Claim 3:
4. The construction method according to claim 1, further comprising the following step: inputting a visible near-infrared image comprising a target into a visible near-infrared computational spectrometry model on the basis of the final visible near-infrared spectrum dictionary, and calculating a visible near-infrared spectrum corresponding to target pixels,
wherein an input of the visible near-infrared computational spectrometry model is a visible near-infrared image, and the visible near-infrared spectrum corresponding to the target pixels is outputted by using a constraint being that a near neighbor of an element in the target has a similar visible near-infrared spectrum, with reference to the shape of the spectral response curves of the four primary colors, the relative strength of association between the visible near-infrared image and the visible near-infrared spectrum, and spectral prior data of a target background, and by using, as an optimization function, the minimum difference between the sum of corresponding visible near-infrared spectra of an element of a target scene in the final visible near-infrared spectrum dictionary and the sum of corresponding four-band image intensities of the element in the visible near-infrared image, wherein the target is an object to be identified.
