A smart system for controlling invasive weed growth uses multispectral sensors and computer vision algorithms to detect and classify all plants in a field. After weeds are identified, a laser beam is used to eliminate or seriously damage the weeds. Sensing cameras are attached to an all-terrain robot or even a tractor add-on to find and target unwanted weeds.
“The robot shoots the leaves of the unwanted plants with short laser pulses, which causes a weakening in their vitality,” said University of Bonn researcher Julio Pastrana.
“It is thus predicted that we will no longer need to use herbicides on our fields and the environment will be protected,” added researcher Tim Wigbels.
