【発明が属する技術分野】
本発明は、音声追尾型カメラを利用した介護施設監視システムに関する。
【0002】
【従来の技術】
各種介護施設においては、被介護者の行動把握は最適介護並びに事故防止の観点から非常に重要な事項である。被介護者の居室内やトイレ等の常時周囲に人がいない場所あるいは廊下等で被介護者が倒れたり異常な行動から身体に危険が及ぶようなことがあった場合、近くに介護人あるいは発見者がいないと、すぐに救助や介護ができないこととなる。このような事態を回避するため、介護施設の要所毎に監視カメラを設置し、異常事態の発生をいち早く発見することは広く行われている。
【0003】
また、音声追尾型カメラを侵入者検出に利用する技術も開示されている。すなわち、マイクロフォンを装着したカメラが異常音を検出すると、その音源方向にカメラが向くよう駆動されるようになっている。その後、カメラが撮像した画像から侵入者を検出してその侵入者が撮像されるようにカメラを制御する(特許文献1参照)。

【0005】
【発明が解決しようとする課題】
介護施設において監視カメラにより被介護者の行動を監視するシステムにおいては、常時被介護者の行動を注視しなければならず、被介護者のプライバシーの侵害となることもある。また、常時監視することから、監視のための監視職員を常駐させなければならず、監視職員が異常を検知した場合には担当する介護人へ言葉でその旨を伝達しなければならなかった。また、カメラを可動させることも可能であるが、一定方向への回転動作の場合には視野範囲が限定され、十分な監視効果が期待できない。また自在に必要な箇所へカメラを向けるためには、監視職員によって遠隔操作しなければなかった。
【0006】
音声追尾型カメラによる侵入者の検出技術によっても、介護施設においては被介護者の行動を逐一監視することはプライバシーの侵害となることも多い。本発明は、このような課題を解決するためになされたもので、被介護者のプライバシーを保護しつつ、被介護者に対する真に必要な介護を十分に行い、加えて被介護者の身体に危険が及ぶことのないよう監視することを可能とする介護施設監視システムを提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明に係わる介護施設監視システムは、介護施設内の各所に音声追尾型カメラを配置し、前記介護施設内の被介護者に基いて発生する一定レベル以上の音声に応じて前記音声追尾型カメラを当該音声発生源である被介護者へ向ける如く追尾せしめ、この音声追尾型カメラから収集された映像は予めアクセス権限の登録されている者によってのみ見ることが可能な如く構成されていることを要旨とする。
【0008】
更に本発明に係わる介護施設監視システムは、前記音声追尾型カメラは、少なくとも前記被介護者の居室に配置されており、前記介護施設内にLANが構築されていて、このLANには前記音声追尾型カメラが接続されているとともに、中央処理装置が接続されており、前記音声追尾型カメラによって収集された映像、音声は前記LANを経由して前記中央処理装置に格納される如く構成されていることを要旨とする。
【0009】
更に本発明に係わる介護施設監視システムは、介護施設内に音声追尾型カメラを配置し、この音声追尾型カメラによって前記介護施設内の被介護者の映像、音声を収集し得る如く構成し、前記被介護者の家族の自宅にも前記音声追尾型カメラを配置して、前記介護施設と前記被介護者の家族の自宅との間を通信回線で接続し、前記被介護者と前記家族とが対話し得る如く構成したことを要旨とする。
【0010】
【発明の実施の形態】
以下に本発明の第1実施形態を図を参照して説明する。図1は本発明に係わる介護施設監視システムの主要部を示したものである。介護施設10には事務室11、ナースセンター12、被介護者居室13、娯楽室14、トイレ15、廊下16等から構成されている。事務室11には、中央処理装置17が設置されており、この中央処理装置17は、制御部17a、通信インターフェース部17b、表示部17cから構成されている。また、制御部17aには映像録画・音声録音装置18が接続されている。

【0016】
監視動作を停止する場合には、中央処理装置17にてスケジュール制御をOFFさせるか、任意制御をOFFさせる(S−9)。この結果、音声追尾型カメラ20、21、22、23を停止する(S−10)。
【0017】
このようにして、被介護者が常時普通に生活している状態とは異なる、例えば、転倒、驚きの叫び声をあげる、器具・部材を落とすあるいは破壊する等の通常とは異なる異常事態に起こる音あるいは声をすばやく検出することができる。この結果、異常事態発生から短時間に被介護者のもとへ介護人が到着することが可能となった。また、本システムから得られる映像、音声を入手し得る者を介護人のように、予めアクセス権限を登録しておくようにしてあるので、被介護者のプライバシーは保護される。
【0018】
次に、本発明の第2実施形態を図3を参照して説明する。図1と同一箇所は同一符号を付し、詳細な説明は省略する。本発明に係わる介護施設監視システムは、介護施設10内の被介護者の異常事態監視のみならず、被介護者の家族との交流に利用することが可能である。図3に示した介護施設10は図1に示した介護施設10と同一であって、被介護者28の居室13のみを抽出して示してある。さて、被介護者28の自宅35には家族36がおり、被介護者28も家族も互いに会えることを楽しみにしているものである。そこで、介護施設10と被介護者28の自宅35に音声追尾型カメラ、カメラ用サーバ20、24、33,34を設置して、両者間をインターネット37で接続する。このようにして、双方を音声追尾型カメラ20、33にて撮像し互いに相手方へ映像・音声を送信することによって、リアルタイムの会話が可能となり、被介護者28と家族36の交流が手軽にできるようになる。
【0019】
また、上述した実施形態では異常音の種別・発生源等は特定せず、異常音のレベルのみ通常のレベルから突出したレベルを異常と定めておくようにした。しかしながら、特定の音声を中央処理装置17に登録しておき、登録された音声にのみ反応するように設定することも可能である。例えば、特に注意すべき特定の被介護者の音声を登録しておき、その登録音声を自動追尾のトリガー信号とすることもできる。
【0020】
【発明の効果】
介護施設内の各所に音声追尾型カメラを配置し、異常音を検出すると、この音に追尾して現場の映像・音声を収集することができ、この映像・音声はアクセス権限を登録された介護人等が見ることにより速やかに異常音発生現場へ到着することが可能となった。被介護者のプライバシーを保護しつつ、最適な介護を行うことができるようになった。また、被介護者と家族間の交流を互いに遠隔にいても、映像・音声を伴なって歓談することが可能となった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a care facility monitoring system using a voice tracking camera.
[0002]
[Prior art]
In various nursing homes, understanding the behavior of the cared person is very important from the viewpoint of optimal care and accident prevention. If the cared person falls down or has abnormal behavior that may pose a danger to the body in a place where there is no person around the cared person's living room or toilet, or in a corridor, etc. If there is no one, rescue and nursing care will not be possible immediately. In order to avoid such a situation, it has been widely practiced to install a surveillance camera at each point of a nursing facility to quickly detect the occurrence of an abnormal situation.
[0003]
In addition, a technology that uses a voice tracking camera for intruder detection has been disclosed. That is, when a camera equipped with a microphone detects an abnormal sound, the camera is driven so as to face the sound source. Thereafter, the intruder is detected from the image captured by the camera, and the camera is controlled so that the intruder is imaged (see Patent Document 1).
