Abstract
In this study, we propose a technique for providing stabilized images without roll and for inferring the direction of roll from photographic images, based on the technique for abstracting and creating a consistent horizon line. The chief causes for maritime accidents with boats are "Disregard for weather and marine conditions," "Not keeping sufficient lookout," "Geographical ignorance," and "Insufficient information about waterways." Given this state of affairs, we believe it is important to construct a system that will give ship and boat handlers useful information and aid them in their handling. The focus of the present study is on the "roll" of ships and vessels. In it, we first abstract the horizon line from photographic images. Next, we measure the "roll" in each frame based on positional coordinates of the horizon line in those photographic images. Using the calculated "roll," we then infer the "roll" that follows. While we cannot say based on experimental results that the figures are accurate when it comes to roll volume (the amount of lift), we can make a rough estimate on the timing of rolling. This information is then provided to ship handlers for use in handling.
