Anti-collision warning system for marine vehicles and anti-collision analysis method

摘要

An anti-collision warning method in an anticollision warning system for marine vehicles is disclosed. The system comprises at least one optical sensor covering at least partially the horizon of the marine vehicle. The method comprises steps of: acquiring from the optical sensor images including a portion of the horizon of the marine vehicle, searching in real time in each image acquired for groups of adjacent pixels according to the light intensity of each pixel of the image, assessing persistence of each group of pixels in successive images acquired, determining groups constituting objects visible on the surface of the sea, according to their persistence, determining position and dimension information of at least one of the visible objects, periodically calculating the evolution of the position and dimension information of the visible object, and assessing a risk of the marine vehicle colliding with the visible object according to the evolution of the position and dimension information of the visible object, a visible object being considered dangerous if there is a risk of the marine vehicle colliding with the visible object.
