3D Visual-Spatial Perception

Learning-based Visual Localization
Our research centers on learning-based visual localization, which aims to infer precise camera poses using deep learning techniques. Among various approaches, we explore Scene Coordinate Regression (SCR)—a method that predicts dense or sparse 3D scene points directly from sensor data like 2D images or LiDAR scans. This enables robust localization by linking 2D observations with the 3D world geometry.
Privacy-Preserving Visual Localization
Developing techniques that enable visual localization while protecting privacy concerns through methods like paired-point lifting and 3D ray clouds.
3D Object Reassembly and Reconstruction
Reconstructing the original shape of heritage ceramics from multiple fragments using advanced 3D modeling and matching techniques.
