• Abstract: In this paper, we present a CAD model-based zero-shot pose estimation pipeline called ZeroPose. Existing pose estimation methods remain to require expensive training when applied to an unseen object, which greatly hinders their scalability in the practical application of industry. In contrast, the proposed method enables the accurate estimation of pose parameters for previously unseen objects without the need for training. Specifically, we design a two-step pipeline consisting of CAD model-based zero-shot instance segmentation and a zero-shot pose estimator. For the first step, there is a simple but effective way to leverage CAD models and visual foundation models SAM and Imagebind to segment the interest unseen object at the instance level. For the second step, we based on the intensive geometric information in the CAD model of the rigid object to propose a lightweight hierarchical geometric structure matching mechanism achieving zero-shot pose estimation. Extensive experimental results on the seven core datasets on the BOP challenge show that the proposed zero-shot instance segmentation methods achieve comparable performance with supervised MaskRCNN and the zero-shot pose estimation results outperform the SOTA pose estimators with better efficiency.

  Current techniques heavily rely on a reference 3D object, limiting their generalizability and making it expensive to expand to new object categories. This paper proposes ShapeShift, a superquadric-based framework for object pose estimation that predicts the object's pose relative to a primitive shape which is fitted to the object.

  We propose an approach that takes a single image of a new object as input and predicts the relative pose of this object in new images without prior knowledge of the object's 3D model. We achieve this by training a model to directly predict discriminative embeddings for viewpoints surrounding the object. This prediction is done using a simple U-Net architecture with attention and conditioned on the desired pose, which yields extremely fast inference.

  MegaPose is a method to estimate the 6D pose of novel objects, that is, objects unseen during training. We present a 6D pose refiner based on a render&compare strategy which can be applied to novel objects. Second, we introduce a novel approach for coarse pose estimation which leverages a network trained to classify whether the pose error between a synthetic rendering and an observed image of the same object can be corrected by the refiner.
