プロセスシステム構成機器位置表示装置、プロセスシステム構成機器位置表示プログラム、及び、プロセスシステム構成機器位置表示方法Process system component device position display device, process system component device position display program, and process system component device position display method
　本発明は、化学や電力等の分野における各種プラントのプロセスを制御するプロセスシステムにおいて、プロセスシステム構成機器の位置を表示するプロセスシステム構成機器位置表示装置に関し、特に、撮像した撮像画像にプロセスシステム構成機器の位置を表示するものに関する。 The present invention relates to a process system configuration apparatus position display device that displays the position of a process system configuration apparatus in a process system that controls processes of various plants in fields such as chemistry and electric power. It relates to the display of the position of the equipment.
　プロセスシステム構成機器位置表示装置に適用できる可能性がある従来のナビゲーションシステムついて図１９、図２０を用いて説明する。ナビゲーションシステムの情報処理端末３は、案内表示装置９の存在を検知すると、サーバ５に、目的地及び案内表示装置９の案内表示装置ＩＤを送信する。サーバ５は、案内表示装置９の位置を特定し、案内表示装置９とユーザが入力した目的地の間の距離を求める。目的地までの距離が一定以内である場合は、目的地である施設の画像を案内画面として、目的地までの距離が一定以内でない場合は、次に通る通路の画像、あるいは、通路の方向を示す矢印画像と、目的地名、目的地までの距離を合成した案内画面（図２０参照）を生成し、情報処理端末３に送信する。情報処理端末３は、受信した案内画面を案内表示装置９に送信し、案内表示装置９は案内画面を表示する。（以上、特許文献１参照）。 A conventional navigation system that may be applied to the process system component device position display device will be described with reference to FIGS. When detecting the presence of the guidance display device 9, the information processing terminal 3 of the navigation system transmits the destination and the guidance display device ID of the guidance display device 9 to the server 5. The server 5 specifies the position of the guidance display device 9 and obtains the distance between the guidance display device 9 and the destination input by the user. If the distance to the destination is within a certain range, the image of the facility that is the destination is used as a guide screen. If the distance to the destination is not within the certain range, the image of the next passage or the direction of the passage is displayed. A guide screen (see FIG. 20) in which the arrow image shown, the destination name, and the distance to the destination are combined is generated and transmitted to the information processing terminal 3. The information processing terminal 3 transmits the received guidance screen to the guidance display device 9, and the guidance display device 9 displays the guidance screen. (See Patent Document 1 above).

　前述のナビゲーションには、以下に示すような改善すべき点がある。情報処理端末３は、目的地までの距離が一定以内である場合は、目的地である施設の画像を案内画面として生成する。町における施設であれば、各施設毎に特徴があることが多く、実際に撮像した画像でなく予め用意した案内画面用の画像を表示したとしても所望の施設にたどり着くことができる。一方、プロセスシステムでは、配置されるプロセスシステム構成機器は同形状のものが大量に使用されている。このため、プロセスシステム構成機器について予め用意した画像を用いて案内画面を生成したとしても、ユーザは所望のプロセスシステム構成機器を特定できない可能性がある。また、同じ形状のプロセスシステム構成機器が近接して配置されることも多いため、案内画面だけでは、ユーザは、所望のプロセスシステム構成機器を特定できない可能性が高くなる。 The above-mentioned navigation has the following points to be improved. If the distance to the destination is within a certain range, the information processing terminal 3 generates an image of the facility that is the destination as a guidance screen. If it is a facility in a town, there are many characteristics for each facility, and even if an image for a guide screen prepared in advance is displayed instead of an actually captured image, the desired facility can be reached. On the other hand, in the process system, a large amount of process system components arranged in the same shape are used. For this reason, even if a guidance screen is generated using an image prepared in advance for a process system component device, the user may not be able to specify a desired process system component device. In addition, since process system components having the same shape are often arranged close to each other, there is a high possibility that the user cannot specify a desired process system component using only the guidance screen.
　そこで、本発明は、撮像した撮像画像にプロセスシステム構成機器の位置を表示するプロセスシステム構成機器位置表示装置を提供することを目的とする。 Therefore, an object of the present invention is to provide a process system constituent device position display device that displays the position of a process system constituent device on a captured image.

第２　データ
１．空間設定情報
　トラップ作動状態表示装置１０１は、メモリ１０１ｂに空間設定情報を記録保持している。空間設定情報は、３次元の実空間と、カメラユニット１０１ｇで撮像する２次元の撮像画像との対応関係を示す情報である。 Second data Space setting information The trap operation state display device 101 records and holds space setting information in the memory 101b. The space setting information is information indicating a correspondence relationship between a three-dimensional real space and a two-dimensional captured image captured by the camera unit 101g.
　空間設定情報について、以下において説明する。最初に、カメラユニット１０１ｇを用いて三次元の実空間中の対象物を２次元の撮像画像に撮像するときのモデルについて説明する。図５に示すように、ある対象物Ａをカメラユニット１０１ｇのレンズＬを通して撮像する際に、レンズＬの後方、レンズＬの中心Ｏから距離ｂの位置に形成される撮像面Ｐに像Ｂを形成する、とすると、レンズの公式により以下の関係が成立する。
（１／ａ）＋（１／ｂ）＝（１／ｆ）　・・・・・（１）
　なお、ａは、レンズ前方に存在する対象物Ａまでの距離を示し、ｆはレンズの焦点距離を示す。距離ｂに対して距離ａが十分に大きいとき、前述の式（１）の左辺第１項は無視でき、次の近似が成立する。
（１／ｂ）≒（１／ｆ）　・・・・・（２）
つまり、撮像面Ｐの中心Ｏから距離ｂは焦点距離ｆで近似できる。 The space setting information will be described below. First, a model for capturing a two-dimensional captured image of an object in a three-dimensional real space using the camera unit 101g will be described. As shown in FIG. 5, when an object A is imaged through the lens L of the camera unit 101g, an image B is formed on the imaging surface P formed at a distance b from the center O of the lens L behind the lens L. If formed, the following relationship is established by the lens formula.
(1 / a) + (1 / b) = (1 / f) (1)
Here, a indicates the distance to the object A existing in front of the lens, and f indicates the focal length of the lens. When the distance a is sufficiently larger than the distance b, the first term on the left side of the above equation (1) can be ignored, and the following approximation is established.
(1 / b) ≈ (1 / f) (2)
That is, the distance b from the center O of the imaging surface P can be approximated by the focal length f.
　このような近似が成立するとき、撮像面Ｐに対応する仮想的な撮像面Ｐ’を、レンズの前方、焦点距離ｆのところに設定すると、図６に示すような中心射影（透視射影）のモデルが得られる。ここで、Ｚ軸を、レンズＬの中心Ｏを通り、レンズＬに直交する直線とする。なお、このようなＺ軸は、カメラの光軸と呼ばれる。実空間に対して、レンズＬの中心Ｏを原点とする３次元の座標系をカメラ座標系として設定する。図６に示すように、実空間に存在する対象物Ｑは、カメラ座標系を用いて、座標（Ｘ，Ｙ，Ｚ）と表すことができる。 When such an approximation is established, if a virtual imaging plane P ′ corresponding to the imaging plane P is set in front of the lens and at a focal length f, a central projection (perspective projection) as shown in FIG. A model is obtained. Here, the Z axis is a straight line passing through the center O of the lens L and orthogonal to the lens L. Such a Z axis is called an optical axis of the camera. For the real space, a three-dimensional coordinate system having the origin O at the center O of the lens L is set as the camera coordinate system. As shown in FIG. 6, the object Q existing in the real space can be expressed as coordinates (X, Y, Z) using a camera coordinate system.
　中心射影のモデルでは、図６に示すように、撮像面Ｐ’は、レンズＬの中心Ｏから前方、焦点距離ｆの位置に存在する。撮像面Ｐ’に対して、撮像面Ｐ’とＺ軸との交点ｏを原点とする２次元の座標系を撮像座標系として設定する。撮像座標系においては、カメラ座標系のＸ軸、Ｙ軸のそれぞれと平行にｘ軸、ｙ軸を設定する。 In the center projection model, as shown in FIG. 6, the imaging surface P ′ is present forward from the center O of the lens L and at a focal length f. A two-dimensional coordinate system having an origin at an intersection o between the imaging surface P ′ and the Z axis is set as the imaging coordinate system for the imaging surface P ′. In the imaging coordinate system, the x axis and the y axis are set in parallel with the X axis and the Y axis of the camera coordinate system, respectively.
　対象物Ｑの撮像面Ｐ’への射影は、直線ＯＱと撮像面との交点ｑで与えられる。ここで、交点ｑの撮像座標系での座標（ｘ，ｙ）は、次式で与えられる。
ｘ＝ｆ（Ｘ／Ｚ），　ｙ＝ｆ（Ｙ／Ｚ）　・・・・・（３）
なお、式（３）に示すような対象物Ｑのカメラ座標系の座標（Ｘ，Ｙ，Ｚ）から撮像面上の射影の画像座標（ｘ，ｙ）への変換は、透視変換（ｐｅｒｓｐｅｃｔｉｖｅ　ｔｒａｎｓｆｏｒｍａｔｉｏｎ）と呼ばれる。 The projection of the object Q onto the imaging surface P ′ is given by the intersection point q between the straight line OQ and the imaging surface. Here, the coordinates (x, y) of the intersection point q in the imaging coordinate system are given by the following equations.
x = f (X / Z), y = f (Y / Z) (3)
Note that the transformation from the coordinates (X, Y, Z) of the camera coordinate system of the object Q to the image coordinates (x, y) of the projection on the imaging surface as shown in the equation (3) is a perspective transformation (perspective transformation). ).
　撮像面Ｐ’には、撮像可能領域Ｒｍａｘが設定される。撮像可能領域Ｒｍａｘは、撮像面Ｐ’において、カメラユニット１０１ｇの固体撮像素子ＩＳによって撮像できる最大領域を表している。つまり、撮像可能領域Ｒｍａｘは、固体撮像素子ＩＳの種類毎に異なり、固体撮像素子の種類に固有の値となる。撮像可能領域Ｒｍａｘは、一般的に矩形状の領域である。なお、図６に示すように、撮像可能領域Ｒｍａｘは、撮像面Ｐ’において、撮像可能領域Ｒｍａｘの中心が撮像平面座標系の原点ｏとなるように設定されている。 The imageable area Rmax is set on the imaging surface P ′. The imageable area Rmax represents the maximum area that can be imaged by the solid-state imaging element IS of the camera unit 101g on the imaging surface P ′. That is, the imageable region Rmax differs for each type of solid-state image sensor IS, and is a value specific to the type of solid-state image sensor. The imageable region Rmax is generally a rectangular region. As shown in FIG. 6, the imageable region Rmax is set such that the center of the imageable region Rmax is the origin o of the imaging plane coordinate system on the imaging surface P ′.
　また、撮像可能領域Ｒｍａｘの全て又は一部に対して、表示領域Ｒが設定される。表示領域Ｒは、撮像可能領域Ｒｍａｘで撮像した撮像画像のうち、ディスプレイ１０１ｃに表示される領域である。 Further, the display area R is set for all or a part of the imageable area Rmax. The display area R is an area displayed on the display 101c among the captured images captured in the imageable area Rmax.
　撮像面Ｐ’に表示領域Ｒを設定すると、対象物Ｑのカメラ座標系の位置によっては、対象物Ｑとカメラ座標系の原点Ｏとを結ぶ直線ＱＯと撮像面Ｐ’との交点ｑが、表示領域Ｒ内に存在する場合と、表示領域Ｒ内に存在しない場合とがある。交点ｑが表示領域Ｒ内に存在する場合とは、ディスプレイ１０１ｃに対象物Ｑが写っている場合を示し、一方、交点ｑが表示領域Ｒ内に存在しない場合とは、ディスプレイ１０１ｃに対象物Ｑが写っていない場合を示す。 When the display area R is set on the imaging plane P ′, depending on the position of the object Q in the camera coordinate system, the intersection q between the imaging plane P ′ and the straight line QO connecting the object Q and the origin O of the camera coordinate system is There is a case where it exists in the display area R and a case where it does not exist in the display area R. The case where the intersection point q is present in the display area R indicates a case where the object Q is shown on the display 101c, while the case where the intersection point q is not present in the display area R is that the object Q is present on the display 101c. The case where is not shown.
　図７に示すように、対象物Ｑ０（図６参照）について、対象物Ｑとカメラ座標系の原点Ｏとを結ぶ直線ＱＯと撮像面Ｐ’との交点ｑ０が、表示領域Ｒの外側、左斜め上の領域に位置する場合、つまり、表示領域Ｒ内に存在しない場合には、対象物Ｑ０は、撮像された撮像画像に写らない。なお、図７は、図６に示す撮像面Ｐ’をＺ軸方向に向かって見た状態を示している。以降、表示領域Ｒに含まれない領域を、左斜め上方撮像外領域Ｒ１、上方撮像外領域Ｒ２、右斜め上方撮像外領域Ｒ３、左方撮像外領域Ｒ４、右方撮像外領域Ｒ５、左斜め下方撮像外領域Ｒ６、下方撮像外領域Ｒ７、右斜め下方撮像外領域Ｒ８に分けて特定する。 As shown in FIG. 7, with respect to the object Q0 (see FIG. 6), the intersection q0 between the straight line QO connecting the object Q and the origin O of the camera coordinate system and the imaging plane P ′ is outside the display region R, left When located in the diagonally upper region, that is, when it does not exist in the display region R, the object Q0 is not captured in the captured image. FIG. 7 shows a state in which the imaging surface P ′ shown in FIG. 6 is viewed in the Z-axis direction. Thereafter, the areas not included in the display area R are the left diagonal upper imaging outer area R1, the upper imaging outer area R2, the right diagonal upper imaging outer area R3, the left imaging outer area R4, the right imaging outer area R5, and the left diagonal. The lower imaging outer area R6, the lower imaging outer area R7, and the right diagonally lower imaging outer area R8 are specified separately.
　以上より、空間設定情報としては、カメラユニット１０１ｇのレンズＬの焦点距離ｆ、固体撮像素子ＩＳの撮像可能領域Ｒｍａｘの大きさを設定する。なお、レンズＬの焦点距離ｆ、固体撮像素子ＩＳの撮像可能領域Ｒｍａｘの大きさは、トラップ作動状態表示装置１０１の種類毎に異なるため、トラップ作動状態表示装置１０１の種類毎に用意する。
As described above, as the space setting information, the focal length f of the lens L of the camera unit 101g and the size of the imageable region Rmax of the solid-state image sensor IS are set. Since the focal length f of the lens L and the size of the imageable region Rmax of the solid-state imaging device IS differ for each type of the trap operation state display device 101, they are prepared for each type of the trap operation state display device 101.
２．トラップ位置情報
　トラップ位置情報とは、スチームトラップが配置されている位置を示す情報である、トラップ作動状態表示装置１０１は、配置されているスチームトラップのトラップ位置情報をトラップ位置情報データベース（以下、トラップ位置情報ＤＢとする）としてメモリ１０１ｂに記憶保持している。 2. Trap position information Trap position information is information indicating a position where a steam trap is arranged. The trap operation state display device 101 uses a trap position information database (hereinafter referred to as trap position information) for trap position information of a arranged steam trap. The position information DB is stored in the memory 101b.
　トラップ位置情報ＤＢについて、図８を用いて説明する。トラップ位置情報ＤＢは、トラップＩＤ記述領域、トラップ位置記述領域を有している。トラップＩＤ記述領域には、各スチームトラップを一意に特定する識別番号が記述される。位置情報記述領域には、トラップＩＤによって特定されるスチームトラップが配置されている位置を、ＧＰＳシステムに従って特定される位置、及び、配置されている高さによって、記述される。例えば、図８において、トラップＩＤ「１」のスチームトラップは、ＧＰＳシステムに従って特定される位置「北緯３６度１２分４６．５０秒、東経１３９度２５分９２．３０秒」の高さ「１．００ｍ」の位置に配置されていることを示している。
The trap position information DB will be described with reference to FIG. The trap position information DB has a trap ID description area and a trap position description area. In the trap ID description area, an identification number for uniquely identifying each steam trap is described. In the position information description area, the position where the steam trap specified by the trap ID is arranged is described by the position specified according to the GPS system and the arranged height. For example, in FIG. 8, the steam trap with the trap ID “1” has a height “1 .1 at a position“ 36 degrees 12 minutes 46.50 north latitude, 139 degrees 25 minutes 92.30 seconds east longitude ”specified according to the GPS system. It is shown that it is arranged at the position of “00m”.

　トラップ作動状態表示システム１００を用いてスチームトラップの作動状態を表示させるときの、トラップ作動状態表示装置１０１のＣＰＵ１０１ａの動作について図９、図１０を用いて、トラップ作動状態取得装置１０３のＣＰＵ１０３ａの動作について図１１を用いて、また、中継装置１０５のＣＰＵ１０５ａの動作について図１２を用いて、それぞれ、説明する。トラップ作動状態表示装置１０１の使用者は、ディスプレイ１０１ｃに表示されている所定のアイコンを選択する等、トラップ作動状態表示プログラムを起動するため動作を行い、トラップ作動状態表示プログラムを起動する。 2. Display of Steam Trap Operating State Regarding the operation of the CPU 101a of the trap operating state display device 101 when displaying the operating state of the steam trap using the trap operating state display system 100, the trap operating state will be described with reference to FIGS. The operation of the CPU 103a of the acquisition device 103 will be described with reference to FIG. 11, and the operation of the CPU 105a of the relay device 105 will be described with reference to FIG. The user of the trap operation state display device 101 performs an operation for starting the trap operation state display program, such as selecting a predetermined icon displayed on the display 101c, and starts the trap operation state display program.
　図９に示すように、ＣＰＵ１０１ａは、トラップ作動状態表示プログラムを起動すると（Ｓ８０１）、近辺に存在する中継装置１０５に、トラップ作動状態の送信を要求するトラップ作動状態要求情報を送信する（Ｓ８０３）。 As shown in FIG. 9, when the CPU 101a starts the trap operation state display program (S801), it transmits trap operation state request information for requesting transmission of the trap operation state to the relay device 105 existing in the vicinity (S803). .
　図１１に示すように、中継装置１０５のＣＰＵ１０５ａは、トラップ作動状態要求情報を取得すると（Ｓ９０１）、メモリ１０５ｂに保持している中継トラップ情報を取得する（Ｓ９０３）。ＣＰＵ１０５ａは、取得した中継トラップ情報に基づき、自らの通信範囲に位置するスチームトラップ１０３を特定し、特定したスチームトラップ１０３にトラップ作動状態要求情報を送信する（Ｓ９０５）。 As shown in FIG. 11, when the CPU 105a of the relay apparatus 105 acquires trap operation state request information (S901), it acquires relay trap information held in the memory 105b (S903). Based on the acquired relay trap information, the CPU 105a identifies the steam trap 103 located in its own communication range, and transmits trap operation state request information to the identified steam trap 103 (S905).
　図１２に示すように、トラップ作動状態取得装置１０３のＣＰＵ１０３ａは、トラップ作動状態送信要求情報を取得すると（Ｓ１００１）、メモリ１０３ｂに保持している温度センサ１０３ｉ及び圧力センサ１０３ｊの値と、自らを特定するトラップＩＤ、及び、自らの位置を特定するトラップ位置情報を取得し（Ｓ１００３）、それらを関連づけたトラップ作動状態情報を生成する（Ｓ１００５）。そして、ＣＰＵ１０３ａは、生成したトラップ作動状態情報を、中継装置１０５に送信する（Ｓ１００７）。 As shown in FIG. 12, when acquiring the trap operation state transmission request information (S1001), the CPU 103a of the trap operation state acquisition device 103 obtains the values of the temperature sensor 103i and the pressure sensor 103j held in the memory 103b, and itself. The trap ID to be specified and the trap position information to specify its own position are acquired (S1003), and the trap operation state information in which they are associated is generated (S1005). Then, the CPU 103a transmits the generated trap operation state information to the relay device 105 (S1007).
　なお、トラップ作動状態取得装置１０３は、トラップ作動状態要求情報を取得するか否かにかかわらず、常時、所定時間が経過したと判断すると（Ｓ１０１１）、温度センサ１０３ｉ、圧力センサ１０３ｊからセンサ値を取得し（Ｓ１０１３）、メモリ１０３ｂに保存する（Ｓ１０１５）。 Note that if the trap operation state acquisition device 103 determines that the predetermined time has always passed regardless of whether or not the trap operation state request information is acquired (S1011), the sensor value is obtained from the temperature sensor 103i and the pressure sensor 103j. It is acquired (S1013) and stored in the memory 103b (S1015).
　図１１に戻って、中継装置１０５のＣＰＵ１０５ａは、トラップ作動状態要求情報を取得すると（Ｓ９０３）、トラップ作動状態要求情報を送信したトラップ作動状態表示装置１０１に送信する（Ｓ９０５）。 Returning to FIG. 11, when the CPU 105a of the relay device 105 acquires the trap operation state request information (S903), the CPU 105a transmits the trap operation state request information to the trap operation state display device 101 that has transmitted the trap operation state request information (S905).
　図９に戻って、トラップ作動状態表示装置１０１のＣＰＵ１０１ａは、トラップ作動状態情報を取得すると（Ｓ８０５）、取得したトラップ作動状態情報をメモリ１０１ｂに保持する（Ｓ８０７）。トラップ作動状態表示装置１０１のＣＰＵ１０１ａは、トラップ作動状態表示プログラムが起動している間、常時、配置されているスチームトラップからトラップ作動状態情報を取得するステップＳ８０３～ステップＳ８０７の処理を実行する。 Referring back to FIG. 9, when the CPU 101a of the trap operation state display device 101 acquires the trap operation state information (S805), it holds the acquired trap operation state information in the memory 101b (S807). The CPU 101a of the trap operation state display device 101 always executes the processing of steps S803 to S807 for acquiring trap operation state information from the arranged steam trap while the trap operation state display program is activated.
　図１０に示すように、トラップ作動状態表示装置１０１のＣＰＵ１０１ａは、トラップ作動状態情報の取得と並行して、カメラユニット１０１ｇを介して取得した撮像画像をディスプレイ１０１ｃに表示する（Ｓ８１１）。ＣＰＵ１０１ａは、撮像画像の表示に際し、図１３に示すように、表示領域Ｒを有する撮像領域表示枠Ｗをディスプレイ１０１ｃに表示する。ここでは、表示領域Ｒは、固定撮像素子ＩＳの撮像可能領域Ｒｍａｘ（図７参照）と同じとしている。 As shown in FIG. 10, the CPU 101a of the trap operation state display device 101 displays the captured image acquired via the camera unit 101g on the display 101c in parallel with the acquisition of the trap operation state information (S811). When displaying the captured image, the CPU 101a displays an imaging region display frame W having a display region R on the display 101c as shown in FIG. Here, the display region R is the same as the imageable region Rmax (see FIG. 7) of the fixed image sensor IS.
　また、ＣＰＵ１０１ａは、撮像画像表示枠Ｗ内に、使用者からのトラップＩＤの入力を受け付けるためのトラップＩＤ入力枠Ｗ１を形成する（図１３参照）。 Further, the CPU 101a forms a trap ID input frame W1 for accepting an input of a trap ID from the user in the captured image display frame W (see FIG. 13).
　ＣＰＵ１０１ａは、トラップＩＤ入力枠Ｗ１を介してトラップＩＤを取得すると（Ｓ８１３）、取得したトラップＩＤに対応するスチームトラップを対象スチームトラップに設定する。ＣＰＵ１０１ａは、対象スチームトラップのトラップＩＤに対応するトラップ位置情報をトラップ位置情報ＤＢから取得する（Ｓ８１５）。ＣＰＵ１０１ａは、メモリ１０１ｂから空間設定情報を取得する（Ｓ８１７）。 When the CPU 101a acquires the trap ID via the trap ID input frame W1 (S813), the CPU 101a sets the steam trap corresponding to the acquired trap ID as the target steam trap. The CPU 101a acquires trap position information corresponding to the trap ID of the target steam trap from the trap position information DB (S815). The CPU 101a acquires space setting information from the memory 101b (S817).
　ＣＰＵ１０１ａは、ＧＰＳ回路１０１ｄ、電子コンパス回路１０１ｅ、ジャイロセンサ回路１０１ｆから、それぞれのセンサ値を、撮像位置情報、撮像方位情報、撮像傾斜情報として、取得する（Ｓ８１９）。ＣＰＵ１０１ａは、取得したトラップ位置情報、撮像位置情報、撮像方位情報、撮像傾斜情報、及び、空間設定情報を用いて、カメラ座標系における対象スチームトラップの座標を算出する（Ｓ８２１）。なお、ＣＰＵ１０１ａは、撮像位置情報、撮像方位情報、及び、撮像傾斜情報からカメラ座標系を設定する。 The CPU 101a acquires the respective sensor values as imaging position information, imaging orientation information, and imaging inclination information from the GPS circuit 101d, the electronic compass circuit 101e, and the gyro sensor circuit 101f (S819). The CPU 101a calculates the coordinates of the target steam trap in the camera coordinate system using the acquired trap position information, imaging position information, imaging orientation information, imaging inclination information, and space setting information (S821). Note that the CPU 101a sets a camera coordinate system from the imaging position information, imaging orientation information, and imaging tilt information.
　ＣＰＵ１０１ａは、さらに、対象スチームトラップのカメラ座標系における座標から、前述の式（３）を用いて、撮像平面座標系における座標を算出する（Ｓ８２３）。なお、撮像平面座標系における座標を、対象スチームトラップのトラップ位置情報に対応する撮像平面座標系の位置を示す撮像平面対応トラップ位置とする。 The CPU 101a further calculates coordinates in the imaging plane coordinate system from the coordinates in the camera coordinate system of the target steam trap using the above-described equation (3) (S823). Note that the coordinates in the imaging plane coordinate system are taken as the imaging plane corresponding trap position indicating the position of the imaging plane coordinate system corresponding to the trap position information of the target steam trap.
　なお、トラップ作動状態表示装置１０１の撮像位置、撮像方向、撮像高さが変化することによって、表示領域Ｒにおける対象スチームトラップの位置は変化する。例えば、図１４に示すように、トラップ作動状態表示装置１０１の撮像位置、撮像方向、撮像高さの変化前に、座標軸（Ｘ軸、Ｙ軸、Ｚ軸）で表されるカメラ座標系、座標軸（ｘ軸、ｙ軸）で表れる撮像平面座標系が設定されており、カメラ座標系において対象スチームトラップがＱ（Ｘ，Ｙ，Ｚ）に位置し、撮像平面座標系において撮像平面対応トラップ位置はｑ（ｘ、ｙ）である。トラップ作動状態表示装置１０１の撮像位置、撮像方向の変化後に、座標軸（Ｘ１軸、Ｙ１軸、Ｚ１軸）で表されるカメラ座標系、座標軸（ｘ１軸、ｙ１軸）で表れる撮像平面座標系が設定される場合、カメラ座標系において対象スチームトラップはＱ１（Ｘ１，Ｙ１，Ｚ１）に位置することとなり、撮像平面対応トラップ位置はｑ１（ｘ１，ｙ１）となる。 Note that the position of the target steam trap in the display region R changes as the imaging position, imaging direction, and imaging height of the trap operating state display device 101 change. For example, as shown in FIG. 14, the camera coordinate system and coordinate axes represented by coordinate axes (X axis, Y axis, Z axis) before the change of the imaging position, imaging direction, and imaging height of the trap operation state display device 101. An imaging plane coordinate system represented by (x axis, y axis) is set, and the target steam trap is located at Q (X, Y, Z) in the camera coordinate system, and the trapping position corresponding to the imaging plane in the imaging plane coordinate system is q (x, y). After the change of the imaging position and imaging direction of the trap operation state display device 101, the camera coordinate system represented by the coordinate axes (X1, Y1, and Z1 axes) and the imaging plane coordinate system represented by the coordinate axes (x1, y1 axes) are obtained. When set, the target steam trap is located at Q1 (X1, Y1, Z1) in the camera coordinate system, and the trapping position corresponding to the imaging plane is q1 (x1, y1).
　図１０に戻って、ＣＰＵ１０１ａは、算出した撮像平面対応トラップ位置が、表示領域Ｒ内に存在するか否かを判断する（Ｓ８２５）。ＣＰＵ１０１ａは、撮像平面対応トラップ位置が表示領域Ｒ内に存在すると判断すると、スチームトラップが存在することを示すトラップマークを、ディスプレイ１０１ｃの表示領域表示枠における表示領域Ｒの撮像平面対応トラップ位置に対応する位置に表示する（Ｓ８２７）。また、ＣＰＵ１０１ａは、メモリ１０１ｂに記憶しているトラップ作動状態情報から、対象スチームトラップの温度センサ１０３ｉ、及び、圧力センサ１０３ｊの値を取得する（Ｓ８２９）。ＣＰＵ１０１ａは、取得した温度センサ１０３ｉ、及び、圧力センサ１０３ｊの値を、対象スチームトラップのトラップＩＤとともに、トラップマークに対応させて表示領域Ｒに表示する（Ｓ８３１）。 Referring back to FIG. 10, the CPU 101a determines whether or not the calculated imaging plane-corresponding trap position exists in the display area R (S825). When the CPU 101a determines that the trapping position corresponding to the imaging plane exists in the display area R, the trap mark indicating the presence of the steam trap corresponds to the trapping position corresponding to the imaging plane in the display area R in the display area display frame of the display 101c. Is displayed at the position to be operated (S827). Further, the CPU 101a acquires values of the temperature sensor 103i and the pressure sensor 103j of the target steam trap from the trap operation state information stored in the memory 101b (S829). The CPU 101a displays the acquired values of the temperature sensor 103i and the pressure sensor 103j together with the trap ID of the target steam trap in the display area R in association with the trap mark (S831).
　表示領域Ｒに、トラップマークに対応させて温度センサ１０３ｉ、及び、圧力センサ１０３ｊの値を、対象スチームトラップのトラップＩＤとともに表示した状態を図１５に示す。なお、図１５においては、表示領域Ｒに表示される撮像画像だけでなく、撮像外領域Ｒ１～Ｒ８に表示される画像についても表示している。図１５に示すように、対象スチームトラップの表示領域Ｒ上の位置にトラップマーク「Ｔ」を表示するとともに、トラップマークに対応して「トラップＩＤ、温度センサ１０３ｉの値、及び、圧力センサ１０３ｊの値を表示する。これにより、使用者は、撮像画像に表示されている対象スチームトラップの作動状態を容易に確認することができる。 FIG. 15 shows a state in which the values of the temperature sensor 103i and the pressure sensor 103j are displayed in the display area R in correspondence with the trap mark together with the trap ID of the target steam trap. In FIG. 15, not only the captured image displayed in the display area R but also the images displayed in the non-imaging areas R1 to R8 are displayed. As shown in FIG. 15, a trap mark “T” is displayed at a position on the display area R of the target steam trap, and “trap ID, value of temperature sensor 103i, and pressure sensor 103j In this way, the user can easily check the operating state of the target steam trap displayed in the captured image.
　図１０に戻って、ＣＰＵ１０１ａは、ステップＳ８１９において、撮像平面対応トラップ位置が表示領域Ｒ内に存在しないと判断すると、仮想撮像平面Ｐ’内における撮像平面対応トラップ位置と表示領域Ｒとの位置関係を判断する（Ｓ８３３）。具体的には、ＣＰＵ１０１ａは、撮像平面内トラップ位置が、図７に示す撮像外領域Ｒ１～Ｒ８のうち、どの撮像外領域に存在するのか否かを判断する。ＣＰＵ１０１ａは、スチームトラップの存在を示唆する表示であるトラップ存在示唆マークとして、対象スチームトラップが存在する撮像外領域の、表示領域Ｒから見た方向を指し示す矢印を、表示領域Ｒの外縁近傍に表示する（Ｓ８３５）。 Returning to FIG. 10, if the CPU 101a determines in step S819 that the imaging plane corresponding trap position does not exist in the display area R, the positional relationship between the imaging plane corresponding trap position and the display area R in the virtual imaging plane P ′. Is determined (S833). Specifically, the CPU 101a determines in which imaging outside area the imaging plane trap position is present in the imaging outside areas R1 to R8 shown in FIG. The CPU 101a displays an arrow indicating the direction seen from the display area R of the imaging outside area where the target steam trap exists as a trap existence suggestion mark which is a display suggesting the presence of the steam trap in the vicinity of the outer edge of the display area R. (S835).
　表示領域Ｒに、トラップ存在示唆マークを表示した状態を図１６に示す。なお、図１６においては、図１５と同様に、表示領域Ｒに表示される撮像画像だけでなく、撮像外領域Ｒ１～Ｒ８に表示される画像についても表示している。また、対象スチームトラップを丸印で囲んでいる。図１６に示すように、トラップＩＤ「１０」の対象スチームトラップが左斜め上方撮像外領域Ｒ１に存在する、つまり、表示領域Ｒ内に存在しない場合、トラップ存在示唆マークである矢印（以下、トラップ存在示唆マークＡＲ１）を表示領域Ｒの外縁近傍に表示する。この際、矢印であるトラップ存在示唆マークＡＲ１が左斜め上方、つまり、対象スチームトラップが存在する撮像外領域Ｒ１の表示領域Ｒから見た方向を指し示すように表示する。このように、トラップ存在示唆マークの表示により、使用者は、対象スチームトラップが表示されていなくとも、容易に、対象スチームトラップの位置を確認できる。 The state where the trap existence suggestion mark is displayed in the display area R is shown in FIG. In FIG. 16, as in FIG. 15, not only the captured image displayed in the display region R but also the images displayed in the non-imaging regions R1 to R8 are displayed. In addition, the target steam trap is circled. As shown in FIG. 16, when the target steam trap with the trap ID “10” exists in the upper left imaging outside area R1, that is, does not exist in the display area R, an arrow (hereinafter referred to as a trap existence suggestion mark) The presence suggestion mark AR1) is displayed near the outer edge of the display region R. At this time, the trap presence suggestion mark AR1, which is an arrow, is displayed so as to indicate an upper left direction, that is, a direction viewed from the display region R of the non-imaging region R1 where the target steam trap exists. Thus, the display of the trap presence suggestion mark allows the user to easily confirm the position of the target steam trap even if the target steam trap is not displayed.
　図１６に示す状態から、使用者が移動すると、この使用者の移動にともない、対象スチームトラップの位置も移動する。例えば、図１６に示す状態から、使用者が図面の奥側に向かって前進すると、図１７に示すように、対象スチームトラップは、左方撮像外領域Ｒ４に移動する。この場合、トラップ存在示唆マークである矢印（以下、トラップ存在示唆マークＡＲ３）が左方、つまり、対象スチームトラップが存在する撮像外領域Ｒ４の表示領域Ｒから見た方向を指し示すように表示する。このように、使用者の移動にともなって、トラップ存在示唆マークの表示が、トラップ存在示唆マークＡＲ１からトラップ存在示唆マークＡＲ３に変化するので、使用者はトラップ存在示唆マークの表示に従って移動するだけで、容易に、対象スチームトラップを見つけることができる。 When the user moves from the state shown in FIG. 16, the position of the target steam trap moves as the user moves. For example, when the user advances from the state shown in FIG. 16 toward the back side of the drawing, the target steam trap moves to the left imaging outside region R4 as shown in FIG. In this case, the arrow indicating the trap existence suggestion mark (hereinafter, trap existence suggestion mark AR3) is displayed to the left, that is, pointing to the direction viewed from the display area R of the non-imaging area R4 where the target steam trap exists. In this way, the display of the trap presence suggestion mark changes from the trap presence suggestion mark AR1 to the trap presence suggestion mark AR3 as the user moves, so the user only moves according to the display of the trap presence suggestion mark AR3. You can easily find the target steam trap.
　なお、ＣＰＵ１０１ａは、ステップＳ８１３において、所定時間内にトラップＩＤを取得できないと判断すると、既に対象スチームトラップが設定されているか否かを判断する（Ｓ８３７）。ＣＰＵ１０１ａは、対象スチームトラップが設定されていると判断すると、現在設定されている対象スチームトラップに対してステップＳ８１９以降の処理を実行する。一方、ＣＰＵ１０１ａは、ステップＳ８３７において、対象スチームトラップが設定されていないと判断すると、新たにトラップＩＤを取得するまで、撮像画像を表示すべく、ステップＳ８１１、Ｓ８１３の処理を実行する。 If the CPU 101a determines in step S813 that the trap ID cannot be acquired within the predetermined time, the CPU 101a determines whether or not the target steam trap has already been set (S837). If the CPU 101a determines that the target steam trap is set, the CPU 101a performs the processing from step S819 on for the currently set target steam trap. On the other hand, when determining in step S837 that the target steam trap is not set, the CPU 101a executes steps S811 and S813 to display the captured image until a new trap ID is acquired.
　図９に戻って、ＣＰＵ１０１ａは、トラップ作動状態表示プログラムが終了するまで（Ｓ８０９）、ステップＳ８０３～ステップＳ８０７の処理、及び、ステップＳ８１１～ステップＳ８３７の処理を実行する。
Returning to FIG. 9, the CPU 101a executes the processes of Steps S803 to S807 and the processes of Steps S811 to S837 until the trap operation state display program ends (S809).
