  comma.ai presents comma2k19, a dataset of over 33 hours of commute in
California's 280 highway. This means 2019 segments, 1 minute long each, on a
20km section of highway driving between California's San Jose and San
Francisco. The dataset was collected using comma EONs that have sensors similar
to those of any modern smartphone including a road-facing camera, phone GPS,
thermometers and a 9-axis IMU. Additionally, the EON captures raw GNSS
measurements and all CAN data sent by the car with a comma grey panda. Laika,
an open-source GNSS processing library, is also introduced here. Laika produces
40% more accurate positions than the GNSS module used to collect the raw data.
This dataset includes pose (position + orientation) estimates in a global
reference frame of the recording camera. These poses were computed with a
tightly coupled INS/GNSS/Vision optimizer that relies on data processed by
Laika. comma2k19 is ideal for development and validation of tightly coupled
GNSS algorithms and mapping algorithms that work with commodity sensors.
