Application of non-metric digital cameras to control the volume of soil displaced when performing earthworks

Abstract

Moving soil during earthworks at a construction site requires its accounting and control. For this, expensive geodetic methods are widely used, while accounting and control must be performed with high accuracy and frequency. In practice, the use of terrestrial stereophotogrammetric survey can provide a high frequency and accuracy of the results obtained. The traditional stereophotogrammetric survey at this stage undergoes significant changes with the introduction of digital technologies, which allow it to be used more widely. It is proposed to use non-metric digital cameras when performing terrestrial stereophotogrammetric surveys, which will let to reduce the cost of performing the measurement works, as well as to increase the efficiency of field works. The main indicator of the possibility of using the non-metric digital cameras is their resolution, which allows ensuring the accuracy of definitions and acceptable parameters for their calibration.
