Robot Completes 3D Scan of Silver Mine in Mexico
     

3D-R1
is a remote operated survey vehicle equipped with a Riegl LMS-Z laser
scanning system. The robot recently
completed a scan of the San Jose silver mine in Mexico where it
spent 3 and half days mapping 2.2km of "underground drives, stopes
and access ramps", doing more than 80 scans per day and producing
nearly 100 million data points. In less the a month the mining company
was able to replace old mine drawings with accurate 3D data that
"corresponded exactly with existing topographic aerial photographs
and contour maps of the mine site".
