DRONES FOR PRECISION AGRICULTURE
Crop Health Analysis
Multispectral sensors capture information that cannot be seen with the human eye, enabling early detection of issues like disease, water stress, pest infestation, nutrient deficiencies, and more. The specific filters on multispectral cameras highlight changes in chlorophyll content in plants, which is oftentimes an indicator of disease or stress.
With a multispectral camera, variation in vegetation becomes obvious. Analytics and outputs from this imagery can be used to direct teams for ground-truthing, targeted fertilizer or pesticide applications, precision thinning, and many more applications.
WHAT MULTISPECTRAL SENSORS CAPTURE
Light Energy from the sun is either:
- Absorbed
- Transmitted
- Reflected
Sensor captures light reflected off the plant canopy.
That light is captured in five spectral bands:
- Blue
- Green
- Red
- Red-Edge
- Near Infrared
