目标定位技术作为信息化战争中实施目标精确打击的前提,是情报保障工作的重要内容。目前主要是采用基于图像配准的方法来实现目标的快速定位,而传统的方法通常都是基于单一特征的图像配准算法,无法保证图像配准结果的可靠性,进而影响目标的定位精度。针对以上问题,提出了一种全局图像配准的目标快速定位方法,该方法采用图像斑点特征和角点特征相结合的配准方法,通过度量两种特征配准结果的相似性来保证目标定位精度。最后利用航空遥感图像数据进行了图像配准性能和目标定位精度实验。实验表明:该方法定位精度高,速度快,能够稳定并快速地完成航空遥感图像的目标定位。
As the precondition of carring out the target precision strike in the information war era, target location is an important part of information security work. At present, the fast target location is achieved for image registration, but the traditional methods are single image feature registration, the registration result can not be assured, and then the target location precision can be effected. To solve these problems,a fast target location method of the global image registration was proposed, the image registration method based on the combination of spot and corner features was adopted, the target location precision can be assured through measuring the similarity of two feature matching. Finally, the experiment of image registration performance and target location precision was realized which use of aerial remote sensing images. Experiments show that the improved methods are steady and the aerial remote sensing images can be located effectively.
