An approach is described for automatic assessment of crop and weed area in images of widely spaced (0.25 m) cereal crops, captured from a tractor mounted camera. A form of vegetative index, which is invariant over the range of natural daylight illumination, was computed from the red, green and blue channels of a conventional CCD camera. The transformed(More)
Certain experimental horticultural operations require an autonomous vehicle capable of navigating through a field of crop plants. An image analysis system exists which can locate the crop row structure, but simple reactive control of the vehicle on the basis of this data would not be sufficiently reliable; instead a multisensor data fusion based approach is(More)
