Comparison of Terrestrial Laser Scanner (TLS) and Unman Aerial Vehicle (UAV) For Volume Determination in Mae Moh Mine, Lampang

Abstract

The aim of this study is to compare Terrestrial Laser Scanner (TLS) and Unmanned Aerial Vehicle (UAV) for volume determination. Nowadays, TLS is a high accuracy equipment for coal and overburden waste volume determination in Mae Moh mine, Lampang province. UAV is also used to measure coal and overburden waste volume according to aerial photogrammetry theory by using Wingtra One fixed-wing UAV with GNSS Post Processing Kinematic (PPK) and Ground Control Point (GCP). Both equipment operated in three study areas in Mae Moh mine pit. The result of comparison indicated volume per area different less than 8 cm. Hence, it is acceptable for UAV to be used in a common accuracy requirement work, which can save time to operate and cover larger areas in each operation.
