FAULT DETECTOR HAVING VISIBLE RAY CAMERA AND INFRARED RAY CAMERA

摘要

PURPOSE: To surely and quickly detect a fault by combining the visible image system and the thermal image system and using an image processing algorithm in common to compensate draw-backs of both systems. ;CONSTITUTION: A visual monitor image from a visible ray camera 1 is processed by an image processing unit 3, and a fault occurrence location in a supervised image is stored in a memory 21 as fault information together with a fault content such as a fire or smoke breakout and similarly a thermal supervisory image from an infrared ray camera 2 is processed by the image processing unit 3 and a fault occurrence location in a supervised image is stored in the memory 21 as fault information together with a fault content such as a fire or smoke breakout and a CPU 22 is used to discriminate the fault by using a majority decision theory based on the fault alarm obtained from the two different supervised images and when a fault of the same content is sensed in the same location, the fault is detected with high reliability and the visual ray image system and the thermal image system are combined and an image processing algorithm in common to compensate defects of both systems to detect the fault surely and quickly.;COPYRIGHT: (C)1995,JPO
