For open-pit mines, calculating the amount of excavation is a problem that cannot be avoided. An open pit mine in Yunnan is handed over to the construction party for excavation and mining, and the owner settles the project according to the amount of excavation. Therefore, the owner and the construction party need to calculate the volume change once a month and then determine the excavation amount according to each other. In this process, the surveyor involved is typically to use RTK to measure the detail over the site and then form the topographic map for the calculation of the excavation amount.
U-Arm is a 3D terristrial laser scanner that is independetly developed by SureStar. It is able to acquire high-precision 3D data with a maximum range of 3600m, fully meeting the requirement of a mid-long range scan. It can be used for topographic surveying, enginering survey, deformation monitoring and vegetation survey. The equipped self-developed software UIUA can assist in the collection and processing of massive point cloud data.
