Spectral Reconstruction and Accuracy Appraisal Based on Pseudo Inverse Method

Explained based on the pseudo-inverse method spectral reflectance restructuring principle, and has confirmed the entire restructuring process using the experiment and Matlab, and used the root-mean- square error, the color difference has carried on the appraisal for the spectrum restructuring accuracy and the color chromaticity match accuracy. The experiment proved that the pseudo inverse law restructuring spectrum computation is simple, is convenient, but may not use more digital channels for the spectral reconstruction.
