A Unified Calibration Framework for Coordinate and Kinematic Parameters in Dual-Arm Robots
Tianyu Huang, Bohan Yang, Bin Li +4
Precise collaboration in vision-based dual-arm robot systems requires accurate system calibration. Recent dual-robot calibration methods have achieved strong performance by simulta…
Global Truncated Loss Minimization for Robust and Threshold-Resilient Geometric Estimation
Tianyu Huang, Liangzu Peng, Xinyue Zhang +5
To achieve outlier-robust geometric estimation, robust objective functions are generally employed to mitigate the influence of outliers. The widely used consensus maximization(CM)…
Linearly Solving Robust Rotation Estimation
Yinlong Liu, Tianyu Huang, Zhi-Xin Yang
Rotation estimation plays a fundamental role in computer vision and robot tasks, and extremely robust rotation estimation is significantly useful for safety-critical applications.…
Endo3R: Unified Online Reconstruction from Dynamic Monocular Endoscopic Video
Jiaxin Guo, Wenzhen Dong, Tianyu Huang +5
Reconstructing 3D scenes from monocular surgical videos can enhance surgeon's perception and therefore plays a vital role in various computer-assisted surgery tasks. However, achie…
Physically-Based Photometric Bundle Adjustment in Non-Lambertian Environments
Lei Cheng, Junpeng Hu, Haodong Yan +5
Photometric bundle adjustment (PBA) is widely used in estimating the camera pose and 3D geometry by assuming a Lambertian world. However, the assumption of photometric consistency…
