LoRA3D: Low-Rank Self-Calibration of 3D Geometric Foundation Models
Ziqi Lu, Heng Yang, Danfei Xu +4
Emerging 3D geometric foundation models, such as DUSt3R, offer a promising approach for in-the-wild 3D vision tasks. However, due to the high-dimensional nature of the problem spac…

3DGS-CD: 3D Gaussian Splatting-based Change Detection for Physical Object Rearrangement
Ziqi Lu, Jianbo Ye, John Leonard
We present 3DGS-CD, the first 3D Gaussian Splatting (3DGS)-based method for detecting physical object rearrangements in 3D scenes. Our approach estimates 3D object-level changes by…

Fast Sparse View Guided NeRF Update for Object Reconfigurations
Ziqi Lu, Jianbo Ye, Xiaohan Fei +4
Neural Radiance Field (NeRF), as an implicit 3D scene representation, lacks inherent ability to accommodate changes made to the initial static scene. If objects are reconfigured, i…
