P4P camera with IR for agricultural use

[Droneted]

I have a Phantom 4 Pro camera for agricultural use. Wondering how this is used and if anyone might be interested. I have no idea what it's value is. Thoughts?

Any idea who altered camera it seems to be very specialized for maybe only one task only certain crops only

Chlorophyl reflects Infra red brilliantly, and IR cameras are often used in agriculture, siviculture, and other environmental sciences. Yours is almost surely an IR camera. Image sensors generally are sensitive to nonvisible IR light, and to prevent anomalies in the recorded image, IR is often filtered out. Sometimes a camera can be converted to IR by simply removing the filter or being manufactured without one. Yours might be one of those. Search NDVI (Normalized Difference Vegetation Index) which is the most well known application for IR in agriculture.

I know it has a special lens inside the camera head instead of the clear one. Everything has a red hue to it. It is kind of cool. I repaired a camera just like this last summer. He was using it to check crops

It can be converted back to a standard camera by changing the IR lens to a clear. Just got done doing it on one that I purchased, unknowingly for agriculture. Red hue.

I’m interested. Pictures? Camera only or including bottom shell.

This thread makes it sound like you could convert the camera on a P4P to infrared for vegetation by adding a red hue filter. It can’t be that simple, could it?

I'm afraid not. I'm not an optics guy, but I do know that IR, being a longer wavelength, focuses at a different distance behind the lens, and so to do it properly you'd have to modify the lens system as well. Also, since filters work by blocking light in selected parts of the spectrum, you can't add information with a filter, only subtract.

this is sort of what it looks like

I did a previous thread a couple months ago with the same exact problem. Had to go inside and replace the IR lens with a clear.

Thanks, that’s along the track of my thoughts as well. Have looked into it further, and it is possible to convert, but you’ll have wrenove the entire original lense and replace with an IR lens. That would I guess dedicate that bird to only Ir flights.

Look familiar? Red IR lens before switch.
