Assessment of Difference in Structure from Motion for Stockpile Volume Estimation using UAV Approach

Abstract The software for processing the photogrammetry is increasingly capable of producing a high-quality 3D model DEM, DSM, and DTM from an aerial photo measuring volume material. Nowadays, UAV technology has been rapidly used stockpile calculation mining construction industry. purpose this study to compare image using three different with conventional method GPS as reference. result obtained processed CIVIL3D act base measurement obtain which Pix4D, Agisoft, SimActive’s Correlator3D. analysis compared each selected accuracy achieving below 3% error referenced stockpile. 12 GCP were placed around area test difference between numbers results. acquisition taken at 10 meter altitude 20 Phantom 4 pro set Pix4Dcapture circular mission.

Overall, can conclude not only flight affected, type affecting number clouds but
