[0017] Hereinafter, embodiments of the present invention will be described by way of example with reference to the drawings.

[0018] As shown in Figure 1, an embodiment of the present invention provides a method for visualizing the behavior of installed objects inside a building in response to a primary external force 2 such as an earthquake or wind. The method for visualizing the behavior of installed objects includes: a building behavior data acquisition step of acquiring building behavior data 4 from the primary external force 2 and data from the building's structural model 3; an installed object data acquisition step of acquiring installed object data 5 including the three-dimensional specifications 10 and material specifications 12 of the installed object; a secondary external force calculation step of calculating a secondary external force 6 acting on the installed object from the building behavior data 4 and the installed object data 5; an installed object behavior data acquisition step of acquiring installed object behavior data 7 from the installed object data 5 and the secondary external force 6; and a visualization step of displaying the installed object behavior data 7 as an image on a display device. The installed object data acquisition step includes: an imaging acquisition step of acquiring an image 8 obtained by photographing the space including the installed object; a segmentation step of segmenting the image 8 to acquire a segmentation image 9; and an installed object three-dimensional specification acquisition step of acquiring the three-dimensional specifications 10 of the installed object from the segmentation image 9. The building behavior data acquisition step includes a primary external force acquisition step for acquiring primary external force 2, a building model acquisition step for acquiring a building model 11, and a structural model acquisition step for acquiring data for a structural model 3 (3D model, skewer model, etc.) for building analysis from the building model 11.

[0019] The method for visualizing the behavior of installed objects in this embodiment is performed by an installed object behavior visualization system 1. The installed object behavior visualization system 1 comprises a computer consisting of a processor and memory, and a display device consisting of a display or projector. The computer is operated by an installed object behavior visualization program. In other words, the installed object behavior visualization program is an installed object behavior visualization program that visualizes the behavior of installed objects inside a building in response to a primary external force 2 such as an earthquake or wind. Specifically, the installed object behavior visualization program causes the computer to execute a building behavior data acquisition step (including a primary external force acquisition step, a building model acquisition step, and a structural model acquisition step), an installed object data acquisition step (including an imaging acquisition step, a segmentation step, and an installed object 3D specification acquisition step), a secondary external force calculation step, an installed object behavior data acquisition step, and a visualization step. In other words, the building behavior data acquisition step, the installed object data acquisition step, the secondary external force calculation step, the installed object behavior data acquisition step, and the visualization step are performed automatically by the computer.

[0020] The method for visualizing the behavior of installed objects may include a specification step in which the user specifies the combination of building behavior data 4 and installed object data 5 to be used when calculating the secondary external force 6 acting on the installed object from building behavior data 4 and installed object data 5 in the secondary external force calculation step.

[0021] The computer includes a building behavior data acquisition unit that performs a building behavior data acquisition step (including a primary external force acquisition unit that performs a primary external force acquisition step, a building model acquisition unit that performs a building model acquisition step, and a structural model acquisition unit that performs a structural model acquisition step), an installation data acquisition unit that performs an installation data acquisition step (including an imaging acquisition unit that performs an imaging acquisition step, a segmentation unit that performs a segmentation step, and an installation 3D specification acquisition unit that acquires 3D specifications 10 of the installation), a secondary external force calculation unit that performs a secondary external force calculation step, an installation behavior data acquisition unit that performs an installation behavior data acquisition step, and a visualization unit that performs a visualization step.

[0022] The installed object may be, for example, a ceiling or a wall. The installed object may also be furniture.

[0023] Installation data 5 is derived from either a BIM model or photographic data. If installation data 5 is derived from a BIM model, it may also be derived from photographic data. If installation data 5 is derived from photographic data, it may also be derived from a BIM model. Note that installation data 5 is not limited to being derived from either a BIM model or photographic data.

[0024] The 3D specifications 10 are information about the 3D shape of the installed object, such as length, width, height, center of gravity, and installation location.

[0025] Material specifications 12 are information about the materials that make up the installed object, such as material type, weight, density, etc.

[0026] Structural model 3 is derived from the BIM model. In other words, building model 11 is a BIM model. However, structural model 3 is not limited to a BIM model; it may also be derived from, for example, a structural analysis model. In other words, building model 11 may be, for example, a structural analysis model.

[0027] The installation data includes the installation structure specifications 13 of the installation. The installation structure specifications 13 are information about the installation structure of the installation, such as the connection method (rigid connection, pin connection, etc.), the ceiling structure method if the installation is on the ceiling (ceiling suspension, ceiling truss, etc.), the fixing method (fixed to the wall, fixed to the floor, etc.), and the coefficient of friction with the floor. The installation data acquisition step includes an installation 3D specification acquisition step that acquires the 3D specifications 10 of the installation from the segmentation image 9.

[0028] The installed object is a floor-mounted object, and the system may be configured to calculate the center of gravity of the floor-mounted object from the installation data 5 of the floor-mounted object, and to determine whether the behavior of the floor-mounted object is toppling over or sliding based on the secondary external force 6 acting on the center of gravity and the frictional force acting between the floor and the bottom surface of the floor-mounted object.

[0029] The installed object is a ceiling material suspended from the upper floor by suspension members. The system may be configured to calculate the center of gravity of the ceiling material from the installed object data 5 of the ceiling material, and then determine whether the behavior of the ceiling material is falling or collapsing based on the secondary external force 6 acting on the center of gravity, the repulsive force acting between the wall material that the ceiling material abuts and the ceiling material, and the tensile force or moment force acting on the suspension members.

[0030] The installed object is a wall-connected object connected to the wall with a connecting member. The system may be configured to calculate the center of gravity of the wall-connected object from the installed object data 5 of the wall-connected object, and to determine whether the behavior of the wall-connected object is falling or collapsing based on the secondary external force 6 acting on the center of gravity, the repulsive force acting between the wall material in contact with the wall-connected object and the wall-connected object, and the tensile force or moment force acting on the connecting member.

[0031] The wall-mounted object is a floor-mounted wall-mounted object installed on the floor. The center of gravity of the floor-mounted wall-mounted object is calculated from the installation data 5 of the floor-mounted wall-mounted object, and the behavior of the floor-mounted wall-mounted object is determined to be either overturning or sliding based on the secondary external force 6 acting on the center of gravity and the frictional force acting between the floor and the bottom surface of the floor-mounted wall-mounted object.

[0032] According to this embodiment, when visualizing the behavior data 7 of installed objects inside a building as an image, the work required to acquire the installation behavior data 7 can be reduced.
