AI-Powered Waterhemp Detection and Stress Monitoring in Corn Farms

About the Project

Waterhemp is a highly competitive weed that threatens corn production by competing with crops for water, nutrients, light, and space. Its rapid growth and adaptability make early detection essential for effective weed management and reducing potential yield losses.

As part of our internal research and development initiatives, Saiwa explored the use of drone imagery and artificial intelligence to identify waterhemp infestations and assess corn field conditions. This work contributed to the development of our Waterhemp Detection service within the Sairone Weed and Invasive Plant Control solution.

Our Approach

Saiwa collected aerial RGB images of corn fields using drones and developed a semantic segmentation approach to classify different regions within the images. Unlike object detection, semantic segmentation assigns a class to each pixel, enabling the model to delineate areas with different vegetation characteristics.

The project workflow included:

• Drone Data Collection: Capturing aerial images of corn fields through our own data collection process.
• Image Annotation: Labeling field regions using Sairone's annotation tool to prepare training data.
• AI Model Development: Training a semantic segmentation model to distinguish waterhemp-infested areas, healthy corn, and stressed corn.
• Model Evaluation: Comparing model predictions with annotated reference images to assess its ability to identify the different field regions.

Results and Applications

The developed model demonstrated its ability to distinguish waterhemp-infested areas from healthy and visibly stressed corn in drone imagery. This approach provides a foundation for more targeted weed management, field monitoring, and crop health assessment.

By combining weed identification with crop condition analysis, this research also explored opportunities to support yield estimation and track changes in field conditions over time.
