Global Registration of Subway Tunnel Point Clouds Using an Augmented Extended Kalman Filter and Central-Axis Constraint
Because tunnels generally have tubular shapes, the distribution of tie points between adjacent scans is usually limited to a narrow region, which makes the problem of registration error accumulation inevitable. In this paper, a global registration method is proposed based on an augmented extended Kalman filter and a central-axis constraint. The point cloud registration is regarded as a stochast...

متن کاملTemporal Registration using a Kalman Filter for Augmented Reality Applications
Augmented Reality uses see-through head-mounted displays to superimpose synthetically generated information on a three-dimensional scene. Information is rendered in alignment with physical objects to enhance the user’s ability to perceive and interact with the world. A significant technical challenge related to Augmented Reality is determining the transformation that will correctly align the sy...
