Abstract: A Tele-presence Viewing System (TVS) is usually implemented to augment human operators in tasks that are non-repetitive, unpredictable, or hazardous. One instance is the deployment of an Underwater Robot Vehicle (URV) to navigate along an underwater pipeline for continuous realistic remote observation. However, due to URV positioning errors caused by underwater current, the variations of the size of the pipe image on the monitor can strain the URV pilot visually. It is assumed that an intelligent automatic compensation of the pipe image fluctuation may reduce eye strain and make observation more realistic and comfortable. Hence, the research focuses on the automatic hardware implementation of the two psychological effects of human 3D-vision, such as depth perception and perceptual constancy, so as to semi-automatically maintain the size of the pipe image and its position on the monitor screen due to active control of the camera’s zooming and convergence.
