Abstract

The invention provides a fishing boat fishing behavior identification method and device. The method comprises the steps: obtaining AIS data, and carrying out the preprocessing of the AIS data, and obtaining the continuous track points of each fishing boat; segmenting the continuous trajectory points of each fishing boat into multiple sections of continuous moving trajectories according to a moving trajectory segmentation algorithm; performing grid mapping on each section of continuous movement track in the plurality of sections of continuous movement tracks to generate a grid movement track; and setting at least two sliding detection windows with different window sizes, and identifying the grid movement track through the at least two sliding detection windows to obtain fishing boat fishing track data and corresponding fishing boat fishing behaviors. The fishing boat fishing behavior is identified based on the AIS data, data counterfeiting can be avoided, the accuracy and timeliness of the fishing boat data are improved, and therefore the accuracy of fishing boat fishing behavior identification is improved; besides, the grid movement track is identified through the at least two sliding detection windows, so that the efficiency and the identification rate of fishing behavior identification of the fishing boat are improved.

Description

Technical field [0001] The present invention relates to fishing boats and fishery resource management and the technical field of fishing prediction analysis, which relates to a method and apparatus for fishing vessel capture behavior. Background technique [0002] Ocean fisheries are an important part of modern agriculture and marine economy, but with the rapid development of China's marine fisheries, the demand for sea products has grown sharply, and the number of marine fishing vessels increases, and the equipment and technology are rapid. China is facing a serious recession of nearby fishery resources, marine environment There are many problems with severe pollution, excessive fishing of some waters. So how to balance the development of modern marine fisheries and secure sustainable marine ecological environment has become an important issue facing the fishery management department. [0003] To solve the above problems, you need to identify fishing boat fishing behaviors. In t...
