使用仿射不变特征的遥感图像自动配准

Automatic Registration of Remote Sensing Images Using Affine Invariant Features

提出一种仿射不变特征的构造方法对航空图像序列进行全自动配准。仿射不变特征基于图像尺度空间和二阶矩矩阵构建,配准使用金字塔方法和距离度量的加速算法进行,借助配准概率模型检验,保证配准可靠性。实验结果证明,使用仿射不变特征能在无定位信息的情况下有效完成航空图像序列的自动配准。

This paper proposes an affine invariant feature construction method, and fulfills automatic registration of aerial image sequence using this feature. Affine invariant feature is constructed based on scale space and second moment matrix, image registration is performed using pyramid method and distance calculation acceleration, and reliability is ensured by registration probability model. Experimental result shows without any position information automatic registration of aerial image sequence is performed efficiently using affine invariant features.
