TriP: A Triangle Puzzle Approach to Robust Translation Averaging
Zhekai Fan, Wanze Li, Jinxin Wang +1
Translation averaging aims to recover camera locations from pairwise relative translation directions and is a fundamental component of global Structure-from-Motion pipelines. The p…
TriDE: Triangle-Consistent Translation Directions for Global Camera Pose Estimation
Francisco Chen, Yiran Wang, Yunpeng Shi
Pairwise translation directions are a key input to camera location estimation in global structure-from-motion. Existing estimators usually process each image pair independently, pr…
Cycle-Sync: Robust Global Camera Pose Estimation through Enhanced Cycle-Consistent Synchronization
Shaohan Li, Yunpeng Shi, Gilad Lerman
We introduce Cycle-Sync, a robust and global framework for estimating camera poses (both rotations and locations). Our core innovation is a location solver that adapts message-pass…
Efficient Detection of Long Consistent Cycles and its Application to Distributed Synchronization
Shaohan Li, Yunpeng Shi, Gilad Lerman
Group synchronization plays a crucial role in global pipelines for Structure from Motion (SfM). Its formulation is nonconvex and it is faced with highly corrupted measurements. Cyc…
