I have not had a chance to review this report on 3D Laser Scanning Equipment yet, but I wanted to get this out there as soon as possible as it will certainly be of interest to not only those in the transportation industry, but 3D laser scanning in general.
The Illinois Center for Transportation at the University of Illinois at Urbana-Champaign has released a report that determines the tangible costs versus benefits and the manpower savings realized by using the 3-D laser scanning in place of or in conjunction with conventional surveying methods. This report reviews surface topography mapping of bridge decks, bridge beam deflection scans, and detailed surface mapping of various structures.
The report used the Trimble TX5 laser scanner for the study.
Two projects were used for comparing manpower requirements for conventional surveying methods with those for 3-D laser scanning. Other projects were included in this evaluation under the objective of expanded use of the laser scanning equipment and included surface topography mapping of bridge decks, bridge beam deflection scans, and detailed surface mapping of various structures.
