Abstract
An apparatus for photographing a pipe without suspension of water supply and a system for controlling the same are disclosed. According to present invention, the interior of the pipe can be photographed by inserting the camera into the pipe and moving and rotating the camera without halting water supply, and information about the movement and rotation of the camera can be produced. A problem of discontinuance of using the whole pipe due to photographing of the interior of the pipe can be prevented. The camera can accurately photograph respective portions in the pipe by precisely moving forward/backward and rotating left/right or up/down. Since information about a practical position in the pipe with respect to the photographed image is provided, a user can accurately grasp a defect-position in the pipe, and can easily control the camera.
