ALGORITHM OF OPTICAL MONITORING FOR REAL-TIME EVALUATION OF GRAIN FRACTIONATION EFFICIENCY BASED ON THE STRUCTURAL CHARACTERISTICS OF THE FLOW
Serhii STEPANENKO – Senior Researcher, Doctor of Technical Sciences, Head of the Department of Mechanical and Technological Problems of Harvesting and Post-Harvest Processing of Grain and Oilseed Crops of the Institute of Mechanics and Automation of Agro-Industrial Production of the National Academy of Agrarian Sciences of Ukraine (Hlevakha, Ukraine; e-mail: Stepanenko_s@ukr.net, https://orcid.org/0000-0002-8331-4632).
The problem of improving the efficiency of quality control in grain fractionation processes within post-harvest grain handling is addressed. It has been established that conventional methods for evaluating the quality of obtained fractions, which rely on laboratory sample analysis, are labor-intensive, time-delayed, and incapable of providing real-time monitoring of the technological process. This necessitates the development of new approaches based on modern digital technologies.
An algorithm for optical quality control of the grain fractionation process is proposed, based on the application of computer vision techniques and analysis of the grain flow structure. The algorithm includes the formation of a stable optical scene, acquisition of digital images of the grain flow, their preprocessing, grain kernel segmentation, extraction of geometric and optical features, classification of objects into fractions, and subsequent statistical analysis of the obtained data.
A distinctive feature of the proposed approach is the use of structural characteristics of the grain flow to evaluate the efficiency of the fractionation process. Based on the determination of the quantitative and qualitative composition of fractions, integral indicators are introduced to characterize fraction purity, impurity content, and the degree of material separation. This enables an objective assessment of process quality directly during operation.
The developed algorithm enables the implementation of an automated monitoring and control system for grain fractionation. The use of feedback based on optical analysis results allows for real-time adjustment of equipment operating parameters, including the feed rate of grain material and separation settings, thereby improving process efficiency and reducing losses. The proposed approach provides a foundation for the development of intelligent quality control systems and digital twins of post-harvest grain processing operations.
