Anti-Collision Warning System for Marine Vehicle and Anti-Collision Analysis Method
First Claim
Patent Images
1. An anti-collision warning system for marine vehicle comprising:
- at least one optical sensor covering at least partially the horizon of the marine vehicle, and supplying images;
an image processor that searches in real time in each image supplied by the optical sensor for groups of adjacent pixels according to the light intensity of each pixel of the image, that assesses the afterglow of each group of pixels in successive images, that determines groups constituting objects visible on the surface of the sea, according to their afterglow, and that determines position information of at least one of the visible objects; and
anti-collision analysis control that periodically calculates the evolution of the position information of at least one visible object, and that assesses a risk of the marine vehicle colliding with the visible object according to the evolution of the position information of the visible object.

Abstract
An anti-collision warning system for marine vehicle includes, an optical sensor covering at least partially the horizon of the marine vehicle, image processing means for extracting in real time from each image position information of objects visible on the surface of the sea, and anti-collision analysis means, which periodically calculate the evolution of the position information of each visible object, and which assess a risk of the marine vehicle colliding with each visible object according to the evolution of the position information of the visible object.

17. An anti-collision warning method in an anti-collision warning system for marine vehicle comprising at least one optical sensor covering at least partially the horizon of the marine vehicle, the method comprising:
-
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 the afterglow of each group of pixels in successive images acquired;
determining groups constituting objects visible on the surface of the sea, according to their afterglow;
determining position information of at least one of the visible objects;
periodically calculating the evolution of the position 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 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. - View Dependent Claims (18, 19, 20, 21, 22)
