Abstract

The invention discloses a spectrum interval rapid selection method and system, belongs to the technical field of near infrared spectrum analysis, and solves the problems of low spectrum interval selection speed and low precision when the number of spectrum partitions is large in the prior art. According to the spectral interval rapid selection method and system, the spectrum is divided into N spectrum intervals which are randomly encoded, a family is formed by using the N encoded spectrum intervals and a group is formed by using m families; the target function value of each family in the groupis obtained, variation on the spectral interval code of each family is performed according to the size of the target function value, the offspring of the corresponding family is determined accordingto the target function values before and after family variation, and a new group is formed by the offspring of each family; and the new group is repeatedly formed until a set variation frequency is reached to obtain an optimal spectrum interval code, thereby obtaining the optimal spectrum interval. The speed and the precision of spectral interval selection are improved when the number of spectralpartitions is large.
