<title>Augmented reality for underground pipe inspection and maintenance</title>

Abstract

The University of Surrey is engaged in developing augmented reality systems and teleoperation techniques for enhanced visual analysis and task performance in hostile environments. One particular current project in the UK is addressing the development of stereo vision systems, augmented reality, image processing techniques and specialist robotic vehicles which may be used for the future examination and maintenance of underground sewage pipes. This paper describes the components of the stereo vision and augmented reality system and illustrates some preliminary results of the use of the stereo robotic system mounted on a mobile laboratory vehicle and calibrated using a pin-hole camera model.
