چکیده انگلیسی


- The precise determination of the repose angle of granular materials was presented.
- To determine the value of the angle of repose the photogrammetric method was used.
- For the results obtained, the measurement uncertainty was estimated.
- Factors affecting the measurement uncertainty were identified.

The paper addresses a vitally important issue of precise determination of the angle of repose of granular materials. For calculation of the said angle, a photogrammetric 3D coordinate measurement method has been proposed. With the view of method verification, 600 independent measurement results were obtained, based on which the angle of repose of examined plant granular materials (triticale) was determined with a statement of the associated measurement uncertainty. The conducted analysis has shown that the proposed method is useful and capable of low (as for biological materials) measurement uncertainty congruent with the requirements of automated systems, and as such may be helpful in laying down the standard specification for measuring of the angle of repose, using coordinate metrology.
