　以下、図３～図５を参照して、スマートフォン４が利用者の操作に基づく要求環境設定を空調制御装置２に送信する処理の流れを説明する。 (Process flow of smartphone)
Drawing 3 is a flow chart which shows an example of processing of a smart phone concerning a 1st embodiment.
FIG. 4 is a view showing an example of a landmark image according to the first embodiment.
FIG. 5 is a diagram showing an example of transmission information according to the first embodiment.
Hereinafter, with reference to FIGS. 3 to 5, the flow of processing in which the smartphone 4 transmits the required environment setting based on the user's operation to the air conditioning control device 2 will be described.
　まず、スマートフォン４のランドマーク画像取得部４００は、カメラ４３により撮影された画像からランドマークＬを切り出した、ランドマーク画像を取得する（ステップＳ１０）。
　図１に示すように、ランドマークＬは、カメラ４３により撮影された画像内における背景とランドマークＬとを切り分け可能なように、ランドマークＬを検出するための検出パターンＦａ～Ｆｃを含んでいる。なお、図１の例では、ランドマークＬは三つの検出パターンＦａ～Ｆｃを有しているが、他の実施形態では、ランドマークＬを検出可能であれば少なくとも一つ検出パターンを有していればよく、三つ未満、または四つ以上の検出パターンを有していてもよい。
　ランドマーク画像取得部４００は、検出パターンＦａ～Ｆｃを参照することにより、どの位置、どの角度から撮影された画像であっても、ランドマークＬのみを切り出したランドマーク画像を取得することができる。 First, the landmark image acquisition unit 400 of the smartphone 4 acquires a landmark image obtained by extracting the landmark L from the image captured by the camera 43 (step S10).
As shown in FIG. 1, the landmark L includes detection patterns Fa to Fc for detecting the landmark L so that the background and the landmark L in the image captured by the camera 43 can be separated. There is. In the example of FIG. 1, the landmark L has three detection patterns Fa to Fc, but in another embodiment, it has at least one detection pattern as long as the landmark L can be detected. And may have less than three, or four or more detection patterns.
The landmark image acquisition unit 400 can acquire a landmark image in which only the landmark L is cut out by referring to the detection patterns Fa to Fc, regardless of the position and the angle from which the image is captured. .
　また、図４に示すように、利用者は、自身が位置する場所（利用者位置）から、スマートフォン４のカメラ４３によりランドマークＬを撮影する。そうすると、ランドマーク画像のサイズ及び形状（傾き等）は、利用者位置に応じて変形する。
　例えば、ランドマーク画像のサイズは、ランドマークＬの設置位置（ランドマーク位置Ｄ）から離れるほど、ランドマークＬの実際のサイズ（図１の縦幅Ｈ、横幅Ｗ）よりも小さくなる。
　また、ランドマーク画像の形状は、利用者位置がランドマークＬの正面（図４の位置Ｐａ）から離れるほど変形量が大きくなる。図４の例では、ランドマーク画像は、利用者位置がランドマークＬの正面から離れるほど、利用者位置からランドマークＬを見たときの仰俯角θが小さくなるように変形する。
　更に、ランドマーク画像の形状は、利用者位置の高さに応じても変化する。例えば、図４に示すように、ランドマークＬの正面の位置、且つ、ランドマークＬと同じ高さ（位置Ｐａ１）で撮影した場合、ランドマーク画像の上辺と下辺とは略同一の長さとなる。一方、ランドマークＬよりも高い位置（位置Ｐａ２）から撮影した場合、ランドマーク画像は上底が下底よりも長い台形状の形状を有し、ランドマークＬよりも低い位置（位置Ｐａ３）から撮影した場合、ランドマーク画像は上底よりも下底が長い台形状の形状を有する。
　このように、ランドマーク画像は、利用者位置Ｐａ～Ｐｃに応じたサイズ及び形状の変形量を検出可能な画像データである。即ち、ランドマーク画像のサイズ及び形状に基づき、利用者位置（ランドマークＬを撮影した位置）の三次元的な位置を検出することが可能である。また、ランドマーク画像は、例えばＥＸＩＦ（Exchangeable image file format）等のファイルフォーマットで記録され、ランドマークＬを撮影した際の焦点距離等、撮影時の条件を特定可能な情報を含んでいる。これにより、利用者がズームしてランドマークＬの撮影を行った場合であっても、焦点距離等に基づいて利用者位置を補正することが可能である。
　また、ランドマーク画像取得部４００は、ランドマーク画像を取得するとともに、既知の二次元コード処理技術を用いて、ランドマークＬ（二次元コード）に予め記録された情報を読み取るようにしてもよい。例えば、ランドマークＬには、ランドマークＬを特定可能なランドマークＩＤ、要求環境設定の入力フォームへアクセスするためのＵＲＬ等が含まれているものとする。この場合、ランドマーク画像取得部４００は、読み取ったＵＲＬに基づいて、表示部４２に入力フォームを表示させる。 In addition, as shown in FIG. 4, the user shoots the landmark L with the camera 43 of the smartphone 4 from the place where the user is located (user position). Then, the size and shape (inclination, etc.) of the landmark image are deformed according to the user position.
For example, the size of the landmark image becomes smaller than the actual size (vertical width H, horizontal width W in FIG. 1) of the landmark L as it goes away from the installation position of the landmark L (landmark position D).
In the shape of the landmark image, the amount of deformation increases as the user position moves away from the front of the landmark L (position Pa in FIG. 4). In the example of FIG. 4, the landmark image is deformed such that the supine angle θ when viewing the landmark L from the user position decreases as the user position moves away from the front of the landmark L.
Furthermore, the shape of the landmark image also changes according to the height of the user position. For example, as shown in FIG. 4, when photographing at the position in front of the landmark L and at the same height (position Pa1) as the landmark L, the upper side and the lower side of the landmark image have substantially the same length. . On the other hand, when photographed from a position (position Pa2) higher than the landmark L, the landmark image has a trapezoidal shape in which the upper base is longer than the lower base and from a lower position (position Pa3) than the landmark L When photographed, the landmark image has a trapezoidal shape in which the lower base is longer than the upper base.
Thus, the landmark image is image data capable of detecting the amount of deformation of the size and shape according to the user positions Pa to Pc. That is, it is possible to detect the three-dimensional position of the user position (the position where the landmark L is photographed) based on the size and shape of the landmark image. Further, the landmark image is recorded in a file format such as EXIF (Exchangeable image file format), for example, and includes information capable of specifying conditions at the time of shooting such as a focal length at the time of shooting the landmark L. Thereby, even when the user zooms in and shoots the landmark L, it is possible to correct the user position based on the focal length and the like.
Further, the landmark image acquisition unit 400 may acquire the landmark image and read information recorded in advance in the landmark L (two-dimensional code) using a known two-dimensional code processing technology. . For example, it is assumed that the landmark L includes a landmark ID that can specify the landmark L, a URL for accessing the input form of the request environment setting, and the like. In this case, the landmark image acquisition unit 400 causes the display unit 42 to display an input form based on the read URL.
　次に、スマートフォン４の要求環境設定受付部４０１は、利用者から操作部４１を介して入力された要求環境設定（設定温度、設定湿度、設定風量等）を受け付ける（ステップＳ１１）。 Next, the request environment setting reception unit 401 of the smartphone 4 receives the request environment settings (set temperature, set humidity, set air volume, and the like) input from the user via the operation unit 41 (step S11).
　次に、スマートフォン４の要求環境設定受付部４０１は、ランドマーク画像と要求環境設定とを含む送信情報を、通信Ｉ／Ｆ４４を介して空調制御装置２へ送信する（ステップＳ１２）。
　送信情報は、図５に示すように、スマートフォン４を所持する利用者を特定可能な利用者ＩＤ（「０００１」）、ステップＳ１０において取得されたランドマーク画像及びランドマークＩＤ（「０００Ａ」）、ステップＳ１１において取得された要求環境設定（「設定温度：＊＊℃」、「設定湿度：＊＊％」、「設定風量：小」、…）等を関連付けた情報である。
　なお、利用者ＩＤは、スマートフォン４別に固有の利用者ＩＤが予め設定されていてもよいし、スマートフォン４と空調制御装置２とが通信を開始する際に異なる利用者ＩＤが自動的に割り振られるようにしてもよい。 Next, the request environment setting reception unit 401 of the smartphone 4 transmits the transmission information including the landmark image and the request environment setting to the air conditioning control device 2 via the communication I / F 44 (step S12).
The transmission information is, as shown in FIG. 5, a user ID ("0001") that can identify the user who holds the smartphone 4, the landmark image and the landmark ID ("000A") acquired in step S10, It is information in which the required environment settings (“set temperature: ** ° C.”, “set humidity: **%”, “set air volume: small”, etc.) and the like acquired in step S11 are associated with one another.
In addition, a unique user ID may be set in advance for each smartphone 4 for the user ID, and different user IDs are automatically assigned when the smartphone 4 and the air conditioning control device 2 start communication. You may do so.
　スマートフォン４は、利用者がカメラ４３によりランドマークＬを撮影する度に、上述の各処理を実行する。
　なお、利用者は、現在の利用者位置から移動しない状態で、要求環境設定を複数回変更する場合がある。この場合、スマートフォン４は、ステップＳ１０において、過去に撮影されたランドマーク画像を記憶部４５から読み出す（取得する）ようにしてもよい。 The smartphone 4 executes each process described above each time the user shoots the landmark L with the camera 43.
The user may change the required environment setting multiple times without moving from the current user position. In this case, in step S10, the smartphone 4 may read (acquire) a landmark image captured in the past from the storage unit 45.

The flow of processing for controlling the air conditioning indoor unit 3 based on the transmission information received from the smartphone 4 by the air conditioning control device 2 will be described below with reference to FIGS. 6 to 11.
　まず、空調制御装置２の位置推定部２００は、通信Ｉ／Ｆ２１を介してスマートフォン４から送信情報を受信する（ステップＳ２０）。 First, the position estimation unit 200 of the air conditioning control device 2 receives the transmission information from the smartphone 4 via the communication I / F 21 (step S20).
　次に、空調制御装置２の位置推定部２００は、スマートフォン４から受信した送信情報に含まれるランドマーク画像に基づいて、当該送信情報の送信者の位置（利用者位置）を推定する（ステップＳ２１）。
　具体的には、位置推定部２００は、図７に示す利用者位置を推定するための各処理を実行する。 Next, the position estimation unit 200 of the air conditioning control device 2 estimates the position (user position) of the transmitter of the transmission information based on the landmark image included in the transmission information received from the smartphone 4 (step S21) ).
Specifically, position estimation unit 200 executes each process for estimating the user position shown in FIG. 7.
　図７に示すように、位置推定部２００は、ランドマークＬを特定可能なランドマークＩＤを取得する（ステップＳ２１０）。
　位置推定部２００は、送信情報にランドマークＩＤが含まれている場合、送信情報からランドマークＩＤを取得する。
　なお、位置推定部２００は、既存の二次元コード処理技術を利用して、ランドマーク画像に含まれるランドマークＬ（二次元コード）からランドマークＩＤを読み取って取得するようにしてもよい。この場合、送信情報にはランドマークＩＤが含まれていなくてもよい。 As shown in FIG. 7, the position estimation unit 200 acquires a landmark ID that can specify the landmark L (step S <b> 210).
When the transmission information includes the landmark ID, the position estimation unit 200 acquires the landmark ID from the transmission information.
The position estimation unit 200 may read and acquire the landmark ID from the landmark L (two-dimensional code) included in the landmark image using the existing two-dimensional code processing technology. In this case, the transmission information may not include the landmark ID.
　次に、位置推定部２００は、ランドマークＩＤと関連付けられたランドマーク情報を、記憶部４５から取得する（ステップＳ２１１）。
　図８に示すように、本実施形態に係るランドマーク情報は、「ランドマークＩＤ」と、「ランドマーク位置」と、「画像パターン」等を含む。
　ランドマーク位置は、空間内においてランドマークＬが設置された位置（図９のランドマーク位置Ｄ）を示す座標情報（「ｘＤａ，ｙＤａ，ｚＤａ」、「ｘＤｂ，ｙＤｂ，ｚＤｂ」、…）である。
　画像パターンは、ランドマーク位置Ｄを起点とした複数の異なる相対位置と、相対位置それぞれから見たときのランドマークＬのサイズ及び形状を識別可能なサンプル画像とを関連付けた情報である。 Next, the position estimation unit 200 acquires landmark information associated with the landmark ID from the storage unit 45 (step S211).
As shown in FIG. 8, the landmark information according to the present embodiment includes “landmark ID”, “landmark position”, “image pattern” and the like.
The landmark position is coordinate information (“x Da , y Da , z Da ”, “x Db , y Db , z Db ”) indicating the position (landmark position D in FIG. 9) at which the landmark L is installed in the space. ", ...).
The image pattern is information in which a plurality of different relative positions starting from the landmark position D are associated with a sample image that can identify the size and shape of the landmark L when viewed from each of the relative positions.
　次に、位置推定部２００は、ランドマーク画像に既知の画像処理を施すことにより、ランドマーク位置Ｄを起点とする利用者の相対位置を推定する（ステップＳ２１２）。
　例えば、図９に示すように、利用者が位置ＰｃからランドマークＬを撮影したとする。
　このとき、位置推定部２００は、ランドマーク画像と、ランドマーク情報に含まれる画像パターンとにパターンマッチング処理を施して最尤推定を行うことにより、ランドマーク画像に最も近似すると推定されるサンプル画像を抽出する。そして、位置推定部２００は、抽出したサンプル画像と関連付けられた相対位置（ランドマーク位置Ｄからの距離ｒ、方位角ψ、仰俯角θ）を、利用者の相対位置として推定する。
　なお、位置推定部２００は、ランドマーク画像のサイズ（例えばランドマークＬの縦幅Ｈ及び横幅Ｗを基準とした比率）及び形状の変形量（例えばランドマーク画像の傾き等の変形量）から、ランドマーク位置Ｄからの距離ｒ、方位角ψ、仰俯角θを計算することにより、利用者の相対位置を推定してもよい。この場合、ランドマーク情報は、画像パターンを含んでいなくてもよい。 Next, the position estimation unit 200 estimates the relative position of the user starting from the landmark position D by performing known image processing on the landmark image (step S212).
For example, as shown in FIG. 9, it is assumed that the user photographs the landmark L from the position Pc.
At this time, the position estimation unit 200 performs pattern matching processing on the landmark image and the image pattern included in the landmark information to perform maximum likelihood estimation, thereby estimating the sample image most approximate to the landmark image. Extract Then, the position estimation unit 200 estimates the relative position (distance r from the landmark position D, azimuth angle ψ, supine angle θ) associated with the extracted sample image as the relative position of the user.
The position estimation unit 200 uses the size of the landmark image (for example, the ratio based on the vertical width H and the horizontal width W of the landmark L) and the deformation amount of the shape (for example, deformation amount such as inclination of the landmark image). The relative position of the user may be estimated by calculating the distance r from the landmark position D, the azimuth angle ψ, and the supine angle θ. In this case, the landmark information may not include the image pattern.
　次に、位置推定部２００は、ステップＳ２１２において推定したランドマーク位置Ｄからの相対位置に基づいて、利用者位置（「ｘｐｃ，ｙｐｃ，ｚｐｃ」）を推定する（ステップＳ２１３）。
　そして、位置推定部２００が利用者位置を推定する各処理を完了すると、空調制御装置２は、図６のステップＳ２１を終了して、次のステップＳ２２へ進む。 Next, the position estimation unit 200 estimates the user position (“x pc , y pc , z pc ”) based on the relative position from the landmark position D estimated in step S 212 (step S 213).
Then, when the position estimation unit 200 completes each process of estimating the user position, the air conditioning control device 2 ends step S21 of FIG. 6 and proceeds to the next step S22.
　次に、図６に示すように、空調制御装置２の位置取得部２０１は、位置推定部２００が推定した利用者位置を取得する（ステップＳ２２）。 Next, as shown in FIG. 6, the position acquisition unit 201 of the air conditioning control device 2 acquires the user position estimated by the position estimation unit 200 (step S22).
　次に、要求環境取得部２０２は、受信した送信情報から要求環境設定を取得する（ステップＳ２３）。 Next, the required environment acquisition unit 202 acquires required environment settings from the received transmission information (step S23).
　そして、要求環境取得部２０２は、要求環境設定と、位置取得部２０１が取得した利用者位置とを関連付けて、利用者別情報（図１０）として記憶部２２に追加して記憶する（ステップＳ２４）。
　利用者別情報は、図１０に示すように、送信情報に含まれる利用者ＩＤ（「０００１」）及び要求環境設定（「設定温度：＊＊℃」、「設定湿度：＊＊％」、「設定風量：小」、…）と、位置推定部２００が推定した利用者位置（「ｘｐｃ，ｙｐｃ，ｚｐｃ」）とを関連付けた情報を、利用者別に記憶するテーブルである。 Then, the required environment acquisition unit 202 associates the required environment setting with the user position acquired by the position acquisition unit 201, adds it to the storage unit 22 as user-specific information (FIG. 10), and stores it (step S24). ).
As shown in FIG. 10, the user-specific information includes the user ID (“0001”) included in the transmission information and the required environment setting (“set temperature: ** ° C.”, “set humidity: **%”, "Set air volume: small", ...) is a table for storing, for each user, information in which the user position ("x pc , y pc , z pc ") estimated by the position estimation unit 200 is associated.
　次に、室内機制御部２０３は、利用者別情報に含まれる利用者位置及び要求環境設定に基づいて、可能な限り利用者の要求を満たすように空調用室内機３の制御を行う（ステップＳ２５）。
　具体的には、室内機制御部２０３は、図１１に示す空調の最適化を行うための各処理を実行する。 Next, the indoor unit control unit 203 controls the air conditioning indoor unit 3 so as to satisfy the user request as much as possible based on the user position and the request environment setting included in the user-specific information (Step S25).
Specifically, the indoor unit control unit 203 executes each process for optimizing the air conditioning shown in FIG.
　図１１に示すように、室内機制御部２０３は、目的関数Ｊを最小化するための制御パラメータ（ａ１、ａ２、ａ３、ａ４、・・）を特定する（ステップＳ２５０）。ここで、制御パラメータとは、空調用室内機３を所望の状態とさせるための直接的な指令値であって、例えば、ファン３０の回転数、ルーバー３１の傾斜角度などである。
　目的関数Ｊは、例えば式（１）のように規定される。 As shown in FIG. 11, the indoor unit control unit 203 specifies control parameters (a1, a2, a3, a4,...) For minimizing the objective function J (step S250). Here, the control parameter is a direct command value for bringing the air conditioning indoor unit 3 into a desired state, and is, for example, the number of rotations of the fan 30, the inclination angle of the louver 31, or the like.
The objective function J is defined, for example, as in equation (1).

　式（１）に示すベクトルｘ（ｉ）は、利用者ｉ（ｉ＝１，２，・・，Ｎ）が存在する位置における実際の温度、湿度、風量等を示すベクトル量である。ベクトルｘ（ｉ）は、Ｍ個の要素（ｘ（ｉ）１，ｘ（ｉ）２，・・，ｘ（ｉ）Ｍ）からなり、各要素（ｘ（ｉ）１，ｘ（ｉ）２，・・，ｘ（ｉ）Ｍ）は、利用者ｉが存在する位置における実際の温度、湿度、風量等の値（スカラー量）を示している。また、式（１）に示すように、ベクトルｘ（ｉ）は、空調用室内機３の制御パラメータ（ａ１、ａ２、ａ３、ａ４、・・）を入力変数とする関数Ｆによって一意に定まる。
　また、ベクトルｘ＊（ｉ）は、利用者ｉが希望する温度、湿度、風量等を示すベクトル量である。ベクトルｘ＊（ｉ）は、Ｍ個の要素（ｘ＊（ｉ）１，ｘ＊（ｉ）２，・・，ｘ＊（ｉ）Ｍ）からなり、各要素（ｘ＊（ｉ）１，ｘ＊（ｉ）２，・・，ｘ＊（ｉ）Ｍ）は、利用者ｉが希望する温度、湿度、風量等を示している。より具体的には、各要素（ｘ＊（ｉ）１，ｘ＊（ｉ）２，・・，ｘ＊（ｉ）Ｍ）は、利用者別情報（図７）に示される設定温度、設定湿度、設定風量等である。
　式（１）に示すように、目的関数Ｊは、まず、ベクトルｘ（ｉ）の第ｋ要素（ｋ＝１，・・，Ｍ）ごとに誤差率（（ｘ（ｉ）ｋ－ｘ＊（ｉ）ｋ）／ｘ＊（ｉ）ｋ）を求め、全要素で足し合わせる。そして、目的関数Ｊは、利用者ｉごとに求められた上記誤差率の総和を、更に全利用者で足し合わせることによって導出される。
　“Ｍ”は、ベクトルｘ（ｉ）、ベクトルｘ＊（ｉ）を構成する要素の数であって、温度、湿度、風量など、利用者が設定の対象とすべき物理量の総数である。
　“Ｎ”は、空調用室内機３が設置された空間内に存在する利用者の人数であって、より具体的には、超音波を通じて検知されたスマートフォン４の台数（利用者ＩＤの種類の数）である。
　“Ｗｐ（ｉ）”は、利用者別に別途規定された重み付け係数であり、一般的な運用では、全て“１”（等しい値）とされる。しかし、例えば、高齢の利用者や重役の利用者の要求を重視する運用を行う場合などにおいては、利用者（ｉ）ごとの重み付け係数を変化させてもよい。
　また、目的関数Ｊの最小値を特定する方法は、良く知られている探索アルゴリズムに基づくものであってもよい。関数Ｆは、例えば、気流、放射に基づく空間内の温度分布、湿度分布、風量分布の物理シミュレーションに基づくものであってもよい。 The vector x (i) shown in the equation (1) is a vector quantity indicating the actual temperature, humidity, air volume and the like at the position where the user i (i = 1, 2,..., N) exists. The vector x (i) consists of M elements (x (i) 1 , x (i) 2 ,..., X (i) M ), and each element (x (i) 1 , x (i) 2 ,..., X (i) M ) indicate values (scalar amounts) such as actual temperature, humidity, and air volume at the position where the user i exists. Further, as shown in the equation (1), the vector x (i) is uniquely determined by the function F having the control parameters (a1, a2, a3, a4,...) Of the air conditioning indoor unit 3 as input variables.
Further, vector x * (i) is a vector quantity indicating the temperature, humidity, air volume, etc. desired by the user i. The vector x * (i) consists of M elements (x * (i) 1 , x * (i) 2 , ..., x * (i) M ), and each element (x * (i) 1 , x * (i) 2 ... x * (i) M indicates the temperature, humidity, air flow, etc. desired by the user i. More specifically, each element (x * (i) 1 , x * (i) 2 , ..., x * (i) M ) is the setting temperature shown in the user-specific information (FIG. 7), setting Humidity, set air volume, etc.
As shown in the equation (1), the objective function J first generates an error rate ((x (i) k −x * ( K ) for each kth element (k = 1,..., M) of the vector x (i) i) Find k ) / x * (i) k ) and add up all the elements. Then, the objective function J is derived by further adding up the sum of the above error rates obtained for each user i by all the users.
“M” is the number of elements constituting the vector x (i) and the vector x * (i), and is the total number of physical quantities such as temperature, humidity, and air volume that the user should set.
“N” is the number of users present in the space where the air conditioning indoor unit 3 is installed, and more specifically, the number of smartphones 4 detected through ultrasonic waves (type of user ID Number).
“Wp (i)” is a weighting coefficient separately specified for each user, and in general operation, it is all “1” (equal value). However, for example, in the case of an operation where importance is placed on the requirements of elderly users and users of executive officers, the weighting coefficient for each user (i) may be changed.
Also, the method of identifying the minimum value of the objective function J may be based on a well-known search algorithm. The function F may be based on physical simulation of air flow, temperature distribution in space based on radiation, humidity distribution, air volume distribution, for example.
　目的関数Ｊを最小化する制御パラメータを特定すると、室内機制御部２０３は、特定した制御パラメータを指令値として空調用室内機３に送信し、制御する（ステップＳ２５１）。 When the control parameter that minimizes the objective function J is specified, the indoor unit control unit 203 transmits the specified control parameter as a command value to the air conditioning indoor unit 3 and performs control (step S251).
　このように、空調制御装置２は、スマートフォン４から送信情報を受信するたびに、上述の各処理を繰り返し実行する。 As described above, each time the air conditioning control device 2 receives the transmission information from the smartphone 4, the air conditioning control device 2 repeatedly executes the above-described processes.
（作用効果）
　以上のように、本実施形態に係る空調制御装置２は、ランドマークＬが撮影されたランドマーク画像を分析することにより推定される利用者位置を取得する位置取得部２０１と、利用者の要求環境設定を取得する要求環境取得部２０２と、利用者位置及び要求環境設定に基づいて、空調用室内機３の制御を行う室内機制御部２０３と、を備える。
　また、本実施形態に係る空調制御装置２は、ランドマーク画像を分析し利用者位置を推定する位置推定部２００をさらに備える。位置取得部２０１は、前記位置推定部が推定した前記利用者位置を取得する。
　従来の技術では、ランドマークが設置された場所（利用者の位置）とランドマークに記憶された位置情報とは一対一で対応付けられているので、ランドマークが設置された場所から離れた位置に利用者がいる場合、当該利用者の位置を認識することが困難であった。したがって、従来の技術では、ある空間に複数の利用者が存在する場合、利用者の数に応じて多数のランドマークを設置する必要があった。また、ランドマークの設置位置を変えるごとに、ランドマークとランドマーク位置との関連付けを更新する必要がある。この結果、当該空間における利用者数（ランドマーク数）が多いほどランドマークの管理に係る負荷が増大する可能性があった。
　しかしながら、本実施形態に係る空調制御装置２によれば、位置推定部２００は、ランドマークＬから離れた位置に利用者がいる場合であっても、当該利用者が撮影したランドマーク画像を分析して利用者位置を推定することができる。
　これにより、一つのランドマークＬで複数の異なる利用者位置を割り出すことができるので、ランドマークＬの設置数を減らすことができ、また、ランドマーク情報の管理に係る負荷を削減することができる。 (Action effect)
As described above, the air conditioning control device 2 according to the present embodiment includes the position acquisition unit 201 for acquiring the user position estimated by analyzing the landmark image in which the landmark L is captured, and the user's request. The required environment acquisition part 202 which acquires environment setting, and the indoor unit control part 203 which controls the indoor unit 3 for air conditioning based on a user position and a required environment setting are provided.
In addition, the air conditioning control device 2 according to the present embodiment further includes a position estimation unit 200 that analyzes the landmark image and estimates the user position. The position acquisition unit 201 acquires the user position estimated by the position estimation unit.
In the prior art, the location where the landmark is installed (the position of the user) is associated with the position information stored in the landmark on a one-to-one basis, so the location away from the location where the landmark is installed It is difficult to recognize the position of the user when the user is in the Therefore, in the prior art, when there are a plurality of users in a certain space, it is necessary to set a large number of landmarks according to the number of users. In addition, it is necessary to update the association between the landmark and the position of the landmark every time the installation position of the landmark is changed. As a result, as the number of users (the number of landmarks) in the space increases, there is a possibility that the load for managing landmarks may increase.
However, according to the air conditioning control device 2 according to the present embodiment, even if the user is at a position away from the landmark L, the position estimation unit 200 analyzes the landmark image captured by the user. User position can be estimated.
Thereby, since a plurality of different user positions can be determined by one landmark L, the number of landmarks L installed can be reduced, and the load associated with management of landmark information can be reduced. .
　また、室内機制御部２０３は、複数の利用者が要求するそれぞれの要求環境設定に応じて、空調用室内機３の制御を行う。
　このようにすることで、室内機制御部２０３は、同じ空間内に異なる要求（温度、湿度、風量等の要求）を有する利用者が複数存在したとしても、利用者それぞれの要求を可能な限り満たした環境となるように、空調用室内機３を制御することができる。 Further, the indoor unit control unit 203 controls the air conditioning indoor unit 3 in accordance with each required environment setting required by a plurality of users.
By doing this, even if there are multiple users having different requests (requests of temperature, humidity, air volume, etc.) in the same space, the indoor unit control unit 203 can make the respective requests of the users as much as possible. The air conditioning indoor unit 3 can be controlled so as to provide a filled environment.

　第１の実施形態と共通の構成要素には同一の符号を付して詳細説明を省略する。 Second Embodiment
Next, an air conditioning system 1 according to a second embodiment of the present invention will be described with reference to FIGS. 12 to 13.
The same components as in the first embodiment will be assigned the same reference numerals and detailed explanations thereof will be omitted.
　図１２は、第２の実施形態に係る空調システムの機能構成の一例を示す図である。
　図１２に示すように、本実施形態では、スマートフォン４のＣＰＵ４０が、利用者位置を推定する位置推定部４０２を有している点において、第１の実施形態とは異なっている。
　なお、本実施形態では、空調制御装置２のＣＰＵ２０は、位置推定部２００が省略されている。 FIG. 12 is a diagram showing an example of a functional configuration of the air conditioning system according to the second embodiment.
As shown in FIG. 12, the present embodiment is different from the first embodiment in that the CPU 40 of the smartphone 4 includes a position estimation unit 402 that estimates a user position.
In the present embodiment, the position estimation unit 200 is omitted from the CPU 20 of the air conditioning control device 2.

User position of the user who
At this time, it is assumed that landmark information (FIG. 8) is stored in advance in the storage unit 45 of the smartphone 4.

　図１３に示すように、本実施形態に係る送信情報は、利用者ＩＤ（「０００１」）、利用者が操作部４１を介して入力した要求環境設定（「設定温度：＊＊℃」、「設定湿度：＊＊％」、「設定風量：小」、…）、位置推定部４０２が推定した利用者位置（「ｘｐｃ，ｙｐｃ，ｚｐｃ」）等を関連付けた情報である。
　本実施形態では、スマートフォン４の位置推定部４０２において利用者位置を推定するので、第１の実施形態とは異なり、ランドマーク画像は送信情報に含まれなくてもよい。 Then, the request environment setting reception unit 401 of the smartphone 4 transmits the transmission information including the request environment setting input by the user via the operation unit 41 and the user position estimated by the position estimation unit 402 to the communication I / F 44 To the air conditioning control device 2 via
FIG. 13 is a diagram illustrating an example of transmission information according to the second embodiment.
As shown in FIG. 13, the transmission information according to the present embodiment includes a user ID (“0001”), a request environment setting input by the user via the operation unit 41 (“set temperature: ** ° C.”, “ Set humidity: **%, "set air volume: small", ...), information in which the user position ("x pc , y pc , z pc ") estimated by the position estimation unit 402 is associated with each other.
In the present embodiment, since the position estimation unit 402 of the smartphone 4 estimates the user position, unlike the first embodiment, the landmark image may not be included in the transmission information.
　また、空調制御装置２の位置取得部２０１は、スマートフォン４から送信情報を受信すると、当該送信情報に含まれる利用者位置を取得する。
　このような構成であっても、第１の実施形態と同様の効果を得ることが可能である。 Further, when the transmission information is received from the smartphone 4, the position acquisition unit 201 of the air conditioning control device 2 acquires the user position included in the transmission information.
Even with such a configuration, it is possible to obtain the same effect as that of the first embodiment.
　また、第１、第２の実施形態に係る空調制御装置２は、制御に用いる要素が、「温度」、「湿度」、「風量」等である旨を説明したが、他の実施形態はこの態様に限定されない。他の実施形態に係る空調制御装置２は、上述の空調に係る要素に加え、「照度」、「香り」、「お湯の温度」、「便座の洗浄強さ」など、人の快適性に関わる量であれば如何なる態様であってもよい。なお、上述の例の場合、当該他の実施形態に係る空調制御装置２は、空調用室内機３のみならず、照明機器、芳香器、給湯器、便座機器を制御の対象とする態様であってもよい。 In addition, although the air conditioning control device 2 according to the first and second embodiments described that the elements used for control are "temperature", "humidity", "air volume", etc., other embodiments are the same. It is not limited to the aspect. The air conditioning control device 2 according to the other embodiment relates to human comfort such as "illuminance", "aroma", "hot water temperature", and "washing strength of toilet seat" in addition to the above-mentioned elements related to air conditioning. It may be in any form as long as it is a quantity. In addition, in the case of the above-mentioned example, the air-conditioning control apparatus 2 which concerns on the said other embodiment is an aspect which makes an object of control not only the indoor unit 3 for air conditioning but a lighting apparatus, an aroma, water heater, and a toilet seat apparatus. May be
　また、上述の各実施形態においては、上述した空調制御装置２及びスマートフォン４の各種処理の過程は、プログラムの形式でコンピュータ読み取り可能な記録媒体に記憶されており、このプログラムをコンピュータが読み出して実行することによって上記各種処理が行われる。また、コンピュータ読み取り可能な記録媒体とは、磁気ディスク、光磁気ディスク、ＣＤ－ＲＯＭ、ＤＶＤ－ＲＯＭ、半導体メモリ等をいう。また、このコンピュータプログラムを通信回線によってコンピュータに配信し、この配信を受けたコンピュータが当該プログラムを実行するようにしても良い。 In each of the above-described embodiments, the processes of various processes of the above-described air conditioning control device 2 and the smartphone 4 are stored in a computer readable recording medium in the form of a program, and the computer reads and executes this program.

　上記プログラムは、上述した機能の一部を実現するためのものであってもよい。さらに、上述した機能をコンピュータシステムにすでに記録されているプログラムとの組み合わせで実現できるもの、いわゆる差分ファイル（差分プログラム）であってもよい。更に、空調制御装置２及びスマートフォン４は、他の実施形態においては、１台のコンピュータで構成されていても良いし、通信可能に接続された複数のコンピュータで構成されていてもよい。 The program may be for realizing a part of the functions described above. Furthermore, it may be a so-called difference file (difference program) that can realize the above-described functions in combination with a program already recorded in the computer system. Furthermore, in another embodiment, the air conditioning control device 2 and the smartphone 4 may be configured by one computer, or may be configured by a plurality of computers communicably connected.
　以上、本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれると同様に、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the invention. These embodiments can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the invention described in the claims and the equivalents thereof as well as included in the scope and the gist of the invention.
　例えば、上述の実施形態において、ランドマークＬのサイズが固定である態様について説明したが、これに限られることはない。ランドマークＬのサイズを可変とし、ランドマークＬそれぞれのサイズ（縦幅Ｈ、横幅Ｗ）を、ランドマーク情報に予め含めるようにしてもよい。
　また、ランドマークＬ（二次元コード）自体にサイズ（縦幅Ｈ、横幅Ｗ）を予め記録しておき、スマートフォン４のランドマーク画像取得部４００が二次元コード処理技術を用いて当該サイズを読み取るようにしてもよい。この場合、要求環境設定受付部４０１は、送信情報に、ランドマークＬのサイズを示す情報を追加して、空調制御装置２に送信するようにしてもよい。
　このようにすることで、ランドマークＬを設置する場所に応じて、適切なサイズのランドマークＬを採用することができる。 For example, in the above-mentioned embodiment, although a mode in which the size of the landmark L is fixed has been described, the present invention is not limited to this. The size of the landmark L may be variable, and the size (vertical width H, horizontal width W) of each landmark L may be included in the landmark information in advance.
Also, the size (vertical width H, horizontal width W) is recorded in advance in the landmark L (two-dimensional code) itself, and the landmark image acquisition unit 400 of the smartphone 4 reads the size using the two-dimensional code processing technology You may do so. In this case, the request environment setting reception unit 401 may add information indicating the size of the landmark L to the transmission information, and transmit the information to the air conditioning control device 2.
By doing this, it is possible to adopt an appropriately sized landmark L depending on the place where the landmark L is to be installed.
　また、上述の実施形態において、ランドマークＬが二次元コードである態様について説明したが、これに限られることはない。
　他の実施形態では、カメラ４３が撮影した画像からランドマークＬのサイズ及び形状の変形量が検出可能であれば、一次元コードであってもよいし、任意のマークであってもよい。ランドマークＬを任意のマークとする場合、大きさ及び位置が既知であればどのような形状であってもよく、例えば三角形、星形等の形状を有していてもよい。更に、空間内に設置されている空調システム１の埋め込みリモコン、ホワイトボード、コピー機、壁掛け時計、換気扇等の三次元の物体をランドマークとしてもよい。
　また、ランドマークＬは、例えば図１に示す検出パターンＦａ～Ｆｃのみからなるマークであってもよい。この場合、検出パターンＦａ～Ｆｃは、規定の縦幅Ｈ及び横幅Ｗを満たすように、互いに間隔を開けて配置される。 Moreover, in the above-mentioned embodiment, although the aspect which is the landmark L being a two-dimensional code was demonstrated, it is not restricted to this.
In another embodiment, as long as the deformation amount of the size and shape of the landmark L can be detected from the image captured by the camera 43, it may be a one-dimensional code or any mark. When the landmark L is an arbitrary mark, it may have any shape as long as its size and position are known, and may have, for example, a triangular shape, a star shape, or the like. Furthermore, a three-dimensional object such as an embedded remote control of the air conditioning system 1 installed in the space, a whiteboard, a copier, a wall clock, a ventilation fan, etc. may be used as the landmark.
Further, the landmark L may be, for example, a mark consisting only of the detection patterns Fa to Fc shown in FIG. In this case, the detection patterns Fa to Fc are spaced apart from each other so as to satisfy the prescribed vertical width H and horizontal width W.
　更に、他の実施形態では、例えば空調用室内機３のパネル、ルーバー３１等をランドマークとしてもよい。この場合、空調制御装置２の位置推定部２００又はスマートフォン４の位置推定部４０２は、ランドマーク画像に含まれるパネル又はルーバー３１のサイズ及び形状の変形量に基づいて、利用者位置を推定するようにしてもよい。
　また、この場合、利用者がどの方角から空調用室内機３を撮影したかを容易に検出できるよう、パネル又はルーバー３１の少なくとも一箇所以上に目印となるマーク（シール、ロゴマーク、ＬＥＤランプ）を設けるようにしてもよいし、空調用室内機３に設けられているセンサ（赤外線センサ、超音波センサ、カメラ）をマークの代用としてもよい。
　空調用室内機３の四方にルーバー３１が設けられている場合、これら四つのルーバー３１の開度の違いをランドマーク画像から検出するようにしてもよい。この場合、位置推定部２００（位置推定部４０２）は、現在の空調用室内機３の制御状態と、ルーバー３１それぞれの開度とを照らし合わせて、利用者がどの方角からランドマークを撮影したかを検出する。
　このようにすることで、空調用室内機３自体がランドマークを兼ねることができるので、ランドマークＬを生産、設置するコストを削減することが可能である。 Furthermore, in another embodiment, for example, a panel of the air conditioning indoor unit 3, a louver 31 or the like may be used as a landmark. In this case, the position estimation unit 200 of the air conditioning control device 2 or the position estimation unit 402 of the smartphone 4 estimates the user position based on the amount of deformation of the size or shape of the panel or louver 31 included in the landmark image. You may
Further, in this case, a mark (seal, logo mark, LED lamp) serving as a mark on at least one of the panel or the louver 31 so that the user can easily detect from which direction the air conditioning indoor unit 3 was photographed The sensor (infrared sensor, ultrasonic sensor, camera) provided in the air conditioning indoor unit 3 may be used as a substitute for the mark.
When louvers 31 are provided on four sides of the air conditioning indoor unit 3, the difference in the opening degree of the four louvers 31 may be detected from the landmark image. In this case, the position estimation unit 200 (position estimation unit 402) compares the current control state of the air conditioning indoor unit 3 with the opening degree of each of the louvers 31, and the user photographs the landmark from which direction To detect
By doing so, the air conditioning indoor unit 3 itself can also serve as a landmark, so that the cost of producing and installing the landmark L can be reduced.
　上述の少なくとも一の態様に係る空調制御装置、空調システム、空調制御方法、及びプログラムによれば、ランドマークから離れた位置にいる利用者の位置を推定することができる。 According to the air conditioning control device, the air conditioning system, the air conditioning control method, and the program according to at least one aspect described above, it is possible to estimate the position of the user at a position distant from the landmark.
