The invention belongs to the technical field of water traffic
transportation safety and navigation mark navigation aiding, and mainly relates to a navigation mark anti-collision early warning method based on multi-
sensor fusion, and the method comprises the steps: constructing a multi-
sensor fusion architecture integrating an AIS terminal, a
laser radar and an AI camera, and achieving the omnibearing monitoring and precise recognition of a ship in a navigation channel; a grading response mechanism is adopted, corresponding functions are dynamically started according to the real-
time distance between the ship and the navigation mark, and targeted response from early warning to emergency warning is achieved; a legal evidence chain packaging mechanism is introduced, a unique ID is generated for each early warning event, formatted evidence is stored in an associated mode, and integrity and
traceability of data are ensured; through a
dynamic energy supply strategy, an equipment
operation mode is intelligently adjusted according to a storage
battery voltage threshold value, and continuous and stable work of the
system under the conditions of cloudy and rainy days, night and the like is guaranteed; according to the invention, the accuracy, timeliness and reliability of navigation mark collision early warning information are effectively improved.
