Study on Application of Terrestrial 3D Laser Scanning Technology in the Calculation of the Fine Earthwork

Supported by terrestrial 3D laser scanning technology, by using the GPS RTK technology as the verification. Explored the application of terrestrial 3D laser scanning technology in the calculation of fine earthwork, including the whole process from program design, pre-organization, field measurements applied to the calculation and submit of indoor operation results. In addition, Lanhaiwan project in xi’an of shannxi province was taken as a case to introduce detailed processes of fine earthwork calculation, The results show that the terrestrial 3D laser scanning technology can be well used for accurate measurement of the earthwork.
