Abstract
- Real-time 3D scene reconstruction has attracted a great amount of attention in the fields of augmented reality, virtual reality and robotics. Previous works usually assumed slow sensor motions to avoid large interframe differences and strong image blur, but this limits the applicability of the techniques in real cases. In this study, we propose an end-to-end 3D reconstruction system that combines color, depth and inertial measurements to achieve a robust reconstruction with fast sensor motions. We involved an extended Kalman filter (EKF) to fuse RGB-D-IMU data and jointly optimize feature correspondences, camera poses and scene geometry by using an iterative method. A novel geometry-aware patch deformation technique is proposed to adapt the changes in patch features in the image domain, leading to highly accurate feature tracking with fast sensor motions. In addition, we maintained the global consistency of the reconstructed model by achieving loop closure with submap-based depth image encoding and 3D map deformation. The experiments revealed that our patch deformation method improves the accuracy of feature tracking, that our improved loop detection method is more efficient than the original method and that our system possesses superior 3D reconstruction results compared with the state-of-the-art solutions in handling fast camera motions.
