摘要
针对彩色线阵CCD应用时,出现的成像三色错位问题进行了研究,提出了基于电子稳像技术的CCD成像空间校正方法。与传统方法相比,该方法引入了电子稳像技术的思想,巧妙运用帧间运动的处理手段解决了帧内运动的问题。首先对线阵CCD得到的图像进行彩色图像分离,再通过特征点提取,特征点匹配,错位参数估计,图像补偿,彩色图像合成等过程,最终获得校正后的彩色图像。仿真实验表明,该方法能有效解决三色错位问题,改善图像质量。
On the basis of the research on the phenomenon of imagets three-color dislocation appeared in the application of the color linear arrary CCD, a CCD imaging space correction method based on the technology of electronic image stabilization is proposed. This method contains several key steps including the separation of colour images, the extraction of feature points, the matching of feature points, the estimation of location parameters and the compensation of images. The experimental results show that this method can solve CCD colour disorder and improve the image quality.
