MFOS: Model-Free & One-Shot Object Pose Estimation
This addresses the scalability and practicability issues in robotics and AR/VR by enabling pose estimation for new objects without requiring 3D data at test time.
The paper tackles the problem of object pose estimation in RGB images by introducing a model-free, one-shot approach that generalizes to unseen object categories, achieving state-of-the-art performance on the LINEMOD benchmark.
Existing learning-based methods for object pose estimation in RGB images are mostly model-specific or category based. They lack the capability to generalize to new object categories at test time, hence severely hindering their practicability and scalability. Notably, recent attempts have been made to solve this issue, but they still require accurate 3D data of the object surface at both train and test time. In this paper, we introduce a novel approach that can estimate in a single forward pass the pose of objects never seen during training, given minimum input. In contrast to existing state-of-the-art approaches, which rely on task-specific modules, our proposed model is entirely based on a transformer architecture, which can benefit from recently proposed 3D-geometry general pretraining. We conduct extensive experiments and report state-of-the-art one-shot performance on the challenging LINEMOD benchmark. Finally, extensive ablations allow us to determine good practices with this relatively new type of architecture in the field.
