Volume computation of quarries in Vietnam based on Unmanned Aerial Vehicle (UAV) data

Abstract

The main objective of this study is to evaluate the accuracy of volumetric measurements carried out with the unmanned aerial vehicle (UAV) data in quarries in Vietnam. To accomplish this goal, GNSS/RTK and UAV technologies were employed to collect data at the same time in the Long Son quarry in Thanh Hoa. The data was used to establish DEMs, which were used to calculate the reserve of the quarry. The results of calculating the mine reserves showed that the difference between the two methods was 0.07%; Also, the difference in the height between the two average models was 3.5 cm. This result satisfies the requirements in the Vietnamese standards for mine surveying.
