通过分析线阵CCD的成像过程,对多光谱CCD相机成像的彩色图像合成方式进行了研究,提出了一种处理方法。通过将各谱段CCD的每个像元信号分别扩展成一个二维像素数组后再进行彩色合成,尝试了利用后期处理的方式校正多光谱相机的配准偏差,改善了相机彩色合成图像的质量。结果表明,这种对CCD信号进行处理的合成方式为空间遥感相机的研制提供了一种技术手段,既能减小配准偏差的影响,同时又能够在不改变相机性能的情况下改善相机输出彩色图像的质量。
By analyzing the imaging process of linear CCD, the multi-spectral CCD camera imaging color image synthesis method is studied, and a processing method is proposed. By expanding each pixel of each CCD into a two-dimensional array of pixels and then carrying out color synthesis, an attempt was made to correct the registration error of the multi-spectrum camera and improve the quality of the camera’s color composite image by means of post-processing . The results show that this method of processing CCD signals provides a technique for the development of space remote sensing cameras, which not only reduces the influence of registration errors but also improves the camera output without changing the camera performance The quality of color images.
