2. Liu, Haolin, et al. Refer-It-in-RGBD: A Bottom-Up Approach for 3D Visual Grounding in RGBD Images. CVPR 2021. [Paper] [Code] [Website]

1. Yang, Zhengyuan, et al. SAT: 2D Semantics Assisted Training for 3D Visual Grounding. ICCV 2021, Oral. [Paper] [Code]

   Personal Notes:

   • Use corresponding 2D image data(ROI feature, label, bbox coordinates and camera pose) to assist 3D grounding.
   • Very solid experiments.

2. Yuan, Zhihao, et al. InstanceRefer: Cooperative Holistic Understanding for Visual Grounding on Point Clouds through Instance Multi-level Contextual Referring . ICCV 2021. [Paper] [Code]

3. Zhao, Lichen, et al. 3DVG-Transformer: Relation modeling for visual grounding on point clouds. ICCV 2021. [Paper] [Code]

   Personal Notes:

   • The novelty of this paper comes from the coordinate-guied contextual aggregation module.

1. He, Dailan, et al. TransRefer3D: Entity-and-Relation Aware Transformer for Fine-Grained 3D Visual Grounding. ACM-MM 2021. [Paper]

1. Huang, Shijia, et al. Multi-View Transformer for 3D Visual Grounding. CVPR 2022. [Paper] [Code]

   Personal Notes:

   • Rotating the center xyz of objects to provide view-related positional information before going through a Tranformer decoder.
   • SOTA results on Nr3D and Sr3D, good reuslts on ScanRefer.

2. Luo, Junyu, et al. 3D-SPS: Single-Stage 3D Visual Grounding via Referred Point Progressive Selection. CVPR 2022, Oral. [Paper] [Code]

   Personal Notes:

   • First single stage work in 3D Visual Grounding !!!
   • The general idea is similar to the iterative shrinking work in 2D Visual Grounding, but the design is more elegant.

3. Cai, Daigang, et al. 3DJCG: A Unified Framework for Joint Dense Captioning and Visual Grounding on 3D Point Clouds. CVPR 2022.

   Dataset Statistics:

   • Natural Reference in 3D (Nr3D)
   • Spatial Reference in 3D (Sr3D)

2. ScanRefer: Chen, Dave Zhenyu, et al. ScanRefer 3D Object Localization in RGB-D Scans Using Natural Language. ECCV 2020. [Paper] [Code] [Website] [Leaderboard]

   Dataset Statistics:

   • On average, there are 13.81 objects, 64.48 descriptions per scene, and 4.67 descriptions per object.
   • Average length of descriptions is 20.27. Frequency of object attributes: spatial language (98.7%), color (74.7%), shape terms (64.9%), and size information (14.2%).
