PROBLEM TO BE SOLVED: To provide a portable terminal device that, when repairing a flotation of an invisible object such as a water supply pipe due to a soil liquefaction phenomenon accompanied by occurrence of a natural disaster, visually displays the water supply pipe in a floating state.SOLUTION: A computation part 10 is configured to compute a plane surface coordinate from holding status information obtained from current position information on a terminal 100 acquired by a position information acquisition part 2 and an angle of view of an imaging part 8, and information on an invisible object in the plane surface coordinate is acquired from a facility information database 1. A virtual image is generated in a virtual image generation part 5, and the amount of correction obtained by touching a distance between a manhole cover 31a leading to a water supply pipe 32 of a desired object from an image displayed in a video image display part 9 and a reference plane surface is configured to be reflected in the virtual image. A generated superimpose-purposed virtual image is configured to be superimposed in the video image display part 9. |
