摘要
运用目标匹配和目标链,对视频中的行人进行跟踪和计数。提出了一种基于Hausdorff距离的快速目标匹配方法,利用快速匹配形成的聚类进行最佳匹配,通过目标运动速度和方向的光滑性度量来建立每个运动目标的"目标链"即运动轨迹,实验结果表明此方法保证了运动跟踪的连续性和行人计数的有效性。
Target matching and target- chain are used to track and count pedestrians in video sequences.The paper proposes a method of fast target matching based on Hausdofff distance, the best matching target is attained by clusters from fast matching, target＇ s velocity and direction measurement of smoothness is used to create targetchain or tracking of moving target. The experimental results show that the method ensure the continuity and effectiveness of the dynamic pedestrians tracking and counting.
