Abstract: Abstract With the continuous advancement of urbanization process, the number of large-scale commercial complexes and other buildings continues to increase. As an important part of construction, the excavation of foundation pits also has increasingly high requirements for earthwork measurement and progress management. Currently, manual measurement is mainly used for earthwork excavation, utilizing total stations and Global Navigation Satellite System (GNSS), but this method has problems such as low accuracy, low work efficiency, and high costs. In this study, a scheme for earthwork calculation based on drone oblique photography and real-time management of earthwork excavation progress was proposed, which can improve the efficiency of terrain surveying and the accuracy of earthwork calculation, while enabling real-time monitoring without affecting construction. The experimental results demonstrate that the proposed method has good applicability for earthwork excavation calculation, and further research will be conducted in conjunction with other technologies to continue to improve calculation efficiency and accuracy.
