The invention provides a moving ship self-
adaptive tracking method based on space-time
semantic association, which comprises the following steps of: firstly, adaptively determining an area range in which a target possibly appears in a current frame by combining collaborative prediction of ship movement track coherence and appearance feature consistency, greatly reducing a matching search space and reducing calculation overhead, and improving the tracking accuracy of the target in the current frame; then, the detection targets meeting the physical motion law and the target
size change range are screened in the associated area, so that the matching accuracy is remarkably improved, and for missed detection targets caused by cloud layer shielding or
signal weakening, the prediction positions of the missed detection targets are directly adopted for position covering to fill detection blind areas and avoid transient loss, so that the detection accuracy is improved. And finally, by utilizing the characteristics of irregularity,
short life cycle and the like of the broken cloud motion, setting motion variable thresholds of speed, acceleration, course and the like and a continuous
leak detection frame number threshold, and automatically filtering transient pseudo tracks which do not meet stable motion characteristics, thereby greatly reducing the
false alarm rate and improving the accuracy of the
false alarm. Therefore, accurate tracking of a real ship target is still kept in a multi-broken-cloud scene.
