AI Technical Summary

Technical Problem

Existing photoelectric detection equipment is difficult to take into account different spectral bands, and the hierarchical characteristics of the target information obtained are too single, so it is impossible to accurately identify the true and false targets.

Method used

The authenticity and false target identification method based on hyperspectral imaging is adopted. By acquiring hyperspectral images, the images of suspected target areas are extracted, the similarity between their spectrum and the real target image is calculated, and the authenticity of the target is determined.

Benefits of technology

Through hyperspectral imaging technology, the essential characteristics of the target can be analyzed from the spectral level, avoid being confused by false appearance or simple disguise, and achieve accurate identification of true and false goals.

Abstract

The invention provides an authenticity target identification method and device based on hyperspectral imaging. The method comprises the following steps: acquiring a hyperspectral image, and extracting an image of an area where a suspected target is located in the hyperspectral image as an initial target image; wherein the number of the initial target images is at least one; for any initial target image, calculating the similarity between the spectrum of the initial target image and the spectrum of the real target image to obtain a similarity sequence corresponding to the initial target image; and according to the similarity sequence corresponding to the initial target image, determining whether the suspected target in the initial target image is a real target. According to the method, the essential characteristics of the target can be analyzed from the spectrum level on the basis of the spectral information rich in hyperspectrum, the detection target can be effectively highlighted from a complex background, and the authenticity of the target can be more accurately distinguished.
