| Abstract/Contents: | "Weed control is an important part of turfgrass management, and the chemical method is both the most effective and economically viable. However, the widespread use of blanket herbicide applications has harmful effects on the environment and reduces the aesthetic look of the turfgrass. To mitigate these issues, targeted herbicide applications can reduce herbicide usage and minimize environmental harm. While various researchers have explored deep learning for weed detection in turfgrass, there remains a need to utilize unmanned aerial system (UAS) imagery for weed detection and localization, specifically targeting individual annual bluegrass (Poa annua L.) plants. In this research, we have developed a machine learning-based framework for weed detection and localization for precision herbicide application in turfgrass. Data was collected at different growth stages of annual bluegrass in Deer Park, Texas, with the specific objective of identifying and localizing annual bluegrass in turfgrass. We used the You Only Look Once (YOLO) deep learning model for weed detection, and a geotransformation function was used to convert image coordinates into global coordinates for site-specific herbicide applications to manage individual weed plants in turfgrass using drones, robots, and GNSS-guided boom sprayers. The results showed that the YOLOv7-w6 model had a detection accuracy of 78% compared to the YOLOv5l (68%), and YOLOv8l (66%). Once the model detects weeds in a photo, geotransformation transforms the center pixel of the bounding box into the latitude and longitude of each weed plant and achieves sub-centimeter-level accuracy; however, its performance depends on the accuracy of the orthophoto georeferencing. The developed model can be utilized for site-specific herbicide applications to manage individual annual bluegrass plants in turfgrass using drones, robots, and GNSS-guided boom sprayers. Future improvements will include real-time weed detection and testing the model's robustness at different growth stages and with various turf species." |
