📝 摘要（中文）

尽管在机器人抓取的6D物体姿态估计方法上取得了进展，但现有数据集与真实世界抓取任务之间仍存在显著性能差距。现有数据集主要集中在固定位置的桌面抓取场景，无法准确反映厨房环境中的挑战。为此，本文提出KITchen基准，专门用于估计厨房环境中物体的6D姿态。我们收集了约205k张真实RGBD图像，涵盖111种厨房物体，并开发了半自动化标注流程，生成2D物体标签、分割掩膜和6D物体姿态，极大地简化了标注工作。该基准、数据集和标注流程将公开发布。

🔬 方法详解

📄 摘要（原文）

Despite the recent progress on 6D object pose estimation methods for robotic grasping, a substantial performance gap persists between the capabilities of these methods on existing datasets and their efficacy in real-world grasping and mobile manipulation tasks, particularly when robots rely solely on their monocular egocentric field of view (FOV). Existing real-world datasets primarily focus on table-top grasping scenarios, where a robot arm is placed in a fixed position and the objects are centralized within the FOV of fixed external camera(s). Assessing performance on such datasets may not accurately reflect the challenges encountered in everyday grasping and mobile manipulation tasks within kitchen environments such as retrieving objects from higher shelves, sinks, dishwashers, ovens, refrigerators, or microwaves. To address this gap, we present KITchen, a novel benchmark designed specifically for estimating the 6D poses of objects located in diverse positions within kitchen settings. For this purpose, we recorded a comprehensive dataset comprising around 205k real-world RGBD images for 111 kitchen objects captured in two distinct kitchens, utilizing a humanoid robot with its egocentric perspectives. Subsequently, we developed a semi-automated annotation pipeline, to streamline the labeling process of such datasets, resulting in the generation of 2D object labels, 2D object segmentation masks, and 6D object poses with minimal human effort. The benchmark, the dataset, and the annotation pipeline will be publicly available at https://kitchen-dataset.github.io/KITchen.
