Target Tracking Video Information Acquisition and Transmission Based on SIFT Feature Matching Algorithm

In order to solve the problem of tracking moving object effectively under complex background,a method of target tracking based on SIFT feature matching algorithm was proposed. We realized the target tracking through building the Do G 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.
