Visual Indoor Positioning with a Single Camera Using PnP
This paper introduces an accurate and inexpensive method for localizing a calibrated monocular camera in 3D indoor environments. The objective of this work is to localize in 6 degrees-of-freedom (6 DOF) in the presence of ...
Registration of Noisy Point Clouds Using Virtual Interest Points
A new method is presented for robustly and efficiently registering two noisy point clouds. The registration is driven by establishing correspondences of virtual interest points, which do not exist in the original point ...
Mobile LiDAR-Based Convergence Detection in Underground Tunnel Environments
This paper presents a mobile LiDAR-based method for remotely identifying convergence (i.e., naturally occurring deformation) in excavated underground tunnel environments. A mobile LiDAR system is used to collect and generate ...
