摘　　要：客流量统计系统是图像处理与模式识别技术的综合运用,本文在综合分析了目前广泛采用的系统成像原理和算法特点的基础上.提出了基于主动红外成像的成像系统,该系统克服了以往系统硬件成本和算法复杂性的矛盾,不受光线变化和阴影的影响,CCD摄像机采用垂直安装方式,减少了遮挡情况,并通过神经网络分类算法,能够处理多人挤在一起的情况.系统具有准确性、智能性和鲁棒性.文中还给出了部分实验结果.The passenger flow counting system is the application of image processing and pattern recognition. This paper proposes a system based on the active Near-IR imaging, It can resolve the contradiction between the system＇s cost and the algorithm complexity. It can not be affected by the change of illumination conditions and shadows. To avoid the overlapping condition, the CCD camera is hung from the ceiling with a directly downward view, and the system can deal with the problem of the passing people walks closely each other. This system has high accuracy, intelligence and robusticity. Some test results are given at last,
