| 摘 要： | 偏振成像系统主要通过多相机或多通道成像,图像之间存在平移或旋转,偏振解析前必须进行图像配准,否则可能会产生虚假偏振信息。传统的配准算法主要有SIFT和SURF的特征配准算法,但其采用线性高斯金字塔进行多尺度分解来消除噪声和提取特征点,易造成边界模糊和细节丢失。本文从非线性尺度空间构建出发,提出一种基于KAZE特征匹配的偏振图像配准算法。首先,利用Hessian矩阵寻找特征点及其描述向量;然后以最小Hamming距离作为特征点的度量,计算单应矩阵并利用双线性插值实现不同偏振方位角图像之间的配准;最后,以FD1665P相机拍摄的图片为样本进行了实验验证。实验结果表明,本文算法相对基于SIFT和SURF特征点匹配的配准算法,归一化互信息增大、均方根误差减小,配准精度有很大提高。
