The Embedded System Of Fire Detection On Image-processing Wang Benxi, Guan Hongyun,Fang Jian’an,Du Haitao (Donghua University , College of Information Science,Shanghai,200051 ) Abstract:DSP (Digital Signal Processor) is widely used for its high speed and precise computation .The system uses DSP(TMS320C31) to collect infrared image by CCD (Charge Coupled Device) camera, there is an infrared filter in front of the camera.Then it can detect fire by processing the image using dual-band without limitation of distance. This system is very early and reliably in detecting fires. Key words: filter;dual-band;image-processing;DSP;fire detection
