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
The paper introduces M⁴World, a multimodal driving world model that generates synchronized surround-view video and LiDAR streams while allowing fine-grained, interactive manipulati…
Anchor3R: Streaming 3D Reconstruction with Transient Anchors for Long-Horizon Visual Mapping
Peilin Tao, Chong Cheng, Yuansen Du +8
Long-horizon online visual mapping is a core capability for robot perception, requiring continuous camera-motion and scene-geometry estimation from visual streams under bounded mem…
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…
