METHOD FOR AUTOMATIC DETERMINATION OF ORIENTATION OF SURFACE VESSELS USING OPTOELECTRONIC SYSTEM OF UNMANNED AERIAL VEHICLE Russian patent published in 2024 - IPC G06F18/00 B63B39/00 B63B45/04 

FIELD: pattern recognition using an optoelectronic system of an unmanned aerial vehicle.

SUBSTANCE: method for automatic determination of orientation of surface vessels using an optoelectronic system of an unmanned aerial vehicle includes spatial differentiation of detected objects, skeletonization of contour lines and contouring of ship image with determination of motion from set of successive images. At that, image pixels corresponding to color navigation top, side and stern lights are selected, and by their relative position on the image, determining the orientation, direction of movement and/or class of vessels that are moving or standing still, at that, the unmanned aerial vehicle compares the combination of lights with the combination from the reference book, then makes the corresponding conclusions about the direction of movement, and/or class, and/or state of the object, and detection of lights is performed at traverse angles of optoelectronic system of unmanned aerial vehicle and during movement of unmanned aerial vehicle from right to left and from left to right.

EFFECT: improved surveillance of the surface situation on a large water area of the sea surface in combination with a large number of objects.
