Abstract
Quantitative and qualitative determination of total volume and surface features of a soil specimen is important in geotechnical engineering. Available methods suffer from a variety of shortcomings such as sample disturbance, equipment calibration, and lack of precision. The Controlled Photogrammetry System (CPS) is based on Structure-from-Motion (SfM) to capture a series of photographs and transform the images into a referenced three-dimensional model.
