For example, the change of the installation state of the equipment F1 is confirmed by arranging the photograph data of the equipment F1 in time series. Alternatively, a folder for each equipment type is created, and the photo data of the equipment F1 to F6 is managed for each equipment type.
　次に、図５～７を参照して、タブレット３による設備Ｆ１～Ｆ６の撮影について説明する。図５は、タブレット３による設備撮影時のフローチャートであり、図６、７は、タブレット３から撮影対象設備までの距離算出を説明する模式図である。フローチャートの処理は、主にＣＰＵ３３によって行われるが、ＣＰＵ３３における撮影設備推定部４７が、天井高さであるフロア高さＬ２の情報をサーバコンピュータ５から取得する天井高さ取得部と、フロア２においてカメラ３１の床２ａからの撮影高さの情報（撮影者Ｈの身長Ｌ１）を取得する撮影高さ取得部と、撮影位置からの設備位置を演算する演算部として機能する。 Next, with reference to FIGS. 5 to 7, photographing of the facilities F1 to F6 by the tablet 3 will be described. FIG. 5 is a flowchart at the time of equipment photographing by the tablet 3, and FIGS. 6 and 7 are schematic diagrams for explaining the distance calculation from the tablet 3 to the equipment to be photographed. The processing of the flowchart is mainly performed by the CPU 33. In the floor 2, the photographing facility estimation unit 47 in the CPU 33 acquires information on the floor height L2 that is the ceiling height from the server computer 5. It functions as a shooting height acquisition unit that acquires information on the shooting height from the floor 2a of the camera 31 (height L1 of the photographer H) and a calculation unit that calculates the equipment position from the shooting position.
　各機能の詳細について詳しく説明する。図５のフローチャートにおけるステップＳ１０において、撮影位置情報取得部４４により撮影位置の情報を取得する。すなわち、撮影者Ｈは、撮影対象設備を撮影する前に、撮影位置Ｐ１をタブレット３に入力する。具体的な手順としては、撮影位置情報取得部４４は、図面情報に基づいて、工事現場のフロア２の図面をタブレット３の画面に表示する。撮影者Ｈは、このフロア２の図面を参照して、画面上で自身の位置（撮影位置Ｐ１）を指定する。つまり、画面上で自身の位置をタップする。この動作を図６において符号Ｓ１０で示す。この撮影位置Ｐ１において、撮影者Ｈは撮影対象設備の写真を撮影する。 The details of each function will be explained in detail. In step S10 in the flowchart of FIG. 5, the shooting position information acquisition unit 44 acquires shooting position information. That is, the photographer H inputs the photographing position P1 to the tablet 3 before photographing the equipment to be photographed. As a specific procedure, the photographing position information acquisition unit 44 displays a drawing of the floor 2 of the construction site on the screen of the tablet 3 based on the drawing information. The photographer H refers to the floor 2 drawing and designates his / her position (photographing position P1) on the screen. In other words, tap your position on the screen. This operation is indicated by reference numeral S10 in FIG. At this photographing position P1, the photographer H takes a picture of the equipment to be photographed.
　次に、ステップＳ１１において、センサ情報取得部４３によりタブレット３の鉛直方向Ｘに対する傾き角度θを検出する。すなわち、図７に示すように、撮影者Ｈは、タブレット３のカメラ３１を撮影対象設備に向ける。なお、撮影対象設備である空調機の室内機、照明、非常灯は、天井２ｂに配設されることが多いので、撮影者Ｈはタブレット３を上方に向けることになる。このとき、タブレット３の姿勢計測部３５によって、タブレット３のカメラ３１の鉛直方向Ｘに対する傾き角度θが検出されて、この傾き角度θはセンサ情報取得部４３に取得される。 Next, in step S11, the sensor information acquisition unit 43 detects the tilt angle θ of the tablet 3 with respect to the vertical direction X. That is, as shown in FIG. 7, the photographer H points the camera 31 of the tablet 3 toward the photographing target facility. In addition, since the indoor unit of an air conditioner, which is a photographing target facility, illumination, and emergency light are often arranged on the ceiling 2b, the photographer H points the tablet 3 upward. At this time, the inclination angle θ of the tablet 3 with respect to the vertical direction X of the camera 31 is detected by the posture measurement unit 35 of the tablet 3, and this inclination angle θ is acquired by the sensor information acquisition unit 43.
　ステップＳ１２において、タブレット３の姿勢計測部３５は、タブレット３のカメラ３１の方位を検出する。この方位情報はセンサ情報取得部４３に取得される。 In step S12, the posture measuring unit 35 of the tablet 3 detects the orientation of the camera 31 of the tablet 3. This orientation information is acquired by the sensor information acquisition unit 43.
　ステップＳ１３において、撮影設備推定部４７によりタブレット３とフロア２の天井２ｂとの間の距離を算出する。まず、タブレット３の撮影設備推定部４７は、撮影者Ｈの身長Ｌ１の入力を要求する。撮影者Ｈがタブレット３に身長Ｌ１を入力すると、タブレット３の撮影設備推定部４７は、図面情報から、フロア２の床２ａから天井２ｂまでのフロア高さＬ２の情報を読み出し、フロア高さＬ２から撮影者Ｈの身長Ｌ１を減算して、天井２ｂからのタブレット３のカメラ３１の概略距離を推定する。つまり、撮影者Ｈは顔と略同じ高さにおいてタブレット３を構えているので、タブレット３の高さと撮影者Ｈの身長Ｌ１とは略同じ高さになる。このように、下記式（１）により、天井２ｂとタブレット３との鉛直距離Ｌ３を算出する。なお、撮影者Ｈの身長Ｌ１は、タブレット３に事前に入力しておいてもよい。
　　　　　Ｌ３＝Ｌ２－Ｌ１・・・式（１） In step S <b> 13, the distance between the tablet 3 and the ceiling 2 b of the floor 2 is calculated by the photographing facility estimation unit 47. First, the imaging facility estimation unit 47 of the tablet 3 requests input of the height L1 of the photographer H. When the photographer H inputs the height L1 to the tablet 3, the photographing facility estimation unit 47 of the tablet 3 reads information on the floor height L2 from the floor 2a to the ceiling 2b of the floor 2 from the drawing information, and the floor height L2 From this, the height L1 of the photographer H is subtracted to estimate the approximate distance of the camera 31 of the tablet 3 from the ceiling 2b. That is, since the photographer H holds the tablet 3 at substantially the same height as the face, the height of the tablet 3 and the height L1 of the photographer H are substantially the same height. Thus, the vertical distance L3 between the ceiling 2b and the tablet 3 is calculated by the following formula (1). The height L1 of the photographer H may be input to the tablet 3 in advance.
L3 = L2-L1 Formula (1)
　ステップＳ１４において、撮影設備推定部４７によりタブレット３と撮影対象設備との間の距離を算出する。撮影設備推定部４７は、ステップＳ１１において取得した傾き角度θと、ステップＳ１３において算出した鉛直距離Ｌ３に基づき下記式（２）を演算することによって、撮影位置Ｐ１から撮影対象設備の中心位置Ｐ２までの水平距離Ｌ４を算出する。
　　　　　Ｌ４＝Ｌ３× tanθ・・・式（２） In step S14, the shooting facility estimation unit 47 calculates the distance between the tablet 3 and the shooting target facility. The imaging facility estimation unit 47 calculates the following equation (2) based on the inclination angle θ acquired in step S11 and the vertical distance L3 calculated in step S13, thereby capturing from the imaging position P1 to the center position P2 of the imaging target facility. The horizontal distance L4 is calculated.
L4 = L3 × tan θ (2)
　ステップＳ１５において、ステップＳ１１で指定した撮影位置Ｐ１、ステップＳ１２で取得したタブレット３の方位γ、ステップＳ１４で算出した水平距離Ｌ４に基づいて、撮影対象設備の中心位置Ｐ２を算出する。 In step S15, based on the photographing position P1 designated in step S11, the orientation γ of the tablet 3 obtained in step S12, and the horizontal distance L4 calculated in step S14, the center position P2 of the photographing target facility is calculated.
　ステップＳ１６において、撮影設備推定部４７は、撮影対象設備の中心位置Ｐ２とフロア図面上の設備位置情報とを照合する。撮影設備推定部４７は、フロア図面上に撮影対象設備の中心位置Ｐ２を重ね合わせて、撮影対象設備の中心位置Ｐ２に対応する設備を判定する。図６に示す場合では、撮影対象設備の中心位置Ｐ２が、設備Ｆ５に対応しているので、撮影対象設備は設備Ｆ５であると判定する。 In step S16, the photographing facility estimation unit 47 collates the center position P2 of the photographing target facility with the facility position information on the floor plan. The photographing facility estimation unit 47 determines the facility corresponding to the central position P2 of the photographing target facility by superimposing the central position P2 of the photographing target facility on the floor drawing. In the case shown in FIG. 6, since the center position P2 of the imaging target facility corresponds to the facility F5, it is determined that the imaging target facility is the facility F5.
　ステップＳ１７において、撮影設備推定部４７は、設備Ｆ５の写真データに設備Ｆ５の各種設備情報を付与する。すなわち、写真撮影部４１により撮影された写真データは、写真データ記録部４２に保存される。撮影設備推定部４７は、その写真データに設備Ｆ５の設備情報を付与して、この写真データが設備Ｆ５に関するものであることを関連付ける。そして、タブレット３は、その写真データをサーバコンピュータ５に送信する。設備Ｆ５以外の設備Ｆ１～Ｆ４、Ｆ６についても同様に撮影する。 In step S17, the imaging facility estimation unit 47 gives various facility information of the facility F5 to the photograph data of the facility F5. That is, the photograph data photographed by the photograph photographing unit 41 is stored in the photograph data recording unit 42. The photographing facility estimation unit 47 assigns facility information of the facility F5 to the photograph data, and associates that the photograph data relates to the facility F5. The tablet 3 transmits the photo data to the server computer 5. Pictures are taken in the same manner for the equipments F1 to F4 and F6 other than the equipment F5.
　次に、設備撮影時に、複数の設備が撮影された場合、例えば、撮影対象設備に隣接する他の設備も同時に撮影された場合について図８、９を参照して説明する。図８は、タブレット３による設備撮影時のフローチャートであり、図９は、タブレット３による撮影エリアＲを説明する模式図である。 Next, a case where a plurality of facilities are photographed during facility photographing, for example, a case where other facilities adjacent to the facility to be photographed are photographed simultaneously will be described with reference to FIGS. FIG. 8 is a flowchart at the time of equipment shooting by the tablet 3, and FIG. 9 is a schematic diagram for explaining a shooting area R by the tablet 3.
　図８のフローチャートにおいてステップＳ２０～Ｓ２４は、図５のフローチャートのステップＳ１０～Ｓ１４までと同様であるので、その説明を省略する。 In the flowchart of FIG. 8, steps S20 to S24 are the same as steps S10 to S14 of the flowchart of FIG.
　ステップＳ２５において、ステップＳ１５と同様に撮影対象設備の中心位置Ｐ２を算出した後に、さらに、撮影エリアＲを算出する。撮影エリアＲは、タブレット３のカメラ３１の画角Ｇθに基づいて算出する。すなわち、図９において、カメラ３１によるフロア２の撮影エリアＲを算出する。 In step S25, after calculating the center position P2 of the equipment to be imaged in the same manner as in step S15, the imaging area R is further calculated. The shooting area R is calculated based on the angle of view Gθ of the camera 31 of the tablet 3. That is, in FIG. 9, the shooting area R of the floor 2 by the camera 31 is calculated.
　ステップＳ２６において、撮影設備推定部４７は、撮影対象設備の中心位置Ｐ２に基づく撮影エリアＲに含まれる設備を照合する。撮影設備推定部４７は、撮影エリアＲをフロア図面上に重ね合わせて、この撮影エリアＲに、撮影対象設備の中心位置Ｐ２に対応する設備以外の設備があるかを判定する。 In step S26, the photographing facility estimation unit 47 collates facilities included in the photographing area R based on the center position P2 of the photographing target facility. The photographing facility estimation unit 47 superimposes the photographing area R on the floor drawing, and determines whether there is equipment other than the facility corresponding to the center position P2 of the photographing target facility in the photographing area R.
　図９に示す場合では、撮影対象設備の中心位置Ｐ２が設備Ｆ５に対応しているので、撮影エリアＲの略中心に位置する撮影設備は設備Ｆ５であると判定する。また、この設備Ｆ５以外に、設備Ｆ５に隣接する設備Ｆ４、Ｆ６が存在しているので、撮影写真には、設備Ｆ４、Ｆ５、Ｆ６が撮影されていると判定する。 In the case shown in FIG. 9, since the center position P2 of the equipment to be imaged corresponds to the equipment F5, it is determined that the imaging equipment located at the approximate center of the imaging area R is the equipment F5. Since there are facilities F4 and F6 adjacent to the facility F5 other than the facility F5, it is determined that the facilities F4, F5, and F6 are captured in the photograph.
　ステップＳ２７において、撮影設備推定部４７は、写真撮影部４１により撮影された写真データに設備Ｆ４、Ｆ５、Ｆ６の設備情報を付与する。そして、撮影設備推定部４７は、この写真データが設備Ｆ４、Ｆ５、Ｆ６に関するものであることを関連付けて、この写真データをサーバコンピュータ５に送信する。 In step S27, the photographing facility estimation unit 47 adds facility information of the facilities F4, F5, and F6 to the photograph data photographed by the photograph photographing unit 41. Then, the photographing facility estimation unit 47 associates that the photograph data relates to the facilities F4, F5, and F6 and transmits the photograph data to the server computer 5.
　このように、撮影位置Ｐ１から、撮影対象設備までの距離を距離測定器を用いずに、タブレット３による演算によって算出しているので、距離測定器が不要になりコストを抑制することができる。また、一般的に市販されているタブレット３を改良することなく使用できるので、この点に関してもコストを抑制することができ、また、携帯性に優れている。 As described above, since the distance from the photographing position P1 to the equipment to be photographed is calculated by the calculation by the tablet 3 without using the distance measuring device, the distance measuring device becomes unnecessary and the cost can be suppressed. Moreover, since it can use without improving the tablet 3 marketed generally, cost can be suppressed also about this point and it is excellent in portability.
　また、タブレット３のカメラ３１を撮影対象設備に向けることによって、撮影対象設備までの水平距離Ｌ４が自動的に算出されて、この水平距離Ｌ４、撮影位置Ｐ１、方位γ、図面情報、設備情報等に基づいて、撮影対象設備を特定することができる。その結果、撮影者Ｈは、特別な操作や準備を必要とせず、撮影対象設備を撮影するのみで、設備Ｆ１～Ｆ６の写真データを得ることができる。 Further, by directing the camera 31 of the tablet 3 toward the photographing target facility, the horizontal distance L4 to the photographing target facility is automatically calculated, and this horizontal distance L4, photographing position P1, azimuth γ, drawing information, facility information, etc. Based on this, it is possible to specify the equipment to be imaged. As a result, the photographer H can obtain the photograph data of the facilities F1 to F6 only by photographing the facility to be photographed without requiring any special operation or preparation.
　さらに、タブレット３からサーバコンピュータ５に送信する写真データに、写真データ以外の設備Ｆ１～Ｆ６に関する各種設備情報を自動的に付与することができるので、各種設備情報に基づく詳細な写真データ管理を行うことができる。 Furthermore, various pieces of equipment information related to the equipments F1 to F6 other than the picture data can be automatically added to the picture data transmitted from the tablet 3 to the server computer 5, so that detailed picture data management based on the various kinds of equipment information is performed. be able to.
　第２の実施形態においては、第１の実施形態における工事写真管理システム１００及びタブレット３と同様のハードウェア構成であるため、このハードウェア構成についての説明を省略する。第２の実施形態では、アプリケーションプログラムに基づく機能が相違しているので、この相違する部分について説明する。また、以下に説明する他の実施形態についても第１の実施形態と相違する点について説明する。 In the second embodiment, the hardware configuration is the same as that of the construction photo management system 100 and the tablet 3 in the first embodiment, and thus the description of the hardware configuration is omitted. In the second embodiment, since the functions based on the application program are different, the different parts will be described. Also, other embodiments described below will be described with respect to differences from the first embodiment.
　第２の実施形態では、撮影対象設備の動画撮影を行い、この動画から撮影対象設備の写真を抽出する。第２の実施形態におけるタブレット３の機能ブロックを図１０に示す。図１０に示すように、タブレット３は、図３に示す機能の他に、動画撮影を行う動画撮影部４１ａと、動画情報から、撮影対象設備の写真を抽出する設備写真抽出部４８との機能を備えている。動画撮影部４１ａは、カメラ３１の動画撮影機能によって実現される。設備写真抽出部４８はＣＰＵ３３によって実現される。 In the second embodiment, moving image shooting of the shooting target facility is performed, and a photograph of the shooting target facility is extracted from the moving image. FIG. 10 shows functional blocks of the tablet 3 in the second embodiment. As shown in FIG. 10, in addition to the functions shown in FIG. 3, the tablet 3 has functions of a moving image photographing unit 41a that performs moving image photographing and a facility photo extracting unit 48 that extracts a photograph of the photographing target facility from the moving image information. It has. The moving image shooting unit 41 a is realized by the moving image shooting function of the camera 31. The facility photo extraction unit 48 is realized by the CPU 33.
　動画撮影部４１ａによる動画撮影、設備写真抽出部４８による撮影対象設備の写真抽出について説明する。図１１にフロア２の動画撮影時の模式図を示す。なお、図１１では、フロア２に設備Ｆ５，Ｆ６が配置されている場合を示す。 The following describes the video shooting by the video shooting unit 41a and the photo extraction of the equipment to be shot by the facility photo extraction unit 48. FIG. 11 is a schematic diagram at the time of moving image shooting on the floor 2. In addition, in FIG. 11, the case where the facilities F5 and F6 are arrange | positioned on the floor 2 is shown.
　図１１に示すように、撮影者Ｈは、図６における撮影位置Ｐ１の指定と同様に、撮影位置Ｐ１を指定する。この撮影位置Ｐ１から、フロア２の動画を撮影する。例えば、フロア２の位置Ｄ１から位置Ｄ２に向かってフロア２に設置されている設備Ｆ５，Ｆ６を動画撮影する。これにより領域Ｒ１が動画撮影される。動画撮影中、設備写真抽出部４８は、撮影設備推定部４７により算出される中心位置Ｐ２を取得し、動画撮影部４１ａからの動画データと、中心位置Ｐ２の情報とを同時に記録して動画データと中心位置Ｐ２とを対応づける。 As shown in FIG. 11, the photographer H designates the photographing position P1 similarly to the designation of the photographing position P1 in FIG. A moving image of the floor 2 is photographed from the photographing position P1. For example, moving images are taken of the facilities F5 and F6 installed on the floor 2 from the position D1 of the floor 2 toward the position D2. As a result, the region R1 is captured as a moving image. During movie shooting, the facility photo extraction unit 48 acquires the center position P2 calculated by the shooting facility estimation unit 47, and simultaneously records the movie data from the movie shooting unit 41a and the information on the center position P2 to store movie data. And the center position P2.
　一方、設備写真抽出部４８は、図面情報及び設備情報に基づいて、設備Ｆ５，Ｆ６の配置位置を確認する。そして、動画データにおける中心位置Ｐ２と、設備Ｆ５，Ｆ６の配置位置とが一致したときの動画データから静止画を抽出する。この静止画を設備Ｆ５，Ｆ６の写真データとして記録する。 On the other hand, the facility photo extraction unit 48 confirms the arrangement positions of the facilities F5 and F6 based on the drawing information and the facility information. Then, a still image is extracted from the moving image data when the center position P2 in the moving image data matches the arrangement positions of the facilities F5 and F6. This still image is recorded as photograph data of the facilities F5 and F6.
　このようにフロア２を動画撮影することによって、フロア２の動画から設備Ｆ５，Ｆ６を抽出することができる。このため、設備Ｆ５，Ｆ６を個別に写真撮影する手間を省くことができる。 By taking a video of floor 2 in this way, facilities F5 and F6 can be extracted from the video on floor 2. For this reason, it is possible to save the trouble of individually photographing the facilities F5 and F6.
　なお、動画撮影中に撮影者Ｈに特定の動作をさせて、そのときの写真及び写っている設備情報を記録するようにしてもよい。例えば、動画撮影中に、設備Ｆ５が撮影された場合に、特定の動作として動画データに所定のマークを付与する。また、動画撮影中に、タブレット３の画面上に、設備Ｆ５，Ｆ６が存在する方向を指示する矢印等を表示させてもよい。 It should be noted that the photographer H may be caused to perform a specific action during video recording, and the photograph at that time and the equipment information that is shown may be recorded. For example, when the equipment F5 is shot during moving image shooting, a predetermined mark is given to the moving image data as a specific operation. Moreover, you may display the arrow etc. which instruct | indicate the direction where the apparatuses F5 and F6 exist on the screen of the tablet 3 during video recording.
　第３の実施形態では、撮影者Ｈの姿勢変化による天井２ｂとタブレット３との鉛直距離Ｌ５を補正する。第３の実施形態におけるタブレット３の機能ブロックを図１２に示す。図１２に示すように、タブレット３は、図３に示す機能の他に、鉛直距離補正部４９を備えている。 In the third embodiment, the vertical distance L5 between the ceiling 2b and the tablet 3 due to the posture change of the photographer H is corrected. FIG. 12 shows functional blocks of the tablet 3 in the third embodiment. As illustrated in FIG. 12, the tablet 3 includes a vertical distance correction unit 49 in addition to the functions illustrated in FIG. 3.
　鉛直距離補正部４９は、撮影者Ｈが直立している状態からかがんで撮影者Ｈの姿勢が変化した場合に、タブレット３（カメラ３１）の天井２ｂからの鉛直距離Ｌ３も変化するので、この変化を補正するものである。鉛直距離補正部４９はＣＰＵ３３によって実現される。 The vertical distance correction unit 49 changes the vertical distance L3 from the ceiling 2b of the tablet 3 (camera 31) when the posture of the photographer H changes from the state where the photographer H stands upright. This change is corrected. The vertical distance correction unit 49 is realized by the CPU 33.
　図１３に示すように、工事現場では、設備を撮影するときにかがむことがある。このため、このような状態をタブレット３の姿勢計測部３５によって検出する。このような状態が検出されると、鉛直距離補正部４９は、タブレット３と天井２ｂとの鉛直距離Ｌ５を補正する。例えば、姿勢計測部３５によって所定角度以上の傾き角度が検出された場合、タブレット３の位置が５０ｃｍ（補正距離Ｌ６）下がったと推定して鉛直距離Ｌ５を補正する。補正後の鉛直距離Ｌ５は下記式（３）によりにより算出できる。
　　　　　Ｌ５＝Ｌ２－（Ｌ１－Ｌ６）・・・式（３） As shown in FIG. 13, at the construction site, the equipment may bend down when photographing. For this reason, such a state is detected by the posture measuring unit 35 of the tablet 3. When such a state is detected, the vertical distance correction unit 49 corrects the vertical distance L5 between the tablet 3 and the ceiling 2b. For example, when an inclination angle equal to or larger than a predetermined angle is detected by the posture measurement unit 35, the vertical distance L5 is corrected by estimating that the position of the tablet 3 has decreased by 50 cm (correction distance L6). The corrected vertical distance L5 can be calculated by the following equation (3).
L5 = L2- (L1-L6) Formula (3)
　なお、一例として補正距離Ｌ６を５０ｃｍとしたが、撮影者Ｈの身長等により補正距離Ｌ６は適宜修正することができる。例えば、鉛直距離補正時に、補正距離Ｌ６をタブレット３の画面上に表示して、鉛直距離補正を行うときに、この補正距離Ｌ６を表示するとともに確認及び修正できるようにしてもよい。 Although the correction distance L6 is set to 50 cm as an example, the correction distance L6 can be appropriately corrected according to the height of the photographer H. For example, when correcting the vertical distance, the correction distance L6 may be displayed on the screen of the tablet 3, and when the vertical distance correction is performed, the correction distance L6 may be displayed and confirmed and corrected.
　このように、撮影者Ｈの姿勢に応じて、タブレット３（カメラ３１）の高さ、すなわち、鉛直距離Ｌ５を補正するので、撮影位置Ｐ１からの設備Ｆ１～Ｆ６までの距離を高精度に算出することができ、設備Ｆ１～Ｆ６の特定を高精度に行うことができる。 In this way, the height of the tablet 3 (camera 31), that is, the vertical distance L5 is corrected according to the posture of the photographer H, so that the distance from the photographing position P1 to the facilities F1 to F6 is calculated with high accuracy. Therefore, the facilities F1 to F6 can be specified with high accuracy.
　第４の実施形態におけるタブレット３の機能ブロックを図１４に示す。第４の実施形態では、サーバコンピュータ５から設備に関する設備情報が得られない場合を想定している。例えば、ビル１の基本的な図面情報（室内高さ、各フロア形状等）は、サーバコンピュータ５から取得することができるが、ビル１のフロア２に配置される設備の設備情報がサーバコンピュータ５に入力されていない場合がある。なお、このような場合でも、サーバコンピュータ５には、一般的な設備の種別を識別するための識別画像データが記憶されている。すなわち、後述する画像マッチング処理に使用する室内機、照明、非常灯等の各種設備の種別を識別するための識別画像データが記憶されている。 FIG. 14 shows functional blocks of the tablet 3 in the fourth embodiment. In the fourth embodiment, it is assumed that facility information regarding facilities cannot be obtained from the server computer 5. For example, basic drawing information (indoor height, each floor shape, etc.) of the building 1 can be acquired from the server computer 5, but the facility information of the equipment arranged on the floor 2 of the building 1 is stored in the server computer 5. May not be entered. Even in such a case, the server computer 5 stores identification image data for identifying a general facility type. That is, identification image data for identifying the types of various equipment such as indoor units, lighting, and emergency lights used for image matching processing described later is stored.
　図１４に示すように、タブレット３は、画像マッチング処理に使用する識別画像データを取得する識別画像情報取得部５０と、識別画像データに基づいて撮影された設備の種別を識別する設備識別部５１と、フロア２において識別された設備の配置図を作成する設備配置図作成部５２との機能を備えている。識別画像情報取得部５０、設備識別部５１及び設備配置図作成部５２はＣＰＵ３３によって実現される。 As illustrated in FIG. 14, the tablet 3 includes an identification image information acquisition unit 50 that acquires identification image data used for image matching processing, and a facility identification unit 51 that identifies the type of equipment photographed based on the identification image data. And a facility layout drawing creation unit 52 that creates a layout map of the facilities identified on the floor 2. The identification image information acquisition unit 50, the facility identification unit 51, and the facility layout drawing creation unit 52 are realized by the CPU 33.
　識別画像情報取得部５０は、サーバコンピュータ５から室内機、照明、非常灯の各種設備の種別を識別するための識別画像データをダウンロードする。識別画像データは、室内機、照明、非常灯に関してそれぞれの特徴点を備えている。 The identification image information acquisition unit 50 downloads identification image data for identifying the types of indoor units, lighting, and emergency lights from the server computer 5. The identification image data has respective feature points for the indoor unit, lighting, and emergency light.
　設備識別部５１は、撮影した写真データと識別画像データとに関して画像マッチング処理を行い、写真データの設備が室内機、照明、非常灯のいずれかであるかを識別する。この識別は、写真データ上の特徴点と、識別画像データの特徴点をと比較することにより行われ、写真データ上の特徴点が、室内機、照明、非常灯のいずれかの特徴点と一致したときに、写真データの設備が、その一致した設備であると判断される。 The facility identification unit 51 performs image matching processing on the photographed photograph data and the identification image data, and identifies whether the facility of the photograph data is an indoor unit, an illumination, or an emergency light. This identification is performed by comparing the feature point on the photo data with the feature point on the identification image data, and the feature point on the photo data matches the feature point of the indoor unit, lighting, or emergency light. When this is done, it is determined that the equipment of the photo data is the matched equipment.
　設備配置図作成部５２は、設備識別部５１によって識別された設備を、フロア２のレイアウトに沿って配置する。 The facility layout drawing creation unit 52 arranges the facilities identified by the facility identification unit 51 along the layout of the floor 2.
　次に、設備識別部５１、設備配置図作成部５２の機能について詳しく説明する。工事現場において、タブレット３は、図面情報取得部４５によりサーバコンピュータ５から図面情報を取得する。また、タブレット３は、設備情報取得部４６によりサーバコンピュータ５から設備情報の取得を試みるが、サーバコンピュータ５に工事現場のビル１に設置される設備に関する設備情報が登録されていない場合がある。このため、工事現場のビル１に設置される設備に関する設備情報を取得できない。 Next, functions of the facility identification unit 51 and the facility layout drawing creation unit 52 will be described in detail. At the construction site, the tablet 3 acquires drawing information from the server computer 5 by the drawing information acquisition unit 45. Moreover, although the tablet 3 tries acquisition of equipment information from the server computer 5 by the equipment information acquisition part 46, the equipment information regarding the equipment installed in the building 1 of a construction site may not be registered into the server computer 5. For this reason, the equipment information regarding the equipment installed in the building 1 at the construction site cannot be acquired.
　このような場合には、サーバコンピュータ５から室内機、照明、非常灯の各種設備の識別画像データをダウンロードする。識別画像データは、設備のカタログや過去に撮影された設備の画像データをデータベース化して、各設備の特徴点をまとめたものである。 In such a case, identification image data of various equipment such as indoor units, lighting, and emergency lights is downloaded from the server computer 5. The identification image data is a database of facility catalogs and facility image data taken in the past, and the feature points of each facility are summarized.
　設備識別部５１は、写真撮影部４１で撮影された写真データと、識別画像データとを画像マッチング処理して、写真データに適合する設備の種別を識別する。 The facility identification unit 51 performs image matching processing on the photograph data photographed by the photograph photographing unit 41 and the identification image data, and identifies the type of facility suitable for the photograph data.
　撮影設備推定部４７は、設備識別部５１にて識別された写真データに、当該写真データに適合する設備の種別、撮影位置、撮影日時等の情報を付与して写真データ記録部４２に記録する。 The photographing facility estimation unit 47 adds information such as the type of facility suitable for the photograph data, the photographing position, and the photographing date and time to the photograph data identified by the facility identification unit 51 and records the information in the photograph data recording unit 42. .
　一方、撮影設備推定部４７は、写真データ、設備種別、撮影位置情報を、設備配置図作成部５２に送る。設備配置図作成部５２は、これら情報に基づいて、フロア２のレイアウト図において、写真データに適合する設備を配置する。すなわち、何も配置されていないフロア２のレイアウト図に、写真撮影した設備を順次配置して、フロア２における設備レイアウト図を作成する。 On the other hand, the photographing facility estimation unit 47 sends the photograph data, the facility type, and the photographing position information to the facility layout drawing creation unit 52. Based on these pieces of information, the equipment layout drawing creation unit 52 arranges equipment suitable for the photographic data in the layout diagram of the floor 2. That is, the equipment taken on the floor 2 is sequentially arranged on the layout drawing of the floor 2 where nothing is arranged, and the equipment layout diagram on the floor 2 is created.
　このように、工事現場において、設備に関する設備情報、特に、設備のフロア２の設置位置情報が入手できない場合であっても、設備の写真を撮影することによって、設備の種別を識別でき、また、フロア２における設備のレイアウト図も作成することができる。 In this way, in the construction site, even when the facility information about the facility, in particular, the installation position information of the floor 2 of the facility is not available, the type of the facility can be identified by taking a photograph of the facility, A layout diagram of equipment on the floor 2 can also be created.
　また、サーバコンピュータ５から設備に関する設備情報を取得できる場合には、この設備情報と、画像マッチング処理により識別された設備の種別情報とが整合すれば、より確実に写真データの設備を特定することができる。また、両者が不整合である場合には、再度、写真データの特定を行うことにより、写真データの設備の特定を向上することができる。 In addition, when the facility information about the facility can be acquired from the server computer 5, if the facility information matches the facility type information identified by the image matching process, the facility of the photo data can be specified more reliably. Can do. If the two are inconsistent, the specification of the photo data equipment can be improved by specifying the photo data again.
　なお、写真データに複数の設備が存在する場合、これら複数の設備の写真データに対して画像マッチング処理を行ってもよい。また、フロア２の平面レイアウト図だけでなく、３次元モデルのレイアウト図を作成してもよい。さらに、作成したレイアウト図の情報を、ＢＩＭ（Ｂｕｉｌｄｉｎｇ Ｉｎｆｏｒｍａｔｉｏｎ Ｍｏｄｅｌｉｎｇ）として、ビル１の総合的な情報管理に利用してもよい。 In addition, when there are a plurality of facilities in the photo data, image matching processing may be performed on the photo data of the plurality of facilities. Further, not only a planar layout diagram of the floor 2 but also a three-dimensional model layout diagram may be created. Furthermore, the information of the created layout diagram may be used for comprehensive information management of the building 1 as BIM (Building Information Modeling).
　第５の実施形態におけるタブレット３の機能ブロックを図１５に示す。第５の実施形態では、工事現場で撮影する設備の撮影設備リストを事前に作成し、この撮影設備リストに基づいて設備の撮影を行う。 FIG. 15 shows functional blocks of the tablet 3 in the fifth embodiment. In the fifth embodiment, a photographing equipment list of equipment to be photographed at a construction site is created in advance, and equipment is photographed based on the photographing equipment list.
　図１５に示すように、タブレット３は、撮影設備をリストアップして、撮影設備リストを作成する撮影設備リスト作成部５３と、撮影設備リストの設備と撮影された設備とを照合する撮影設備照合部５４との機能を備えている。撮影設備リスト作成部５３及び撮影設備照合部５４はＣＰＵ３３によって実現される。 As shown in FIG. 15, the tablet 3 lists the photographing facilities, and the photographing facility list creation unit 53 that creates the photographing facility list, and the photographing facility collation that collates the facilities in the photographing facility list with the photographed facilities. A function with the unit 54 is provided. The photographing facility list creation unit 53 and the photographing facility verification unit 54 are realized by the CPU 33.
　撮影設備リスト作成部５３は、図面情報及び設備情報に基づいて、工事現場において今回撮影する設備をリストアップして撮影設備リストを作成する。 The photographing equipment list creation unit 53 creates a photographing equipment list by listing the equipment to be photographed at the construction site based on the drawing information and the equipment information.
　撮影設備照合部５４は、工事現場において、実際に撮影した設備と、撮影設備リストで対象となっている設備とを照合する。そして、撮影設備リストで対象となっている設備の全ての設備の撮影が完了したことを確認する。このとき、撮影設備リストの対象となっている設備のうち撮影が完了していない設備があれば、設備の撮り忘れがあると判断して撮影者Ｈに警告する。 The photographing equipment collation unit 54 collates the equipment actually photographed with the equipment that is the subject of the photographing equipment list at the construction site. Then, it is confirmed that the photographing of all the facilities of the target equipment in the photographing equipment list has been completed. At this time, if there is a facility that has not been photographed among the facilities that are the subject of the photographing facility list, it is determined that the facility has forgotten to photograph, and the photographer H is warned.
　次に、撮影設備リスト作成部５３及び撮影設備照合部５４の機能について詳しく説明する。図１６は、図面情報及び設備情報に基づいて作成された撮影設備リストＥ１の一例を示す。図１６における撮影設備リストＥ１は、工事現場のビル１の５階のフロア２において撮影する設備をリストアップしたものである。すなわち、撮影設備リストＥ１は、撮影対象のフロア情報の項目Ｅ１１、撮影対象設備の項目Ｅ１２、その撮影対象設備の撮影状況の項目Ｅ１３をまとめたものである。 Next, functions of the photographing equipment list creation unit 53 and the photographing equipment verification unit 54 will be described in detail. FIG. 16 shows an example of the photographing equipment list E1 created based on the drawing information and the equipment information. The imaging facility list E1 in FIG. 16 is a list of facilities to be photographed on the floor 2 on the fifth floor of the building 1 at the construction site. That is, the photographing facility list E1 is a collection of items E11 of floor information to be photographed, items E12 of the facility to be photographed, and items E13 of the photographing state of the facility to be photographed.
　工事現場のビル１のフロア２で設備の撮影が行われると、撮影状況の項目Ｅ１３に「済」が入力される。図１６では、設備Ｆ１～Ｆ３，Ｆ５が撮影済みであり、設備Ｆ４が未撮影である状態を示している。この状態で撮影者Ｈが、設備撮影を終了しようとすると、タブレット３の画面上に設備Ｆ４が未撮影であることを警告する。 When the equipment is photographed on the floor 2 of the building 1 at the construction site, “Done” is entered in the photographing condition item E13. FIG. 16 shows a state where the facilities F1 to F3 and F5 have been photographed and the facility F4 has not been photographed. In this state, when the photographer H tries to end the facility photographing, the photographer H warns on the screen of the tablet 3 that the facility F4 has not been photographed.
　この結果、撮影者Ｈに設備Ｆ４の撮影を促すことができ、設備Ｆ４の撮り忘れを防止することができる。特に、工事現場における設備撮影では、大量の写真撮影を行うために、設備写真の撮り忘れが発生することがある。この設備写真の撮り忘れが発生すると、再度、工事現場に行って撮影する必要が生じるが、工事現場において、撮り忘れの有無を確認することができるので、写真撮影を効率的に行うことができる。 As a result, the photographer H can be encouraged to shoot the equipment F4, and forgetting to take the equipment F4 can be prevented. In particular, when photographing equipment at a construction site, forgetting to take equipment photographs may occur because a large number of photographs are taken. If you forget to take a picture of this equipment, you will need to go to the construction site again to take a picture. However, you can check the presence or absence of forgetting to take the picture at the construction site, so you can efficiently take a picture. .
　また、撮影設備リストＥ１として、特定の設備を抽出して撮影設備リストＥ１を作成することもできる。例えば、図１６における撮影設備リストＥ１において、設備Ｆ１，Ｆ３，Ｆ４のみを撮影対象設備としてもよい。 In addition, as the photographing equipment list E1, specific equipment can be extracted to create the photographing equipment list E1. For example, in the photographing facility list E1 in FIG. 16, only the facilities F1, F3, and F4 may be the photographing target facilities.
　第６の実施形態におけるタブレット３の機能ブロックを図１７に示す。第６の実施形態では、写真データ記録部４２に記憶されている写真データ、例えば、所定のフロア２において撮影された設備写真を用いて、当該フロア２以外のフロア２で使用する他室撮影設備リストＥ３（図１８参照）を作成する。 FIG. 17 shows functional blocks of the tablet 3 in the sixth embodiment. In the sixth embodiment, the photo data stored in the photo data recording unit 42, for example, the other room photographing equipment used on the floor 2 other than the floor 2 using the equipment photograph taken on the predetermined floor 2 A list E3 (see FIG. 18) is created.
　第６の実施形態は、第５の実施形態と基本的に機能ブロックが同様であり、相違する点は、撮影設備リスト作成部５３が、写真データ記録部４２の写真データを使用して他室撮影設備リストＥ３（図１８参照）を作成する点である。 The sixth embodiment basically has the same functional blocks as the fifth embodiment, and the difference is that the photographing equipment list creation unit 53 uses the photo data of the photo data recording unit 42 to create another room. The imaging equipment list E3 (see FIG. 18) is created.
　ビル１、ホテル、マンション等の建物においては、各フロア２における設備配置が同一であることが多い。このため、撮影設備リスト作成部５３は、３階のフロア２において設備Ｆ１～Ｆ３の写真を撮影した場合、設備Ｆ１～Ｆ３に基づいて、図１８に示すように、撮影設備リストＥ２を作成する。撮影設備リストＥ２は、撮影設備リストＥ１と同様に、撮影対象のフロア情報の項目Ｅ２１、撮影対象設備の項目Ｅ２２、その撮影対象設備の撮影状況の項目Ｅ２３を備えている。 In buildings 1, hotels, condominiums, etc., the equipment layout on each floor 2 is often the same. For this reason, when photographing the facilities F1 to F3 on the floor 2 on the third floor, the photographing facility list creation unit 53 creates a photographing facility list E2 based on the facilities F1 to F3 as shown in FIG. . Similar to the shooting equipment list E1, the shooting equipment list E2 includes a floor information item E21 to be shot, a shooting target equipment item E22, and a shooting status item E23 of the shooting target equipment.
　そして、３階のフロア２と４階のフロア２との設備数、設備位置、設備種別等が同一であるので、この撮影設備リストＥ２に基づいて、４階のフロア２で使用する他室撮影設備リストＥ３を作成する。他室撮影設備リストＥ３は、撮影設備リストＥ２とフロア階数が異なるのみであり、その他の条件は同一である。他室撮影設備リストＥ３の作成後、この他室撮影設備リストＥ３に基づいて、撮影設備照合部５４は、第５の実施形態と同様に、工事現場において、実際に撮影した設備と、他室撮影設備リストＥ３で対象となっている設備とを照合する。４階のフロア２の工事現場で設備の撮影が行われると、撮影状況の項目Ｅ３３に「済」が入力される。 Since the number of facilities, the facility position, the facility type, etc. of the third floor 2 and the fourth floor 2 are the same, the other room photographing used on the fourth floor 2 based on this photographing equipment list E2 An equipment list E3 is created. The other room photographing facility list E3 is different from the photographing facility list E2 only in the floor number, and the other conditions are the same. After creating the other room photographing equipment list E3, the photographing equipment collating unit 54, based on the other room photographing equipment list E3, and the equipment actually photographed on the construction site, as well as the other rooms, as in the fifth embodiment. The target equipment is collated with the photographing equipment list E3. When the facility is photographed at the construction site on the second floor, “completed” is input to the item E33 of the photographing state.
　このように、所定階数のフロア２における撮影済みの写真データに基づいて撮影設備リストＥ２を作成し、この撮影設備リストＥ２に基づいて当該フロア２以外で使用する他室撮影設備リストＥ３を容易に作成することができる。特に、各フロア２における設置設備、設備位置が同一である建物においては、効率的に撮影設備リストを作成することができる。また、第５の実施形態と異なり、図面情報や設備情報がなくても、他室撮影設備リストＥ３を作成することができる。 In this way, the photographing facility list E2 is created based on the photographed photo data on the floor 2 having a predetermined number of floors, and the other-room photographing facility list E3 used outside the floor 2 is easily created based on the photographing facility list E2. Can be created. In particular, in a building where the installation equipment and the equipment position on each floor 2 are the same, a photographing equipment list can be efficiently created. Further, unlike the fifth embodiment, the other room photographing facility list E3 can be created without drawing information or facility information.
　また、工事初期、工事中期、工事終期において、同一の同室撮影設備リストを使用してもよい。例えば、工事初期に作成した同室撮影設備リストに基づいて、工事中期、工事終期における写真撮影を行ってもよい。このように経時における工事状況を撮影する場合に、同一の同室撮影設備リストに基づいて設備を撮影することによって、設備の設置状況を把握するための撮り忘れを防止することができ、工事の進捗に応じた設備の設置状態を確認することができる。 Also, the same room shooting equipment list may be used at the beginning of construction, the middle of construction, and the end of construction. For example, based on the same room photographing equipment list created at the beginning of the construction, photographs may be taken during the middle of construction and at the end of construction. In this way, when shooting the construction status over time, by shooting the equipment based on the same room shooting equipment list, it is possible to prevent forgetting to capture the installation status of the equipment, and the progress of the construction The installation status of equipment according to
