Abstract

Towards a safe survey of sewer pipe, we have proposed a drifting wireless network camera system with a spherical capsule. In this paper, we report the lighting subsystem for the sewer pipe survey system and a video rotation cancellation mechanism for the system. A strong lighting system is required to observe a crack in an underground pipe because a natural light is not available in the pipe. We clarified that the lighting system is sufficient to observe an evaluation image attached on the inside of an experimental sewer pipe. In addition, the effect of video rotation is reduced by using a gyro sensor introduced in the video rotation cancellation subsystem.
