基于图像处理的嵌入式火灾探测系统设计

DSP 器件具有着高速度、高精度的运算能力，而且体积小，使得其应用越来越广泛。系统通过CCD 摄像头，在前加红外滤光片后，由DSP（文中采用TMS320C31）
采集到红外图像去干扰后进行双波段处理，从而进行有无火灾的检测。采用的双波段的
检测手段，可以进行在摄像范围之内的检测，而不受距离的约束。检测方法快捷，准确，增加了系统的实时性和准确性。

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.
