  "textContent": "The present invention relates to a navigation assistance device using augmented reality or 3D images and, specifically, to a navigation assistance device which generates augmented reality or 3D images of a ship being operated, other adjacent ships, and the surrounding environment, and shows the images to a navigator to effectively help the navigator navigate safely. In addition, the navigation assistance device of the present invention can use data provided from an automatic identification system(AIS) and an electronic chart information system to display the ship being operated, the other adjacent ships, and the surrounding environment in augmented reality or 3D images even when it is difficult to identify a target due to the poor quality of images captured of the ocean.",
