Surveying of the volumes of excavated rock, dumps and warehouses of ore, coal and inert materials is a mandatory procedure at mining enterprises. It is used to keep records of production, settlements with contractors, and reporting by subsurface users. Traditional technology involves manual recording of characteristic points with a total station or GNSS receiver, followed by on-camera calculation. This requires a lot of labor, is associated with the presence of personnel in hazardous areas (ledges, slopes, warehouse surfaces) and provides limited measurement detail. Modern photogrammetric photography makes it possible to obtain detailed digital models of the surface, however, the calculation of volumes using such models remains largely manual. The operator selects the boundaries of objects manually, determining the reference surface requires expert solutions, processing multi-time models and preparing reports takes a lot of time. The lack of an automated tool hinders the use of photogrammetry in surveying.
Reducing the time of surveying calculations from several days to hours by automating the allocation of objects and calculations. Improve the accuracy and reproducibility of the results, as subjective manual operations are eliminated. Reducing production risks, staff do not need to be in dangerous areas when shooting. Increasing the transparency of production accounting and settlements with contractors. Acceleration of preparation of accounting documentation for subsurface users. The ability to integrate the technology into existing photogrammetric processing pipelines and scale the solution to enterprises in the mining industry of the Republic of Kazakhstan

Purpose and description of task (project)
It is required to develop a solution for automated volume calculation based on digital surface models, which are constructed using photogrammetric processing of aerial photography data. As part of the task, it is necessary to: implement automatic allocation of the boundaries of accounting objects (warehouses of bulk materials, dumps, excavation sites) on a digital surface model and an orthophotoplane; develop algorithms for correctly determining the reference surface for calculating volumes, including for complex terrain; ensure the calculation of excavation and embankment volumes by comparing different digital models of the same territory; to filter out noise and foreign objects (machinery, structures) that affect the accuracy of calculations; to ensure that the solution works on high-resolution models and large areas; to provide for the formation of accounting documents based on the results of calculations (volume statements, excavation and embankment cartograms); to provide for the possibility of embedding the solution in the existing photogrammetric processing pipeline as an application module.
