Moving target anti-shielding re-tracking method based on correlation filtering

The invention provides an anti-shielding re-tracking method suitable for a low-speed moving target. According to the tracking method based on correlation filtering, anti-shielding re-tracking is carried out on a low-speed moving target, and three parts of shielding judgment, trajectory prediction and search positioning are added; the shielding judgment is used for judging whether a target is shielded or not, and the track prediction is used for predicting the position of the target under the condition that shielding occurs; the self-adaptive search positioning method is used for performing target search on the basis of the predicted position, the prediction precision of the target position is improved, and it is guaranteed that the reappearing target can be accurately tracked after shielding disappears. The method can be suitable for the condition that the target is completely shielded, can adapt to all types of low-speed targets without pre-training, and can still achieve an excellent anti-shielding re-track
