The invention relates to the technical field of marine navigation collision avoidance, in particular to a navigation channel navigation mark collision monitoring method and system based on multi-sensor fusion. The method comprises the following steps: acquiring ship data and water surface data; the navigation direction angle is determined, and the collision risk degree is determined according to the direction angle, the distance between the ship and the navigation mark and the ship speed; determining a collision trend performance index according to the numerical change trend of the collision risk degree; determining an inertial parameter influence index according to the total weight of the ship and the speed of the ship; determining a channel curve influence index according to the flowing direction of the water and the flow velocity of the water; determining the danger avoidance degree by combining the collision trend performance index, the inertial parameter influence index and the channel curve influence index; and carrying out collision early warning on the ship and the navigation mark at the current moment in combination with the collision risk degree and the avoidance risk degree. According to the invention, based on multi-dimensional data analysis, a more accurate navigation mark collision monitoring and early warning result is provided, and the accuracy of navigation mark collision detection is improved.
