Abstract

A plant facility apparatus recognition system is provided, which appropriately recognizes a plant facility apparatus even in a plant facility in which a wireless facility and a marker are not able to be installed even when the shape of the plant facility apparatus is different from or has been changed from design data. The plant facility apparatus recognition system that uses a mobile device having a camera to recognize the plant facility apparatus to be subjected to work in the plant facility includes a characteristic length acquirer that acquires information on the pipe as a first characteristic length from an image obtained by causing the camera to image the plant facility apparatus and the pipe existing near the plant facility apparatus, and a characteristic length comparator that compares the first characteristic length with a second characteristic length acquired from the design data and related to the pipe.

Claims (28)

1. An apparatus recognition system that uses a mobile device having a camera to recognize an apparatus to be subjected to work in a facility, comprising:

characteristic length acquirer that acquires information on a pipe as a first characteristic length from an image obtained by using the camera to image the apparatus to be subjected to the work and the pipe existing near the apparatus, wherein

the mobile device is configured to compare the first characteristic length with a second characteristic length acquired from design data and related to the pipe; and

a facility information display section that displays, based on a result of the comparison, information on the pipe and facility information of the apparatus, which is to be subjected to work, wherein

apparatuses are narrowed down to a list of candidate apparatuses including the apparatus based on the information on the pipe.

2. The apparatus recognition system according to claim 1 , wherein

the facility information includes a work instruction detail related to the apparatus to be subjected to the work.

3. The apparatus recognition system according to claim 1 , further comprising:

a database including, as the second characteristic length, a diameter of the pipe within the facility, a length of the pipe, and a distance from a floor or a wall to the pipe.

4. The apparatus recognition system according to claim 3 , wherein

the database further includes, as the second characteristic length, a positional relationship between the apparatus to be subjected to the work and the pipe.

5. The apparatus recognition system according to claim 3 , wherein

the database further includes, as the second characteristic length, a positional relationship between pipes within the facility.

6. The apparatus recognition system according to claim 1 , wherein

the pipe includes one or multiple straight pipe portions and a bent pipe portion,

the apparatus recognition system further comprises a database including, as the second characteristic length, a diameter of each of the one or more straight pipe portions, a length of each of the one or more straight pipe portions, and a distance from a floor or a wall to each of the one or more straight pipe portions.

7. The apparatus recognition system according to claim 1 , further comprising:

an augmented reality (AR) display section that estimates an image captured by the camera from positional information, obtained by identifying the pipe and the apparatus within the facility, of the mobile device and orientation information, obtained by a compass installed in the mobile device, of the mobile device and superimposes and displays a three-dimensional image of the apparatus on the image captured by the camera.

8. The apparatus recognition system according to claim 1 , wherein

the facility information display section displays information on a structural object existing near the mobile device based on positional information, obtained by identifying the pipe and the apparatus within the facility, of the mobile device.

9. The apparatus recognition system according to claim 8 , wherein the apparatus recognition system is also configured to present a movement path of the mobile device by updating, in real time, the positional information, obtained by identifying the pipe and the apparatus within the facility, of the mobile device.

10. The apparatus recognition system according to claim 9 , wherein

the movement path presenting section stores and holds the movement path of the mobile device, estimates an impassable site from the movement path stored and held, and presents a movement path not extending through the impassable site.

11. An apparatus recognition method for using a mobile device having a camera to recognize an apparatus to be subjected to work in a facility, comprising:

acquiring information on a pipe as a first characteristic length from an image obtained by using the camera to image the apparatus to be subjected to the work and the pipe existing near the apparatus;

comparing the first characteristic length with a second characteristic length acquired from design data and related to the pipe; and

displaying, using a facility information display section, and based on a result of the comparison, information on the pipe and facility information of the apparatus, which is to be subjected to work, wherein

apparatuses are narrowed down to a list of candidate apparatuses including the apparatus based on the information on the pipe.
