Abstract
Soil volume is an important reference value that is often determined through standardized sampling cylinders. Methods exist for measuring missing soil volume, but they either modify the sample or are time-consuming. Our new method uses structure-from-motion photogrammetry to create a 2.5D model of the soil-filled sampling cylinders from which the missing volume can be determined. We quantified the influence of different lighting conditions, the number of pictures taken, the type of camera, and of soil texture. This method provided reproducible and robust results, making it an effective alternative to previous methods.
