  • 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.
  • 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.
  • the photographer H can be encouraged to shoot the equipment F4, and forgetting to take the equipment F4 can be prevented.
  • 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. .
  • the photographing equipment list E1 specific equipment can be extracted to create the photographing equipment list E1.
  • the facilities F1, F3, and F4 may be the photographing target facilities.
  • FIG. 17 shows functional blocks of the tablet 3 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.
  • 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.
  • the photographing facility list creation unit 53 creates a photographing facility list E2 based on the facilities F1 to F3 as shown in FIG. .
  • 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.
  • 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.
  • the photographing equipment collating unit 54 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.
  • 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.
  • a photographing equipment list can be efficiently created.
  • the other room photographing facility list E3 can be created without drawing information or facility information.
  • 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.

Abstract

La présente invention concerne le calcul de la distance jusqu'à un sujet photographique pendant la photographie du sujet photographique sans utiliser d'instrument de mesure de distance. Ledit système de gestion photographique de construction comprend une tablette (3) afin d'envoyer des informations de photographie résultant de la photographie d'une installation (F5) installée sur un sol (2) à un ordinateur serveur (5), et permet qu'une CPU de la tablette (3) soustraie une taille L1 de la hauteur L2 du plancher et calcule la distance verticale L3 entre un plafond 2b et la tablette (3), calcule la distance horizontale L4 de la tablette (3) à l'installation (F5) en fonction de la distance verticale L3 et d'un angle d'inclinaison θ, et calcule la position d'installation de l'installation (F5) en fonction de la distance horizontale L4 et d'une orientation γ.
