Multispectral radiation temperature measurement inversion calculation method based on ISA algorithm

The invention discloses a multispectral radiation temperature measurement inversion calculation method based on an ISA algorithm. The multispectral radiation temperature measurement inversion calculation method comprises the following steps: step 1, obtaining a voltage value of an ith spectral channel corresponding to a sample and a black body; 2, constructing an equation for each spectrum channel, forming an equation set, and establishing a target function; 3, initializing parameters based on an ISA algorithm, calculating a corresponding fitness value according to an objective function value, and determining an optimal colistia position according to the optimal fitness; 4, introducing an adaptive feedback hence and arithmetic crossover operator, and reserving a better individual according to a greedy strategy; 5, judging whether an end condition is met or not; and if yes, outputting a globally optimal solution and a fitness value.
