The invention discloses a navigation mark
visual identification and collision early warning method and
system based on
deep learning, and relates to the technical field of intelligent shipping, and the method comprises the steps: collecting a navigation channel monitoring video
stream in real time, and carrying out the preprocessing of a key
image frame; constructing a navigation mark detection model based on an improved Officient Det network, and outputting the position and category of the navigation mark in the key
image frame; the method comprises the following steps: constructing a ship track prediction model through ship historical track data, predicting a short-time track of a ship, calculating the relative position, speed and course angle of the ship and a navigation mark, and constructing a dynamic
collision risk field; and fusing the
visual detection result, the
radar ranging data and the AIS information to obtain a ship
collision risk, and triggering graded early warning based on a preset
risk threshold. According to the method, the improved
deep learning model and the real-time calculation framework are combined, the robustness of navigation mark identification is improved, an efficient collision early warning mechanism is established, and
technical support is provided for intelligent shipping.
