　［登録動作］
　次に、身体機能管理システム１０の動作について説明する。以下では、身体機能情報の一例として、歩容情報が蓄積される例について説明する。身体機能管理システム１０は、撮像部２０によって撮像された人の歩容情報を蓄積するが、このときに、当該人が誰であるかを区別する必要がある。身体機能管理システム１０においては、人を区別するための識別情報として、顔画像(顔の部分の画像情報)、及び、歩容情報が用いられる。まず、識別情報を登録するときの動作について説明する。図３は、身体機能管理システム１０の登録動作のフローチャートである。 [Registration operation]
Next, the operation of the physical function management system 10 will be described. In the following, as an example of physical function information, an example in which gait information is accumulated will be described. The physical function management system 10 accumulates gait information of a person imaged by the imaging unit 20, and at this time, it is necessary to distinguish who the person is. In the physical function management system 10, face image (image information of a face portion) and gait information are used as identification information for distinguishing a person. First, the operation when registering the identification information will be described. FIG. 3 is a flowchart of the registration operation of the physical function management system 10.
　まず、通信端末６０は、登録のための所定の操作を登録希望者から受け付ける。この操作には、ログインＩＤ、名前、年齢、身長、性別などの情報の入力操作が含まれる。なお、これらの情報の入力方法については特に限定されず、例えば、管理装置５０がユーザインターフェースを備えるような場合には、このようなユーザインターフェースを介して入力されてもよい。このような操作が受け付けられると、通信端末６０から登録要求が送信され、送信された登録要求は管理装置５０によって受信される。 First, the communication terminal 60 accepts a predetermined operation for registration from a person who wishes to register. This operation includes an operation of inputting information such as a login ID, a name, an age, a height, and a gender. The method of inputting such information is not particularly limited, and for example, when the management device 50 includes a user interface, the information may be input via such a user interface. When such an operation is accepted, a registration request is transmitted from the communication terminal 60, and the transmitted registration request is received by the management device 50.
　管理装置５０の第二通信部５４によって登録要求が受信されると（Ｓ１１）、登録処理部５５は、登録処理を開始する（Ｓ１２）。管理装置５０の登録処理部５５は、具体的には、撮像部２０に撮像を開始させるとともに、第二通信部５４に、登録希望者に登録のための動作を指示するための指示情報を送信させる。指示情報を受信した通信端末６０の表示画面には、撮像部２０の撮像範囲を何回か歩いて往復することを指示する情報と、撮像部２０によって顔画像を撮像することを指示する情報とが表示される。 When the registration request is received by the second communication unit 54 of the management device 50 (S11), the registration processing unit 55 starts the registration process (S12). Specifically, the registration processing unit 55 of the management device 50 causes the imaging unit 20 to start imaging, and transmits instruction information for instructing the registration applicant to the operation for registration to the second communication unit 54. Let me. On the display screen of the communication terminal 60 that has received the instruction information, information instructing the image pickup unit 20 to walk back and forth several times and information instructing the image pickup unit 20 to image a face image are displayed. Is displayed.
　登録処理部５５は、登録希望者が指示通りに行動することで得られる動画に基づいて、登録用の顔画像、及び、登録用の歩容情報を生成し、上述のログインＩＤ、名前、年齢、身長、性別などの情報と、登録用の顔画像と、登録用の歩容情報とを紐づけた情報である登録済み識別情報を記憶部５３に記憶する。そして、登録処理部５５は、パスワードを発行し、パスワードを含む登録完了通知を通信端末６０に送信する。図４は、登録完了通知を受信した通信端末６０に表示される登録完了画面の一例を示す図である。なお、顔画像は、撮像部２０ではなく、通信端末６０が備える撮像部によって撮像し、登録されてもよい。 The registration processing unit 55 generates a face image for registration and gait information for registration based on a video obtained by the applicant for registration acting as instructed, and generates the above-mentioned login ID, name, and age. , Height, gender, and other information, a face image for registration, and registered identification information, which is information associated with gait information for registration, are stored in the storage unit 53. Then, the registration processing unit 55 issues a password and sends a registration completion notification including the password to the communication terminal 60. FIG. 4 is a diagram showing an example of a registration completion screen displayed on the communication terminal 60 that has received the registration completion notification. The face image may be captured and registered by the imaging unit included in the communication terminal 60 instead of the imaging unit 20.
　また、登録処理において歩容情報が登録されることは必須ではなく、例えば、登録処理においては顔画像のみが登録され、後述する他の身体機能情報の蓄積動作の際に、初回に特定された歩容情報、または、初回に特定された歩容情報に基づいて推定された身体機能情報の少なくとも一部が登録済み識別情報として使用されてもよい。 Further, it is not essential that the gait information is registered in the registration process. For example, in the registration process, only the face image is registered, and it is specified for the first time in the operation of accumulating other physical function information described later. At least a part of the gait information or the physical function information estimated based on the gait information identified at the first time may be used as the registered identification information.
　［歩容情報及び他の身体機能情報の蓄積動作］
　次に、身体機能管理システム１０の歩容情報及び他の身体機能情報の蓄積動作について説明する。図５は、身体機能管理システム１０の歩容情報及び他の身体機能情報の蓄積動作のフローチャートである。 [Accumulation of gait information and other physical function information]
Next, the gait information and other physical function information storage operations of the physical function management system 10 will be described. FIG. 5 is a flowchart of the operation of accumulating gait information and other physical function information of the physical function management system 10.
　人検知部３０によって人が検知されると（Ｓ２１）、管理装置５０の蓄積処理部５６は、撮像部２０による動画の撮像を開始する（Ｓ２２）。動画は、一時的に記憶部５３に記憶される。 When a person is detected by the person detection unit 30 (S21), the storage processing unit 56 of the management device 50 starts imaging a moving image by the imaging unit 20 (S22). The moving image is temporarily stored in the storage unit 53.
　蓄積処理部５６は、記憶部５３に記憶された動画を読み出し、当該動画に基づいて、人の歩容情報を特定する（Ｓ２３）。歩容を特定するに際して、例えば、動画に映る人の３次元骨格モデル（人の膝関節、股関節、くるぶしなどの各関節の３次元座標データ）を既存のアルゴリズムを用いて特定し、３次元骨格モデルの各骨格点の位置変化を用いて歩容情報を特定する。上述のように、歩容情報は、歩行速度、歩幅、歩隔、歩行周期、ケイデンス、左右のステップ差、歩行時の体幹の揺れ、及び、関節角度の変化量などの少なくとも１つを含めばよい。 The storage processing unit 56 reads out the moving image stored in the storage unit 53, and identifies the gait information of the person based on the moving image (S23). When specifying the gait, for example, the 3D skeleton model of the person shown in the video (3D coordinate data of each joint such as the human knee joint, hip joint, and ankle) is specified using an existing algorithm, and the 3D skeleton is specified. Gait information is specified using the position change of each skeleton point of the model. As described above, the gait information includes at least one such as walking speed, stride length, stride, walking cycle, cadence, difference between left and right steps, trunk sway during walking, and amount of change in joint angle. Just do it.
　次に、蓄積処理部５６は、動画に映る人の識別情報を特定する（Ｓ２４）。例えば、蓄積処理部５６は、既存の顔画像認識処理により、動画に映る人の顔画像を特定する。また、蓄積処理部５６は、ステップＳ２３で特定した歩容情報の少なくとも一部を識別情報として特定してもよい。例えば、動画に人の顔画像が映っていなかった場合などに、歩容情報の少なくとも一部が識別情報として使用される。動画に映る人が撮像部２０に背中を向けて歩行している場合、及び、動画に映る人がマスクを装着しているような場合には、上記顔画像認識処理によって顔画像が取得できない可能性がある。 Next, the storage processing unit 56 identifies the identification information of the person appearing in the moving image (S24). For example, the accumulation processing unit 56 identifies the face image of a person appearing in the moving image by the existing face image recognition processing. Further, the accumulation processing unit 56 may specify at least a part of the gait information specified in step S23 as identification information. For example, when a person's face image is not shown in the moving image, at least a part of the gait information is used as identification information. When the person shown in the moving image is walking with his back to the imaging unit 20, or when the person shown in the moving image is wearing a mask, the face image cannot be acquired by the above face image recognition process. There is sex.
　次に、蓄積処理部５６は、ステップＳ２３で特定された歩容情報及びステップＳ２４で特定された識別情報を紐づけて記憶部５３に一時的に記憶する（Ｓ２５）。なお、ステップＳ２５において複数人分の歩容情報が一時的に記憶される場合、複数人分の歩容情報は、類似度に応じてクラス分けされた状態で記憶されていてもよい。 Next, the storage processing unit 56 temporarily stores the gait information specified in step S23 and the identification information specified in step S24 in the storage unit 53 (S25). When the gait information for a plurality of persons is temporarily stored in step S25, the gait information for the plurality of persons may be stored in a state of being classified according to the degree of similarity.
　次に、蓄積処理部５６は、ステップＳ２５において一時的に記憶された識別情報が、登録済み識別情報と一致するか否かの判定を行う（Ｓ２６）。蓄積処理部５６は、一時的に記憶された識別情報が、登録済み識別情報と一致しないと判定した場合、一時的に記憶された歩容情報、及び、識別情報を破棄し（Ｓ２７）、動作は終了となる。 Next, the storage processing unit 56 determines whether or not the identification information temporarily stored in step S25 matches the registered identification information (S26). When the storage processing unit 56 determines that the temporarily stored identification information does not match the registered identification information, the storage processing unit 56 discards the temporarily stored gait information and the identification information (S27), and operates. Is the end.
　一方、蓄積処理部５６は、一時的に記憶された識別情報（顔画像または歩容情報の少なくとも一部）が、登録済み識別情報と一致すると判定した場合、一時的に記憶された歩容情報を、当該登録済み識別情報に紐づけて記憶（蓄積）する（Ｓ２８）。 On the other hand, when the storage processing unit 56 determines that the temporarily stored identification information (at least a part of the face image or gait information) matches the registered identification information, the temporarily stored gait information Is stored (stored) in association with the registered identification information (S28).
　そして、蓄積処理部５６は、ステップＳ２８で記憶された歩容情報に基づいて他の身体機能情報の推定を行う（Ｓ２９）。他の身体機能情報は、例えば、筋力情報または認知機能情報である。蓄積処理部５６は、例えば、動画に映る人が歩行中に前方へ踏み出す脚の膝の曲げ角度に基づいて、当該人の下肢筋力情報を推定する。また、蓄積処理部５６は、動画に映る歩行中の人が停止するときの歩行速度の変化に基づいて、当該人の下肢筋力情報を推定する。身体機能情報としては、その他に、歩行中の左右のバランスなどが例示される。筋力と同じように、認知機能に関しても、例えば歩行中の脚の膝の曲げ角度の衰えや歩行中の左右バランスの劣化をもとに推定することが可能である。また、蓄積処理部５６は、このように推定した他の身体機能情報を、上記登録済み識別情報に紐づけて記憶する（Ｓ３０）。 Then, the accumulation processing unit 56 estimates other physical function information based on the gait information stored in step S28 (S29). Other physical function information is, for example, muscle strength information or cognitive function information. The accumulation processing unit 56 estimates the lower limb muscle strength information of the person, for example, based on the bending angle of the knee of the leg that the person shown in the moving image steps forward while walking. In addition, the accumulation processing unit 56 estimates the lower limb muscle strength information of the walking person shown in the moving image based on the change in the walking speed when the walking person stops. Other examples of physical function information include left-right balance during walking. Similar to muscular strength, cognitive function can be estimated based on, for example, a decrease in the bending angle of the knee of the leg during walking and a deterioration in the left-right balance during walking. Further, the accumulation processing unit 56 stores the other physical function information estimated in this way in association with the registered identification information (S30).
　このように、身体機能管理システム１０は、特定される識別情報が、登録済み識別情報と一致する場合には、歩容情報を登録済み識別情報と紐づけて記憶し、歩容情報に基づいて、他の身体機能を推定する。これにより、登録済みの人の身体機能情報を選択的に記憶部５３に蓄積することができる。また、身体機能容管理システム１０は、識別情報と一致した人の歩容情報に基づいて認知症機能低下や筋力低下などの他の身体機能情報を推定し、記憶部５３に蓄積することもできる。なお、複数種類の身体機能情報が蓄積されることは必須ではなく、身体機能管理システム１０は、少なくとも一種類の身体機能情報を蓄積すればよい。 As described above, when the identified identification information matches the registered identification information, the physical function management system 10 stores the gait information in association with the registered identification information, and based on the gait information. , Estimate other physical functions. As a result, the registered person's physical function information can be selectively stored in the storage unit 53. In addition, the physical function management system 10 can estimate other physical function information such as dementia function decline and muscle weakness based on the gait information of the person who matches the identification information, and can store it in the storage unit 53. .. It is not essential that a plurality of types of physical function information are accumulated, and the physical function management system 10 may accumulate at least one type of physical function information.
　なお、上記図５のフローチャートにおいては、動画は、一時的に記憶部５３に記憶され、蓄積処理部５６は、記憶部５３に記憶された動画を読み出し、当該動画に基づいて人の歩容情報を特定し、特定した歩容情報に基づいて他の身体機能情報の推定を行った。しかしながら、他の身体機能情報は、歩容情報を特定せずに動画から直接推定されてもよい。この場合、蓄積処理部５６は、識別情報と動画が紐付けされているために、記憶部５３への一時的な記憶が終了してから他の身体機能情報を推定することができ、推定に必要なコンピュータなどの計算処理時間を十分にかけて精度のよい推定を行うことができる。 In the flowchart of FIG. 5, the moving image is temporarily stored in the storage unit 53, the storage processing unit 56 reads out the moving image stored in the storage unit 53, and the gait information of a person is based on the moving image. Was identified, and other physical function information was estimated based on the identified gait information. However, other physical function information may be estimated directly from the moving image without specifying the gait information. In this case, since the storage processing unit 56 is associated with the identification information and the moving image, other physical function information can be estimated after the temporary storage in the storage unit 53 is completed, and the estimation can be performed. It is possible to make an accurate estimation by spending sufficient calculation processing time on a necessary computer or the like.
　［身体機能情報の配信動作］
　次に、身体機能管理システム１０の身体機能情報の配信動作について説明する。図６は、身体機能管理システム１０の身体機能情報の配信動作のフローチャートである。 [Distribution of physical function information]
Next, the operation of distributing the physical function information of the physical function management system 10 will be described. FIG. 6 is a flowchart of the physical function information distribution operation of the physical function management system 10.
　まず、通信端末６０は、身体機能情報の配信を受けるための所定の操作を登録済みユーザから受け付ける。この操作には、ログインＩＤ、及び、パスワードの入力操作が含まれる。なお、これらの情報の入力方法については特に限定されない。このような操作が受け付けられると、通信端末６０から配信要求が送信され、送信された配信要求は管理装置５０によって受信される。 First, the communication terminal 60 receives a predetermined operation for receiving the distribution of the physical function information from the registered user. This operation includes a login ID and a password input operation. The method of inputting such information is not particularly limited. When such an operation is accepted, a distribution request is transmitted from the communication terminal 60, and the transmitted distribution request is received by the management device 50.
　管理装置５０の第二通信部５４によって配信要求が受信されると（Ｓ３１）、配信処理部５７は、配信処理を開始する（Ｓ３２）。配信処理部５７は、配信要求に含まれるログインＩＤ及びパスワードが正しいかを判定し、正しい場合には、これらのログインＩＤ（つまり、登録済み識別情報）に紐づけられた身体機能情報を、記憶部５３を参照することにより特定する。 When the distribution request is received by the second communication unit 54 of the management device 50 (S31), the distribution processing unit 57 starts the distribution process (S32). The distribution processing unit 57 determines whether the login ID and password included in the distribution request are correct, and if they are correct, stores the physical function information associated with these login IDs (that is, the registered identification information). It is specified by referring to the part 53.
　配信処理部５７は、第二通信部５４に、特定した身体機能情報を通知するための通知情報を通信端末６０へ送信させる。図７は、このような通知情報を受信した通信端末６０に表示される表示画面の一例を示す図である。 The distribution processing unit 57 causes the second communication unit 54 to transmit the notification information for notifying the specified physical function information to the communication terminal 60. FIG. 7 is a diagram showing an example of a display screen displayed on the communication terminal 60 that has received such notification information.

The identification information registered by the registration operation can also be used as authentication information for unlocking the door 41. FIG. 8 is a diagram showing an outline of the authentication operation of the physical function management system 10. FIG. 9 is a flowchart of the authentication operation of the physical function management system 10.
　図８に示されるように、実施の形態では、撮像部２０の１つ、及び、人検知部３０は、ドアホンによって備えられている。ドアホンに人が近づくと、人検知部３０はこれを検知する（Ｓ４１）。管理装置５０の認証処理部５８は、撮像部２０による動画の撮像を開始する（Ｓ４２）。動画は、一時的に記憶部５３に記憶される。 As shown in FIG. 8, in the embodiment, one of the image pickup units 20 and the person detection unit 30 are provided by a door phone. When a person approaches the door phone, the person detection unit 30 detects this (S41). The authentication processing unit 58 of the management device 50 starts imaging a moving image by the imaging unit 20 (S42). The moving image is temporarily stored in the storage unit 53.
　次に、認証処理部５８は、記憶部５３に記憶された動画を対象として顔画像認識処理を行うことにより動画に映る人の顔画像を特定し（Ｓ４３）、特定した顔画像が、登録済み識別情報に含まれる顔画像と一致するか否かの判定を行う（Ｓ４４）。認証処理部５８によって、特定した顔画像が登録済み識別情報に含まれる顔画像と一致しないと判定された場合（Ｓ４４でＮｏ）、動作は終了となる。 Next, the authentication processing unit 58 identifies the face image of the person appearing in the moving image by performing the face image recognition processing on the moving image stored in the storage unit 53 (S43), and the specified face image is registered. It is determined whether or not the image matches the face image included in the identification information (S44). When the authentication processing unit 58 determines that the specified face image does not match the face image included in the registered identification information (No in S44), the operation ends.
　一方、認証処理部５８は、特定した顔画像が、登録済み識別情報に含まれる顔画像と一致すると判定した場合（Ｓ４４でＹｅｓ）、ドア４１のロックを解除するための解除信号を、第一通信部５１に錠前装置４０へ出力させる（Ｓ４５）。これにより、ドア４１のロックが解除される。 On the other hand, when the authentication processing unit 58 determines that the specified face image matches the face image included in the registered identification information (Yes in S44), the authentication processing unit 58 first issues a release signal for unlocking the door 41. The communication unit 51 is made to output to the lock device 40 (S45). As a result, the door 41 is unlocked.
　このように、身体機能管理システム１０は、上記登録動作によって登録された識別情報を、ドア４１のロックを解除するための認証情報として使用することもできる。なお、ステップＳ４３及びステップＳ４４では、顔画像に代えて、身体機能情報に基づく認証処理が行われてもよい。 As described above, the physical function management system 10 can also use the identification information registered by the above registration operation as the authentication information for unlocking the door 41. In steps S43 and S44, authentication processing based on physical function information may be performed instead of the face image.
