Traj-VLN: Learning Pixel-Space Interaction via Autoregressive Trajectory Generation
Changfei Fu, Guangcheng Chen, Wenjun Xu +3
The paper introduces a method that fine‑tunes vision‑language models to predict sequences of pixel coordinates, enabling an embodied agent to follow natural language navigation ins…
Can Single-View Mesh Reconstruction Generalize to Robot Camera Rotation?
Yu Zhan, Guangcheng Chen, Hanjing Ye +4
Single-view mesh reconstruction predicts object meshes and spatial layouts from a single observation, making it attractive for fast robot spatial reasoning and real-to-sim digital…
FLM-Occ: Feed-forward Likelihood Maximization for Efficient Indoor Occupancy Prediction
Guangcheng Chen, Lihuang Fang, Huaqi Tao +3
Recent indoor occupancy prediction methods adopt Gaussian primitives as a sparse 3D representation for computational efficiency. However, their training relies on voxel classificat…
Hierarchical Visual Relocalization with Nearest View Synthesis from Feature Gaussian Splatting
Huaqi Tao, Bingxi Liu, Guangcheng Chen +3
Visual relocalization is a fundamental task in the field of 3D computer vision, estimating a camera's pose when it revisits a previously known scene. While point-based hierarchical…
PISR: Polarimetric Neural Implicit Surface Reconstruction for Textureless and Specular Objects
Guangcheng Chen, Yicheng He, Li He +1
Neural implicit surface reconstruction has achieved remarkable progress recently. Despite resorting to complex radiance modeling, state-of-the-art methods still struggle with textu…
