Better environment through precision farming

Herbicide spraying is necessary to optimize crop production in cereal fields. Full field spraying is however not necessary if the weed-infected areas can be detected before spraying. By treating only weed-infected areas, the herbicide usage can be reduced by as much as 35%, providing both environmental and economic benefits.

In collaboration with DAT AS, Adigo AS and the The Norwegian Institute for Agricultural and Environmental Research, SINTEF has therefore developed a camera-based system for on-line mapping of weeds in cereal fields. We have shown that image processing techniques can be used to differentiate between cereals and weeds under variable outdoor conditions. This allows for automatic control of the spraying nozzles based on the detected weed coverage.
