复合材料序列图像的分层次配准
Abstract:
？在复合材料图像三维重构技术中,为了避免直接运用基于特征点的整体配准陷入局部极优,采用分层次的配准方法.首先使用不变矩计算出上下层图像中最相似的颗粒轮廓,然后使用主轴的配准方法完成上下层图像的初步配准,以大幅度减少特征点配准中的优化搜索范围.在计算出轮廓曲线上特征点的基础上,应用最大熵原理和lagrange乘子将点集之间的匹配转化为一个能量函数,再使用最小二乘法计算出使该能量函数值最小的空间变换,得到配准的最优解,从而实现了序列图像的整体精确配准.实验结果表明,本文提出的分层次的配准方法极大地降低了配准过程陷入局部极优的概率,具有较强的鲁棒性和较高的配准精度.
