This little project aims to provide an easy-to-use solution for the Infragram DIY Plant camera kit from PublicLab.
The program reads out the Infragram camera and processes the image using the NDVI Analysis, assuming that the infrared is in the red channel, and the total visible light is in the blue channel. This is valid for the Infragram camera.
Video4Linux (by default included in most Kernels)
libjpeg is also included in most distros by default (Tested in Ubuntu 18.04 and Arch Linux)
Compile the programs using
make install is not (yet) supported, because it's still experimental.
This repository comes with two main programs:
ndvi- Process a given JPEG image
infragram- Read picture from camera and process the image
The most basic usage is
# Capture picture, process is via NDVI and write it to 'ndvi.jpeg' ./infragram ndvi.jpeg
You can keep the camera picture by providing a second jpeg file as program parameter
# Same as above, but keep the campera picture as 'camera.jpeg. ./infragram ndvi.jpeg camera.jpeg
If you are having more than one camera devices (e.g. a webcam) you will need to configure the right input device via
# Configure input device via '-i DEVICE' ./infragram -i /dev/video1 ndvi.jpeg
Putting all together:
# Read from /dev/video1, store NDVI image as 'ndvi.jpeg', the camera image as 'camera.jpeg' and provide verbose output ./infragram -v -i /dev/video1 ndvi.jpeg camera.jpeg
For more informations type
This simple program takes a JPEG picture and performs the NDVI analysis on it
# Take 'camera.jpeg' and write result to default file ('ndvi.jpeg') ./ndvi camera.jpeg # Process 'camera.jpeg' but write result to 'output.jpeg' ./ndvi camera.jpeg output.jpeg
Currently only one colormap is supported: Red to green, where red is the minimum and green is the maximum
