Check out my work here for the latest in applying drones for use in NDVI Mapping applications using Near-Infrared (NIR) Converted cameras and custom dual-bandpass filters for capturing vast amounts of images that can be processed in commercial or custom programs (in Python and Matlab)

I also provide code for use with NIR images for processing in GITHUB:

Hi

I'm thinking of using an ESP32-CAM for airborne NDVI. This module has a 2M pixel camera, a 32-bit microcontroller and an SD card socket. It weighs less than 10g and is readily available for about $10

It should be possible to remove the IR blocking filter and add an external red filter. Please does anybody have experience of using the ESP32-CAM for NDVI monitoring applications?

Thanks. Mike.

Since posting the above I have been able to remove the IR blocking filter and add a red filter. Obtained some 'interesting' results using Infragram but need to more fully understand what each of the many OV2640 setting options does. Anybody know where I can find this documentation?

Is this a question? Click here to post it to the Questions page.
