Method for detecting target material by spectral mixture analysis of hyperspectral image

摘要

the invention in a particular region for hyperspectral imaging (hyperspectral image) from the target to the distribution of the target material to the detection method for detecting a target substance according to the present invention, according to a specific area for the in the target material detection method using the second spectral image for detecting the distribution of the target material to the target from the second spectral image, by determining whether the target material in units of pixels, or O with the target material to the materials other than the target material detection, targets for the size to solve the problems of the were many prior art target material detection method in the case that is not detected when small, obtaining the second spectral image for the area to be analyzed, and the image-end member from the acquired second spectral image (image endmember) automatically extracted, here again performed the target spectrum (spectral purity screen by adding the target spectrum) as another end member (spectral unmixing) for the target material, and occupied for the target substance on the basis of the result by being configured obtain a rate to create a distribution diagram for the target material, o a detection sub-pixel (sub-pixel) based on the second spectral mixing analysis of the spectral image formed so that pixels can be substantially to target the target material only correctly detected without being there is provided a method using a target material detection. ;
