TL;DR
One2Any addresses robust 6D pose estimation for unseen objects using only a single RGB-D reference by learning a Reference Object Pose Embedding (ROPE) and predicting a Reference Object Coordinate (ROC) map for a query image. Pose is recovered in the reference camera frame by transforming the query point cloud with the predicted ROC and applying the Umeyama alignment to compute $[\mathbf{R}|\mathbf{t}]$. The approach leverages a latent diffusion-inspired conditioning network with cross-attention (ROPE guiding an OPD U-Net) and a pre-trained VQVAE for query features, enabling fast, single-shot pose estimation without CAD models or multi-view data, while generalizing well to novel objects and occlusions. Quantitative results on Real275, Toyota-Light, LINEMOD, YCB-Video, and other benchmarks show state-of-the-art speed (≈0.09 s/frame) and competitive accuracy, often rivaling multi-view or CAD-based methods. Overall, the method offers scalable, real-time pose estimation for unseen objects with broad applicability to robotics and augmented reality.
Abstract
6D object pose estimation remains challenging for many applications due to dependencies on complete 3D models, multi-view images, or training limited to specific object categories. These requirements make generalization to novel objects difficult for which neither 3D models nor multi-view images may be available. To address this, we propose a novel method One2Any that estimates the relative 6-degrees of freedom (DOF) object pose using only a single reference-single query RGB-D image, without prior knowledge of its 3D model, multi-view data, or category constraints. We treat object pose estimation as an encoding-decoding process, first, we obtain a comprehensive Reference Object Pose Embedding (ROPE) that encodes an object shape, orientation, and texture from a single reference view. Using this embedding, a U-Net-based pose decoding module produces Reference Object Coordinate (ROC) for new views, enabling fast and accurate pose estimation. This simple encoding-decoding framework allows our model to be trained on any pair-wise pose data, enabling large-scale training and demonstrating great scalability. Experiments on multiple benchmark datasets demonstrate that our model generalizes well to novel objects, achieving state-of-the-art accuracy and robustness even rivaling methods that require multi-view or CAD inputs, at a fraction of compute.
