Bridge area water area ship collision risk detection method and device

Abstract

The invention discloses a bridge area water area ship collision risk detection method and device, and the method comprises the steps: obtaining original AIS data of a bridge area water area, carrying out the preprocessing of the original AIS data, and obtaining a bridge area water area range and ship navigation trajectory data; obtaining a trajectory density map according to the bridge area water area range and the ship navigation trajectory data; determining channel boundary points and channel separation points according to the trajectory density map; and according to the channel boundary point and the channel separation point, obtaining a channel boundary of a bridge water area, and according to the channel boundary and a navigation trajectory of a to-be-detected ship, determining whether there is a collision risk between the to-be-detected ship and the channel boundary. According to the method, the channel boundary is accurately identified, whether the collision risk exists between the to-be-detected ship and the channel boundary or not is judged, detection parameters are fewer, easier to explain and more accurate, the probability of collision accidents can be reduced from the source, and casualties and property losses caused by ship and bridge collision are avoided.

Description

technical field [0001] The present invention relates to the technical field of water traffic management, and in particular, to a method, device and computer-readable storage medium for detecting collision risk of ships in bridge area waters. Background technique [0002] Inland waterway shipping is an important part of my country's comprehensive transportation system and plays an indispensable role in my country's economic development. With the development of modern cities, the number of bridges continues to increase, and there are more and more bridge collapse events caused by ship-bridge collisions. Bridge accidents have a huge impact on life safety, economic benefits and social effects. Therefore, how to reduce the loss caused by ship-bridge collision has attracted extensive attention at home and abroad. [0003] In the prior art, the method for preventing ship-bridge collision is mainly to provide effective protection for the bridge from the perspective of installing an...
