UAVs and agriculture have had a technological marriage. Ever increasing demands on producers to maximuise crop production can now be enhanced by incorporating Aerial surveys into the crop production program. Early stages of diseased crops can be identified and treated before affecting whole fields or farms. Sensor development now means many tyupes of surveys can be carried out without taking machinery through the crops. Using various sensors we can do aerial mapping and imaging, plant counting, survey and land use assessment, plant health and height measurements, water quality and temperature, and NVDI
To determine the density of green on a patch of land, researchers must observe the distinct colors (wavelengths) of visible and near-infrared sunlight reflected by the plants. As can be seen through a prism, many different wavelengths make up the spectrum of sunlight. When sunlight strikes objects, certain wavelengths of this spectrum are absorbed and other wavelengths are reflected. The pigment in plant leaves, chlorophyll, strongly absorbs visible light (from 0.4 to 0.7 µm) for use in photosynthesis. The cell structure of the leaves, on the other hand, strongly reflects near-infrared light (from 0.7 to 1.1 µm). The more leaves a plant has, the more these wavelengths of light are affected, respectively. Equipped with special cameras and utilising post processing software our drone can give a staus on the health of a crop.
