Problems solved by technology

Although the accuracy of this method is high, the coverage is extremely narrow, and it cannot be monitored all day long, and the cost is high
Although video surveillance is efficient, it is easily blocked by ships. Most bollards cannot be seen in video surveillance, and video surveillance depends on lighting conditions. Environmental conditions such as night and heavy fog also have a great impact on the monitoring effect, resulting in accuracy lower

Abstract

The invention discloses a method, a system and a readable storage medium for detecting the mooring state of a ship lock bollard. Process the cross-section point data to obtain a cross-sectional contour map; acquire a video image of the mooring part on the bollard captured by the camera; determine the first mooring state of the bollard according to the coordinate data of the cross-sectional contour map determining a second mooring state of the bollard based on the video image; determining a final mooring state of the bollt based on the first mooring state and the second mooring state. The invention combines laser scanning and video identification, and can realize stable, effective, all-time, all-weather, and high-accuracy mooring cable state detection.

Description

technical field [0001] The invention relates to the technical field of shipping management data processing, in particular to a system and a readable storage medium for detecting the bollard bollard state of a ship lock. Background technique [0002] When the ship passes the lock, it needs to enter the lock chamber and wait for release. When the ship enters the lock chamber and arrives at the berthing position, according to the ship lock management regulations, the ship's cable should be tied to the bollard at the ship's berthing position. The main purpose is to fix the ship and prevent the ship from drifting in the water and colliding with other ships, or colliding with the lock gate, which may cause accidents. [0003] The ship lock bollard is a cable fastening device built in the lock chamber lock wall in order to facilitate the fixing of the ship's mooring cables. In ship lock management, how to monitor whether the ship is moored after berthing has become a difficult poi...
