Vision-Based Panoptic Occupancy Prediction in Urban Environments

This repository contains the implementation of our paper.

Getting Started

• Installation

• Prepare data

• Train

  # Single GPU
  python3 tools/train.py ./configs/sfmocc/sfmocc.py --panoptic
  
  # 8 GPUs
  ./tools/dist_train.sh ./configs/sfmocc/sfmocc.py --panoptic 8

• Evaluation

  # Single GPU
  python3 tools/test.py ./configs/sfmocc/sfmocc.py ./path/to/ckpts.pth --panoptic
  
  # 8 GPUs
  ./tools/dist_test.sh ./configs/sfmocc/sfmocc.py ./path/to/ckpts.pth --panoptic 8

• Visualization

  # Save predictions and images (select scene-id)
  python3 tools/test.py configs/sfmocc/sfmocc.py ./path/to/ckpt.pth --dump_dir=pred_dir --scene xxxx
  
  # Generate video (select scene-id)
  python3 tools/visualization/visual.py pred_dir/scene-xxxx
