Airborne Experiment of Hyperspectral Remote Sensing and Applications to Ship Detection

Abstract

Recently, shipping maritime traffic has been increasing, and more vessels operating around the ports have led to an increasing number of maritime traffic accidents such as vessel collisions, stranding, and explosions. It is necessary to monitor vessels in real time to prepare for marine accidents and to effectively manage coastal regions. In the event of a marine accident, a rapid search of vessels is needed. Searching for vessels can be conducted by boarding vessels, using helicopters, or using radars around the point of the accident. Most accidents occur under poor weather conditions when winds are strong or waves are high. Such conditions have prevented the rapid detection of vessels. In light of this, highresolution remote sensing methods using satellites or aircraft can contribute to efficient monitoring over a wide area. A hyperspectral sensor has the advantage of extracting more detailed spectral characteristics of objects by hundreds ofnarrow and continuous channels. The hyperspectral sensor can acquire a large amount of spectral information of ground objects, it can be sufficiently utilized in the field of remote vessel detection. In this study, we conducted an airborneexperiment with a hyperspectral camera and conducted a ground experiment to obtain the spectra of the objects. The four objectives of this study were to: (1) perform a hyperspectral airborne experiment to obtain high-resolution images in t
