Abstract:

In Global Navigation Satellite System-denied environments, aircraft visual navigation faces dual challenges posed by significant nighttime heterogenous image discrepancies and feature matching failures caused by large field-of-view rotations. To address these issues, this paper proposes an infrared/satellite cross-domain fast matching localization method for aircraft based on image translation, aiming to enhance nighttime matching and localization performance through image translation and rotational matching strategies. First, we construct HC_CycleGAN, a cross-domain translation model that leverages the integration of Huber loss and spatial attention mechanisms to align satellite and infrared domains. Second, we develop FastPoint, a rapid feature extraction network that integrates a deep variable convolutional layer with residual learning mechanisms to establish an R-DVM computational unit, enhancing both computational efficiency and training stability. Finally, a rotational matching method based on the L-LightGlue dynamic adaptive matching algorithm is proposed. This method combines a geometry-invariant pre-rotation matching strategy for rotational matching correction to determine the aircraft’s position in satellite image based on the inter-image transformation relationships, thereby accomplishing visual localization. Experimental results demonstrate that, compared to existing matching and localization methods, the proposed approach not only improves matching efficiency but also significantly reduces heterogenous image matching errors under rotational conditions.
