Calousel: Extrinsic Calibration of Non-overlapping Multi-camera Systems from Pure Rotation
Gwanhyeong Song, Chaehyeon Song, Ayoung Kim
Extrinsic calibration of multi-camera systems with non-overlapping FOVs has been a challenging problem in the robotics literature. Conventional target-based methods impose substant…
Neural Operator-Based Surrogate Model for CFD:Helical Coil Steam Generator in Small Modular Reactor
Minseo Lee, Seongmin Oh, Chaehyeon Song +5
Real-time thermal-hydraulic simulation is essential for digital twin (DT) technology that supports the safe and efficient operation of small modular reactors (SMRs). Computational…
Camera Calibration via Circular Patterns: A Comprehensive Framework with Detection Uncertainty and Unbiased Projection Model
Chaehyeon Song, Dongjae Lee, Jongwoo Lim +1
Camera calibration using planar targets has been widely favored, and two types of control points have been mainly considered as measurements: the corners of the checkerboard and th…
THE-Pose: Topological Prior with Hybrid Graph Fusion for Estimating Category-Level 6D Object Pose
Eunho Lee, Chaehyeon Song, Seunghoon Jeong +1
Category-level object pose estimation requires both global context and local structure to ensure robustness against intra-class variations. However, 3D graph convolution (3D-GC) me…
Camera Agnostic Two-Head Network for Ego-Lane Inference
Chaehyeon Song, Sungho Yoon, Minhyeok Heo +2
Vision-based ego-lane inference using High-Definition (HD) maps is essential in autonomous driving and advanced driver assistance systems. The traditional approach necessitates wel…
