ベース部３１は一面が設置面に固定され、他面に脚部３２が溶接等の固定手段で固定された平板状からなるものである。ベース部３１の一面には、一端側に例えばベース部３１の設置場所として車両のルーフ面に固定する場合において、車両のルーフ面に設けられたクロスバー４２に嵌合させるための嵌合凹部３３が、ボルト３５、ナット３６により固定され、他端側には同じく嵌合凹部３３が一体形成されている。 The base portion 31 has a flat plate shape in which one surface 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 the installation location of the base portion 31, a fitting recess 33 for fitting with a cross bar 42 provided on the roof surface of the vehicle. However, it is fixed by a bolt 35 and a nut 36, and a fitting recess 33 is integrally formed on the other end side.
　ここで、必ずしも、ベース部３１は一枚の平板状から構成されている必要はない。例えば、二枚の平板に分割し、分割した各平板に後述する第１の脚部３２１、および第２の脚部３２２を固定するように構成してもよい。 Here, the base part 31 does not necessarily have to be composed of a single flat plate. For example, the first leg portion 321 and the second leg portion 322 which will be described later may be fixed to each of the divided flat plates.
　脚部３２は、薄厚の側面部３２３を有し、それぞれが同一形状である第１の脚部３２１と第２の脚部３２２から構成され、その一端がベース部３１の他面に溶接固定され一体化されている。 The leg part 32 has a thin side part 323, each of which is composed of a first leg part 321 and a second leg part 322 having the same shape, one end of which is fixed to the other surface of the base part 31 by welding. It is integrated.
　ここで、必ずしも、脚部３２は第１の脚部３２１と第２の脚部３２２に分割して構成されている必要はない。例えば１本の脚部３２から構成されていてもよく、また３本以上の脚部３２を有していてもよい。ただし、脚部３２が１本の場合には、重量のあるカメラ２を支持するための剛性が不足し、長時間の使用ができない虞がある。一方、脚部３２として３本以上から構成されている場合には、部品点数が多くなるとともに、省スペース内に設置する際に、脚部３２の配置スペースが不足する虞がある。従って、省スペース内において安定してカメラ２を支持するためには、脚部３２は２本から構成されていることが好ましい。 Here, the leg part 32 does not necessarily need to be divided into the first leg part 321 and the second leg part 322. For example, it may be composed of a single leg 32 or may have three or more legs 32. However, when the number of the leg portions 32 is one, the rigidity for supporting the heavy camera 2 is insufficient, and there is a possibility that it cannot be used for a long time. On the other hand, when the leg portion 32 is composed of three or more pieces, the number of parts is increased, and there is a possibility that the arrangement space of the leg portion 32 is insufficient when 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 pieces.
　また、必ずしも、第１の脚部３２１、および第２の脚部３２２のベース部３１への固定は溶接固定されている必要はない。例えば、ベース部３１に形成されたスリット孔に第１の脚部３２１、および第２の脚部３２２の一端を挿入して固定するようにしてもよく、その他の公知の固定手段から適宜選択することができる。 Also, the first leg 321 and the second leg 322 are not necessarily 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 a slit hole formed in the base portion 31, or may be appropriately selected from other known fixing means. be able to.
　また、必ずしも、第１の脚部３２１、および第２の脚部３２２の側面部３２３は薄厚である必要はない。この点、側面部３２３の厚みは、厚ければそれだけ剛性面では有利であるが、反面、カメラ２による映像への映り込み範囲も大きくなる。本発明においては、カメラ取付治具３の映像への映り込み面積をなるべく小さくするという観点から、可能な限り側面部３２３の厚みは薄厚であることが好ましい。 Further, the first leg portion 321 and the side surface portion 323 of the second leg portion 322 are not necessarily thin. In this respect, the thickness of the side surface portion 323 is advantageous in terms of rigidity as it is thicker. In the present invention, it is preferable that the thickness of the side surface portion 323 is as thin as possible from the viewpoint of minimizing the reflection area of the camera mounting jig 3 on the image.
　ベース部３１から立設された第１の脚部３２１、第２の脚部３２２の他端には、所定の位置にボルト挿通孔３４１が形成されたフランジ部３４が架設されている。このフランジ部３４に形成されたボルト挿通孔３４１と、カメラ２の筐体２１に形成された図示しないボルト挿通孔が合致するようにフランジ部３４を筐体２１に対して当接し、ボルト４を挿通させることで、カメラ取付治具３とカメラ２を強固に固定することができるものとなっている。 At the other end of the first leg part 321 and the second leg part 322 erected from the base part 31, a flange part 34 having a bolt insertion hole 341 formed at a predetermined position is installed. The flange portion 34 is brought into contact with the housing 21 so that the bolt insertion hole 341 formed in the flange portion 34 and the bolt insertion hole (not shown) formed in the housing 21 of the camera 2 coincide with each other. By inserting, the camera mounting jig 3 and the camera 2 can be firmly fixed.
　図４は、カメラ２をカメラ取付治具３に取り付けた状態を平面視した図である。図４に示すように、第１の脚部３２１と第２の脚部３２２は、それぞれの側面部３２３が筐体２の開口部２６に取り付けられたドームカバー２７の底部２７１の半径方向に沿うように配置されている。このように、第１の脚部３２１と第２の脚部３２２の側面部３２３、３２３が、ドームカーバー２７の底部２７１の半径方向に沿うように配置されることにより、カメラ本体２２が水平方向に３６０°回転（パン）しながら撮影対象を撮影するに際して、第１の脚部３２１、第２の脚部３２２のカメラ２への映り込みを極力避けることができるため、鮮明な映像を撮影することが可能となっている。 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 are arranged along the radial direction of the bottom portion 271 of the dome cover 27 in which each side surface portion 323 is attached to the opening portion 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 271 of the dome carver 27, so that the camera body 22 is horizontally oriented. When the subject is photographed while rotating (panning) 360 °, the first leg 321 and the second leg 322 can be avoided from being reflected on the camera 2 as much as possible, so that a clear image is photographed. It is possible.
　なお、図４に示すように、第１の脚部３２１と第２の脚部３２２の配置は、第１の脚部３２１と第２の脚部３２２の側面部３２３、３２３がベース部３１の平面視において３０°～７０°の範囲に設定されている。 As shown in FIG. 4, the arrangement of the first leg portion 321 and the second leg portion 322 is such that the side surface portions 323 and 323 of the first leg portion 321 and the second leg portion 322 are the base portion 31. It is set in the range of 30 ° to 70 ° in plan view.
　ここで、必ずしも、第１の脚部３２１と第２の脚部３２２の側面部３２３、３２３のなす角度は３０°～７０°の範囲に設定されている必要はない。但し、第１の脚部３２１と第２の脚部３２２の側面部３２３、３２３のなす角度が３０°～７０°の範囲に設定されている場合には、省スペース内においてもカメラ２を支持することができるとともに、第１の脚部３２１、および第２の脚部３２２のカメラ２への映り込みを最小限におさえることができる。従って、第１の脚部３２１と第２の脚部３２２の側面部３２３、３２３のなす角度は３０°～７０°であることが好ましい。 Here, the angle formed by the side surfaces 323 and 323 of the first leg 321 and the second leg 322 is not necessarily set in the range of 30 ° to 70 °. However, when the angle formed between 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, the reflection of the first leg 321 and the second leg 322 on the camera 2 can be minimized. Therefore, it is preferable that the angle formed between the side surfaces 323 and 323 of the first leg 321 and the second leg 322 is 30 ° to 70 °.
　図５は、カメラ装置１を、車両４のルーフ面４１に取り付けた状態を示す図である。車両４には、ルーフ面４１にクロスバー４２が設けられている。このクロスバー４２に、カメラ取付治具３のベース部３２の一面に固定された嵌合凹部３３が嵌合して、カメラ取付治具３が車両４に対して強固に固定される。 FIG. 5 is a diagram illustrating a state in which the camera device 1 is attached to the roof surface 41 of the vehicle 4. The vehicle 4 is provided with a cross bar 42 on the roof surface 41. A fitting recess 33 fixed to one surface of the base portion 32 of the camera mounting jig 3 is fitted to the cross bar 42, and the camera mounting jig 3 is firmly fixed to the vehicle 4.
　カメラ２への電源の供給は、前記したように、カメラ２の筐体に貼着された太陽電池２４１から電源供給を受けてもよいが、例えば、図５に示すように、車両４に搭載された図示しない鉛バッテリーと接続されたリチウムイオンバッテリー４３から供給されるように構成されていてもよい。なお、設置対象となる車両４が電気自動車の場合には、搭載されているリチウムイオンバッテリーから直接電源供給を受けることができる。 As described above, the power supply to the camera 2 may be received from the solar cell 241 attached to the housing of the camera 2. 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). When the vehicle 4 to be installed is an electric vehicle, power can be directly supplied from the mounted lithium ion battery.
　このように、車両４にカメラ装置１を搭載する場合には、リチウムイオンバッテリー４３から電源供給を受けることで、例えば悪天候時等において太陽電池２４１による電源供給が不安定となるような場合でも、電源を安定してカメラ２に供給することができるため、撮影作業が途中で途切れたりすることがなく、鮮明な映像を長時間にわたって撮影することが可能となる。 Thus, when the camera device 1 is mounted on the vehicle 4, even when the power supply by the solar cell 241 becomes unstable by receiving power supply from the lithium ion battery 43, 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 of the shooting operation.
　車両４に設置されたカメラ２で撮影された映像は、カメラ２に搭載されているルータ２３により、例えば車両４内に搭載した携帯端末機に常時その映像が送られてくる。車両４の運転者や同乗者は、携帯端末機に送られてくる映像を確認しながら周辺の監視を行い、目視では確認できない不審者や周辺環境の異変等について早期に発見することが可能となる。 The image taken by the camera 2 installed in the vehicle 4 is always sent to a mobile terminal installed in the vehicle 4 by the router 23 installed in the camera 2. The driver and passengers of the vehicle 4 can monitor the surroundings while checking the video sent to the portable terminal, and can quickly detect suspicious persons or changes in the surrounding environment that cannot be visually confirmed. Become.
　以上、本発明を適用したカメラ取付治具、およびカメラ装置は、カメラにより撮影される映像に不要な対象物が映り込むことを防止し、必要な映像を鮮明に撮影することができるものとなっている。 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 an image captured by the camera, and can capture a necessary image clearly. ing.
