针对复杂环境下遮挡和视角变化导致目标跟踪漂移问题,提出一种新的目标代谢模型,并结合 LK(Lucas-Kanade)图像配准方法,通过二阶段递进的跟踪方式,实现目标复杂运动状态下的有效跟踪。二阶段分别使用代谢模型中的动态模板和准静态模板进行跟踪,实时更新动态模板的同时,周期性更新准静态模板,利用目标运动信息与模板变化信息之间的关系,实现对目标新旧特征的代谢更新。实验结果表明,该算法有效解决了模型更新带来的跟踪漂移问题,具有较好的鲁棒性和实时性。
針對複雜環境下遮擋和視角變化導緻目標跟蹤漂移問題,提齣一種新的目標代謝模型,併結閤 LK(Lucas-Kanade)圖像配準方法,通過二階段遞進的跟蹤方式,實現目標複雜運動狀態下的有效跟蹤。二階段分彆使用代謝模型中的動態模闆和準靜態模闆進行跟蹤,實時更新動態模闆的同時,週期性更新準靜態模闆,利用目標運動信息與模闆變化信息之間的關繫,實現對目標新舊特徵的代謝更新。實驗結果錶明,該算法有效解決瞭模型更新帶來的跟蹤漂移問題,具有較好的魯棒性和實時性。

Aiming at the problem of target tracking drift caused by occlusion and visual angle change in complex environment,this paper proposes a new target metabolic model,and achieves effective target tracking in the state of complex target motion based on the combination of Lucas-Kanade (LK)image registration algorithm and through a two-stage progressive tracking means.The two-stage progressive tracking mode utilises dynamic template and quasi-static template in metabolic model for target tracking respectively.While the dynamic template is timely updated,the quasi-static template is updated periodically as well.The metabolism update of target from old characteristics to new char-acteristics is realised by the utilisation of the relationship between the target motion information and the template change information.Experi-mental results show that the proposed method effectively solves the tracking sift problem brought about the model update,and has good quali-ties in terms of robustness and real-time property.
