Abstract

Described is the development and testing of a robust vegetation detector for mobile robot navigation. A multispectral sensor was created out of a near-infrared and a visible light video camera. Vegetation was then detected by subtracting each pixel in the red channel of the visible-light image from the corresponding pixel in the near-infrared image and thresholding the result. This computationally-efficient technique has been verified to be a robust chlorophyll detector in natural environments.
