GDRNPP for BOP2022

In the PBR_RGB_MModel setting, all models are trained only using the provided PBR synthetic data. MModel means for each dataset, we trained a separate model for each object.

For detection, we adopted yolox as the detection method. Otherwise, stronger data augmentation and ranger optimizer has been used.

For pose estimation, the difference between our GDRNPP and the CVPR-version GDR-Net mainly includes:

  • Domain Randomization: We used stronger domain randomization operations than the conference version during training.
  • Network Architecture: We used a more powerful backbone Convnext rather than resnet-34, and two mask heads for predicting amodal mask and visible mask separately.
  • Other training details, include learning rate, weight decay, visible threshold, and bounding box type.
