SIFT(Scale Invariant Feature Transform) local feature is chosen because of its scale invariance and the property of accurate key-point localization.The Euclidean distance between different SIFT feature vectors is defined as the measure of similarity to get the pre-matched key-point pairs.The affine transform model is used to realize the registration.In order to get the accurate affine transform parameter,the principal of affine transform error is used to get rid of mismatched key-point pairs from the pre-matched pairs.

该方法选取具有良好尺度、旋转不变性以及精确特征点定位能力的SIFT局部特征,使用其特征向量间的欧氏距离作为相似性度量进行特征点匹配,并依据仿射变换误差准则去除奇异匹配特征点对,采用仿射变换的几何模型,实现了遥感图像的快速自动配准。

3D reconstruction is one of the most challenging problems in computer vision.

According to this characteristic, the search matching method of this diagonal line in this calculation is to regard the main diagonal lines as the superior searched route, discard the elements far from the main diagonal lines and it won't generate matching matrix when actually realized. Just regard the present search point as the start point, search matching elements at the small rectangle from the bottom right, regard the element when found as the new start point, so this can happen repeatedly until the ends of the two strings.

根据这个特点,本算法中的对角线搜索匹配算法以主对角线为优先搜索路径,抛弃了离主搜索路径太远的元素,实际实现时,并不需生成匹配矩阵,只以当前搜索点为起点,向右下方向一个小矩形区域上搜索匹配的元素,找到匹配的元素后即以该元素为新的起点,这样无回溯地重复进行直到两个串的未尾为止。

The method for the point sets selection of point Hough transform and the scan direction for image of searching the point sets were improved by using the geometrical characteristic of the concentric circles:The center of the concentric circles was obtained in the accumulative array firstly,radius was obtained by the mean of distance between the circle center and every edge points afterwards,both the circle center and the edge of the concentric circles were detected accordingly.
