摘要
在运动估计技术的基础上提出了一个巡航导弹制导系统中图像匹配问题的解决方案，及其具体实现。针对在制导系统中灰度匹配范围大，实时图和基准图尺寸大，匹配时间要求苛刻等困难，利用视频编码中的运动估计技术和灰度匹配技术之间的相似性，提出了一种基于MAD算法的子块划分匹配算法，并采用运动估计芯片结合高速DSP处理器设计了一套硬件电路。实验证明这种硬件电路能够实时实现灰度匹配。
A scheme based upon motion estimation technology is proposed in this paper for tonal imege matching in guidance system. A sub-block divideings algorithm as well as associated hardware with motion estimation processor and high speed DSP have been developed from MDA in consideration of the similarity of video coding between tonal image matching and motion estimation for overcoming the obstacles of large tonal range, large real time image size and reference size, etc.. It is proved in experiment that the guidance approach is successful.
