Specifically, we perform grasp pose transfer across a category of objects based on their shape correspondences and propose a grasp pose refinement module to further fine-tune grasp pose of grippers so ...
However, most of existing methods require exact 3D object models available beforehand or a large amount of grasp annotations for training. ...
For convenience, we randomly select one instance for each category from the existing large-scale grasp dataset ACRONYM [7] with pose annotations. ...
