常规的图像匹配方法数据量大、耗时较长,极大的影响了景象匹配的速度。为了改进景象匹配的速度,通过对景象匹配和多线程技术的研究,利用多线程并行性、快速性的特点,提出一种基于多线程技术的匹配定位方法。采用多线程技术对基准图和实时图像进行实时匹配。经实验证明,多线程对于快速读图和实时匹配有很明显的效果。能够更好的满足导弹景象匹配实时性的要求。

Scene matching location is an important technology in precision control and guidance system. A full-search in large image database is time-consuming and the computation of similarity is complicated. In order to meet requirement that scene matching must get cruise missile position error real-timely. Based on the technology of multithreading for scene matching location, an image matching method was proposed. The proposed method adopts properties of the multithreading technology, which are collateral and useful in reading data and scene matching Experimental results show efficiency of the proposed method for estimating the matching position.
