Initial Evaluation of Video-Based Fire Detection Technologies

摘要

Computer processing and image analysis technologies have improved significantly to allow the recent development of effective video-based fire detection systems. Currently, smoke detection algorithms are the most mature. Typically, these systems are being designed and used in large facilities, outdoor locations, and tunnels. However, the technologies are also expected, with some modifications, to be effective in smaller, cluttered compartments found on ships. With the move to use onboard video surveillance, there are advantages in using the video images for other functions, such as fire detection. The video-based recognition technology also has future potential for personnel tracking, flooding detection, and physical damage assessment onboard ship as more event recognition algorithms are developed. This work represents the initial evaluation of video-based detection technologies for improved situations awareness and damage control assessment onboard Navy ships. The test results indicate that the video-based detection systems using smoke alarm algorithms can provide comparable to better fire detection than point-type smoke detectors.
