Problems solved by technology

[0003] The moving target obtained through this kind of foreground detection does not compare the characteristics between the original tracking target and the re-detected foreground target, and it is difficult to guarantee that it is the original tracking target. Or direction changes, the foreground target obtained at the estimated position is not the original tracking target, so once the tracking is lost, it is difficult to find the original target and continue tracking
[0004] Therefore, the existing technology is difficult to continue tracking when the tracking is lost, and it is easy to lose the original tracking target.

Abstract

The invention discloses a moving target tracking recovery method used for tracking a moving target. The method comprises the steps of: detecting the foregrounds of a current image when a tracked target is lost, obtaining foreground targets, and obtaining a pre-estimated position of the tracked target according to the lost position of the tracked target; when the tracked target is determined to be lost, matching characteristics of candidate targets with characteristics of the tracked target, and obtaining a matching value of each candidate target by means of calculation; and according to the matching values and distances to the pre-estimated position, obtaining the candidate target largest in a weight value, using the candidate target as the original tracked target, and carrying out tracking continuously. The invention further discloses a device corresponding to the method. The method and the device have the advantages that under the condition that the tracked target is lost, matching and pre-estimating are carried out according to the detected foreground target, the foreground target which is most likely to be the original tracked target is obtained, and tracking is continued, so that the tracking continuity is good.

Description

technical field [0001] The invention relates to the field of target tracking, in particular to a method and device for tracking and restoring a moving target. Background technique [0002] The existing method for target tracking is to use a tracking algorithm to track a moving target, and the tracking device moves with the movement of the tracking target to ensure that the tracking target is always located at a specific position in the image. After detecting that the tracking device stops moving If it is judged that the target is lost, a new moving target is obtained through foreground detection, and the estimated position where the tracking target should exist is estimated by using, for example, Kalman filtering, and the foreground target at the estimated position is tracked. [0003] The moving target obtained through this kind of foreground detection does not compare the characteristics between the original tracking target and the re-detected foreground target, and it is ...
