摘　　要： 利用基于Android操作系统的硬件平台实现了移动电子稳像系统。该系统采用无需人工干预的灰度投影算法,通过行列投影、投影滤波和相关计算获得运动补偿量,根据补偿量对视频进行全局校正。对稳像前后帧的行、列投影及残差图像,分析表明,该系统稳像效果良好,且具有携带方便的特点,易于推广到各类移动终端设备。 A mobile electronic video stabilization system is implemented. It runs on a hardware platform based on Android. This system applies a projection algorithm, which contains three parts： an image gray projection, projection filtering and eorrelation calculation, to compute the motion offset. According to the offset the video is stabilized at last. In experiments, the comparison of row and eohmm projections between the original frame and the stabilized one, and the analysis of residual images show that the system works well and is easy-carried. It is easy to be extended to other mobile terminals.
