Abstract: In view of the demand of offshore monitoring and management, the integrated intelligent monitoring of marine traffic is realized by combining the electronic chart, radar monitoring, AIS data and CCTV technology, and integrating the data through the integrated platform. At the same time, a segmentation method of Regional Information Feature Points Extraction(RIFPE) based on location information is proposed. Taking a radar base station as the experimental point, using vector autoregression and factor analysis to model the trajectory threshold of the track segment after the region division, based on the k nearest neighbor algorithm(kNN), the result of the trajectory threshold training is obtained. Finally, the trajectory behavior of the test set is judged.
