某大视场TDICCD相机采用多片TDICCD拼接,多通道输出全色和多光谱遥感图像,为了获得良好的融合和拼接效果,本文提出了一种基于双线性插值的空域互相关配准方法。首先,应用双线性插值算法对多光谱各谱段图像进行放大,得到和全色图像相同大小的多光谱图像。然后,采用空域互相关配准方法对多光谱各谱段图像和全色图像进行配准,并对有重叠像元的两通道图像进行拼接。实验结果表明,本文方法快速,抗噪性和鲁棒性较高,使大视场TDICCD相机多通道遥感图像配准取得了良好的效果。
A large field view TDICCD camera is butted by multi-chip TDICCD
which outputs multispectral(MS) and panchromatic(PAN) images by multi-channel. For the good result of image fusion and mosaic
a registration method based on bilinear interpolation is proposed in the field of spatial correlation. Firstly
the multi-spectral images are magnified by image processing of bilinear interpolation algorithm. The MS image has the same size as the PAN image. Secondly
in the field of spatial correlation
a registration method based on bilinear interpolation is applied on the MS and PAN images
and the two channel images having overlapping pixels are mosaiced. The experimental results show that
the proposed methods have higher rapidity
noise immunity and robustness
which makes the multi-channel registration of the large field view TDICCD camera obtain good results.
