PROBLEM TO BE SOLVED: To improve cost for imaging a wall face of a structure such as a manhole.SOLUTION: A structure imaging system comprises: a cylindrical L-shaped guide 1; a fixing pedestal 2 for fixing the L-shaped guide 1 at an opening part 200 of a manhole 100 so that the L-shaped part of the L-shaped guide 1 is positioned on an inside space side of the manhole 100; a movable structure body 3 which is inserted into the L-shaped guide 1, and movable along a shape of the L-shape; an intromission/sending mechanism device 4 for driving the movable structure body 3; an imaging device 5 attached to a tip end of the movable structure body 3, and imaging a wall face in the manhole 100 by a camera; a first distance sensor 6 for measuring a distance between a camera face of the imaging device 5 as an origin and the wall face in the manhole 100; and a controller 7 for calculating image size of a wall face image imaged by the imaging device 5, by using the distance information with the wall face measured by the first distance sensor 6 and camera parameter information, and displaying the image size with the wall face image on a screen.SELECTED DRAWING: Figure 1 |
