Evaluation of LLLTV and Other Visual Surveillance Techniques for VTS Applications

Abstract

The Coast Guard Vessel Traffic System (VTS) monitors the flow of vessel traffic within certain harbors and waterways. The addition of visual surveillance to the existing radar and radio communication VTS capability had been proposed. To determine the effectiveness of visual surveillance in a harbor environment an ISIT type low light level television (LLLTV) camera system was evaluated at the R and D Center for this application. Also, other alternative visual surveillance systems were briefly considered, including SIT and intensified isocon type LLLTVs, laser-gated TV, and forward looking infrared (FLIR). It was concluded that restricted visibility, limited resolution of TV imagery, and the presence of many intense light sources in the field of view at night makes visual surveillance impractical in a harbor environment by rendering it least useful when surveillance is most needed.
