Abstract
Multispectral imagery for sensing applications are very pricey and sometimes not available. This
paper shows the development of an imaging system that captures near infrared light and visible light
to produce a Normalized Difference Vegetation Index (NDVI) image. It utilizes the Raspberry Pi
microcomputer which was capable of performing different image processing techniques to process
images captured by the multi-spectral band digital cameras. The system applied image rectification,
and stereo correspondence prior to calculation of the NDVI. Images produced were validated and are
70 percent comparable to an existing system.
