摘　　要：为了有效解决复杂背景情况下运动物体的跟踪问题,提出了一种基于SIFT特征匹配算法的目标跟踪方法。通过构建Do G尺度空间、FIFT特征点检测、特殊点描述子算法、特征点匹配将参考图像和待匹配图形进行SIFT特征点匹配,实现目标跟踪;并通过视频采集模块和无线传输模块将采集的目标图像进行无线传输。实验结果表明:SIFT特征匹配算法可对复杂环境中的目标信息进行有效跟踪。In order to solve the problem of tracking moving object effectively under complex back-ground,a method of target tracking based on SIFT feature matching algorithm was proposed. We realized the target tracking through building the DoG scale space,testing of FIFT feature points,sub-algorithm describing of special point,feature points matching to have SIFT feature points match with the reference images and target graphics. We realized the wireless transmission through the video acquisition module and wireless transmission module Experimental results show that the target information can be tracked effectively with the SIFT algorithm in the video acquisition process under complex environment.
