A 5k preview of comma.ai's self-driving dataset containing one-minute driving segments with road-camera video, logs, and full localization data.
## Dataset collection
Segments were recorded by comma devices installed in real user vehicles. The collection spans several hardware generations (comma three, comma 3X, and comma four)

Each segment includes a narrow FOV camera, wide FOV camera, preview thumbnail, log file with various measurements (GNSS, IMU, etc.), frame timing data, and offline localization data.
The offline `localizer.safetensors` is the result of an a fusion of raw GNSS measurements, accelerometer and gyroscope data, vehicle motion constraints, and visual feature tracks from the road cameras providing an accurate localization estimate.
