摘要
从舰载光电系统的图像稳定的要求出发,介绍了稳像技术的种类;分析了电子稳像的原理、算法。提出一种新算法,实现了电子图像稳定。该算法利用最小均方误差和块间运动矢量的空间相关性作为匹配函数,采用四步搜索法计算运动矢量,并和全搜索算法得到的运动矢量进行比较。实验表明,该算法能较好地实现图像序列的稳定。
The importance of image stabilization to warship photoelectricity equipment and varieties of image stabilization technique are introduced. A new algorithm is proposed to realize electronic image stabilization. The algorithm takes minimum square error and spatial correlation as matching function and adapts four-step search algorithm to calculate motion vectors. The result is compared with that of full search algorithm. The experimental results show that this algorithm may produce stabilized series of images.
