一种遥感图像的配准方法

综合利用、处理多源遥感图像数据理论与方法的需求越来越多,其中配准是使用遥感图像中重要的预处理步骤.SIFT算法首先在尺度空间进行特征检测,并确定特征点的位置和特征点所处的尺度,然后使用特征点邻域梯度的主方向作为该特征点的方向特征.然后使用RANSAC算法剔除误匹配点,使用最小二乘法拟合图像的变换函数.试验证明了SIFT...

A Registration Method of Remote Sensing Image

Comprehensive utilization and processing multi-source remote sensing image data of the theory and method of growing demand,including registration is using remote sensing images of important preprocessing step.SIFT algorithm firstly in scale space for feature detection,and determine the feature point position and feature point in scale,then use the feature point neighborhood gradient of principal direction as the feature points directional characteristics.Then use RANSAC algorithm eliminate mismatch point,us...
