Abstract

The invention discloses a radar and AIS integrated ship accurate correlation method. The method is characterized in that a radar and an AIS are used for obtaining ship information, the influence of factors such as distance, orientation, navigational speed, course, bow direction, and acceleration on ship correlation is considered, and the matching degree of double-sensor ship target tracks is calculated by establishing a multi-factor fuzzy set model, so as to achieve accurate, stable, and reliable association of ships in a complex multi-target scene. The method comprises the following steps: performing time-space conversion unification on ship data acquired by a double-sensor; establishing a multi-factor fuzzy set, carrying out ship data association for one time, and finding out a reasonable correlation trace point; finally, solving an optimal correlation trace point through secondary correlation. Compared with a traditional correlation method fusing radar and AIS, the method provided by the invention considers six influence factors, not only has the advantages of high accuracy, high error-tolerant rate, and the like, but also is wider in correlation algorithm applicability and higher in reliability.

Description

Technical field [0001] The present invention relates to multi-source information fusion and the field of ship traffic management systems, in particular, a fusion radar and an accurate relationship between ships of AIS. Background technique [0002] With the rapid development of the economy, the increasing information is continuously improved, and the ship traffic management system (Vessel TrafficServices, VTS) requires constant enhancement of system information acquisition and information and ability to process information and application to meet users for security, efficient, convenient VTS. Strong demand. The traffic industry in the ship industry is high, which is used to increase the density of ships. At the same time, it also increases the risk of sea sailing safety. The sea traffic accident has occurred frequently, and the marine environment is more serious, making the on-site environment becomes Uncontrollable. Therefore, in order to effectively solve the above problems, th...
