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
