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…
TIDY: Thermal Infrared Image Denoising via Wavelet Domain Entropy and Directional Stripe Index
Tai Hyoung Rhee, Dong-Guw Lee, Ayoung Kim
Thermal infrared (TIR) imaging has been a popular choice for field robotics due to its robust perception capability under low light visual degradation, but it suffers from severe s…
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…
