Abstract
This paper outlines a two phase experiment evaluating the accuracy of volumetric calculations using a commercially available drone and structure-from-motion (SfM) software. In the first phase, a large cardboard pyramid with a known volume was used to simulate a stockpile. Using georeferenced images collected by a Phantom 4 Pro drone and the SfM software ContextCapture, the computed volumes ranged between 1.5% and 3.3% of the actual volume. In the second phase of the experiment, a photometric survey was created of a large SCDOT borrow pit. The volumetric calculations were computed using conventional survey practices and with drone collected images. There was a 9.8% difference between the two methods with the drone base model providing significantly higher model resolution and number of data points.
