Researchers have developed StreamRig, a novel framework designed to improve multi-camera odometry for mobile robots and vehicles. This system leverages the geometry of synchronized camera rigs by using a frozen 3D foundation model and a specialized Rig-Resampler to compress features. StreamRig employs causal attention with a key-value cache and a lightweight head for pose regression, with only a fraction of the parameters being trained. The framework achieves lower translation and rotation drift compared to existing monocular streaming and rig-aware offline models across multiple datasets, even when trained solely in simulation and evaluated zero-shot in the real world.
