Short Summary

This study explores the potential of unmanned aerial vehicle (UAV) remote sensing for rapid and accurate assessment of winter wheat water content using multi-sensor fusion and automated machine learning.

Objective

• Investigate the feasibility of UAV-based remote sensing for monitoring winter wheat water content with high accuracy and efficiency.

Study Configuration

• Spatial Scale: Field-scale, focusing on a specific winter wheat crop.
• Temporal Scale: During flowering and filling stages under six irrigation treatments.

Methodology and Data

• Models used: Automated machine learning (AutoML) framework for regression model establishment.
• Data sources: High-resolution canopy remote sensing images from UAVs equipped with multispectral, RGB, and thermal infrared cameras; ground-truth sampling data.

Main Results

• Multi-sensor fusion achieved the highest accuracy in predicting winter wheat moisture content (MC), outperforming single-sensor approaches.
• During the filling stage, the TIR sensor showed the best performance (R2 = 0.812, MAE = 0.0204, RMSE = 0.0274).
• AutoML enabled high-accuracy prediction with minimal human intervention.

Contributions

• This study provides an effective means of monitoring winter wheat water content using UAV-based multi-sensor remote sensing.
• The use of AutoML enhances the precision of crop water monitoring and advances precision agriculture.
