Ego-OSCAR: Egocentric Open source Stereo CAptuRe System
Ego-OS, an open-hardware head-mounted capture platform, is presented as a low-cost, reproducible solution for egocentric vision. It combines a global-shutter stereo camera with a 6-axis IMU, Linux SBC, and real-time microcontroller for synchronization. The system includes CAD, firmware, and a dataset of 550 hours of stereo video from 25 contributors, with model-predicted annotations rather than raw video.
The paper introduces Ego-OSCAR, an open-source, low-cost head-mounted capture system for egocentric vision, emphasizing its affordability and reproducibility. It includes stereo cameras, IMU, and synchronization tools, with a dataset of 550 hours of stereo video. The system's calibration and annotation layers are automatically generated, though not human-verified.

We characterize the instrument along sensor fidelity, data utility, and six months of distributed field deployment. Our system is not the highest fidelity egocentric rig; it is the cheapest one a reader of t

arXiv:2608.08285v3 Announce Type: replace-cross Abstract: Egocentric vision has scaled its corpora far faster than its instruments. Calibrated stereo rigidly coupled to a synchronized inertial stream is not new; research-grade headsets deliver it. What does not exist is an open version: those platforms are closed products a third party cannot build or extend, and the consumer cameras used elsewhere are monocular and

We present our system, an open-hardware head-mounted capture platform, at a complete bill of materials under USD 200 in commodity parts and 3D prints. It pairs a hardware-synchronized global-shutter stereo camera with a 6-axis IMU, an embedded Linux SBC for on-device encoding, and a real-time microcontroller that bridges the

Implications for data suppliers
RoboSignal interpretation and collection questions, not statements of buyer demand.
- Confirm the required data type and collection setting with the buyer; this source does not establish a complete collection specification.
- Compare the reported units and scope before using these quantities in a budget. Recording hours, sensor-hours and trajectories are different measures.
- Validate demand and acceptance criteria with a buyer before scaling. Publication, popularity and a research result do not establish a purchase commitment.
