News

🔥 China3DV Occupancy and Flow Challenge is ongoing! Check challenge doc!

  • 2024/03/20 LightwheelOcc dataset v1.0 released.
  • 2024/03/01 We are hosting CVPR 2024 Autonomous Grand Challenge and China3DV AD Challenge!

Table of Contents

Introduction

  • LightwheelOcc, developed by Lightwheel AI, is a publicly available autonomous driving synthetic dataset. The dataset, which includes 40,000 frames and corresponding ground truth labels for a variety of tasks, is a generalized dataset that navigates a variety of regional terrains, weather patterns, vehicle types, vegetation, and roadway demarcations.
  • Lightwheel AI levers generative AI and simulation to deliver 3D, physically realistic and generalizable synthetic data solutions for autonomous driving and embodied AI. By publishing LightwheelOcc, we aim to advance research in the realms of computer vision, autonomous driving and synthetic data.

Highlights

  • Diverse data distributions, including corner cases and hard scenarios

    • By incorporating complex traffic flows, LightwheelOcc contains diversified simulation of different traffic conditions and driving behaviors. Apart from usual scenarios, the dataset also presents corner cases like small and rare objects on the road, challenging conditions like nighttime and rainy scenes, etc. , enriching real-world data diversity.
