摘　　要：为了实现图像自动配准,需要确定初始变换参数,为此提出了图像特征线和图像特征圆的概念。以仿射变换作为图像配准变换模型,由Harris角点检测法确定图像特征点,由图像特征点求取图像特征线和图像特征圆,根据该特征线和特征圆详细推导了图像自动配准初始参数的确定算法。根据以上算法实现了图像自动配准,证明了该算法的有效性。It is necessary to determine initial transform parameters in order to realize automatic＇image registration. Accordingly, the image feature line and image feature circle are put forward. The image feature points are determined through Harris comer point detection method; the image feature line and image feature circle are solved through the image feature points. Based on affine transform model, according to the feature line and feature circle, the algorithm of determining initial automatic image registration parameters is derived. By means of the above algorithm, the automatic image registration is performed, which proves that the algorithm is right.
