Based on the structural and temporal features associated with the core region, video recognition system determines whether the video data indicates the presence of fire. | 03-17-2011 |
20110103641 | VIDEO-BASED SYSTEM AND METHOD FOR FIRE DETECTION - A video recognition system detects the presence of fire based on video data provided by one or more video detectors, but suppresses the triggering of an alarm in situations based on the selection of acceptable regions and application of rules associated with each acceptable region. A user defines acceptable regions within the field of view of the video detector and associates with each acceptable region a rule. During processing of video data associated with the field of view, video metrics are calculated and analyzed to detect the presence of fire (e.g., flame or smoke). Prior to triggering an alarm, regions identified as indicative of fire are compared with the user-defined acceptable regions. If there is overlap between the two regions, the rule associated with the acceptable region is applied to determine whether the alarm should be suppressed or triggered. | 05-05-2011 |
20120160525 | VIDEO-BASED FIRE DETECTION AND SUPPRESSION WITH CLOSED-LOOP CONTROL - A closed-loop system employs video analytic outputs in a feedback loop to control the operation of a video-based fire detection system. In particular, video data captured by a video detector is analyzed by a video analytic system to generate outputs identifying regions indicative of fire. These outputs are employed as feedback in a closed-loop control system to orient the camera such that field of the view of the camera is modified to improve the ability of the video analytic system to verify or confirm the presence of fire within a region identified as indicative of fire. In addition, video analytic system may generate outputs identifying the delivery location of a fire suppressant. These outputs are employed as feedback in a closed-loop control system to orient the delivery of suppressant to extinguish the fire. | 06-28-2012 |
