为了满足导弹跟踪锁定目标过程中实时性要求高这一要求,提出了一种改进的相关匹配算法,并对算法的硬件实现进行了详细讨论,将图像分成4块,每块由一片DSP进行处理,并结合相关算法进行测试。实验结果表明,无论在实时性还是在跟踪有效性方面,该算法都是切实可行的。该系统结构紧凑、可靠性高、实时性强,为图像匹配系统提供了新的高速处理平台。

In order to satisfy the high real-time ability in the process of missile attack, an advanced algorithm of correlation matching is proposed. The hardware realization of this algorithm is also described in detail. Firstly, the image is divided into four parts. Secondly, each part is processed by one DSP. Lastly, debugging is done with correlation matching. The experiment results have shown that the method works excellently in both real-time ability and tracking validity. This system is featured by compact construction, high reliability, and good real-time ability. The system provides a new high-speed processing platform for an image matching system.
