SynchronizAR: Instant Synchronization for Spontaneous and Spatial Collaborations in Augmented ...
summary
A system that registers separate SLAM coordinate frames using Ultra-Wideband distance tags and only local pose samples, solving for a 6-DOF rigid transform reduced to rotation about the vertical and bounded translation. Prototype measures distances at ~8.1 Hz, collects 100 samples in <15 s, runs the optimizer in <0.15 s, and yields ~0.15 m translation and ~7.4° rotation error when users sample a >1.6 m area and stay ~4 m apart. no shared map required works across different SLAM SDKs
