基于尺度不变特征的目标识别与跟踪方法

摘要

针对复杂电磁环境下目标实时识别追踪的复杂性和多样性,利用图像配准技术提出了一种基于尺度不变特征的目标识别与跟踪方法,有效地反映了目标图像的特征分布,提高了跟踪与识别系统的可靠性.实验表明,当目标进行较大角度改变和背景发生剧烈变化时,该方法能有效减小目标跟踪误差,精确识别目标位置,提高目标跟踪精度.%To the complexity and multiformity of the target real-time recognition and tacking in the complex electromagnetic environment,this paper proposed the target recognition and tacking method based on scale invariant feature in use of image registration techniques,which reflected the character distribution of the target image better,enhanced the performance and reliability of the target recognition and tracking system.The experimental result shows that the method could drop off the matching error,recognize the target location accurately and improve the accuracy of target tracking when the target angle or background has acutely changed.
