中文摘要：

为及时发现潜在的安全威胁事件,基于多摄像机视图建立多层平面单应性模型,提出一种拥塞环境多视图行人丢包检测方法。提出了行人丢包事件模型,实现了行人跟踪与启发式丢包事件自动检测,并实现丢包事件检测的自动告警。采用真实公众环境的数据集进行测试,结果表明,本文方法有效解决了行人遮挡问题,丢包事件的自动检测鲁棒性较好。

英文摘要：

For the safety in public transportation and other public areas.a robust and practical method for automatic detection of abandoned luggage from surveillance video in crowded areas is proposed based on multi-camera.Firstly,a video blob detection method is used to detect MVO blobs and SVO blobs at multi-view scene.Then a multi-planar homographic constraint arithmetic is proposed to detect 3D floor location of the objects,and objects can be classified as luggage or man.At last,a heuristic pedestrian event detec...
