HYPERSPECTRAL WAVEBAND EXTRACTION METHOD BASED ON OPTIMAL INDEX FACTOR-CORRELATION COEFFICIENT METHOD

摘要

A hyperspectral waveband extraction method based on an optimum index factor-correlation coefficient method, comprising the following steps: step A: conducting processing such as sorting and organization of original hyperspectral data; step B: conducting optimum index factor calculation after sorting and organizing the original hyperspectral data; step C: calculating the maximum 3 waveband correlation coefficients; step D: selecting a hyperspectral waveband based on the optimum index factor calculation, correlation calculation and weight-quotient index calculation of the data. The method overcomes the defects of a traditional hyperspectral data waveband selection method of being susceptible to interference from other factors when inverting a target requirement using a single waveband, and lacking a relation between each waveband and a target when using a multiband.
