We train a single model for all objects on each dataset, and based on an architecture of object detection and pose regression.

Object detection: extended FCOS

Pose regression: extended PFA-Pose

Data: PBR

The Main differences from FCOS:

  1. We use stronger augmentations following the best practice in 6D pose estimation

  2. We utilize some mask information for a better sampling of positive signals during training

The main differences from the original PFA-Pose paper:

  • It does not use a detection component, we embed a detection component into it to facilitate the pose regression.

  • It uses exemplars rendered offline for training, which is resource-friendly and efficient during training. For this competition, we replace it with online rendering to achieve better accuracy.

  • It uses only flow from the rendered image to the input. We further use a backward flow from the input to the rendered image for a consistent check to remove more outliers.
