NDVI Cameras with Drone

NDVI is a simple metric which indicates the health of vegetation. When near infrared hits the leaf of a healthy plant it is reflected back into the atmosphere. As the amount of chlorophyll produced in a plant decreases less near infrared is reflected. This can be used to see the overall health of a crop. The NDVI algorithm compares the reflected intensities of near infrared (NIR) and visible light 

How Does DroneDeploy Calculate NDVI?

Standard cameras capture Red, Green, and Blue light.

Modified cameras capture some combination of Near Infrared, Red, Green, and Blue light depending on the model.

There are two options for cameras

1. Use a standard RGB camera with the VARI algorithm. *RGB Plant Health maps are only significant when using the VARI algorithm. The VARI algorithm can be used to see the "greenness" of a crop.
2. Purchase a modified camera that captures Near Infrared Light.

Intelligent Agriculture is the trend of all over the world. And the intelligent drone act as a important role in this world plan.

Agriculture spraying drone can replace the traditional pesticide sprayer and it's speed is 40times of the traditional sprayer. It will save 90% water and 30%-40% pesticide. Small droplet diameter make the pesticide more well-distribute and improve the effect. At the same time, it will make the people faraway from the pesticide and reduce the pesticide remain of the crop.
