Literature Review Title: Vision-based Robotic Grasping from Object Localization, Pose Estimation, Grasp Detection to Motion Planning: A Review 
Chapter Title:  6D pose estimation Datasets 
1. Abstract of Cited Paper (BIB001):  Estimating the 6D pose of known objects is important for robots to interact with the real world. The problem is challenging due to the variety of objects as well as the complexity of a scene caused by clutter and occlusions between objects. In this work, we introduce PoseCNN, a new Convolutional Neural Network for 6D object pose estimation. PoseCNN estimates the 3D translation of an object by localizing its center in the image and predicting its distance from the camera. The 3D rotation of the object is estimated by regressing to a quaternion representation. We also introduce a novel loss function that enables PoseCNN to handle symmetric objects. In addition, we contribute a large scale video dataset for 6D object pose estimation named the YCB-Video dataset. Our dataset provides accurate 6D poses of 21 objects from the YCB dataset observed in 92 videos with 133,827 frames. We conduct extensive experiments on our YCB-Video dataset and the OccludedLINEMOD dataset to show that PoseCNN is highly robust to occlusions, can handle symmetric objects, and provide accurate pose estimation using only color images as input. When using depth data to further refine the poses, our approach achieves state-of-the-art results on the challenging OccludedLINEMOD dataset. Our code and dataset are available at this https URL.

Literature Review:
There exist various benchmarks for 6D pose estimation. Hodaň et al.  proposed a benchmark for 6D pose estimation of a rigid object from a single RGB-D input image. They introduced the existing datasets such as LM/LM-O dataset  , IC-MI/IC-BIN dataset BIB001 , T-LESS dataset  , RU-APC dataset  and the TUD-L/TYO-L dataset  . Besides, there also exist some other datasets such as the YCB-Video dataset BIB002 , etc. Here we only reviewed some of the widely used datasets in Table 9 and their volumes are presented.
