摘要:

基于点云的方法已经在自动驾驶中的3D目标检测等领域产生了有希望的结果。然而,大多数最近的点云工作集中在单个深度传感器数据,而较少的工作已经做了室内监测应用,如医院手术室监测或室内监控。在这些场景中,通常使用多个相机来解决遮挡问题。我们提出了一个端到端的多人3D姿态估计网络,点R-CNN,使用多个点云源。我们进行了广泛的实验,以模拟具有挑战性的现实世界的情况下,如个别相机故障,各种目标外观,和复杂的混乱场景与CMU全景数据集和MVOR手术室数据集。与大多数以前的方法,试图通过建立复杂的融合模型,这往往会导致泛化能力差,使用多个传感器的信息,我们利用连接点云的效率,在输入级融合的信息。与此同时,我们展示了我们的端到端网络大大优于级联的最先进的模型。

英文摘要:

Point cloud based methods have produced promising results in areas such as 3D object detection in autonomous driving. However, most of the recent point cloud work focuses on single depth sensor data, whereas less work has been done on indoor monitoring applications, such as operation room monitoring in hospitals or indoor surveillance. In these scenarios multiple cameras are often used to tackle occlusion problems. We propose an end-to-end multi-person 3D pose estimation network, Point R-CNN, using multiple point cloud sources. We conduct extensive experiments to simulate challenging real world cases, such as individual camera failures, various target appearances, and complex cluttered scenes with the CMU panoptic dataset and the MVOR operation room dataset. Unlike most of the previous methods that attempt to use multiple sensor information by building complex fusion models, which often lead to poor generalization, we take advantage of the efficiency of concatenating point clouds to fuse the information at the input level. In the meantime, we show our end-to-end network greatly outperforms cascaded state-of-the-art models.
