Method for automatically identifying illegal dumping based on ship AIS track data

Abstract

The invention discloses a method for automatically identifying illegal dumping based on the ship's AIS track data. Using a piece of ship's AIS track data, the overlapping area with the engineering area and the dumping area is calculated, and each track point of the navigation track of the section is traversed. , Combined with the data of the dumping recorder and the information of the dumping license, it can automatically identify all illegal dumping behaviors and report to the supervision department in a timely manner. It overcomes the shortcomings of the existing technology that supervision is time-consuming and laborious and cannot identify all illegal dumping behaviors, which can effectively reduce illegal dumping behaviors and improve the marine ecological environment.

Description

technical field

[0001] The invention relates to a method for identifying illegal dumping of waste by ships, in particular to a method for automatically identifying illegal dumping of waste based on ship AIS track data. Background technique

[0002] Dumping waste from construction projects into the ocean (dumping) requires a permit in accordance with the law. The contents permitted by the permit include the construction project, the waste dumping unit, the carrier used (waste dumping ship) and the dumping area. The approved waste dumping ship loads waste from the project area and dumps it in the designated dumping area, which is the normal dumping behavior. However, the following violations may exist in the separate dumping of waste ships:

[0003] 1. Unlicensed operation: the dumping ship conducts dumping operations without a license (unlicensed);

[0004] 2. Expired operation: the waste dumping ship still conducts waste dumping operation after the license expires; [00...
