FIG. 10 is a diagram showing functional blocks of the AR display unit 40 of this embodiment.
FIG. 11 is an explanatory diagram of AR display by the AR display unit 40 of this embodiment.
FIG. 12 is an explanatory diagram of the follow-up operation in the AR display of this embodiment.

As shown in FIG. 10 , the AR display unit 40 includes a photographed image acquisition unit 41 that acquires a photographed image 120, a motion specifying unit 42 that specifies the motion of moving the position and orientation of the display screen 11D, and a photographed image 120. A superimposed display unit 43 for superimposing and displaying the layout drawing 71 and an adjustment unit 44 for adjusting the display position of the layout drawing 71 are provided.

The captured image acquisition unit 41 acquires the captured image 120 captured by the camera 12 (see FIG. 1). Then, the photographed image acquisition unit 41 sends the acquired information of the photographed image 120 to the action specifying unit 42 and the superimposed display unit 43 . Note that the captured image acquisition unit 41 always acquires the captured image 120 from the camera 12 when the AR display is being performed.

The motion specifying unit 42 specifies the motion of the captured image 120 acquired from the captured image acquiring unit 41 . For example, when the user moves the terminal device 10, the direction of the camera 12 provided in the terminal device 10 changes, so the content of the captured image 120 captured by the camera 12 changes. That is, as the terminal device 10 moves, the captured image 120 also moves. Then, based on the feature points of the image displayed in the captured image 120, the motion specifying unit 42 specifies the amount of movement of the image in the up-down direction, the left-right direction, and the front-rear direction.

In addition, when displaying the 3D equipment image 753, the superimposed display unit 43 of the present embodiment arranges both the 3D equipment image 753 arranged on the inner surface 73N and the 3D equipment image 753 arranged on the outer surface 73G. do.

Also, the superimposed display unit 43 determines the display size of the three-dimensional facility image 753 based on the characteristics of the room space obtained from the captured image 120 . The superimposed display unit 43 extracts, from the captured image 120, features of the room space such as the corners of the room, the horizontal width of the walls, and the vertical width of the walls (the height of the ceiling from the floor). Then, the superimposed display unit 43 aligns the corners of the boundary portion of the three-dimensional boundary image 733 with the corners of the room in the captured image 120, and adjusts the size of the boundary portion such as the walls in the captured image 120 to match the three-dimensional boundary. For example, the size of the boundary portion in the image 733 is matched. In this manner, the superimposed display unit 43 of the present embodiment determines the display position and display size (scale) of the three-dimensional layout drawing 713 on the display screen 11D.

Here, in the building equipment display system 1 of the present embodiment, when the AR display is performed, the user holds the terminal device 10 (display screen 11D) at a predetermined position in the room space of the actual building, The user is requested to start the AR display with the display screen 11D directed in a predetermined direction. The position and orientation of the display screen 11D of the terminal device 10 requested by the user are determined by the position and orientation of the reference image 95 preset by the user in the boundary image 73 .

In the building equipment display system 1, the user moves the position and orientation of the display screen 11D from a state in which the display screen 11D is oriented in a predetermined position and in a predetermined direction as an initial state. Furthermore, in the building facility display system 1, the display of the three-dimensional facility image 753 is changed according to the amount of movement of the display screen 11D from the initial state. As a result, even if the user moves the display screen 11D, the three-dimensional facility image 753 is displayed at the position arranged by the user on the three-dimensional boundary diagram 733 with respect to the photographed image 120 showing the actual building. Display is realized. The AR display will be described in more detail below.

When starting to display the three-dimensional equipment image 753 of the layout drawing 71, the superimposed display unit 43 displays the three-dimensional equipment image 753 according to the position and direction based on the reference image 95 specified by the user when creating the layout drawing. . For example, as shown in FIG. 8(A), when creating a layout diagram, in the center of a two-dimensional layout diagram 712 displaying the inner surface 73N of one wall, a direction from the inner surface 73N side to the outer surface 73G side is displayed. is specified by the user.
