TRAJECTORY ADJUSTMENT OF MOBILE LASER SCAN DATA IN GPS DENIED ENVIRONMENTS
MLS mobile mapping LiDAR long tunnel survey
2016/3/25
Mobile mapping often occurs in environments with poor or no GNSS signal reception (tunnels, urban canons, canopy …). Most mobile scanning systems are equipped with tactical grade inertial systems, GNS...
Automatic Matching of Terrestrial Scan Data Using Orientation Histograms
LIDAR Laser scanning Point Cloud
2015/12/16
Terrestrial laser scanners allow to obtain accurate 3d model of the object as a point cloud. Real objects should be scanned with
different instrument positions and then scan data is registered into t...
