摘要
提出并实现了一套完整的基于基函数理论的单色相机多通道光谱重构系统。该系统对数码响应值进行了线性校正,提高了光谱重构精度。实验重构光谱的最小均方根误差可以达到0.006 87,色差最小可达到0.02,平均色差只有2.25。
A set of system of multi-channel spectral reconstruction was proposed using basis functions. In order to improve the spectral reconstruction accuracy, the digital response of the system has been processed by linear correction functions. In the experimental results the minimum RMSE of the reconstruction spectrum can reach 0. 006 87, the minimumcolor difference can reach 0.02, the average color difference is only 2.25.
