Method for automatic standardization of remote images based Multitemporal land uses pseudo-invariant plant.

摘要

Automatic method for the radiometric standardization of series of multitemporal remote images of one and the same geographical scene or area, on the basis of vegetative pseudo-invariant soil uses, which comprises: a) the capture of multispectral remote images corresponding to bands selected in the visible or hyperspectral spectrum, b) the digitization or georeferencing of an image, c) analysis of the images captured in a) and selection of parcels using one or two vegetative soil uses, d) the formation of parcels by means of the definition of regions of interest in an image and the transposition thereof to the rest of the image series, e) extraction/determination of the digital values of each spectral band of each image in the reference pseudo-invariant soil use, f) calculation of the correction factors of each band in each image in the series, g) linear conversion of each band of each image using the previously calculated CF, h) formation of the standardized image in its entirety by means of the composition of the bands previously converted linearly.
