Realization of 3D Stereo Imaging for Underwater Applications

摘要

With the help of flourishing advancement of display technology, the 3D stereoscopic video display is growing especially in entertainment markets. Relying on one single camera, underwater surveillance and operations have been suffering from lacking depth information. This research aims at establishing the 3D stereoscopic vision for inspection and operations in underwater environment. Two sets of parallax images acquired by dual cameras are first combined and interlaced via image processing techniques. Then 3D stereoscopic imaging can be implemented with a 3D television screen accompanied by a pair of polarizing glasses. In order to determine the most appropriate stereo base and underwater viewing distance, a series of observation experiments with human subjects were conducted on examining the 3D effect and the viewing comfortableness. It is highly expected that realization of 3D stereo imaging provides significant enhancement on performance and efficiency of underwater operations and inspection.
