摘要发生火灾与自然灾害都非常难以控制，并且都很容易造成巨大的损失。但是，火灾发生情况是五花八门的，发生的场所也是各有不同。因此，研究开发数字图像系统以实现火焰探测与识别，对于减少火灾所造成的损失有很大意义。80426

    本文研究的数字图像处理系统是在TMS320DM6446平台上设计完成的。这个系统可以实现对目标物体（火焰）进行图像采集、预处理、判断识别以及位置标识。

    本文设计的数字图像处理系统通过CCS软件编写程序。首先通过CCD摄像头采集目标图像，然后通过编程对图像进行预处理，接下来基于YCbCr的颜色模型对采集到目标物体（火焰）进行图像识别，最后在TMS320DM6446平台的DSP内核上对采集的图像进行处理并判断是否有火灾发生并标识，同时在LCD面板上显示。

    在实验过程中，进行了对目标物体（火焰）的探测实验，可以比较精确的探测并标识出火焰范围，取得了较好的实验结果。论文中也展示了在DM6446设备上的实验结果。

Abstract

    Fires and natural disasters are difficult to control。They’re also easy to  cause a  huge loss。However, when the fire happened,the situation is multifarious。 What’s more, where the fire happened is also different。 Therefore, the research of digital image system for flame detection and recognition is significant for reducing the losses    caused by the fire。 

In this thesis, the research of digital image processing system is based on TMS320DM6446 platform。 This system is used to identify the image acquisition,   image processing,image recognition and location identification。

    In this thesis, the code of the digital image processing system is written by CCS software。 First, the CCD camera acquires the image of the target。Then,the system processes the image through the programming。Next ,the model which is based on  YCbCr color processes the image that belongs to the target (fire)。 At last ,on the   platform of TMS320DM6446DSP kernel ,the system processes the collected images to judge whether there is a fire and determine the location of the fire。 At  the same time ,the image is displayed on the LCD panel。

    During the research, the experiments about the target (flame) detection were carried out。 It can almost excellently segmented those fire flames out。 The thesis also shows the experimental results on DM6446 equipment。
