SYSTEM AND METHOD FOR ENSURING THE PERFORMANCE OF A VIDEO-BASED FIRE DETECTION SYSTEM
First Claim
1. A method of initializing a video-based fire detection system to detect the presence of fire, the method comprising:
- acquiring video data comprised of individual frames from a video detector;
calculating background features associated with one or more of the individual frames;
assessing the ability of the video-based fire detection system to detect the presence of fire based on the calculated background features; and
generating an output indicating the ability of video-based fire detection system to detect the presence of fire.

Abstract
A video-based fire detection system receives video data comprised of a plurality of individual frames, and determines based on the video data the ability of the system to detect the presence of fire. The system includes a video recognition system connectable to receive the video data and to calculate one or more background features associated with the video data. Based on the calculated background features, the video recognitions system assesses the ability of the video-based fire detection system to detect the presence of fire. The system includes one or more outputs operably connectable to communicate the results of the assessment made by the video recognitions system.

10. A method of monitoring an ability of a video-based fire detection system to detect the presence of fire, the method comprising:
-
calculating video-quality features associated with individual frames during operation of the video-based fire detection system; detecting video quality degradation that adversely affects the ability of video-based fire detection system to detect the presence of fire based on the calculated video quality features; and generating an output indicating the ability of the video-based fire detection system to detect the presence of fire based on the detected video quality degradation. - View Dependent Claims (11, 12, 13)
