基于LabVIEW的红外人体目标跟踪

针对红外图像序列信噪比低,缺少边缘及纹理信息,以及人体目标运动自主性强且姿态复杂多变的特点,选用Mean Shift目标跟踪算法,对红外人体目标进行跟踪.针对传统Mean Shift目标跟踪算法不能对尺度变化的红外目标进行有效跟踪的问题,对原有算法进行改进,使用边缘加权直方图与模板中心加权直方图计算Bhattacharyya系数的方式,实现核函数带宽的自适应,并利用界面友好的LabVIEW2011平台进行实现.通过两组实验证明了改进后算法的可行性和有效性.

LabVIEW-based Target Tracking of Inf rared Body

Aiming at low SNR infrared image sequences , the lack of edge and texture information ,as well as inde-pendent and the characteristics of strong human target mo-tion and gesture complex , the paper choosese Mean Shift tracking algorithm to track the target for infrared body .In-frared target can not scale effectively tracking changes in the traditional Mean Shift tracking algorithm ,this paper has im-proved the original Mean Shift algorithm and by using edge-weighted histograms and histogram templates center-weigh-ted way to calculate Bhattacharyya coefficient to achieve nu-clear adaptive function of bandwidth and use friendly inter-face LabVIEW2011 platform to achieve , and has finally proved the feasibility and effectiveness of the improved algo-rithm through two experiments .
