HETA++: Global Structure-from-Motion with Hybrid Explicit Translation Averaging
Peilin Tao, Hainan Cui, Mengqi Rong +1
Global Structure-from-Motion (SfM) offers advantages over incremental methods in terms of efficiency and error distribution. However, the task of translation averaging remains chal…
MWorld: A Multi-view Multimodal Driving World Model for Interactive Object Manipulation and Minute-long Streaming
Ke Cheng, Hanqiao Ye, Lei Shi +8
Driving-world generation has emerged as a core capability for scalable autonomous-driving simulation, yet existing methods remain limited in object-level controllability and long-h…
Anchor3R: Streaming 3D Reconstruction with Transient Anchors for Long-Horizon Visual Mapping
Peilin Tao, Chong Cheng, Yuansen Du +8
Long-horizon online visual mapping requires continuous camera-motion and scene-geometry estimation under bounded computation. Recent feed-forward 3D reconstruction models provide s…
PlanaReLoc: Camera Relocalization in 3D Planar Primitives via Region-Based Structure Matching
Hanqiao Ye, Yuzhou Liu, Yangdong Liu +1
While structure-based relocalizers have long strived for point correspondences when establishing or regressing query-map associations, in this paper, we pioneer the use of planar p…
MGSfM: Multi-Camera Geometry Driven Global Structure-from-Motion
Peilin Tao, Hainan Cui, Diantao Tu +1
Multi-camera systems are increasingly vital in the environmental perception of autonomous vehicles and robotics. Their physical configuration offers inherent fixed relative pose co…
PolyRoom: Room-aware Transformer for Floorplan Reconstruction
Yuzhou Liu, Lingjie Zhu, Xiaodong Ma +4
Reconstructing geometry and topology structures from raw unstructured data has always been an important research topic in indoor mapping research. In this paper, we aim to reconstr…
