Image Registration Technique of Hyperspectral Image using Optical Flow Algorithm

摘要

The present invention provides a hyperspectral imaging module 110 for acquiring a hyperspectral image of a river flow velocity measurement site, wherein the hyperspectral image has n band ratios for the same observation object, a hyperspectral imaging module 110; The hyperspectral imaging module 110 receives the hyperspectral images for each of the n band ratios, and performs singularity detection for each of the n hyperspectral images in a predetermined manner, and the position of the point determined as the singularity. a singular point calculation module 120 for storing information in the singular point storage unit 122; and a singular point determination module 130 for determining a final singular point by using the n hyperspectral images composed of first to nth hyperspectral images; Including, the singular point determination module 130, with respect to the position information of the point determined as the singularity in the n-th hyperspectral image, in the first to n-th hyperspectral images, the number of times that the position information is repeatedly determined as a singularity It provides an image matching system that counts and determines the location information as a final singular point in a preset manner using the counted number of times.
