Abstract

During flight, ice may accumulate on the windward side of all components of an aircraft, posing varying degrees of hazards to flight safety. Generally speaking, different types of ice, varying degrees and intensities of ice accumulation, as well as ice accumulation in different parts, are important factors determining the degree of ice accumulation. Hyperspectral images have the advantage of "integrating spectra". This article analyzes the spectra of different ice types based on the organic combination of high-resolution spectral features and two-dimensional geometric features of hyperspectral images, achieving real-time measurement of ice thickness with a measurement error of about 2mm, and obtaining key indicators that affect flight safety.
