Abstract The present paper is related to the problem of evaluating the spectrum estimation precision of multispectral imaging camera. First, the definition of index of shifting degree(ISD) is given mathematically. Then, a new method, the index of system spectrum estimation shifting degree(ISSD), to evaluate the spectral match ability of multispectral camera is proposed. Both of them use only one index to evaluate the match degree of spectrum curve pairs and the spectrum estimation performance of multispectral camera(system) quantitatively. The feasibility of the newly advanced index is verified via numerical calculation, with the data of 24 typical spectrum pairs and that of 17 intended designed multispectral cameras′ simulation results. The results of numerical calculation of the parameter also indicated that the ISSD may be served as a criterion to classify multispectral cameras with different spectrum estimation performance.
