Claim 9:
10. The construction system according to claim 9, wherein a method of acquiring the corresponding visible near-infrared spectra of the element of the target scene in the final visible near-infrared spectrum dictionary comprises:
classifying the target into a spot target, a multi-pixel target, and a morphological target, the spot target having less than hundreds of pixel points, the multi-pixel target having hundreds to thousands of pixel points, and the morphological target having thousands of pixel points or more;
using one visible near-infrared spectrum to express each pixel in the spot target, and using a single average spectrum curve of visible near-infrared spectra corresponding to the pixels to express the spot target;
using one visible near-infrared spectrum to express each pixel in the multi-pixel target, and using a plurality of visible near-infrared spectra or an average spectrum of the plurality of visible near-infrared spectra to express the multi-pixel target; and
using one visible near-infrared spectrum to express each pixel in the morphological target, and using a plurality of visible near-infrared spectra or an average spectrum of the plurality of visible near-infrared spectra to express the morphological target.
