Abstract:

Ship object tracking in remote sensing scenario is of great strategic significance and economic value. How to overcome the influence of ship orientation arbitrariness, close arrangement of offshore ship targets on tracking performance from remote sensing perspective is a challenging task. Multiple-object tracking (MOT) tasks with large aspect ratio such as ships in remote sensing scenarios are studied. An inertial predicting multiple object tracker (IPMOT) is proposed. Firstly, the tracing-by-detection (TBD) paradigm is used to cascade the detector and tracker to effectively avoid the dependence of the training process on the time sequence relationship, and the detector is trained through the open target detection data set to solve the problem of lack of tracking data set. Secondly, addressing the problem of missed detections in the detection phase of the TBD paradigm, which significantly affects tracking performance, an inertial tracking model (ITM) is built. It uses multi-step prediction to track the errors of detector, and uses angle correction to eliminate the impact of angle mutation at the edge. Finally, in order to realize the model training and performance testing of the proposed algorithm, the ship MOT (SMOT) dataset is constructed. The experimental results show that the proposed model improves the performance of MOT accuracy (MOTA) and inverse document frequency (IDF1) indexes by 3.9% and 7.2%, respectively, and the performance of IDs and Frag indexes is significantly improved, with good tracking accuracy and stability.
