Lyft Dataset SDK

Welcome to the devkit for the Lyft Level 5 AV dataset! This devkit shall help you to visualise and explore our dataset.

Release Notes

This devkit is based on a version of the nuScenes devkit.

Getting Started

Installation

You can use pip to install lyft-dataset-sdk:

pip install -U lyft_dataset_sdk

If you want to get the latest version of the code before it is released on PyPI you can install the library from GitHub:

pip install -U git+https://github.com/lyft/nuscenes-devkit

Dataset Download

Go to https://level5.lyft.com/dataset/ to download the Lyft Level 5 AV Dataset.

The dataset is also availible as a part of the Lyft 3D Object Detection for Autonomous Vehicles Challenge.

Utils for converting LEVEL5 data into Kitti format

Simply run
python -m lyft_dataset_sdk.utils.export_kitti nuscenes_gt_to_kitti --lyft_dataroot ${DS_PTH} --table_folder ${TBL_PTH}
for converting data.
See help ( python -m lyft_dataset_sdk.utils.export_kitti nuscenes_gt_to_kitti --help ) for more information.
You can draw results after converting with utils:
python -m lyft_dataset_sdk.utils.export_kitti render_kitti

Tutorial and Reference Model

Check out the tutorial and reference model README.

Dataset structure

The dataset contains of json files:

  1. scene.json - 25-45 seconds snippet of a car's journey.
  2. sample.json - An annotated snapshot of a scene at a particular timestamp.
  3. sample_data.json - Data collected from a particular sensor.
  4. sample_annotation.json - An annotated instance of an object within our interest.
  5. instance.json - Enumeration of all object instance we observed.
  6. category.json - Taxonomy of object categories (e.g. vehicle, human).
  7. attribute.json - Property of an instance that can change while the category remains the same.
  8. visibility.json - (currently not used)
  9. sensor.json - A specific sensor type.
  10. calibrated_sensor.json - Definition of a particular sensor as calibrated on a particular vehicle.
  11. ego_pose.json - Ego vehicle poses at a particular timestamp.
  12. log.json - Log information from which the data was extracted.
  13. map.json - Map data that is stored as binary semantic masks from a top-down view.

With the schema.
