Abstract
analyses (COLLINS et al. 2001). The more accurate the object coordinates of people in the scene are known, the more detailed analyses can be conducted with respect to motion patterns or interactions between tracked people. In this paper we present an approach that generates consistent global tracks of people in non-crowded scenarios. The trajectories are calculated in a common reference frame from observations of multiple surveillance cameras. An important step in our work is the estimation of body height as well as a reliable association of tracks across partly overlapping views. For that purpose, stereoscopic analysis is applied to overlapping parts of images which are either generated randomly while scanning wide areas with several PTZ cam
分析(COLLINS et al. 2001)。场景中人们的物体坐标越准确,就可以对运动模式或被跟踪人之间的互动进行更详细的分析。在本文中,我们提出了一种在非拥挤场景中生成一致的全球人员轨迹的方法。轨迹是在一个共同的参考框架中根据多个监控摄像机的观测计算出来的。我们工作中的一个重要步骤是估计身体高度以及在部分重叠视图中可靠的轨迹关联。为此目的,立体分析应用于图像的重叠部分,这些图像是在用几个PTZ凸轮扫描宽区域时随机生成的
