TAPFormer: Robust Arbitrary Point Tracking via Transient Asynchronous Fusion of Frames and Events
Jiaxiong Liu, Zhen Tan, Jinpu Zhang +4
Tracking any point (TAP) is a fundamental yet challenging task in computer vision, requiring high precision and long-term motion reasoning. Recent attempts to combine RGB frames an…
TVG-SLAM: Robust Gaussian Splatting SLAM with Tri-view Geometric Constraints
Zhen Tan, Xieyuanli Chen, Lei Feng +4
Recent advances in 3D Gaussian Splatting (3DGS) have enabled RGB-only SLAM systems to achieve high-fidelity scene representation. However, the heavy reliance of existing systems on…
Uncertainty-Aware Normal-Guided Gaussian Splatting for Surface Reconstruction from Sparse Image Sequences
Zhen Tan, Xieyuanli Chen, Jinpu Zhang +2
3D Gaussian Splatting (3DGS) has achieved impressive rendering performance in novel view synthesis. However, its efficacy diminishes considerably in sparse image sequences, where i…
A Plug-and-Play Learning-based IMU Bias Factor for Robust Visual-Inertial Odometry
Yang Yi, Kunqing Wang, Jinpu Zhang +4
Accurate and reliable estimation of biases of low-cost Inertial Measurement Units (IMU) is a key factor to maintain the resilience of Visual-Inertial Odometry (VIO), particularly w…
HGSLoc: 3DGS-based Heuristic Camera Pose Refinement
Zhongyan Niu, Zhen Tan, Jinpu Zhang +2
Visual localization refers to the process of determining camera poses and orientation within a known scene representation. This task is often complicated by factors such as changes…
