Usage of flying robots for monitoring nitrogen in wheat crops

Abstract

The article deals with the application of remote sensing of agricultural plantations for assessment of their nitrogen fertilizer provision. The basic technologies of remote sensing used today, their advantages and disadvantages are described. A new calibration method for images obtained from sensors placed on the platform of UAV in unstable illumination based on EXIFF data file, such as size Light Value, is proposed. In terms of agrochemical permanent study area, I have received experimental data on the spectral characteristics of wheat and verified the proposed method. The expediency of development of specialized vegetation index during the use of UAVs in the visible range of the spectrum is justified. Based on the results, a neural network has been created that determines the content of nitrogen under the image with regard to the developed method.
