Claim Text:
1. A marine augmented reality system using a moving ceiling transparent display, comprising: a moving ceiling transparent display movably installed on a ceiling of a steering room of a ship; a recognition unit for recognizing a location of the ship and a head direction and a gaze direction of a navigator; a reception unit for receiving information of external image data from an external topographic database (DB) related to external topography depending on the location of the ship and the head direction and the gaze direction of the navigator; a registration unit for adjusting the external image data received by the reception unit so that the external image data is registered in real external images; an output unit for outputting the information of the external image data adjusted by the registration unit at locations of the real external images via the moving ceiling transparent display; a calculation unit for receiving and calculating information about inland waterways, submarine topography, weather, and sea area characteristics, information about a movement speed and a route of the ship, information about movement speeds and routes of surrounding ships, and information about a movement speed and a route of a moving object; and an illuminance sensor for real time sensing of external illuminance, wherein the moving ceiling transparent display moves along the ceiling in the head direction and the gaze direction of the navigator, sensed by the recognition sensor, wherein the moving ceiling transparent display moves along a rail part attached to the ceiling, wherein risk factors of the ship over time are predicted at preset time intervals, and wherein if the illuminance sensor determines that the sensed external illuminance is lower than a preset value, the moving ceiling transparent display displays the real external images using preset templates so as to enhance the visibility.
