4D Multi-View Ground Truth
10,000+ hours
Time-synchronised multi-camera capture on the same clip as the egocentric view.
Single-view capture loses the object the moment a hand closes around it. Six to twelve hardware-genlocked cameras surround the work volume, so every moment of a manipulation is observed from at least one unoccluded angle.
Use it as ground truth for validating whatever your own pipeline produces from monocular video — or as the supervision signal for training that pipeline.
This requires rigging and calibrating cameras on site. A contributor network capturing on personal devices cannot produce it.
