Abstract
A method and a system for building a short-wave, medium-wave and long-wave infrared spectrum dictionary are provided. The method includes: building an infrared three-primary-color chromaticity diagram by using infrared spectrum response curves of an infrared three-primary-color sensor group; performing weighted combination on the infrared spectrum response curves; performing multi-scale discretization on the infrared three-primary-color chromaticity diagram, clustering chromaticity coordinates generated by discretization into different groups, performing weighted combination on the infrared spectrum response curves corresponding to the chromaticity coordinates of each point in the groups, generating a new image-space infrared spectrum, and adding the new image-space infrared spectrum to an initial image-space infrared spectrum dictionary; performing weighted combination on object-space Planck curves associated with three different temperatures to build an object-space Planck spectrum dictionary; and using the final image-space infrared spectrum dictionary and the object-space Planck spectrum dictionary to build the short-wave, medium-wave and long-wave infrared spectrum dictionary.
