一种SAR图像配准方法及装置
摘要：
本发明公开了一种SAR图像配准方法，对主SAR图像和第一辅SAR图像分别进行特征点提取；对主SAR图像的特征点和第一辅SAR图像的特征点进行全局双向匹配，获得全局地面控制点GCP集合；基于所述获得的全局GCP集合执行第一辅SAR图像到主SAR图像的全局配准，得到全局配准后的第二辅SAR图像；对主SAR图像的特征点和所述第二辅SAR图像的特征点进行局部双向匹配，获得局部GCP集合；基于所述获得的局部GCP集合执行第二辅SAR图像到主SAR图像的局部配准，得到第三辅SAR图像。本发明还公开了一种SAR图像配准装置。
摘要（英）：

The invention discloses a registration method for SAR image, and the method comprises the steps as follows: respectively extracting the character point for the SAR image and the first assistant SAR image; having overall situation bilateral matching operation on the character point of the SAR image and the character point of the first assistant SAR image to obtain the overall ground control point GCP set; overall situation registering from the first assistant SAR image to the main SAR image based on the overall ground control point GCP set to obtain the second assistant SAR image after overall situation registering operation; having partial bilateral matching operation on the character point of the main SAR image and the character point of the second assistant SAR image to obtain the partial GCP set; partially registering from the second assistant SAR image to the main SAR image based on the partial GCP set to obtain the third assistant SAR image. A registration device for SAR image is also disclosed.
