| 摘 要： | 运动估计在电子稳像系统中起重要的作用。介绍和比较了几种运动矢量估计算法。为了提高电子稳像系统的性能,提出了在设计电子稳像系统时选取运动矢量估计算法的原则。通过比较应用在航摄图像序列中的投影算法和匹配算法的性能,说明了如何应用运动矢量估计算法的原则。仿真结果表明,根据此原则选取的运动矢量估计算法应用于电子稳像系统是可行的。

Research on estimation algorithm of motion vector of dynamic image sequence |

| Abstract: | Motion estimation plays an important role in electronic image stabilization system. Several typical algorithms of motion vector estimation are introduced and the performances of them are compared. To improve performance of electronic image stabilization system, the principle of choosing motion estimation algorithm in designing system of electronic image stabilization is put forward. Through comparing the performance of projection algorithm and block matching algorithm applied to airborne image sequences, the application of the principle is shown. The simulation results show that the chosen motion estimation algorithm based on the principle applied to electronic image stabilization system is feasible. |
