Problems solved by technology

[0004] The existing technology requires the data to have a high sampling rate or a high spatial resolution of the image. However, the remote sensing image sequence obtained by staring satellites in geostationary orbit has the characteristics of few sampling points, low spatial resolution, and short continuous observation time. The traditional target track correlation method is difficult to adapt to the geostationary orbit staring satellite remote sensing image ship target track correlation, which leads to the low correlation accuracy rate of the existing technology, and even cannot achieve effective target track correlation

Abstract

The invention relates to a ship target track association method for a stationary orbit staring satellite remote sensing image, belongs to the technical field of satellite remote sensing, introduces ship automatic identification system information, firstly realizes association of cooperative ship targets, effectively reduces the number of association matching combinations, and then is divided into two association stages to associate non-cooperative targets. The number of matching combinations in the association algorithm is reduced, the ship target track association speed is improved, the influence of medium-low resolution and low frame rate conditions on interrupted track association of the ship target is overcome, association complexity is reduced, association accuracy is improved, finally, the associated interrupted tracks are connected, and ship target track association efficiency is improved; and integrity of ship target situation display is improved.

Description

technical field [0001] The invention relates to the technical field of satellite remote sensing, in particular to a method for associating track of a ship target in a geostationary orbit staring satellite remote sensing image. Background technique [0002] The traditional target track correlation method is aimed at two types of data: one is radar and electronic reconnaissance data, which is characterized by a high data sampling rate and is mainly realized based on target motion characteristics; the other is multi-camera video data , this type of data is characterized by high image spatial resolution, which is mainly realized based on the target image features. [0003] Geostationary orbit staring satellites can stay over a fixed area for a long time, and can quickly adjust the imaging surveillance area as needed. Each observation can obtain the track of the ship target in the relevant sea area. By associating the track of the ship target at different imaging moments , that ...
