摘　　要：基于彩色CCD开展棱镜摄谱实验可以克服感光胶片等传统实验法中的一些缺陷,但现有数据处理方法一般采用手工拼接图像和线性插值,比较耗时,且误差较大.本文就此问题编写了摄谱图像处理程序,实现自动寻找谱线、自动拼接,然后根据参考谱线数据通过三次样条插值的方法计算出未知的谱线波长,可以提高效率、减小误差.The prism spectrograph experiment based on color CCD could overcome the defects of traditional methods like those using photographic films,but the current data processing method generally used manual image stitching and linear interpolation,which was quite time-consuming and had a large error.This paper introduced a computer program which realized automatic spectrum searching,image stitching and wavelength calculating of unknown spectrum according to reference spectrum using cubic spline interpolation.It could increase the efficiency and reduce the error.
