This camera sees both Blue Light and Infrared (IR) Light with no cross talk between bands. It is most often used as a single camera NDVI solution for assessing where plants are located in agricultural surveying. By processing the resulting image, you can see the locations of varying levels of vegetation health and where there are no plants.
Camera captures a photo every 3 seconds. For best results, we recommend a survey overlap of at least 85% front-lap and 70% side-lap and a maximum 5f/s (1.5m/s) speed for every 65ft (20m) of altitude (AGL).
We picked leaves from the same plant in 4 levels of health and arranged them on our board from top to bottom: newest growth, normal healthy growth, dying growth, and dead leaves that had fallen off. The leaves were placed on black painted particle board on grey cement and photographed in two groups from a height of about 5 feet. The leaves on the left side of the board were placed so that the side normally facing towards the sun is up and on the right side they were flipped over revealing the bottom of the leaf. Up to 4 MAPIR cameras were mounted on the underside of the 3DR SOLO in our Quad mount and the entire UAV handheld while photos were captured. The first group contained a Red, Green, Blue and Infrared MAPIR camera. The second group contained a Visible Light and NDVI dual-band MAPIR camera.

Once you have the above original photos cropped and aligned in your editing program (video coming soon to show how to do this easily), you will want to proceed to post processing them.
