Enhancing seeding efficiency using a computer vision system to monitor furrow quality in real-time

2025-04-27

AI Summary

In precision agriculture, poor furrow quality and uneven seeding—caused by crop residue accumulation, low temperatures, and “hair pinning”—compromise planting accuracy and seedling emergence. Existing row cleaners lack quantitative, objective evaluation methods, hindering their optimization and deployment. To address this, we propose a novel, vehicle-mounted, real-time video-based approach leveraging semantic segmentation to quantify furrow cleanliness. This method enables pixel-level classification of soil, crop residue, and machine components, and automatically extracts the furrow region—establishing, for the first time, an objective, comparable, and fully automated performance assessment framework for row cleaners. The approach significantly improves row cleaner selection accuracy, enhances seeding uniformity and stand establishment, and provides closed-loop feedback for intelligent seeding systems. It advances precision planting toward measurability, optimizability, and verifiability.

Abstract

Effective seed sowing in precision agriculture is hindered by challenges such as residue accumulation, low soil temperatures, and hair pinning (crop residue pushed in the trench by furrow opener), which obstruct optimal trench formation. Row cleaners are employed to mitigate these issues, but there is a lack of quantitative methods to assess trench cleanliness. In this study, a novel computer vision-based method was developed to evaluate row cleaner performance. Multiple air seeders were equipped with a video acquisition system to capture trench conditions after row cleaner operation, enabling an effective comparison of the performance of each row cleaner. The captured data were used to develop a segmentation model that analyzed key elements such as soil, straw, and machinery. Using the results from the segmentation model, an objective method was developed to quantify row cleaner performance. The results demonstrated the potential of this method to improve row cleaner selection and enhance seeding efficiency in precision agriculture.
