Highlights

  • ๐Ÿš˜ Planning-oriented philosophy: UniAD is a Unified Autonomous Driving algorithm framework following a planning-oriented philosophy. Instead of standalone modular design and multi-task learning, we cast a series of tasks, including perception, prediction and planning tasks hierarchically.
  • ๐Ÿ† SOTA performance: All tasks within UniAD achieve SOTA performance, especially prediction and planning (motion: 0.71m minADE, occ: 63.4% IoU, planning: 0.31% avg.Col)

News

  • Paper Title Change: To avoid confusion with the "goal-point" navigation in Robotics, we change the title from "Goal-oriented" to "Planning-oriented" suggested by Reviewers. Thank you!

  • [2023/06/12] Bugfix [Ref: #21]: Previously, the performance of the stage1 model (track_map) could not be replicated when trained from scratch, due to mistakenly adding loss_past_traj and freezing img_neck and BN. By removing loss_past_traj and unfreezing img_neck and BN in training, the reported results could be reproduced (AMOTA: 0.393, stage1_train_log).

  • [2023/04/18] New feature: You can replace BEVFormer with other BEV Encoding methods, e.g., LSS, as long as you provide the bev_embed and bev_pos in track_train and track_inference. Make sure your bevs and ours are of the same shape.

  • [2023/04/18] Base-model checkpoints are released.

  • [2023/03/29] Code & model initial release v1.0

  • [2023/03/21] ๐Ÿš€๐Ÿš€ UniAD is accepted by CVPR 2023, as an Award Candidate (12 out of 2360 accepted papers)!

  • [2022/12/21] UniAD paper is available on arXiv.

Getting Started

Results and Pre-trained Models

UniAD is trained in two stages. Pretrained checkpoints of both stages will be released and the results of each model are listed in the following tables.

Stage1: Perception training

We first train the perception modules (i.e., track and map) to obtain a stable weight initlization for the next stage. BEV features are aggregated with 5 frames (queue_length = 5).

Method Encoder Tracking
AMOTA		 Mapping
IoU-lane		 config Download
UniAD-B R101 0.390 0.297 base-stage1 base-stage1

Stage2: End-to-end training

We optimize all task modules together, including track, map, motion, occupancy and planning. BEV features are aggregated with 3 frames (queue_length = 3).

Checkpoint Usage

  • Download the checkpoints you need into UniAD/ckpts/ directory.
  • You can evaluate these checkpoints to reproduce the results, following the evaluation section in TRAIN_EVAL.md.
  • You can also initialize your own model with the provided weights. Change the load_from field to path/of/ckpt in the config and follow the train section in TRAIN_EVAL.md to start training.

Model Structure

The overall pipeline of UniAD is controlled by uniad_e2e.py which coordinates all the task modules in UniAD/projects/mmdet3d_plugin/uniad/dense_heads. If you are interested in the implementation of a specific task module, please refer to its corresponding file, e.g., motion_head.

TODO List

  • All configs & checkpoints [Soon]
  • Upgrade the implementation of MapFormer from Panoptic SegFormer to TopoNet, which features the vectorized map representations and topology reasoning.
  • Support larger batch size
  • [Long-term] Improve flexibility for future extensions
  • Fix bug: Unable to reproduce the results of stage1 track-map model when training from scratch. [Ref: #21]
  • Visualization codes
  • Separating BEV encoder and tracking module
  • Base-model configs & checkpoints
  • Code initialization
