基于仿射变换的双波段红外图像配准算法研究

图像配准是图像融合技术中的首要环节,只有经过配准的图像才能够进行融合。虽然双波段红外探测器探测的是同一场景,但是由于光学系统的构造产生了两幅图像,而两幅图像之间却存在了几何位置上的差异,所以在本文中提出一种配准方法。通过点检测方法获取图像的特征点,然后再选取其中两组较为明显的特征点组,再根据仿射变换关系式,确定其中的模型参数,并且对图像进行配准。

Dual Band IR Images Registration Method Based on Affine Transformation

Images registration is one of the crucial steps in the fusion technique of image, image fusion can be done only after registration. The same scene can be taken using dual band IR detector,however, two images come into being for optical system structure in the geometry position which is different. So the article will introduce a method of image registration. The method is to obtain the character dots of images, then choose between two groups of character dots in whole. Based on formula of affine transformation the model-parameter can be determinate and Images registration can be implementing.
