By studying the traditional spectral reflectance reconstruction method, and relative power distribution of a lighting source are sparsely decomposed, orthogonal property principal component basis is used to eliminate basis; then data obtained by solving sparse coefficient. After theoretical analysis, based on prior knowledge single-pixel detector carried out software simulation experiment. It can reduce complexity cost system, has certain significance for improvement multispectral image acquisition technology.
