Anti-Fog Imaging and Ship Positioning and Berthing Method Based on Solar-Blind Ultraviolet Optical Electronic Signal

Abstract

The foggy environment, particularly in the dense fog, would significantly weaken the general optical imaging capability. In such condition, common optical imaging methods could hardly recognize targets and self-position in an effective manner, severely impacting ship berthing operation. Targeted at ship berthing in foggy days and based on zero background interference of solar-blind ultraviolet (UV) optical electronic signal, calibration and imaging positioning method based on solar-blind UV imagers were studied here, achieving three-dimension positioning with high precision. Direct imaging and accurate positioning for assisting in ship berthing could be realized at the same time. In this article, local positioning effect in the foggy environment was evaluated by applying solar-blind UV imaging band. The measurement results verify that accurate positioning could be achieved in the foggy environment by solar-blind UV anti-fog imaging positioning approach to satisfy demands of ship berthing in foggy days.
