摘　　要：针对当前的火场受困人员搜救系统中,受到高浓度烟雾的限制、定位时间较长、定位不准确的、抗干扰能力较差的弊端,提出一种以图像处理技术配合DSP硬件系统为基础的火场受困人员定位设备的设计方法;通过图像采集设备对火场内的情况实时计算机视觉图像采集,运用DSP图像处理技术,配合干扰下的弱定位算法软件设计,对火场内的干扰信息进行排除,运用以嵌入式技术为基础的处理终端进行火场内受困人员的定位,一旦判断出人员位置,能够进行定位跟踪;实验证明,以图像处理技术和嵌入式技术为基础的火场受困人员定位方法,定位的准确度超过50%,具备实际应用价值。In view of the current fire of trapped workers search and rescue system, the high concentration of the smoke is limit, positio ning time longer, positioning inaccurate, antiinterference ability more bad of disadvantages. Proposed to image processing technolog with DSP hardware system based fire siege personnel positioning device design method. Through the image acquisition device, the situation of fire field real time computer vision image acquisition, the use of DSP image processing technology, combined with the interference of the weak localization algorithm software design, the interference of fire field information is excluded, using embedded technology based processing ter minal for fire trapped within the personnel positioning, once tell staff position, be able to locating and tracking. Experiments show that with image processing technology and embedded technology based fire siege personnel positioning method, the accuracy of positioning more than 50%, has practical application value.
