Requirements

• Ubuntu 16.04/18.04, CUDA 10.2, python >= 3.6, PyTorch >= 1.7.1, torchvision
• Install detectron2 from source
• sh scripts/install_deps.sh
• Compile the cpp extension for farthest points sampling (fps), optical flow, chamfer distance, and egl renderer:

  sh scripts/compile_all.sh
  

Datasets

Download the 6D pose datasets (LINEMOD, Occluded LINEMOD, YCB-Video) from the BOP website and VOC 2012 for background images.

The structure of datasets folder should look like below:

Train and test

• Our method contains two-stages:

  • Stage I: train the detector, pose estimator, and refiner using PBR synthetic data
  • Stage II: self-supervised training for the pose estimator

• In general, for each part, the training and test commands follow the template: <train/test_script.sh> <config_path> <gpu_ids> (other args)

  • <config_path> can be found at the directory configs/.
  • <gpu_ids> can be 0 or 1 for single-gpu training, or 0,1 for multi-gpu training. We use single-gpu training for all the experiments.

• The trained models can be found at Pan.Baidu, pw: g1x6, or Onedrive.

• Some other resources (including test_bboxes and image_sets) can be found at Pan.Baidu, pw: 8nWC, or Onedrive.
