CoordRefer: Coordinate-Aware 3D Visual Grounding from Multiview Images
Haijie Li, Jiaxin Zhang, Dave Zhenyu Chen +3
Multiview image-based 3D visual grounding predicts a coordinate frame to define a coordinate system and then regresses a 3D bounding box for localization. However, existing methods…
COB-GS: Clear Object Boundaries in 3DGS Segmentation Based on Boundary-Adaptive Gaussian Splitting
Jiaxin Zhang, Junjun Jiang, Youyu Chen +2
Accurate object segmentation is crucial for high-quality scene understanding in the 3D vision domain. However, 3D segmentation based on 3D Gaussian Splatting (3DGS) struggles with…
VRSO: Visual-Centric Reconstruction for Static Object Annotation
Chenyao Yu, Yingfeng Cai, Jiaxin Zhang +3
As a part of the perception results of intelligent driving systems, static object detection (SOD) in 3D space provides crucial cues for driving environment understanding. With the…
CAMAv2: A Vision-Centric Approach for Static Map Element Annotation
Shiyuan Chen, Jiaxin Zhang, Ruohong Mei +5
The recent development of online static map element (a.k.a. HD map) construction algorithms has raised a vast demand for data with ground truth annotations. However, available publ…
