Researchers have developed HyperLoop, a novel framework that integrates hyperspectral imaging (HSI) into 3D-SLAM systems for planetary exploration. This approach aims to improve autonomous navigation in visually repetitive or featureless terrains by using spectral signatures to complement RGB data. The study introduced two HSI descriptor families, Bag-of-Spectral-Words (BoSW) and PCA-K VLAD (PCAK-VLAD), and evaluated their effectiveness with existing RGB descriptors on a custom dataset. While the current Red-NIR range of the hyperspectral sensor showed limited improvement over RGB-only methods, the research suggests that incorporating SWIR sensors could significantly enhance future planetary SLAM missions.
