摘　　要：在摄像机不稳的情况下,为了使摄像机在跟踪过程中输出稳定的视频图像序列,需将电子稳像和数字图像跟踪算法进行结合研究。提出了一种基于电子稳像的数字图像跟踪算法,通过提取图像的特征点及确定对应特征点进行背景补偿、矢量计算和特征跟踪。与单纯稳像不同的是,该算法的处理过程中考虑到了稳像和跟踪参数的互相影响,解决了稳像中运动物体干扰问题和跟踪中背景特征点干扰问题,实验表明:此算法可提取出有效的特征点,保证算法的精度和实时性,对实际应用有重要意义。It is necessary to combine the electronic image stabilization and digital image tracking algorithm to make the camera output stable video image sequence in the tracking process,under the camera works unstably. A digital image tracking algorithm based on the electronic image stabilization was proposed,which picked up the image feature points,determined corresponding feature points,and finished the background compensation,vector calculation and feature tracking. Compared with the traditional image stabilization,the proposed method considered the relationship between the stabile image and tracking parameters,and solved the interference problem of the moving object in the stabile image and background feature points in the tracking process. The results show that the proposed method can pick up the image feature points effectively and make sure the precision and real time property. It speaks volumes for practical application.
