Abstract
In this work, we evaluated a family of You Only Look Once (YOLOv5) object detection models for real-time detection of weeds in soybean fields. Based on the results generated by the detection, agricultural inputs can be applied to the identified regions of interest, lowering production costs by reducing the average number of sprayings and contributing to ecological balance and environmental preservation. We used the UAV to fly over three agricultural areas at an altitude of 10 m. Thus, we created a new dataset of 4129 annotated plant samples, which can serve as a baseline for weed detection in soybean crops. We considered four metrics to evaluate the classification results and three to evaluate detection results. Experimental results showed low average error rates in almost all test scenarios. YOLOv5s6 produced the best results among the evaluated models, obtaining MAE, RMSE, and R2 rates of 1.14, 1.67, and 0.93, respectively. We also demonstrate how the model can be deployed as part of an end-to-end system for herbicide application.
期刊介绍:
The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics:
-Abiotic damage-
Agronomic control methods-
Assessment of pest and disease damage-
Molecular methods for the detection and assessment of pests and diseases-
Biological control-
Biorational pesticides-
Control of animal pests of world crops-
Control of diseases of crop plants caused by microorganisms-
Control of weeds and integrated management-
Economic considerations-
Effects of plant growth regulators-
Environmental benefits of reduced pesticide use-
Environmental effects of pesticides-
Epidemiology of pests and diseases in relation to control-
GM Crops, and genetic engineering applications-
Importance and control of postharvest crop losses-
Integrated control-
Interrelationships and compatibility among different control strategies-
Invasive species as they relate to implications for crop protection-
Pesticide application methods-
Pest management-
Phytobiomes for pest and disease control-
Resistance management-
Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
