3 Application Cases

Evaluation of the Late Growth Trend of Winter Wheat:The following figure shows the RGB image, NDVI and PSRI images at heading stage, NDVI and PSRI images at maturity stage. By extracting the reflectance spectral index, it reflects that from heading to maturity stage, the nutritional growth of wheat basically stops, the growth vitality significantly decreases, and the maturity increases significantly, indicating that it is about to enter the harvesting stage.
