DH3D
A deep learning approach that unifies global place recognition and local 6DoF pose refinement for robust relocalization in large-scale 3D point clouds.
What is DH3D?
DH3D is a deep learning framework for 6-degree-of-freedom (6DoF) relocalization in large-scale 3D point clouds. It solves the problem of determining a camera's precise position and orientation within previously mapped environments by unifying global place recognition and local pose refinement. The system learns hierarchical 3D descriptors directly from raw point data, enabling robust performance across different sensor types including LiDAR and visual SLAM systems.
Researchers and engineers working on robotics, autonomous vehicles, augmented reality, and 3D computer vision who need robust relocalization capabilities in large-scale environments. This includes those developing SLAM systems, navigation algorithms, and 3D scene understanding applications.
Developers choose DH3D because it provides a unified architecture that handles both global retrieval and local refinement in a single forward pass, offers strong generalization across different point cloud sources without fine-tuning, and achieves competitive results against state-of-the-art approaches while being more efficient than separate systems.
