我们提出了SynchronizAR，这是一种在空间上将多个SLAM设备注册在一起的方法，而无需共享地图或涉及外部跟踪基础设施。SynchronizAR采用基于距离的间接配准，其解决单独SLAM坐标系之间的变换。我们附加一个超宽带~（UWB）的距离测量模块的每一个移动的AR设备，这是能够相对于环境的自我定位。当用户在独立的路径上移动时，我们收集AR设备在其本地帧中的位置以及相应的距离测量。基于注册，我们支持创建一个自发的协作增强现实环境，空间协调用户的交互。我们进行技术评估和用户研究，以调查配准精度和空间协作的可用性。最后，我们展示了使用SynchronizAR的各种协作AR体验。
We present SynchronizAR, an approach to spatially register multiple SLAM devices together without sharing maps or involving external tracking infrastructures. SynchronizAR employs a distance based indirect registration which resolves the transformations between the separate SLAM coordinate systems. We attach an Ultra-Wide Bandwidth~(UWB) based distance measurements module on each of the mobile AR devices which is capable of self-localization with respect to the environment. As users move on independent paths, we collect the positions of the AR devices in their local frames and the corresponding distance measurements. Based on the registration, we support to create a spontaneous collaborative AR environment to spatially coordinate users' interactions. We run both technical evaluation and user studies to investigate the registration accuracy and the usability towards spatial collaborations. Finally, we demonstrate various collaborative AR experience using SynchronizAR.
