摘要:

迄今为止,大多数定位系统都是设计用于在具有长期稳定的宏观结构和潜在的小尺度动态的环境中运行的。这些假设允许现有的定位系统产生和利用稳定的地图。然而,在高度动态的工业环境中,这些假设不再有效,并且由于结构的快速大规模变化,跟踪人员的任务更具挑战性。在本文中,我们提出了一种新的定位系统,用于跟踪人在高度动态的工业环境,如建筑工地。该系统利用许多工业环境中现有的CCTV摄像头基础设施以及每个工人手机中的无线电和惯性传感器来准确跟踪多个人。这种多目标多传感器跟踪框架还允许我们的系统使用跨模态训练来处理环境动态。特别是,我们展示了我们的系统如何使用跨模态训练,以便通过利用遮挡图自动跟踪环境变化(即新墙)。此外,我们还展示了如何将这些地图与社会力量结合使用,以准确预测人体运动并提高跟踪精度。我们在建筑工地进行了广泛的真实世界实验,通过跨模态训练和使用社会力量,显示出显着的准确性提高。

英文摘要:

To date, the majority of positioning systems have been designed to operate within environments that have long-term stable macro-structure with potential small-scale dynamics. These assumptions allow the existing positioning systems to produce and utilize stable maps. However, in highly dynamic industrial settings these assumptions are no longer valid and the task of tracking people is more challenging due to the rapid large-scale changes in structure. In this paper we propose a novel positioning system for tracking people in highly dynamic industrial environments, such as construction sites. The proposed system leverages the existing CCTV camera infrastructure found in many industrial settings along with radio and inertial sensors within each worker's mobile phone to accurately track multiple people. This multi-target multi-sensor tracking framework also allows our system to use cross-modality training in order to deal with the environment dynamics. In particular, we show how our system uses cross-modality training in order to automatically keep track environmental changes (i.e. new walls) by utilizing occlusion maps. In addition, we show how these maps can be used in conjunction with social forces to accurately predict human motion and increase the tracking accuracy. We have conducted extensive real-world experiments in a construction site showing significant accuracy improvement via cross-modality training and the use of social forces.
