A large self-driving dataset containing one-minute driving segments with road-camera video, and full localization data.
Dataset collection
Segments were recorded by comma devices installed in real user vehicles. The collection spans several hardware generations (comma two, comma three, comma 3X, and comma four)
Camera systems vary between generations, so native resolution and field of view are not uniform across the dataset.
Each segment includes an offline localization estimate in localizer.safetensors. It fuses raw GNSS measurements, accelerometer and gyroscope data, vehicle motion constraints, and visual feature tracks from the road cameras.
